Abstract
Five lamp units with light emitting elements are supported by a common metal made support member. Heat generated by the respective light emitting elements is transferred to the metal made support member having a large heat capacity to restrain a temperature rise thereof. The lamp units including the light emitting elements having a relatively large heat generating amount are arranged on lower sides of the lamp units including the light emitting elements having a relatively small heat generating amount.
