Generally, conventionally used incandescent lamps, fluorescent lamps, etc. have their advantages and disadvantages, but the energy efficiency is low and the durability is relatively short.

For this reason, recently, lighting lamps using LEDs (LEDs) having excellent energy efficiency and long service durability compared to conventional lighting lamps have been in the spotlight.

Such LED lighting is composed of a reflector coupled to the cover on the front and the LED module installed inside the reflector, a heat sink and a housing.

However, the above-described LED lighting has a problem that the merchandise is deteriorated due to the disadvantage that the heat is very high despite various advantages.

That is, the heat sink structure is increased in order to solve the heat problem of the LED light, and thus, the size of the LED light cannot be compactly configured, and there is a problem that the light efficiency due to the heat problem is also reduced.

In the related art, the heat generation problem of the LED lamp was attempted to be solved by the heat sink structure, but the present inventors tried to solve the heat problem of the LED lamp in the heat sink as well as other elements.

The present invention has been invented to solve all the problems of the prior art, by forming the inner surface of the reflector in an envelope structure to induce the front reflection of both the light wave and the heat wave of the LED module, as well as the heat radiation effect due to the increase in the amount of light The purpose is to maximize the lighting efficiency.

The present invention has a purpose of maximizing the lighting efficiency by increasing the amount of light as well as the heat dissipation effect by forming a cover of the front surface of the reflector to prevent light loss.

The present invention can minimize the size of a separate heat sink structure and LED lighting by improving the heat dissipation and lighting efficiency by improving the cover structure of the reflector and the front surface of the reflector, and the purpose of maximizing the merchandise can be increased durability.

The present invention comprises a reflector coupled to the cover on the front surface and the LED module installed inside the reflector, and the heat sink and the housing, the reflector is enveloped to reflect the light waves and heat waves of the LED module to the front surface on the inner surface It is characterized by its structure.

The envelope structure of the reflector of the present invention is characterized in that y² = 4ax + b (a: reflector diameter, b: focal length, x, y: variable).

The cover is coupled to the front surface of the reflector is characterized in that it is formed of a transparent or semi-transparent flat plate so as to vertically reflect the light and heat waves of the LED module to the front.

The cover of the present invention is characterized in that it forms irregularities for scattering light waves on the outer surface.

The cover of the present invention is characterized in that the plate is a double junction, forming an unevenness for scattering light waves on the inner surface of the plate.

In the present invention, the inner surface of the reflector is formed in an envelope structure to induce the front reflection of both the light waves and the heat waves of the LED module, and the cover of the front surface of the reflector is formed in the form of a flat plate to prevent light loss, so that the heat radiation effect is increased. By maximizing the lighting efficiency, and can minimize the size of the separate heat sink structure and LED lighting, and can increase the durability has the effect of maximizing the commerciality.

3 is a block diagram showing another embodiment of the present invention cover.
Figure 4 is a schematic view showing another embodiment of the cover of the present invention.
Figure 5 is a block diagram showing an embodiment of the applied LED lighting of the present invention.

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

1 to 4, the LED lamp of the present invention comprises a reflector having a cover coupled to its front surface, an LED module installed inside the reflector, and a heat sink and a housing.

The inner surface of the reflector 10 is formed by forming an envelope structure to reflect the light and heat waves of the LED module to the front.

The envelope structure is y 2 = 4ax + b. (a: reflector angle, b: focal length, x, y: variable)

In addition, the cover 15 coupled to the front surface of the reflector 10 is formed by forming a transparent or translucent flat plate 16 to vertically reflect the light and heat waves of the LED module to the front.

In this case, the cover 15 is mainly made of a transparent or translucent material, as shown in Figure 3 can be configured by forming the concave-convex (15a) for the scattering of light waves on the outer surface.

In addition, the cover 15 is configured to double-bond the flat plate 16a (16b) as shown in Figure 4, by forming the concave-convex 17 for scattering light waves on the inner surface of the flat plate 16a (16b) Can be configured.

Hereinafter, the operation and operation of the present invention will be described.

The reflector 10 of the LED lamp of the present invention adopts an envelope structure, i.e., y² = 4ax + b; (a: reflecting aperture angle, b: focal length, x, y: variable) structure, so that the LED module 3 has The generated light waves and heat waves are to be totally reflected by the reflector of the envelope structure.

In other words, by inducing to reflect both the illumination light and the heat generated at this time to the front of the LED module (3) is to maximize the lighting efficiency by the increase in the amount of light as well as the heat radiation effect.

In addition, the cover 15 of the front surface of the reflector is applied in the form of a flat plate 16 rather than a curved surface as in the prior art, when the light wave and the heat wave of the LED module 3 is reflected to the front surface by the reflector, in the cover 15 By preventing the re-reflection to the inside to prevent the loss of light amount and to prevent the internal heat accumulation is to maximize the lighting efficiency by increasing the amount of light as well as the above-mentioned heat radiation effect.

At this time, unlike the conventional method for forming a light wave scattering of the LED module 3 passing through the cover 15, irregularities 15a are formed on the outer surface of the cover or irregularities on the inner surface of the flat plate 16a, 16b which is double bonded. (17) is formed so that the light wave is scattered by the unevenness after passing through the cover, so that even if it is reflected back into the cover by the unevenness, the light passes again through the cover, thereby inducing the scattering effect of the light wave while minimizing internal heat accumulation. Will be done.

In addition, in the embodiment of FIG. 4, since the concave-convex 17 for scattering light waves is formed on the inner surface of the flat plate 16a, 16b, which is double-bonded, dust or foreign matter is caught in the concave-convex structure of the inner and outer surfaces of the cover. The problem of generating light loss is also prevented.

Therefore, the present invention forms the inner surface of the reflector in an envelope structure to induce the front reflection of both the light waves and the heat waves of the LED module and the cover of the front surface of the reflector in the form of a flat plate to prevent light loss, so that the heat dissipation effect as well as the amount of light Maximizing the lighting efficiency by the increase, thereby minimizing the size of the separate heat sink structure and LED lighting, it is possible to increase the durability.
