Introduction to LED Panel Lights
LED panel light is an indoor lighting fixture. Its outer frame is made of aluminum alloy by anodizing. The light source is LED. The LED panel light has a unique design. , The illumination uniformity is good, the light is soft, comfortable and bright, which can effectively relieve eye fatigue. The LED panel light is also radiation-proof and will not irritate the skin of pregnant women, the elderly, and children.
Composition of LED panel lights
1) led light source:
Usually the LED lamp beads of LED panel lights use 3528, and some people use 3014 and 5050. The cost of 3014 and 5050 is low, and the light efficiency is slightly worse. The key is that the design of the light guide points is difficult. The LED panel using 3528 lamp beads has high lighting efficiency and good versatility.
2) Panel light aluminum frame:
The aluminum frame of the LED panel light is the main channel for heat dissipation of the LED, and the appearance is simple and elegant. ZY0907 can be used. The mold stamping cost is low, and the processing cost is also low; the IP level of the die-casting aluminum frame of the LED panel light can be higher. The overall appearance is beautiful, but the initial investment in the mold is relatively high.
3) LED light guide plate:
The side LED light is refracted through the dots so that the light is evenly exported from the front, and the light guide plate is the key point of the quality control of the LED panel light. If the dot design is not good, the overall light effect seen will be very poor. Generally, there will be a bright middle and dark sides on both sides, or there will be a bright light band at the incoming light, or a local dark area may be visible, or there will be inconsistent brightness at different angles.
To improve the light efficiency of the light guide plate mainly depends on the design of the dots, followed by the quality of the plate, but there is no need to superstitious the first-line famous brand plate, the light transmittance between qualified plates is usually almost the same. The general small LED lamp factory directly buys the public light guide plate and uses it, so there is no need to re-proof the design. The public version used by many manufacturers is usually of qualified quality.
4) LED diffuser:
The LED diffuser plate can evenly export the light of the LED panel light guide plate, and can also play the role of blurring the dots. The diffuser plate generally uses acrylic 2.0 sheet or PC material. The PS material is almost the same. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC. Acrylic is brittle and has weak anti-aging performance. powerful.
After the LED panel light diffuser is installed, the dots cannot be seen, and the light transmittance should be about 90%. The light transmittance of acrylic is 92%, PC is 88%, and PS is about 80%. You can choose the material of the diffuser according to your needs. Most LED panel light manufacturers use acrylic materials.
5) Drive power:
There are two kinds of LED driving power supply for LED panel light, one is using constant current power supply, this mode has high efficiency, the PF value is as high as 0.95, and the cost performance is high; the other is using constant voltage and constant current power supply, with stable performance, but low efficiency and high cost, Generally, this kind of power supply is mainly used for export. The other party requires certification requirements and must use a power supply with safety regulations. In fact, it is very safe to use a constant current power supply at home, because it is difficult for users to access the power supply, and the LED panel light itself uses a safe low-voltage power supply.
6) Back cover:
The main function is to seal the LED panel light. Generally, 1060 aluminum is used, which can also play a role in heat dissipation.
7) Reflective paper:
Reflect the residual light on the back of the light guide plate to improve the light efficiency, generally RW250.
8) Install the pendant:
The LED panel light is also equipped with suspension wires, mounting brackets and other accessories for installation and fixation.
From the perspective of quality control, it is most effective to spend additional money on LED light sources and LED light guide plates to improve the lighting effect of LED panels. From the perspective of market sales, it is most effective to spend additional money on aluminum frame cover pendants And so on can improve the product grade.
LED panel light application range
LED panel lights are widely used, mainly used in:
1. Ceiling: LED panel lights can be installed on the ceiling instead of the original grille lights;
2. Installation body: Pursue the combination of practicality and art, which is convenient and simple to install;
3. Wall: not only for lighting purposes, LED panel lights also have artistic manifestations, which can be installed on the wall to increase decoration and artistic sense;
4. Others: LED panel lights can also be used in other places, such as train boxes or large mobile cars, counters, etc.
Well, the above is the whole content of LED panel lights brought to you today by LED panel light manufacturer Xinjie. I hope that the introduction of the basic information, components and application scope of LED panel lights can help you better understand LEDs Panel lights, more LED lighting related information will be updated continuously, we will see you in the next issue.
