The area of the central light emitting region 43 is larger than the area of the peripheral light emitting region 44, specifically, the circular diameter d of the central light emitting region 43 is 25mm, and the annular radial direction w of the peripheral light emitting region 44 is 5 mm.
The central light-emitting area 43 and the peripheral light-emitting area 44 can emit light independently, that is, the lamp has the following four light-emitting states: firstly, the central light emitting region 43 emits light, and the peripheral light emitting regions 44 do not emit light; the central light emitting area 43 does not emit light, and the peripheral light emitting area 44 emits light; the central light-emitting area 43 and the peripheral light-emitting areas 44 emit light; central light-emitting zone 43 and peripheral light-emitting zone 44 do not emit lightLight rays.
