The choice of LED ceiling light mainly considers the following three aspects:
1, see lamps used radiator:
The speed of heat dissipation of the lamp determines the degree of light decay and service life of the entire lamp. The lamp beads work for a long time under high temperature conditions, the light decays very quickly, the service life is very short, and the ceiling lamp with poor brightness does not achieve the effect of the key lighting. LED ceiling light radiator program, the mainstream of the overall radiator, there is a single lamp beads a heat column, there are additional fan cooling methods. The size of the radiator and the quality of the aluminum material affect the speed of heat dissipation and also affect the overall stage lighting price.
2, see the lamp power supply (commonly known as the transformer):
The quality of the transformer also determines the lifetime of the entire lamp. Lamp beads can be used for more than 50,000 hours. However, if the transformer is broken, the entire lamp will not be bright. 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 the components, they can use the size and weight of the transformer and consult the manufacturer. The initial judgment of electrolytic capacitors and other aspects. The difference in the price of LED ceiling lights, transformer quality accounted for a small proportion.
3, understand the lamp beads brand and package:
The quality of the lamp beads determines the lighting effect of the LED ceiling lamp, and the packaging process affects the key factors such as lamp bead quality and heat dissipation. Lamp bead chips include American chips, Taiwan chips, and domestic chips. Different brands have large differences in price, and lighting effects vary greatly. The user can understand the lamp bead program by consulting the manufacturer, depending on the integrity of the manufacturer. The ceiling lamps with particularly low prices are produced by using the defective products laid down by the chip production line. The color temperature is not uniform, the brightness is poor, and the service life is short. Users need to pay attention.
