Abstract
ABSTRACT OF THE DISCLOSURE
An internal rear-view mirror for a motor vehicle is provided with an oppositely disposed pair of repeater lamps arranged to be connected into the electrical circuit of the vehicle's flashing direction indicators, the output of the lamps being controlled by a light-sensitive device positioned in the rear of the mirror to see substantially the light level incident on the drivers's eyes.

Description
~ID63~
The invention relates to a rear-view mirror arrangement incorporating repeater lamps for connection in a vehicle electrical direction indicating system.
Official statistics show conclusively that a large S percentage of automo~ile accidents occur when drivers turn across the stream of on-coming traffic (a left-hand turn in North America and a right-hand turn in the U.K.) or carry out some form of manoeuvre such as changing lane There can be little doubt that a major factor not only , in these sta~istics but also in man~ other accidents is the insufficient use by the driver of the vehicle's rear ,: view mirror either alone or combined with an insuf~icient .
use of the vehicle's direction indicators. It is thus a common experien~e to follow a dri,ver whose right or left .
hand directional signal flasher xemains in operation for mile after mile.

Exist.ing audible and visual flash~r indicator units are frequently inadequate in congested traffic conditions especially in a vehicle fitted with radio or stereo equipment, or when a driver is negotiating a critical road maneouvre or travelling at high speed. During all these conditions a high degree o~ concentration is xequired of the driver and it is thus often imprudent to look at the dash panel to check whekher or not a directional signal is operating. It is of course for similar reasons that it is now proposed to fit modern fighter aircraft with "head up" instrumant displays.

i~vention, in contraqt, the indicator re~eater lamps in the - mixxor are controlled as regards brillianae by a sensor ~-arranged to see substant.ially the light directed towards the driver's eyes.

6~695 brighten up in response to oncoming light, for ~xample from the headlamps of oncoming vehicles, but not in response to light direct~d towards the sides or rear of the vehicle.
It is also known from U. S. Patent ~o. 3 680 951 to use light sensitive devices to dip a vehicle rear view mirror automa-tically when the lights of a following vehicle are incident thereonO Two ligh~ sensitive devices are used, one facing to the rear o~ the vehicle and the other to one side to~measure the ambient light level. The device operates ; 10 ~ as an on-off switch. It is in no way concerned with indicat-ing lamps or the brilliance thereof, and provides solely a mirror for rear viewing without any other function.
Various proposals have been made to combine direction ` indicators with external rear view mirrors; see for -~ 15 example U.S. Patent ~o. 2 580 014 and British Patent ~o. 258 975. In these proposals the object has been to ` combine external direction indicators ~or warning other . ~ .
road users of intended manoeuvres with an external rear ., i view mirror. They do not provide additional, repeater lamps ~ . .. .
within the driver's peripheral vision when looking forward, and have no provision for dealing with the variations in the light incident on the driver's eyes.
An object of this invention is accordingly to provide , a driver's interior rear view mirror for a vehicle incorporating direction indicator repeater lamps and having means for preventing said repeater lamps from dazzlin~
the driver in low levels o~ general light.

Another object is to render the brilliance of the repeater lamps dependent substantially on the light level incident on the driver's eyes from the extexior of the vehicle.
A rear view mirror arrangement in accordance with the invention for use in a motor vehicle having an electrical circuit for flashing indicators comprises a frame, a reflective panel mounted in the frame, and a pair o~
repeater lamps mounted behind the reflective panel. Means are provided defining windows in the re?flective? panel at opposite ends thereof throuyh which the repeater lamps may shine. Electxic circuit means connected to the repeater lamps to energise the latter are arranged for connection to said flashing indicator electrical circuit. A light lS sensitive device is mounted behind said reflective panel ~; by means which pass a portion of the lighk striking the rear of the mirxor arrangement within an angle of incidence centred on an axis substantially normal to the piane of th~
re1ective panel. The light sensitive device is connected .. . .
in said electric circuit means such that the level o . , .
~ energisation of the repeater lamps varies with the level s of light striking said light sensitive device.

In accordance with the invention, the mirror glass 12 has arrow-shaped windows adjacent both ends, one of which may be seen in Figure 1. The windows 24 are suitably formed by placing a mask on the reverse of the mirror glass to expose the desire~ arrow shape and locally removing the safety covering and silverin~ by sand blasting. It is preferred that the windows 24 are small in xelation to the mirror glass 12 and are provided internally with a coloured transparent layer, suitably red in colour~ --A miniature repeater lamp 26 (only one of which ca~
be seen in Figure 1) is mounted behind each window 24, suitably by glueing the lamp directly to the rear of the mirror glass 12 with a transparent epoxy resin, The ; repeater lamps 26 are connected to an electronic circuit on a printed circuit board 28 mounted on the back plate 14 `s and via wires 29 to the electrical circuit of the vehicle, ... . . .

6;~6~5 vehicle direction indica-tor lamps 36, 38 respectively to the switch 34, and each repeater lamp is connected via a respective diode Dl, D2 to the emitter of a transistor TRl whose collector is connected to vehicle earth (ground).
The base o~ the transistor TRl is biased by -the voltage at the junction of a fixed resistor Rl and the parallel combination of a variable resistor VR and a light-dependent resistor I,DR forming a potential divider across TR1.
ThuS, when the driver operates the right hand direction indicator, the lamp 27 in the mirror flashes in .
synchronism with the vehicle lamp 36, and is visible to the driver as a red light through the appropriate window 24, and vice versa for a lef-t turn indication.
The bias on TRl is varied by the light dependent resistor LDR in accordance with the light incident thereon, .
whereby the repeater lamps 26, 27 are dimmed when the incident light level is low. VRl may be manually adjusted;to set the minimum brilliance~

Returning to Figures 2 and 3, it will be seen that, in acccrdance with the invention, the light-dependent resistor LDR is mounted on the printed circuit board facing the rear o~ the mirror assembly, i.e. to face the front of the vehicle in use. An aperture 40 is formed in the back plate 14 at a location in ~ront of the LDR to permit incident light to pass thereto. Owing to the restricted diameter of the aperture ~0, the thickness of the back plate 14, and the spacing between the back plate 14 and the LDR, the latter receives incident light only within a given cone of incidence around an axis substantially normal to the plane of the mirror glass 12. ~hus the light incident on the LDR is essentially the same as that incident on the driver's eyes and the intensity of the lamps 26, 27 will compensate for such e~ects as oncoming headlights during the hours of darkness.
A second aperture 42 formed .in the back plate 14 allows the insertion of a screwdriver to set the variabla resistance VR.
