Definitions
- the invention relates to a light assembly for illuminating surfaces and/or light media according to the type defined in more detail in the preamble of claim 1.
- the surface can be, for example, a window pane or another glass or plexiglass pane.
- the illustration can be any type of light signal and/or warning sign generated by light beams.
- the light signal or warning can be projected, for example, on a window pane of a motor vehicle.
- US 2018 008 6028 A shows a light source that is coupled to the glazing of a vehicle.
- the light source is a diode and is located on the side next to the glazing.
- a diffuser or a reflector is arranged on a surface of the glazing and spaced from the light source. The light from the light source is introduced into the glazing via an edge surface and extracted or discharged from the glazing via the diffuser.
- the object of the present invention is to create an improved lighting assembly for illuminating surfaces and/or light media, which overcomes the aforementioned disadvantages.
- a light source, a circuit board and at least one lens are arranged in a housing, with at least one holding element being provided which enables the housing to be fastened to a glass carrier in a precise position.
- space-related restrictions can be avoided because all elements are arranged compactly in one housing. For example, an increase in lighting efficiency can be achieved through optimized position tolerance and through optimized reflector properties, since only a compact element, i.e. H. the housing to which glass support must be attached.
- the at least one holding element serves in particular as a mold receptacle for the housing, with the targeted application of force of the at least one holding element on the housing making it possible to fix the housing, in particular by clamping.
- Industrial alignment and tolerance compensation of the components can also be carried out using targeted force.
- the light assembly for illuminating surfaces and/or light media comprises at least one light source, a circuit board, at least one lens and at least one reflector element. All of these elements, except for the reflector element, are arranged completely in the housing.
- the at least one lens serves for optical light distribution and can be designed as a microlens.
- the reflector element contacts this Light guide element and is therefore also directly connected to the housing of the light assembly. This makes subsequent replacement easy and flexible without damaging the optically relevant surfaces of the glass carrier.
- there is no need to pre-assemble the glass carrier for example by cleaning or treating the surface, since the housing can be easily removed from the at least one holding element without additional components and attachments and can therefore be easily replaced.
- a light-guiding element can preferably be arranged in the housing.
- the light-guiding element contacts in particular the circuit board and is in particular completely surrounded by the housing on at least one side and delimited on at least one other side by the reflector element and the glass carrier. This makes it possible in particular to prevent light rays from escaping, since the housing forms a shielding cover outside the glass carrier.
- the circuit board and/or the housing have a white surface. This allows the reflection properties to be increased or improved. This leads to an increase in the efficiency of the entire system. In contrast to a white surface, it may also be sufficient to make the surfaces of the circuit board and/or the housing relatively light.
- the at least one holding element is glued and/or clamped to the housing.
- the housing with the holding element is fixed to the glass carrier, in which the holding element is firmly connected to the glass carrier and the housing is held in a clamping manner on the holding elements. This makes it easy to replace the Housing, and thus the complete lighting assembly, can be carried out. This enables a cost-effective service option.
- Fig. 1 shows a possible embodiment of the light assembly
- the housing 5 is held via two holding elements 6, the holding elements 6 being designed in the shape of a hook.
- each of the holding elements 6 is L-shaped, with the holding elements 6 being arranged mirrored to one another.
- a restoring force is illustrated by an arrowhead shown at a free end of each holding element, the housing 5 being held in a clamping manner by the two holding elements 6.
- the described embodiment variants of the light assembly 1 in Figures 1 to 3 can also be combined with one another, so that various possibilities arise.
- the embodiment according to FIG. 3 can be designed without a glass carrier 7′.
- the arrangement and number of lenses 3 can vary.
