Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0046] Such as figure 1 Shown is the first embodiment of the spotlight 10 of the present invention that can change the projection area arbitrarily. The spotlight includes a light source module 11 that provides projected light, a scanning mirror module 12 that converts and projects the light from the light source module 11, and obtains tracking The tracking signal acquisition module 13 of the signal, and the control unit 14 connected with the tracking signal acquisition module 13 and the scanning mirror module 12; the control unit 14 controls the scanning mirror module 12 to adjust the projection area according to the tracking signal.

[0047] The light source module 11 can adopt a light source with strong light-gathering ability, such as a laser light source, LED, etc., to provide directional projected light.

[0048] The scanning mirror...

Abstract

The invention provides a reflector lamp capable of randomly changing projection areas, a following projection system and an implementation method of the following projection system. The reflector lamp can be used for illuminating a tracked object and comprises a light source module providing projection light, a scanning mirror module converting and projecting light rays of the light source module, a tracking signal obtaining module for obtaining tracking signals and a control unit connected with the tracking signal obtaining module and the scanning mirror module. The control unit controls the scanning mirror module to move to adjust the projection areas according to the tracking signals. On the basis of the reflector lamp, the invention further provides the following projection system composed of a remote controller and the reflector lamp, wherein the remote controller is matched with the reflector lamp in use, and accordingly control and use of the reflector lamp are facilitated. The reflector lamp, the following projection system and the implementation method have the advantages of being easy to install and use, capable of automatically following an object in real time and various in projection light type.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a spotlight capable of arbitrarily changing the projection area, a follow-up projection system using the spotlight and a method for realizing the follow-up projection system. Background technique [0002] At present, spotlights are used in many occasions. For example, on some vehicles (such as airplanes, trains, high-speed trains, and long-distance buses), small spotlights are usually installed above the passenger seats, so that passengers can illuminate when the light is dark. However, when this spotlight is turned on, the lighting area is basically limited. Due to the scattering of light, it will affect the people resting next to it, which is not conducive to use. [0003] In addition, spotlights can also be applied to the stage. Traditional stage spotlights can be manually controlled to adjust the projection direction, area, etc. of the spotlights; however, this requires skilled oper...
