The present invention uses a light diffusing device of a high-brightness LED lamp, more specifically, using a high-brightness LED lamp to transmit light emitted from the LED lamp through a convex lens provided in the diffusion panel when used as a light source of an advertising panel or various lighting fixtures. As the structure expands the range of light irradiation, it expands the range of use of LED lamps that have the characteristics of direct light, thereby producing various advertisements or lighting effects and improving the economic efficiency of use. A light diffuser.

In general, LED devices have been commercialized as lightings by providing white LEDs with the development of blue light emitting diodes along with already developed red and green light emitting diodes, and brightness in the course of rapid development of technology for LED lighting. And with the advent of energy-efficient and long-life products, it is expected to completely replace the bulb in the future.

In the early stages, LED lighting had a low manufacturing cost due to its high manufacturing cost and limited use range, but as technology progressed, its service life became 50-100 times more than existing bulbs. It is widely used.

However, the high-brightness LED has a problem that the side light observed from the side due to the characteristics of the light goes down significantly, so that it is difficult to apply to general lighting or image advertising that can be produced by the diffusion of light, conventionally The technology to diffuse the light of high-brightness LED has a lot of difficulties in commercialization due to the complex appearance of the product and the complicated structure by using means such as reflector or indirect lighting.

The present invention was invented in view of the problems caused when using the conventional high-brightness LED as a light source, the purpose of which is to produce a variety of lighting effects by spreading the light irradiation range with a simple structure and the range of use of the high-brightness LED It is to provide light diffusing device of high brightness LED lamp which can create economic profit by saving power and maintaining maintenance.

The present invention for achieving the above object is to spread the irradiation range of the light emitted from the LED lamp when using the high-brightness LED lamp as a light source of the advertising panel or various luminaires, the high-brightness LED lamp in the form of a bar or circular frame The circuit boards are arranged at regular intervals, and the circuit boards are fixed to the inner wall of the housing of the advertising panel or the luminaire, and each high-brightness LED lamp is accommodated on the outside of the circuit boards to allow light to be diffused to the outside. The diffusion panel of the transparent material lens is arranged, and the connection portion of the diffusion panel connecting each convex lens is formed by forming a lattice-shaped groove to guide the light transmitted through the convex lens, so that the light in a simple structure It is characterized by spreading the irradiation range.

The light diffusing device of the high brightness LED lamp of the present invention can produce a variety of lighting effects by irradiating the light of the LED having a characteristic that the light goes straight with a simple structure, and the power saving and maintenance maintenance by expanding the application range of the high brightness LED There is an economic effect.

Hereinafter, a light diffusing device of a high brightness LED lamp of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing an example of an advertising panel, Figures 2 and 3 is an exploded perspective view of each example of the advertising panel to which the light diffusing device of the high-brightness LED lamp of the present invention is applied, Figure 4 is a cross-sectional configuration of FIG. 5A and 5B are planar views showing one example and another example of a diffusion panel having a convex lens provided in the light diffusing device of the high brightness LED lamp of the present invention, and FIGS. 6A and 6B are high brightness LEDs of the present invention. It is a perspective view which shows each example of the traffic light to which the light diffusing device of the lamp was applied.

The present invention is to spread the irradiation range of the light emitted from the high-brightness LED lamp (L) when used as a light source of the advertising panel (P) or various luminaires using a high-brightness LED lamp, a high-brightness LED lamp for use as a light source ( L) is arranged on the circuit board (PCB) at regular intervals to fix the circuit board to the inner wall of the housing (10) of the advertising panel or luminaire.

The circuit board (PCB) may be manufactured in various forms such as thin and narrow bars or circular frames depending on the form of the advertising panel P or the luminaire.

The diffusion panel 20 of a transparent material having a plurality of convex lenses 21 arranged so that each of the high-brightness LED lamps is accommodated on the outer surface on which the LED lamps L of the circuit board PCB are arranged. ) Is coupled to each other, and the connecting portion 22 of the diffusion panel connecting each of the convex lenses 21 has a lattice-shaped groove 23 having a light guiding function to conduct light passing through the convex lenses.

The convex lens 21 has a configuration in which a rippled curved portion 21 'is formed along the outer circumferential surface of the hemispherical surface starting from the high brightness LED lamp L.

On the other hand, the diffusion panel 20 is formed in a bar shape in which a plurality of convex lenses are arranged at a predetermined interval to cut to the required length, it is preferable to use, but the diffusion panel 20 to form a circular frame It is also possible to form convex lenses at regular intervals (see FIGS. 5A and 5B).

Accordingly, the present invention as described above, according to the shape of the housing 10 constituting the advertising panel (P) fixed a circuit board (PCB) in which a plurality of high-brightness LED lamp (L) is arranged and correspondingly a plurality of convex lenses The high brightness LED lamps L are positioned in the center of the hemispherical surface of the convex lens 21 by combining the diffusion panel 20 of the transparent material having the 21 formed thereon.

Therefore, when the high-brightness LED lamp L is turned on and passes through the convex lens 21, the light that is initially straight goes within a 180 ° range by the bent portion 21 'formed along the outer circumferential surface of the convex lens 21 having a hemispherical surface. In addition, the light guide plate is formed by the lattice-shaped grooves 23 formed in the connecting portions 22 connecting the convex lenses 21 to each other, thereby allowing light to be positioned between the high-brightness LED lamps L. This is conducted to diffuse the light to the entire portion of the advertising panel (P).

Heat generated when the high brightness LED lamp L is turned on is allowed to cool by a plurality of pins formed on the outer wall of the housing 10 to prevent burnout due to heat.

When the circuit board PCB on which the plurality of high-brightness LED lamps L is arranged is in the form of a bar, the diffusion panel 20 is formed in the form of a bar so that a plurality of convex lenses are arranged in correspondence to the diffusion. It is easy to cut or attach the panel, and has various versatility that can be applied to various types of advertising panels and traffic lights that can detect signals from the front and rear as shown in FIGS. 6A and 6B.

In addition, when the circuit board 20 is formed in the shape of a circular frame, the diffusion panel 20 is formed in the shape of a circular frame so as to diffuse the light by the convex lens formed thereon, and thus it may be utilized as a general lighting. .
