The present invention relates to a lens-attached LED module, in particular, by forming a wide-angle lens for diffusing the LED light on the cover case covering the LED around the waterproof, to improve the assembly productivity by simplifying the waterproof and diffusion structure of the LED It is for.

In general, indoor or outdoor advertisements or signs are made of a light emitting structure using neon signs or LEDs using neon gas, or Panaflex advertising by putting fluorescent lights on the back of the actual graphics for easy recognition at night. The form is used.

Here, in the case of advertisements using neon signs, the brightness is high, so it is easy to visually identify, but the neon tube is exposed, so it is easy to be damaged, it is difficult to clean the water, and high power is consumed because high voltage is used. It is inefficient.

Due to this inefficient problem, a billboard is usually used by using an LED, and the billboard using the LED is disclosed in Korean Patent Application No. 10-2000-49978 (indoor / outdoor advertising method). It is disclosed in Korean Utility Model Registration No. 20-178982 (light emitting structure using synthetic resin and light emitting diode) as a surface emitting display panel using a light emitting diode.

1 and 2 is a cross-sectional perspective view of a light emitting structure using a conventional LED according to the prior art, the light emitting structure 5 shown in FIG. 1 is an LED 10, a reflective layer 20, a resin filler 30 ), A light transmission window 40, an outer frame 50. The reflective layer 20, the LED 10, the resin filler 30, and the like are sequentially installed in the outer frame 50, and the transparent layer 40 is covered on the top. The outer surface of the light transmission window 40 forms a light emitting surface 51.

2 is a cross-sectional perspective view of a light emitting structure using a chip-type LED, and includes a chip-type LED 60, a reflective layer 20, a resin filler 30, and an outer shell 50. The reflective layer 20, the chip-shaped light emitting device 10, the resin filler 30, etc. are installed in order in the outer frame 50, and the upper layer of the resin filler 30 is mixed with fluorescent materials or phosphors. The configured fluorescent layer 35 is formed. The upper surface of the resin filler 30 forms a light emitting surface 51 that emits light among the outer portions of the outer frame 50.

Here, unlike the general LED 10, the chip-shaped LED 60 is connected to the connection terminal 11, the light emitting wiring 12, etc. separately, the LED 61 is soldered on a flat PCB (Printed Circuit Board) 62, etc. It is attached by the method of form.

Employing such a chip-shaped LED 60 has the advantage that the thickness of the light emitting structure 6 can be reduced. The reflective layer 20 and the resin filler 30 are the same as those of FIG. 1, and the fluorescent layer 35 emits light emitted from the LED 61 in various colors, thereby enhancing the light emitting effect of the light emitting surface 51. . The structure of the outer frame 50 except for the light emitting surface 51 is the same as the structure of FIG.

Such a light diverging structure according to the prior art uses a predetermined urethane paint on the bottom and both sides of the outer frame to make a reflection plate to give a brighter light to the surface, and scattered light by filling the transparent epoxy on both sides and the surface The effect of surface light emission is obtained.

However, such a light emitting structure according to the prior art has a problem that must be subjected to a complicated process of filling the transparent epoxy in the reflecting plate and both walls in the outer frame.

In addition, in the case of the advertisement display panel manufactured according to the prior art, even if the wide angle of light emission is narrow due to the nature of the LED or chip-type LED used, the focus of LED light emission is visually recognized, and a plurality of LEDs or chip-type LEDs are used. There was a problem that the brightness of the surface is uneven when manufacturing the advertising display panel. In order to overcome this problem, when a large number of LEDs or chip-type LEDs are installed, manufacturing costs increase.

The present invention has been made to solve the above problems, an object of the present invention is to form a wide-angle lens for diffusing the LED light in the cover case to cover the LED around the waterproof, to provide a waterproof and diffusion structure of the LED In order to simplify assembly productivity.

In the present invention for achieving the above object, in the LED module comprising an LED, and a casing containing the LED,

Fixing a wide-angle lens for diffusing light emitted from the LED to a wide angle, and provides a lens-attached LED module, characterized in that the cover case for protecting the inside of the casing is fixed to the casing.

Contact portions of the cover case and the casing are sealed to maintain watertightness.

Hereinafter, a preferred embodiment of the lens-mounted LED module of the present invention will be described with the accompanying drawings.

In the LED module illustrated in this figure, the substrate 110 is fixed inside the casing 100, and a plurality of LEDs 120 are connected to the substrate 110. Then, the power supply wire 150 enters from the side of the casing 100 and is connected to the substrate 110, and then is drawn out to the opposite side to be connected to another LED module.

The cover case 130 is fixed to the wide-angle lens 140 to diffuse the light emitted from the LED 120 to a wide angle, and is made of a material that transmits the light emitted from the LED (120).

The cover case 130 is fixed to the casing 100, and the contact portion between the cover case 130 and the casing 100 is coated with silicone to seal and waterproof.

As such, when the cover case 130 is sealed to the casing 100, external moisture does not penetrate into the LED 120 and the substrate 110, and thus a structure waterproofing with epoxy or silicon may be omitted. .

Hereinafter will be described the operation of the present embodiment as described above.

The light emitted from the LED 120 passes through the wide-angle lens 140 and the directivity angle is diffused. Therefore, it is possible to illuminate a large area at a low height from the LED (120).

And the remaining light emitted from the LED 120 does not pass through the wide-angle lens 140 is emitted to the outside through the cover case 130.

Meanwhile, since the cover case 130 is sealed to the casing 100 and moisture does not penetrate into the casing 100, the substrate 110 and the LED 120 are protected from the risk of shorting.

As described above, the present invention forms a wide-angle lens for diffusing the LED light in a cover case covering the LED to be waterproof, thereby simplifying the LED's waterproof and diffusion structure, thereby improving assembly productivity. have.

The present invention has been described above by way of specific embodiments, but the present invention is not limited to the above-described embodiments, and those skilled in the art without departing from the gist of the present invention claimed in the claims. Anyone can make a variety of variations.
