Since Edison invented the electric light, lighting technology has gone through incandescent lamps, fluorescent lamps, and LEDs, and is now moving towards the era of laser lighting. Laser lights are becoming increasingly popular due to their advantages in directionality, beam quality, electro-optical conversion efficiency, and long lifespan. These characteristics give lasers a natural advantage in specific lighting scenarios.
Long-Distance Illumination
The directionality and high-quality beam of laser light sources allow them to easily couple hundreds of watts of optical power into fibers with diameters of only a few hundred micrometers. This feature enables lasers to achieve long-distance night vision security lighting in scenarios such as railways, highways, coastlines, borders, and oil fields. For example, many highways have installed laser stage lights to ensure that drivers can clearly see road conditions at night, effectively improving driving safety. In border surveillance, laser lights can be used to identify unusual activities at night, enhancing security.
Usage Cases
Laser lights
On certain highways in some countries, laser lights are installed along the roadside for illumination and safety monitoring. Drivers can clearly see the road conditions at night thanks to the laser lights, reducing traffic accidents. Additionally, in oil field areas, laser stage lighting outdoor is used for nighttime inspections and safety patrols to ensure the safety of personnel.
Compact and Flexible Structure
Semiconductor lasers are compact with concentrated heat sources, and their electro-optical conversion efficiency is higher than that of LEDs, resulting in lower heat generation at the same power levels. The laser spots outputted through fibers are uniform and symmetrical, with small divergence angles, simplifying optical lens design. This design simplicity allows lighting equipment to be widely used in stage performances and urban landscape lighting, enhancing visual effects.
Usage Cases
Laser lights
In stage performances, laser stage lighting can be easily arranged in various shapes through fibers, creating stunning lighting effects. At a renowned music festival, concert lights combined with laser equipment created dazzling visual effects that attracted a large audience. Additionally, in urban nightscape lighting, laser lights are used for projecting onto building exteriors, making cityscapes more enchanting.
Long Lifespan
Both semiconductor lasers and LEDs are semiconductor devices, and their actual lifespan is affected by factors such as packaging cleanliness and operating temperature. Compared to LEDs, the packaging environment of LDs is cleaner, and they are sealed with dry air, effectively isolating against pollutants. Moreover, LDs have higher electro-optical conversion efficiency, producing less heat, which allows laser fixtures to utilize advanced temperature control technologies to extend their lifespan.
Applications of Different Wavelengths
525nm Green Light: Green light is the wavelength to which the human eye is most sensitive, commonly used for laser dazzling, urban landscape lighting, and stage lights. During festive celebrations, cities use green laser lights to illuminate significant buildings, creating a vibrant atmosphere.
638nm Red Light: Red laser light is commonly used in indicator lights, machine vision, and medical applications. In medical fields, red lasers are used for precise operations in laser surgery, ensuring safety and accuracy.
RGB White Light: RGB laser source technology combines red, green, and blue primary colors, offering a wide color gamut, long lifespan, and high beam quality. This technology is commonly used in laser displays and projections, enhancing visual effects, suitable for large events and stage performances, such as those at Stone Mountain Park.
Usage Cases
Laser lights
In large events, RGB laser fixtures are often used for live performances, creating a colorful visual experience. For instance, at a music festival, laser stage lighting synchronized with the rhythm of the music provides an immersive experience for the audience. Additionally, in laser shows, RGB lasers can create complex patterns and animations, leaving a lasting impression on viewers.
