Description

technical field [0001] The invention relates to an eye-protecting desk lamp with automatic color temperature adjustment, which belongs to the field of household appliances. Background technique [0002] Desk lamp is a necessary lighting tool for learning work. Now, desk lamps have developed from the original incandescent lamps to energy-saving lamps and LED lamps, and the focus has also shifted from energy saving to protecting eyesight. Invention patents 201310602154.3 and 201510913620.9 both provide a desk lamp that automatically adjusts the lighting brightness according to the ambient light intensity, but under the same illuminance, the color of the reading material is different, giving people a different visual experience. For example, light-colored reading materials have a high reflectance of incident light, which is irritating to the eyes and is easy to make people tired; while dark-colored reading materials have a high absorption rate of incident light, and less light...
