Becoming an LED packaging enterprise with high core value
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……View Details
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……View Details
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……View Details
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 a……View Details
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……View Details
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……View Details
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……View Details
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……View Details
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……View Details
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……View Details
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. ……View Details
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……View Details
