Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a lighting lamp with a variable light output angle. Background Art

[0002] A lamp is a lighting product, generally referring to an appliance that can illuminate. In ancient times, humans used torches for lighting, and later candles and oil lamps appeared. In modern times, electric lamps appeared. There are many types of lamps, which can be divided into fixed and adjustable types according to their structure. Adjustable lamps usually have adjustable light output angles.

[0003] In the related art, the area that can be illuminated by an adjustable lamp is usually small, and the illuminated area needs to be changed by changing the angle of the light source, which cannot achieve cross-lighting in a large area and the lighting effect is monotonous. Therefore, it is urgent to improve. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a lighting fixture with variable light output angle, which can realize cross-light output in a large area and enrich the lighting effect.

[0005] According to an embodiment of the first aspect of the present invention, a lighting fixture with a variable light output angle comprises a lamp holder, wherein the middle portion of the lamp holder bulges inwardly and forms a power supply slot on the outer side, a driving power supply is installed in the power supply slot, and two lamp slots are symmetrically arranged on the inner side of the lamp holder on both sides of the power supply slot; both ends of the lamp holder are detachably connected with end plates, a rotating shaft is rotatably connected between the two end plates at each lamp slot, a lamp body is fixedly connected to the rotating shaft, a cable is provided between the lamp body and the driving power supply, and the lamp body is provided with a silicone pad abutting the end plate; a transmission box is provided on the outer side of the end plate, and a linkage component for causing the two rotating shafts to rotate synchronously and a separation component for causing the linkage component to separate to allow the two rotating shafts to rotate independently are provided in the transmission box.

[0007] The lamp holder is used to connect with a wall or a hanging piece to fix the lighting fixture with a variable light output angle of the present invention, and is used to provide support for other components. The middle part of the lamp holder bulges inward and forms a power slot on the outside, which has a simple structure, high strength and long service life, and is conducive to heat dissipation of the driving power supply.

[0008] Two lamp slots are symmetrically arranged on both sides of the power slot on the inner side of the lamp holder, providing a large area lighting function after the lamp body is installed; both ends of the lamp holder are detachably connected with end plates to support the shaft and the lamp body, and to form a covering and blocking effect to prevent the lamp body from falling off;

[0009] The lamp body can rotate relative to the end plate and the lamp trough through the rotating shaft, so that the angle of the lamp body can be adjusted to change the irradiation range. Since two lamp bodies are provided, a large area of ​​cross-lighting can be achieved to enrich the lighting effect. The lamp body is provided with a silicone pad that abuts against the end plate. When the lamp body is rotated, friction is generated between the silicone pad and the end plate, which is used to fix the lamp body at any angle. When the lamp body is rotated to the desired angle, it can be quickly fixed to prevent the lamp body from rotating freely.

[0010] A linkage component is provided in the transmission box, which can cause the two shafts to rotate synchronously to form a cross-lighting effect, and the lighting area will not be significantly reduced; and the separation component causes the linkage component to separate to make the two shafts rotate independently, which can make the lighting area and effect more flexible and rich.

[0011] According to some embodiments of the present invention, a plurality of mounting holes are provided on the edge of the lamp holder.

[0012] According to these embodiments of the present invention, at least the following beneficial effects are achieved: the mounting holes are convenient for connection with walls and hanging parts, etc., which is conducive to firmly fixing the lighting fixture with a variable light output angle of the present invention, and is convenient for repair and maintenance.

[0018] According to these embodiments of the present invention, at least the following beneficial effects are achieved: when the lamp body rotates to the extreme angle, the silicone pad abuts against the limit bar, and the lamp body cannot continue to rotate, thereby limiting the lamp body and preventing the lamp body from over-rotating and getting stuck or falling off.

[0019] According to some embodiments of the present invention, the linkage assembly includes a first pulley coaxially connected to one of the rotating shafts, a spline shaft is provided in the transmission box, the spline shaft is parallel to the axis of the first pulley, the spline shaft is provided with a second pulley, the second pulley is connected to the first pulley for transmission via a first belt, the spline shaft is longitudinally slidingly connected to a first gear, a second gear meshingly connected to the first gear is rotatably connected in the transmission box, the second gear is coaxially connected to a third pulley, the other rotating shaft is coaxially connected to a fourth pulley, the fourth pulley is connected to the third pulley for transmission via a second belt; the separation assembly causes the first gear to slide longitudinally along the spline shaft and separate from the second gear.

This arrangement can realize the synchronous and counter-rotating rotation of the two lamp bodies, thereby realizing cross-lighting in a large area and enriching the lighting effect. Only one of the rotating shafts needs to be rotated to drive the two lamp bodies to rotate synchronously in counter-rotating directions at the same time, which is convenient and quick to use.

[0021] When the separation component works, it causes the first gear to slide longitudinally along the spline shaft and separate from the second gear, cutting off the power transmission between the two shafts. The two shafts can rotate independently, making the lighting area and effect more flexible and rich.

[0022] According to some embodiments of the present invention, the separation assembly includes a fixed shaft arranged in a transmission box, the fixed shaft is parallel to the axis of the spline shaft, the fixed shaft is connected to a separation fork along its axial sliding direction, the first gear is coaxially connected to a separation ring, and the separation fork is correspondingly clamped with the separation ring.
