MB403-A28AC-CW - Application Field and Working Principle

LEDs are becoming increasingly popular as the ideal lighting solution for many application fields. They are more efficient and last far longer than traditional incandescent lamps, and they offer higher color rendering while consuming less energy. The MB403-A28AC-CW is a high-brightness LED (known as “COB”) that is suitable for many different applications such as general lighting and sign/indicator lighting. It features excellent luminous efficiency and low thermal resistance, allowing it to be used easily in a wide range of lighting designs.

The working principle of the MB403-A28AC-CW is based on the physical phenomena of the “electroluminescence”. This is the phenomenon in which electrical energy is converted into light energy. When electricity is supplied to the LED, electrons move from one PCB to another. This flow of electrons creates an electric field inside the LED. This electric field in turn induces the emission of photons, which are light particles.

The LED consists of a few main components,the LED chip itself, a PCB, and a driver. The LED chip is the component that emits light. It is typically composed of a semiconductor material, like silicon, that is surrounded by metal contacts. The PCB is the component that provides electrical connections to the LED chip, and the driver is the component that provides power to the LED. The driver is typically a switched-mode type, and it is specially designed to provide the LED with the necessary power.

The MB403-A28AC-CW LED is capable of producing a wide range of colors and brightness. It is available in various emission levels and is capable of producing excellent color rendering indexes (CRI). This makes it ideal for many applications ranging from general illumination to signage lighting. It has a long life expectancy, and its excellent thermal characteristics make it suitable for extended periods of use in enclosed spaces. Due to its high efficiency, it can reduce energy costs significantly, particularly in applications where the LED will be switched on for long periods of time.

Overall, MB403-A28AC-CW is a high-brightness LED that is ideal for many different types of lighting applications. It offers excellent luminous efficiency, low thermal resistance, and long-life expectancy. Its wide range of color options and its excellent color rendering make it perfect for both general illumination and signage lighting. Lastly, its energy efficiency will save energy costs significantly, making it ideal for many applications where the LED will be used over long periods of time.
