QLA764BHGY Application Field and Working Principle

LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs.

QLA764BHGY is a highly reliable LED circuit board indicator commonly used in domestic and international markets. Multipurpose applications include industrial automation, medical instrumentation, retail setting, automotive, etc. With smart and high-performance features like extreme brightness, minimum voltage circuitry, and mounting flexibility, it is an ideal choice for illuminated control indication applications.

QLA764BHGY is composed of two parts, one is the LED and the other is the PC board. LED is the light source, and PC board is the base device. LED is entirely encapsulated with epoxy resin, and covered with silicone. The circuit board is made of phenolic fused silica in order to provide a high-temperature tolerant and long-term reliable quality. It uses SMD technology to ensure the right brightness, luminous purity and viewing angle.

One of the key features of QLA764BHGY is its working principle. The working principle of the LED starts with a voltage differential. The voltage differential creates a field on the back of the LED. Because of the field, radiation pressure on the semiconductor material from the light of the diode releases electrons from the gallium arsenide material, making the electrons enter the anode. The cathode of the system has silver, so that under the consideration of the field, more electrons will move from the back of the diode to the anode, which is full of hole. When electrons and hole join, it releases light energy and generates the light.

QLA764BHGY has a wide range of practical applications, including lighting for domestic and international industrial machines, office automation equipment, electronic pointing devices, vehicle-mounted electronic equipment, wireless communications equipment, display modules, and intelligent lighting. Any device that contains an LED or display screen and needs a circuit board indicator can benefit from QLA764BHGY. For example, it can be used to indicate the status of the machine in an industrial machine, display the information of a communication device, or provide an illuminated wayfinding solution in a retail setting.

In conclusion, QLA764BHGY is a high-performance LED circuit board indicator with smart and reliable features that can be widely used in a wide range of applications. It has a unique working principle, which ensures the right amount of brightness and luminosity. In addition, its high temperature tolerance and long-term reliability make it an ideal choice for illuminated control indication applications.
