The inherent characteristics of LED determine that it has many advantages. More and more LED lights are seen in various lighting applications. LED backlight module is a common application of LED. This article will introduce the characteristics of related LED backlight modules.
This passage is going to talk about the followings of the characteristics of LED backlight module:
1.Popular lighting source-LED
2.The advantages of LED backlight module
3.Precautions for using LED backlight module
LED is a high-quality light source that is widely used. It has the characteristics of small size, long life, environmental protection and energy saving. LED is a high-quality light source that is widely used. It has the characteristics of small size, long life, environmental protection and energy saving. The same is for LED backlight modules.
The LED backlight module is small in size. Since the LED is basically a small chip encapsulated in epoxy resin, it is very small and very light.
And LED power consumption is quite low, DC drive, ultra-low power consumption, electro-optical power conversion close to 30%. In the same lighting effect, LED energy saving is nearly 80% than traditional light sources.
Some people call LED light sources as long-life lamps, and LED backlight modules are no exception. It is a solid cold light source, epoxy resin encapsulation, there is no loose part in the lamp body, and there are no shortcomings such as easy burning of the filament, heat deposition, and light decay. Under the right current and voltage, the service life can reach 60,000 to 100,000 hours, which is more than 10 times longer than that of traditional light sources.
LEDs are made of non-toxic materials, unlike fluorescent lamps that cause mercury pollution, and LEDs can also be recycled. There is no ultraviolet and infrared in the spectrum, neither heat nor radiation, low glare, cold light source, safe to touch, and a typical green lighting source.
The cost of the LED backlight module is relatively low. The basic acrylic luminous characters are also called advertising light box characters, which are composed of characters and lights inside, so the cost is relatively high. The back light module is on the inner layer of the lamp, which is not easy to be damaged. The shell is assembled separately. Usually, it is enough to wipe the dust off the shell with the light. The module is shiny and well-proportioned. Because acrylic luminous characters are limited by the size of the strokes of the characters, there is generally no way to touch the strokes that cannot be put in the group. Therefore, there will be an area with different chromaticity of the characters. The luminous characters are equipped with LED A single lamp comes up, therefore, the luminous characters outside the LED will not have such a situation (unless the lamp is broken).
Although the LED used in the LED backlight module is a hard and durable light source. However, there are still precautions for use, which are briefly described below.
The LED is completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There is no loose part in the lamp body, so that the LED is not easily damaged. According to the temperature characteristics of the LED, the temperature rises by 5°C, and the luminous flux drops by 3%. Pay attention to the working temperature and storage temperature of the LED whether it is used in winter or summer. Generally, the lowest working temperature of LED is -25℃ and the highest is 85℃, and the lowest storage temperature is -40℃ and the highest is 100℃. The minimum working temperature of OUT-DOOR LED LAMPS is -20℃ and the maximum is 60℃, and the minimum storage temperature is -20℃ and the maximum is 70℃.
