LED Lighting – COBs, Engines, Modules:

Light emitting diode (LED) lighting has revolutionized the lighting industry by offering superior energy efficiency, superior white light quality and a much longer product life. LED light sources offer the highest efficiency and quality while replacing almost any conventional light source like fluorescent, halogen and incandescent lamps. LED lighting products are available in a variety of form factors, from small lamps and traditional light bulbs to LED components which provide a bare LED light source.

LED Lighting components are available in a variety of configurations, each with unique lighting applications and working principles. Two of the most widely used LED components are COBs (Chip on Board) and LED Engines. Let’s explore how each of these components work and in what applications they should be used.

COBs (Chip on Board)

COB LEDs are composed of multiple LED chips mounted directly onto a single printed circuit board. This allows the multiple chips to be powered and controlled as one single source of light, making it ideal for applications where multiple light sources would be bulky and/or costly. COB LEDs have become the most popular choice for many spot and accent lighting applications due to their simplicity, small size, and powerful light output.

COB LEDs are offered in a wide range of wattage and come in packages that range in size from 3x3mm, 5x5mm, 5x3mm, 7x7mm, 11x11mm, 11x13mm, 13x13mm, 17x17mm and 21x21mm. The LED chips are available in various color temperatures and color rendering indexes (CRI). COB LEDs provide off-axis illumination, typically have lumen-per-watt efficiencies of up to 110 lumen/watt and offer good color consistency with low thermal resistance.

Engines

An LED Engine is an integrated light source that combines an LED package, optics, and a driver into an easy-to-install and connect unit. LED Engines are designed to replace both traditional light sources like bulbs and tubes and more complex lighting systems. LED Engines come in a variety of shapes and sizes to meet the needs of designers. Some are configured as single-source light bars and contain a single COB or multiple COBs mounted in a common housing. Others are configured as multi-source direction light bars and contain multiple, individual COBs mounted in a common housing.

LED Engines are commonly used in downlighting and linear lighting applications because they provide a precise, controlled and well distributed light output. Due to their integrated design, LED Engines also offer simple installation and connection which makes them an ideal choice for many lighting projects. Some LED Engines come with integrated sensors, allowing them to be controlled via Bluetooth or Wi-Fi, making them even more versatile and cost-effective.

Modules

An LED Module is an entire lighting system in one convenient package. LED Modules are great for retrofitting existing lighting fixtures or creating new ones, as they contain all of the necessary components to make a working light fixture. LED Modules usually consist of an LED light source, a driver, and a heat sink. Some LED Modules also include integrated optics and a dimmable LED driver to add additional control and flexibility.

LED Modules are most commonly used for downlighting, track lighting, and spot lighting applications. Their flexibility and modular design make them an ideal choice for any lighting application that needs precise control. LED Modules are available in a range of wattages, color temperatures and color rendering indexes (CRI).

The long life and efficiency of LED light sources has made them the perfect choice for many lighting applications. LED Lighting offers superior white light quality, low energy consumption, and long product life. LED components like COBs, Engines and Modules provide a cost-effective solution for almost any lighting need and come in a variety of sizes and configurations.
