Check the listing for details. 1pc white laser light 3.5W laser light source module auto headlight accessories. Condition: New. Listed at 59.85 USD. 1pc white laser light 3.5W laser light source module auto headlight accessories Usage: Adopting inorganic phosphor technology for laser TV with kilowatt level. Transform blue light into white light, no breakdown risk, safe and reliable. Can be used in car lights, flashlights, stage lights, gun lights, drones and other markets. Warm tips: laser products, please do a good job of electrostatic protection to prevent damage. This must be added with a suitable radiator, otherwise the life will be very short, may be burned out after one use, please order again if you understand this product and know how to install the radiator, thank you! The beam in the video is the effect of light after adding a lens, without a lens spot is just a big white spot, please choose the right lens, the operating voltage should be controlled within 4.7V, please know, thank you! Characteristics: Technical core: high-energy laser excitation fluorescent crystals to produce white light Luminous intensity of 540cd2 10000 hours service life No moving parts, high stability, high shock resistance Low-voltage drive, instant on/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 is 30%+ higher than market products Heat dissipation requirements 1. The heat dissipation system only needs to dissipate heat through the heat dissipation surface (see the labeling in the external dimension drawing). The temperature of the heat sink surface is not higher than 60℃. 2. The heat sink must be in full contact with the threads to ensure that the heat of the light source can be quickly conducted to the heat sink. 3. If necessary, the radiator needs to add a fan cooling to ensure that the temperature is not higher than 60 ℃. 4. Calculation of Heat Generation: Heat Generation = Driving Electric Power x Heating Energy Ratio = Driving Electric Power x 70%. Driving instructions Drive interface: according to the outline dimensions of the drawing labeled, in the positive and negative pads, welding positive and negative leads. Driving method: The laser must be driven by constant current, using a constant current circuit within the 4.3-5V voltage, and ensure that the output voltage at any time - including instantaneous voltage, such as the power-up moment and ripple moment - does not exceed the maximum voltage in the Care should be taken to prevent electrostatic damage during transit. Considering the voltage loss, the maximum voltage can be increased appropriately. Package: 1pc white laser light 3.5W laser light source module car headlight accessories
