Check the listing for details. Osram 3.5W White Laser Light Source Module Double Light lens Automobile Lamp. Condition: New. Listed at 58.28 USD. Properties:Technology core: high-energy laser excitation of fluorescent crystals to produce white light.The luminous intensity reaches 540cd/mm2.10000 hours of service life.No moving elements, high stability, high shock resistance.Low voltage drive, on and off.Full coverage of visible spectrum, no infrared and ultraviolet components.Adjustable brightness, support amplitude modulation and frequency modulation.Original imported laser.High conversion efficiency, lighting 30% higher than market products +Heat dissipation requirement:1. The heat dissipation system only needs to dissipate heat through the heat dissipation surface (see the outline dimension drawing). The temperature of the radiating surface is not higher than 60 ℃.2. The radiator must be in full contact with the thread to ensure that the heat of the light source can be quickly transferred to the radiator.3. If necessary, the radiator needs to be cooled by a fan to ensure that the temperature is not higher than 60 ℃.4. Calorific calculation: calorific value = driving electric power x heating energy ratio = driving electric power x 70%.Driver description.Drive interface: according to the outline dimension drawing, weld the positive and negative leads at the positive and negative electrode welding pad.Driving mode: the laser must be driven by a constant current, using a constant current circuit within 4.3-5V, and ensure that the output voltage-including instantaneous voltage, such as power-on and ripple-does not exceed the maximum voltage at any time. Attention should be paid to prevent electrostatic damage during transport. Taking into account the voltage loss, the maximum voltage can be appropriately increased.
