An LED is a solid state semiconductor device capable of converting electrical energy into visible light, which can directly convert electricity into light. The LED lamp has wide application range at present, is applied to the fields of an indicating light source of an instrument, an automobile signal lamp, a display screen, a key-ring type micro flashlight and the like, particularly the LED lamp with the lens, and has the advantages that the uniformity, the irradiation distance and the paving effect of light rays of the LED headlamp with the lens are far better than those of the LED headlamp without the lens. The LED headlamp with the lens has the characteristic of condensing light, namely, the light source is distributed uniformly, and the light is not strong in some places and is weak in some places. While the light from a lamp without a lens is diffuse and the light source is not well controlled.

Especially in the aspect of illumination problems of maintenance vehicles or construction places, in order to improve the illumination definition of the maintenance vehicles or the construction places, especially when illumination is uneven and is unclear far from a light source, the concave lens is also adopted to distribute light to the light source, but the utilization rate of the light flux of the light source is low, which means that light with a large light-emitting angle of the light source cannot be utilized, and finally the light efficiency utilization rate of the lamp is low. When the LED light source is used for floodlight illumination, the light distribution of the LED light source is generally carried out by adopting the light reflecting cup, but the light intensity of the paraxial part of the LED light source is larger, but the light of the part cannot be distributed through the light reflecting cup, so that the light distribution effect is not ideal, and the floodlight distributed by the light reflecting cup always has higher light intensity of the middle part. Therefore, how to obtain a stable lens system which is adaptive according to the ambient light illumination in a maintenance workshop or a construction site is a technical problem which needs to be solved urgently in the development of the current LED lamp.
