Nowadays LED panel lamp is a common indoor lighting tool, the use of such lamps in various fields is also more and more common, because the panel lamp relative with other lamps, LED Panel Lights its beautiful, low consumption, long life, economic, practical environmental protection of the absolute advantage of the rapid occupation of the market, deeply loved by consumers.
1, Isolation Power: The program performance is relatively good, LED Panel Lights security and IC constant current performance is better, but the cost is higher.
2, non-isolated power supply: The cost of the program is moderate, but also the use of IC constant flow, but there will be a breakdown of the safety of the leakage, LED Panel Lights so the external results of the requirements of the luminaire must be an insulator.
3, drag-and-hold step-down: The program is the least cost of the three schemes, the simplest method, the use of the least device is a constant flow scheme. Therefore the cost is relatively low, mainly applies to the lamp configuration under 3w, also has the breakdown leakage safety hidden trouble, needs the good insulating shell.
LED panel light with its illuminance uniformity, LED Panel Lights display higher, light uniformity, comfort and other features, is widely used in offices, schools, hospitals, shopping malls, home and other places, to become the LED era to replace the traditional grille lamp plate the best products.
The frame is an important part of the panel light, and the high strength frame makes the panel lamp more durable. The frame of the LED panel lamp uses different material, LED Panel Lights its heat dissipation performance is also dissimilar. According to statistics, the current panel lamp frame materials are mainly aluminum alloy, steel, PC, A6063, aluminum, steel and other materials.
The effect of the diffusion plate is to disperse the light of the guide plate evenly, also can play the role of the fuzzy dot, the material that uses mainly has acrylic, PC, LED Panel Lights PS and so on. It is understood that acrylic transmittance in 92%, PC for 88%, PS probably 80%, acrylic material transmittance is higher than PC, and low cost, while its anti-aging performance is weak, but PC material price expensive, but anti-aging performance is strong.
The effect of the guide plate is to reflect the light in the direction of the guide plate perpendicular to the direction of the transparent plate, and reflected by reflective paper to reflect the light on the back of the panel light. In this process, but also to reduce the light attenuation as much as possible, in general, the light efficiency of the guide plate depends largely on the design of the DOT, LED Panel Lights followed by the selection of plates.
LED lighting has two types of driving power mode, one is constant current power supply, this mode of high efficiency, pf value of up to 0.95, cost-effective; the other is constant voltage with constant current power supply, stable performance, but low efficiency, high cost.
Side light-emitting panel light with light weight thin, easy to install the advantages of transport, the disadvantage is easy to glow uneven; The advantages of straight down panel lamps are sufficient brightness, the advantages of cost control, the disadvantage is that glare is unavoidable, LED Panel Lights there are dark areas, light body thick, transport installation is relatively inconvenient.
Side light-emitting LED panel light price relatively straight down price is expensive, because the side light-emitting LED panel lamp technology is relatively complex, LED Panel Lights which is determined by the side light-emitting product structure, side light-emitting LED panel light than the straight down technology and technology are complex, resulting in product yield and product uniformity is more difficult to control.
