Description

Variable-focus rotary reading lamp Technical Field The utility model relates to a variable-focus rotary reading lamp, and belongs to the field of vehicle-mounted equipment. Background The reading lamp in the car is the lighting equipment of installing in the car inside (like driver's seat top, the middle top of rear seat or door region), mainly is used for providing local illumination for the passenger, is convenient for read or look for article when night or light are not enough, avoids influencing the driver's sight simultaneously. The illumination lamps and lanterns design that is used often in the current automotive interior is comparatively fixed, is difficult to realize the regulation of light direction and intensity according to the user's demand, mainly has following problem: 1. The light angle is fixed, so that the personalized requirements of different passengers are difficult to meet. 2. The lack of a zooming function is that light rays cannot be freely switched to focus or scatter, so that the diversity of the used scenes is affected. 3. The operation complexity is that the switch design of most vehicle-mounted lamps is inconvenient, and driving or use experience is affected. Disclosure of utility model The utility model aims to overcome the defects and shortcomings in the prior art and provides a variable-focus rotary reading lamp. The utility model provides a rotary reading lamp zooms, includes the base, it is connected with rotary lamp subassembly and LED lamp to rotate on the base, rotary lamp subassembly is including coaxial fixed lens, the removal lens and the track body that sets up, be equipped with the track that is used for removing lens axial reciprocating motion on the track body, it is equipped with the drive division with track terminal surface butt to remove the lens both ends, the axial rotation action of removal lens along the track terminal surface through the drive division drives the focus between removal lens and the fixed lens and produces regular change, and then makes the irradiation area of reading lamp change thereupon. Through the mechanical linkage of the rotary rod and the track body, the rotary action of the lamp cap is directly converted into the axial displacement of the movable lens, and the focal length can be accurately adjusted by single-hand rotation. Compared with the traditional linear push-pull zoom, the rotary operation accords with the ergonomics, the structural compactness is obviously improved, and the installation requirement of a narrow space in a vehicle is better adapted. The direction of the lamp cap is rotationally adjusted, so that the lamp cap is suitable for various use scenes in vehicles, such as reading, atmosphere lighting and the like. Focusing (local illumination) or scattering (large-range illumination) can be switched according to requirements, so that comfort is improved. The combination of the rotary lamp component and the track body makes the system compact in structure, is suitable for various vehicle types, can flexibly adjust layout according to different mounting positions (such as a vehicle roof, a seat side edge, a vehicle door and the like), and enhances the applicability of products.
