How to choose LED downlight?
Select LED Downlights mainly from the following three aspects to consider:
1. The LED Downlights radiator:
The speed of heat lamp beads determines the degree of light fades and service life of the whole lamp. Lamp beads for a long time in a high temperature state, the light fades quickly, life is very short, bad the brightness ceiling light, will not achieve the effect of accent lighting.
LED ceiling radiator programs, Mainstream integral heat sink, single lamp beads a cooling column, plus fan cooling mode.
The size of the radiator, the quality of the aluminum material affects the speed of heat dissipation, and also affects the price of the whole lamp.
2. The power of the LED Downlights:
Transformer quality determines the whole lamp life the lamp beads use more than 50,000 hours, no problem, but the transformer if it is bad, the whole lamp also bright not afford. Electronic components used in the transformer design transformer efficiency, power factor, stability, temperature rise, life.
Users do not understand the components of knowledge, from the transformer size, weight, and consult the manufacturer using electrolytic capacitors, preliminary judgment. LED ceiling price differences in the quality of the transformer is not a small proportion.
3. The LED Downlights beads brand and package:
The quality of the decision of the lamp beads LED ceiling lighting effects, the packaging process affect the quality of the lamp beads, cooling and other key factors. Lamp beads chips American chip, the Taiwan chip, domestic chips. Different brand, price differences, the lighting effects are also great differences.
Users can be learned through consultation with the manufacturer the lamp beads programs, depending on the manufacturer degree of integrity. Particularly low price ceiling light, many use the chip production lines and lay the defective products to produce inconsistent color temperature, brightness, short life, users need to pay attention.
