Several U-tubes are like a straight tube. The more U-tubes, the longer the tube, the greater the luminous flux, and the greater the brightness per unit area. 2U is less powerful than 3U, and no 3U is on. More energy efficient than 3U. Energy-saving l...
(1) Incandescent lamp is also called electric bulb. Its working principle is that heat is generated when the current passes through the filament (tungsten wire, melting point is more than 3000 degrees Celsius). The spiral filament continuously collec...
What are the advantages of LED lights: 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: life expectancy of up to 100,000 hours or more, for ordinary home l...
We generally say that the energy-saving lamps are actually a kind of fluorescent lamps. They are the same as the original fluorescent tubes. They all need electronic ballasts to heat the filaments to more than one thousand K. The filaments radiate el...
Compared with energy-saving lamps, LEDs are more energy efficient. The energy consumed by LEDs is 25 percent of energy-saving lamps. This is because ordinary energy-saving lamps still consume a portion of the electrical energy and convert it into hea...
The first is to look at the brightness \ depends on the color. Does not meet your requirements. The second is better than the brightness. The method is compared with the ordinary energy-saving lamps, that is to say, the LED lamps that you are sat...
The energy-saving products we are talking about today are mainly for incandescent lamps. Ordinary incandescent lighting effects are about 10 lumens per watt, and the life expectancy is about 1000 hours. Its working principle is: when the lamp is conn...
(1) Long life: The so-called life refers to the accumulated time of a finished lamp from ignition to "burning" or lamp operation to any requirement below the life performance specified in the standard. A typical incandescent bulb has a rated life of ...
