一、850nm 与 940nm 金属红外发射接收管选型要点                采购金属红外对管，首先区分两个主流波长的应用差异，再匹配接收管类型（PD 光电二极管 / PT 光电三极管）：                            850nm 金属发射管发光效率高，存在轻微红暴红点；硅基接收器件……

一、金属封装红外传感器，为什么适合车载与机器人场景                车载环境温差跨度极大（-40℃~105℃），伴随发动机震动、车内湿气、油污；移动机器人需要面对粉尘、高低温循环、户外阳光直射，普通塑封红外灯珠容易出现水汽侵入、硫化失效、光衰加速、波长漂移等问题深圳市天实...。             ……

一、宠物用品对红外发射管的特殊要求                宠物智能设备使用环境比较复杂，不同于普通家电，对红外发射管有几个硬性指标：                            检测精准，收发配对一致性高：喂食器粮位、饮水机水位依靠红外对射 / 反射检测，发射管和接收管光谱必须匹配，否则容易出现误报、……

It is believed that almost everyone has encountered a situation where patch LED lamp beads leak electricity, but the reasons for the leakage vary. Some SMD LED lamp beads leak due to testing after packaging, some due to long-term storage, some due to aging, and some due to welding. 1. The stress generated by the leakag……

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……

The structural principle of infrared LED beads is an electroluminescent semiconductor material, placed on a lead frame, and then sealed with epoxy resin around it to maintain the function of the internal core wire. Therefore, the seismic performance of infrared LED beads is good. Characteristics of Infrared LED Bead Li……

一、紫外 LED 只是其中一环，不能独立完成全部鉴伪            紫外（UVA，典型 365nm）LED 核心作用是荧光检测：                            检测钞票纸张是否含有荧光增白剂，假钞常用普通木浆纸，紫外下会泛白；                            激发钞……

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……
