The LED decorative lamp body does not produce ultraviolet rays

LED single tube power 0.03~0.06 watts, using DC drive, single tube driving voltage 1.5~3.5 volts, current 15~18 mA, fast response, can operate at high frequency. Under the condition of the same lighting effect of LED decorative lights, the power consumption is one ten thousandth of that of incandescent bulbs, and one half of that of fluorescent tubes. It is estimated in Japan that if LEDs with twice the luminous efficiency are used to replace half of Japanese bulbs. Incandescent and fluorescent lamps. The equivalent of 6 billion liters of crude oil can be saved annually. In the case of bridge guardrail lights, a fluorescent lamp with the same effect is more than 40 watts, while the power of each LED is only 8 watts, and it can be colorful.

The holiday LED decorative lights of the festival decoration lighting project use electronic light field radiation to emit light, and the filaments have disadvantages such as easy burning, heat deposition, and light attenuation. The LED lamp is small in size and light in weight, encapsulated with epoxy resin, can withstand high-intensity mechanical shock and vibration, and is not easy to break. The average lifespan is 100,000 hours. The service life of the festival LED decorative lamp body can reach 5-10 years, which can greatly reduce the maintenance cost of the lamp and avoid the pain of frequent lamp replacement.

The body of the holiday LED decorative light does not produce ultraviolet rays, so there will not be many mosquitoes around the light source like traditional lamps. Traditional lamps are lit by the high voltage released by the rectifier, and cannot be lit when the voltage is reduced. The holiday decorative lamp body can be lit within a certain range of voltage, and the brightness can also be adjusted.

The LED chips of holiday LED decorative lights will inevitably age during the lighting process, and then the light decays. Generally, after a period of use, the lamps will definitely be a little darker than the beginning, and the lower light decay can ensure a longer life. At a higher junction temperature, the light decay of the LED will gradually intensify as the temperature rises. Once the internal temperature of the LED exceeds the junction temperature, the light decay will increase in a straight line.

High luminous efficiency will reduce heat generation, and reducing heat generation can reduce light decay, and a higher junction temperature will reduce the requirements for radiators. Selecting high-grade chips is the best festival LED decorative light body. However, lamps with American CREE chips cannot be bought on a certain treasure, because they are too expensive, and the gap between chips of the same size is about 10-100 times, and the gap between finished products is even greater.
