Generally, there are 0.06W, 0.5W, 1W, 3W, 5W, etc. according to a single LED lamp bead. Low power LED lamp beads: Low power (such as 5mm straw hat, 5mm spotlight, 3528 package, etc.), 0.06W. Medium power LED lamp beads: (such as 8mm straw hat shape, 10mm straw hat shape, 5050 package, etc.) 0.2W-0.5W. Compared to low-p……

There are two types of infrared receivers: photodiodes and phototransistors. Photodiodes convert light signals into electrical signals, while phototransistors also amplify electrical signals. Therefore, phototransistors are also divided into two types, namely NPN type and PNP type. There is a glass lens on the shell of……

Inline LED is actually an energy-saving and environmentally friendly material that can convert electrical energy into visible light. It is also known as a light emitting diode. The in-line LED consists of a bracket, silver glue, and gold wire. Gold wire is responsible for adhesion and conductivity, and plays a key role……

First of all, let's take a look at the characteristics of LED lamp beads. The angle of LED lamp beads is very small, the light is relatively concentrated, and the range is far, but the irradiation range is limited. LED patches generally have a large angle, light scattering, and a wide exposure range, but the range is r……

In 2026, as Industry 4.0 and intelligent healthcare accelerate their implementation, metal infrared LEDs (TO-CAN packaging) have become the "hidden champions" in fields such as UV sterilization, infrared sensing, and medical equipment, thanks to their three core advantages of airtightness, strong heat dissipa……

In the rapid development of modern technology, metal infrared LED, as a highly reliable light source, is widely used in various fields such as industry, healthcare, and security. Among numerous enterprises, Shenzhen Tianshi Optoelectronics Technology Co., Ltd. (referred to as "Tianshi Optoelectronics") has be……

The reason why LED lamps consume electricity and have a short lifespan is actually due to improper usage habits. The service life of an LED lamp is about 100000 hours, which is about ten years (365 days a year, 24 hours a day, 8760 hours a year, 100000 hours is about 11 years). So why did the LED lights we used break d……

How to deal with the slight brightness of the LED light bead after turning off the sensor? Explain whether there is a power outage or a current passing through the LED light bead. Specifically, it should be a problem with the driving or input power. What is the principle of the sensor LED light bead? The sensor LED lig……

In today's constantly evolving lighting technology, plug-in LED beads are gradually becoming the new favorite of the lighting market due to their advantages of high efficiency, energy saving, long lifespan, and rich colors. They are like small magic beads, bringing light to our lives and opening a new chapter in smart ……

一、散热与寿命：谁扛得住“高温烤验”？    车灯工作环境极其恶劣：发动舱高温、连续照明、振动冲击。    实操建议：优先选用四引脚封装：相比传统两引脚封装，散热面积大、焊接牢靠、抗振性强（通过10–2000Hz振动测试）。    关注热阻参数：选择热阻低于8℃/W的灯珠，能有效抑制高温下的颜色偏移。    二、亮度与……

There are various types and specifications of LED lamp beads: There are too many types of LED lamp beads, including in-line and chip mounted, as well as high-power lamp beads. The current of the lamp beads ranges from tens of milliamperes to a few amperes, and the voltage is relatively consistent, most of which are at ……

Inline lamp beads can also be called plug-in lamp beads, the professional name is plug-in LED. The in-line lamp beads are packaged with epoxy adhesive, chips, and diffusion plates (used for color changing). When transparent, the colloid is colorless and transparent, with luminous angles of 30, 45, 60, and 90 degrees. W……
