What is a ceiling lamp?
Ceiling chandelier is a kind of lighting and modern decorative lamp with noble taste, which is very suitable for shopping malls, supermarkets, hotels, jewelry counters and high-end houses. Traditional ceiling lamps mainly combine halogen light sources. The main advantage of LED ceiling lamp is low carbon and energy saving, which adapts to the global trend of energy saving, emission reduction and low carbon life. It is an ideal choice for modern high-light home. The lamp can reach 50000H under normal use, which is equivalent to the life of 50 incandescent lamps. Different from spotlights, ceiling lamps are mainly scattered light sources, with wide irradiation area, soft light and uniform light spots.
Selection method of ceiling chandelier
LED ceiling lamp adopts LED light source packaged by special technology and technology, which has higher luminous flux. Because of its good heat conduction and heat dissipation effect, LED light source has less attenuation, longer service life, higher safety performance, environmental protection, high efficiency and energy saving. The choice of LED ceiling chandeliers is mainly considered from the following three aspects:
Look at the radiator for the lamp: the heat dissipation speed of the lamp bead determines the degree of light attenuation and service life of the whole lamp. Lamp beads work at high temperature for a long time, with fast light decay and short service life. The ceiling lamp with poor brightness can't achieve the effect of accent lighting. The main heat dissipation schemes of LED ceiling lamp include integral radiator, one lamp bead, one cooling tower and external fan. The size of radiator and the quality of aluminum affect the speed of heat dissipation and the price of the whole lamp.
Look at the power supply of the lamp (commonly known as drive): the quality of the drive also determines the life of the whole lamp. It's okay to use the lamp beads for more than 50 thousand hours, but if the drive is broken, the whole lamp won't light up. The electronic components and design scheme used in the driver determine the efficiency, power factor, stability, temperature rise and service life of the transformer. If users don't know the knowledge of components, they can make a preliminary judgment from the size and weight of the driver and the electrolytic capacitor used by the manufacturer. The price difference of LED ceiling chandeliers accounts for a large proportion in driving quality.
Understand the brand and packaging of lamp beads: the quality of lamp beads determines the lighting effect of LED ceiling lamps, and the packaging technology affects the quality and heat dissipation of lamp beads. There are American chips, Taiwan Province chips and domestic chips. Different brands differ greatly in price and lighting effect.
The above is a detailed answer to what is a ceiling chandelier and how to choose it. I wonder if you are satisfied with our introduction.
