Cómo identificar la calidad de las luces de panel LED de techo integradas
En comparación con otras lámparas, las lámparas LED tienen ventajas sobresalientes: ahorro de energía, larga vida útil y protección ambiental ecológica. Sin embargo, la calidad de las lámparas LED varía mucho y los consumidores no saben cómo elegir. En vista de la feroz competencia actual en el precio de mercado de las lámparas de panel plano, la lista de una gran cantidad de productos de calidad inferior (los profesionales los llaman (productos inferiores, productos malos, productos malos) ha violado el valor real del ahorro de energía LED, mucho tiempo la vida, la protección del medio ambiente, etc.. Para aplicar la tecnología LED al campo del techo integrado, ha afectado seriamente el desarrollo saludable de las luces de panel LED de techo integradas.Cómo distinguir las ventajas y desventajas de las lámparas y linternas LED debe comenzar desde el siguientes aspectos:
1. Look at the overall "power factor of the lamp": a low power factor means that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamp. .
The power factor level can be detected with the "power factor meter"! Generally, the power factor of exported LED lamps is required to be above {{0}}.85. If the power factor is lower than 0.5, it should be said that unqualified products or waste products not only have a short lifespan, but also the actual power consumption is about twice as high as the nominal value. That is to say, compared with ordinary energy-saving lamps, it does not save electricity at all! So, this is why LED lamps need to be equipped with high-quality, high-efficiency drive power!
For consumers who do not have a "power factor meter", another method is to use an "ammeter" to detect two similar products with the same nominal power. The more you do not save electricity! At the same time, the current is unstable, which is not good for the life of the lamp bead and the life of the overall lamp!
2. Look at "lamp heat dissipation conditions - material and structure": LED lamp heat dissipation is also very important. Lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads work at high temperature, and the light decay will be Very large, the lamp life will be reduced.
En la actualidad, los principales materiales de disipación de calor utilizados son cobre, aluminio y PC. La lámina de aluminio, el aluminio para automóviles (perfil de aluminio, aluminio extruido) es el segundo, el aluminio fundido es el peor y el efecto de disipación de calor del inserto de aluminio es el mejor.
3. Look at "lamp bead quality": lamp bead quality depends on chip quality and packaging technology.
