It's about.

A lighting fixture illuminates the surrounding space by reflecting, refracting, and transmitting light from a light source. It is used by attaching a ballast inside and supplying power to a fluorescent lamp from the ballast to emit light from the fluorescent lamp.

Lighting fixtures using fluorescent lights not only have the problem of causing fatigue to the user's eyes when used for a long period of time, but are also being replaced by LED lighting fixtures due to high power loss and shortened service life.

A typical conventional LED lighting fixture has a switched-mode power supply (SMPS) installed at the top that supplies power to the LED, and this SMPS is installed on the upper part of the LED lighting fixture with a bolt so that it is covered by an external cover. In addition, the LED lighting fixture has an SMPS installed through the rear cover, an LED module is installed in the lower part of the rear cover, and the front cover is coupled to the rear cover so that the LED module is covered. These LED lighting fixtures are usually installed on the ceiling of a building and used for lighting.

Among LED lighting fixtures, flat LED lighting fixtures are made up of a PCB board on which the LED module is mounted, a diffusion plate that diffuses the LED light source, and a cover on the upper side. The PCB board, diffusion plate, and cover form a structure that is mounted on the frame that forms the enclosure. .

On the other hand, lighting fixtures using conventional LEDs have LED modules inside an integrated frame and are inserted into walls, ceilings, etc., so when the LED module reaches the end of its lifespan and is replaced, the entire lighting fixture must be dismantled from the wall, ceiling, etc., causing the inconvenience of having to replace it. There is a problem that maintenance costs increase due to disassembly and assembly not being easy.

As video technology advances from SD to HD and back to UHD, the performance of cameras is becoming more and more high-end. Accordingly, not only is a greater amount of light required from cameras, but uniformity of light is becoming important.

The present invention can supply a large amount of uniform light to the camera by uniformly installing the above-described LED lighting fixtures at the top of a UHD studio. The structure for installing LED lighting of the present invention can replace the complex and dangerous lighting fixtures currently used in broadcasting studios. In addition, in the past, the lighting had to be moved or the irradiation angle adjusted according to the movement of the person, but according to the present invention, the amount of light is abundant and uniform in the space where the LED lighting fixture is installed, so the person can move freely, and the illuminator can be adjusted according to the situation. Since there is no inconvenience in setting up, you can dramatically save money and time.

However, conventionally, illuminators are installed one by one on a pipe grid or electric batten, and at this time, the irradiation direction of light is installed so that it is downward, so a certain illuminance uniformity is satisfied on the floor where the light is ultimately reflected, but when light is irradiated on a person, the upper body is irradiated.
