Classification of energy-saving lamps and definition of energy-saving lamps
The official name of energy-saving lamps is rare earth tricolor compact fluorescent lamps, which were born in Philips in the Netherlands in the 1970s. Under the premise of achieving the same light energy output, this light source only needs to consume 1/5 to 1/4 of the electricity consumption of ordinary incandescent lamps, and the luminous efficiency is 50 lumens/watt, which can save a lot of lighting energy and costs, so it is widely used. called energy-saving lamps. That is to say, the light efficiency of more than 50 lumens / watt can be called energy-saving lamps.
(1) Metal halide lamp
The metal halide lamp has a color rendering index of over 80, a luminous efficacy of over 75 lumens/watt, and a color temperature of 6000K. The advantages are long life, high light efficiency, good color rendering, and obvious power saving effect. It is the fourth generation light source in the world today.
(2) The efficiency of high-voltage nano-lamps reaches 90~100 lumens/watt, which is 2 times and 7 times higher than that of mercury lamps and incandescent lamps, respectively. The color rendering index is 60, the ultraviolet component is less, it does not attract insects, and the illuminated object does not fade, and the color temperature is only 2100K.
(3) The self-ballasted fluorescent light effect is above 60 lumens/watt, which is 4 times higher than that of ordinary incandescent light, and the life span is more than 8000 hours.
(4) Compared with double-ended fluorescent lamps (thin diameter), the lifespan is extended by 20%, the light efficiency is increased by 22%, the energy saving is 10%, and the lifespan can reach 10,000 hours above.
(5) Compared with the 40-watt, 20-watt electronic ballast and the magnetic ballast, the power consumption can be saved by 5 watts and 3 watts respectively. The ballast can save 20 kWh of electricity per year, and a 40-watt electronic ballast can save 60 degrees of electricity per year. In addition, the voltage can be started as low as 130 volts.
(6) led light
LED light is a new light source with a color rendering index of over 90, a light efficiency of 110 lumens/watt, and a color temperature of 4000-6000K. Advantages Long service life (more than 50,000 hours), 80% energy saving, environmental protection (no UV stroboscopic and no heavy metals), and good color rendering. It is the latest light source in the world today.
