Office lamp with automatic brightness adjusting function

Abstract

The invention discloses an office lamp with an automatic brightness adjusting function. The office lamp comprises a human body detector, a timing circuit, a light intensity detecting unit, a parameter input unit, a lifting frame, a lifting driving mechanism, a rotary support seat, a rotary driving mechanism, a brightness adjusting unit, a first data storage unit, a second data storage unit, a third data storage unit and a controller. A plurality of appropriate irradiation parameters corresponding to different age groups are stored in the first data storage unit, corresponding relations among surrounding environment light intensity change conditions and the irradiation parameters required to be adjusted are stored in the second data storage unit, corresponding relations among the duration of desk work and the irradiation parameters required to be adjusted are stored in the third data storage unit, and the controller controls the lifting driving mechanism, the rotary driving mechanism and the brightness adjusting unit. The office lamp with the automatic brightness adjusting function has the advantages that the office lamp is reasonable in circuit design and good in using effect, and brings convenience for wiring and adjusting the parameters, and the parameters such as the irradiation height, an irradiation angle and the irradiation brightness can be automatically and correspondingly adjusted according to the duration of desk work of office staff, the intensity of light of a surrounding environment and the like.

Description

technical field [0001] The invention relates to a brightness self-adjusting office lamp, in particular to a brightness self-adjusting office lamp. Background technique [0002] Improper illumination brightness or illumination angle of lamps will have a considerable adverse effect on the vision problems of office workers. The illumination brightness and illumination angle of the existing desktop office lamps can be adjusted, but most of them can only be adjusted manually. Once the working hours are busy, it is very likely to be neglected. It is determined by personal preference, without any scientific and medical basis, and the adjustment process is more complicated and the adjustment state is not easy to grasp. Therefore, there is a lack of an office lamp with reasonable circuit design, convenient wiring, convenient parameter adjustment and good use effect, which can automatically adjust the irradiation height and irradiation angle according to the office staff's desk work ...

[0002] Improper illumination brightness or illumination angle of lamps and lanterns will have a considerable adverse effect on the vision problems of office workers

The illumination brightness and illumination angle of the existing desktop office lamps can be adjusted, but most of them can only be adjusted manually. Once the working hours are busy, it is very likely to be neglected. It is determined by personal preference, without any scientific and medical basis, and the adjustment process is more complicated and the adjustment state is not easy to grasp

Therefore, there is a lack of an office lamp with reasonable circuit design, convenient wiring, convenient parameter adjustment and good use effect, which can automatically adjust the irradiation height and irradiation angle according to the office staff's desk work time, the intensity of surrounding ambient light, etc. Adjust accordingly with parameters such as illumination brightness
