Abstract

A vehicle lighting device includes a lamp housing, a heat sink, a light source assembly, and a flexible member. The heat sink is disposed inside the lamp housing, and the light source assembly is disposed on the heat sink. The flexible member is inserted between and touches the heat sink and the lamp housing to form a heat dissipation path through the heat sink, the flexible member and the lamp housing in succession.

Description

technical field [0001] The invention relates to a lighting device, in particular to a vehicle lighting device with good heat dissipation efficiency. Background technique [0002] figure 1 It is a schematic diagram of a known vehicle lighting device. Such as figure 1 As shown, spot welding inside the lamp housing 102 of the vehicle lighting device 100 can form a plurality of flanges 102a. After the light source assembly 104 is assembled to the heat sink 106, the heat sink 106 is fixed on the flange 102a of the lamp housing. Therefore, the heat energy of the heat sink 106 can only be conducted to the entire lamp housing 102 through the flange 102a, but the contact area is extremely small, resulting in a low heat dissipation efficiency. [0003] China Taiwan New Patent Announcement No. M482521 discloses a car light structure, which includes a lighting unit, a cooling unit and a waterproof cover. The lighting unit includes a fixing seat, a lens and a luminous element, and th...
