Let‘s meet the LED decorative lights

Because of its rich colors, small size, durability and energy saving, LED is very suitable for decorative purposes. Install it on the circuit board or flexible cable or other materials. LED can be used as the light source of letter lamp, sign board, track lamp, lamp tube and so on. Let‘s introduce the LED decorative lights in detail.

1. Small volume

LED is basically a very small chip, which is encapsulated in epoxy resin, so it is very small and very light. Low power consumption. The power consumption of LED is very low. Generally speaking, the working voltage of LED is 2-3.6v. The operating current is 0.2-0.03a. This means that it consumes no more than 0.1W of electricity. Long service life under proper current and voltage, the service life of LED can reach 100000 hours. High brightness and low heat because of the special constituent materials of LED, in the process of electron transfer, the energy released by LED is mainly concentrated in the range of visible light. Unlike other tungsten bulb, many of its electromagnetic energy is concentrated in the infrared region, which makes people feel very hot. That is to say, led converts almost all electric energy into light energy, so LED is high-efficiency Low calorie products. At present, the best LED on the market is 32 lumens per watt, which is twice that of tungsten bulb. Moreover, it can be predicted that 60 lumens per watt will be emitted. LEDs as bright as fluorescent lamps will appear in 2004. Environmentally friendly LED is made of non-toxic materials. Unlike fluorescent lamps, containing mercury will cause pollution. At the same time, LED can also be recycled. Rugged LED is completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There are no loose parts in the lamp body. These characteristics make the led not easy to be damaged

2. Decoration

Install it on the circuit board or flexible cable or other materials. LED can be used as the light source of letter lamp, sign board, track lamp, lamp tube and so on. Lighting with the development of LED technology, a combined LED is installed in some way. It can emit enough light for indoor lighting. For example, it can be used as display screen such as night lamp, table lamp and garden lamp. A typical use of LED is for information display and large screen display. They are widely used in stadiums, airports, business centers and so on. At present, the world‘s largest LED display is in Times Square in Manhattan, New York. LED backlight is very suitable for LCD backlight because of its small volume and low power consumption. The unity of color is the internal feature of LED. It emits very pure color in a very narrow frequency. This color is calculated by wavelength (LPK) (nm). Wavelength is an inherent characteristic of LED chip materials. Different materials will have different wavelengths, that is, different colors. We know that white light is a synthesis of all colors, but people‘s eyes do not need the synthesis of all colors in the spectrum, but only three colors (red, green and blue). Based on this principle, people think of many ways to manufacture white LED. The most typical manufacturing method is to bury the zinc blue LED in a phosphor that will emit yellow light.
