High luminous efficiency:
Comparison of luminous efficiency: incandescent, halogen light efficiency of 12-24 lumens / watt, fluorescent lamp 50-70 lumens / watt, sodium 90-120 lm / watt, most of the power into heat loss.
LED luminous efficiency: up to 100-200 lumens / watt, and luminous monochromatic, narrow spectrum, no filtering, can be issued directly colored visible light.
Light utilization: incandescent, halogen, fluorescent, sodium lamp due to the size and shape constraints, light angle is too large, itself also blocks the light, the utilization of light is 40-70%, while the LED small size, production When adding a scattering agent to control the light angle, light utilization up to 90%.
Low power consumption (energy saving): LED DC drive, single-tube drive voltage 1.5-3.5 volts, fast response, reduce startup and preheat power loss, due to the luminous efficiency and light utilization, used in the same lighting effects Case, the power consumption is about one-tenth of the incandescent, fluorescent tube about one-half.
Long service life: incandescent lamp, halogen lamp is the filament heat radiation light source, filament light easy to burn; fluorescent lamp, metal halide lamp is the use of electronic light field radiation, heat deposition, light attenuation and other characteristics, the general life of 1000-5000 hours ; And LED is a semiconductor component, the life expectancy of other semiconductor components, the average life expectancy of 100,000 hours, so the life of LED lamps up to 5-10 years (24 hours light), can greatly reduce the cost of lighting maintenance, to avoid frequent change The light of the pain.
Safe and reliable: Incandescent lamps, fluorescent lamps, halogen lamps and other lamp housing are glass, direct use of high voltage, large size, weight, can not withstand high-intensity mechanical shock and vibration, the use of high temperature, there are security risks. The LED light weight, epoxy package, can withstand high-intensity mechanical shock and vibration, the use of low-voltage DC power supply, the use of low temperature, safe and reliable.
Light source is stable: incandescent lamp, halogen lamp is the use of filament heat radiation source; fluorescent lamp, metal halide lamp is the use of electronic light field radiation, are susceptible to the impact of electricity, luminescence is unstable, and some lamps also need to preheat, temperature Too low can not be started, the light source is unstable, there are different levels of strobe, the eye is relatively large damage, likely to cause eye myopia.
LED switching power supply is generally constant current drive, good monochromatic light, narrow spectrum, no filtering, can be issued directly visible light, will not harm the eyes, will not be affected by electricity, and in low temperature environment can be Use, brightness is not affected by the temperature.
Incandescent lamps, fluorescent lamps, halogen lamps and other lamp damage produce mercury, sodium and other harmful substances, not easy to recycle, LED solid-state light, impact resistance is not broken, no pollution, waste recyclable. Because LED energy-saving, extensive use of LED lighting can greatly reduce the emissions of sulfur dioxide, nitrogen oxides and other harmful gases, as well as carbon dioxide and other greenhouse gases, which will help improve people's living environment, LED is the real "green light source."
