High Power White Laser Module for Lighting Source

This laser module uses a high-power blue laser to convert it into white light, which has high brightness and good stability. It is cheaper than traditional white lasers and is ideal for use as a lighting source. Installation is simple - you can refer to the instructions.

Key Features
• Technical core: high-energy blue laser excites fluorescent crystals to produce white light.
• The optical power is 3.5W, and the luminous intensity reaches 540cd/mm2.
• The useful life is up to 10,000 hours.
• It has no moving parts, with high stability and high shock resistance.
• It is driven by low voltage, with good stability.
• With full coverage of the visible spectrum, no IR or UV components.
• The brightness is adjustable, with amplitude modulation and frequency modulation.

Requirements of heat dissipation
1) The radiator must be in good contact with the thread to ensure that the heat of the light source can be quickly conducted to the radiator.
2) If necessary, the radiator needs to be cooled by a fan to ensure that the temperature is not higher than 60 °C.
3) Calculation of calorific value: calorific value = driving electric power x heating energy ratio = driving electric power x 70%.

Instructions for use
1) Drive interface: You can weld the positive and negative leads at the positive and negative pads.
2) Driving mode: The laser must be driven by a constant current mode, using a constant current circuit within 4.3-5V, and ensure that the output voltage at any time (including the instantaneous voltage) does not exceed the maximum voltage. Please pay attention to prevent electrostatic damage during transportation. Due to the voltage loss, the maximum voltage can be appropriately increased.
