Patent ID: 8057075

Claim:
A lamp device comprising: a housing including first and second ends spaced in an axial direction, with the first end including an electrical connection portion, with the second end including a light transmitting portion, with the housing further including an air inlet portion adjacent to the electrical connection portion and an air outlet portion adjacent to the light transmitting portion, with each of the air inlet portion and the air outlet portion extending from an inner periphery through an outer periphery of the housing with both of the air inlet and outlet portions communicate inside and outside of the lamp device; a circuit board mounted in the housing and electrically connected to the electrical connection portion, with the circuit board including a substrate having first and second sides spaced in the axial direction, with the first side of the substrate facing the second end of the housing, with the second side of the substrate facing the first end of the housing, with the substrate disposed in a position out of a region between the air inlet and outlet portions, with the circuit board further including a plurality of electronic elements mounted on at least one of the first and second sides of the substrate, with each of the plurality of electronic elements having a height in the axial direction, with one of the plurality of electronic elements having the largest height in the axial direction being mounted on the first side and extending toward the second end of the housing; a heat dissipating module mounted in the housing and between the air inlet portion and the air outlet portion; and a lighting element coupled to the heat dissipating module and electrically connected to the circuit board.
