What LED light is equivalent to 100 watts?

The wattage of the lamp determines its power consumption. Let's now talk about the same power consumption of Aluminum 2.0W LED board 100w incandescent lamp and 1 layer LED Based Night Lamp 100w LED lamp? They are all 100w, so their power consumption is equal, the most direct manifestation of this 100w is the manifestation of your electric meter. A 100W incandescent lamp and a 100W LED, if you look at the power alone, the power consumption is the same, but the actual situation is different. Wattage is actually an indicator of power consumption, and the different working modes of LED, what we call light-emitting diodes, increase its work efficiency and increase the utilization rate of electricity, so the consumption of less wattage can also be achieved. The same effect.

The incandescent lamp is an electric light source that energizes and heats the filament to an incandescent state, and emits visible light by using thermal radiation. It was invented by American inventor Thomas Alva Edison in 1879. The LED lamp is a piece of electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver or gold wire, and the surrounding is sealed with epoxy resin to protect the inner core wire. Function, finally install the shell, so the LED lamp has good seismic performance.
The working principles of the two kinds of bulbs are different. The principle of the incandescent lamp is a kind of heat radiation light source, and the energy conversion efficiency is very low. Only 2% to 4% of the electric energy is converted into light that the eyes can feel. However, incandescent lamps have the advantages of good color rendering, continuous spectrum, and convenient use, so they are still widely used. LED principle Light-emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. LED bulbs are the most energy-saving bulbs that can be achieved by science and technology. Nowadays, there is a kind of wheat ear bulbs, which are truly energy-saving bulbs. Depending on the wick, they are a combination of light-emitting transistors welded on the Aluminum LED board. This kind is called LED Bulb. It can be seen that it has very low power consumption and long life span from the fact that it has no heat and no flicker when it works.
Let us now talk about the same power consumption of 100w incandescent lamp and 100w LED lamp? From a physical point of view, the electrical power is the same, so the power consumption is the same, and the power consumption is the power consumed per hour. A 100W bulb means that the power of the bulb is 100 watts. Then the power consumption of a 100W bulb in 1 hour, unless it is a low-quality product, the power rating is not accurate. But LED has high brightness and long life. A 100w incandescent lamp and a 100w LED lamp consume the same power because their rated power is 100w. Incandescent lamps and LED lamps with the same power consume the same amount of power, which is different from the amount of light emitted.
Energy-saving bulbs and incandescent bulbs of the same wattage, at the same time, consume the same electricity, and pay the same electricity bill. However, the brightness of the two points is different, and the brightness of the energy-saving lamp is much higher. Therefore, to achieve the same brightness, you only need to buy energy-saving bulbs that have a much lower wattage than incandescent lamps, and you can save energy and save electricity bills. In other words, you originally needed 100W incandescent lamps under the same brightness requirements. You only need to buy 50W energy-saving lamps to meet your needs. Just pay 50 watts of electricity and enjoy the same brightness. Our pursuit of brightness is getting higher and higher today, and we can't wait to make the night brighter than the daytime. The total power of LED lights used in homes has reached more than 60W. So some people will complain that changing the LED lamp consumes more electricity, because you change the lamp while increasing the power. This is the true meaning of the name of the energy-saving lamp-saving energy and money under the same brightness. Incandescent lamps are easy to break and have a short life span, and energy-saving lamps are not very long.
The incandescent lamp is an earlier lighting fixture. The advantage of this kind of lamp is low cost and no additional power supply is needed when used. The disadvantage is that the light efficiency is short and the life is short. Because it emits light by heat, most of the electric energy is used It has a fever, and its life span is only a few thousand hours. LED is a new type of lighting fixture that appeared after the incandescent lamp. It has the advantages of high light efficiency and long life. Due to the luminous efficiency of incandescent lamps, the production of high-power incandescent lamps is now not allowed, and low-power incandescent lamps are rarely used.
The luminous efficiency of the two kinds of bulbs is different. The incandescent lamp is a heat radiation light source, which emits heat at the same time. The luminous efficiency is about 15%. That is to say, for a 100W incandescent lamp, only about 15W of electric energy is used to emit light, and the rest of the electric energy is all heat; The luminous efficiency of LED lamps can reach 90%. A 100W LED lamp has 90W of electric energy to emit light. This is why LED lamps are much brighter than incandescent lamps with the same power. Needless to say, incandescent lamps, the relatively high temperature of the bulb during operation means that more electrical energy is converted into useless heat. With the same wattage and the same duration of energy-saving lamps and LED lamps, the actual touch is that the temperature of the LED lamps is higher. Could it be that the energy-saving of LED lamps is just a gimmick for manufacturers to promote?
LED lamp is also called cold light source, its conversion rate is very high, the conversion rate is as high as 70-80%, and the conversion rate of incandescent lamp is 10-15%, that is to say, the light emitted by a 20-30W LED lamp can It can keep up with the brightness of a 100W incandescent lamp. Therefore, people use LED lights to achieve the same effect of incandescent lamps, only 1/4 watts is enough, which is to save electricity, commonly known as energy saving. The core of the LED lamp is a light-emitting diode, a solid-state semiconductor device that can directly convert electrical energy into visible light. Unlike other lamps, the white LED lamps used for lighting are emerging products in the 21st century. Compared with the fluorescent lamp camp, they have more significant advantages in energy saving, longevity, environmental protection, earthquake resistance, and stable light emission.

Under the same power, although their power consumption is the same, their luminous brightness is very different. Because of their different luminous efficiency, LED luminous efficiency is much higher than that of incandescent lamps. Under the same power, the luminous brightness of LED lamps is equivalent to 4 1 energy-saving lamps and 10 incandescent lamps. Although the LED light is bright, its illumination angle is relatively small, about 120°, so it can only be bright in a small space; if it deviates from this angle, the light will be greatly reduced. However, the incandescent lamp can emit light almost 360°, and the brightness of the surrounding space is almost the same. The same is 100w, their power consumption is the same under the same working conditions, but the use effect is different. Incandescent lamps have the advantages of good color rendering, small size and low cost, but also have the disadvantages of low optical efficiency and short life. Incandescent lamps and LED lamps have differences in environmental protection, conversion efficiency, light, service life, and usage conditions.
