Description

LED luminaire with built-in cortex pad {LED load lighter}

Typically, luminaires are installed on sidewalks or on roads to perform functions that make the safety and human traffic of vehicles running at night more convenient. Such a luminaire is mainly used a variety of light sources such as incandescent lamp, high pressure mercury lamp, fluorescent lamp, sodium lamp. However, although incandescent bulbs have a disadvantage in that more heat is generated than light, their use is gradually being reduced even though they can be manufactured inexpensively. Fluorescent lamps have the advantage of saving energy because they convert electrical energy to light energy more than incandescent bulbs, but they have a limit of long lighting time and short lifespan. In addition, as a single light source is installed in the luminaire, when the life of the light source expires or the operation is stopped due to a failure or the like, there is a problem of causing inconvenience to pedestrians and vehicles until the light source is replaced. In addition, a lot of heat is emitted from the light source, in the case of a conventional luminaire there is a problem that the cover covering the light source melts or breaks due to heat is not provided to the outside.

Luminaires using LEDs (Light emitting diodes), which can achieve high illuminance with a low power and greatly extend their service life, are being actively researched and developed. As a light emitting device that changes in size, it has a small volume, low power consumption, and has a relatively long lifespan compared to other lighting devices due to its low heat dissipation characteristics. It is widely used for lighting, internal equipment, and electronic display boards.

Conventional LED lighting supplies power to a strut of a predetermined height, an LED luminaire body installed on an upper part of the stool, a plurality of LED lamps formed inside the LED luminaire body, a fixing portion connecting the strut to the LED luminaire body, and an LED lamp. It consists of a glove to protect the converter and the LED lamp. The glove is usually manufactured in a concave shape using transparent glass or acrylic as a device for protecting the LED lamp. In addition, due to the low thermal conductivity of the transparent or acrylic constituting the glove, there is a problem in that heat emitted from the LED lamp is not easily dissipated, thereby shortening the life of the LED luminaire.

An object of the present invention for solving the conventional problems as described above is to provide an LED luminaire for improving the heat dissipation effect that can solve the problem that the lighting effect is inhibited due to various external pollution factors. Another object of the present invention is to provide an LED luminaire for improving the heat dissipation effect that can solve the problem that the maintenance cost increases due to various external pollution factors. Another object of the present invention is to provide an LED lamp for improving the heat dissipation effect to further extend the life of the LED lamp.

The present invention is equipped with a side cover on the upper surface and the lower surface of the LED lamp body 100 and the Cortex pad 80 between the upper and lower surfaces and the side cover (70-1, 70'-1) of the lamp body (100) , 80 ') is built in.

The present invention is a Cortex pad is built between the upper and lower surfaces and the side cover of the LED luminaire main body is not provided with a separate glove to protect the LED lamp, the thermal effect of the Cortex pad material excellent in thermal conductivity of the LED lamp is hindered The conventional problem can be solved neatly, and the maintenance cost for removing the contaminants of the globe can be reduced, and excellent heat dissipation effect can be expected without a separate cooling device, thereby improving the life of the LED luminaire. It can be extended.

The present invention is installed on the top of the street lamp post, the LED luminaire body 100 is formed with an air circulation through-hole 102 so that air can be circulated from the bottom to the upper direction; An LED module 10 embedded in the LED luminaire body 100; A front cover 60 mounted with a lens 20, a reflector 30, a protective cover 40 and a waterproof protective rubber 50 on the front surface of the LED module 10 and mounted on the front of the waterproof protective rubber 50; And a cortex pad between the upper and lower surfaces of the luminaire body 100 and the side covers 70-1 and 70 ′-1 in the LED luminaire including the side covers mounted on the upper and lower surfaces of the LED luminaire body 100. It relates to an LED luminaire with a cortex pad, characterized in that the (80, 80 ') is built.

In the LED luminaire having the cortex pad of the present invention, the air circulation through-hole 72 is formed at the center of the side covers 70-1 and 70'-1, and the side covers 70-1 and 70'-1 are formed. Heat dissipation through holes (74, 74 ') are formed on both sides of the air circulation through hole (72), and the air circulation through hole (82) is formed at the center of the cortex pad (80, 80'). It is done.

The LED luminaire with the cortex pad of the present invention is equipped with side covers on the upper and lower surfaces of the LED luminaire main body 100, and the upper and lower surfaces and the side covers 70-1 and 70 'of the luminaire main body 100. Cortex pads 80 and 80 'are built in between -1). In the LED luminaire of the present invention, the air circulation through hole 72 is formed at the center of the side covers 70-1 and 70'-1, and the air circulation through hole of the side covers 70-1 and 70'-1 is formed. (72) Heat dissipation through holes 74 and 74 'are formed at both sides, and air circulation through holes 82 are formed at the center of the cortex pads 80 and 80'.

The LED luminaire with the cortex pad of the present invention is a technique for applying a lens used for light distribution of the LED luminaire to the luminaire and an air circulation structure for heat dissipation. Heat generated from the LED in the LED luminaire of the present invention is transferred to a heat sink for heat dissipation of the luminaire through the PCB substrate. In this structure, the remaining heat in addition to the heat emitted to the outside is present inside the luminaire, which causes the heat rise of the LED. The most commonly used structure for heat dissipation is heat sink or heat sink structure. When time passes, dust and debris accumulate between the slots of the heat sink. You lose it. In order to solve the above problem, the LED luminaire of the present invention has a structure that enables air circulation in the side cover to circulate heat not emitted from the luminaire. The LED luminaire of the present invention uses a material such as Gore-tex on the side cover to apply a material that blocks water and allows air to pass through, and solves the waterproof problem and at the same time smoothes the air flow to dissipate the luminaire. To help. LED luminaire of the present invention can be applied to the heat sink (slot) structure for heat dissipation in the luminaire is improved heat dissipation effect of the luminaire.
