The structure of the LED flat light of knowledge

once someone lamp will be no specific shape to predict the future, the future of the lamp will be part of the building, is you can't easily tell it at a glance. And LED flat light, some say, it is at this stage lighting to this field ahead of a major performance.

LED flat light to show refers to the intensity of illumination uniformity, good characteristics such as higher, light even soft, comfortable, is widely used in offices, schools, hospitals, shopping malls, household etc, become a LED replace the traditional grating light plate of the best products.

structure mainly includes the framework of LED flat light, diffusion plate, guide plate, lamp beads, drive power, aluminum plate etc.

1, frame, frame strength influence durability: framework is an important part of the flat light, high strength of frame lamp plate was made more durable. The edge of LED flat light frame material is qualitative different, its cooling performance are also different. According to statistics, the current framework of flat light materials are aluminum alloy, steel, PC, A6063, aluminium, steel and other materials.

2, diffusion plate: different material light transmittance: is the role of diffusion plate light guide plate evenly spread out, also can have the effect of fuzzy network, main materials used are acrylic, PC, PS, etc. According to understand, acrylic light transmittance in 92%, 88% PC, PS is probably 80%, acrylic high light transmittance is PC material, and lower costs, at the same time the anti-aging performance weak; The PC material price is expensive, but strong anti-aging performance.

3, guide plate, plate had a great influence on light efficiency: the role of the guide plate is in parallel to the direction of the light through the light refraction into perpendicular to the direction of the plate, and the reflective paper shall refraction of light guide plate to plate on the back of the light reflected. In the process, even as much as possible to reduce the light failure, in general, photosynthetic efficiency depends largely on the network design of light guide plate, sheet followed by choice.

4, power supply: constant current power supply mode of high efficiency: there are two kinds of LED lamps and lanterns drive power supply mode, is a constant current power supply, the model of high efficiency, PF value up to 0. 95, cost-effective; The other is a constant pressure constant current power supply, stable performance, but low efficiency and high cost.

the above is the structure of the LED flat light, LED flat light, with its illumination uniformity, refers to the higher good and light even soft, comfortable, gradually become LED replace the traditional grating light plate of the best product, it will be in the school and other developments in the field of indoor lighting space will be more and more big.
