The Light Source Module is a critical subassembly within Optical Scanners that generates and directs specific wavelengths of light onto target surfaces. It ensures consistent, uniform illumination for accurate image capture, barcode reading, or surface inspection by the scanner's optical sensors. The module typically converts electrical energy into light using LEDs, lasers, or halogen lamps. It incorporates optical elements (lenses, diffusers) to shape and focus the light beam, and may include drivers and thermal management systems to maintain stable output intensity and spectral characteristics. This directory entry provides reference specifications for typical industrial modules. The module is designed for integration into scanning equipment, with a compact form factor (dimensions ranging from 30×30×10 mm to 100×100×50 mm) and a weight of 20–200 g. Key parameters include output power (1–10 W), wavelength (405–850 nm), beam angle (10–60°), luminous flux (50–500 lm), color temperature (3000–7000 K), input voltage (12–24 V DC), power consumption (2–15 W), operating temperature (-10 to 50 °C), storage temperature (-20 to 70 °C), IP rating (IP40–IP65 per IEC 60529), and lifetime (20,000–50,000 hours, L70 lumen maintenance). Materials typically include LED/Laser diode, optical-grade plastic/glass, aluminum alloy housing, and copper/PCB for circuitry. These values are reference ranges; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The module's performance directly affects scan accuracy and reliability, making proper selection and verification essential.
The module converts electrical energy into light using LEDs, lasers, or halogen lamps. Optical elements such as lenses and diffusers shape and focus the light beam to achieve the desired beam angle and uniformity. Drivers regulate current to maintain stable output intensity, while thermal management systems dissipate heat to preserve spectral characteristics. The light is directed onto the target surface, and the reflected or transmitted light is captured by the scanner's optical sensors for image formation or analysis.
