How to choose good quality LED panel light products?
LED panel lamps are widely used in high-standard lighting places such as large commercial buildings and office buildings due to their simplicity and generosity.
In the large-area VDT office area, LED panel lamps give full play to its advantages. The surface brightness of LED panel lamps is not high and is very uniform, which effectively reduces the reflected glare on the display screen when installing grille lamps or bracket lamps, and greatly improves the aesthetics of the indoor ceiling.
The LED panel light has little effect on the LED lamp beads at about 60 degrees, but this temperature can still be reduced by selecting appropriate heat dissipation materials, so that the temperature of the LED panel light can be reduced to below 50 degrees. In addition, the size of the power will also affect the temperature of the LED panel light. Because of the low power of the LED light, all the heat can be poured out through its own lens, which is easy to solve.
Compared with high power, the heat dissipation problem is more difficult. The structure of high-power LED lamp beads is very different from that of low-power lamp beads. Therefore, the heat dissipation method of high power needs to be solved by external force. Aluminum plate, (aluminum has better heat dissipation characteristics) rely on aluminum plate to dissipate heat, such as spotlights and the same, should solve the heat dissipation problem in this way, the total output power is generally more than ten W, in addition to using aluminum plate to conduct heat, also Rely on the fan to dissipate heat.
Good heat dissipation conditions are a guarantee for the long service life of LED panel lights. Therefore, when purchasing LED panel lights, you should choose LED panel lights produced by powerful companies. In 2014, China Quality Certification Center issued CQC 3147-2014 LED "Technical Specification for Energy Conservation Certification of LED Panel Lamps", which stipulates luminous flux, lamp efficiency, durability test, chromaticity performance, color rendering index, and spatial color inconsistency. , According to the characteristics of the product, the requirements for the distance-to-height ratio, brightness limit and surface brightness uniformity are put forward. The quality of LED panel lamps in the lighting market is uneven. How to choose high-quality products, it is recommended to use products certified by CQC for energy-saving LED panel lamps.
