LED Lighting COBs, Engines, Modules: LXK8-PW50-0206 application field and working principle

Light-Emitting Diodes (LEDs) can be used for a variety of applications, ranging from signaling to illumination. One of the primary applications for LEDs is in lighting, where they are used for accent, task, and general lighting. To maximize performance and minimize complexity, LEDs are often used in combination with drivers, reflectors, and other components in the form of a module, engine, or chip-on-board (COB). The LXK8-PW50-0206 is an example of a COB used in LED lighting applications.

COBs are generally composed of a PCB substrate containing large numbers of LEDs in an array. The LXK8-PW50-0206 is a high-efficiency COB that includes 298 total LEDs mounted on a 48mm x 48mm ceramic substrate. It is built with 288x 4-series white LEDs, 8 blue LEDs, and 2 orange LEDs, with a CRI rating of up to 93 and a luminous flux of over 2750lm. This COB is designed for operation with an input DC power of 11-18V, resulting in an output of 40W.

The LXK8-PW50-0206 is designed for a variety of LED lighting applications, including commercial lighting, white lighting, indirect lighting, and backlight. It is ideal for use in street lighting, recessed lighting, outdoor lighting, office lighting, and more. The COB is relatively easy to install and offers excellent thermal performance, making it well-suited for applications requiring efficient cooling. This COB offers high performance at an economical price.

The working principle of the LXK8-PW50-0206 involves taking advantage of the electrical characteristics of LEDs. When a current flows through an LED, both a voltage drop across it and a corresponding light emission occur. The current is limited by a resistor in series with the LED, since the LED is essentially a short-circuited device. The voltage across the LED can be controlled by varying the resistor\'s resistance, resulting in different light output intensities. By using an array of LEDs, larger amounts of power and light can be generated.

To use the LXK8-PW50-0206, a power supply and driver circuit must be employed. A microcontroller is typically used to regulate the voltage applied to the LEDs. The power supply is responsible for converting the AC power to the necessary DC voltage levels. A switching mode power supply is recommended to achieve high efficiency. The driver circuit provides the necessary current to the LEDs, allowing them to be driven in parallel with multiple others while ensuring they all receive the same current.

In summary, the LXK8-PW50-0206 is a high-efficiency COB designed for use in LED lighting applications. It combines 288x4-series white LEDs, 8 blue LEDs, and 2 orange LEDs into a single package, resulting in a CRI rating of up to 93 and a luminous flux of over 2750 lm. When used in combination with a power supply, driver circuit, and microcontroller, this COB can provide excellent lighting for applications such as street lighting, recessed lighting, outdoor lighting, office lighting, and more. In addition, it has a relatively simple installation process and offers excellent thermal performance.
