Chinese patent document (the day for announcing: on December 2nd, 2009, notification number: CN201354939Y) disclose a kind of tunable optical flashlight, a kind of stack shell that comprises is provided, battery, board box, illuminating lamp, lens; Also comprise movable roll adjustment system, movable roll adjustment system is positioned at stack shell, the tunable optical flashlight between protheca and the pedestal.But above-mentioned tunable optical flashlight structure is complicated, uses inconvenient.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, light modulation flashlight easy to use in order to solve flashlight light modulation problem.
The utility model solves the technical scheme that its technical problem adopted: a kind of light modulation flashlight; Comprise cylindrical barrel body, lamp holder and tail-hood; Be slidingly connected between described lamp holder and the cylindrical barrel body, the front end set inside of described cylindrical barrel body has radiating seat, and the set inside of radiating seat has LED; The diameter of described cylindrical barrel body leading section is less than the diameter of main part; Described lamp holder comprises skull, be arranged on the head-shield of skull front end and be arranged on the inner lens of head-shield, on the internal circumference of described skull convexity is set, and the diameter of described convexity is less than the internal diameter of the skull diameter greater than the cylindrical barrel body leading section; Described convexity and cylindrical barrel body leading section are slidingly matched, and are provided with an adjustable cavity between the rear end face of described head-shield and the front end face of radiating seat.Be slidingly connected between lamp holder and the cylindrical barrel body, be provided with adjustable cavity between the rear end face of head-shield and the front end face of radiating seat, when lamp holder when cylindrical barrel body endwisely slips; The head-shield that lamp holder drives with its fixed connection slides; Cavity size on head-shield and the cylindrical barrel body between the radiating seat of front end correspondingly changes, and the distance between lens and the LED changes, and has realized the light modulation purpose of flashlight astigmatism or optically focused; The needs under the different situations have been satisfied; Compare with other light modulation flashlights in the prior art, this is simple in structure, easy to operate.
As preferably, the adjustable cavity axial length between the rear end face of described head-shield and the front end face of radiating seat is 0 to 10 millimeter.This structure is to design according to the sliding distance of skull convexity on the cylindrical barrel body leading section; When skull slides to the rear end of cylindrical barrel body; Distance between the rear end face of head-shield and the front end face of radiating seat just diminishes; When skull slided to the front end of cylindrical barrel body, it is big that the distance between the rear end face of head-shield and the front end face of radiating seat just becomes, and realized the purpose of flashlight light modulation through the adjustment of said structure.
As preferably; Described radiating seat excircle is provided with boss; The diameter of described boss is greater than the diameter of the cylindrical barrel body leading section internal diameter less than skull; The rear end face of described boss cooperates with the front end face of cylindrical barrel body, constitutes one section ring-type variable cavity between the shaft shoulder of boss and cylindrical barrel body leading section, and the greatest axial length of described ring-type variable cavity is 10 millimeters.On radiating seat, adopt boss structure, this structure has guaranteed that the convexity on the skull can be free to slide in the cavity of cylindrical barrel body leading section, can not throw off with cylindrical barrel body, adopts this structure simultaneously, and is easy for installation.The size of this cavity is that as daily instrument, the light of flashlight can only be adjusted in certain scope according to the decision of the scope of flashlight light modulation.
As preferably, the cooperation place of described skull and cylindrical barrel body is provided with sealing device.Adopt sealing device to help waterproof,, also can not make the internal components water inlet, influence the function of use of flashlight in case run into the rainy day or be immersed in water.
The beneficial effect of friendship that has of the utility model really is: adopt lamp holder and cylindrical barrel body sliding connection structure; Skull drives head-shield and lens endwisely slip along cylindrical barrel body together; Adjustable cavity between lens and the LED correspondingly changes; Realized light modulation purpose to flashlight astigmatism or optically focused, simple in structure, easy to operate.
