How does the LED lamp save power? What is the principle of LED power saving?

When it comes to LED lights, we are not unfamiliar. Now the streets are full of LED lighting. How to save energy of LED lights, LED lights have the advantages of low working voltage, low energy consumption, low radiation, light weight, etc., which are trusted and supported by consumers. How to save energy by LED lights, what is the power saving? What is the principle of electricity. LED light How to save power with LED lights How to save energy in LED lights, LED lights have more power, the most important thing is to look at the light effect, the unit is LM / W, this parameter refers to how bright 1 watt can be. Know what is the use of this parameter? The example will be better understood, the height of the ceiling in the family room or office is about 2-3 meters, about 70-90 lumens can illuminate 1 square (we take the median 80LM), assuming 30 squares Space, you need 2400 lumens to get to our standards too. Well, 2400LM is our requirement, so we can directly use the light effect to calculate how many W lamps need to be illuminated. How to save power of LED lights, the current LED light efficiency is 100LM / w or more, high lumens can reach 150LM / W, we temporarily take the intermediate value of 120LM / W, calculate the use of LED lights need 20W (120 * 20 = 2400). The light efficiency of ordinary energy-saving lamps is generally 45LM/W. It takes 53W (53*45 is equal to 2400) to use ordinary energy-saving lamps. The above thinks that 20W LED lamps=53W energy-saving lamps. Do you understand how LED lights save power? What is the principle of LED power saving? LED is a kind of semiconductor that can convert electrical energy into visible light. It changes the principle of incandescent tungsten light emission and energy-saving lamp three-base toner illumination, and uses electric field illumination, what is the principle of LED power saving. 1. Because LED uses solid semiconductor chips as luminescent materials, and the bulbs used in daily life use luminescent materials, the energy emitted is different. According to relevant statistics, a red LED illuminates to somewhere. The energy required for brightness is 15 watts, while traditional bulbs consume up to 150 watts of energy to achieve the same amount of measurement; LED light 2. According to scientists, when the LED is powered on, 10 electric energy can be converted into light energy, and the conversion efficiency of the incandescent bulb is only 7-8. It can be seen that to achieve the same lighting effect, the LED lamp is more than the incandescent lamp. Energy savings are obvious. According to analysis, the characteristics of LED are very obvious, long life, high luminous efficiency, no radiation and low power consumption. 3. The spectrum of LEDs is almost entirely concentrated in the visible light band, and its luminous efficiency can exceed 150 lm/W (2010). Comparing LED with ordinary incandescent lamp, spiral energy-saving lamp and T5 trichromatic fluorescent lamp, the results show that the luminous efficiency of ordinary incandescent lamp is 12lm/W, the life is less than 2000 hours, the luminous efficiency of spiral energy-saving lamp is 60lm/W, and the service life is less than 8000 hours, T5 fluorescent lamp is 96lm / W, life expectancy is about 10000 hours, and white light LED with a diameter of 5 mm can exceed 150lm / W, life can be more than 100000 hours.
ZF120A Power: Sales of small power Led Power Supply increased
ZH Power said that in 2020, the focus will be on expanding the low-power LED Power Supply market. The low-power LED power supply will achieve 10 million sales last year. This year's sales will reach more than 20 million, which means that sales of low-power LED power will increase. Doubled. Low-power Led Power Supplies are generally used in conjunction with indoor LED lights. The company has planned to release some small-power LED power supply capacity this year, but there is no clear target yet. This year, it will focus on the production of low-power LED power supply. In the company's total business, high-power LED power supply accounts for a large proportion, while low-power LED power supply is relatively small, because the indoor LED lamp price is relatively cheap, the low-power LED power supply gross margin is relatively low compared to the high-power LED power supply.
