لماذا مصابيح السقف LED أغلى من مصابيح السقف التقليدية؟
The application of LED is more and more extensive, and it has become the necessary lighting method for energy-saving lighting transformation in many places such as schools, factories, hotels, roads, etc. Among them, LED ceiling lamps are widely used in hotel lobbies, guest rooms and living room decoration of families, so why consume Will consumers choose LED ceiling lamps instead of traditional lamps?

①Low luminous efficiency: The whole light efficiency of energy-saving lamps with ballasts is only 55lm/W, and the highest high-power U type is only 80lm/W. And because all of these ceiling lights are mostly T5 tubes, bent into various shapes. But no matter what shape it is finally bent into, it is 360-degree light, and the upward 180-degree light must be reflected back to become useful light. This reflection process will lose a lot of light.
②Contains heavy metals: As we all know, traditional fluorescent lamps contain mercury, and the lamps will evaporate when they heat up. Mercury is harmful to the human body. Long-term use of such lamps will affect human health.
③Short service life: Short service life is a common feature of traditional lighting fixtures.

In fact, we can also find a problem. In general, the determination of traditional lighting fixtures is only generated after comparing with LED lighting fixtures. Therefore, the determination of traditional lighting fixtures is in turn the advantages of LED lighting:
①High luminous efficiency: The luminous efficiency of the LED itself has reached more than 130lm/W, so the overall luminous efficiency of the LED ceiling lamp can reach 100lm/W. And this efficiency is still increasing every year. It is estimated that by 2020, the luminous efficiency of LED itself will reach 240lm/W.
②No substances harmful to human body: no mercury, no ultraviolet radiation, no light pollution, no glass parts, shock resistance, vibration resistance, easy to transport.
③Long service life: The life of LED is 100,000 hours. After being made into lamps, it is actually recognized that the lifespan is at least 30,000 hours, and high-quality ones can achieve 50,000 hours, which is more than 10 times longer than fluorescent lamps.
④The lampshade is usually made of PC board: good light transmission, impact resistance, UV protection, light weight, flame retardant, bendable, and temperature adaptability.
Through comparison, we found that the LED ceiling light is better than the traditional ceiling light in all aspects, but the price of the LED ceiling light is a little more expensive than the traditional one. , Don't be greedy to buy cheap low-quality LED lights, not only can not achieve the purpose of lighting, but also dangerous!
