Problems solved by technology

[0003] However, as people's requirements for lighting effects continue to increase, the demand for humanization of lamps continues to increase, especially in high-altitude applications. It is very difficult to debug application scenarios such as illumination direction, angle, brightness, and color temperature when using lamps; thus It will inevitably lead to an increase in the debugging and maintenance workload of LED spotlights when they are applied in the high-altitude field, and the maintenance cost will also gradually rise.

Embodiment 1

[0025] The invention provides a downlight that can realize multi-direction adjustment such as vertical expansion and contraction, horizontal rotation, and irradiation angle deflection.

[0026] The downlight specifically includes adjustment mechanisms in three directions, and also includes a control module for controlling these adjustment mechanisms.

[0027] In terms of overall structure, such as figure 1 As shown, it includes a housing, an adjustment bracket arranged in the housing and parallel to the axial direction of the lamp body, an adjustment platform installed on the adjustment bracket, and a light source unit installed on the adjustment platform. The adjustment bracket is used for fixing the light source part and cooperating with a plurality of adjustment mechanisms. The adjustment bracket includes a plurality of transmission tooth rods coaxial with the lamp body. In order to ensure that the light source can expand and contract smoothly, the number of transmission t...

Embodiment 2

[0031] As a supplement to Embodiment 1, the difference between this embodiment and Embodiment 1 is that, as figure 2 As shown, the shape of the adjustment platform in this embodiment matches the shape of the downlight, and is approximately circular. A plurality of transmission tooth bars pass through the edge of the adjustment platform, and the lower surface of the adjustment platform is provided with transmission gears and toothed discs. , The transmission structure is formed by the transmission gear between the chainring and the transmission tooth rod. Wherein the transmission gear is sleeved on the transmission tooth rod, and its inner wall is provided with internal teeth matching with the thread of the transmission tooth rod, and the outer wall is provided with external teeth matching with the tooth disc. When the chainring rotates, it drives the transmission gear to rotate. During the rotation of the transmission gear, its internal teeth will cause the horizontal positio...

Embodiment 3

[0036] As a supplement to Embodiments 1 and 2, the difference between this embodiment and Embodiment 1 is that, as image 3 As shown, on the horizontal rotating structure, the top of the light source part is connected with a horizontal rotating structure that passes through the adjustment platform. It is fixedly connected with the gear plate and the adjustment platform to ensure its free rotation without affecting the rotation of the gear plate. The end of the horizontal rotation structure is fixed with a horizontal rotation gear, and the second drive motor fixed above the adjustment platform engages with the horizontal rotation gear and drives it to rotate.

Abstract

The invention relates to a multi-directional adjusting down lamp. The multi-directional adjusting down lamp comprises an adjusting support, an adjusting platform and a light source part, wherein the adjusting support is arranged inside a shell and is parallel to the axial direction of a lamp body; the adjusting platform is arranged on the adjusting support and moves in the axial direction of the adjusting support; and the light source part is connected with the adjusting support, and the deflection angle and the rotating angle of the light source part can be adjusted. The adjusting support comprises a plurality of transmission threaded rods which penetrate through the edge of the adjusting platform, transmission gears and gear plates are arranged on the lower surface of the adjusting platform, internal threads engaged with the transmission threaded rods are arranged on the inner surfaces of the transmission gears, external threads engaged with the gear plates are arranged on the outersurfaces of the transmission gears, and the gear plates are driven to rotate through a first driving motor arranged above the adjusting platform. The multi-directional adjusting down lamp has the following technical effects that (1) multi-directional adjusting is realized through ingenious structure design; (2) through the mode of the transmission threaded rods, telescoping is more stable, and thestructure is firmer; and (3) remote control can be achieved, and thus the adaptability to application scenarios is greatly improved.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a multidirectional adjustment downlight. Background technique [0002] With the continuous progress and development of LED technology, it has been widely used as a light source in people's daily life. At present, LED spotlights have become widely used lighting fixtures in commercial lighting places due to their advantages such as low power consumption, long irradiation distance, and long service life. [0003] However, as people's requirements for lighting effects continue to increase, the demand for humanization of lamps continues to increase, especially in high-altitude applications. It is very difficult to debug application scenarios such as illumination direction, angle, brightness, and color temperature when using lamps; thus It will inevitably lead to an increase in the debugging and maintenance workload of LED spotlights when they are used in high-altitude fields, and the main...
