The present invention relates to a light emitting diode illumination lamp.

Technology development and demand for lighting lamps using light emitting diodes are gradually increasing.

A light emitting diode lighting lamp using a light emitting diode as a light source is an eco-friendly lighting device having high light efficiency because it can emit bright light while having low electric energy consumption.

However, the light emitting diode illumination lamp needs to effectively radiate heat generated from the light emitting diode. In the conventional light emitting diode illumination lamp, since a heat sink made of metal is mainly provided, the total weight is greatly increased and the manufacturing cost is increased.

The problem to be solved by the present invention is to provide a light emitting diode illumination lamp having a frame having a light and good heat dissipation effect.

The light emitting diode illumination lamp according to the embodiment of the present invention has a hollow polyhedral shape and has a metal heat sink, a plurality of light emitting diode substrates attached to an outer surface of the heat sink and a plurality of light emitting diodes mounted on the light emitting diode substrate. The light emitting diode module includes a light transmission cover surrounding the outside of the light emitting diode module, a frame made of a synthetic resin material on which the heat sink and the light transmission cover are mounted, and a power supply for supplying power to the light emitting diode.

The light transmitting cover and the frame may each have a cup shape, and the open portions may be fastened to face each other, and the heat sink and the light emitting diode module may be disposed in a space formed by the light transmitting cover and the frame.

The light transmission cover and the frame may be formed of a synthetic resin material, but the frame may be formed of a synthetic resin material having a higher structural strength than the light transmission cover.

The light transmitting cover may be formed of polycarbonate, and the frame may be formed of any one of ABS, PPS, and PPA.

The light emitting diode substrate attached to an outer surface of the polyhedral heat sink may have an area smaller than that of the outer surface.

The surface of the frame of the synthetic resin material may be coated with nickel.

Protrusions or grooves may be formed on the surface of the frame.

The light emitting diode lighting lamp according to another embodiment of the present invention may further include an anion module for emitting anion.

The anion module may include an anion generator for generating anion, an anion brush connected to the anion generator for emitting anion, and an anion cover for allowing anion emitted from the anion brush to be radiated forward.

The anion brush may be formed by twisting a plurality of fine metal wires in an entangled state in a longitudinal direction.

The plurality of thin wires may include thin wires formed of three or more kinds of metal materials.

The negative ion generator may be disposed in the inner space of the heat sink, the negative electrode brush may be formed so that the front end is exposed to the outside of the light transmission cover, the anion cover is in close contact with the outer surface of the light transmission cover. Can be.

According to the present invention, a frame fastened to a light transmission cover through which light emitted from a light emitting diode passes is formed of a synthetic resin material, and the frame is coated with a metal material having good thermal conductivity, so that the frame is light in weight and has good heat dissipation effect. Can be secured

In addition, the light transmission cover and the frame are commonly formed of a synthetic resin material, but the frame is formed of a synthetic resin material having a higher structural strength than the light transmission cover, thereby ensuring a light weight and a certain degree of structural strength.

In addition, since the light emitting diode illumination lamp includes an anion module that emits negative ions, the comfort of the space in which the illumination lamp is installed can be improved. In particular, the anion brush of the anion module is formed by twisting a plurality of fine metal wires in the longitudinal direction and includes three or more metal fine wires, so that the electro-emission method by the brush can be implemented to release a pureer anion and also time The brush can be effectively prevented from crushing, melting, dust collection, sparking caused by leaked high voltage, shock exposure, ozone generation, and damage to the negative ion generating module.

With reference to the accompanying drawings, a light-emitting diode lamp of a lamp cover integrated according to an embodiment of the present invention will be described in detail below.

1 to 3, a light emitting diode illumination lamp according to an embodiment of the present invention includes a heat sink 10 having a hollow polyhedron shape. For example, as shown in FIG. 3, the heat sink 10 may include a plurality of plate portions having through holes formed in the vertical direction and forming side surfaces thereof.

The heat sink 10 may be formed of a metal material having good thermal conductivity, for example, may be formed of aluminum (Al).

On the other hand, the light emitting diode illumination lamp is provided with a light emitting diode module (20). The light emitting diode module 20 includes a plurality of light emitting diode substrates 21 and a plurality of light emitting diodes 23.

As shown in the figure, the light emitting diode substrate 21 may have a rod shape and is formed to have a predetermined width so that a plurality of light emitting diodes 23 may be installed on the surface thereof. The light emitting diode substrate 21 may include a wiring for selectively applying power to the light emitting diode 23 and may include, for example, a printed circuit board (PCB).

The light emitting diodes 23 may be installed in the light emitting diode substrate 21 along the length direction, and may be arranged in a line along the length direction, for example, as shown in the drawing. The light emitting diodes 23 are provided on the surface of the light emitting diode substrate 21 to emit light to the outside.

As shown in the figure, the light emitting diode substrate 23 is attached to the outer surface 11 of the polyhedral heat sink 10. 1 and 3, the light emitting diode substrate 21 attached to the outer surface 11 of the polyhedral heat sink 10 has an area smaller than that of the outer surface 11 of the heat sink 10. It is formed to have. Accordingly, a part of the outer surface of the heat sink 10 is exposed to the outside without being covered by the light emitting diode substrate 21, thereby increasing the area of the heat sink 10 in contact with the air can increase the heat dissipation effect.

Meanwhile, a polygonal light emitting diode substrate 25 and a plurality of light emitting diodes 27 attached to a surface thereof may be provided at an upper end of the polyhedral heat sink 10. That is, as illustrated in the drawing, the light emitting diode substrate 25 may be attached to the heat sink 10 so as to block the vertical through hole formed by the heat sink 10. As such, since the light emitting diodes 23 and 27 are installed on both the side and the top surface of the heat sink 10, the light propagation range may be increased.

The light transmission cover 30 surrounding the outside of the light emitting diode module 20 is provided. Therefore, the light emitted from the light emitting diodes 23 and 27 passes through the light transmission cover 30 and then proceeds to the outside.

For example, the light transmissive cover 30 may be formed of a transparent or translucent synthetic resin material, and may be formed to condense or diffuse light as necessary.

Frame 40 formed of a synthetic resin material is disposed behind the heat sink 10 and the light emitting diode module 20. The heat sink 10 and the light transmission cover 30 are mounted to the frame 40.

Since the light transmission cover 30 and the heat sink 10 are fastened to and support the structure, the frame 40 made of a synthetic resin material can be used to increase the overall structural strength without significantly increasing the overall weight.

At this time, as shown in the figure, the light transmission cover 30 and the frame 40 have a cup shape (cup) and are fastened so that the open portions face each other. That is, the light transmitting cover 30 and the frame 40 are fastened to each other in a state where the open portion faces downward, and the frame 40 has an open portion facing upward. . Therefore, a space is formed between the light transmission cover 30 and the frame 40, and the heat sink 10 and the light emitting diode module 20 are disposed in the space.

Although not shown in the drawings for the fastening structure of the light transmitting cover 30 and the frame 40 and the fastening structure of the heat sink 10 and the frame 40, they are adhesively bonded or separate fastening members It can be fastened in various ways, such as fastened by. In this case, the protrusion 41 may be formed on the inner surface of the frame 40, and the heat sink 10 may be fastened to the frame 40 while being seated on the protrusion 41.

The light transmission cover 30 and the frame 40 may be commonly formed of a synthetic resin material, and the light transmission cover 30 and the frame 40 may be formed of different kinds of synthetic resin materials.

The frame 40 may be formed of a synthetic resin material having a greater structural strength than the light transmission cover 30. Accordingly, the light transmitting cover 30 is formed of a material having good optical properties even though the structural strength is relatively low, and the frame 40 is formed of a synthetic resin material having a relatively high structural strength, thereby improving the light characteristics of the LED lighting lamp. At the same time, the overall structural strength can be increased by the good structural strength of the frame 40. In addition, since the frame 40 is formed of a synthetic resin material that is relatively lighter than the metal, the frame 40 can reduce the total weight at the same time.

For example, the light transmission cover 30 may be formed of polycarbonate, and the frame 40 may include any one of synthetic resins such as acrylonitrile butadiene styrene (ABS), polyphenylene sulfide (PPS), and polyphthal amide (PPA). It can be formed as one.

Meanwhile, according to the exemplary embodiment of the present invention, the surface of the synthetic resin frame 40 may be coated with a metal having good thermal conductivity. For example, the surface of the frame 40 may be coated with nickel (Ni). Since the frame 40 made of synthetic resin is coated with a metal having good thermal conductivity, heat emitted from the light emitting diodes 23 may be more effectively released through the frame 40. Accordingly, the resin frame 40 may function as a heat sink, and the frame 40 is formed of a synthetic resin material and a metal is coated on the surface thereof, so that a light weight and good heat dissipation function may be obtained.

The protrusion 43 or the groove 45 may be formed on the outer surface of the frame 40. By forming the protrusions 43 and the grooves 45 in the frame 40, the area of the outer surface of the frame 40 is increased to increase the contact area with the outside air, thereby increasing the heat dissipation effect.

A power supply unit 50 for supplying power to the light emitting diodes 23 is provided. For example, the power supply unit 50 may include an electrode 51 connected to an external power source, and may include a switched-mode power supply (SMPS) for supplying power to the light emitting diodes 23. This SMPS is electrically connected to the electrode 51. The electrode 51 applies an external 110V or 220V power source to the SMPS, and the SMPS may convert the applied power source into a constant voltage and electrodeless power source and supply the same to the light emitting diodes 23. Although not clearly shown in the drawing, the electrode 51 and the SMPS, and the SMPS and the light emitting diode 23 are each electrically connected. Since the structure and function of the electrode 51, the SMPS, and the light emitting diode 23 itself are obvious to those skilled in the art, detailed description thereof will be omitted.

As shown in the figure, the power supply unit 50 may be disposed in the space formed by the frame 40 in close contact with the lower end of the heat sink 10. The frame 40 may include a fastening part 47 extending downward, and the electrode 51 may be fastened in a form surrounding the outer circumference of the fastening part 47.

On the other hand, the light emitting diode illumination lamp according to an embodiment of the present invention may be provided with an anion module 60 for emitting anions.

2 to 4, the anion module 60 may include an anion generator 61 and an anion generating brush 63.

The negative ion generator 61 generates negative ions, and the negative ion brush 63 is connected to the negative ion generator 61 and releases negative ions generated by the negative ion generator 61. The negative ion generator 61 may be connected to the above-described power supply to generate negative ions by receiving power, and may be implemented as a negative ion generator known in the art.

The negative ion brush 63 may be formed of a plurality of fine metal wires. In particular, the plurality of fine metal wires may be formed by being twisted in a state intertwined in the longitudinal direction. That is, rather than tying a plurality of metal thin wires to form an anion brush, the metal thin wires anion brush 63 having a longer length are twisted to entangle relatively thin metal wires.

In addition, the plurality of fine metal wires may be formed of three or more kinds of metal materials. For example, the plurality of fine metal wires may be formed of three or more kinds of metal materials such as iron (Fe), nickel (Ni), molybdenum (Mo), and tungsten (W).

Conventional anion generators generally use a corona discharge because the tip portion is composed of one tip or metal wire strand of one or two elemental alloys. Corona discharge refers to a shape in which a high voltage is applied between two electrodes and only a strong portion of the electric field emits light before generating a spark and has conductivity. If both electrodes are flat plates or spheres with large diameters, the electric field is almost uniform, but if one pole or anode is rod-shaped or needle-shaped, the electric field near that pole is particularly strong, resulting in partial discharge. They wake up and emit light or sound. This condition is called corona discharge. When corona discharge occurs, there is a corona loss, and this discharge is in a state where a discharge occurs in a part between poles and is different from an arc discharge in which discharge occurs in all regions between the poles. Corona discharge occurs even at DC low voltage or AC voltage, and the shape of light emitted depends on whether the pointed electrode is positive or negative. In case of AC, positive and negative corona alternates every 1/2 Hz. Corona also appears well in the air. Coronas can also occur in high-voltage transmission lines, causing radio disturbances. This corona method occurs when a portion of the anion brush has one pointed tip shape or a multi-pronged metal tip shape. This corona method generates ozone, causes the brush to clump or melt, and removes dust over time. Collecting dust collection, sparking caused by the leaked high voltage, resulting in shock may eventually cause breakage of the negative ion generating module.

In the present invention, by forming a brush by twisting a plurality of fine metal wires composed of three or more alloys in the longitudinal direction to prevent the corona discharge, which is a problem of the conventional anion generating device, instead of electrospinning by a brush The method can release more pure anions, and also the crushing of the brush over time, melting, dust collection, sparking caused by leaked high voltage, shock exposure, ozone generation, anion generation module It can effectively prevent breakage.

Meanwhile, referring to the drawing, the anion module 60 may include an anion cover 65 to allow the anion emitted from the anion brush 63 to be radiated forward. The anion cover 65 may have a cup shape in which one side is open, and the anion brush 63 is mounted to the anion cover 65 with its tip exposed to the inside of the anion cover 65. . Accordingly, the negative ions emitted from the negative ions brush 63 may be reflected on the inner surface of the negative ions cover 65 to be effectively radiated forward.

The outer circumference of the anion brush 63 may be formed with a coating 64 for the function of insulation and shape maintenance, and the silicon at the portion where the coating 64 of the anion brush 63 contacts the anion cover 65. The member 67 may be provided to reduce the impact between the anion brush 63 and the anion cover 65 and to prevent damage.

According to one embodiment of the invention, as shown in Figure 2, the negative ion generator 61 is disposed in the inner space of the heat sink 10, the negative electrode brush 63 is the front end of the light transmission cover 30 It is formed to extend so as to be exposed, the anion cover 65 is in close contact with the outer surface of the light transmission cover (30). By this structure, negative ions generated and emanated from the negative ion module 60 can be effectively released.

The negative ion generator 61 may be electrically connected to the power supply unit 50 described above to receive electrical energy from the power supply unit 50.

The switch corresponds to the output frequency. The oscillator 73 generates output pulses of a constant frequency, and the booster 74 converts a voltage of a constant frequency output through the controller 72 and the oscillator 73 into a high voltage necessary for generating negative ions (for example, 3 to 12 kV). Step up. The high voltage boosted by the booster 74 passes through the rectifier 75 and is then applied to the negative ion brush 63 through the output electrode 76 to generate negative ions in the negative electrode brush 63.

On the other hand, the anion brush 63 may be coated with silver nano, in which case the silver nano particles are also radiated simultaneously with the anion to further increase the room comfort.
