![]() ![]() It also depends on the climate of the region. PS will probably last for two years, and MAS will last for three years. PS and MAS will turn yellow due to long-term use. Commonly used sheets are PMMA (acrylic), MAS, and PS, with prices from high to low. Generally speaking, the light efficiency of the light guide plate depends largely on the design of the dots, followed by the choice of the plate (light transmittance). In this process, it is also necessary to reduce the light decay as much as possible. The function of the light guide plate is to refract the light parallel to the direction of the light-transmitting plate into the direction perpendicular to the light-transmitting plate, and the light guide plate is refracted to the back of the panel light by the reflective paper. The light guide plate is a component of the side-emitting panel light. The direct-lit panel light generally needs far fewer lamp beads than the side-emitting panel light because the light-emitting of the lamp beads is scattered by the optical lens. The commonly used lamp beads are SMD2835 and SMD4014, the brands are HONGLI, SANAN, SAMSUNG, Lumileds (formerly Philips), and the price of the brand lamp beads will be more expensive. The type, brand, and quantity of LED chips will affect the light effect, and the luminous flux will also affect the price. ![]() In addition, the weight of the frame will also affect the price. The general frame has a flat frame and step frame according to the style, and the price will be different. The welding frame will be stronger and the price will be more expensive than the splicing frame. The most commonly used is the aluminum frame (small panel light, with a plastic shell), and it is divided into splicing and welding frames. At present, the frame materials of panel lights mainly include aluminum alloy, steel, PC, A6063, aluminum-plastic, steel and other materials. The side frame of the LED panel light is made of different materials, and its heat dissipation performance is also different. The frame is an important part of the panel light, and the high-strength frame makes the panel light more durable. LED panel lights mainly include the following parts: Matching different accessories (clips, surface-mounted frameļ¼ or steel ropes) enables them to be mounted on many surfaces and used in a variety of applications. The light passes through the light guide plate with high transmittance to form a uniform plane luminous effect, with good illumination uniformity, soft light, comfortable and bright. LED panel light is a high-end indoor lighting fixture. The middle part of the panel light turns yellow Yellow light appears around the panel light frame Dark areas appear around the panel lights What are the common quality problems of panel lights?.Edge-lit LED panel lights working principle.What wattages and dimensions do panel lights have?.Once Ankur Lighting receives the product, the replacement product will be dispatched to you within a day or two.If the claim is not fair, you will be required to bear the shipping costs for the product.
