Description

Eye-protecting desk lamp and light source assembly thereof

Technical Field

The utility model relates to a desk lamp technical field especially relates to an eyeshield desk lamp and light source subassembly thereof.

Background

The light source assembly of the traditional desk lamp with AA-level authentication and AAA-level authentication usually adopts an optical lens or a light guide plate to realize the stretching of light, so that the uniformity is improved, namely, the main light direction is changed through the lens or the light guide plate after the light source emits light, the light-equalizing (art-designing) plate on the outer layer of the mirror is generally simple in design, does not have the function of changing the light path, and only has the function of visual attractiveness. The light source component of the existing desk lamp mainly has the following problems: 1) the weight of the optical lens and the light guide plate is not favorable for the design of the lamp body: the weight of the optical lens is about 40 to 100 g. The light guide plate is generally an optical plate with a thickness of more than 4mm, and the weight of the light guide plate is more than 50 g. When the lever folding type desk lamp is designed, the strength requirements on the rotating shaft, the lamp post and the like are greatly increased through the amplification effect of the force arm. For example, a 150mm long lamp post is adopted, a rotating shaft with the radius of 5mm is used, only the force of the lens part for amplifying the rotating shaft can reach 1.200-3 kilograms, and the strength requirements of the rotating shaft part plastic material and the lamp post can be raised by one grade. 2) The optical lens and the light guide plate themselves are expensive: generally, the cost of an optical lens mold is 2-10 ten thousand yuan, and the unit price is 3-10 yuan. For example, for a desk lamp with 10 thousands of sales, the average cost of the lens part is 5-20 yuan. The cost of laser dotting process cost added to the plate with the thickness of the light guide plate being more than 4mm exceeds 4 yuan. 3) The lens and light guide plate absorb illuminance and color temperature by themselves: no matter the lens made of any material can not achieve the situation that the color temperature and the illumination intensity are not changed when light passes through the lens like air, and the situations of losing the illumination intensity and the color temperature exist.
