The choice of LED ceiling light is mainly considered from the following three aspects:
1. Look at the radiator used in the luminaire:
The speed of heat dissipation of the lamp determines the degree of light decay and the service life of the whole lamp. The lamp beads work under high temperature for a long time, the light decays quickly, the life is very short, and the ceiling lamp with too bad brightness can not achieve the effect of accent lighting.
LED ceiling lamp radiator solution, the mainstream has an integrated radiator method, a single lamp bead, a cooling column method, and an external fan cooling method.
The size of the radiator and the quality of the aluminum material affect the speed of heat dissipation and also affect the price of the whole lamp.
2. Look at the power supply of the luminaire (that is, the commonly known transformer):
The quality of the transformer also determines the life of the whole lamp. It is no problem to use the lamp for more than 50,000 hours, but if the transformer is broken, the whole lamp will not shine. The electronic components and design schemes used in the transformer determine the efficiency, power factor, stability, temperature rise and service life of the transformer.
If the user does not understand the component knowledge, it can be judged from the size and weight of the transformer and the electrolytic capacitor used by the manufacturer. The difference in the price of LED ceiling lamps, the quality of transformers accounts for a large proportion.
3. Understand the brand and packaging of the lamp bead:
The quality of the lamp bead determines the lighting effect of the LED ceiling light, and the packaging process affects the key factors such as the quality of the lamp bead and heat dissipation. Lamp beads chips include US chips, Taiwan chips, and domestic chips. Different brands have different price differences and different lighting effects.
