LED light using high brightness reflector {LED Light Using High-Luminance Reflector}

The present invention relates to an LED using a high brightness reflector.

In general, various types of lamps or the like are used to identify objects at night or in a dark room. Until now, lighting lamps have mainly used metals, sodium lamps, and mercury lamps as light sources, but the energy consumption is very high compared to the brightness of the lamps, and the lifespan is short. There are disadvantages.

In addition, the conventional lighting has a problem that acts as a cause of environmental pollution during disposal, since the mercury gas is mainly embedded therein.

In order to solve such a problem, a lot of researches are being conducted as a next-generation lighting that has excellent light efficiency compared to other light sources, saves energy, and uses an eco-friendly LED.

However, LED lighting is difficult to maintain uniformity of illumination, it is difficult to control the back light and has the disadvantage of low illumination compared to the conventional PL fluorescent lamp.

In order to solve the above problems, although the reflective plate of aluminum material is used, there are still many problems such as a lot of heat generation and a short circuit.

The present invention has been made to solve the above problems, and there is no fear of a short circuit, and an object thereof is to provide an LED with improved illuminance.

LED and the like for irradiating light according to the present invention to achieve the above object is a socket connected to electricity; A circuit board having a bar heat dissipation hole connected to the socket; A plurality of LED elements arranged on the circuit board to irradiate light; A diffusion cover having an open end and an elliptical cross section, the diffusion cover of which spreads the irradiation range of light by wrapping the circuit board on which the LED elements are arranged; And a high brightness reflector plate of a non-conductor material bonded to the circuit board on which the plurality of LED elements are arranged, the hole being formed to match the heat dissipation hole formed on the circuit board and the plurality of LED elements arranged on the circuit board. And a control unit.

The material of the high brightness reflector is characterized in that the polyethylene terephthalate (PET).

The LED of the present invention has no fear of leakage due to the use of a high-brightness reflector of non-conductor material, and has better light efficiency and improved illuminance than conventional LEDs.

2 is an exploded rear perspective view of the LED according to the embodiment of the present invention.
3 is a perspective view of the coupling according to the embodiment of the present invention.

Exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings, but the well-known technical parts will be omitted or compressed for brevity of description.

1 is an exploded perspective view of the LED light according to an embodiment of the present invention, Figure 2 is an exploded rear perspective view of the LED light according to an embodiment of the present invention, Figure 3 is a combined perspective view according to an embodiment of the present invention.

As shown in FIG. 1, an LED according to an embodiment of the present invention includes a socket 100 connected to electricity, a bar-shaped circuit board 200 connected to the socket 100, and a circuit board 200. A high brightness reflecting plate 500 bonded to a plurality of LED elements 300 to be irradiated with light, a diffusion cover 400 surrounding the circuit board 200, a plurality of LED elements 300 is bonded to the circuit board 200 is arranged And a housing 600 that blocks one opening of the diffusion cover 400.

The circuit board 200 has a flat bar-shaped top plate and a side surface having a convex oval shape, and a central portion of the circuit board 200 is formed of a flat bottom plate and a bottom plate including grooves to be fitted with the diffusion cover 400. Moreover, the some hole is formed in the center part of the lower board.

In one embodiment, the LED elements 300 are arranged in two columns in the longitudinal direction on the circuit board 200 and are irradiated with light by receiving electricity from the circuit board 200.

The diffusion cover 400 is open at both ends and has an elliptical cross section so as to surround the circuit board 200 on which the LED elements 300 are arranged from the outside so that the irradiation range of light is diffused, as shown in FIG. 2. The diffusion cover 400 is fitted through a groove formed in the rear surface of the circuit board 200 and is coupled to the circuit board 200 by pushing in a slide manner.

As shown in FIG. 3, a socket 100 is connected to one opening of the diffusion cover 400 and a housing 600 is connected to the other opening to block openings at both ends of the diffusion cover 400.

The high brightness reflecting plate 500 may be bonded to the circuit board 200 on which the plurality of LED elements 300 are arranged and may be a ketone-based adhesive that is heat resistant as an embodiment. In addition, the high brightness reflector 500 includes a heat dissipation hole 510 and an LED hole 520. The LED hole 520 coincides with the LED element 300 arranged on the circuit board 200, and the heat dissipation hole 510 coincides with the heat dissipation hole 210.

The LED hole 520 is necessary for the LED element 300 arranged on the circuit board 200 to be exposed outward, and the heat dissipation hole 510 is required for dissipating heat generated during lighting.

In addition, the socket 100 includes a terminal 110 to be electrically connected to a mechanism to which electricity is connected, for example, a stand, a light module, a PL lamp, and the like.

The bar-shaped circuit board 200 connected to the socket 100 is a printed circuit board (PCB) board in one embodiment, and the socket 100 is electrically connected to a mechanism through which the socket 100 is electrically connected. When connected to the circuit board 200 receives electricity from the outside serves to supply electricity to the LED element (300). In addition, it includes a heat dissipation hole 210 to release heat.

When the LED device 300 is supplied with electricity and irradiates light, the diffusion cover 400 helps to irradiate the irradiated light evenly to the outside. In addition, the irradiated light may return to the circuit board 200 after hitting the diffusion cover 400.

Illumination is improved by adhering the high brightness reflector plate 500 onto the circuit board 200 to diffuse the reflected light as described above. According to the following [Table 1], when the high brightness reflecting plate 500 is used, the illuminance is improved by 17.6% at 1m distance, 46.7% at 1.5m distance, and 17.3% at 2m distance than LEDs without using the conventional reflecting plate. . Although the aluminum reflector is used to improve the illuminance, the aluminum reflector is a conductor, and therefore, a short circuit may occur at the contact point between the circuit of the circuit board and the LED element. High brightness reflector plate 500 used in the present invention is characterized in that the material is a non-conductor, for example polyethylene terephthalate (PET). Therefore, the light efficiency is good and the illuminance is improved while there is no fear of leakage.

In addition, the transparent cover may be used to improve the illuminance as shown in [Table 1], but the glare is difficult to use as a product. Therefore, it is preferable to use a diffusion cover according to an embodiment of the present invention.
