Abstract
A vehicular head lamp includes a first light source module having a plurality of semiconductor light emitting elements and a second light source module connected in series to the first light source module, having semiconductor light emitting elements the number of which is smaller than that of the first light source module and generating the light of brightness higher than that of the first light source module when an electric current substantially equal to that of the first light source module is supplied.
Claims4
A vehicular headlamp comprising:
- a first light source module having a plurality of semiconductor light emitting elements and
- a second light source module connected in series to the first light source module, having at least one semiconductor light emitting element the number of which is smaller than that of the first light source module and generating the light of brightness higher than that of the first light source module when an electric current substantially equal to that of the first light source module is supplied.
A vehicular headlamp comprising:
- a first light source module having a plurality of semiconductor light emitting elements and
- a second light source module connected in parallel with the first light source module and having at least one semiconductor light emitting element the number of which is smaller than that of the first light source module,
- wherein when voltage substantially equal to that of the first light source module is applied to the second light source module, a larger quantity of electric current is supplied to the semiconductor light emitting element of the second light source module than a quantity of an electric current supplied to the semiconductor light emitting elements provided in the first light source module.
