The body of the festive decorative lamp does not produce ultraviolet rays, so there are not many mosquitoes around the lamp source like traditional lamps. Conventional luminaires are lit by the high voltage released by the rectifier and cannot be lit when the voltage drops. The festival decorative lamp body can be lit within a certain range of voltage, and the brightness can also be adjusted.
The LED chip of the holiday decorative lights will inevitably age in the process of luminescence, and then the light decay, the general lamps will definitely be darker than the beginning after a period of time, and the lower light decay can ensure a longer life. The higher the enchantment temperature, the light decay of the LED gradually intensifies with the rise of temperature, and once the internal temperature of the LED exceeds the enchantment temperature, the light decay will rise in a straight line mode.
High luminous efficiency will reduce heat generation, reducing heat generation can reduce light decay, and higher enchantment temperature will reduce the requirements of heat sink. The choice of high-end chips is a good holiday decorative lamp body. However, a certain treasure cannot buy lamps with United States CREE chips, because it is too expensive, the gap between chips of the same size is about 10-100 times, and the gap between the finished products is even greater.
LED single tube power 0.03~0.06 watts, DC drive, single tube drive voltage 1.5~3.5 volts, current 15~18 mA, fast response speed, can operate at high frequency. In the case of the same lighting effect, the power consumption is 1/10,000 of the incandescent bulb, half of the fluorescent tube, and Japan estimates that if the LED with twice the light efficiency is twice as high as the fluorescent lamp, half of the incandescent lamps and fluorescent lamps in Japan are replaced. This saves the equivalent of 6 billion litres of crude oil per year. 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 varied.
The festival decoration lamp of the festival decoration lighting project adopts electronic light field radiation luminescence, and the filament is easy to burn, thermal deposition, light attenuation and other shortcomings. The LED lamp is small in size, light in weight, and encapsulated in epoxy resin, which can withstand high-intensity mechanical impact and vibration, and is not easy to break. The average life expectancy is 100,000 hours. The service life of the festival 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.
