Teach you to write the title of a DIP LED product called "sloping ground"? It's not that troublesome, so it's not that annoying.
Hello everyone, today the editor will teach you how to use the advantages of AB strategy to conduct on-site evaluation. The advertisements I am introducing here, my friends suggest that you recommend adding them in these areas of use.
Nowadays, many shopping malls advertise at subway stations. But for some people, I don't think advertising is that accurate. I think the advertisement is so exciting, using a visual optical engine that can display the content on the wall in real time and cannot be removed.
With the development of cities nowadays, there are more and more subway stations. The subway station is a major component of the subway branch, so what are the forms of subway stations? Let's introduce it to you below.
LED lamp bead is a commonly used light-emitting device. Their luminescence principle is to pass current through compound semiconductors, and through the combination of electrons and holes, excess energy will be released in the form of light, achieving the effect of luminescence. It will appear in its form,
There are many types of LED light sources, and the internal structure of different LED lights may also have slight differences in the light beads used. Today, the editor will comprehensively and systematically popularize science for everyone.
Hello everyone, today we will talk about common LED light sources. LED light source, also known as semiconductor PN junction, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of an LED is a semiconductor chip, one end of which is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, making the entire chip encapsulated in epoxy resin.
With the development of LED in recent years and gradually replacing the original incandescent and fluorescent lamps, it has become an energy-saving lamp, and has advantages such as long service life, small size, light weight, maintenance free, efficient energy conservation, and high reliability. It has gradually gained the benefits of replacing traditional incandescent and fluorescent lamps.
Although traditional incandescent lamps are small in size, they have theoretical knowledge and practical experience, making them an important component of human lighting
