Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to an automobile lamp with good heat dissipation effect. Background Art

[0002] Car lights, also known as car headlights and car LED daytime running lights, are the eyes of a car. They are not only related to the appearance of a car owner, but also closely related to safe driving at night or in bad weather conditions. The use and maintenance of car lights cannot be ignored.

[0003] A Chinese patent discloses a car headlight with good heat dissipation effect (authorization announcement number CN218209370U). This patent technology is used to install the protective shell and the protective cover through a fixing plate, and is also conducive to the installation of the headlight body. By setting an air intake plate, a transmission pipe, a connecting block and a fixing pipe, it is used to cooperate with the air intake pipe and the air intake cover to convey the airflow to the inside of the protective cover, so that the inside of the protective cover can be cooled down to avoid the damage of the headlight due to excessive temperature inside the protective cover. However, dust and other particles carried by the airflow are easy to adhere to the heat dissipation fins at the rear of the headlight. By using filter cotton, the incoming airflow will be reduced and will not have a cooling effect. In the case of not using a filter layer, the heat dissipation fins are easily affected by the attachments, resulting in a reduction in the heat dissipation effect, and it is still easy to cause damage caused by overheating of the headlight. Therefore, those skilled in the art provide a car headlight with good heat dissipation effect to solve the problems raised in the above background technology. Utility Model Content

[0010] Preferably, the brush strip is made of soft plastic material, which causes less damage to the heat dissipation fins.

[0011] Compared with the prior art, the utility model provides a car lamp with good heat dissipation effect, which has the following beneficial effects:
