At present, the LED panel lamp power supply is widely used in various fields, about the LED panel lamp power is what are the material composition, are interested I believe you know, after all, and we should pay attention to what matters, in use is associated, in order to let everybody can reasonably use LED panel lamp power supply in the future, take you to get to know what are the materials of LED panel light power? Of LED panel light power: a, LED light guide plate, the side LED light refraction by branch make the light even derived from the front, is LED panel light quality control key points of light guide plate. General will appear on both sides of the middle bright dark, or into the light with the light take, or visible partial dark space, brightness inconsistent again or a different Angle. To improve the photosynthetic efficiency of light guide plate depend mainly on the design of the network, the second is the quality of the plate, but it is not necessary to superstition first-line brand of plank, qualified plate between the light transmittance, usually don't need to proofing design, more manufacturers use the male version usually quality qualification. Second, the panel light aluminum frame, is the main channel of the LED heat dissipation, appearance is simple and easy, can use ZY0907, USES the low cost of die stamping mould, machining cost is low; Die-casting aluminum frame IP rating can be a little higher, the surface texture is good, the whole is beautiful, but early into the mold cost is higher. Three, the LED light source: usually use 3528 LED lamp bead, also somebody USES 3014 and 5050. 3014 and 5050, the cost is low, slightly less, the key is the light dot design difficulty. 3528 bright dot good commonality. Fourth, the drive power supply, there are 2 kinds of LED drive power supply, one is to use a constant current power supply, the model of high efficiency, PF value up to 0. 95, cost-effective. The second is the use of constant pressure constant current power supply, stable performance, but low efficiency, high cost, the use of the general power supply is mainly exports, the other requires certification requirements, shall be used for safety of power supply. Actually family use constant current power supply is very safe, because users are hard to come into contact with the power supply, and the lamp body is safe to use by itself, low-voltage electrical. Five, LED diffuser plate: light guide plate export evenly and can also play a role of fuzzy network. General use acrylic diffuser 2. 0 plate or PC material, almost is PS material, acrylic lower cost and light transmittance is higher than the PC is a bit high, acrylic brittle anti-aging performance is weak, the PC price a little expensive, but strong anti-aging performance. Diffuser in mount later can't see the site, and light transmittance to around 90%. Acrylic light transmittance at 92%, the PC was 88%, the PS is probably 80%, we can according to the requirements in terms of diffusion plate material choice, most manufacturers are using acrylic material at present. Reflective paper: will guide plate on the back of the corner reflection out in order to improve the light efficiency, for RW250 commonly. HouGaiBan: the main function is to seal the LED panel lights, generally use 1060 aluminum, also can play a little heat dissipation effect.
