Technical Field

The invention relates to the technical field of spot lamps, in particular to an intelligent high-power chip-level entertainment lighting source module.

Background

The spotlight is a common lighting tool, has wide application, can be used as stage lighting to increase the stage effect and improve the light sensation of stage performance; the LED lamp can also be used as searchlighting, so that illumination can be conveniently carried out in a dark environment; the LED lamp can also be used as illumination for medical operations, provide sufficient light for doctors to perform operations, and the like.

Spotlights, when used for entertainment, are most often used to focus and vary the aperture range. This is often done by changing the distance of a planar convex lens in front of the light source relative to the light source. This usually requires a sufficient spacing to ensure that the focusing effect is achieved to a certain extent, which necessarily increases the spatial dimensions of the spotlight, which in turn increases the material usage and hence the cost. In order to further meet the requirement of changing the aperture range, some spotlights are implemented in a small-sized space, and part of light of a light source is directly sacrificed, so that the brightness of the aperture is affected, and the illumination quality is reduced.

Therefore, it is an urgent problem to design a spotlight that can change the aperture range without losing the light of the light source in a small space size.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Example 1:

please refer to fig. 1, which shows a schematic structural diagram of an intelligent high-power chip-level entertainment lighting source module. The embodiment of the invention provides an intelligent high-power chip-level entertainment lighting source module.

The intelligent high-power chip-level entertainment lighting source module comprises a lampshade 01, a hydraulic driving mechanism 02, a curved surface extrusion mechanism 03, a guide seat 04, an LED light source 05, a variable curved surface reflector 06, a plane convex lens 07 and a zooming connecting rod mechanism 08. One end of the lampshade 01 is provided with a light hole. The planar convex lens 07 is embedded in the light hole. The curved surface extrusion mechanism 03 is positioned in the lampshade 01 and is coaxially arranged with the plane convex lens 07. The variable curved surface reflecting mirror 06 is clamped on the curved surface extrusion mechanism 03. The hydraulic drive mechanism 02 abuts the curved surface extrusion mechanism 03. The guide seat 04 is disposed along the axis of the planar convex lens 07. One end of the zooming link mechanism 08 is connected with the curved surface extrusion mechanism 03, and the other end of the zooming link mechanism passes through the guide seat 04 and the variable curved surface reflector 06 once and then is connected with the LED light source 05.

Under this intelligence high power chip level amusement illumination light source module, come to actuate curved surface extrusion mechanism 03 through hydraulic drive mechanism 02, make curved surface extrusion mechanism 03 extrusion variable curved surface speculum 06, let variable curved surface speculum 06 take place the change of camber, and then change the light source and send irradiant scope, the change of focusing light ring scope is realized to the irradiation range through changing the light source like this, can be further reduce the distance between plane convex lens 07 and the light source, the light source all can shine away through plane convex lens 07 all the time simultaneously, avoided the irradiant waste of light source.

The details of each substructure are described in detail below:

the convex lens is embedded in the lampshade 01 and used as a focusing lens, and the curved surface characteristic of the convex surface of the convex lens can be determined according to the requirements of field entertainment. The variable curved surface reflector 06 is made of a material with a certain deformation, which may be an alloy with memory characteristics or other deformation materials. It should be noted that the zoom link mechanism 08 is connected to the LED light source 05 after passing through the variable curved surface reflector 06, so that a through hole is formed in the bottom of the variable curved surface reflector 06 along the axis of the convex planar lens 07, on one hand, the through hole is through which the zoom link mechanism 08 passes, and on the other hand, the stress distribution of the variable curved surface reflector 06 in the curvature change process can be changed, because when the curvature change occurs to the variable curved surface reflector 06, the stress at the through hole is most concentrated, and the distribution of the stress can be changed after the through hole is formed, so as to disperse the stress at the through hole, thereby ensuring the service life of the variable curved surface reflector 06.

The LED light source 05 is used as a light source for irradiation, and is required to provide the maximum amount of parallel light beams to the planar convex lens 07 as much as possible so that the planar convex lens 07 completes focusing. Therefore, it is necessary to ensure that the LED light source 05 is located at the focal point of the variable curved reflector 06, so that most of the light beam irradiated to the planar convex lens 07 is shaped into parallel light beams, which is beneficial to focusing and improves the illumination brightness of the focusing aperture.

The curved surface extrusion mechanism 03 mainly realizes extrusion of the variable curved surface reflecting mirror 06 to change the curvature thereof. Therefore, the form and the kind of the curved surface pressing mechanism 03 are various, and in the present embodiment, the curved surface pressing mechanism 03 includes the pressing blocks 31 which are oppositely arranged. A displacement gap 33 is formed between the two pressing blocks 31. The side wall of the pressing block 31 contacting the variable curved surface mirror 06 forms a holding inclined surface 311. The guide block 04 is located in the displacement gap 33.

The variable curved surface reflecting mirror 06 is extruded by the two symmetrical extrusion blocks 31, and the extrusion blocks 31 are symmetrically arranged, so that the variable curved surface reflecting mirror 06 can be uniformly stressed during extrusion, and cannot be damaged due to uneven stress. The arrangement of the abutting inclined surface 311 can ensure that the extrusion block 31 and the variable curved surface reflector 06 are always in point contact, so that the situation that the shaping of the light source in the whole arc-shaped area is influenced due to different curvatures of the whole variable curved surface reflector 06 caused by other types of contact during extrusion can be avoided.

It should be noted that the variable curved surface mirror 06 is in contact with the abutting inclined surface 311 on the pressing block 31, and may possibly slip off. Therefore, in order to prevent the variable curved surface reflector 06 from slipping out of the extrusion block 31, the end of the extrusion block 31 close to the plane convex lens 07 is convexly provided with the baffle ring 32 to block the slipping, so that the use safety is ensured.

The pressing of the variable curved mirror 06 needs the hydraulic drive mechanism 02 to be realized. The hydraulic drive mechanism 02 is various in form and kind, and in the present embodiment, the hydraulic drive mechanism 02 includes a hydraulic pump and a ram. The actuating cylinder is fixed in the lampshade 01. The ram of the ram is connected to the ram 31. The actuator cylinder is communicated with the hydraulic pump.

The hydraulic driving mechanism 02 is selected to realize the extrusion of the variable curved surface reflecting mirror 06, so that the extrusion is stable and uniform in stress of the variable curved surface reflecting mirror 06, and the service life of the variable curved surface reflecting mirror 06 cannot be influenced by unstable impact caused by using other mechanical driving modes.

In addition, it should be noted that, since the LED light source 05 needs to be always at the focus of the variable curved reflector 06, the curvature change motion of the variable curved reflector 06 and the motion of the LED light source 05 are not independent, and the two motions change regularly. Since the change in curvature of the variable curved mirror 06 is achieved by the movement of the curved pressing mechanism 03, in the present embodiment, the zoom link mechanism 08 is provided to link the movements of the two.

In the present embodiment, the zoom link mechanism 08 includes a turning link and a guide link 83. The rotational link includes a first link 81 and a second link 82 connected together and angularly disposed. The connection part of the first connecting rod 81 and the second connecting rod 82 is hinged with the lampshade 01. The first link 81 is connected to the curved surface pressing mechanism 03. The second link 82 is hinged to the guide link 83. The guide connecting rod 83 passes through the guide seat 04 and the variable curved surface reflector 06 once and then is connected with the LED lamp source.

The angle between the first link 81 and the second link 82 and the length of the guide link 83 are adjusted by design to ensure that the position change of the LED light source 05 is consistent with the curvature change of the variable curved surface reflector 06, so that the LED light source 05 is always positioned at the focal point of the variable curved surface reflector 06.

The guide seat 04 is mainly arranged to ensure that the movement of the LED light source 05 is always located on the axis of the planar convex lens 07. It should be noted that the variable curved surface mirror 06 is deformed by being pressed, and the elastic force generated by the deformation causes the variable curved surface mirror to move in a direction approaching the planar convex lens 07 along the abutting inclined surface 311, and therefore, in order to stabilize the position of the variable curved surface mirror 06, the sliding ring 41 is fitted over the guide holder 04. The sliding ring 41 is connected with the variable curved surface reflector 06 through a limiting connector 09. The limiting connection body 09 has elasticity, and the elastic force of the limiting connection body 09 is smaller than the friction force between the sliding ring 41 and the guide seat 04.

The reason why the elastic force of the limiting connecting body 09 is smaller than the friction force between the sliding ring 41 and the guide seat 04 is to ensure that the pulling force of the variable curved surface reflecting mirror 06 on the limiting connecting body 09 does not pull the sliding hole to slide, so that the position of the variable curved surface reflecting mirror 06 is not changed.

Of course, in order to ensure that the variable curvature mirror 06 moves within the allowable range of curvature variation, thereby achieving a prescribed range of aperture focusing, the stretchable length of the limit connector 09 needs to be greater than the range of movement of the variable curvature mirror 06 along the axis of the slide ring 41. In addition, a limit ring 42 is convexly arranged on one end of the guide seat 04 close to the variable curved surface reflector 06 around the axis thereof, so that the sliding ring 41 can be prevented from suddenly slipping.

In this embodiment, spacing connector 09 is the rubber rope, and the elastic force that the rubber body had can not be too big on the one hand, can guarantee to realize dragging the stability of variable curved surface speculum 06, and on the other hand adopts the mode of the rope body also to conveniently set up and the stress point of homogenization.

The embodiment of the intelligent high-power chip-level entertainment lighting source module provided by the embodiment is as follows:

when the light condensation range needs to be changed, the piston rod pushes the curved surface extrusion mechanism 03 by actuating the hydraulic driving mechanism 02, so that the curved surface extrusion mechanism 03 extrudes the variable curved surface reflector 06 to change the curvature of the variable curved surface reflector, meanwhile, the position of the LED light source 05 is also driven by the zoom connecting rod mechanism 08 to move, when the curvature is stable, the range of parallel light beams formed by the LED light source 05 is changed, and the range of the light beams focused by the plane convex lens 07 is changed.

The described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
