Power Factor, Stability, Temperature Rise

- Jul 27, 2018-

The ambient temperature of the LED ceiling light is generally -30 degrees + 50 degrees, and its voltage is AC/DC 12V, 24V, 110V, 220V, and can reach 50,000 hours of life when used.

LED ceiling light adopts LED light source with special process and technology package, and the luminous flux is higher. Because of its good heat conduction and heat dissipation effect, LED light source has less attenuation, longer service life and higher safety performance, which is environmentally friendly and energy efficient.

The choice of LED ceiling light is mainly considered from the following three aspects:

1. Look at the radiator used by the luminaire: The speed of the 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 of the lamp (known as the drive): The drive quality also determines the life of the whole lamp, the lamp is used for more than 50,000 hours no problem, but if the drive is broken, the whole lamp will not shine. The electronic components and design scheme used in the drive determine the efficiency, power factor, stability, temperature rise and service life of the transformer. If the user does not know the component knowledge, it can be judged from the size and weight of the driver and the electrolytic capacitor used by the manufacturer. The difference in the price of LED ceiling lamps, the driving quality 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 lamp, 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.
