Illumination table lamp for adjusting eye-protection lamp

Abstract

The invention belongs to the technical field of illumination lamps, and particularly relates to an illumination table lamp for adjusting an eye-protection lamp. The illumination table lamp comprises a rod-shaped lamp holder, a placing base, a height adjusting piece, a pressing switch, a rotating shaft, a lamp shell, an LED lamp tube and an infrared height measurer, wherein the rear side of the bottom of the rod-shaped lamp holder is fixedly mounted at the front end of the placing base, a movable groove is formed in the inner side of the rod-shaped lamp holder in a penetrating mode, and two rheostats are symmetrically and fixedly installed on the inner side of the movable groove. According to the invention, the height of the LED lamp tube can be automatically changed according to different sitting posture heights of different users or the same user at different moments, so that the eyes of the user are prevented from being directly irradiated by the table lamp light source, the optimal height difference between the table lamp light source and the eyes of the user is constantly kept, the illumination brightness of the LED lamp tube can be constantly changed along with the height of the LED lamp tube, the illumination effect on the table top is kept consistent at the optimal light intensity all the time, and the problem that the illumination effect is changed due to the height change of the table lamp is avoided so as to protect the eyesight of the user.

Description

technical field [0001] The invention belongs to the technical field of lighting fixtures, and in particular relates to an illumination table lamp for adjusting an eye protection lamp. Background technique [0002] The eye-protecting desk lamp is mainly used to make people's eyes work and study under the desk lamp for a long time, and the eyes are not easy to get tired. The data design using the optical principle makes the light emitted by the desk lamp more suitable for the eyes to work and study under the light. comfort. [0003] In the prior art, such as Chinese Patent No.: CN 110578880 A "an eye-protecting LED desk lamp", comprising a desk lamp body, a base, a pole, a sliding sleeve, a fixed block, a lamp arm, a mounting frame, a lighting mechanism and a cooling fan , the bottom of the desk lamp body is provided with a base. The structure of the present invention is scientific and reasonable. Through the setting of the sliding sleeve, the height of the lighting mechanism...

Problems solved by technology

[0004] 1. When placing a table lamp, because there are cells in the retina that perceive light and color, these cells are very sensitive. If you look directly at the light source for a long time and over-stimulate the eyes, it will cause damage to the eyes, edema, congestion, and eye problems. Pain and other problems, you need to pay attention to lower the height of the desk lamp and avoid looking directly at the light source. However, due to differences in personal height, different users need to adjust the height of the desk lamp before use, or the same user sits for a long time. It will keep changing, and it is difficult to ensure that the height between the eyes and the desk lamp is always at the optimal height

[0005] 2. After adjusting the height of the table lamp, it will affect the light intensity of the table lamp on the desktop. For example, when the position of the table lamp is raised, the light intensity on the table will be slightly reduced. After the position of the table lamp is lowered, the light intensity on the table will be slightly increased, which cannot be maintained After the height of the table lamp is changed, the best lighting effect on the table does not change. After adjusting the height of the table lamp, it is necessary to continuously adjust the light intensity of the table lamp accordingly, which is time-consuming and laborious.
