Definitions
- the invention relates to a headlamp, in particular a motor vehicle headlamp with the features of the preamble of claim 1.
- Such a headlight is known for example from the publication with the publication number DE 102 13 680 AI.
- a cooling circuit is provided, in which the air heated by the illuminant is sucked out of the housing of the headlight by means of a pressure unit, it is a blower, and is passed over a heat exchanger to cool the air. At the heat exchanger, the air is then transported back into the headlight housing.
- a disadvantage of the headlamp disclosed in the publication is that regardless of the temperature that the air has in the housing headlamp and regardless of the current cooling capacity of the heat exchanger, the pressure unit is switched on with the same output.
- the cooling capacity of the heat exchanger depends to a large extent on the temperature and the flow rate of the cooling medium with which the heat exchanger is flown to cool the air transported in the cooling circuit. Due to the constant operation of the printing unit, printing units with a long service life are required, which leads to increased costs.
- the invention is therefore based on the object of proposing a headlight in which the printing unit is not so heavily used.
- Such a headlight has a means for regulating and / or controlling the printing unit.
- the means for regulating and / or controlling the pressure unit can be used to set the output of the pressure unit in accordance with the temperature of the air circulated in the headlight or the secondary-side cooling medium and / or in accordance with the flow velocity on the secondary side of the heat exchanger.
- Such a headlight advantageously has at least one sensor for the flow rate and / or one
- Temperature sensor which is connected to the means for controlling and / or regulating. Depending on the flow velocity measured by the sensor or the temperature measured by the temperature sensor, the means for controlling and / or regulating the output of the
- Adjustable pressure unit For example, the ambient air can flow against the secondary side of the heat exchanger, the flow speed changing as a function of the speed of the motor vehicle in which the headlight can be installed.
- the air in the headlamp must be circulated at a higher speed than, for example, when the outside temperature is lower and the vehicle's speed is very high.
- Temperature sensors can also be suitable to the
- a housing of the heat exchanger, a holder for the pressure unit and a housing of the pressure unit can preferably be produced from the same plastics as a housing of the headlamp itself.
- the material can be PP-TV, for example.
- the housing of the heat exchanger and the housing of the blower can be an integral part of the housing of the headlamp. Furthermore, it is advantageous if a possibility is provided in the heat exchanger for removing liquid which precipitates in the housing of the headlight.
- a drainage opening provided for this purpose can simultaneously serve as a pressure compensation opening for the headlight housing.
- the heat exchanger can be connected to a low-temperature cooling circuit, for example of an air conditioning system.
- a headlight is also known from the prior art, in which the air flow is directed in such a way that it is directed past the lamps and / or heat sinks of the lamps. This results in better heat dissipation from the lamps and the heat sinks.
- the headlight as disclosed in the publication DE 198 14 300 AI, has passage openings in its housing, which enables an air exchange between the surroundings of the headlight and the headlight interior. For example, when the motor vehicle is traveling, the headlight can flow against the headlight, which then enters the housing of the headlamp, is guided past the illuminants in order to cool them and then exits again through further openings.
- a disadvantage of this headlight is that moisture and dirt can penetrate into the headlight through the openings in the housing. However, this is not desirable.
- the invention is therefore also based on the object of developing the headlight known from the publication DE 198 14 300 in such a way that moisture can no longer enter the headlight housing.
- Such a headlamp has, in addition to the features mentioned in the preamble of claim 1, a first air guide section, a second air guide section, a third air guide section, first lamps and second lamps.
- the first air guide section is connected to the pressure side of the pressure unit in terms of flow technology.
- the first illuminants are arranged on a first separating element which has passage openings in the region of the first illuminants for fluidic connection of the first air guide section to the second air guide section. Otherwise, the first separating element separates the first air guide section from the second air guide section.
- the second illuminants are arranged on a second separating element which has passage openings in the region of the second illuminants for fluidic connection of the second air guide section to the third air guide section. Otherwise, the second separating element separates the second air guide section from the third air guide section.
- the third air duct section is also Fluidically connected to the suction side of the pressure unit via the heat exchanger.
- the invention makes use of the more extensive knowledge to use that not all lamps must be cooled equally by the parallel • heat exchanger cooled air. It is therefore quite possible to group lamps in such a way that the first lamps are flowed to first, while only then the second lamps are flowed with with the air already heated by the first lamps.
- the air guide sections arranged one behind the other are provided in the invention.
- All or part of the air guide sections can be formed by one or more air guide channels. These air guide channels can in turn be formed by pipes and / or hoses.
- the first illuminants and / or the second illuminants can be arranged in the passage openings of the first separating element or the second separating element or can protrude into these passage openings.
- the first lamps and / or the second lamps can also be connected to a heat sink.
- the heat sinks can then be arranged in the passage openings of the separating elements or protrude into these passage openings.
- the first separating element and / or the second separating element can be arranged pivotably in the housing, so that it is possible to pivot the first and / or the second illuminants in the housing in order to change the direction from which Headlights emerging light to change, for example, for headlight range control.
- individual illuminants can also be pivotally mounted on the separating elements. This can be advantageous for a headlight with a so-called cornering light.
- FIG. 1 is a schematic representation of a first headlight according to the invention in section
- FIG. 2 is a schematic representation of a second headlight according to the invention in section
- FIG. 3 shows a lamp arranged pivotably in a headlight according to the invention
- FIG. 5 shows a heat exchanger of a further headlight according to the invention
- FIG. 6 shows a section through an inner tube of a heat exchanger according to FIG. 5 in an alternative embodiment
- 7 shows a section through the inner tube of a heat exchanger according to FIG. 5 in a further alternative embodiment.
- the headlamp according to the invention shown in FIG. 1 has a housing 13, 14 which consists of a lower housing part 13 and an upper housing part 14, the upper housing part being transparent and allowing the light generated by lamps 6, 7 to emerge from the headlamp housing 13, 14 ,
- An outlet opening for a heat exchanger 2 is provided in the lower housing part.
- the heat exchanger 2 serves to remove the heat generated by the lamps 6, 7 when the light is generated from the housing of the headlight 6, 7.
- the heat exchanger 2 is connected to the suction side of a pressure unit 1, in the present case it is a blower.
- the pressure side of the pressure unit 1 is connected to a first air guide section 3 of the headlight.
- the air guiding area 3 is delimited by a tube 11 and first separating elements 8, which separate the first air guiding area 3 from a second air guiding area 4.
- the first air guide area 3 is connected to the second air guide area 4 only through passage openings 10 in the first separating element 8.
- Heat sinks 12 connected to the first illuminants 6 are arranged in the passage openings 10, or the heat sinks 12 partially protrude into the passage openings 10.
- Lenses 15 are assigned to the first illuminants 6, which bundle the light generated by the first illuminants 6 and direct them in the direction of the transparent housing upper part 14.
- the air sucked in by the pressure unit 1 from the heat exchanger 2 can be blown past the heat sinks 12 and the first illuminants 6 and into the second air duct region 4 through the through openings 10 during operation of the pressure unit via the first air duct region 3.
- the cool air sweeps past the heat sink 12 of the first lamps 6 and past these lamps 6 and dissipates heat from the heat sink 12 or the first lamp 6.
- a third air guiding area 5 is provided.
- This third air guiding area 5 is delimited by a tube 11 and a second separating element 9.
- the second separating element 9 has through openings 10.
- Illuminants, namely second illuminants 7, are also arranged in these passage openings 10. These second illuminants are also connected to a heat sink 12, which protrude into the passage openings 10 of the second separating element 9.
- One of these second illuminants 7 is assigned a reflector 16, which bundles the light generated by this second illuminant 7 and directs it in a desired direction.
- the remaining second illuminants 7 are assigned lenses 15, which bundle the light from these illuminants 7 and guide them in the direction of the transparent housing upper part 14.
- the third air guiding area 5 is not only connected to the second air guiding area 4, but also - as already stated - to the heat exchanger 2. This creates a closed circuit for the air. From one side of the heat exchanger 2, the cold air via the pressure unit through the first air guide area 1 on the first lamps 6 transported past in the second air guide area 4. The air absorbs heat generated by the first lamps 6. The air is then transported from the second air guide area 4 past the second illuminants 7 through the passage openings 10 into the third air guide area 5. The air already heated by the first lamps 6 sweeps past the second lamps 7 and the heat sinks 12 assigned to these second lamps 7 and also absorbs heat from these lamps 7.
- the air which has been heated further in this way, then reaches the other side of the heat exchanger 2 via the third air-guiding region 5.
- the air is extracted from the heat, so that cold air is again available in sufficient quantity on the cold air side of the heat exchanger to open up the lamps bring the desired operating temperature.
- the illuminants are light-emitting diodes, but in principle such a headlight is also conceivable with other illuminants.
- the headlight according to the invention shown in FIG. 2 has features that correspond at least in their function to the features of the headlight according to FIG. 1. These features are therefore the same in FIG. 2
- first separating element 8 and a second separating element 9 has a heat exchanger 2, a pressure unit 1, a first air guiding area 3, a second air guiding area 4, a third air guiding area 5, first illuminants 6, second illuminants 7, the illuminants assigned heat sink 12 and lenses 15, and a first separating element 8 and a second separating element 9.
- the first air guiding area 3 and the second air guiding area 4 are not bounded by a pipe. Rather, the first air guide area 3 and the third air guide area 5 are delimited by the housing 13 and the first separating element 8 or the second separating element 9. A third separating element 23, 24 further delimits the first air guiding area 3 from the third air guiding area 5 and vice versa.
- the first separating element 8, the second separating element 9 and a first part 23 of the third separating element 23, 24 are connected to one another in one piece.
- This overall separating element 8, 9, 23 thus formed is rotatably mounted in a pivot bearing 18 on the lower housing part 13 of the housing 13, 14. This enables the headlight to be adjusted, for example.
- Sealing areas 17 between the first separating element 8 or the second separating element 9 on the one hand and the lower housing part 13 on the other hand and a sliding connection between the first part 23 and a second part 24 of the third separating element 23, 24 ensure that even after or during pivoting of the
- the desired path of the air from the first air guide section 3 to the second air guide section 4 further into the third air guide section 5 is predetermined and a fluidic short circuit, for example, between the first
- Air guide section 3 and the third air guide section 5 is excluded, as is a direct transition of the air from the first air guide section 3 to the second air guide section 4, or from the second air guide section 4 to the third air guide section 5, bypassing the Through openings 10. This ensures the constant flow against the heat sink 12 or the first illuminant 6 and the second illuminant 7.
- FIG. 3 shows a first or second illuminant 6, 7 which is pivotably arranged in a first or second separating element 8, 9.
- two opposite tabs 25 are provided on the separating element 8, 9 and are arranged on both sides of the passage opening 10 of the separating element 8, 9.
- the heat sink 20, 21, which is assigned to the illuminant 6, 7, is rotatably attached to these tabs 25. Both the illuminant 6, 7 and the lens 15 assigned to the illuminant are then attached to this heat sink 20, 21.
- the heat sink 20, 21, 26 has a sleeve-like left section 26 which bears tightly against the separating element 8, 9 via a sealing region 27.
- the sealing region 27 between the separating element 8, 9 and the left section 26 is formed by a ball or cylindrical surface around the pivot axis 19 of the heat sink. This ensures that air which passes through the through openings 10 is passed through the left section 26 of the heat sink and not between the separating element 8, 9 and the left section
- Radial webs 21 are provided in the left section 26 of the heat sink 20, 21, 26.
- the illuminant 6, 7 is fastened to a core in the center of the heat sink.
- the left section 26 is followed by holding webs in a right section of the heat sink, to which the lens 15 is attached.
- a pivot lever 22 is articulated, via which a force can be exerted on the heat sink in order to To pivot the heat sink with the attachments attached to it about the pivot axis 19. It is thus possible to change the direction of the light generated by the lighting means 6, 7 by actuating the pivot lever 22. This may be necessary for dynamic cornering lights in motor vehicle headlights, for example.
- the heat exchanger of a headlamp according to the invention shown in FIG. 4 has first channels 31 and second channels 32 which are guided alternately side by side through the heat exchanger.
- the second channels 32 serve to transport the air circulated in the headlight, while the first channels 31 serve to receive air from the outside.
- the air taken in from the outside is passed through the heat exchanger in counterflow to the air circulated in the headlight and the second channels 32.
- the division into a plurality of first channels 31 and second channels 32 increases the surface area between the first channels 31 and the second channels 32, which enables efficient heat exchange between the channels 31, 32 in a small space.
- Very thin-walled metal sheets or plastic walls can be used between the channels in order to keep the heat transfer resistance as low as possible.
- the heat exchanger of a heat exchanger according to the invention shown in FIG. 5 has a first channel 31 through which the outside air is guided in order to cool the air circulated in the headlight through a second channel 32.
- the first channel 31 is formed by a tube (inner tube) which is surrounded concentrically by a second tube. This second tube is widened at its ends and also lies close to the first tube.
- the air circulated in the headlight is conveyed into and out of the intermediate space between the first tube and the second tube via lateral connections 32a, 32b.
- the air flows through the first channel 31 and the second channel 32 are transported in counterflow, so that an efficient cooling of the air circulated in the headlight is possible.
- the separation between the first and the second channel 31, 32 can also be formed by a ribbed, extruded hollow profile, as is shown in section in FIG. 6.
- this extruded hollow profile the surface between the first channel and the second channel is increased, which enables a more efficient heat exchange.
- a pipe folded from sheet metal can be used, as is shown in section in FIG. 7.
