The rear cover plate of the panel light is used to seal the lamp body. The main material is aluminum, so there is also a little heat dissipation. effect.
LED panel light size specifications
The more common LED panel light sizes are 600*1200mm, 300*1200mm, 600*600mm, 300*300mm, etc. The number of LED panel lights of different sizes is different, and the luminous flux is also different .
The difference between a panel light and a flat light
Generally speaking, there is no difference between a flat light and a panel light, but because the LED panel light looks like a flat panel, it is called an LED flat light in some places. Both refer to the same thing.
The difference between panel light and down light
1. Different power
The general power of panel light is larger than that of down light, most panel lights The power of the lamp is basically above 8w, while the power of the downlight can be as low as 3w.
2. Different applicable occasions
Panel lights are mainly used for kitchen and bathroom decoration, while low-wattage downlights are mainly used for home living room decoration.
The difference between panel lights and ceiling lights
1. Different prices
The price of ceiling lights is lower than that of panel lights, and the price of general LED ceiling lights is less than 100 yuan , and the average price of panel lights is basically more than 100 yuan.
2. Different uses
LED ceiling lights are mostly used in home, corridor and aisle, while panel lights are mostly used for business Lighting, office lighting use.
What are the different styles and models of the panel lights?
According to the style of the panel lights, it can be divided into flat panel lights, embedded panel lights, ceiling panel lights, hanging Type panel lights, round panel downlights, round ceiling lights and other types.
Lighting mode distinction
According to the light-emitting mode of the panel light, the panel light can be divided into two types: direct-lit panel light and side-emitting panel light. The side-emitting panel light is light and thin, but the light emission is easy to be uneven. The direct-lit panel light has sufficient brightness, but glare is unavoidable.
Power distinction
The rated power of common panel lights on the market are 60W, 26W, 19W and 9W.
How to choose the panel light to see the light color
The light color of the panel light is very important, it will directly affect the use experience. There are two types of common panel lights: yellow light and white light. When choosing a yellow light panel light, be careful not to turn reddish, while the white light panel light should not turn blue or green, otherwise it will damage your eyesight. In addition, the entire lamp should emit evenly, and there should be no dark areas.
Look at the material
The main material of the panel light frame and back cover is aluminum. When choosing, you can try to choose a thicker bottom plate. At the same time, you can compare the average area of the aluminum substrate on the back of each LED. The larger the heat dissipation, the better the quality.
Price and brand
When choosing panel lights, you can also start from the perspective of price and brand. Generally speaking, cheap products are definitely not good ones. Don’t be greedy to buy low-quality panel lights cheaply, which will be harmful to your eyes. harmful. You can choose a well-known panel light brand, and the quality will be relatively guaranteed.
How to install panel lights Recessed installation
The method of recessed installation of panel lights is mostly used in offices, shops, kitchens and bathrooms, etc. , and the most common installation method. When installing, first remove a piece of the ceiling, then put the power driver of the panel light on the ceiling next to it, and finally connect the power cord and install the panel light spring clip.
Ceiling-mounted installation
The method of ceiling-mounted installation of panel lights is more personalized and suitable for use in the home environment with modern decoration. When installing the panel light in the ceiling type, you first need to hang the panel light on the ceiling with a hanging wire, then connect the driving power cord of the light, and pull the steel wire to adjust the height of the panel light.
Inlaid installation
Inlaid installation of panel lights can be divided into two ways, one is concealed installation, that is, the outer frame of the panel light is inlaid inside the ceiling, which is more suitable for simple decoration, and the other is It is a surface-mounted type, in which the outer frame of the panel light is inlaid on the outside of the ceiling, and then the panel light is fixed in the frame.
How to remove the panel light
The disassembly method of the square panel light is very simple, just push up and let go, the panel light will be automatically removed; the round panel light needs to be pulled down hard, and then the panel light spring The clips can be disassembled one by one; the hanging panel light can be directly unfastened the panel light and the hanging wire; the embedded panel light needs to use the suction cup to buckle the panel light plate, and then it can be smooth. dismantled.
How to fix if the LED panel light is broken? What should I do if the panel light is flickering? Check for another drive. If the panel light in the bathroom or kitchen is flickering, it may be due to water ingress, then the lamp beads and light source need to be replaced.
How to fix if the LED panel light does not light up? There are generally two reasons why the LED panel light does not light up. One is that the leakage current is too large, and the other is that the internal connection leads of the LED panel light are disconnected. If the leakage current is too large, you can replace the chip of the LED panel light. If the internal connection lead is disconnected, you need to replace the internal connection lead, or use electrical tape to connect the disconnected parts.
What should I do if the panel light turns yellow?
If yellowing occurs on the surface of the light guide plate, it is probably because the light guide plate is burnt, and the light guide plate needs to be replaced; if the yellowing position is near the gate, it may be because the stains attached to the light guide plate have penetrated into the guide plate. The light guide plate can be removed and wiped; if the yellowing position is at the corner of the light guide plate and the position is fixed, it may be caused by the material change of the light guide plate itself. In this case, the light guide plate needs to be replaced.
What should I do if the panel light is dimmed
The panel light is dimmed mostly because the driving power supply is not working, resulting in a lower output current. Generally, it is recommended to replace the whole light in this case. However, it is also possible that the drive output current does not match the current that the panel light can withstand due to the mismatch between the panel light and the driving power supply. At this time, it is only necessary to replace a driving power supply that matches the power of the panel light.
