Description

Directional LED lamp for security light and security light fixture equipped with it {DIRECTIVITY LED LAMP FOR SECURITY LIGHT AND SECURITY LIGHT HAVING IT}

According to the present invention, the socket is mounted on the security light fixture installed upward and illuminates in a direct downward direction and a downwardly inclined direction, while providing a plurality of substrates on which LEDs are mounted, and electrically connecting the substrates without wires, and lighting the LEDs. The present invention relates to a directional LED lamp for a security lamp and a security luminaire equipped with the same, which dissipate through the air in the protective cover of the security luminaire while preventing heat generated in the process from being transferred to the base of the lower part.

LED (LED) has the advantages of long life, low power consumption, high efficiency, high brightness, high-speed response characteristics, etc., compared to the conventional light source, and has recently been used as an LED lamp to replace the lamp of the security light fixture.

Among the luminaires that use such LED lamps, there are luminaires which are installed with the protective cover upward. In the case of such luminaires, the socket is also upward and the base of the lamp is downwardly screwed into the socket. Mounting a general lamp that illuminates in the opposite direction, the amount of light irradiated to the ground is significantly reduced, which reduces the lighting efficiency. Moreover, there is a problem that the periphery of the support for supporting the luminaire becomes a blind spot for lighting.

In order to solve the problem of lowering the lighting efficiency and the blind spot, a way of installing a luminaire downwardly under the end of the arm by installing a support having an arm, the upper part of the protective cover to protect the lamp It is a method of coating with a reflector, the downward reflection on the lamp itself by adopting a method such as installing a reflector, so that most of the light emitted from the LED is directed downward.

However, the method of installing the support with arm has the cost and difficulty of installing the existing support, and the method using the reflector coating or the reflector does not reflect 100% of the light efficiency. Deterioration, difficulty in designing a structure to accurately match the reflection direction, and difficulty in making a lamp or a luminaire large by separating the reflection position from the LED by a certain distance.

In order to solve this difficulty and efficiency reduction, a method of using a technique of forming a polyhedron of the substrate 100 on which the LED is mounted may be considered as in the LED lamp of Patent No. 10-0922946 shown in FIG. 1. That is, only the downward surface of the surface of a polyhedron is comprised by an LED substrate.

However, the above-described prior art has a component for supporting a polyhedron, that is, a base 400 fixed to a luminaire socket and a heat dissipation means 200 for dissipating heat into a lower component fixed to the glove 300. There is a problem in that the downward light is blocked by the dark light area directly below.

In addition, when the LED is turned on, heat is generated in the LED, the LED substrate, and the power substrate for supplying the DC power to the LED. In the above-described conventional technique, the heat dissipation means 200 is fixed to the base 400 so that heat is generated. The base 400 is to be delivered. Accordingly, a problem may occur in which the wires connected to the base 400 are disconnected and disconnected, and a problem may occur in which heat transferred to the base 400 is conducted to the socket of the luminaire to separate the wires connected to the socket.

In addition, the luminaire to which the LED lamp is mounted is protected by covering the LED lamp with a protective cover. At this time, the inner space of the protective cover is large enough to emit heat by convection and conduction by air in the inner space. Of course, the heat generated from the LED lamp is transmitted to the protective cover by the air filled in the inner space of the protective cover is released to the outside. However, according to the related art shown in FIG. 1, since the heat dissipation means 200 is fixed to the base 400 and is biased under the protective cover of the luminaire, the heat dissipation means 200 is not effectively released. In other words, it does not utilize the air inside the protective cover enough to release heat effectively.

In addition, also in the structure of the LED lamp, in order to effectively dissipate heat, the heat dissipation means 200 containing the power substrate should be close to the LED substrate 100. However, according to the prior art described above, the distance from the LED substrate 100 should be large enough to prevent the light from being blocked by the heat radiating means 200 as much as possible. ) Will not be absorbed sufficiently.

Meanwhile, in order to electrically connect the plurality of LED substrates 100 to each other, a protrusion-type first power terminal is formed on one LED substrate and a groove-type second power terminal is formed on the other LED substrate to form a first power terminal. Although the second power terminal is fitted to be electrically connected, the composition of the first and second power terminals makes it difficult to manufacture the LED substrate 100. That is, in general, the LED substrate 100 is plated on the surface according to the circuit pattern, and the inner surface of the through hole is plated when the through hole is an electric passage, so the process of forming a power terminal on the surface or the inner surface of the through hole is a basic process. It is done. Accordingly, it is difficult to form the projection and groove-type power terminal as in the prior art, it is difficult to compose only the basic process of the LED substrate, which makes it difficult to require an additional process in the manufacturing process of the general LED substrate 100.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are used to denote the same or similar components in other drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

2 to 6, the LED lamp according to the embodiment of the present invention, the LED substrate 100 is installed in the interior of the light-transmitting globe 10, like the conventional LED lamp and the lower portion of the globe 10 The base 20 is fixed in shape so that the base 20 can be inserted into a socket such as a security lamp and installed in the security lamp.

In general, a lamp employing an LED absorbs heat generated from the LED and the LED substrate to the heat dissipation member to radiate heat to the outside, but in order to cool the LED and the LED substrate more quickly, as shown in the drawing, the LED substrate ( When manufacturing the glove 20 to wrap and protect the 100, it has a sufficient internal space in addition to the space occupied by the LED substrate 100 and fill the gas into the internal space to release heat by conduction and convection by the gas do. That is, the heat generated from the LED and the LED substrate is transferred to the globe 10 by conduction and convection of the gas to be released to the outside.

Thus, unlike the conventional LED lamp having the LED substrate, the glove 10, the base 20 and the heat dissipation member, the present invention, the heat generated during the LED lighting process is not transmitted to the base 20. Is configured to dissipate heat to the outside while avoiding heat.

To this end, the present invention opens the upper portion of the glove 10 fixing the base 20 to the bottom to form a hole 11, the heat dissipation member 30 for heat dissipation in the upper hole 11 of the glove 10 To close the upper hole (11). In this way, the heat dissipation member 30 which is spaced apart from the base 20 with the glove 10 interposed therebetween is electrically connected to the base 20 by using an electric wire 61 crossing the inside of the glove 10 in a vertical direction. Connect.

In detail, the heat dissipation member 30 includes an inner space 32 closing the upper portion and having an open inner space 32 at the lower portion thereof to supply a power substrate 50 for supplying a direct current electricity required to light the LED 101. A plurality of heat dissipation fins 31, which are accommodated in the 32 and radially projected on the outer circumferential surface thereof, are provided to be capable of dissipating heat. According to the exemplary embodiment of the present invention, for the convenience of manufacturing the heat dissipation member 30, the heat dissipation member 30 is opened up and down, and then the upper opening is closed by the upper cover 33.

In addition, a substrate seating member 40 for fixing the LED substrate 10 to be fixed to the LED 101 mounted on the LED substrate 100 in a direct downward direction and a downwardly inclined direction is disposed below the heat dissipation member 30. Fix it.

To this end, the substrate seating member 40 is formed in the shape of an inverted pyramid with an upper opening, so that the upper opening edge can be fixed in contact with the lower opening edge of the heat dissipation member 30, The LED substrates 100 can be fixed to the side surfaces of the bottom surface 42 as well as the slope 41. In the embodiment of the present invention, the substrate seating member 40 has a shape of inverting the hexagonal pyramid up and down, and includes a total of seven LED substrates 100 including six slopes 41 and one bottom 42. The LEDs 101 which can be fixed and mounted on the seven LED substrates 100 respectively emit light in the glove 10 and illuminate in the direct and inclined directions.

On the other hand, in the upper opening of the substrate seating member 40, it is fixed as closed as the power substrate 50, the electric / electronic elements mounted on the power substrate 50 is directed upward, the power substrate ( The electrical / electronic elements of 50 are in the form of being accommodated in the inner space 32 of the heat dissipation member 30. Accordingly, heat generated from the power substrate 50 may be directly conducted to the heat dissipation member 30, but indirectly by heat conduction and convection of air filled in the internal space 32 of the heat dissipation member 30. It is delivered to the member 30 and discharged.

The LED substrate 100 fixed to the substrate seating member 40 is divided into a main LED substrate 110 fixed to the bottom surface 42 and a plurality of sub LED substrates 120 fixed to the slope 41.

The main LED substrate 110 is electrically connected directly to the power substrate 50. For example, as shown in the drawing, the main LED substrate 110 is connected to the main terminal 112 of the outer surface on which the LED 101 is mounted. After soldering one end, the other end of the electric wire penetrates through the main LED substrate 110 and also penetrates the bottom surface 42 of the substrate seating member 40 and withdraws into the substrate seating member 40. It is electrically connected to the fixed power board 50 as if seated in the upper opening of the seating member (40). Of course, the main terminal 112 is not only electrically connected to the LED mounted on the main LED substrate 110 but also electrically connected to the notch-type solder 111 formed on the edge of the main LED substrate 110.

The sub LED substrate 120 is electrically connected to the main LED substrate 110 to receive electricity from the power substrate 50 through the main LED substrate 110 to emit light. Of course, a circuit pattern is formed to mount the LED 101 on the surface of the sub LED substrate 120 that is exposed to the outside, and to electrically connect the LED 101 to the planar solder terminal 121.

According to the exemplary embodiment of the present invention, the sub LED substrate 120 may be electrically connected to the main LED substrate 110 by soldering without wires.

Specifically, the main LED substrate 110 is a polygon having the same number of sides as the number of the sub LED substrates 120, that is, the number of slopes 41 of the heat dissipation member 30. In the embodiment of the invention is formed as a hexagonal plate, the lower side of the sub LED substrate 120 is in contact with each side, at this time, the notch (notch) on the sides of the main LED substrate 110 in contact with each other (邊) ) And a notched solder terminal 111 formed inside the notch, and a planar solder terminal 121 formed on the surface exposed to the outside is provided on the side of the sub LED substrate 120. . That is, the planar soldering terminal 121 is formed on the surface exposed to the outside by mounting the LED to reach the rim, the notched solder terminal 111 is formed on the inner side of the notch after forming a notch on the rim This allows the LED to have a surface perpendicular to the surface on which the LED is mounted.

In addition, each side of the main LED substrate 110 extends to the outside so that the side on which the notch-type soldering terminal 111 is formed outward from the side of the sub-LED substrate 120 having the planar soldering terminal 121 formed thereon. The notched solder terminal 111 and the planar solder terminal 121 are in contact with each other. In other words, the notched solder terminal 111 and the planar solder terminal 121 have a predetermined area and are in contact with each other.

Accordingly, the notched solder terminal 111 and the planar solder egg 121 are soldered in contact with each other, thereby being electrically connected to each other. Here, when the state of the solder 130 by soldering in detail, the notch-type solder terminal 111 and the planar solder egg 121 is the surface of the substrate mounting member 30 and the thickness of the sub-LED substrate 120 Since they are spaced apart from each other and the edges are in contact with each other, there is no possibility of being electrically connected to the surface of the heat radiating member 30 even if soldering. That is, between the notched solder terminal 111 and the planar solder egg 121, even if a separate insulating material is not provided for insulation from the substrate seating member 30, which is generally formed of a material having high thermal conductivity and is electrically conductive. The electrical connection can be safely obtained by the soldering process alone.

Further, when soldering, the solder 130 is filled in the notch in which the notched solder terminal 111 is formed, so that the soldering state is also good.

As described above, the main LED substrate 110 is formed to contact the notch-type soldering terminal 111 and the planar soldering terminal 121 with each other. Referring to the drawings, the main LED substrate 110 has four sides. It extends slightly radially to have a form that is slightly larger than the bottom surface of the substrate seating member 40.

On the other hand, if the notched solder terminal 111 is formed on the sub LED substrate 120 and the planar solder terminal 121 is formed on the main LED substrate 110, the sub LED substrate having the notched solder terminal 111 formed ( 120 shall be extended.

In addition, the planar solder terminal 121 becomes part of a circuit pattern formed to mount the LED on the sub LED substrate 120, and the notched solder terminal 111 penetrates during the manufacturing process of the main printed circuit board. Since it can be formed by an electroless copper plating process to plate the inner surface of the sphere, the LED substrate (100: 110, 120) can be easily produced only by the manufacturing process of a general printed circuit board.

As described above, the LED lamp according to the present invention is fixed to the base 20 in the lower portion and the heat dissipation member 30 in the upper portion with the glove 10 in between, the substrate fixed to the lower portion of the heat dissipation member 30 By installing the power substrate 50 and the LED substrate 100 on the seating member 40, a separation distance between the power substrate 50 and the base 20 for the electrical supply is generated, the base of the power substrate 50 It is to be electrically connected to (20).

According to the present invention, by installing the conduit tube 60 standing up between the base 10 and the substrate mounting member 40, by wiring the electric wire 61 through the conduit 60, the base 10 and the power substrate ( 50) are electrically connected. Of course, the conduit 60 fixes the lower end to the base 20 and penetrates the lower portion of the glove 10 and the center of the main LED substrate 110 to fix the upper end to the bottom of the substrate mounting member 40. Therefore, when manufacturing the main LED substrate 110, a central hole 113 for penetrating the conduit 60 must be formed, and inserting and fixing the upper end of the conduit 60 to the bottom of the substrate seating member 40 Insertion hole 43 for forming to match the position of the central hole (113).

Meanwhile, the heat dissipation member 30 to which the load of the substrate seating member 40, the power substrate, and the LED substrate 100 is applied may be supported by the glove 10, but the substrate seating member 40 may be supported by the conduit 60. You can also support it. At this time, since the conduit 60 should not block the light emitted from the LED of the main LED substrate 110 if possible, it is preferable that the conduit 60 is formed thinly with sufficient supporting force, and, of course, a material having low thermal conductivity. It is good.

7 is a bottom perspective view of a security light fixture provided with a directional LED lamp for a security light according to an embodiment of the present invention.

Security light fixture 2 equipped with a directional LED lamp (A) for the security lamp according to an embodiment of the present invention, is installed on the upper end of the column (1), the socket (3) upwards to the base of the LED lamp (A) By mounting the screw 20 from above, the light emitted from the LED 101 of the LED substrate 100 is illuminated in the direct and downward inclined direction, the position and the column 1 ) Brightly illuminates the surroundings, but not at the top.

Accordingly, the present invention does not unnecessarily upwardly illuminate, and instead, only the light emitting light shines on the ground in the direction of direct and downward inclination, eliminating blind spots, minimizing the loss of light, and LEDs of small capacity. Even when the lamp A is used, the periphery of the column 1 can be brightly lit.

In addition, the LED lamp (A) according to the present invention intensively absorbs and releases heat generated by emitting heat using the heat dissipation member 30 installed so as not to be in direct contact with the base 20, a part of the heat generated Is emitted evenly through the entire surface of the glove 10, and the heat generated is weakly transmitted through the base 20. Accordingly, the heat transmitted to the socket 3 of the security light 2 is also weak, thereby preventing overheating of the internal electrical connection point of the socket 3 and improving durability.

In addition, the LED lamp (A) mounted on the socket (3) is wrapped with a protective cover (4), wherein the heat generated from the LED lamp (A) is conducted to the conduction of air filled inside the protective cover (4) and Since it is evenly distributed on the entire surface of the protective cover 4 by convection and discharged to the outside, the heat radiation efficiency is also high.

In describing the present invention, the LED lamp according to the present invention has been described as being mounted on a security lamp, but it is obvious that the LED lamp can be mounted on a garden lamp, door lamp, street lamp, etc. without being limited to the security lamp. One security light should be understood to include an LED lamp such as a garden light, door lamp, street light, and the like.

In addition, in the description of the present invention, it has been described that the socket is applied upward to the luminaire, but it is obvious that the socket is also applicable to the downward luminaire. That is, since the lamp is used downward and the luminaire for intensively illuminating the upper and upwardly inclined directions, the light is fixed by fixing the base 20 of the LED lamp A according to the present invention to the socket downward. It can be illuminated in an upwardly inclined direction and upward direction including the side. Here, the illumination to the side surface is because there is also the amount of light irradiated to the side surface by the light distribution by the light distribution curve of the LED mounted on the sub LED substrate 120.
