For the lighting this piece, we more or less also want to understand some knowledge, because it plays a decorative role in the home, including at night when used to play a really large role, so here we have to look at the led light is what meaning, what use, because up to now, there are a few people do not know what its use is, in addition, What is the relationship of led lights.
What do lead lights mean?
LED lamp is an electroluminescent semiconductor material chip, which is solidified on the bracket with silver or white glue, then connected to the chip and circuit board with silver or gold wire, sealed around with epoxy resin to protect the internal core wire, and finally installed the shell, so the LED lamp has excellent seismic performance.
Used as a household lamp. Numerous leads can be used to replace spiraling or saving bulbs, ranging from 5-40 watts, low power, to 60 watts. Some lamps can even replace higher-powered bulbs, such as a 13-watt bulb with the luminosity of a 100-watt incandescent lamp. LED bulbs are also available in different colors and varieties, such as sk6812 rgb led strip manufacturer, but with lower power and maintenance costs.
led lamp relationship
It is well known that the wavelength of the visible spectrum ranges from 380nm to 760nm. It is the seven colors of light that the human eye perceives -- red, orange, yellow, green, cyan, blue and purple, but each of these seven colors is a single color of light. Red light from leads, for example, has a peak wavelength of 565nm. There is no white light in the visible spectrum, because white light is not a monochromatic light, but a composite light composed of multiple monochromatic lights, just as sunlight is a white light composed of seven monochromatic lights, and white light in color television is also composed of the three primary colors of red, green, and blue.
Thus, for an LED to emit white light, its spectral properties should include the entire visible spectrum. However, it is impossible to manufacture LED with such performance under technological conditions. According to people's research on visible light, the white light that human eyes can see needs at least two kinds of light mixed, that is, two wavelength light (blue light + yellow light) or three wavelength light (blue light + green light + red light) mode.
Both modes of white light need blue light, so the uptake of blue light has become the key technology for white light manufacturing, that is, the current "blue light technology" pursued by major LED manufacturing companies. There are only a few manufacturers that master "blue light technology" in the world, so there will be a process to popularize white LED, especially peak brightness white LED in our country.
From the introduction of this article, we mainly look at the meaning of led lamp, what is used, the article tells you, led lamp is a piece of electroluminescent semiconductor material chip, with silver glue or white glue solidified on the bracket, and then connected with silver spot gold wire chip can be used, typically it is used as a household lamp, at this time, You have also learned how the relationship between led lights is.
