Rear-view mirror with multiple interchangeable signals for vehicles with two, three, four or more wheels
View Patent ↗The invention relates to a rear-view mirror for vehicles, which consists of compatible, combinable and exchangeable modules such as: (A) and (B), or integrated (A+B), functional, signal, lighting and sensor modules; and structural (C), (D) and (E) modules; cover-housing, body-housing and support which may include functional modules. (A), (B) and (A+B) fulfill their function even if the rear-view mirror is folded. They use a multifocal light source of LED's inserted into a flexible and orientable circuit and/or a mixed rigid-flexible circuit combining LED's+bulbs and other lighting elements, with variable optical and reflective means enabling more than one signal from one same transparent surface with direct light output, indirect-reflected light output and/or through intermediate optical light guides depending on the directions required in the front, the side, the back and the lateral ground for different commands, applications and safety signals.
1. Side mirror with a housing including a positioning device for a reflective element and at least one integrated and assembled light signal emitting module for emitting light signals, said light signal emitting module being covered with a lighting display surface ( 1 ) allowing the passage of the light therethrough, said light signals being generated by a light source having a plurality of light points constituted at least in part by LEDS providing light to the front, side and rear with a restriction so that a driver seated in a vehicle does not directly observe said light signals characterised in that said LEDS are high brightness LEDS inserted in an at least in part flexible printed circuit ( 20 ) capable to suitably adapt to curved shapes with a variable cross-section so that at least two of said light points have different angles of inclination with a suitable orientation providing either a direct light through said display surface or against a reflective part or indirectly through an intermediate optic so that the light is emitted to the front, side and rear, according to functional requirements, determining two differentiated functional areas: a forward projection area (F 1 ) or front spot, that complements the vehicle's front signals, and, a combined focus area (F 2 ) to the side and rear that complements the side and rear signals and;
wherein said flexible printed circuit ( 20 ) is provided with calculated slits ( 21 ), whereby the circuit can be twisted or stretched, arranged at a split-level, or provided with tabs or folds and adapted to curved or flat shapes, or a combination thereof, so that said flexible printed circuit remains fixed between teeth, guides and positioning elements of a support base ( 24 ), a reflective surface ( 12 ) and display surface ( 1 ).
2. Side mirror according to claim 1 , characterised in that the insertion track of positive pole ( 29 ), or cathode, of each LED inserted in a flexible part of said at least in part flexible printed circuit has a greater area than that of the negative pole ( 23 ) defining a heat dissipating surface optimising the thermal and lighting operation and duration of the LED.
3. Side mirror according to claim 1 , characterised in that said light points are made of 20 mA to 350 mA LED chips ( 30 ).
4. Side mirror according to claim 3 , characterised in that said LED chips are of various shape, optic, wavelength, ranging from 350 nm to 1150 nm, or encapsulation and are prepared to emit signals from any source, providing a multifocal signal comprising three focal points with various shapes and colours of the light output.
5. Side mirror according to claim 1 , characterised in that said flexible printed circuit ( 20 ) is made from a flexible material, less than 2 mm thick, selected from the group consisting of fibre glass, treated polyester, soft metal or other materials with similar flexibility which can withstand the welding temperature used to insert said LEDS on the light.
6. Side mirror according to claim 3 , characterised in that said LEDS have different optics and different wavelengths and are used in the same mixed circuit which concentrates the light in a beam or disperses it in the horizontal direction.
7. Side mirror according to claim 1 , characterised in that said light signal emitting module illuminates with an angle greater than 180° measured in the horizontal direction with respect to the driving axis and with an angle greater than 30° measured in the vertical direction.
8. Side mirror according to claim 7 , characterised in that said light signal emitting module covers, wholly or partially, an accurately lit horizontal angle between 0° and 270.
9. Side mirror according to claim 3 , characterised in that said light signal emitting module has at least one light point formed by a LED and another light point formed by an incandescent lamp, said light points being joined electrically in parallel.
10. Side mirror according to claim 3 , characterised in that said light signal emitting module has at least one light point formed by an LED and another light point formed by an electro-luminescent surface.
