LED Lighting - COBs, Engines, Modules

A typical LED lighting solution often consists of a combination of chip on board (COB) LED, LED module or LED engine and LED driver. The LED driver is typically responsible for providing a constant current or constant voltage to the load, which in this case is a LED. The LED itself consists of the emitter – the chip on the board that emits the light – and the optics that are used to change the light characteristics of the emitted light.

BXRC-27E1000-C-73

The BXRC-27E1000-C-73 from Broadcom Limited is a COB LED lighting solution designed for high power applications such as flood lighting and street lighting. It uses an LED technology based on Gallium Nitride on Silicon Carbide (GaN-on-SiC) which allows for more light output for a given energy input, meaning the device can be driven at lower voltages and achieve higher light intensity.

Application Field

The BXRC-27E1000-C-73 is ideal for outdoor lighting applications such as street or area lighting, or high intensity general illumination in indoor areas. It is also suitable for industrial and automotive applications such as headlights, taillights and general purpose interior lighting. The device can be driven at lower voltages, meaning that it is particularly suitable for use in applications where the existing power supply may be limited, and where higher efficiency is desirable.

Working Principle

The BXRC-27E1000-C-73 produces white light by combining blue light emitted from one or two integrated emitters and yellow light emitted from a separate phosphor layer. The blue light from the GaN-on-SiC device is converted to yellow light by the phosphor layer, and the combination of the two produces the desired white light. Single emitters can be driven up to 700mA for higher light intensity, or dual emitters can be driven up to 350mA for a lower current level with a more even distribution.

The device is designed for use in conjunction with appropriate LED drivers. It is typically connected to the output of the driver by means of a wired connection, or an interface such as a RJ-45 connector. The LED driver provides a precise current output to ensure that the LED is optimally driven, and to avoid any damage due to over current or over voltage.

In summary, the BXRC-27E1000-C-73 is a high power COB LED lighting solution that is ideal for outdoor and industrial applications such as flood and street lighting, automotive applications such as headlights or taillights, and general purpose interior lighting. It is designed to be driven with an appropriate LED driver and is connected via a wired or interface connection.
