Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to a lamp. Background Art

[0002] LED floodlights are widely used in different scenarios, such as displaying exhibits, lighting corridors, decorating building exteriors, illuminating billboards and sculptures, etc., to highlight the unique charm of buildings and enhance visual effects. At the same time, they are also widely used in landscape lighting in open spaces such as parks, squares and playgrounds, adding a sense of security and aesthetic value to the environment.

[0003] With the continuous advancement of LED technology and the maturity of production processes, modern LED floodlights have achieved significant improvements in light efficiency and durability. However, most LED floodlights on the market still face a technical limitation: they can only emit beams at fixed angles and cannot adjust their beam angles according to specific needs. This limitation may limit certain specific usage scenarios, such as when it is necessary to control the light coverage or directionality of the beam, or some usage scenarios may require the light to be accurately focused in a small area, while other cases require the light to be widely distributed over a large area.

[0004] Therefore, Xidai developed an LED floodlight with adjustable light-emitting angle so that users can flexibly adjust it according to specific application requirements, thereby better meeting customers' lighting needs in different usage scenarios. Utility Model Content

[0061] The implementation principle of a lamp in the embodiment of the present application is as follows: the present application mainly realizes the adjustment of the light-emitting angle of the lamp by designing a lifting mechanism 4, and by designing a power and color temperature controller 7 and a light control belt code switch assembly 8, so that the lamp of the present application can be provided with the functions of color temperature and power adjustment and whether to turn on or off the light control function, effectively improving the functionality and practicality of the lamp, and providing users with more flexible and diversified lighting solutions;

[0062] When it is necessary to adjust the light-emitting angle of the lamp, the user can use a tool to rotate the rotating head 6, and the rotating head 6 drives the crank 45 connected thereto to rotate, and the crank 45 drives the transmission shaft 42 to rotate, and the transmission shaft 42 drives another crank 45 to rotate. During the rotation of the crank 45, the crank 45 drives its convex rod 46 to rotate, and the convex rod 46 rotates in the first cam groove 441 and the second cam groove 431. At this time, through the design that the first cam groove 441 and the second cam groove 431 are staggered and partially overlapped, this mechanism can provide accurate position adjustment, so that the first cam groove 441 and the second cam groove 431 are staggered and partially overlapped. The groove 441 moves up and down relatively along a direction perpendicular to the axial direction of the transmission shaft 42, so that the movable plate 44 moves up and down along the direction perpendicular to the axial direction of the transmission shaft 42. During this process, the movable plate 44 can move up and down in a vertical direction along the sliding limit groove 47. The sliding limit groove 47 limits the moving range of the movable plate 44, ensuring that the movable plate 44 moves within the designed effective working range, so that the movable plate 44 can stably drive the lens assembly 3 to move up and down, thereby adjusting the distance between the lamp panel assembly 2 and the lens assembly 3, thereby changing the light-emitting angle of the lamp;

[0063] During this process, the user can rotate the rotating head 6 through the indication mark 61 on the rotating head 6 and the angle mark 51 on the decorative cover 5 to obtain the required luminous angle. When the indication mark 61 is at the 90° position of the angle mark 51, the crank 45 is deflected to the left relative to the vertical direction in the lamp housing body 1. At this time, the lens assembly 3 and the lamp board assembly 2 are arranged in a close fit, and the luminous angle of the lamp board assembly 2 is 90°; when the indication mark 61 is at the 75° position of the angle mark 51, the crank 45 is in the lamp housing body 1 relative to the vertical direction. The movable plate 44 overlaps in the vertical direction. At this time, the movable plate 44 moves upward, driving the lens assembly 3 to move upward, and the lens assembly 3 is separated from the light board assembly 2 by a certain distance. At this time, the luminous angle of the light board assembly 2 is 75°; when the indicator mark 61 is located at the 55° position of the angle mark 51, the crank 45 is biased to the right relative to the vertical direction in the lamp housing body 1. At this time, the movable plate 44 continues to move upward, driving the lens assembly 3 to continue to move upward, and the lens assembly 3 is separated from the light board assembly 2 by the maximum distance. At this time, the luminous angle of the light board assembly 2 is 55°.
