Electronic self-control rear fog lamps for automobiles

Abstract

The invention discloses an electronic automatic control rear fog lamp for an automobile. The electronic automatic control rear fog lamp comprises a humidity sensor (1), an optical sensor (2), a three-terminal regulator (33), an MCU single-chip microcomputer (4), a first power electronic switch (5), a second power electronic switch (6), a condensation LED array (7) and a semiconductor laser array (8). By the adoption of the electronic automatic control rear fog lamp, the humidity is detected, the fog concentration is judged, the fog light transmission is detected after certain humidity is reached, the fog lamp is turned on after the light transmission descends to a certain degree, the brightness of the fog lamp can be adjusted according to the fog concentration, an intermittent light emitting manner is adopted by the fog lamp, the brightness can be adjusted, it is guaranteed that a rear driver can see a front vehicle clearly, meanwhile, strong light stimulation to the rear driver is avoided, and by the adoption of the condensation LED array (7) and the semiconductor laser array (8), efficiency is high, and energy consumption is low.

Description

technical field [0001] The invention relates to the field of electronic fog lamps, in particular to an electronic self-controlled rear fog lamp for automobiles. Background technique [0002] Dense fog weather often leads to the closure of expressways, and a large number of traffic accidents will also occur on ordinary roads due to dense fog, which brings a lot of inconvenience to people's travel. In dense fog weather, driving a motor vehicle usually requires the use of fog lights to remind surrounding vehicles and pedestrians, so as to reduce the occurrence of traffic accidents. The motor vehicle fog lamps of the prior art usually adopt the astigmatism yellow lamps formed by light bulbs, which are difficult to be found by vehicles behind in foggy days, and easily cause rear-end collision accidents. Moreover, the bulb-type rear fog lights are adopted, and the general power is about 15W, which has low efficiency and high energy consumption. Contents of the invention [000...
