The utility model discloses a LED (Light emitting diode) desk lamp, including the power adapter circuit, the PWM that connect gradually adjust luminance integrated circuit, light source drive circuit and LED quantum dot light source. The utility model discloses when making the led desk lamp have the illumination function, be absorbed in the quality and the adaptation and the matching of human vision system of illumination light, adopt the luminous technique of advance quantum dot, initiatively at desk lamp field introduction LED quantum dot light source, and adjust luminance integrated circuit through PWM and adjust, introduce first the detection & controling of the important optical index of color rendering index (CRI) and this binomial of panchromatic territory index (GAI), and control CRI is between 80% -100%, GAI is between 80% -100%, comfortable healthy illuminating effect has been reached.
