Definitions

• This invention concerns a vehicle light unit according to the preamble of claim 1. It also concerns a modification thereof.
• DE-A1-19 53 0617 relates to locating equipment such as an antenna on the front wind screen of a car and DE-U1-29 60 6475 concerns flat antennas for application to a non metallic material detail of the vehicle body such as the front or the rear wind screen.
• DE-A1-196 16 974 concerns a rear light unit being applied at the upper side of the glass panel .
• the unit is mounted into a hole in the rear view window in order to avoid losses in light transmission through the glass panel .
• This unit may also include an antenna.
• the antenna per se does not provide extra limitation to the view through said glass panel since this portion used is already occupied by the light function.
• the mounting of this unit is however expensive and complicated, since the hole in the window has to be cut by i . a . a laser cutter, a water- jet cutter or the like.
• the light means comprises vehicle brake light means, because brake light units are possible to place such in the vehicle that the brake light function as well as the antenna function is easy to optimise.
• the feature according to claim 5 makes it possible to further minimise possible influence of radiation on passengers.
• claim 6 accentuates the ease of mounting.
• Claim 7 concerns economic production of the antenna.
• Fig. 1 shows a brake light unit according to the invention in a longitudinal section
• Fig. 2 shows diagrammatically a brake light unit mounted at the upper portion of a rear window of a motor vehicle
• the light unit 1 in Fig. 1 is a brake light unit comprising a housing 2, for example of a synthetic material having radiation suppressing properties.
• the housing as usual, encloses a brake light assembly 3 including one or several brake lamps 4 and a reflector 5.
• the brake light unit according to Fig. 1 is intended to be mounted at the upper part of the inclined rear window glass panel of a car, whereby the housing portion 6 in use is horizontal and adapted for containing, in a space so as not to obstruct visibility of the brake light, an antenna element 8 provided on a carrier 7.
• the upper rear edge 9 of the brake light unit housing 2 is intended to be placed tightly against said glass panel.
• the upper front edge 10 of the brake light unit housing is intended to be placed against an inside part of the roof of the vehicle.
• the brake light unit 1 is as is common technology fixed against the rear roof portion by fasteners such as screws or the like.
• 13 depicts an antenna cable to be contacted to the antenna element 8 over a contact means 16.
• 15 depicts electric lead to the brake lamp 4.
• These leads 13, 15 are united in a common cabling 14, which simplifies installation. Also separate cables comprising the cabling is within the scope of the invention.
• the location of the brake light unit 1 inside the car will be more apparent from Fig. 2. Radiation emanating from and/or reaching the separate elements of the antenna unit will pass through the adjacent portion of the glass panel.
• Fig. 3 shows the light unit in a perspective view, wherein antenna element 8 is shown as an antenna for radio communication purposes.
• the antenna carrier 7 may be provided with a signal amplifier (not shown) for the antenna and/or a compensation circuit (not shown) for compensating loss in antenna cable.
• the antenna carrier may carry different antennas such as for mobile phones, GPS, digital radio etc.
• the invention may be modified within the scope of the following claims.
• the portion of the housing adapted for reception of the antenna unit may in certain applications be provided elsewhere than at the lower portion of the housing, e. g. at an upper portion.
• the housing differently from what is shown in Fig. 1. It is thus possible to provide a protection surface or the like, e.g. including conductive means, in the housing material or between the housing and the antenna so as to prevent radiation from entering the passenger compartment of the vehicle or at least to suppress such radiation.
• a protection surface or the like e.g. including conductive means
• the light means is excluded and another electric or electronic piece of equipment is included.
