Ushio Inc. has announced the launch of a record-breaking red laser diode, HL63653TG, for compact projectors, levellers, and laser modules. The new 200 mW laser diode delivers the world’s highest output power for the 640 nm wavelength class, while remaining compact in a 3.8 mm package.
The demand for small projectors, such as pico projectors and other types of portable projectors, is growing thanks to the increasing demand for small, mobile electronic devices. Both LEDs and laser diodes are suitable options for the light source in these tiny projectors. In particular, laser-based pico projectors have advantages over LED-driven devices, such as higher luminance and a wider colour gamut, and due to the lack of light dispersion, laser projectors are focus-free.
Currently, Ushio’s laser diodes offer the highest output power, smallest packages, and performance features, such as high reliability and high power conversion efficiency*1. Furthermore, Ushio’s laser diode engineers have been able to concentrate on creating a product that facilitates further downsizing, weight reduction, and lowering power consumption of small, often battery-powered projectors. With this background, Ushio developed and commercialised the HL63653TG, which achieves 200 mW optical output at a wavelength of 640 nm, while maintaining the existing small 3.8 mm package.
Features of record-breaking HL63653TG 640 nm laser diode
- Increased optical output power: from 120 mW to 200 mW (Tc = 25°C)
- Increased efficiency: 6-point improvement in power conversion efficiency (26% to 32%), contributing to lower power consumption
- High-temperature operational optical output power: 90 mW increased to 120 mW (Tc = 60°C)
- High-beam quality: Aspect ratio improved by 21%, contributing to improved efficiency of beam intake into the optical system
As a lighting solutions company, Ushio will continue to provide the components that remain vital to entertainment forms enjoyed by people through visual imaging and lighting technologies.
