Eye protecting multi-source desk lamp

Abstract

The invention relates to an eye protecting multi-source desk lamp, which comprises a load bearing base, a main load bearing post, an auxiliary load bearing post, a main illumination lamp head, a sideillumination lamp head, an auxiliary illumination lamp head and a control circuit, wherein the upper end surface, the left end surface and the right end surface of the load bearing base are provided with guide slide rails; the lower end surface of the main load bearing post is glidingly connected with the guide slide rails through the slide rails; the upper end surface and the main illumination lamp head are mutually connected; the lower end surface of the auxiliary load bearing posts are glidingly connected with the side surface guide slide rails of the load bearing base through slide blocks;the auxiliary load bearing posts and the slide blocks are hinged through universal hinges, and are respectively and mutually connected with one side illumination lamp head; an auxiliary illuminationlamp head is embedded in the front side surface of the load bearing base; a control circuit is embedded in the load bearing base. The eye protecting multi-source desk lamp has the advantages that on one hand, the generation of visual fatigue phenomenon due to nonuniform darkness distribution can be effectively avoided; on the other hand, in the illumination process, the illumination range and theillumination angle can be flexibly regulated according to requirements; the illumination flexibility is improved; meanwhile, the shadow region in the illumination range can be effectively reduced or lightened.

Description

technical field [0001] The invention relates to a desk lamp, in particular to an eye-protecting multi-source desk lamp. Background technique [0002] At present, in daily study, life and other activities, it is often necessary to use desk lamps to strengthen lighting of local environments such as rooms or desks to meet the needs of life and study. However, it is found in actual use that the current desk lamp equipment has a lighting Although the light source can meet the needs of lighting, on the one hand, the lighting range is relatively small, and it can often meet the fan-shaped lighting range of 90°-135° with the lighting source as the center, and the maximum range does not exceed 180°. The area is relatively small, resulting in a relatively large difference between the lighting range of the desk lamp and the surrounding environment, which can easily cause visual fatigue and cause eye diseases such as myopia and astigmatism. The human body, books, tools, etc. form a lar...

The area is relatively small, resulting in a relatively large difference between the lighting range of the desk lamp and the surrounding environment, which can easily cause visual fatigue and cause eye diseases such as myopia and astigmatism. The human body, books, tools, etc. form a large shadow area, which seriously affects the lighting effect and has a great impact on daily learning, work and other activities
