1、 The impact of infrared radiation on the autonomic nervous system. The autonomic nervous system mainly regulates visceral function. People are in a state of anxiety for a long time. Persistent nervous system panic can lead to weakened immunity, headaches, dizziness, insomnia, fatigue, and cold limbs. Infrared radiati……

With the rapid development of optoelectronic technology, metal LED beads are becoming the core force in the field of lighting and display due to their excellent performance. Unlike traditional packaged LED chips, metal based LED chips have the advantages of high thermal conductivity, low light decay, and strong stabili……

In today's rapidly advancing technology, infrared emitting LEDs, as a new type of light source, are quietly changing our lives with their unique hidden light wave characteristics. It not only reveals another side of the world of light waves to us, but also plays an irreplaceable role in multiple fields. Infrared emitti……

LED bead packaging technology is mainly developing towards high luminous efficiency, high reliability, high heat dissipation capacity, and thinness. From the perspective of chips, the most common type currently is horizontal chips, while more high-end manufacturers are developing vertical chips and crystal clad chips. ……

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……

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……
