Reflect housing, shield, lens, light-emitting component) loading, be to carry on the substrate 11, in addition, thermally conductive pathways are also by same
Carried out under one substrate framework, and respectively can not effectively reach the effect that heat conduction path separates with loading structure.Furthermore
Because the first light-emitting component in M536321 Patent Cases and the distance between the second luminescent element surface are wider, therefore, in order to
Lift the luminous efficiency of dipped headlight, the light-emitting area of the first light-emitting component 12 must fixed part 19 central axis (axis of reference,
Reference axis) near, this measure will cause the light-emitting area of the second light-emitting component 13 away from existing halogen tungsten lamp, Halogen lamp LED or
The distance filament position of HID lamps, and cause the luminous efficiency of high beam poor.
