红外线接收管有两种，一种是光电二极管，另一种是光电三极管。光电二极管就是将光信号转化为电信号，光电三极管在将光信号转化为电信号的同时，也把电放逐大了。因而，光电三极管也分为两种，分别是NPN型和PNP型。    在红外线接收管管壳上有一个能射入光线的玻璃透镜，入射光经过透镜正好映照在管芯上。红外接纳二极管管芯是一个具有……

传感器LED灯珠熄灯后发现灯珠微亮如何处置    灯珠微亮阐明断电还是有电流经过的缘由，详细应该是驱动或者输入电的问题        传感器LED灯珠的原理是什么    传感器LED灯珠是应用了人所产生的热红外线辐射。应用灯头局部的人体感应元件，经过圆形的菲涅尔滤光片，将热红外线聚焦于感应元件外表，产生电信号，经过信号……

红外LED灯珠的结构原理是一块电致发光的半导体材料，置于一个有引线的架子上，然后周围用环氧树脂密封，祷告维护内部芯线的作用,所以红外LED灯珠的抗震性能好。        红外LED灯珠光源的特性        1. 电压：红外LED灯珠运用低压电源，供电电压在6-24V之间，依据产品不同而异，所以它是一个比运用高压电……

一、 红外线对自主神经的影响        自主神经系统主要调理内脏功用。人们长期处于焦虑状态。植物神经系统持续慌张会招致免疫力降落、头痛、头晕、失眠、疲倦和四肢发冷。红外线能够调理自主神经使其坚持最佳状态，上述病症能够得到改善或消弭。        二、 红外线对皮肤护理和美容的影响        红外辐射能够共振并……

Light emitting diode (LED) piranha lamp beads are one of many LED packages. The shape is mainly square and packaged with colloidal transparent resin. There are four pins, one LED lamp bead, and one pin is missing from the negative electrode. LED piranha lamp beads are astigmatic LED lamp beads with a luminous angle gre……

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……

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……

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……

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……

LED beads can operate continuously under most different conditions. However, once the LED beads are corroded, they will be subjected to chemical reactions from the surrounding environment, thereby reducing the performance of the LED beads. Avoiding LED bead corrosion is an important step in improving LED bead reliabili……

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. ……

To maintain a long life and high brightness of LED lamp beads, the first issues to be solved are: LED lamp bead power supply, LED lamp bead light source, LED lamp bead heat dissipation, and LED lamp bead safety. 1. LED Bead Power Supply The primary requirement for LED Bead Power Supply is high efficiency. A product wit……
