The main technical terms of electronic energy-saving lamps are: model, working voltage, wattage, lamp head, color temperature, lumens, lamp, light decay, plastic, life, etc. The following one explains.
Everyone in the supermarket can generally see 2u series, 3U series and other energy-saving lamps. What does this mean? Everyone knows that the lamp of the energy-saving lamp is U-shaped, 2 lamps are 2U, and 3 lamps are 3U. There are no major differences between other lamps of different shapes. The main difference is the power. Generally, the larger the wattage, the longer the length, and the thicker the lamp and plastic.
Working voltage voltage, the unit is V:
Refers to the voltage required for energy-saving lamps to work. Usually, 220V in our country and most countries in Asia (except Japan and Korea), 230V in Europe, 240V in Australia, North America (USA), Japan (Korea) and most of them. The South American home is 110V, and DC (DC) 12V, mainly for use on board or solar energy. In addition to the voltage, the power supply also has a frequency requirement, and the general frequency is 50 Hz or 60 Hz. But the frequency has little to do with energy-saving lamps. Under normal circumstances, the energy-saving lamp can work normally within the range of -20%--+10% of the working voltage, such as 220V, then calculate according to this ratio as: 176V-242V voltage normal operation, thus avoiding some countries because of voltage instability The resulting large number of energy-saving lamps broke down. One thing to declare is that the more stable the power supply, the longer the service life; the fewer the number of switches, the longer the life.
Power Wattage in W:
Power has two concepts of actual power and print power. The printing power is usually seen by everyone, and most customers can accept the concept; but the actual power is invisible and can only be measured by the instrument, in order to prevent Unscrupulous manufacturers falsify and pretend to use high power at low power to save money (usually the lower the power, the cheaper the price). China has issued a national standard for energy-saving lamps, GB/T17263-2002, which stipulates that the actual power should not be lower than 85% of the printing power. However, due to different commodity inspection requirements in different cities in China, the phenomenon of posing high power with low power is still widespread.
