The LED Light Module is a self-contained illumination unit designed specifically for integration into Smart LED Desk Lamps. It provides controlled light output with adjustable brightness and color temperature capabilities. The module converts electrical energy into visible light through semiconductor electroluminescence in LED chips, with integrated driver circuitry regulating current and voltage for stable operation. Key materials include LED chips, PCB substrate, thermal interface material, and optical diffuser. The module is characterized by several parameters: luminous flux ranges from 100 to 200 lm/W (IES LM-79), color temperature from 2700 to 6500 K (ANSI C78.377), color rendering index from 80 to 95 Ra (CIE 13.3), input voltage from 100 to 277 V AC (IEC 62386), power consumption from 10 to 50 W (IEC 62301), operating temperature from -40 to 85 °C (IEC 60068-2-1), ingress protection from IP54 to IP67 (IEC 60529), beam angle from 15 to 120 degrees (IES LM-79), lifetime from 50000 to 100000 hours (IES LM-80), dimensions from 50×50 to 300×300 mm, weight from 50 to 500 g, and thermal resistance from 0.5 to 2.0 K/W (IEC 61788-6). These values are reference ranges for directory purposes; actual model-specific values must be confirmed with the legal manufacturer or supplier. The module is intended for use in desk lamps, and its performance should be verified against the listed standards for procurement. The module's design allows for integration into various lamp housings, with considerations for thermal management and optical performance. The module does not include the lamp housing, power cord, or control interface; these are part of the final product. The module's driver circuitry is designed to operate with standard AC mains voltage, but the actual input range should be verified for the specific model. The module's optical diffuser ensures uniform light distribution, but the beam angle can be customized for different applications. The module's lifetime is based on L70 lumen maintenance, meaning the light output will decline to 70% of initial after the specified hours. The module's thermal resistance is critical for heat dissipation; proper heat sinking is required to maintain performance and longevity. The module's ingress protection rating indicates its resistance to dust and water, but the actual rating depends on the enclosure design. The module's dimensions and weight are typical for the specified power range, but custom sizes are available. The module's color temperature and CRI are selectable for different lighting ambiances, and high CRI ensures accurate color rendering. The module's power consumption depends on the size and brightness, and the input voltage range is universal for global use. The module's operating temperature range is extended for outdoor applications, but the actual range should be confirmed. The module's standards are procurement references, not proof of certification. Always verify model-specific values and standards with the legal manufacturer or supplier.
The LED Light Module operates on the principle of electroluminescence, where electrical energy is converted into visible light within semiconductor LED chips. When a forward voltage is applied, electrons recombine with holes in the semiconductor material, releasing energy as photons. The integrated driver circuitry regulates the current and voltage supplied to the LED chips, ensuring stable operation and preventing damage from voltage fluctuations. The driver also enables dimming and color temperature adjustment by modulating the current or using pulse-width modulation. The optical diffuser spreads the emitted light to achieve a desired beam angle and uniformity. Thermal management is handled through the PCB substrate and thermal interface material, which conduct heat away from the chips to a heat sink. The module's design ensures efficient light output with high luminous efficacy, as indicated by the luminous flux range. The working principle is consistent across the specified parameters, but actual performance depends on the specific model and operating conditions.
