Description

Light Emitting Diode Lamp Cover {The LED lamp cover}

The present invention relates to a lamp cover for increasing light efficiency or emitting heat generated when a lamp using a light emitting diode (LED) emits light. In more detail, the lamp cover turns on a lamp to emit light. Minimizing the light efficiency reduced by the cover, and has a vent for lowering the temperature inside the light emitting diode lamp cover by discharging the heat generated from the light emitting diode elements to the outside through the vent formed in the lamp cover separately from the heat sink A light emitting diode lamp cover is provided.

In general, lighting fixtures are used to illuminate a dark indoor or outdoor environment. Recently, LED lamps using light emitting diodes, which are environmentally friendly, are used to prevent carbon emissions, which are environmental pollutants.

These LED lamps are eco-friendly products because they do not use environmental pollutants, and they have a long lifespan and save electricity costs. They are applied not only to indoor lights but also to outdoor lights such as street lamps and parks.

However, the problem of the LED lamp has a problem in that the life of the light emitting diode, which is an LED lamp element, is shortened due to the heat generated when the LED lamp emits light.

Therefore, in order to solve this drawback, the method used in the conventional LED lamp to emit heat generated when the light emitting diode emits light to the outside is provided with a heat sink having high thermal conductivity on the upper part of the metal substrate on which the balgo diode device is fixed. To release heat to the outside through the heat sink,

Therefore, LED lamps have a disadvantage that they are larger than general lighting by heat sinks for dissipating heat, and these heat sinks do not directly dissipate heat from the light emitting diode elements, but indirectly dissipate heat. It is difficult to achieve the problem that can not remove the heat generated when the LED lamp emits light.

In addition, the light generated when the light emitting diode emits light has a straightness, so when a person looks directly into the eyes, the glare is worse than that of general lighting, and the Technical Standards Institute, which establishes the standardization of LED lamps, has a cover on the LED lamp. When the LED lamp emits light, the temperature inside the cover of the LED lamp rises and there is no means to emit such high temperature to the outside, which causes a problem of increasing the defective rate of the LED device. The disadvantage is that the temperature difference between the temperature and the cover is increased.

In addition, since the light efficiency of the light emitting diode device is reduced by about 20% due to the cover, there is a problem that the illuminance of light is reduced.

The present invention has been invented to solve the problems caused by indirectly emitting the light efficiency and heat generated by the cover when the conventional LED lamp emits light as described above, and protects the LED device of the LED lamp In order to prevent glare of the light generated by the light emitting diode, the purpose of reducing the temperature by naturally discharging the heat generated inside the cover coupled to the LED lamp to the outside.

In addition, another object of the present invention is to have an additional object of preserving that light generated from the light emitting diode device is reduced in light efficiency by the cover.

As a solution of the present invention for achieving the above object is to form an air vent in the LED lamp cover provided to protect the light emitting diode from the outside and prevent dazzling phenomenon on the front of the LED lamp to open the inside of the cover through the vent opening By allowing the natural release to the outside the present invention can achieve the object.

At this time, it is preferable to form at least two or more vents formed on the cover, and in another embodiment, it is preferable to form at least two or more on the side of the cover.

In addition, the vent is formed by combing instead of forming a right angle with the cover to prevent glare through the air circulation and the vent inside the cover.

Further, the additional object of the present invention can be achieved by forming a protrusion on the front or side of the cover to diffuse light generated from the light emitting diode device.

As described above, the present invention lowers the temperature of the inside of the cover by emitting the internal temperature of the cover of the LED lamp to the outside through the vent to protect the light emitting diode which is the light emitting body when the LED lamp emits light, thereby reducing the size of the heat sink. It is an invention having the effect of reducing the overall size of and the effect of preserving that the cover is reduced light efficiency is made by the light diffusion by the protrusion formed on the cover.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A heat dissipation plate 30 positioned above the fixing plate 20 for dissipating heat generated when the light emitting diode element 21 emits light to the outside;

A power supply unit 40 positioned above the heat sink 30 for stably supplying power to the light emitting diode elements 21 of the fixed plate 20;

A body 10 for fixing the fixing plate 20;

In the LED lamp (1) consisting of a cover 50 which is located below the fixed plate 20 and coupled to the body 10,

At least two or more vents 51 are formed on the side surface 53 of the cover 50 in the longitudinal direction.

As a second embodiment of the vent hole 51 formed in the cover 50, as shown in FIG. 3, at least two vent holes 51 formed in the longitudinal direction at the side surface 53 of the cover 50 are separated from each other. It is formed.

In addition, in the third embodiment of the vent opening 51 formed in the cover 50, at least two vent holes 51 are radially formed on the front surface 52 of the cover 50, as shown in FIG. .

At this time, the ventilation holes 51 shown in the first to third embodiments may be formed as circular holes instead of the long holes in the longitudinal direction.

And, the third embodiment of the present invention shown in Figure 4 is applied to the LED lamp 1, such as (b) or (c) of Figure 1 of the accompanying drawings, the front surface 52 of the cover 50 and A circular vent 51 is formed on the side surface 53, and the vent hole 51 at this time can be formed by combing to have a predetermined inclination angle without being formed at right angles with the front surface 52 or the side 53. will be.

As another embodiment of the cover 50 according to the present invention, at least two or more protrusions 54 in the front surface 52 or the side surface 53 of the cover 50 may be longitudinally or semi-spherical as shown in FIG. 6. It is formed in the shape of, at this time the ventilation opening 51 shown in the first embodiment to the third embodiment is located between the projections (54).

Therefore, the protrusion 54 serves as a convex lens to diffuse light generated from the light emitting diode element 21, thereby preserving that the light efficiency is lowered by the cover 50.

Therefore, the cover 50 of the LED lamp 1 according to the present invention is provided with a vent opening 51 for communicating with the outside air to supply power to the light emitting diode element 21 fixed to the fixing plate 20 through the power supply unit 40. When applied, the light emitting diode element 21 emits light to emit light. At this time, the heat generated when the light emitting diode element 21 emits light is provided on the fixed plate 20 through the metal substrate 22. The temperature of the light emitting diode element 21 is lowered by transferring to the heat sink 30 to radiate heat through the heat sink 30.

In addition, the temperature that is increased inside the cover 50 due to the light emission of the light emitting diode element 21 is caused by the external cold air flowing through the ventilation holes 51 formed in the front surface 52 or the side surface 53 of the cover 50. Natural heat dissipation is made to lower the temperature inside the cover (50).

Therefore, the present invention not only lowers the temperature of the body 10 of the LED lamp 1 but also lowers the temperature of the inside of the cover 50, thereby solving the problem of shortening the lifespan of the light emitting diode element 21 according to the temperature rise. In addition, since the temperature drop can proceed rapidly, the size of the heat dissipation plate 30 can be reduced, and thus the overall size of the LED lamp 1 can be reduced.
