GB/T 24907-20 10 performance requirements of LED lamps for road lighting.
Performance requirements of self-ballasted LED lamps for general lighting
Features of LED lamp:
1, saving energy. The energy consumption of white LED is only110 of incandescent lamp and14 of energy-saving lamp.
2, long life. The service life can reach more than 65438+ 10,000 hours, which can be described as "once and for all" for ordinary household lighting.
It can work at high speed. If the filament of energy-saving lamp is switched on and off frequently, it will turn black and break quickly, which is safer.
4. Solid-state packaging belongs to the type of cold light source. Therefore, it is very convenient to transport and install, and can be installed in any miniature and closed equipment, without fear of vibration and basically without considering heat dissipation.
5.led technology is changing with each passing day, the luminous efficiency is making an amazing breakthrough, and the price is also decreasing. The era of white LED entering the home is rapidly coming.
6, environmental protection, no harmful substances containing mercury. The assembly parts of LED bulbs can be easily disassembled and assembled, and can be recycled by others without recycling by manufacturers.
7. Light distribution technology expands LED point light source into surface light source, increases luminous surface, eliminates glare, sublimates visual effect and eliminates visual fatigue;
8. Integrated design of lens and lampshade. The lens has focusing and protection functions at the same time, which avoids the repeated waste of light and makes the product more concise and beautiful;
9. High-power led planar cluster package, integrated design of radiator and lamp holder. It fully guarantees the heat dissipation requirements and service life of led, fundamentally meets the arbitrary design of LED lamps' structure and shape, and has the distinctive characteristics of LED lamps.
10, saving energy significantly. Using ultra-bright high-power led light source and high-efficiency power supply, it saves more than 80% electricity compared with traditional incandescent lamps, and the brightness is 10 times that of incandescent lamps with the same power;
1 1, with a long service life of more than 50,000 hours, which is more than 50 times that of the traditional tungsten lamp. LED adopts advanced packaging technology with high reliability-* * crystal bonding, which fully guarantees the long life of LED;
12, no stroboscopic. Pure DC operation eliminates the visual fatigue caused by stroboscopic light source.
13, environmental protection. No lead, mercury and other polluting elements, no pollution to the environment;
14, impact resistance, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, no damage problem of traditional lamp tube, no harm to human body and no radiation.
15, low hot pressing, safe and reliable. Surface temperature ≤60℃ (when ambient temperature Ta=25℃);
16, wide voltage range, universal LED lamp. Constant current in the full voltage range of 85V~ 264VAC ensures that life and brightness are not affected by voltage fluctuation;
17, adopting PWM constant current technology, with high efficiency, low fever and high constant current precision;
18, which reduces the line loss and has no pollution to the power grid. Power factor ≥0.9, harmonic distortion ≤20%, EMI in line with global indicators, reducing power loss of power supply lines and avoiding high-frequency interference pollution to power grids;
19, universal standard lamp holder, which can directly replace existing halogen lamps, incandescent lamps and fluorescent lamps;
20. The luminous visual efficiency can be as high as 80lm/w, and the color temperature of various LED lamps is optional, with high color rendering index and good color rendering;
Obviously, as long as the cost of led lamps decreases with the continuous progress of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps.
The country pays more and more attention to lighting energy saving and environmental protection, and has been vigorously promoting the use of LED lights.
