Lasers, originally named in Chinese as “laser†and “Lyse,†are called LASER in English, meaning “light amplification of stimulated radiation.†The full name of the laser (English name: LightAmplificationbyStimulatedEmissionofRadiation) fully expresses the whole process of manufacturing lasers, 1964. Qian Xuesen, a famous scientist in our country, suggested that “light stimulated emission†be renamed laser.
About LED infrared lamp various characteristics, I believe we all have a very clear familiar, LED infrared night vision lighting there are some limitations such as: irradiation interval, brightness, heat, life, etc., in many areas can no longer meet the security monitoring project The night vision infrared requirements. In order to solve the various limitations of LED infrared light, major manufacturers have also adopted various methods to improve the status quo, although some are to increase the monitoring interval and brightness, increase the number of LED lights and power current, but at the expense of heat dissipation and life . If you do not reform the nature of technology, these topics cannot be fundamentally resolved.
To achieve the monitoring of the COSCO interval, we must adopt new technologies, that is, infrared laser night vision technology. Our Dapu company is currently the largest domestic production base for pump lasers. Laser infrared lamps have been developed to meet the needs of many security companies in night vision technology. , To bring more business opportunities and development to more security companies, it will also lead the development of the night vision industry in the security industry to further deeper and further development. With the laser infrared lamp technology's excellence and development, it will inevitably become a night vision infrared technology. The leading product.
The nature of the laser infrared lamp: The semiconductor laser's electro-optical conversion efficiency is at least 55%. Since we only use a single light-emitting chip, the heat loss is much lower than that of the LED lamp. The choice of the laser wavelength can increase the sensitivity of the CCD to the wavelength. (For example, the 810nm light source is 30% more sensitive to the CCD than the 850nm infrared light. That is, regardless of other factors, the same power of the 810nm laser light is equivalent to the same power multiplied by 2.5 times the 850nm. Infrared lighting effects). The following figure shows the spectral sensitivity curve of SONY ExView CCD.
The most fundamental advantages of laser infrared lamps:
Ø Long-distance irradiation: The interval between conventional product irradiation is 30 to 500 meters and the maximum distance is 3,000 meters.
Ø Brightness: CCD sensor sensitivity to 810nm laser light is 30% higher than that of 850nm LED light.
Ø Long product life: The unique laser power supply temperature control technology enables the internal working temperature of the laser infrared lamp to process a constant working temperature, which ensures the lifetime of the laser infrared product is greatly guaranteed. The actual service life of the Dapu laser infrared lamp products is 8000-10000 hours.
Ø Low product power consumption: The maximum power of the conventional products of the Dapu Laser Infrared Lamp is no more than 20W, which is more in line with China's relevant environmental protection and energy conservation policies for environmental protection and energy conservation.
