Abstract

A rear lamp panel 31 of a road vehicle 1 comprises a plurality of organic light emitting diodes (OLEDs). Areas of the OLED panel can be illuminated to display the lamp functions, in response to the driving behaviour of the driver of the vehicle eg. braking, indicating, reversing. The OLED panel can also be used to display warning messages. The colour and brightness of the OLEDs may be microprocessor controlled. The lamp may be mounted on a glass panel (e.g. window) of the vehicle.

Description

Lamps for a Road Vehicle This invention relates to a lamp for a road
vehicle and particularly to tail lamps of road vehicles.
Road vehicles have a set of tail lamps at the rear of the vehicle to perform various tasks. These tasks commonly include rear position lamps, stop lamps, direction indicators, hazard warning lamps, reversing lamps and fog lamps. Local laws commonly stipulate the number, position, colour, angle of visibility and other characteristics of these lamps, depending on the class of vehicle.
Two types of light source are commonly used for rear lamps of road vehicles.
Primarily, incandescent filament bulbs are used, each bulb performing one or more tasks, a set of bulbs and bulb housings forming a cluster of lamps which performs all the requisite tasks. In addition, a row of red light emitting diodes is used in some road vehicles as a third stop lamp, typically located in the centre of the rear of the vehicle.
The cluster of rear lamps can be visually and physically cumbersome, occupying a significant proportion of the view of the rear of a vehicle and impinging on the space available in the rear storage cavity of a vehicle. The overall appearance of a road vehicle is influenced by the design and layout of the rear lamps. Road vehicle designers face the challenge of incorporating these functional components in an aesthetically pleasing manner.
Each cluster of rear lamps has a number of bulbs and electrical connections.
Rear lamps are often grouped in a single module which is fitted to the rear of the vehicle. These combined modules can be expensive to manufacture and expensive to replace if damaged, for example in a collision.
It is one aim of the present invention to provide an improved tail lamp for a road vehicle which is compact and which can be easily mounted on the exterior of a vehicle.
It is a further object of the present invention to provide a tail lamp which is comprised of a small number of components, requiring low maintenance. It is a further object of the present invention to provide a tail lamp which can provide warning information to drivers or other individuals in the vicinity of the vehicle.
Organic light emitting diodes (OLEDs) are being deployed in user interface displays of electronic devices such as personal computers, hand held computers and mobile telephones, replacing liquid crystal displays (LCDs) which have traditionally been used for these applications. The role of these displays is to display information which can be viewed by a user. In addition to OLEDs being suitable for displaying information, OLEDs are self illuminating and can be used as a multi-coloured light source. LCDs can not be used as a light source in this manner as they are not self illuminating but require an external light source.
Traditional arrays of incandescent filament bulb tail lamps can be replaced with a single OLED panel, either when the vehicle is designed, or the panel can be retro- fitted to an existing vehicle. It is not necessary to dedicate separate areas of the OLED panel for each required function as each area of the panel can display all of the required colours and a microprocessor can control how these colours are displayed, depending on the required tasks as dictated by the actions of the driver of the vehicle.
Traditional light emitting diodes (LEDs) are self illuminating, and consume a relatively small amount of power compared to an incandescent bulb. Typically a 1 2V LED consumes 120mW. Colour LED panels are made of a large number of LED pixels, each pixel being comprised of red, green and blue LEDs. However, to produce an array the size of a vehicle lamp panel, a large number of LEDs are required and the corresponding power consumption is too high to make such an LED panel feasible on a vehicle. Furthermore, OLEDs are easily formed on a curved surface, whereas it is more difficult to form a curved LED panel.
One aspect of the present invention provides a road vehicle comprising one or more lamps, wherein the lamps comprise a plurality of OLEDs.
Preferably a microprocessor is provided to control the electroluminescence of the OLEDs, in particular the colour and brightness of the OLEDs.
Preferably the microprocessor is programmed with a set of pre-programmed lamp configurations to configure areas of the lamps to be one or more of a non- illuminated area, a rear distance lamp, a stop lamp, a reversing lamp, an indicator lamp, a warning lamp or a fog lamp.
Preferably the microprocessor dynamically configures areas of the lamps to be a colour similar to the colour of a body panel of the road vehicle. This will enable the panel to be less conspicuous when no rear lights are required.
Preferably one or more of the lamps is transparent, enabling the lamp to be mounted on the rear window of the vehicle.
Other aspects and preferred features of the invention will be apparent from the accompanying claims. The invention will be further described by way of example with reference to the accompanying drawings in which: Figure 1 is a schematic drawing of a vehicle with a prior art tail lamp array.
Figure 2 is a schematic drawing showing the structure of an OLED.
Figure 3 is a schematic drawing of an embodiment of the invention.
Figure 4 is a cross sectional view taken along line X-X of Figure 3.
Figure 5 is a block diagram showing how the OLED panel is driven.
Figure 1 is a schematic drawing of a vehicle l with two prior art tail lamp arrays 3, one on each lateral side of the vehicle 1. The array 3 is a cluster of lamps comprising a combined rear position lamp/stop lamp 5, direction indicator 7, reversing lamp 9, reflector 11 and fog lamp 13. Each functional lamp has a bulb (not shown) and each bulb has electrical connections. The array 3 fills a noticeable proportion of the rear view of the vehicle 1 and the styling of the array of lamps 3 is critical to produce an aesthetically pleasing overall effect.
The outer panel 15 of the array 3 is formed in one piece and is fitted to the vehicle by screws (hidden from view). If any part of the panel 15 is damaged, the panel is replaced. Each of the bulbs is set back from the outer panel 15 in a reflective recess, thereby reducing the storage space in the rear of the vehicle 1.
Figure 2 is a schematic drawing showing the structure of an OLED 21. An OLED 21 is typically formed from four layers - a transparent substrate 23, a transparent conductive layer 25, an organic layer 27 and a conducting layer 29. The transparent substrate 23 is formed from glass or a suitable transparent polymer. The organic layer 27 is formed from an organic material which emits visible radiation as a result of electro-luminescence when a current is passed through it. The conductive layers 25, 29 are formed of conductive strips which are mutually perpendicular, forming rows and columns, resulting in an OLED pixel at the overlap of each row and column.
When a voltage is applied to a row and a column of the conductive layers 25, 29, the pixel of organic material that is sandwiched therebetween emits light. A voltage of between 2 and 1 0V is required to produce luminescence, this range being conveniently achieved with a vehicle battery which typically produces a voltage in the region of 1 2V.
In this manner, selective areas of an OLED panel can be illuminated as required.
Colour OLED panels can be produced by dividing each pixel into three single colour sub-pixels, each sub-pixel for emitting red, blue and green light. The substrate on which an OLED panel is produced may be curved.
The OLED structure described above is representative of the structure of a passive' OLED. An 'active' OLED could be used, where instead of having perpendicular rows and columns to stimulate electro-luminescence in each pixel, each pixel is stimulated by a transistor which is embedded in an integrated electronic thin film transistor (TFT) backplane which replaces one electrode layer, the other electrode layer being earthed.
Figure 3 is a schematic drawing of an embodiment of the invention. The array of lamps 3 of figure I is replaced with a single OLED panel 31 and a reflector panel 11.
The function of the reflector panel 11 can not be replicated by an OLED and a separate reflector panel 11 is required at the rear of the vehicle 1. It may be preferable not to locate the fog light within the OLED panel 31 to prevent burn out of the panel 31 when the fog lamp is operated. The combined OLED panel 31 and reflector panel 11 are the same shape as the panel 15 of the array of lamps 3 of Figure 1, but the combined panels 31, 1 1 are much thinner than the array of lamps 3. The size of each pixel can be relatively large compared to the size of pixel typically required for a display device such as a computer monitor or hand held computer, as display of fine detail is not required.
A microprocessor dynamically allocates the colour of each pixel, depending on the required function as dictated by the actions of the driver of the vehicle. For example, when travelling at night the whole panel could illuminate red to indicate the rear position lamp. When the driver operates the stop and/or indicator lamp at night, part of the display could be illuminated bright red and/or flashing amber respectively and the remainder could stay red as before. When the tail lamps are not required, for example when the vehicle is parked or when travelling without braking or indicating during the day, the OLED panel 31 can be coloured to match another area of the bodywork.
In Figure 3, an OLED panel 33 is fitted as a third stop lamp to the centre of the top of the rear window 35 of the vehicle 1. The layers of the OLED panel can each be made from transparent material, so that when the OLED panel 33 is turned off it will be transparent and not unduly obscure the view through the rear window 35 of the vehicle.
Similarly, the OLED panel 31 which performs the function of stop lamp, indicator, fog lamp, etc. could also be mounted on the rear window 35 of the vehicle 1.
As well as acting as a light source, the OLED panel 31 can also be used to display information. For example, when the vehicle is parked and alarmed, the OLED panel 31 could display a message such as "Warning! This vehicle is alarmed" or simply "Alarmed!". If a rear proximity sensor is fitted to the vehicle, a suitable warning message could be displayed for the attention of the driver of an approaching vehicle, which could increase in size as the approaching vehicle which draws closer.
The information display function can be combined with the traditional lamp functions to enhance the effectiveness of the latter. For example, when an indicator lamp is required, moving arrows could be displayed within the orange colour portion of the OLED display to show the intended direction of movement of the vehicle. If the vehicle is reversing the word "reversing" could be displayed flashing on a white background. These animated function displays are more eye-catching than static function lamps and would reduce the size of the display required to be visible by other drivers.
Figure 4 is a horizontal cross sectional view 37 taken along line X-X of Figure 3. The OLED panel 31 is mounted on the exterior of the vehicle panel 39, following the contours of the panel 39. A reflector panel 11 is fitted adjacent the OLED panel 31.
The OLED panel 31 can be formed on a curved surface and is only a few millimetres thick, which maximises the storage space available in the rear of the vehicle. The OLED panel 31 can also be retrofitted to an existing vehicle by placing it over an existing rear light cluster.
Figure 5 is a block diagram 41 showing how the OLED panel 49 is driven.
There are various input devices 43 which feed into a microprocessor based controller 45. The input devices 43 are activated by the driver of the vehicle during the course of driving, and may include a headlight/rear position lamp switch, direction indicator switch, brake pedal, gear stick switch (triggered when reversing), hazard warning switch, fog lamp switch, alarm- door locking system and rear proximity sensor. When these input devices are triggered they may illuminate one or more of the rear lamps (a rear proximity sensor may be used to trigger a warning message when an approaching vehicle draws close, as mentioned above). The controller 45 processes the signals from the input devices 43 and determines a suitable configuration for the OLED panel 49.
The controller 45 sends a signal to the OLED driver 47 to configure the OLED panel 49.
Various modifications will be apparent to those in the art and it is desired to include all such modifications as fall within the scope of the accompanying claims.
