Description

Technical Field

[0001] The utility model relates to the technical field of downlights, and in particular to a downlight capable of automatically adjusting illumination. Background Art

[0002] With the development of science and technology, people's demand for a better life is increasing. In museums and art galleries, exhibits are displayed under the premise of protection. Relevant designs are made by professional lighting designers, and professional data is used as a basis for lighting effects and product selection. Then, they are maintained by a professional management team, which can play the role of safe lighting. However, for private collections, since most of them do not have professional lighting designers and operation management teams, the lighting devices used are likely to affect the lighting safety of private collections.

[0003] A common lighting safety problem is that the lighting intensity is too high, which in turn causes irreparable damage to calligraphy and paintings, painted paintings, and silk fabrics. In the prior art, track spotlights are often used to set the lighting of collections. Although track spotlights can meet the relevant functional requirements of different exhibits for lighting, due to the structure of track spotlights, when they are set on the ceiling, they are easy to protrude from the ceiling, and the visual experience is suppressed due to the height of the private house. At the same time, the space gives the impression of a public museum or art gallery, and cannot effectively meet the lighting needs of private collections. Therefore, it is of great significance to study how to improve the intelligence of lighting settings of lamps so as to meet the needs of different collections and different scenes.

[0004] In patent CN108426206A, an angle adjustment and focusing mechanism of a light source in a downlight is mentioned, and its structure includes: a lamp housing, a heat sink, a lamp board, a movable lamp body, a rotating ring, a lens and a rotating seat are arranged in the lamp housing, the lens is movably arranged in the movable lamp body, the movable lamp body is movably arranged in the rotating ring, the rotating ring is arranged in the rotating seat, a fixed ring is arranged on the lamp housing, both sides of the rotating ring are symmetrically hinged on the fixed ring, at least two spiral grooves are arranged on the side of the movable lamp body, a pair of guide bosses are symmetrically arranged on the bottom of the movable lamp body, and the rotating seat includes: a face ring and an inner and outer cylinder arranged on the face ring, at least two clamping bosses and a spiral protrusion corresponding to the spiral groove are arranged on the inner wall of the inner cylinder in a circumferential direction; a pair of telescopic guide grooves are symmetrically opened on both sides of the rotating ring, and a pair of guide bosses on the movable lamp body are movably arranged on the telescopic guide grooves on the corresponding side, which can be applied to various downlights to achieve angle adjustment and focusing of different downlights, but it cannot solve the problem of lighting intelligence of the lighting device, and cannot achieve automatic adjustment of the illumination.

[0005] In addition, patent CN111425798A discloses an automatic focusing LED lamp with a horizontal focusing structure and a vertical focusing mechanism. However, it is obvious that the lamp is large in size and is adjusted by four hydraulic cylinders and a number of piston rods. This type of lamp has high cost and complex structure and is not suitable for use in conventional exhibition halls. Patent CN111336427A discloses a focal length adjustment device for an optical spotlight, which drives the telescopic cylinder to move by a motor and drives the convex lens to move synchronously. This adjustment mechanism can only be adjusted in one direction and cannot meet the lighting and backlighting technology requirements of complex handicrafts. Utility Model Content

[0029] In the prior art, excessive lighting intensity will cause irreparable damage to calligraphy and paintings, colored paintings, and silk fabrics. At present, track spotlights are often used to set the lighting of collections. Although track spotlights can meet the relevant functional requirements of different exhibits for lighting, due to the structure of track spotlights, when they are set on the ceiling, they are easy to protrude from the ceiling, and the visual experience is suppressed due to the high floor level of private houses. At the same time, the space gives people the impression of a public museum or art gallery, and cannot effectively meet the lighting needs of private collections.

[0030] In order to solve the problem that the downlight in the prior art cannot meet the lighting requirements of different users and different scenes, and the flexibility and stability of the downlight in adjusting the illumination are low, and the illumination cannot be automatically adjusted; this embodiment proposes a downlight capable of automatically adjusting the illumination, including a mechanized dual-axis system component 1, a lens telescopic system component 2, an outer tube 3, a hollow ball cover 4, and a COB light source 5.
