The vehicle light 1 has at least one face 6 comprising a double wall 7 which defines a cavity 8. The second chamber 5 is in flow commu­nication with the cavity 8.

Description

A vehicle light and a vehicle including at least one vehicle light The present application relates to a vehicle light and a vehi-cle including a vehicle light.
Vehicles typically include a variety of types of vehicle lights. Vehicle lights, for example headlights, may be used to improve the view of the driver during darkness, or, in the case of brake lights or turn signal lights, to provide an in-dication of the movement or intended movement of the vehicle to other road users. A road vehicle typically includes head-lights, turn signal lights, brake lights, tail lights, at least one reversing light and may also include fog lights.
These lights may include an incandescent lamp or one or more light emitting diodes (LEDs) as the light source.
DE 10 2007 016 442 Al discloses a LED light for a vehicle with a holder element, a reflector and a covering lens. The LED light also includes a heat reserve integrated into the holder element which is positioned between the reflector and covering lens of vehicle light. The heat reserve can be used to heat the covering lens so as to prevent fogging of the covering lens. The heat reserve may also be used to de-ice the covering lens.
However, further improvements are desirable in order to pro-vide reliable defogging and/or de-icing of vehicle lights.
The application provides a vehicle light comprising a light source positioned within a first chamber and a control circuit for controlling the light source. The control circuit is posi-tioned in a second chamber that is separate from the first chamber. The vehicle light also comprises at least one face comprising a double wall defining a cavity. The second chamber is in flow communication with the cavity defined by the double wall.
This arrangement enables heat generated by the control circuit to be directed into the cavity defined by the double wall.
This heat can heat up the two walls of the double wall and, therefore, heat up at least this face of the vehicle light.
This increase of the temperature of the at least one face can be used to prevent fogging and/or can be used to defog or de-ice the vehicle light.
The first chamber may be described as the optical unit and the second chamber as the control unit of the vehicle light. The first and second chamber each define a volume that it separate from the volume of the other chamber. The two chambers typi-cally abut one another and have a common face. The electrical connection between the light source and the control circuit can penetrate through the common face.
In an embodiment, the light source comprises one or more light emitting diodes (LEDs) and, in particular, one or more semi- conductor light emitting diodes. Light emitting diodes typi-cally emit less heat than incandescent light bulbs. The heat emitted from the light emitting diodes may be insufficient to reliably defog or de-ice the covering lens of the vehicle light. The vehicle light according to the present application uses the heat generated by the control circuit that controls the light source to provide a vehicle light with an integral defogging and/or de-icing function. Therefore, an additional de-icing component is not required for a light source compris- ing one or more light emitting diodes should the light emit- ting diodes themselves emit insufficient heat to provide suf-ficient defogging or de-icing of the lens.
The vehicle light may also comprise a plurality of light emit-ting diodes arranged in banks, typically, a regular array of LEDs arranged in rows and columns. Each of the light emitting diodes may emit light of the same wavelength or they may emit light of differing wavelengths so as to provide light having a particular colour, for example, white light for the headlamps of the vehicle.
In one embodiment, the double wall comprises two transparent plates spaced apart from one another to define the cavity. In this embodiment, the double wall may provide at least a por-tion of the outer lens of the vehicle light through which the light source is emitted or may provide the entire outer lens of the vehicle light. In this case, the vehicle lights in-cludes a double wall outer lens.
The vehicle light may comprise an outer lens and a casing. In this embodiment, the double wall may provide a portion of the outer lens, or the entire outer lens, and/or at least a por-tion of the casing. If the double wall provides portion of the casing, the casing can be heated up by heat emitted from the control circuit and this heat may be conducted into the outer lens of the vehicle light. In this case the outer lens may comprise a single wall. This has the advantage that the light emitted from the vehicle light is not undesirably refracted and/or reflected by an outer lens comprising two walls of the double wall defining the cavity.
In one embodiment, the first chamber is defined by a first casing, at least one reflector and a first lens opposing the reflector. The first chamber may be hermetically sealed so as to prevent oxidation of the reflector and/or the light source.
Since the control circuit is positioned in a second chamber that is separate from the first chamber, the control circuit can be positioned in a second chamber comprising one or more through holes which may be used to encourage an air flow through the second chamber and encourage the heat generated by the control circuit to be directed from the control circuit into the cavity defined by the double wall. Since the first chamber is hermetically sealed, the air flow does not enter the first chamber and does not encourage the oxidation of the reflector and/or light source.
The first lens of the first chamber may provide an inner wall of the double wall defining the cavity and may provide an in- ner transparent wall of a double walled outer lens of the ve-hicle light.
The outer wall of the double wall may be provided by an outer lens of the vehicle light.
The cavity may have a uniform cross-section or may have a non-uniform cross-section in order to encourage increased air flow in some regions of the cavity compared with other regions of the cavity.
The control circuit for controlling the light source may com- prise heat generating components such as transistors and re- sistors. The vehicle light may also comprise convection pro- ducing means for directing an air flow over the control cir-cuit and into the cavity defined by the double wall.
The convection producing means may be provided by the form of the second chamber and/or form of the cavity defined by the double wall. For example heat generated by the control circuit would tend to rise upwardly. Therefore, the second chamber and/or double wall structure may include openings to enable air from the outside to enter and exit the second chamber. The second chamber may also include restrictions to encourage the flow of the naturally rising heat into the cavity defined by the double wall structure.
Alternatively, or in addition, the convection producing means may comprise a fan. This fan may be positioned within the sec-ond chamber or adjacent the second chamber so as to direct an air flow over the control circuit and into the cavity defined by the double wall.
The second chamber and the double wall may be arranged to pro-vide a sealed cavity in which the air flow can be continuously recirculated. This arrangement has the advantage that the air-flow can be repeatedly heated by repeatedly passing over the control circuit. This can lead it to a gradual rise in tem- perature of the air flow, depending on the amount of heat pro-duced by the control circuit and the heat loss from the air flow due to the heating of the double wall structure.
In further embodiment, the second chamber comprises at least one opening providing an inlet for the air flow. The double wall may also comprise at least one opening that provides an outlet for the airflow. If both of these openings are pro- vided, the air may flow into the second chamber, over the con- trol circuit, thus picking up heat, and into the cavity de-fined by the double wall where it releases the heat, thus heating the double wall and providing defogging and/or de-icing or preventing fogging of the double wall and outer lens of the vehicle light.
The first and second chambers of the vehicle light may have different spatial arrangements with respect to one another de-pending on the design of the vehicle light and the available space for the vehicle light within the vehicle.
In one embodiment, the second chamber is positioned behind the first chamber so that it is positioned on the opposing side of the vehicle light to the outer lens. The second chamber may be positioned directly behind the reflector of the first chamber on the optical axis of the vehicle light. In a further embodi-ment, the second chamber is positioned adjacent the optical axis of the vehicle light and may be positioned underneath or above the first chamber.
The vehicle light according to any one of the embodiments de-scribed above may be adapted to provide any required light for the vehicle. For example, the vehicle light may be a head-light, a brake light, a tail light, a reversing light, a fog lights or a turn signal light.
In a further embodiment, the application provides a vehicle including at least one light according to one of the previ-ously described embodiments.
Particular embodiments will now be described with reference to the accompanying drawings.
Figure 1 illustrates a vehicle light according to a first embodiment, Figure 2 illustrates a vehicle light according to a sec-ond embodiment.
Figure 1 illustrates a vehicle light 1 according to a first embodiment. The vehicle light 1 comprises a light source 2 po-sitioned within a first chamber 3 and a control circuit 4 for controlling the light source 2. The control circuit 4 is posi-tioned in a second chamber 5 that is separate from the first chamber 3. The first chamber 3 may be described as the optical unit and the second chamber 5 as the control unit of the vehi-cle light 1.
The first chamber 3 abuts the second chamber 5 so that the first chamber 3 and second chamber 5 have a common face 19.
The electrical connection between the light source 2 and the control circuit 4 penetrates through the common face 19.
In this embodiment, the light source 2 comprises a plurality of semiconductor light emitting diodes of which only one is illustrated in the view of Figure 1. The vehicle light 1 fur-ther comprises at least one face 6 comprising a double wall 7 defining a cavity 8. The double wall 7 comprises two transpar- ent plates 9, 10 spaced at a distance from one another to de- fine a cavity 8 having a uniform cross-section. The two trans-parent plates 9, 10 comprise plastic and provide the outer lens 18 of the vehicle light 1. The vehicle light 1 also corn- prises a casing 21 which together with the outer lens 18 de-fines the outermost surface of the vehicle light. The vehicle light also has connectors 22 which enable power to be supplied to the control circuit from an external source such as a vehi-cle battery.
The second chamber 5 is in flow communication with the cavity 8 whereas the first chamber 3, in which the light source 2 is accommodated, is hermetically sealed over the second chamber 5 and the cavity 8 defined by the two walls 9, 10 of the double wall 7.
The first chamber 3 comprises a casing 11 positioned between a lens 12 which provides the inner wall 10 of the double wall 7 of the face 6 and a reflector 13. The reflector 13 may be alu-minium coated plastic, for example. In further non-illustrated embodiments, the first chamber 3 comprises a plurality of re-flectors. The first chamber 3 is hermetically sealed so as to avoid oxidation of the reflector 13 and the light emitting di-odes 2.
The vehicle light 1 comprises an integrated defogging and/or de-icing function since heat emitted from the control circuit 4 in the second chamber 5 is directed into the cavity 8 de-fined by the double wall 7. This heat is able to heat up the two walls 9, 10 of the double wall 7 which provides the outer lens of vehicle light 1. This heating of the two walls 9, 10 can prevent fogging of the outer lens 18 of the vehicle light 1 and/or provide defogging and/or de-icing of the outer lens 18 of the vehicle light 1. The outer wall 9 of the double wall 7 may be provided by a transparent lens of the vehicle light 1.
In order to increase the defogging and/or de-icing ability of vehicle light 1, the vehicle light 1 also comprises a convec-tion producing means to direct an air flow over the control circuit 4 and into the cavity 8 as indicated by the arrows 17 in figure 1. In this embodiment, the convention producing means is a fan 14 positioned in the second chamber 5 which di-rects the air flow over the control circuit 4 and into the cavity 8.
In this embodiment, the second chamber 5 includes an opening and the double wall 7 includes an outlet 16 so that air can be directed from the environment, through inlet 15, through the second chamber 5, into the cavity 8 and out of the double wall structure 7 through the outlet 16 as indicated by the ar-rows 17.
Therefore, heat, indicated by arrow 20, that is generated by components of the control circuit 4 may be efficiently used to defog the outer lens 18 provided by the double wall 7 of the vehicle light 1. This arrangement is useful in vehicle lights including light emitting diodes which themselves may not emit sufficient heat to provide sufficient defogging and de-icing of the outer lens 18 of the vehicle light 1.
The air flow indicated by arrows 17 is, therefore, used to di- rect the heat from the heat generating components of the con-trol circuit 4 to the outer lens 18 so that it can be used there efficiently to provide defogging. At the same time, the first chamber 3 providing the optical unit of the vehicle light 1 may remain hermetically sealed so as to prevent oxida-tion of the reflector 13 and the light emitting diodes so as to not decrease the working life time of the vehicle light 1 due to the additional airflow. Since the defogging function is integral to the vehicle light 1, further additional defogging and/or de-icing components are not required.
Figure 2 illustrates a vehicle light 1' according to a second embodiment. The second embodiment differs from the first em-bodiment in the relative position of the control circuit 4 and first chamber 3. In the second embodiment, the control circuit 4 is positioned beneath the first chamber 3 so that the plu-rality of light emitting diodes 2 are mounted on the base of the casing 11 of the first chamber 3. The electrical connec- tions between the light emitting diodes 2 and the control cir-cuit 4 penetrate through the base of the casing 11. The second chamber 5 extends from underneath the first chamber 3 around the rear side of the first chamber behind the reflector 13 to an entrance to the cavity 8 providing the outer lens 18 of the vehicle light 1' Heat and, if desired, a forced air flow as indicated by the arrows 20 and 17, respectively, are directed from the heat generating components of the control circuit 4 upwardly behind the reflector 13 and into the cavity 8 is defined by the dou-ble wall 7 providing the outer lens of the vehicle light 1' The air flow exits the cavity 8 through opening 16 at the bot-tom most portion of the cavity 8 after having given up heat to heat the two walls 9, 10 providing the double walled outer lens 18 and providing defogging and/or de-icing of the outer lens 18 of the vehicle light 1' The vehicle light 1 according to the first embodiment and the vehicle light 1' according to the second embodiment may be used as a headlight or a brake light or a tail light or a re- versing light or a fog light or a turn signal light of a non-illustrated vehicle such as a road vehicle.
