Description
Technical Field
The invention relates to automobile parts, in particular to a penetrating type rear lamp.
Background
As a new concept of designing a rear lamp of an automobile in recent years, a penetrating rear lamp of the automobile has been increasingly applied. The light signal device of the automobile is used as an important component part for the active safety of the automobile, and the back position lamp of the light signal device needs to meet the upper and lower limit range (4-17 cd) of the luminous intensity required by the mandatory regulations (GB 4785 and GB 5920) of the light signal device of the automobile under the two conditions of closing the back door (the penetrating rear lamp comprises a fixed side and a movable side) and opening the back door (the penetrating rear lamp only has the fixed side); in addition, from the viewpoint of aesthetic appearance and user perception, the on/off states of the lamp regions at the rear positions need to have the same appearance.
Because of the design of the penetrating rear lamp, the area of the movable side rear lamp is far larger than that of the fixed side rear lamp (about 5-7 times); in order to take account of the regulatory standards for car loading with light signals and to maintain the aesthetic appearance when the through rear lamp is turned on/off, the fixed side rear position lamp is usually designed to have two brightness levels. Referring to fig. 1, the penetrating rear light includes a movable side rear light 103 and two fixed side rear lights 104, a movable side rear position light 106 is disposed on the movable side rear light 103, a fixed side rear position light 107 is disposed on the fixed side rear light 104, and the luminance of the movable side rear position light 106 is the same as that of the fixed side rear position light 107; after the back door is opened, in order to ensure driving safety and meet the requirements of mandatory regulations, a back door opening signal needs to be recognized by the vehicle body controller 101, and then a control signal is output to the fixed side rear lamp 104 through the whole vehicle wiring harness 102 so as to improve the brightness level of the fixed side rear position lamp 107. The design needs to design two brightness levels for the fixed side rear position lamp, so that the power of the selected light source is high, the cost of the light source is increased, the heat dissipation design difficulty of the light source is also increased, adverse factors such as increase of heat dissipation space and specification increase of heat dissipation elements are caused, meanwhile, the whole vehicle is required to monitor the opening and closing conditions of the movable side, and the corresponding circuit control and wire harness material cost are increased.
