In order to achieve this, the radiating pipe 4 should have good thermal conductivity, and a metal having good thermal conductivity, such as copper, should be preferably selected when selecting the material for manufacturing the radiating pipe 4. Meanwhile, in order to prevent the heat dissipation pipe 4 and the high beam 11 and the low beam 12 from moving relative to each other due to bumping during the driving of the automobile, the heat dissipation effect is deteriorated. Therefore, the connection of the heat dissipating pipe 4 to the high beam 11 and the low beam 12 should be preferably a welded connection, and other fixed connections such as a screw connection, because the working environment temperature of the whole part is high and the screw is easily damaged in the application of the lamp, are not preferable.
