1. Look at the radiator used by the lamp:
The speed of heat dissipation of the lamp beads determines the degree of light decay and service life of the whole lamp. The lamp beads work under high temperature for a long time, the light decays quickly, and the lifespan is very short, and the ceiling lamp with poor brightness cannot achieve the effect of accent lighting.
The mainstream LED ceiling lamp radiator solutions include integral radiator, a single lamp bead and a cooling column, 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 the price of the entire lamp.
2. Look at the power supply of the lamp (commonly known as the transformer): the quality of the transformer also determines the life of the entire lamp. The lamp beads are used for more than 50,000 hours. There is no problem, but if the transformer is broken, the entire lamp will not be able to light up. 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 knowledge of components, he can make a preliminary judgment from the size and weight of the transformer, as well as the electrolytic capacitor used by the manufacturer. The quality of the transformer accounts for a large proportion of the price difference of LED ceiling lamps.
