Technical Field
[0001] The utility model relates to the technical field of automobile lamps, in particular to a novel LED daytime running lamp. Background Art
[0002] Daytime running lights are special lights that turn on automatically when the car engine is started. Their function is to
[0003] In such weather conditions, driving can be better perceived and identified by other road users. According to official statistics, installing daytime running lights on vehicles can reduce 12.4% of vehicle accidents and 26.45% of the chance of death in traffic accidents. Early daytime running lights used halogen bulbs as light sources, which had the disadvantages of short service life and high power consumption. With the emergence of LED green light sources, daytime running lights mostly use LED configurations, which have the characteristics of long service life, small size, good stability, and fast response speed.
[0004] Chinese patent CN212204395 U discloses an LED daytime running light, including a lampshade, an LED module, a reflector, a lamp housing, a power cord, a drive board, a heat dissipation valve and a PCB board, wherein the reflector is fixed in the lamp housing, the PCB board is fixed on an outer side of the reflector, the LED module is fixed on the PCB board, and one end of the LED module extends into the reflector, the drive board is fixed in the lamp housing, the drive board is connected to the PCB board, the power cord and the heat dissipation valve are both fixed on the lamp housing, the power cord is connected to the drive board, and the lampshade is fixedly connected to the lamp housing. It can be seen from the accompanying drawings that the lampshade of the daytime running light is an integrated piece including a main body protruding forward and a flange extending outward, and the flange is arranged on the edges around the bottom of the main body. The internal space of the lamp can be enlarged by the arrangement of the flange, and the reflector is fixed in the lamp housing, and the top opening of the reflector is larger than the main body of the lampshade. The light provided by the LED module when working is reflected by the reflector and forms a daytime running light functional beam through the lampshade. Since light is emitted from the non-main light surfaces on the flange and the main body, a large number of light spots are present in the daytime running light functional beam. At the same time, since the lower side, left side and right side of the reflector are all large-area light surfaces that reflect light, a large number of stray lights are present around the daytime running light functional beam, which greatly affects the optical quality and use effect. In addition, the internal structure of the lamp can be seen from the front of the lampshade, and the appearance is not very beautiful. Utility Model Content
