H178CGDL

LEDs, or light-emitting diodes, are small, but remarkably efficient semiconductor components that convert electricity into light. When a current is passed through, electrons in the semiconductor diode recombine with holes, releasing energy in the form of photons visible as light. This process is known as electroluminescence.

Circuit board indicators are LEDs mounted directly onto a circuit board and used to indicate current flow, temperature, or other information. They are widely used in both industrial and consumer electronics. LEDs come in a variety of shapes, sizes and colours, making them ideal for a wide range of uses, including signalling, as indicators, or as backlighting for LCD displays.

LED arrays are groups of LEDs arranged in specific configurations, usually in lines or columns. Commonly used in backlighting applications, they allow for more even illumination than a single LED might provide. Multiple arrays can be used in tandem to further enhance light distribution, and combined with dimming controls to create more dynamic effects.

Light bars are long, continuous strips of light using multiple, individual LEDs and are commonly used in automotive lighting and signage. For extra brightness and uniformity, multiple light bars are often connected in parallel.

Bar graphs use a series of LEDs to display an analog value, such as temperature, on a scale. Their linear shape makes them easy to read and interpret, and a combination of colours can be used for data separation and high definition displays. LED bar graphs can be found in many places, from industrial applications and laboratory equipment to automotive dashboards and home appliances.

H178CGDL is a type of LED array. It is an embedded LED unit that features a constant-current LED driver and a 25 x 4mm array of SMD LEDs that can be used in combination with modern microcontroller systems and PC-based applications. It has a built-in current limiting resistor and support for up to 1000 candela photosensitivity, making it ideal for a wide range of applications, such as lighting up a product display or providing a backlight for a liquid crystal display.

The LED array of H178CGDL works on the principle of passing an electric current through it. When the current passes through the LED array, the electrons recombine with holes, releasing energy in the form of photons visible as light. The light emitted is proportional to the current being supplied. The amount of current is regulated by the built-in current limiting resistor, ensuring that the array does not overheat and is used safely.

H178CGDL LED array is primarily used in lighting applications that require backlighting, such as LCD displays and automotive displays. It is also used for illumination products and displays, such as in retail stores, museums, and museums. It offers great flexibility in terms of the colours and brightness that can be generated, allowing the user to customise the light output for the desired effect.
