LED light bars are lighting fixtures that use Light Emitting Diodes (LEDs) to produce bright, energy-efficient lighting. They are typically long, narrow bars with multiple LED bulbs mounted on them, arranged in a linear pattern. LED light strips can be divided into single-color LED light strips and multi-color LED light bars. Monochromatic LED light strips have a variety of colors, such as red, green, blue, etc., and LED light bars with different functions can be customized according to customer needs. The multi-color LED light bar is composed of LEDs with different colors, which can realize multi-color jumping, trendy rainbow and other lighting effects, and is suitable for a variety of lighting scenes. LED light bars are commonly used on vehicles such as trucks, SUVs, and ATVs as auxiliary or off-road lighting, but they can also be used for indoor or outdoor lighting in various applications.
One of the main advantages of LED light bars is their energy efficiency. Compared to traditional incandescent or halogen bulbs, LED bulbs require much less energy to produce the same amount of light, which means they can be used for longer periods of time without draining the battery or putting a strain on the vehicle’s electrical system. Additionally, LED light bars are very durable and can withstand harsh weather conditions, shock, and vibration, making them ideal for use in off-road environments.
LED light bars come in a variety of sizes and configurations, from small, single-row bars to large, multi-row bars. They can be mounted on various parts of the vehicle, such as the roof, bumper, or grille, depending on the user’s needs and preferences. Some LED light bars also come with additional features, such as adjustable brightness, strobe functions, and different color options.
In summary, LED light bars are a popular lighting solution that provide bright, energy-efficient lighting for a variety of applications. They are durable, versatile, and can be easily installed on vehicles or in other environments where additional lighting is needed.
The working principle of LED LIGHT BAR is based on LED (Light Emitting Diode) technology, which transforms electrical energy into visible light. LED LIGHT BAR is composed of many LED lamp beads, and each LED lamp bead is a diode. When the current passes through the LED lamp beads, it will stimulate electrons in semiconductor materials. These electrons will jump from low energy levels to high energy levels, resulting in energy and release of photons. The energy of these photons determines their wavelength and color.
Electronics in LED LIGHT BAR pass through a PN knot, which is a semiconductor structure composed of two different materials. When the electron flows through the PN knot, they will meet and generate energy with the PN knot -knotted acupoints, which stimulates the production of photons. This process is called injection compound. By controlling the selection of currents and materials, LED lamp beads can produce different colors of light, such as white, red, green or blue.
