Every foreign trade person should know about the 7 segment LED display screen product

Every foreign trade person should know the following examples of 7 segment LED display screen products.

LED, also known as LED, is a solid-state semiconductor device that can directly convert electricity into light. Its heart is a semiconductor chip, one end of which is attached to a bracket, one end is a negative electrode, and the other end is connected to the positive electrode of the power supply, making the entire chip encapsulated in epoxy resin. A semiconductor chip consists of two parts, one is a P-type semiconductor in which holes dominate, and the other is an N-type semiconductor in which electrons dominate. But when these two semiconductors are connected, a P-N junction is formed between them. When an electric current passes through a wire and acts on this chip, electrons are pushed towards the P region, where they recombine with holes and emit energy in the form of photons. This is the principle of LED luminescence. The wavelength of light, also known as the color of light, is determined by the material that forms the P-N junction.

LED lights use semiconductor materials. When current passes through them, they are impacted by electrons within a certain range due to their high energy. At the same time, a reaction occurs over time.

The characteristics of remote controls, TV remote controls, commonly used TV remote controls at home, computer remote controls, etc. determine the functionality and distribution of remote controls.

Light emitting diode (LED) is a kind of commonly used light-emitting device, which emits light through the recombination of electrons and holes. The traditional TV remote controller adopts high-frequency Piezoelectricity processing method. Compared with other traditional TV remote controllers, it can greatly reduce the loss of light source and add new collectors.

The open system in our country is the core of open design concepts and social multimedia automatic control, and the possibility of television expansion and social information address. Open and open market application solutions are the trend of open development.

Home appliances are a rapidly developing social development goal in China. In the context of production in the field of home appliance safety, fully demonstrating the quality of life is truly a way to save electricity in households.

Energy saving: Compared to incandescent lamps and fluorescent lamps, lighting fixtures that save more than 5% energy are better.

High efficiency: compared with ordinary incandescent lamps, as long as the ordinary solid state light source (SSL) is used, a DC constant current source (IF) is added in the glass bulb shell, and then the LED ballast is stabilized through a Pressure regulator.

Commercial lighting is a strategic direction for China's growth, aiming to improve the quality and output of core lighting products and provide better products for global consumers
