A high-voltage (HV) LED is a DC-driven LED with a turn-on voltage greater than 20V, which is significantly higher than the 2-3V turn-on voltage of conventional LEDs. Typically, a series of small LED cells are electrically connected to form an HV-LED chip.
The Global Blue High Voltage LED Chip market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Osram Improves Efficiency of Blue LED Chips by Reducing Forward Voltage. The forward voltage for blue high-current chips that Osram Opto Semiconductors has attained is among the best in the world. Efficiency has gone up by up to 8% as a result of this.
The foundation for blue or white LEDs is an optimized InGaN chip (Indium-Gallium-Nitride), which uses UX:3 chip technology. Also, according to Osram scientists, there is a lot of room to cut the value by another 20 to 30 mV, which would increase efficiency even more.
The blue Osram Oslon Square (LD CQAR), for instance, now has the lowest usual values in this component class globally, with a normal forward voltage of just 2.87 volts (V) as opposed to the 3.05 V formerly stated in the data sheet.
A voltage of 2.78 V can be reached in the component at 85° C. Depending on the operating temperature, this results in a six to eight percent improvement in the efficiency of these light-emitting diodes (LEDs), which is applicable to the entire UX:3 chip family. All white and blue LEDs contain these chips.
The Osram Oslon Square, for instance, uses LEDs for both industrial and street illumination. The LEDs are employed in a very diverse range of applications.
