How to choose a good 300x300 LED Panel Lights
Today, LED lamps are no longer a symbol of high-tech products, after years of development there are many LED lighting products become popular home lighting preferred, 300x300 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 300x300 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 300x300 LED Panel Lights for high-quality products, of course, is particularly important.
300x300 LED panel light housing accessories are generally aluminum frame + light guide plate + expansion board + backplane composition. 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 300x300 LED Panel Lights housing 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, at present China's low-power SMD LED lamp beads chip has been Sanan as a leader, and good quality. So as the panel lights in recent years preferred LED 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
Third, the power drive. Power drive can be said that the lamp drive center, the saying goes, a good horse with a good saddle, 300x300 LED Panel Lights no matter how good the manufacturers say depends on the power supply. How is the difference between the power-driven excellent and inferior? Here to tell you generally quick selection method, one certification such as 3C, TUV, UL and other related certification, the second is to ask the power brand,
300x300 LED panel light manufacturers that, as environmentally friendly and energy-efficient 300x300 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 300x300 LED Panel Lights for a wider range than ordinary lighting, but also in energy saving 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 300x300 LED Panel Lights, the energy-saving effect Is self-evident, so with the dimming characteristics of the 300x300 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 300x300 LED Panel Lights to extend the lamp life and improve reliability. The key factor affecting the reliability of the 300x300 LED panel light 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 ℃, 300x300 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. LED light failure 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 source soon decline, that is, the shorter life expectancy.
If the junction temperature of 105 ℃, brightness down to 70% of the 300x300 LED Panel Lights life is only more than 10,000 hours; junction temperature 95 ℃ when the 300x300 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. In summary, the extension of 300x300 LED Panel Lights life is the key 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% Rhithers. Points wanted outcome outcome.
