Spotlight with extension-type adjustable light-emitting module

Abstract

The invention discloses a spotlight with an extension-type adjustable light-emitting module, belongs to the technical field of lamp illumination. A lamp tube is rotatably arranged on a mounting seat along an inclined rotating axis, a light-emitting module capable of stretching out and drawing back relative to the lamp tube is spirally mounted on the lamp tube through a first connecting mechanism,the light emitting direction of the light-emitting module is obliquely arranged relative to the rotating axis direction of the lamp tube, so that when the lamp tube rotates relative to the mounting seat, the light emitting direction of the light-emitting module deviates, and meanwhile, under the action of the first connecting mechanism and a limiting rod, the position of light-emitting module stretches out and draws back relative to the lamp tube in the light emitting direction. According to the spotlight, the position of the light-emitting module is subjected to offset adjustment and telescopic adjustment at the same time, so that light rays can be effectively prevented from being intercepted or shielded, integrity of inner facula and the outer facula can be guaranteed, and the light emitting effect is good.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a spotlight with a scalable and adjustable light-emitting module. Background technique [0002] Spotlight is a lamp that people often use. It is mostly used for stage lighting, banquet lighting, and home TV background lighting. It includes a lamp tube and a lamp housing. The two sides of the lamp tube are connected to the lamp body by screw rotation to adjust the light output angle. At this time, turn the lamp tube with the screw as the rotating shaft to adjust the light output angle. Since the light source is always located in the middle of the two screws, when the light is emitted obliquely, the light is easily irradiated at the gap between the end cover and the lamp body, resulting in interception, or due to the occlusion of the lower end surface of the lamp body, the light utilization rate is insufficient, and the light The light spot produced after injection is in...

Problems solved by technology

Since the light source is always located in the middle of the two screws, when the light is emitted obliquely, the light is easily irradiated at the gap between the end cover and the lamp body, resulting in interception, or due to the occlusion of the lower end surface of the lamp body, the light utilization rate is insufficient, and the light The light spot produced after the injection is incomplete, which greatly affects the lighting effect of the spotlight
