Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, in an embodiment of the present invention, a motorcycle LED headlamp includes a lamp rear case 500, a lamp front cover 100 is installed on the lamp rear case 500, a lamp mechanism 300 for emitting light is installed inside the lamp rear case 500, a daytime running lamp mechanism 200 for making the headlamp more striking is installed inside the lamp rear case 500 between the lamp mechanism 300 and the lamp front cover 100, and a waterproof cover 400 for protecting the lamp mechanism 300 and the daytime running lamp mechanism 200 from water is installed inside the lamp rear case 500 of the lamp mechanism 300 away from the lamp front cover 100.

Light mechanism 300 includes heat dissipation mount pad 300C, heat dissipation mount pad 300C is installed in the one side that waterproof cover 400 is close to lamp front shroud 100, fixed mounting has the first LED chip light emitting source 300A that is used for luminously on heat dissipation mount pad 300C, be covered with on the first LED chip light emitting source 300A and be used for carrying out the lens 300B that refracts to the light that first LED chip light emitting source 300A sent, heat dissipation mount pad 300C upper end fixed mounting has the free curved surface optical reflector 300E that is used for carrying out the transmission to light, install on the heat dissipation mount pad 300C between free curved surface optical reflector 300E and the first LED chip light emitting source 300A and be used for luminously second LED chip light emitting source 300D, one side fixedly connected with heat radiation fins that first LED chip light emitting source 300A was kept away from to heat dissipation mount pad 300C.
