LED Lighting – COBs, Engines, Modules

Powerful and efficient LED lighting has revolutionized the modern world and its benefits have been extended to a variety of industries, including automotive, medical, industrial, agricultural, and consumer goods. This article will discuss the 3572 application field and working principle amongst COBs (Chip on Board), engines, and modules that are used in LED lighting.

COBs (Chip on Board):

COBs (Chip on Board) are light emitting diodes that are integrated onto a single circuit board that has multiple chips. This type of lighting is commonly used in residential or industrial production environments, due to its efficiency and low cost. The advantages of COB LED lighting are its higher efficiency, light output enhanced uniformity, and superior optical performance.

The 3572 application field for COBs includes indoor lighting, landscape lighting, stage lighting, billboard lighting, decorative lighting, cabinet lighting, downlight and luxury lamp lighting, among others. It is also used in automotive lighting and signage. In the 3572 application field, COB LED lighting has superior thermal resistance, which allows it to survive in harsher environments like these.

COBs are most commonly used in LED engines and LED modules. The working principle of a COB is simple; the electricity passes through the chip and the light is converted into visible light by its phosphor coating. The light output is directed through secondary optics to focus it into desired patterns.

LED Engines:

LED engines are composed of a single COB, driver and a housing. This combination is used to produce large amounts of high quality light. The 3572 application field for LED engines extends to commercial, industrial, and architectural lighting. This is because they are easily compatible with different housings and design styles.

The working principle of LED engines is simple. The electricity passes through the driver, then to the COB. The driver adjusts the electrical current entering the COB in order to produce the desired amount of light output. The light is then focused through secondary optics to create the desired patterns.

LED Modules:

Finally, LED modules are pre-assembled LED light sources that are designed for installations into housings. These modules can contain multiple LED components and require minimal installation time. LED modules are popular in the 3572 application field due to their long service life, high efficiency and good heat dissipation.

The working principle of LED modules is similar to that of LED engines. Electricity passes through an onboard driver, which adjusts the current to the desired levels for the LED strings contained within the module. The light is then directed towards the housing through a variety of methods such as TIR lenses, reflectors, and diffusers.

LED lighting has revolutionized many industries and the 3572 application field and working principle of LED COBs, engines, and modules have become increasingly important in the development of innovative lighting solutions.
