Abstract
The utility model discloses a light-emitting diode (LED) automobile lamp with double bulbs. The LED automobile lamp with the double bulbs comprises a lamp body and lamp holders arranged at two ends of the lamp body in sleeved mode. A slot position used for inserting an LED chip on board (COB) light source plate which fixes an LED chip directly on an aluminous base plate with a concave cup is arranged in the lamp body, and heat dissipation fins with the function of heat dissipation are arranged on the lamp body. An insulating washer is arranged on a connection part between the lamp body and each lamp holder, and good insulating properties of a positive electrode and a negative electrode of the lamp are guaranteed. The insulating washers can not only accelerate the heat dissipation, but also effectively prolong the service life of the lamp. The LED automobile lamp with the double bulbs is attractive in appearance, decent and graceful, and reliable in performance. A switchover circuit printed circuit board (PCB) with no electrode is arranged on the connection part between each lamp holder and the insulating washer, so that switchover with no electrode between the positive electrode and the negative electrode during the actual use process is guaranteed. The LED automobile lamp with the double bulbs is more convenient and reliable than an LED automobile lamp with the double bulbs with an electrode, and the LED automobile lamp with the double bulbs is novel in structure, ingenious in design, low in production cost and suitable for publication and application.
