Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, terms and words used in the present specification and claims are to be construed in accordance with the principles of the present invention, on the basis that the inventor can properly define the concept of a term in order to best explain his invention It should be construed as meaning and concept consistent with the technical idea of.

As shown in FIG. 1, the LED lamp 100 of the present invention includes a base 110 on which the substrate 113 on which the LED 114 is mounted is installed, a cover 120 covering the base 110, and the base. It is characterized in that it comprises a reflective coating layer 130 is applied to (110).

As shown in FIG. 1, the base 110 includes a fixed surface 111 and a reflector 112 forming an inclined gradient at both ends of the fixed surface 111. The base 110 has a front end surface. The upper surface is to have the shape of an open trapezoid.

The fixing surface 111 forms a bottom surface so that the substrate 113 on which the plurality of LEDs 114 are mounted is installed on the upper surface of the fixing surface 111, and the plurality of LEDs 114 on the fixing surface 111 of the base 110. ) Is installed so that the substrate 113 is installed so that the light is transmitted to the entire region of the cover 120 while reducing the number of LEDs 114 installed in association with the reflective coating layer 130 applied to the reflector 112. This allows the viewer to detect surface emission without shading.

To this end, in the present invention, the reflective coating layer 130 is applied to the reflective part 112, and the reflective coating layer 130 is 25 to 100 parts by weight of epoxy resin based on 100 parts by weight of a polyester resin, and a labeling additive. 2 to 10 parts by weight, 2 to 10 parts by weight of the anti-foaming agent, 6 to 30 parts by weight of the photocatalyst and 6 to 30 parts by weight of strontium aluminate, characterized in that it is formed by a composition.

The polyester resin is added as a binder to enhance the reflectance and mechanical strength of visible light, the epoxy resin is added as a curing agent for improving the mechanical properties of the coated reflective coating layer 130. The reason for limiting the content of the epoxy resin as described above is to control the hardness to prevent brittleness.

On the other hand, in the case of powder coating, it is difficult to maintain smoothness because the particles are non-uniform, which is a cause of diffuse reflection. Accordingly, the reflective coating layer 130 may be added to various labeling additives to prevent diffuse reflection and increase the reflectance. For example, an acrylic labeling additive may be included.

The antifoaming agent may include various antifoaming agents, for example, benzoin may be added.

The photocatalyst is a composition in which the reflective coating layer 130 is added to improve the reflectance, it is appropriate that one or a mixture of titanium dioxide, sulfate and barium sulfate is added.

The titanium dioxide is to improve the reflectance by preventing pinholes, etc. formed on the surface of the coating film, the titanium dioxide particles to generate a strong oxygen by the ultraviolet rays contained in the light expressed through the LED to perform a strong redox effect It is possible to prevent the decrease in reflectance due to gas generation by decomposing organic matter and sterilizing.

In the case of sulphate and barium sulphate, high reflectance is shown for wavelength light in the range of 250 nm to 2500 nm, and 1 or a mixture is selectively added to the composition to improve the reflectance.

In particular, the strontium aluminate is added to the reflective coating layer 130, which converts heat generated by the LED 114 into light to perform a heat dissipation function. This is to add additional functions.

Heat generated by the operation of the LED 114 may be moved to another place by heat transfer or to convert the heat energy to other energy to be removed. In the case of heat transfer, the latent heat and heat transfer rate of the heat transfer medium may be affected, and thus may be limited. In the present invention, heat energy is converted into light energy by strontium aluminate included in the reflective coating layer 130. The heat radiation function is to be performed.

When strontium aluminate is exposed to thermal energy, the electrons circulating around the nucleus are excited by the thermal energy, absorbing the thermal energy, and radiating back into the light energy according to the stabilization tendency of the electrons. In other words, the strontium aluminate is to perform a heat radiation function by converting the thermal energy into light energy to radiate.

Referring to FIG. 2, the operational relationship between the reflective coating layer 130 and the reflection of the light E1 generated from the LED 114 serve to remove shadows and at the same time heat energy generated by the operation of the LED 114. By converting (E2) to light energy (E2-1) to perform the heat dissipation function, and also by irradiating the converted light energy (E2-1) to perform the function to remove the shadow.

By this action, the reflective coating layer 130 is to perform a reflection function and a heat radiation function at the same time to form a route to reduce the thermal energy (E2) accumulated between the base 110 and the cover 120.

The reason why the strontium aluminate is limited to the above limited range is to satisfy the cost portion while preventing the degradation such as durability while sufficiently expressing the effects of the above-mentioned heat radiation and reflection function.

On the other hand, when the photocatalyst and strontium aluminate are not uniformly dispersed in the composition of the reflective coating layer 130, shading may occur due to non-uniform reflection, and problems such as thermal deformation may occur due to partial heat radiation. As it is, it is reasonable that 0.5 to 2 parts by weight of propylene carbonate is added to the reflective coating layer 130 in addition to the composition.

As the propylene carbonate is further blended, the photocatalyst and strontium aluminate are uniformly dispersed throughout the reflective coating layer 130 so that light energy E1 and thermal energy E2 by the LED 114 are uniformly reflected. It is possible to control the generation of the shadow, it is possible to control the problems such as partial thermal deformation of the reflective coating layer 130 by converting the thermal energy (E2) to the light energy (E2-1) throughout.

The cover 120 is made of a light-transmissive material to cover the open top of the base 110, but more preferably a reference number is not shown, but the outer frame is formed and the inside of the outer frame diffusion of the light-transmissive material Allow the plate to be constructed. The diffuser plate uniformly diffuses the light projected by the LED 114, which is preferably configured in an embossed shape. The embossing shape is a random uneven shape formed on the surface of the diffusion plate.

The base 110 and the cover 120 may be configured in various shapes, for example, it may be configured in a quadrangular plate shape as shown in Figure 3a, it may be configured in a disk shape as shown in Figure 3b. .

And another embodiment is shown in Figure 4, the LED lamp 100a in Figure 4 is an LED fluorescent lamp.

In the case of the LED lamp 100a of the present embodiment, the base 110a on which the substrate 114 on which the plurality of LEDs 114 are mounted is installed is configured to be the same, and the cover 120a covering the base 110a is the same. However, the LED lamp 100a of the present embodiment is such that the base 110a is made of an aluminum substrate to function as a heat sink. That is, the heat radiating function is made as a material.

At least one rail mounting groove 115 is formed in the base 110a to slide the substrate 113 on which the LED 114 is mounted on the fixing surface 111a. The reflective coating layer 130 is applied to the front surface and the mounting groove 116 is formed on the rear surface is configured to be mounted to the tubular cover (120a) formed with an opening.

4 shows an example in which the rail mounting groove 115 forms an inclined gradient and two are configured. This configuration is intended to broaden the area of light irradiated or reflected by the LED to double the lighting efficiency and to structurally control the shading.

Meanwhile, another embodiment of the present invention is shown in FIG. 5, in which the heat dissipation structure is further added to the substrate 113 and the base 110.

In the present exemplary embodiment, at least one guide hole 113-1 having a diameter narrowed toward the rear surface in contact with the fixing surface 111 is formed on the front surface of the substrate 113 on which the LED 114 is mounted. In the base 110, the diffusion surface 111-1 having a diameter larger than the diameter of the induction hole 113-1 is formed at a position facing the induction hole 113-1 in the fixing surface 111. .

The guide hole 113-1 has a shape in which the diameter is narrower so that the diameter d2 exposed on the rear surface contacting the fixed surface 111 is smaller than the diameter d1 exposed on the front surface on which the LED 114 is mounted. The reason why the induction hole 113-1 is formed through the configuration 113 is that the thermal energy E 2 generated by the operation of the LED 114 is transferred to the heat transfer medium, that is, the fixing surface 111 of the base 110. As described above, this may be affected by the latent heat and the heat transfer rate of the base 110, which is a limitation thereof. In this embodiment, some of the thermal energy E2 is transferred to the induction hole 113. -1) to overcome the limitations of heat dissipation using only the base 110 by discharging to the outside.

In other words, the air heated by the heat energy (E2) is to rise by the convection, it is to discharge some of the heat energy by inducing the rising air to the induction hole (113-1) to be discharged to the outside.

In addition, as shown in FIG. 6, the shape of the induction hole 113-1 is configured to be narrowed upward in the drawing so that air rising to the induction hole 113-1 is formed in the shape of the induction hole 113-1. While being pressurized by air, the speed is increased while the pressure is released in the diffusion hole 111-1 having a large diameter d3, and the air having a higher speed is dispersed quickly.

That is, the air rising by heating is rapidly dissipated to the outside by the structure of the induction hole 113-1 and the diffusion hole 111-1 to increase the heat radiation efficiency of the thermal energy E2-2, and is also illustrated in the drawings. There is no, but to prevent the power supply, etc. mounted on the back of the base 110 to be heated.

By the configuration as described above, in the present invention, the heat energy E2 generated by the LED 114 is partially converted into light energy E2-1, as shown in FIG. 2, and part of the heat energy is induced to induce rising air. Heat energy (E2-2) discharged with air by being discharged to the outside, and part of the heat radiation efficiency by guiding the heat energy (E2-3) transferred to the base 110 through the substrate 113 to double. .

5 and 6 illustrate an example in which the induction hole 113-1 and the diffusion hole 111-1 are further configured in the basic example shown in FIG. 1, but the embodiment is not limited thereto. In this case, it is natural that the induction hole 113-1 and the diffusion hole 111-1 may be configured so that heat radiation is performed to various routes.
