The focusing type head lamp is characterized by also comprising an adjustable lens component, wherein the adjustable lens component is arranged in the front shell, and comprises a front cover, a pressing ring, a convex lens cup and an O-shaped sealing ring; the convex lens cup is fixed on the front cover through the O-shaped sealing ring and the pressing ring; two or more focusing guide pins are arranged on the front cover; the focusing distance of the focusing guide pins is equal to the focal length of the convex lens cup; and the O-shaped sealing ring is sleeved on the adjustable lens component. The focusing type head lamp has the advantages that: condensation and dispersion of faculae can be steplessly adjusted between the most condensed light and the most flooded light; only one light source is used for realizing the working mode of light condensing and floodlighting, so that the structure is compact, and the volume and weight are greatly reduced; and a waterproof structure is adopted, so that the ingress protection (IP) level is not influenced.
Description
[technical field]
The utility model relates to lighting, relates to a kind of floodlight worn on head of Focusable particularly.
[background technology]
At present, existing head lamp can be divided into following three types substantially at the focusing technical elements: the function that 1, does not have light modulation focusing: can not can not switch the serviceability of optically focused, floodlight according to the size of using needs adjustment projection hot spot; 2, adopt optically focused, two groups of above light sources of floodlight: placing two groups of lamp sources and reflecting element thereof in the lamp holder the inside, one group of optically focused usefulness, another group floodlight usefulness utilizes the folding condition of console switch to switch the mode of operation of optically focused, floodlight.Its shortcoming is: two groups of light sources take up room relatively, cause that structure is big, volume heavy, and the hot spot adjustment is relatively mechanization, light modulation focusing flexibly also; 3, rotation mode mobile optical components and parts focusing: light source position is constant, and the rotary optical components and parts are controlled the gathering of hot spot, floodlight mode of operation with the distance that changes the relative light source of its focus.Though this scheme can realize electrodeless focusing, its shortcoming is: the bad sealing of structure influences light fixture IP degree of protection.The defective value of said prior art must improve.
[utility model content]
The purpose of the utility model is to above-mentioned technological deficiency a kind of focusing type head lamp to be provided, and this a kind of focusing type head lamp can be implemented in the serviceability of light modulation focusing in the same group of light source under the prerequisite that does not influence light fixture IP degree of protection.
The technical scheme of the utility model is described below: a kind of focusing type head lamp; Comprise led light source, fore shell, base, fixed support, led light source is fixed on the fore shell through base and fixed support, it is characterized in that; Also comprise an adjustable lens assembly, this adjustable lens assembly is installed in the fore shell.
According to the utility model of said structure, its characteristic is that also said adjustable lens assembly comprises protecgulum, O RunddichtringO, convex lens, cup trim ring, and convex lens cup is fixed on the protecgulum through O RunddichtringO, trim ring.
According to the utility model of said structure, its characteristic is that also said protecgulum is provided with two or more focusing lead foots.
According to the utility model of said structure, its characteristic also is, preferably is provided with three focusing lead foots on the said protecgulum.
According to the utility model of said structure, its characteristic is that also the focussing distance of said focusing lead foot equates with the focal length of convex lens cup.
According to the utility model of said structure, its characteristic also is, also is arranged with an O RunddichtringO on the said adjustable lens assembly.
According to the utility model of said structure, its beneficial effect is, can be between optically focused, floodlight electrodeless adjusting hot spot gather diffusing; Realization gathers, the mode of operation of floodlight is only used a light source, compact conformation, and volume, weight significantly reduce; Adopt waterproof construction, do not influence the IP degree of protection.

Accompanying drawing 6 is the fundamental diagram of this practical optically focused pattern.
In the drawings: 1, adjustable lens assembly; 11, protecgulum; 12, O RunddichtringO; 13, O RunddichtringO; 14, convex lens cup; 15, focusing lead foot; 16, trim ring; 2, fore shell; 3, fixed support; 4, led light source; 5, base.
[specific embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Shown in accompanying drawing 1, a kind of focusing type head lamp comprises led light source 4, fore shell 2, base 5, fixed support 3; Led light source 4 is fixed on the fore shell 2 through base 5 and fixed support 3; It is characterized in that also comprise an adjustable lens assembly 1, this adjustable lens assembly 1 is installed in the fore shell 2.
Shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4; Said adjustable lens assembly 1 comprises protecgulum 11, O RunddichtringO 12, convex lens cup 14, trim ring 16; Convex lens cup 14 is fixed on the protecgulum 11 through O RunddichtringO 12, trim ring 16, and said protecgulum 11 is provided with two or more focusing lead foots 15, preferably is provided with three focusing lead foots 15; The focussing distance of said focusing lead foot 15 equates with the focal length of convex lens cup 14, also is arranged with an O RunddichtringO 13 on the said adjustable lens assembly 1.
The adjustable lens assembly that is with O RunddichtringO 13 1 is put in the fore shell 2, be fixed to led light source 3 usefulness fixed supports 3, base 4, screw on the fore shell 2 again.During light fixture work, but, regulate the distance of convex lens cup 14, change the focal position, realize the serviceability of light modulation focusing with led light source 3 through moving the position of lens subassembly 1.
The operation principle of the utility model is following:
Shown in accompanying drawing 5, accompanying drawing 6; When adjustable lens assembly 1 is shifted the end onto in fore shell 2; Led light source 3 arrives the focal length of the distance of convex lens cup 14 less than convex lens cup 14, and the light that LED spot light 3 sends is dispersed after 14 refractions of convex lens cup, and beam diameter is maximum; Play the dipped headlights effect, be in the floodlight mode of operation; Move adjustable lens assembly 1 toward fore shell 2 foreign sides, led light source 3 enlarges to the distance of convex lens cup 14 gradually, and LED spot light 3 moves closer to the focus of convex lens cup 14; It sends light beam and after refraction, gathers gradually, and when convex lens cup 14 moved to the stroke maximum toward fore shells 2 are outer, led light source 3 was with the focus coincidence of convex lens cup 14; Light beam gathers most; Play the high beam effect, center illumination is also the highest, is in the optically focused mode of operation.The stroke maximum is that the spacing length of the focusing lead foot 15 that is provided with by protecgulum 11 is provided with, and its size equals the focal length of convex lens cup 14.Because the focusing process, moving back and forth before and after 1 of adjustable lens assembly is done, having living space on the protecgulum 11 is provided with hermetically-sealed construction, seals admittedly can O type circle 12 be installed between protecgulum 11 front shells 2, the IP degree of protection of the process influence light fixture of avoiding focusing.
Though the utility model is described with reference to the above embodiments; But those of ordinary skill in the art can recognize very clearly that fully above embodiment is used to explain the utility model; Wherein can make variations and modifications and not break away from the utility model in a broad sense; So be not as qualification to the utility model; As long as in the connotation scope of the utility model, all will fall within the protection domain that the utility model requires variation, the distortion of above-described embodiment.
