LED decorative lamps from modeling lamp manufacturers are very suitable for decorative purposes because of their rich colors, small size, durability and energy saving. When it is installed on the circuit board, flexible cable or other materials, LED can be used as the light source of letter lamp, signboard, track lamp, lamp tube, etc.
LED decorative lamp is basically a small chip encapsulated in epoxy resin, so it is very small and light. LED power consumption of modeling lamp manufacturers is very low. Generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.2-0.03A. That is to say, 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 the energy released by LED in the process of electron transfer is mainly concentrated in the range of visible light, unlike other tungsten filament bulbs, its electromagnetic energy is mostly 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 a high-efficient and low heat product.
At present, the best LED decorative lamps on the market are 32 lumens per watt, twice as many as tungsten filament bulbs. It can be predicted that 60 lumens per watt will be emitted, and LEDs as bright as fluorescent lamps will appear in 2004. Environmental LED is made of non-toxic materials. Unlike fluorescent lamps, which contain mercury, it will cause pollution. At the same time, LED can also be recycled. Durable LED is completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There is no loose part in the lamp body, which makes the LED not easy to be damaged.
LED light output will vary with its chip type, packaging method and other differences. But there is no uniform standard to measure its brightness in the world. Generally speaking, the total luminous amount of LED is measured by the height of a light point in the axial direction, and is represented by (MCD) candles. A LED with a very high degree value does not mean that its light output is very high. To calculate its total light output, you must take its luminous angle into account. The viewing angle of the LED is also a function of the LED chip type and the light splitting or scattering function of its epoxy resin shell. LEDs of different chips and packages will have different brightness values. If two LEDs have the same brightness value, the larger the luminous angle is, the greater the light output is.
