According to statistics, if 1/4 of the incandescent bulbs and traditional fluorescent lamps in Taiwan are replaced with white LEDs, about 11 billion kWh of electricity can be saved every year, which is equivalent to the annual power generation of nuclear power plants. Therefore, it will be the main light source for future lighting. , How to improve LED brightness and reduce costs is bound to become a major issue.

The popularity of modern mobile phones, tablet computers and large LED TVs has also made LEDs more commonly used in backlight panels. Because of the invention of blue LED, today's world can be controlled by computers, so that LED emits millions of colors of light. Therefore, everything from large LED display boards and traffic lights that can be seen everywhere on the road to the backlight system of small screens. There are LED figures.

In addition, in modern times, computers are often used to control the intensity and color of LED light to simulate sunlight for greenhouse planting, so we can often see flowers in different seasons at the same time.

12 square meters bedroom led light 30w will it be too bright

12-15w LED lights are suitable for a 12-square-meter room; 30w is definitely too bright. Because LED lights are equivalent to 60-80 times that of ordinary lights, if 10 square meters use 12-15w LED lights, it is equivalent to nearly 100w of ordinary lights, which is bright enough.

1. About 15W is required for 12 square meters of LED lighting.

2. First of all, LED lighting fixtures usually only need half the power of fluorescent lamps to achieve the same lighting effect as fluorescent lamps under the same lighting environment conditions. That's half the money.

3. Secondly, for a room of 12 square meters, if fluorescent lamps are usually used, a circle of about 28W is a ceiling lamp. So if you use LED, it is about 15W. Finally, it depends on the specific installation height, which is generally based on the height of about 3m.
