The larger market for LED bulb lighting is the civilian market, and the citizens use more spherical bulbs, so LED bulbs are a new type of green light source that replaces traditional incandescent bulbs, because people are accustomed to bulb-shaped bulbs. In order to make the fourth-generation green lighting source better, the shape of this replacement incandescent bulb also adopts a spherical design. The characteristics of LED bulbs: 1. Energy saving, the energy consumption of white LEDs is only 1/10 of that of incandescent lamps and 1/4 of energy-saving lamps; 2. Longevity, lifespan can reach more than 100,000 hours, which can be described as " Once and for all". 3. It can work at high speed. If the energy-saving lamp is frequently started or turned off, the filament will turn black and quickly break down. 4. Solid-state packaging, which belongs to the type of cold light source. So it is very convenient to transport and install, and can be installed in any miniature and enclosed equipment without fear of vibration. 5. LED technology is advancing with each passing day, its luminous efficiency is making amazing breakthroughs, and the price is constantly decreasing. The era of white LEDs entering the home is rapidly approaching. 6. Environmental protection, no harmful substances of mercury. The assembly parts of the LED bulb can be easily disassembled, and can be recycled by others without recycling by the manufacturer. 7. The light distribution technology expands the LED point light source into a surface light source, increases the light-emitting surface, eliminates glare, sublimates the visual effect, and eliminates visual fatigue; 8. The integrated design of lens and lampshade. The lens has the functions of concentrating and protecting at the same time, avoiding repeated waste of light, making the product more concise and beautiful; 9. High-power LED flat cluster packaging, and integrated design of radiator and lamp holder. It fully guarantees the LED heat dissipation requirements and service life, fundamentally meets the arbitrary design of the structure and shape of the LED lamp, and has the distinctive characteristics of the LED lamp; 10. Significant energy saving. Using ultra-bright and high-power LED light source, with high-efficiency power supply, it can save more than 80% of electricity than traditional incandescent lamps, and the brightness is 10 times that of incandescent lamps under the same power; 11. Ultra-long life of more than 50,000 hours, which is the traditional tungsten filament lamp More than 50 times. The LED adopts a highly reliable advanced packaging process-eutectic welding, which fully guarantees the long life of the LED; 12. No flicker. Pure DC work eliminates visual fatigue caused by traditional light source strobe; 13. Green and environmental protection. It does not contain lead, mercury and other polluting elements, and has no pollution to the environment; 14. Impact resistance, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. There is no filament and glass shell, no traditional lamp tube chipping problem, no harm to the human body, no radiation. 15. Work under low thermal voltage, safe and reliable. Surface temperature ≤60℃ (when ambient temperature Ta=25℃); 16. Wide voltage range, universal. 85V~264VAC full voltage range and constant current, to ensure that the life and brightness are not affected by voltage fluctuations; 17. The PWM constant current technology is adopted, which has high efficiency, low heat and high constant current accuracy; 18. Reduces line losses and does not pollute the power grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%, EMI conforms to global indicators, reduces the power loss of power supply lines and avoids high-frequency interference and pollution to the power grid; 19. General standard lamp holders can directly replace existing halogen lamps, incandescent Lamps, fluorescent lamps; 20. The luminous efficiency can be as high as 90 Lm/w, a variety of color temperatures are available, and the color rendering index is generally 0.76-0.85.
