Abstract
An LED vehicular lamp with reflector can include a plurality of LED modules each having respective appropriate light distributions. The modules can be attached to a housing to form a light distribution characteristic though combination of the light emitted from the LED modules. At least part of the LED modules can include an illumination axis that is substantially at a right angle to the optical axis of the lamp such that light reflected at a reflector provided in the housing travels in the illumination direction of the LED light source vehicular lamp. The LED modules can also include a rear end that protrudes from an outer surface of the housing to improve the heat radiation efficiency, which enables the use of LED chips that can use higher permissible current values.
