LED Lighting - COBs, Engines, Modules

The GW5DGA27M04 is an LED product that falls into the category of COBs (Chip-On-Boards) lighting applications. It is a compact, single-package 5W LED engine that is well-suited for use in general lighting, task lighting, furniture lighting, and decorative lighting. Although this is a single-package product, there are multiple discrete components in its design.

LED Chip

At the heart of the GW5DGA27M04 is a single Cree XP-G2 LED chip. This particular LED chip is designed for use in LED lighting applications, has a high efficacy rating, and low thermal resistance. The LED chip is designed to best dissipate heat, ensure long life, and run efficiently.

Control Circuitry

The GW5DGA27M04 also has a control circuit that contains resistors, a capacitor, and a diode. These components are used to regulate the current supplied to the LED chip and control the light intensity. The control circuit is designed to ensure consistent performance over time and maximize the LED chip’s energy efficiency.

LED Driver

The GW5DGA27M04 is an LED product, but it is not self-powered. Rather, it must be powered by an LED driver. An LED driver is a power supply specifically designed to work with LED lamps. It is designed to provide a constant current and voltage to the LED lamp and ensure that it does not overheat or draw too much current. An LED driver can also help to ensure that the LED lamp gets the best possible performance from its LED chip, resistance, and control circuitry.

Working Principle

LED lighting products, like the GW5DGA27M04, work on the principle of current regulation. When a current is supplied to the GW5DGA27M04, the control circuit regulates the current and the LED chip starts emitting light. The current and voltage supplied to the LED chip are adjusted by the LED driver, which ensures that the LED chip does not overheat. The LED chip is then able to emit the desired amount of light while consuming an optimal amount of energy.

Application Field

As mentioned before, the GW5DGA27M04 is well-suited for applications in general lighting, task lighting, furniture lighting, and decorative lighting. The compact single-package design and high energy efficiency of this product make it a perfect replacement for incandescent lights, as well as ideal for retrofitting existing lighting systems. Additionally, the GW5DGA27M04 can be used for both indoor and outdoor lighting applications.
