ILLUMINATING DEVICE OF A VEHICLE

HERO MOTOCORP LIMITED, an Indian Company at: The Grand Plaza, Plot No.2, Nelson Mandela Road, Vasant Kunj- Phase -II, New Delhi, India, 110 070

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION:
[01] The present invention relates to an illuminating device of a vehicle. In particular, the invention relates to at least one of a tail light device and a head light device of a vehicle.

BACKGROUND OF THE INVENTION:
[02] Conventionally, a vehicle comprises at least one illuminating device and in particular includes a head light device and a tail light device.

[03] A conventional head light device includes at least one low beam projector unit, and at least one high beam projector unit. Each of the low beam projector unit and the high beam projector unit may comprise a halogen lamp, a discharge lamp, or a semiconductor lighting device as a light source, and light emitted from the light source is irradiated to the front side of the vehicle.

[04] A conventional tail light device includes at least one stop function indicating lamp unit, and a vehicle rear facing lamp unit. Each of the at least one stop function indicating lamp unit and the vehicle rear facing lamp unit may comprise a halogen lamp, a discharge lamp, or a semiconductor lighting device as a light source, and light emitted from the light source is irradiated to the back side the vehicle.

[05] The automotive industry is increasingly providing semiconductor lighting device and more particularly light emitting diodes (LED) as the light source in the head light device and in the tail light device. However, when LEDs are provided as light source in the head light device and the tail light device, one or more of the following issues arise, still need to be addressed. For instance, in a conventional tail light device the vehicle rear facing lamp unit serves singular purpose. Thus, to attain additional functionalities, additional vehicle rear facing lamp units are needed to be provided, which leads to an increase in an amount of heat generated by the tail light device, an increase in a cost of the tail light device, and an increase in a size of the tail light device. Also, creation of uniform light pattern by each of the stop function indicating lamp unit and the vehicle rear facing lamp unit, which are distinguishable is a substantial challenge.

[06] Likewise, in a conventional head light device, the at least one low beam projector unit, and the at least one high beam projector unit is provided as part of the vehicle head light device while vehicle front facing lamp units are provided as a separate units. Many attempts have been made to include the at least one low beam projector unit, the at least one high beam projector unit, and at least one vehicle front facing lamp unit as part of the vehicle head light device. However, sizing of the head light device, creation of uniform low beam pattern, creation of low beam pattern of a needed shape, creation of uniform high beam pattern, creation of high beam pattern of a needed shape, creation of uniform light pattern by the vehicle front facing lamp units, creation of desired shapes for the vehicle front facing lamp units, maintaining an amount of heat generated below a predetermined level, are issues that still need addressing.
