LED backlight rigid bars are light strips assembled with PCB rigid boards and assembled with SMD LEDs or in-line LEDs. Different components are used according to different needs. The LED backlight rigid bar is easier to fix, and it is more convenient to process and install, but it cannot be bent at will and is not suitable for irregular places.
This passage is going to talk about the followings of the technologies used in the LED backlight rigid bar:
1. Working principle of LED backlight rigid bar
2. Technical advantages of LED backlight rigid bar
3. Features and advantages of LED backlight rigid bar
How does the lighting LED light work? The following is some of the simple LED light working principles.
LED backlight rigid bars use basic LEDs as components in LED lighting. When the current limiting voltage is applied to the diode along the forward conduction direction, the light emitting diode emits light. Their diodes must operate under the correct voltage and current conditions-they don't like overvoltage and therefore must limit current. Similarly, they don't like to generate a reverse bias at a certain small voltage.
The operating voltage of a standard white LED is usually in the range of 3 to 3.6 volts. Although this makes LEDs easy to use in devices such as low-voltage circuits and mobile phones, the voltage provided by lamps is much higher, usually 240 or 120 volts, and they are also alternating current AC. As a result, a conversion circuit is required to convert the AC line voltage into a form that can drive a single LED.
For household LED lighting, cost is an important driving factor, so all circuits must be kept at an absolute minimum. This means that the LED bulb contains only absolutely critical circuits.
LED backlight rigid bar lighting differs from incandescent and fluorescent lamps in several ways. If designed properly, LED lighting will be more efficient, versatile and last longer.
LEDs are "directional" light sources, which means they emit light in a specific direction, while incandescent lamps and CFLs emit light and heat in all directions. This means that LEDs can use light and energy more efficiently in a variety of applications. However, this also means that complex engineering techniques are required to produce LED bulbs that can emit light in all directions.
Common LED colors include amber, red, green and blue. In order to produce white light, LEDs of different colors are combined together or covered with a phosphor material that converts the color of light into the familiar "white" light used in homes. Phosphor is a yellowish material that covers some LEDs. Colored LEDs are widely used as signal lights and indicator lights, such as the power button on a computer.
Incandescent bulbs use electricity to heat a wire until it becomes "white" hot or is called an incandescent lamp. As a result, the incandescent bulb releases 90% of its energy as heat.
LED backlight rigid bar, which using high-quality high-brightness as the light source, have low power consumption, no heat, bright colors, and a longer life.
DC24V DC input, IC constant current drive, energy saving more than 70%.
The use of high-transmittance PC cover, high color rendering index, restore the true color of the article.
The inside of the LED backlight rigid bar is potted with high heat dissipation glue, and the power cord is waterproofed to quickly dissipate heat.
It has a wide range of applications, and the corresponding LED strips can be used indoors and outdoors.
Installation and construction are convenient, but the disadvantage is that the LED backlight rigid bar cannot be bent at will.
LED backlight rigid bar does not contain harmful environmental substances, has a long service life, is energy-saving and environmentally friendly.
