Abstract

The invention discloses a desk lamp. A lighting lamp body of the desk lamp comprises a casing, a first light source and a rotating disc are arranged in the casing, a plurality of optical filters in different colors are embedded on the rotating disc, light emitted by the first light source is transmitted out from the optical filters in the different colors to change colors irradiated through the first light source, and the light in different colors can be selected according to learning contents. A sensing light adjustment control unit for switching a power supply switch and adjusting luminance of the first light source is arranged in the lamp body of the desk lamp, a touch sensing face is arranged on the outer casing of a base, and the luminance of the first light source can be adjusted through the touch sensing face. Color changing and color matching of the desk lamp can be carried out according to the learning contents, and learning efficiency is improved. The desk lamp has functions of automatically switching between a small night lamp and a reading distance reminder, the small night lamp can light while sleeping, has the function of attracting attention and brings convenience to users to determine the position of the desk lamp, the reading distance reminder can prevent myopia, and functions of the desk lamp is comprehensive.

Description

technical field [0001] The invention relates to a desk lamp, in particular to a multifunctional desk lamp with adjustable illumination color. Background technique [0002] Desk lamp is one of the lighting fixtures commonly used by people. Desk lamp is also a lighting tool for students to study at night. It is scientifically pointed out that "the human brain has different learning effects according to the color temperature and illuminance", so different colors of light have different learning effects. Learning efficiency can be improved by choosing the appropriate lighting color to match the learning content. Existing desk lamps that can change the color of light, such as the patent No. 200910038224.0, the invention patent of perceptually adjustable LED desk lamps, use a plurality of red LEDs, green LEDs, blue LEDs and white LEDs with adjustable color temperature and color volume as light sources. The PWM control signal sent by the external part is used to process the increa...
