Preferably, described thread groove is rectangular thread, and quantity is two groups; Described lead is two, comprises the first lead and the second lead, and described first lead is cylindric, and described second lead is the convex screw thread of rectangle; Described gathering sill one group, coordinates with described first lead.
Described first lead is tack machine-processed rice, with described loose collar threaded engagement, and can relatively described loose collar precession and back-out.
Described traveller is tack machine-processed rice, and quantity is two, with described retainer ring threaded engagement, and can relatively described retainer ring precession and back-out.
Described second reflector is fixed on described loose collar.
Described lens are fixed on described second reflector.
The present invention, by above structure, uses the design of bireflectance cover, effectively improves the utilization rate of light, reduce energy consumption, use wall groove guide type Zoom structure, zoom accuracy is high, compact conformation, reduce rocking of lens, gliding smoothing, avoids facula deviation, structure is simple, convenient and practical, there are larger market prospects, be applicable to wideling popularize.

Wherein: retainer ring 1, radiating fin 11, traveller 12, gathering sill 13, light source 2, lens 3, first reflector 41, second reflector 42, loose collar 5, first lead 51, second lead 52, rotating ring 6, chute 61, thread groove 62.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 2, wall groove guide type Zoom lamp, comprise retainer ring 1, light source 2, lens 3 and zoom mechanism, described light source 2 is fixed on described retainer ring 1, described zoom mechanism is installed on described retainer ring 1, described lens 3 are relative with described zoom mechanism to be fixed and is positioned at the direction of illumination of described light source 2, also comprise the first reflector 41 and the second reflector 42, described first reflector 41 is fixed on described retainer ring 1 and covers in the inner by described light source 2, and described second reflector 42 is fixed on described zoom mechanism and is covered in the inner by described lens 3.
The effect of the first reflector 41 be light-ray condensing that LED is sent together, formed and a branch ofly just beat the light beam on lens plane, so just effectively raise the light extraction efficiency of first time optical treatment.The effect of the second reflector 42 is through lens and the light beam integer again of assembling, and makes the light be up to more concentrated.
Described retainer ring 1 is cylindrical, is provided with container cavity, front opening in it, and described light source 2, lens 3, zoom mechanism, the first reflector 41 and the second reflector 42 are positioned at described container cavity.Retainer ring 1 is unique shell structure, avoids the situation that in prior art, multiple shell combination is installed, describes material cost and assembling procedure.
Described retainer ring 1 is metal material, and its bottom is provided with radiating fin 11, effectively plays the effect of heat radiation
Described lens 3 are convex lens, also can be concavees lens, or the combination of multiple convex lens or concavees lens, in order to change radiation direction, reach the object of zoom.
Described zoom mechanism comprises loose collar 5 and rotating ring 6; The inwall of described retainer ring 1 is provided with two travellers 12, and described rotating ring 6 is placed in described retainer ring 1, is provided with the chute 61 of annular, coordinates, described rotating ring 6 can be rotated by relatively described retainer ring 1 with described traveller 12, and restriction is relatively movable; Described rotating ring 6 wall is provided with two groups of thread grooves 62, and it is communicated with inside and outside wall, and described loose collar 5 is placed in described rotating ring 6, and its outer wall is provided with two groups of leads coordinated with described thread groove 62, can slide in described thread groove 62.
Described thread groove 62 is rectangular thread, and described lead comprises the first lead 51 and the second lead 52, and described first lead 51 is cylindric, and described second lead 52 is the convex screw thread of rectangle.The design of the second lead 52 convex screw thread, can improve loose collar 5 and the respective outer side edges of rotating ring 6, improve zoom accuracy.
Described retainer ring 1 inwall is provided with the gathering sill 13 that one group of fore-and-aft direction is arranged, and described first lead 51 protrudes from described rotating ring 6 and coordinates with described gathering sill 13, and described loose collar 5 can be moved forward and backward by relatively described retainer ring 1; Described second lead 52 is concordant with the outer wall of described rotating ring 6.Described second reflector 42 is fixed on described loose collar 5.Described lens 3 are fixed on described second reflector 42.
In another kind of example, described gathering sill 13 is variform two groups, and described first lead 51 and the second lead 52 protrude from described rotating ring 6 and coordinate with described gathering sill 13 simultaneously.
When rotating retainer ring 1, because described thread groove 62 coordinates with described lead, also have coordinating of described gathering sill 13 and described lead, the light source 2 that the lens 3 in described slip ring 5 are fixed in retainer ring 1 is relatively movable, to reach the object of zoom.
Described first lead 51 is tack machine-processed rice, with described loose collar 5 threaded engagement, and can the precession of relatively described loose collar 5 and back-out.
Described traveller 12 is tack machine-processed rice, and quantity is two, with described retainer ring 1 threaded engagement, and can the precession of relatively described retainer ring 1 and back-out.The design that chute 12 is removable, the installation between portable propelling ring 5 and rotating ring 6.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
