It is important for everyone to know the materials for LED panel light, which are basic requirements to know how to choose a high-quality product.
Frame(shell). The original LED panel light solutions are only with a 6063 aluminum frame. It is usually anodized, the surface is very flat, and the conventional color is silver. Usually, many customers on the market will need a white frame. The black frame can also be customized, but often the price will be higher than the other two colors. and the frame thickness is 8-12mm.
Light Guide plate and diffuser plate. The quality of the light guide plate is one of the most important factors to determine the quality of LED flat panel light. The use of a high-quality light guide plate can make the finished light panel emit more evenly. There will be no dark spots, water ripples, etc. The light guide plate on the market is mainly divided into three categories: laser dot light guide plate, ink printing light guide plate, and structured light guide plate. The difference between price and quality is the laser dot light guide plate > ink light guide plate > structure light guide plate. The bad quality LGP will make the LED panel light turn yellow. And the thickness of the light guide plate is 1.0mm,1.2mm,1.5mm,2.0mm, and 3.0mm. The diffuser plate is made of PS materials, with a thickness of 1.0mm 1.2mm, or 1.5mm, optionally thicker; the more expensive the price, the better the effect. Under the condition of budget permission, the light guide plate with a laser point shall be selected as far as possible. On the market, prone to yellowing panel lights are generally used with the structure of the light guide plate. Our ultra-thin LED panel lights never use a structured light guide plate. Some special light Guide plates are Anti-glare, which is a key material for anti-glare LED panel lights with UGR<19.
LED chips on PCB.PCB is an aluminum material with a copper circuit. and the LED chips generally are SMD2835, SMD4014, SMD5630. Most of the LED ceiling light panel is with 2835SMD chips, and SMD5630 chips are popular if customers request higher lumens output. These LED chips’ price is also much different from those of different manufacturers. We just use high-quality LED chips from Epistar. Stable performance, good brightness, small light attenuation, and good color rendering index.
The reflective paper, which is only used on the side of the light-emitting panel lamp, is used to reflect light and increase light efficiency.
Backplate. For a slim LED panel light, the backplate is a thin iron plate; it is also ok to do an aluminum plate for it if requested. For a backlit panel LED light, the backplate and lamp body are integrated; generally, it is iron materials.
LED driver. For an LED office panel light. It is the key to the quality of LED ceiling panel lights. The quality issues for LED lamps lead to driver issues. There are many cheap LED panel lights in markets; they are generally with Non-isolated drivers, it is simple and easy to blink or burn. We only use high quality&famous brand-led drivers for our LED panel light, like DONE, LiFud, Meanwell, GS, Boke, and Eaglerise, which are all up to 50000Hrs lifetime and free flicker, it is very suitable for different commercial projects. We have used these brand drivers for 5 years, and the fault rate is very low, about 0.3% within 5 years.
There are mainly 4different installation types for LED ceiling panel lighting as follows
- Recessed LED panel lights
This installation method is often used in offices, shops, kitchens, bathrooms, etc. It is also the most common installation method. First, remove a ceiling, put the LED panel light driver on the ceiling next to it, then connect the power cord, and then put it on Panel lights are sufficient, and the installation method is relatively simple.
2. Suspension flat panel led light
You need to prepare a set of steel ropes first. Hang the lighting from the ceiling with steel ropes. First, fix the 4 hanging wire bases on the lighting fixture on the roof, then tie the 4 hanging wires to the LED panel light, connect the light’s driving power cord, and pull the wire to adjust the height of the panel light. The installation method is more flexible
3. Surface-mounted LED panel light
Use screws to fix 3 sides of the frame onto the proof. Then connect the LED driver, insert the LED light panels into frames, and finally, screws the last frame.
4. Clip installation
Generally, these are clip-led ceiling panel lights, it looks like recessed LED downlights. Then the installation way is the same.
There are a variety of different dimensions for ceiling panel lights in markets, some standard, like 600x600mm, but someone is the non-standard sizes, which can be customized. Different dimension is also available with some power consumption options as follows:
Small round LED panel light. This type looks like slim LED downlights, generally, from 2 inches to 10 inches, the power is 5W, 7W, 9W, 12W, 15W, 18W, 24W, 30W.
Big square led flat panel lights, mainly include 600x600mm, which is 595*595mm in actual size, and with 40W. This is the most popular in markets. What is more, for some special markets, like Germany, there is a 620x620mm type instead of 600x600mm.
Rectangle led Panel lights. This type is with 1200x300mm 40W,1200x600mm 60W troffer light. Of course, the power consumption generally can be customized according to the customer’s requirement, for example, sometimes, an LED panel light 2×2 can be with 60 watts max.
Like all LED lamps, the color temperature choice of panel lights also includes warm light, natural light, and cool white light. The use of lamps is closely related to our life and work. Different color temperatures often have different effects on us
♦. In places with low illumination requirements, low color temperature light makes people feel comfortable; high color temperature makes people feel cold; high illumination needs places, low color temperature light makes people feel stuffy; in high illumination needs places, high color temperature light makes people feel comfortable and happy.
♦. The workplace needs a high-illuminance and high-color temperature environment, and the resting place needs a low-illuminance and low-color temperature environment.
Like a thermal processing workshop, the use of cold light sources can make people feel cool, psychologically suggest, and relieve irritability, thereby improving the safety and pass rate of production.
♦. People in different climates and different cultures have different preferences for light and color. Most people in tropical and subtropical climates prefer white light or daylight, while people in cold regions mostly like warm light sources with low color temperatures.
3000-3200K warm white is good for the living room. 4000-4500k natural white is better for offices,6000-6500K is suitable for workshops, which makes people awake
