Please, wherein lighting device of the present invention is shown totally by mark 10 referring to Fig. 1 and Fig. 2.This lighting device 10 comprises the housing 12 of dress bulb 14 in.The back side of this housing has one to be fixed to rotatable turn-knob 16 on the housing 12 in the following manner by an intervalve 18.One neck 20 is made one with housing 12, the button 22 that two manipulation lighting devices 10 are arranged on it, this neck 20 is contained on the base 24, this base can position of being held shown in Figure 1 by the user and shown in Figure 2 be placed on one be used between the lip-deep position of support housing 12 movable.Between base 24 and the housing 12 be connected and manner hereinafter describes in detail.

Can see in from Fig. 3 to Fig. 8 that the screw 28 that knob 16 1 has head 30 is tightened on the pipe 26.There is an openend 32 towards knob 16 at the center of pipe 26.The size of the opening 34 of openend 32 is made the threaded portion that can pass screw 28, but its head 30 can't pass.The main body 36 of pipe 26 is passed the hole 38 of pipe 18 and is connected with knob 16.By this structure, knob 16 can rotate relative to managing 18 with pipe 26 simultaneously.

There is screw thread the inside of pipe 26, is used for connecting with the corresponding end of thread 40 of a carrier 42.Bulb 14 is contained on second end 44 of this carrier 42.Can find out that from Fig. 3 and Fig. 4 housing 12 comprises pipeline 46 (see figure 4)s that its bottom surface is roughly straight, carrier 42 can slidably reciprocate therein.Because the bottom surface of carrier 42 is also straight, so its relative duct size 46 can only be slided and can't be rotated.Pipe 18 comprises that one can tightly be screwed into the threaded portion 48 on the housing 12 corresponding threaded portions.Reflector 50 is equipped with in the inside of housing 12, is used for reflecting the light that bulb 14 sends.

When assembling above-mentioned each parts as Fig. 3, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, thereby carrier 42 bulb 14 on it can move abreast with longitudinal axis, because pipe 18 is tightened on the housing 12, so user's rotatable knob 16 and pipe 26.Because carrier 42 can only slide in pipeline 46, thereby therefore rotation pipe 26 can force carrier 42 to slide according to the rotation direction of pipe 26 knobs 16 or slip away pipe 26.

When carrier 42 was positioned at Fig. 5 and inner terminal position shown in Figure 6, the light that bulb 19 sends was parallel with the longitudinal axis of carrier 42 after reflector 50 reflections.When carrier 42 is positioned at Fig. 7 and outermost end position shown in Figure 8, some place on the longitudinal axis of the light that bulb 14 sends through focusing on carrier 42 after reflector 50 reflection, the shape of reflector 50 also can be made and make reflection ray focus on another some place or penetrate with the longitudinal axis of carrier 42 angledly.

As depicted in figs. 1 and 2, printing opacity shield 52 is equipped with in the both sides of housing 12, and being equipped with in the space between each shield 52 and housing 12 for example can be by the flash lamp (not shown) of one of button 22 manipulation.Particularly, all shields 52 include a lip 54 that can be clamped between pipe 18 and the housing 12.This means that when pipe 18 was tightened onto on the housing 12, it was fastened to shield 52 on the housing 12 simultaneously.

Can find out that from Fig. 9 and 10 base 24 is equipped with a switch 56, its first end 58 is with a spring 60.The length of first end 58 is shorter than the centerline length of spring 60.Although switch 56 is subjected to the biasing of spring 60 usually, when shifting to the bottom 62 of base 24, switch 56 can make spring 60 compressions.Its second end 64 and ratchet 66 engagements when switch 56 is in common position.When switch 54 moved apart ratchet 66, base 24 can rotate relative to neck 20, thus thereby the angle of cut between adjustable frames 24 and neck 20 housings 12.Going back live wire 68 in the base 24 makes lighting device 10 be electrically connected with external power source.Though not shown in the present embodiment, this lighting device 10 also can comprise other parts and make bulb 14 because battery and so on is powered at the stream power supply.

Please referring to Figure 11 to 13, base 24 comprises the first and second half 70a of and the 70b that tighten together with a screw 72.One bolt part 74 and the first half 70a of with hollow shaft 76 make one.Between circle wall 78 and axle 76, some arc dimples 80 are arranged.Axle 76 inserts in the hole 82 of a conduit 84, between axle 76 and the conduit 84 spring 86 is arranged.Spring 86 also is enclosed within on the part of a protuberance 88 of the second half 70b of.Conduit 84 has 6 arc-shaped protrusions 90 on the end face of the first half 70a of, its size and shape can embed in the arc dimple 80.The pars intermedia of conduit 84 is hexagonal prismoid shape, and the notch spare 94 of its outer surface and neck 20 is fitted.The shape of notch spare 94 is made and can be prevented that conduit 84 and neck 20 from relatively rotating, thereby conduit 84 can only move relative to neck 20 along its longitudinal axis.

When thereby base 24 relative neck 20 housings 12 were pivoted, when switch 56 was threaded off with ratchet, base 24 can relatively rotate with housing 12.In this rotated, projection 90 was forced to dimple 80, thereby made conduit 84 overcome the bias of spring 86 and shift to the second half 70b of, and after base 24 and housing 12 relatively rotated certain angle, projection 90 reentered location right and embeds dimple 80.This structure helps relative base 24 roll-shells 12 and they is rested on one of some predetermined relative positions.

Should see that just example illustrates and realizes an example of the present invention above, therefore can make all corrections and/or change to this embodiment in spirit of the present invention.
