Led lamp decorative lamp features small size LED is basically a very small chip encapsulated in epoxy resin, so it is very small, very light. Low power consumption LED power consumption is very good, 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. The service life of the LED can reach 100,000 hours under appropriate current and voltage. High brightness and low calorific value because the energy released by LED during the transfer process is mainly in the visible range, 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 product with high efficiency and low calorific value. 。 The best LEDs on the market today are 32 lumens per watt, which are twice as many as tungsten filament bulbs, and people can predict that 60 lumens per watt will be emitted, and that fluorescent-like LEDs will appear in 2004.
