Definitions

  • the present invention relates to a heat transfer system for a lighting module of a motor vehicle.
  • the invention also relates to a motor vehicle lighting device comprising such a lighting module.
  • lighting modules comprising a light source using LEDs (light-emitting diodes) is known.
  • Such system lighting modules using light source comprising LEDs makes it possible to provide proper lighting in front of the vehicle. They are therefore used to perform various functions such as for example road lighting function to illuminate the path and also avoid dazzling other motorists, or for signaling functions.
  • such a lighting module can become very hot due to the use of LEDs and the heat generated by the motor compartment. Excessive heating leads to malfunction of the LED or even destruction of the system and/ or the control circuit. It is therefore needed to cool the lighting module, in order to keep the LED under their junction temperature, above which their performance is decreasing.
  • the use of heatsinks with airfoils or fins is known.
  • such cooling means are not always sufficiently efficient in maintaining the lighting module below a damaging temperature.
  • active cooling with fans blowing air toward the fins of the heat sink or anodization or cataphoresis.
  • Patent such as KR 20160000832 U and US 2008175008 A1 .
  • This prior art discloses surface treated led lamp by arc plasma anodizing and also improvement of heatsink radiation by vacuum sputtering, vaporization and anodizing respectively. Both the prior art document, talk about anodizing of all the fins of the heat sink. Such methods are complicated in nature and therefore costly.
  • EP 2 762 771 A2 and US 2011/068687 A1 disclose further lighting modules of the prior art.
  • An object of the present invention is to solve at least partially the disadvantages described above of known lighting module.
  • a lighting module for an automotive vehicle comprising a light source for producing a light beam in front of the vehicle.
  • the lighting module further comprises a heat exchange system for transferring heat away from the light source, the heat exchange system.
  • the heat exchange system has a heat sink plate and plurality of heat transfer airfoils thermally connected to the heat sink plate.
  • the heat transfer airfoils of the heat exchange system have a plurality of non-anodized heat transfer airfoils and a pair of anodized heat transfer airfoils.
  • the pair of anodized heat transfer airfoils are at peripheral portion encompassing the plurality of non-anodized airfoils of the heat exchange system. Indeed, such an arrangement wherein only peripheral airfoils are anodized has shown to decrease significantly the junction temperature compared to a heat exchange system without any anodized airfoils and is quite as efficient than a full set of anodized airfoils, for a much better production cost.
  • the heat sink plate of the heat transfer system is provided with an enveloping airfoil over the plurality of non-anodized heat transfer airfoils and the pair of anodized heat transfer airfoils.
  • the enveloping airfoil of the embodiment of the present invention is connected on the anodized heat transfer airfoil at peripheral portion of the heat exchange system.
  • the enveloping airfoil is also anodized to improve the heat transfer. This arrangement increases further the heat transfer efficiency, while still limiting the cost compared to a full set of anodized airfoils.
  • one of the heat transfer airfoil is provided at peripheral portion is orientated towards the visible side of the lighting module.
  • the heat transfer airfoil oriented towards the visible side of the lighting module is anodized to improve the heat transfer.
  • the anodized heat transfer airfoil are provided with a thin plastic coating to improve the heat transfer and the aesthetic of the lighting module, when considering the heat transfer airfoil oriented towards the visible side of the lighting module.
  • the thin plastic coating provided on the heat transfer airfoil is lower than 100 microns.
  • Figure 1 shows a perspective view of a heat exchange system 100 of lighting device having a light source 10 such as LED for producing a light beam, according to an embodiment of the present invention.
  • a light source 10 such as LED for producing a light beam
  • the heat exchange system (100) shown in Figure 1 comprises a heat sink plate (11) provided with a plurality of heat transfer airfoils for transferring heat away from the heat sink plate 11.
  • the lighting module is provided with such heat exchange system for reducing heat generated inside the module.
  • Such heat sink plate are provided with plurality of airfoils to increase heat convection dissipation.
  • surface treatment such as anodization or cataphoresis is done to increasing radiation emissivity of the airfoils. But the only surface where this emissivity improvement is useful is the outer surface because of the emission of inner airfoils is compensated by the emission of its in front airfoils.
  • the pluralities of heat transfer airfoils of heat exchange system 100 of the present invention are made of two types.
  • the heat exchange system 100 is provided with a plurality of non-anodized heat transfer airfoils 14 and a pair of anodized heat transfer airfoils 12.
  • the pair of anodized heat transfer airfoils 12 is placed at peripheral portion of the heat sink plate 11.
  • the pair anodized heat transfer airfoils 12 are arranged such that they encompass the plurality of non-anodized heat transfer airfoils 14 of the heat exchange system 100.
  • the plurality of non-anodized heat transfer airfoils 14 and the pair of anodized heat transfer airfoils 12 are thermally connected to the heat sink plate 11 and radiate outwards.
  • Comparative test showed that the design according to the invention allowed a decrease of 14.5 °C of the junction temperature of the LED compared to a heat sink plate provided with a full set of non anodized airfoils whereas a full set of anodized airfoils allowed to achieve a decrease of 18°C of the junction temperature of the LED.
  • FIG. 2 shows another embodiment of the present invention.
  • the heat transfer system 100 comprises a heat sink plate 11, a plurality or non-anodized heat transfer airfoil 14 and a pair of anodized heat transfer airfoils 12. Additionally, the heat transfer system 100 comprises an enveloping airfoil 16. The enveloping airfoil 16 is connected on the pair of anodized heat transfer airfoil 12 provided at peripheral portion of the heat exchange system (100). The embodiment provides emissivity improvement on the outer side of this surface. The enveloping airfoil 16 of the present invention is also anodized to attain the objectives according to the scope of invention.
  • At least one anodized heat transfer airfoil 12 at peripheral portion is orientated towards the visible side of the lighting module.
  • the Figure shows a light source 10 such as a LED assembled inside the housing 20 of a motor vehicle lighting device.
  • the figure also shows the heat sink plate 11 arranged in relation to the light source 10. The provision of the anodized airfoil in the visible area of the lighting device provides higher heat dissipation due to relatively lower temperature near the outer side of lighting device.
  • Figure 4 shows another embodiment of the present invention where the at least one anodized heat transfer airfoil 12 , for instance here the one provided at peripheral portion, is coated with a thin plastic coating 12a.
  • the size of the thin plastic coating 12a provided on the heat transfer airfoil 12 is lower than 100 microns.
  • the thin plastic coating 12a is provided with additional aesthetic design or feature to improve the design of the lighting module. The addition of the thin plastic coating 12a further improves the emissivity of the heat sink and ensures better heat transfer in the lighting module.
