What are the materials of the LED panel light power supply ? The main components of the LED panel light are described below . 1. Panel light aluminum frame: It is the main channel for LED heat dissipation. It has a simple and elegant appearance. It uses T6063, drawing die, low mold opening cost and low processing cost. The stretched aluminum frame has a low IP rating, good surface texture and overall beauty. 2. LED light source: Usually LED lamp beads use 5630, others use 3528 and 3014. 3014 and 3528 cost is low, the light effect is slightly worse, the key is that its light guide dot design is difficult. The South Korean Samsung 5630 lamp bead used by Haixiangen Optoelectronics is a high-brightness LED lamp bead. Significantly >80+, light effect >75+ high efficiency and good versatility. 3. LED light guide: The side LED light is refracted through the dots to evenly lead the light from the front side. The light guide plate is the key point for the quality control of the LED panel light. Poorly designed network, see the overall effect on the poor light, the light is not uniform, there will be bright middle dark sides, or have occurred at the light into the light band, visible or local dark area, then the brightness is inconsistent or varying angles . To improve the efficiency of the light guide plate depends mainly on the design of network points, followed by the quality of the plate, but did not need superstition famous line of the plate, the light transmittance between the plates is usually qualified almost the same. Generally small LED lamp factories are directly buying public use with the light guide plate, there is no need to re-design proofing, the quality of the public version of the more commonly used qualified manufacturers. 4. LED diffuser: The light of the light guide plate is evenly extracted, and the function of the fuzzy dot can also be played. Diffusion plate using 2.0 grams alkylene or PC sheet material, is almost PS lower cost materials, acrylic and slightly higher light transmittance than PC, acrylic embrittlement weak anti-aging properties, PC prices slightly expensive, but the anti Aging performance is strong. Dot can not be seen in the diffusion plate installed later, and a light transmittance of 90% to the left and right. Acrylic light transmittance at 92%, PC is 88%, PS probably also 80%, we can choose according to the needs of the diffusion plate material, most manufacturers are currently using acrylic material 5. Reflective paper: Reflecting the residual light on the back of the light guide to improve the light efficiency. 6. Rear cover: The main function is to seal the LED panel light, generally using 1060 aluminum, which can also play a role in heat dissipation . 7. Drive power: First, the use of constant current power supply, this mode is high efficiency, PF value is up to 0.95, cost-effective; Second, the use of constant voltage with constant current power supply, stable performance, but low efficiency , high cost, the general use of this power supply is mainly exported, the other side A certified source is required and a safe power source is required. The advantage of USB Cable Type C is that it supports higher current, that is that more current can be passed by Type-C in the same time. In this way, the charging speed of the device can be accelerated. At present, the charging current of most Type-C data lines is generally 2A. If the charging rate of 3A is to be reached, a high-current wall charging matching it is required. That is to say, if the wall charge only supports 1A, whether it is charged with 2A or 3A data line, there is no difference fundamentally. If the current supported by the wall charging is 2A, and the type-C data cable of 2A/3A is matched, the effect can be significantly changed.
The highlights of Type-C interface are thinner design, faster transmission speed (USB3.1 up to 10Gbps) and stronger power transmission (up to 100W).The biggest feature of Type-C double-sided plugable interface is that it supports double-sided insertion of USBinterface. Officially solved the USB never insert the worldwide problem, the front and the back of the random plug.The USB Cable used with it must also be thinner and lighter.

In addition, the device equipped with the Type-C interface can be charged by connecting the mobile power supply through the Type-C cable or Usb C Cable. Users do not need to carry the charging cable, but can have the wall charging and Type-C cable. In addition, when selecting a Type-C charging cable, We should pay attention to the current limit. The charging data cable 1A does not have fast charging performance, 2A is the most commonly used Type-C charging data line, and 3A is the best data line at present. If you want to have fast charging effect, you must choose the Type-C charging data line with 3A current.
