What are the led lamps and lanterns of component parts
the LED lamps and lanterns of the primary components are:
the primary effect is to seal the LED panel lights, generally use 1060 aluminum, also can have a cooling effect.
2。 Device pendant
suspension wire, device used for device fixed bracket and other accessories.
3。 Reflective paper
will guide plate on the back of the corner reflection out to progress lights, for RW250 commonly.
4。 Led light source
generally led lights use 3528, also some people use 3014 and 5050. 3014 and 5050, capital low, slightly less, the key is the light spot planning difficult. 3528 high light efficiency good commonality.
5。 Drive power
there are two kinds of led drive power supply, one is using the constant current power supply, this form of power is high, the PF value up to 0. 95, cost-effective; Second, using constant pressure with constant current power supply, stable function, low power, however, high capital, generally use the power supply is primary export, the other requires authentication request, must use a safety power supply. Actually family using the constant current power supply is very safe, because users can access to the power supply, and the lamp body itself is a safe low voltage electrical use.
6。 Panel light aluminum frame
is the first channel of the led heat dissipation, brief appearance generous, can use ZY0907, selection of die stamping mould cost is low, cost is low; Die-casting aluminum structure of IP to higher grade, good appearance quality, whole is beautiful, but early into the mold cost is higher.
7。 LED light guide
the flank face 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. Network planning is not good, see the whole light efficiency is very poor, often appear bright two dark, perhaps appear in light with the light, may be visible partial dark space, brightness again or a different viewpoint. To progress the photosynthetic efficiency of light guide plate first by network planning, followed by the quality of the plate, but it is not necessary to superstition first-line brand of plank, qualified plate between the light transmittance in general. General small LED lights factory are directly buy share the use of light guide plate, not demand from proofing planning, more manufacturers use the version of the general quality qualification.
8。 LED diffuser plate
the light guide plate uniform export, still can rise to the fuzzy network effect. General use acrylic diffuser 2. 0 plate or PC material, almost is PS material, acrylic low capital and light transmittance is higher than the PC is a bit high, acrylic fragile anti-aging function is weak, the PC price a little expensive, but strong anti-aging functions. Diffuser in mount in the future can't see the outlets, 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 the diffusion plate material selection.
