The Next Decade Laser Lighting Will Replace LED Lighting

Laser lighting is a laser as a light source, but not directly to the laser “on the road”, so I am afraid that titanium eyes are really going to be blind. Laser lighting visible light laser lighting and infrared laser lighting.

Visible light laser lighting, according to the principle is divided into the following two: blue light to stimulate the realization of white fluorescent lighting; red, green and blue burning laser pen synthesis of white laser, or true color light. Infrared laser lighting, and more used in night vision, night camera monitoring lighting.

Laser lighting of the two areas of application First, the application of automotive lighting in the automotive industry, the second is as a safety lighting, applied in the riding warning. The development of car lights so far, from the initial just to the current standards of judging more and more, brightness, energy consumption, coping with complex environments and even aesthetic design are as “the eyes of the car” indispensable important indicators The Car lights according to the use of time are: kerosene lamp, acetylene lamp, incandescent lamp, xenon lamp, LED lights, laser headlights.

Whether a lighting technology can be widely used and its own technology research and development progress, the cost level. High-end cars already equipped with LED headlamps, and to start the application of green laser light headlamps, there are some low-end car is still the main halogen bulb, halogen light yellow light in the rain and fog weather penetration. Xenon lamp using the arc discharge to light, compared to halogen yellow light, white people shines, but “high light dog” more use of this lamp, so the security risks are relatively large.

Different lighting technologies have different advantages, and LED lights and laser lights are different from their previous “light” lights series, which can cope with more traffic conditions. Nakamura Shuji believes that, compared to LED, laser lighting has smaller luminous area, higher luminous efficiency, more sensitive focus on the senses and further distance. The laser light of lower energy consumption, the theory of luminous efficiency is 60% higher than the LED lights, such as new green astronomy laser lights equipped with the BMW 7 series, a single lamp group using only the three laser diodes (small volume light system design also provides more possibilities). It also has faster response speed, narrower lighting beam, super penetrating power and lighting distance.

From the irradiation distance, xenon headlamps can reach 150 m, LED headlights up to 300 m, and because of the super laser collection, laser headlamps can reach 600 m. Only when the speed is more than 70 km/h and the ambient light is allowed, the laser light will be automatically lit to avoid the adverse effects of the high beam. Laser lighting system and laser unit as a high beam lamp, which has four most powerful laser diodes, can emit 5500 K color temperature of the strong white light. The speed is up to 60 km/h, and the laser light will automatically turn on, thus greatly enhancing the visual field. Laser light has its limitations, because of the use of the process will produce great heat, how to improve the durability of the radiating lamp lighting system, a single set of lower cost, so as to realize the laser light production, will be the direction of future research.

Laser lighting technology will become a new generation of lighting technology, and its entrance is in the automotive lighting applications. At present, the main task is still technological research and development and results transformation. When the technology is mature and the cost is reduced, laser lighting will be applied in more fields.
