1. Look at the radiator used by the lamp: The speed of the lamp bead determines the degree of light decay and service life of the entire lamp. The lamp beads work under high temperature for a long time, the light decay is fast, the life is very short, and the ceiling light with poor brightness can not achieve the effect of key lighting. The radiator solutions for LED ceiling lamps include mainstream integrated radiators, single lamp beads and a cooling column, and external fan cooling. 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. It is no problem to use the lamp beads for more than 50,000 hours. However, if the transformer is broken, the entire lamp will not light up. The electronic components and design scheme 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 aspects of the size and weight of the transformer and the electrolytic capacitor used by the manufacturer. The difference in the price of LED ceiling lights, the quality of the transformer accounts for a large proportion.
3. Understand the brand and packaging of the lamp beads: the quality of the lamp beads determines the lighting effect of the LED ceiling lamp, and the packaging process affects the key factors of the quality and heat dissipation of the lamp beads. Lamp bead chips include American chips, Taiwan chips, and domestic chips. Different brands have large price differences and large differences in lighting effects. Users can learn about the lamp bead solution by consulting the manufacturer, depending on the manufacturer's integrity. Ceiling lights with a particularly low price are often manufactured using defective products from the chip production line. The color temperature is inconsistent, the brightness is poor, and the life is short. Users need to pay attention
