The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

As depicted in figs. 1 and 2, the portable illumination device of a kind of improvement that the utility model discloses comprises shell 11, battery cover 12, battery 13, control system 14, PCB wiring board 15, first hand switch 16, LED lamp 17, light-sensitive element 18, translucent cover 19, pyroelectric infrared sensor 20 and Fresnel Lenses 21; Shell 11 and battery cover 12 fasten the ccontaining cavity that forms an end opening, and translucent cover 19 is installed in the opening part (being that translucent cover 19 is connected with shell 11, battery cover 12 respectively) of ccontaining cavity.PCB wiring board 15 is arranged in the ccontaining cavity.

First hand switch 16, battery 13, control system 14, LED lamp 17, light-sensitive element 18, pyroelectric infrared sensor 20 and Fresnel Lenses 21 are installed on the PCB wiring board 15.LED lamp 17 and light-sensitive element 18 are positioned at PCB wiring board 15 towards a side (be that LED lamp 17 is luminous through transparency cover 19, light-sensitive element 18 sees through transparency cover 19 induction external environment brightness) of transparency cover 19.

Battery 13 is positioned at PCB wiring board 15 towards a side (being that battery 13 is between battery cover 12 and PCB wiring board 15) of battery cover 12.Shell 11 is provided with through hole 111, and Fresnel Lenses 21 is socketed in outside the pyroelectric infrared sensor 20.Fresnel Lenses 21 can guarantee that not only the result of use of pyroelectric infrared sensor 20 is better, and its cost is lower.Fresnel Lenses 21 is located in the through hole 111 of shell 11.
