With the development of the times, from ordinary lamps to various types of lamps, downlights are also very common in modern home decoration, not only with decorative effects but also very artistic. So what are the downlight sizes? Op downlight prices and installation precautions? Let's learn about it with the editor!There are many downlight sizes, and different brands have different sizes. The editor below has compiled a small list of downlight sizes for your reference.Downlight power Produc
About LED light strips: This is the true face of LED light strips; just like straps, plus the use of LED light sources (the LED light source will not be explained too much), to put it bluntly, it is called LED light strips , Immediately connect to the voltage of 38OV, it will be bright, fixed with a fixed card, it will not be too difficult to use, LED lights with red, yellow, blue, green, white, warm light and other visible light, also have colorful change. Generally, warm white lights are used
Compared with other building decoration materials, LED light strips are relatively softer than traditional light sources and have the following advantages: they are softer and can be bent. It can be cut and connected. Its light bulb and power circuit are completely enclosed in soft plastic, the insulating layer has good moisture-proof characteristics, and the application is very safe. The weather adaptability is relatively strong, not so easy to crack, the application life is relatively long, it
The control and interaction of the light pole LED electronic screen has realized an intelligent upgrade. Judging from the current level of intelligence of industry products, it has entered a new stage of "intelligent interconnection". Along with the boom of the smart and interactive LED electronic screen market, a wave of smart interconnected products has been triggered, let us see that the industry has undergone a subtle change in nature, and we believe that a new era of smart display
In what direction will the light pole LED display develop? From the light pole LED display industry, it can be easily concluded that the development of an industry needs time to settle, and it needs a good policy environment. Although my country's economy is currently in depression and the growth rate of economic development is slowing down, with the continuous development of the industry, new economic growth is still continuously improving, and it is becoming more objective yea
The photodiode is a semiconductor device composed of a PN junction. The depletion layer of the PN junction is only a few microns, and most of the irradiated light is absorbed by the neutral region, so the photoelectric conversion efficiency is low and the response speed is slow. In order to improve the characteristics of the device, a layer of intrinsic semiconductor (called |) is arranged in the middle of the PN junction. This structure is a commonly used PIN photodiode. PIN photodiode improv
According to different photoelectric switch manufacturers, the classification of various photoelectric switches adopts different standards and classification methods, representing different attribute categories. Some of the classification methods between them are cross, and the photoelectric switch will not pass the classification method at the time of purchase. Simplify, integrate and use multiple levels of corresponding options. 1. Classification by detection method One is the light quanti

1. Features of photoresistor type: The internal photoelectric effect has nothing to do with the electrode (the photodiode is related), that is, DC power can be used; the sensitivity is related to the semiconductor material and the wavelength of the incident light; it exists in the form of a photoresistor, and the resistance of the resistor is very high when no light is received. When there is light stimulation, the resistance value decreases with the change of light intensity; epoxy resin enca
What tests do qualified direct-plug LED lamp beads need to go through? Now, let’s take a closer look with the editor of the infrared pair tube manufacturer. 1. Optical and electrical performance test; forward voltage drop, reverse current; luminous flux, spectrum, color temperature, CRI and luminous angle. 2. Lens: Identify the type of encapsulation glue and detect whether there are contaminants and bubbles. 3, phosphor coating; phosphor particle size, particle size distribution, composition
(1) Night vision When the visibility is low and the light is insufficient, infrared rays are used for night vision equipment. When the night vision device is working, it will actively illuminate the target and then use the target to reflect the infrared light of the infrared source to implement the night vision technology of observation. This corresponding device is a night vision device. (2) Thermal imaging uses the infrared radiation emitted by the infrared emission tube to reach the tar
