  • the present invention relates to an automotive light bulb comprising a carrier arrangement comprising a first main surface and a second main surface opposite the first main surface, a first plurality of solid state lighting elements on the first main surface and a second plurality of solid state lighting elements on the second main surface.
  • the present invention further relates to a luminaire including such an automotive light bulb.
  • SSL element-based devices In many lighting applications, traditional incandescent light bulbs are replaced by more energy-efficient alternatives, in particular by solid state lighting (SSL) elements such as semiconductor light emitting diode (LED) devices. Apart from being more energy-efficient, such SSL element-based devices tend to have a superior lifetime compared to incandescent light bulbs, with lifetime improvements by a factor of about 10 being achievable. In addition, the colour temperature of SSL element-based devices can be easily tuned to a colour temperature of 4,000K or above, which gives the device a desirable cool colour.
  • SSL solid state lighting
  • SSL element-based devices for instance make such devices particularly attractive for automotive lighting applications.
  • automotive light bulbs must produce homologated light outputs, i.e. light outputs that comply with required safety standards. This is a far from trivial exercise, as the output characteristics of SSL elements are completely different to the output characteristics of incandescent light bulb filaments.
  • a SSL-based device typically must contain a large number of SSL elements as the output intensity of a single SSL element is much smaller than that of an incandescent light bulb filament.
  • SSL elements produce a beam angle of 180° whereas filaments tend to generate omnidirectional light, i.e. emit light over the full 360° range.
  • beam shaping elements e.g. for glare-reducing purposes such as the light-blocking cap on automotive light bulbs such as H7, H8, Hl l, H16, HB4 sized light bulbs and so on can be easily mounted on the glass housing. This is not as straightforward for SSL-based devices where encapsulation of the SSL elements may be undesirable for cooling purposes. Overheating of the SSL elements may cause an unwanted change in the colour temperature of the light bulb and may reduce its lifetime.
  • CN 2026918423 U discloses an automotive light bulb comprising LEDs on opposite sides of a heat sink plate.
  • This light bulb does not produce a homologated light output such that additional beam shaping measures have to be taken in the luminaire, e.g. the vehicle lens unit in which the light bulb is placed. This is undesirable as it is costly and makes the lens unit suitable for a particular type of automotive light bulb only, thus hampering the replacement of the automotive light bulb in case of a light bulb failure.
  • the present invention seeks to provide an SSL element-based automotive light bulb capable of producing a homologated light output.
  • the present invention further seeks to provide a luminaire including such a light bulb.

  • Such a light bulb is capable of producing an omnidirectional luminous output of high intensity due to the presence of a plurality of SSL elements on opposite carrier surfaces whilst at the same time producing a homologated output due to the glare-reducing light shielding arrangement, which mimics the light blocking cap of automotive light bulbs such as H7, H8, HI 1, HI 6, HB4 sized light bulbs and the like.
  • the light shielding arrangement may form part of the carrier arrangement.
  • the glare -reducing light shielding arrangement comprises a glare-reducing light shielding member mounted on the distal end of carrier arrangement.
  • the light shielding arrangement may be separate to the carrier arrangement.
  • the automotive light bulb further comprises a heat sink portion extending from the main body and enveloping the carrier arrangement, the heat sink portion comprising a first recess exposing the first plurality of solid state lighting elements and a second recess exposing the second plurality of solid state lighting elements, wherein each of the first recess and the second recess comprises a side wall at a distal end of the heat sink portion, wherein said side walls define the glare-reducing light shielding arrangement.
  • the glare -reducing light shielding arrangement preferably is arranged to block luminous output generated at an angle in the range of 0° to at least 20° with the first main surface and second main surface respectively to ensure that the light output of the automotive light bulb is homologated. More preferably, light generated under an angle of up to 35° with the first main surface and second main surface respectively is blocked by the glare -reducing light shielding arrangement.
  • the main body forms part of a heat sink arrangement, which may further include the heat sink portion. This further improves the cooling of the SSL elements of the automotive light bulb.
  • the carrier arrangement may comprise a single printed circuit board comprising the first main surface and the second main surface opposite the first main surface. This yields a very compact automotive light bulb.
  • the carrier arrangement may comprise a first printed circuit board comprising the first main surface and a second printed circuit board comprising the second main surface opposite the first main surface for the sake of manufacturing simplicity.
  • a heat sink plate extending from the main body may also be present, wherein the first printed circuit board and the second printed circuit board are mounted on opposite sides of the heat sink plate to further improve heat transfer from the SSL elements.
  • Each printed circuit board preferably has a thickness of 3 mm or less in order to mimic the diameter of a traditional incandescent or halogen automotive light bulb filament, which ensures that a similar beam pattern is produced.

This ensures that main body reflects or absorbs a small part of the luminous output of the automotive light bulb only, which ensures that the automotive light bulb closely mimics the emissive characteristics of a filament of an incandescent light bulb.
  • the main body may house a driver circuit for driving the solid state lighting elements. This obviates the need for a separate driver circuit and contributes to the compactness of the overall automotive lighting arrangement.
  • Each of the solid state lighting elements preferably has a luminous area having a width not exceeding 4 mm such that sufficient solid state lighting elements can be placed along a length that is similar to the length of a traditional incandescent or halogen automotive light bulb filament, which ensures that a similar beam pattern is produced.
