High, both environmental protection and efficient energy-saving.
Choose LED Day lantern mainly from the following three aspects to consider:
1. See the radiator used by the lamp: the speed of light bead cooling determines the light attenuation degree and service life of the whole lamp. Lamp bead long time in the high temperature condition work, the light fades quickly, the life is very short, but the brightness is too bad the day lantern, does not have the key illumination effect. LED Ceiling lamp Radiator scheme, the mainstream has a whole type of radiator, a single light bead cooling column mode, with the addition of fan cooling mode. Radiator size, aluminum quality affects the speed of cooling, but also affect the price of the whole lamp.
2, see the power supply (that is commonly known as the driver): drive quality also determines the life of the lamp, the lamp bead use of more than 50,000 hours no problem, but if the driver is broken, the whole light will not be lit. The electronic components and design schemes used in the drive determine the efficiency, power factor, stability, temperature appreciation and service life of the transformer. Users do not understand the knowledge of the components, can be driven by the size, weight, as well as consulting manufacturers to use electrolytic capacitors such as preliminary judgments. LED Day lantern price difference, driving quality accounted for a small proportion.
3. Understand the brand and package of the lamp bead: lamp Bead Quality decides the LED smallpox lamp illumination effect, the encapsulation craft affects the lamp bead quality, the heat dissipation and so on key factor. The lamp bead Chip has the American chip, the Taiwan chip, the domestic chip and so on. Different brands, the price difference is bigger, the illumination effect is also big difference.
Therefore, in the selection of LED ceiling lamp must pay attention to the ceiling of the radiator, drive, light bead factors and not only to consider the price.
