The embodiment of the invention provides a rotating type light beam pattern adjusting device and lighting and / or signal indicating equipment. The rotating type light beam pattern adjusting device comprises a light incident surface, a first light deflection surface, a first light exit surface, a second light deflection surface and a second light exit surface, wherein the first light deflection surface can enable light beams which are incident from the light incident surface to deflect towards the first light exit surface when the rotating type light beam pattern adjusting device is at the first rotating position, the first light deflection surface can enable the light beams which are incident from the light incident surface not to deflect when the rotating type light beam pattern adjusting device is at the second rotating position, the second light deflection surface is arranged to enable the light beams which are incident from the light incident surface to deflect towards the second light exit surface when the rotating type light beam pattern adjusting device is at the second rotating position, and the second light deflection surface can enable the light beams which are incident from the light incident surface not to deflect when the rotating type light beam pattern adjusting device is at the first rotating position, and first patterns are formed in at least one of the first light deflection surface and the first light exit surface and used for conducting patterning on the light beams.
Description
technical field [0001] The present invention relates to the field of illumination and signal indication, in particular to a rotary beam pattern adjustment device and illumination and / or signal indication equipment comprising the rotary beam pattern adjustment device. Background technique [0002] Lighting devices and signal indicating devices are widely used in various aspects of people's production and life, such as lights of motor vehicles, street lights, advertising lights and so on. With the development of people's individual needs, there are more and more requirements for the visual effects of lighting devices and signal indicating devices. It is often expected that the light beams emitted by the lighting device and the signal indicating device can have more various lighting effects, for example, can present certain patterns. And this patterning requirement will often lead to the complexity and bulkiness of the system. Therefore, there is an urgent need for a light be...
