The benefits of dimming the Square LED Panel Lights
 Square LED Panel Lights manufacturer believes that, as an environmentally friendly and energy-saving Square LED Panel Lights, which in addition to the same lighting with other lighting effects, there is a general incandescent lamp does not have the special performance - dimmable, dimmable Of the Square LED Panel Lights wider than ordinary lighting, but also in energy-saving emission reduction will also play a greater role.
The previous year the country's total electricity consumption reached 2.7 trillion degrees, of which only lighting electricity has about 300 billion degrees, if the energy consumption is only one-third of the traditional lighting fixtures Square LED Panel Lights, the energy-saving effect Is self-evident, so with the dimming characteristics of the Square LED Panel Lights more by the consumer's favorite and welcome.
The use of dimming technology to reduce the output power will significantly improve the working environment of Square LED Panel Lights, extend lamp life and improve reliability. The key factor affecting the reliability of the Square LED Panel Lights is temperature.
Whether it is LED drive power or LED chip, the higher the ambient temperature, its life and reliability will be a sharp decline. When the ambient temperature is 25 ℃ LED power life of up to 320,000 hours, and when the temperature rose to 60 ℃, Square LED Panel Lights power supply life will be shortened to only 35,000 hours.
The higher the temperature, the LED chip's light failure is also significantly increased. Square LED Panel Lights of the light and its junction temperature is closely related to the so-called junction temperature is the temperature of the semiconductor PN junction, the higher the junction temperature, LED light sooner the light failure, that is, the shorter life.
If the junction temperature is 105 ℃, brightness down to 70% of the Square LED Panel Lights life of only more than 10,000 hours; junction temperature 95 ℃ when the Square LED Panel Lights life has 20,000 hours; and junction temperature reduced to 75 ℃, life Can be up to 50,000 hours, 65 ℃ when the life can be extended to 90,000 hours. To sum up, the key to extending the life of the Square LED Panel Lights is to reduce the junction temperature.
With dimming technology, with the output power to reduce the drive power supply itself will be reduced, the shell temperature will also decline. When the ambient temperature is 25 ℃ full load output, the case temperature is 50 ℃, while the use of dimming technology to control the output only 50% of the power, the shell temperature dropped to 40 ℃, life will be doubled, reliability can be increased by 25% 40%.
 Now LED lighting is no longer a symbol of high-tech products, after years of development there are many LED lighting products become popular home lighting preferred, Square LED Panel Lights to ultra-thin, energy saving, ultra-brightness, especially by the vast number of consumers favor today Will share with you how to choose a good Square LED Panel Lights method.
First, from the material aspects to choose. LED lighting is basically a shell accessories, LED light source and lamp drive composition, for the Square LED Panel Lights for high-quality products, of course, is particularly important.
Square LED Panel Lights Enclosure Accessories are generally made of aluminum alloy frame + light guide plate + light guide plate + backplane. Aluminum alloy shell is very easy to distinguish from the appearance, a good aluminum alloy shell texture and surface treatment of fine, consistent use of ten years are not easy to oxidize discoloration, poor shell is usually thin aluminum feel light, squeeze easily deformed by hand. In the Square LED Panel Lights shell accessories is the most important is the light guide plate, which is our industry professional identification of high quality panel lights an important indicator.
Second, LED light source. Of course, this first of all to thank our country for the industry attention and support, the current low-power patch Square LED Panel Lights lamp beads chip has been Sanan as a leader, and good quality. So as the panel lights in recent years preferred Square LED Panel Lights light source for the domestic San'an chip package 2835 light source. But if the customer is relatively high product requirements, we generally preferred or Samsung, Japan or Osram and other first-line brand. There may be a lot of friends here for the high demand for the election of foreign brands of LED light source, I would like to answer a popular words you, we light source and foreign brands are almost the same quality, but the product performance or foreign products to be assured that some , This you know
