How to buy LED panel lights

  LED panel lights have the following parts, so, in order to choose the right LED panel light, choosing the suitable component is the most correct way.

How to buy LED panel lights

  1 panel light aluminum frame:

  Is led cooling the main channel, simple and elegant appearance, you can use ZY0907, using die stamping tooling costs, low processing costs are low; die-cast aluminum frame IP rating can be a little higher, surface texture, and overall appearance, but the initial investment cost of mold higher.

  2.led source:

  Usually led lamp beads used 3528, it was also used 3014 and 5050 which would be lower cost, light efficiency slightly worse, the key is its light guide network design problems.

  3.LED light guide:

  LED light through the side outlets refraction so that light from the front even exported the LED panel light guide plate Quality control key points. Network design is not good, to see the overall optical efficiency on the poor, the middle light will appear on both sides generally dark, or there is a light at the light into the band, or focally dark area, then there are different angles or brightness inconsistent. To improve the efficiency of light guide plate depends mainly on network design, followed by the quality of the plate, but do not need superstition famous line of the plate, the light transmittance pass between the plates is usually almost the same. General Factory is a small LED light guide plate directly buying public use, you do not need to re-proofing design, many manufacturers use the public version of the usual quality standards.

  4.LED diffusion plate:

  The uniformity of the light guide plate export, but also play the role of fuzzy dot. General use acrylic diffuser plate or sheet 2.0 PC material, almost is PS material, acrylic low cost and high transmittance higher than the PC, acrylic brittle weak anti-aging properties, PC prices slightly expensive, but anti-aging properties Strong. Installed after the diffuser plate can not be seen in the network, and the transmission rate to about 90%. Acrylic light transmittance at 92%, PC was 88%, PS probably also 80%, we can according to demand diffuser plate material selection, most manufacturers are using acrylic materials.

  5 reflective paper:

  Reflected off the back corner of the light guide plate in order to improve light efficiency, generally RW250.

  6 Rear cover:

  Main role is sealed LED panel lights, usually with 1060 aluminum, can also play a little cooling effect.

  7 Power Supply:

  There are two kinds of led power supply, one using constant current power supply, this mode efficiency, PF value up to 0.95, cost-effective; two is to use the constant voltage with constant current power supply, stable performance, but low efficiency, high cost, general use This power is mainly exported, the other required certification requirements, safety regulations require the use of a power supply. In fact, a constant current power supply for home use is safe, because the user is difficult to reach the power supply and lamp body itself using a safe low voltage.

  8 Installation accessories:

  Suspension wire, mounting brackets and other accessories for mounting.

  From the perspective of quality control, to improve the optical efficiency of the additional money on the LED light source and LED light guide plate is the most effective, from the marketing point of view, the additional money to cover the aluminum frame pendant, etc. can improve product quality.

LED panel light is a upscale indoor lighting, its external borders made from aluminum by anodic oxidation, the light source is LED, the entire lighting design beautiful and simple, luxurious atmosphere, both good lighting effects, but also gives brings a feeling of beauty. LED panel lights unique design, high transmittance of light through the light guide plate to form a homogeneous plane glow, illumination uniformity, light, soft, comfortable yet bright, can relieve eye fatigue. LED panel lights can also radiation, does not irritate the pregnant women, the elderly, children’s skin.

Compared with other lighting products, LED panel lights are very prominent advantages: ultra-thin, ultra-bright, ultra energy-efficient, long life, ultra-easy peace of mind! Green. However, LED panel light quality varied widely, consumers do not know how to choose? Given the current market price of flat-panel lights fight the vicious competition, a large number of substandard products to market (professionals call it (sub-standard and poor goods, bad lot) , has violated the LED energy-saving, long life, environmental protection and other real value, contrary to the LED technology to the field of integrated ceiling meaningful and integrated ceiling seriously affected the healthy development of LED panel lights, Manufacturers for LED panel lights have the responsibility to introduce and explain how to choose LED Panel lights or LED panel lights to identify good and bad ways:
First, look at the whole “lighting power factor”: if the power factor is low, indicating that circuit design of lighting will greatly be reduced. Also, if power factor is low, the use of even the best LED lighting life is not president . Power factor level, with the “power factor meter” can be detected. General export LED panel light power factor required to achieve above 0.85. Power factor is less than 0.5, it should be said substandard products or refuse products, not only short-lived, and the actual electricity consumption to be higher than the nominal about twice, that is, compared with the ordinary energy-saving lamps, simply not saving. So, this is why LED panel light needs with high-quality, high-efficiency drive power of reason. There is no “power factor meter” is used to detect power factor LED lighting to consumers, there is a way to use the “meter” to test two a nominal power of the same similar products, the greater the current and current harmonics greater, indicating the actual electricity consumption is large, but also the less saving! Meanwhile, the current instability, and the overall life of the lamp beads adverse lighting life!
Second, look at “Lighting cooling conditions – materials, structures”: LED lighting heat is also very important, the same lighting and power factor with the quality of the lamp beads, if the conditions are not good heat dissipation, light bead work at high temperatures, the light fades will be greatly reduced. Currently, the use of the heat sink material are copper, aluminum, PC, thermal conductivity of copper than aluminum, PC better off than the thermal conductivity of aluminum, are most aluminum radiator materials in general, preferably for the insert piece, aluminum die-casting aluminum (Al profiles, extruded aluminum), followed by the worst is cast aluminum, aluminum inserts cooling effect is best.
Third, look at “light bead quality”: LED chip quality depends on the quality and packaging technologies.
Chip Brand of three camps:
The first camp to Europe, America, Japan, as the representative of manufacturers, including Cree, Osram, Nichia, Toyoda Gosei, etc.;
Second camp in the United States, South Korea, China Taiwan as the representative of manufacturers, including Bridgelux, Seoul, Epistar, etc.;
Fourth, drive power. The power of life relative to other parts of lighting, the life expectancy is much shorter, the power of life affect the overall life of lighting, lamp beads theoretical life of 5-10 million hours, and the power of life of 0.2 -3 million hours, power supply design and material selection will determine the power of life. Aluminum exterior with a good power-driven than plastic, one of its good heat dissipation, and second, transport and use can effectively protect the inside of the parts are not to be crushed and loose, lower power drive failure rate.
Fifth, luminous efficiency. Based on the same power lamp beads, light efficiency is higher, the higher the brightness, the same illumination, power consumption is smaller, more energy efficient.
Sixth, power efficiency, the higher the better power efficiency, higher, indicating that the power consumption of the power supply itself is smaller, the greater the power output.
Seventh, China’s LED lighting safety standards have been introduced, according to state regulations, please choose LED lighting safety standards.
Eighth, a good quality LED panel lights, in addition to several key aspects mentioned above, the workmanship is an external manifestation of the perfect product. In short, a good quality LED panel lights, drive power is high quality, good heat dissipation, high-quality chips, meet the safety standards of several aspects of the perfect combination! Merely emphasized that any party can not be called a qualified products !
