The HLG-40H-24B is an LED driver designed specifically for indoor lighting applications including but not limited to ceiling lights, wall lights, desk lamps, and pendants. The HLG-40H-24B uses high-efficiency, long-life LEDs as its optical source.

The HLG-40H-24B LED driver has a wide range of output current options ranging from 0.5A to 4A, and provides flicker-free lighting with constant current operation. It has a wide input voltage range from 90VAC to 305VAC and accepts single phase AC input current with a operating frequency of 47-63Hz. It provides power factor correction of 0.98 and is capable of achieving 99% power efficiency over its full load range. The driver is also equipped with thermal, over-voltage protection as well as a no-load protection circuit and has an expected lifetime of up to 100,000 hours.

The working principles of the HLG-40H-24B LED driver are based on the high-frequency switching principle and consist of a two-stage power supply. The first stage is a boost diode with fast response and high efficiency, which ensures that the output voltage of the LED driver comply with the characteristics of the LEDs, while the second stage is a Buck converter which provides short-circuit protection, over-voltage protection, over-temperature protection, and other safety function. The two-stage power supply is then combined with a controller to ensure the LED driver can meet the needs of various lighting applications.

The application fields of the HLG-40H-24B LED driver include both commercial and residential lighting applications such as office buildings, airports, exhibition halls, shopping malls, supermarkets, residential lobbies, corridors, and more. This wide range of applications is due to its high power factor, wide input voltage range, excellent power efficiency, and universal compatibility with LED lighting fixtures. The LED driver is also well suited for both retrofit and new installations.

The HLG-40H-24B LED driver is a reliable, cost-effective, and energy-efficient solution for indoor lighting applications. With its advanced protection circuit, wide input voltage range, and power factor correction of up to 0.98, it is an ideal choice of LED driver for indoor lighting applications. Furthermore, its expected lifetime of up to 100,000 hours makes it a great choice for both short-term and long-term installations.
