Description
Technical Field
The utility model relates to a projection lamp module. In addition, the utility model also relates to a projection system comprising the projection lamp module. In addition, the utility model also relates to a vehicle comprising the projection system.
Background
Projection lamp systems typically include a light source, an illumination lens, a film (gobo), and an imaging lens. The system may be applied to symbol projection lamps, such as indoor symbol projection or external light carpet projection. The projection lamp system is particularly applicable to projection systems of vehicles, such as in-vehicle and out-vehicle symbol projection systems and/or exterior light carpet projection systems.
Background artdevices for illuminating the environment outside a vehicle are known from the prior art, for example from document US 9919644B 2, which discloses a motor vehicle comprising an ambient lighting device for generating a light distribution on the ground surrounding the motor vehicle. The ambient lighting device has one or more projection modules for generating a light distribution, wherein a respective projection module comprises an array of optical projection devices and at least one light source. The array of optical projection devices generates at least a portion of the light distribution from the light of the at least one light source. The respective projection module is designed such that each optical projection device projects a single image onto the ground, which single image covers substantially the entire light distribution, and the light distribution is a superposition of the single images of the optical projection devices.
The projection module in document US 9919644B 2 uses a miniature projection module, for example a Micro Lens Array (MLA) projection lamp. The field of view achieved by such miniature projection modules is typically limited, and typically does not exceed 40 °. This means that the projection size of such a projection module is small and more than two such modules need to be used to achieve the desired large projection area. This adds cost and requires additional mode/pattern adjustment within the module, and the projected light distribution may not be uniform after combining the projected areas of multiple projection modules.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to provide a projection luminaire module which can be used alone in a projection system of a vehicle and which enables a sufficiently large projection area, in particular a field angle of more than 110 °, preferably more than 120 ° and less than 150 °, to be achieved.
This object is achieved by a projection luminaire module according to the utility model.

In general, to ensure that the projection lamp module is small in size, the field angle and illumination width are sacrificed, and the field angle of a micro-projection module such as a common micro-lens array (MLA) projection lamp is usually smaller than 40 °. In this case, if a large projection area is to be achieved, a plurality of such miniature projection luminaire modules must be combined. This not only increases cost, but also requires additional mode/pattern adjustments within the module.
