One switch 44 is positioned at the upside of handle 40, and user's thumb is easier to be touched, to open and to close light source 32 '.Can select one or three slips (three position slide) switch two light sources can be set like that, make in primary importance to have only a light source to be in the closed circuit,, have two light sources to be in the closed circuit in the second place as switch 44.The 3rd position is the position of a pass (interruption).
From side view, be the view of Fig. 1, the front surface 48 of front lamp cover 26 is shape for lugs.This curve form of lampshade 26 has increased the intensity of lamp housing 20 significantly, also the light from light source 32 ' more can be spread.It should be noted that the curvature on surface 48 is arches, the radius of curvature is quite big, that is, more much bigger than the length overall of body.The curve form of lampshade 26 also provides very beautiful exhilarating outward appearance for lighting device 10.
Fig. 7 and 8 shows in detail hinge connector 22.Body 12 comprises that one crosses over the axle 50 of its relative both sides, and provides the installation shaft of a suitable rigidity to connect thereon for lamp housing 20.Lamp housing 20 is provided with a pair of hoop 52 of axle on 50 that be enclosed within, as shown in Figure 8, and by some screws 54 be clamped in axle 50 around.The clamping degree of the hoop 52 on axle 50 can change by adjustment screw 54.In addition, by being hoop 52 and axle 50 formulation suitable dimensions, the friction of quite identical size when hoop 52 can produce with assembling lighting device 10 on production line or assembly line with axle 50.Preferably, lamp housing 20 can forward any selected position in about 270 ° of radians to.So just lighting device 10 can be stood upright on its base 14, and lamp housing 20 can leave the position of body 12 to any selection.
Because the whole periphery of lampshade 24 is translucent, when lamp housing 20 leaves body 12 when upright vertically upward, lamp housing 20 is with 360 ° radian disperse light roughly, the form of vinegar ceraceous candle.Also have, lamp housing 20 can meet at right angles with the length of body 12, makes this lamp can be used as a desk lamp or similar lamp.Be noted that, in assembling process, screw 54 to be adjusted to and make the friction grip power the best that is enclosed within the hoop 52 on the axle 50, thereby can quite easily rotate lamp housing 20, the position of lamp housing 20 with respect to body 12 can also be remained on any selected arc position that turns to relative to body 12.
If desired, lighting device 10 needn't adopt whole form described herein, although be considered to favourable owing to above-mentioned reason has the form shown in the accompanying drawing.It is contemplated that the manufacturing of lighting device 10 is quite simple, thus quite cheap, and also not only firm, can also be applied to multiple different purposes, make lighting device 10 have multifunctionality.
Although more preferably adopt the rubbing device of hoop 52 and axle 50 forms, the engagement in rotation device such as ratch mechanism that can calibration rotates also can use.
Fig. 9 illustrates lamp housing 26 with the lifting position with respect to body 12.In this position, can see the side 12A of body 12, and notice the existence of rectangular mirror 12B.
When lamp housing 20 leans on mutually with side 12A, speculum 12B guarantees to leave body side 12A by whole visible spectrums reflections of the light of the 32 ' generation of the light source in the lamp housing 20, avoid most visible light to be absorbed, use up to guarantee making of largest portion by body side 12A.
Speculum 12B can be the sheet material of gloss very, silver-plated, white or other high reflective sheet, and this material can be the plastics of metallo-plastic or metallizing.
Preferably, sheet material is laid between the left and right sides two halves of body 12, or adheres to side 12A, or connects thereon.The citation form of speculum 12B is that a white plastic is pasted.
Another feature of lamp housing 26 is, when lamp housing 20 during near body side 12A the one side 26A (seeing Fig. 7 and 9) of directed outward constitute by a frosted or translucent lens, pure or transparent lens constitutes and opposite side 26B is by one.Guaranteed like this that when the light source in the lamp housing 20 32 ' is opened speculum 12B is because the properties of transparency of side 26B is accepted a large amount of light, this light will return after reflection and pass through side 26B, thereby cause more effectively propagating through the light of side 26A.If lighting device 10 is used for reading, that is particularly advantageous.Although can not express frosted and pure surface layer among the figure, as can see from Figure 7, has different hatchings in 26A and the cross section shown in the 26B.
Figure 10 to 21 illustrates the lighting device of a hand lamp 102 forms, and this hand lamp 102 has one and total is the lens subassembly of rectangle or lamp housing 104, and it is connected in rotationally by a pivot assembly 108 and totally is the body 106 of rectangle.The hand lamp 102 of Figure 10 shows the lamp housing 104 at expanded position, and Figure 12,13 and 15 shows at the lamp housing with respect to the retrieving position of body 106.
In the view of Figure 10, body 106 has the overall structure with a front surface 110, a rear surface 112 and left and right side 114 and 116 of rectangle that is.Pivot assembly 108 forms from the extension 118 of body 106 and the about 45 ° of inclinations of vertical line and 120 by two, but also can adopt 15 ° to 60 ° angular range.
Figure 10 illustrates the lamp housing 104 in vertical direction, such direction is under the help of footing 122, and the center of gravity of guaranteeing lamp housing 104 is between the terminal backwards 122D of the terminal forward 122A of footing 122 and base 122D.This causes the structure of hand lamp 102 shown in Figure 10 and 11 to be in a settling position, although the center of gravity of lamp housing 104 has departed from the position through the longitudinal axis of body 106 centers of gravity.
And when lamp housing 104 forwarded as shown in figure 16 farthest turned position to, its center of gravity was in fact very near the center of gravity of body 106.
The quality of all dry cells and body 106 has been guaranteed the overturning phenomenon can not occur greater than the quality of lamp housing 104 like this.
One rotatable handle 123 is arranged between half 106A and second half 106B of body 106, can turn to it from the position of an adjacent side face 112 always and contact with lamp housing 104.Thereby, the determining positions of lamp housing 104 rotational limitation of handle 123.
The terminal forward 122A of pivot assembly 108 and footing 122 cooperates, make when lamp housing 104 forwards its as shown in figure 16 farthest rotatable position to, hand lamp 102 can be placed on the table top or other horizontal surface (total represents with axis 130), form one body 106 remained on the tripod layout of stabilising direction, and lamp housing 104 is handed at an angle (surface that axis 130 is represented a basic horizontal) on axis 130.
In addition, handle 123 is cooperated with as shown in figure 18 terminal backwards 122D, and body 106 is shelved on the surface with imaginary line 130 expressions with the edge 123A of terminal 122D and handle 123 backwards.Because body 106 roughly holds four D cell type batteries, body 106 in the hand lamp 102 will have enough quality, and will be much bigger around the moment that same point produced with the upper body part that comprises pivot assembly 108 around the torque ratio lamp housing 104 that the 123A of handle 123 produces.This structure causes very flexibly and variable layout, and the user adopts this structure can obtain the stability of certain degree.
In withdrawal direction shown in Figure 12, the lamp housing 104 of hand lamp 102 is near body 106.As can be seen from Figure 14, an access panel 128 is arranged on the front surface 110 of body 106, makes the user of hand lamp 102 can touch the battery chamber, to change or to install dry cell.The feature of hand lamp 102 is, access panel 128 is made by high reflecting material, such as the material of silver-plated polymeric material, reflective metals, plastic-metal or lacquer white etc.Guaranteed to have lamp housing 104 as the retrieving position of Figure 12 like this, and light source is when being opened, after the wide part of the direction emission of body 106 is by plate 128 reflections, returns and pass lamp housing 104 backs and penetrate by what lamp housing 102 produced when hand lamp 102.Guaranteed like this regaining the orientation, hand lamp 102 can stand upright on the estrade, and produces and be enough to read or light that other is movable.
Another feature of hand lamp 102 is, when lamp housing 104 forwarded the position at the vertical or center of mistake as shown in figure 16 to, the 360 ° circumference of lamp housing 104 around its longitudinal axis were luminous, and its mode of action is similar to candle.
As shown in figure 15, the cross section of hand lamp 102 shows pivot assembly 108 and comprises that one utilizes friction screw 108B to be fixed in the pivot anchor clamps 108A of body 106.The moment of torsion that acts on friction screw 108B has determined pivot anchor clamps 108A to put on the friction level of sleeve pipe or axle 108C, this sleeve pipe or axle 108C and lens mount 126 to dwindle part 126A integrally formed or be fixed thereon.Pivot anchor clamps 108A makes lens mount 126 and lamp housing 104 can be positioned on any position between the rotation limit position of lens mount 126, and lens mount 126 is remained on this position and without any need for the help in the external world.Pivot anchor clamps 108A is by just accomplishing these with sleeve pipe or the axle frictional force that 108C produced.
Between half 106A of body and 106B, there are enough spaces to hold four D type dry cells 139, comprise a printed substrate 141 at the top of body 106, and have the switch near the upper surface the pivot assembly 108 124 that suitable circuit and control piece lead to body 106.
Figure 19 and 20 shows supplementary features, and it makes lamp housing 104 that very high efficient be arranged, and for the user very big range of choice is arranged.
But the access panel 128 that no longer needs to be provided with reflected white-light once rotation reflecting plate 128A if you are using.That is, plate 128 will not need reflected white-light.
Rotating reflecting plate 128A is made by a sheet material that has surperficial 128B that can the reflect visible light spectrum.Reflecting material can be at present available such as polishing, silver-plated, what apply maybe can be any in the reflecting material of white sheet material of required metal or plastics.
Another side 128C can have same reflecting properties, but this is inadvisable.
Wing 128D and 128E are propped up in the installation that reflecting plate 128A has two right-angle bendings or is connected in surperficial 128B.Prop up wing 128D and 128E and have coaxial aperture, pivot assembly 108 passes wherein.If desired, this mounting structure can rotate reflecting plate 128A and lamp housing 104 or in after this rotation whenever simultaneously.
Therefore, when lamp housing 104 forwarded its as shown in figure 20 limit position of rotation to, reflecting plate 128A was rotatable, thereby near lamp housing, guaranteed that like this lamp housing 104 utmost points effectively with respect to body 106 and the emission of direction backwards light down.When lamp housing 104 and speculum 128 all were in retrieving position, similar effects can appear.
Figure 21 one is similar to the section of Figure 15, wherein similarly parts with identical numbering.Difference between Figure 15 and 21 embodiment is that the light source 32 ' (being a fluorescent lamp) of Figure 15 is substituted by a tube lens 32 and a light emitting diode (LED) 34 '.If desired, another light emitting diode 34 of representing with imaginary line among a Figure 21 can be set at the other end of tube lens 32 ".This structure is similar to earlier in respect of figures 1 and 4 descriptions of being done.Another selection is, the light source that is adopted can be a diameter about 3 to 6 millimeters cold-cathode fluorescence lamp.
Be appreciated that the present invention open at this and that limit may also extend into all other combinations of two or more each feature above-mentioned or that obviously obtain from text or accompanying drawing.All these are different has constituted others of the present invention.
Without departing from the present invention, the above embodiment of the present invention and its variation are conspicuous to those skilled in the art.
