Introduction

The CHM-27-40-90-36-AA00-F2-3 is a high power LED engine developed and manufactured by Cree. It is well-known as a pre-manufactured light source module that is used in a wide variety of lighting solutions. CHM is an abbreviation for Cree High Power Modules, which is an international LED modules family launched by the company in 2016. It is the first LED engine module of its kind, featuring a remarkably high efficiency, extraordinary luminous flux and low thermal resistance. The major highlight of the module is its ability to provide industrially leading luminous flux densities without compromising the quality of the light beam. This article will discuss the application field and working principle of the CHM-27-40-90-36-AA00-F2-3 LED engine.

Application Field of CHM-27-40-90-36-AA00-F2-3

The CHM LED engine is primarily used for LED lighting solutions, both indoors and outdoors. It is capable of producing high quality lighting levels to meet both residential and commercial requirements. It is suitable for applications including exterior lighting, industrial lighting and commercial lighting solutions.The engine is ideal for outdoor lighting applications due to its high luminous flux density and wide beam angle. It is capable of producing luminous flux levels of up to 137 lm/W. The beam angle of the module is also wide enough to provide adequate illumination to large outdoor spaces, making it suitable for floodlights, wall washers and other outdoor lighting solutions. The module is also suitable for interior lighting applications. It is capable of delivering high guidelines of light to improve ambiance in indoor and enclosed spaces. Additionally, it produces remarkably low levels of light pollution, which makes it well-suited for residential applications.

Working Principle of CHM-27-40-90-36-AA00-F2-3

The working principle of the CHM LED engine is fairly simple and straightforward. It employs a highly efficient constant power controller to regulate the current input to the module. As such, the engine does not require any change in current, voltage or frequency to produce the desired lighting levels.The working of the controller is based on the principle of PWM (Pulse Width Modulation) controlled drivers. It works by converting the AC line voltage input to the DC voltage which is then regulated through pulse width modulation by varying the duty cycle of the pulses. The duty cycle is determined by the engine\'s initial power setting.Additionally, the engine features an integrated thermal protection system that protects the module from overheating and helps it to maintain a constant temperature. This thermal protection system works by monitoring the internal temperature of the module and adjusting the duty cycle of the PWM input based on that data.

Conclusion

The CHM-27-40-90-36-AA00-F2-3 is an impressive LED engine module from Cree. It features a high level of efficiency, a wide range of luminous flux densities, and a wide beam angle. This makes it ideal for both outdoor and indoor lighting applications. The module also has a sophisticated thermal protection system and a highly efficient constant power controller to regulate the current input to the module. All these features make the CHM LED engine one of the most reliable LED lighting solutions on the market.
