<effect>
Then, suitably with reference to Fig. 4～Fig. 6, the effect of bulb type lighting device 100 is described.
As shown in chain-dotted line in Fig. 4, reflection part 60 and illuminator 70 are fixing by screw 61In radiator 50. In addition, in lenticular unit 40, be arranged at the lower surface of lenticular unit 40Protuberance 42 chimeric with the recess 63 of upper surface that is arranged at reflection part 60, lens section thusPart 40 does not rotate with respect to reflection part 60. But, lens 40 with undertaken by screw 61Fixing difference, slide at the interior above-below direction of recess 63 by protuberance 42, can above-below directionMobile.
Like this, lenticular unit 40, reflection part 60 and illuminator 70 are joined in non-rotary modePut fixing. On the other hand, in lens position adjustment component 20, lenticular unit 40 is by rotatablySupporting. This refers to that lenticular unit 40 does not rotate in the time that lens position adjustment component 20 is rotated.
Therefore, in the time that lens position adjustment component 20 is rotated, according to guide groove 21 slidablyThe position of the chimeric protuberance 64 in ground, the position of lens position adjustment component 20 changes. ,In the time that lens position adjustment component 20 is rotated, the position of protuberance 64 is not also because rotation becomesChange, therefore along the guide groove 21 chimeric with protuberance 64, the position of lens position adjustment component 20Change.
Particularly, in the time that lens position adjustment component 20 is rotated, protuberance 64 inclines havingThe oblique interior slip of guide groove 21, therefore lens position adjustment component 20 moves at above-below direction. ThoroughlyMirror element 40 can not be rotated as described above, but can move by above-below direction. So,If lens position adjustment component 20 is rotated, although lenticular unit 40 is not with this rotation, companionAlong with the above-below direction that is rotated in of lens position adjustment component 20 moves, lenticular unit 40 is upperLower direction moves. With reference to Fig. 6, this point is further illustrated.
Fig. 6 be explanation by make lens position adjustment component 20 rotation change illuminator 70 withThe figure of the action of the each parts when distance of lenticular unit 40. Fig. 6 (a) represents reflection part60 protuberance 64 is positioned at the situation of the topmost 21a of lens position adjustment component 20, Fig. 6 (b)Represent that the protuberance 64 of reflection part 60 is positioned at the foot 21b of lens position adjustment component 20The situation of position.
As shown in Figure 6 (a), when protuberance 64 is positioned at topmost 21a, the position of lenticular unit 40Put and approach reflection part 60 most. , illuminator 70 is the shortest with the distance of lenticular unit 40. FromThis state, when making lens position adjustment component 20 for example when half-twist, protuberance 64 is along leadingGroove 21 slides, and the position upward direction of lens position adjustment component 20 moves (with reference to Fig. 6 (b)).Now, the major part of protuberance 42 that is arranged at the lower surface of lenticular unit 40 is from being arranged on reflectionThe recess 63 of the upper surface of parts 60 is pulled out. But, under this state, the office of recess 42Portion, also in the state chimeric with recess 63, therefore makes reflection position adjustment component 20 againIn the situation of rotation, lenticular unit 40 also can not rotate.
For example, as shown in Figure 6 (a), when illuminator 70 shorter with the distance of lenticular unit 40Time irradiated area expand. On the other hand, for example as shown in Figure 6 (a), when illuminator 70 is with saturatingWhen the distance of mirror element 40 is elongated, exposure intensity increases. Therefore, user can be by makingMirror position regulating member 20 rotates, and makes illuminator 70 easily continuous with the distance of lenticular unit 40Ground changes, and makes the characteristic such as irradiated area, exposure intensity become the value of expectation.
<effect>
According to bulb type lighting device 100 described above, can provide arbitrarily and easily changeThe bulb type lighting device of the characteristic of the light irradiation such as irradiated area, exposure intensity.
Particularly in the bulb type lighting device 100 of present embodiment unlike the prior art,Do not make lenticular unit 40 rotate and can change the distance of illuminator 70 and lenticular unit 40. ByThis, also needn't be accompanied by the position alignment of the lenticular unit that makes lenticular unit rotation and carry out,Can easily change (, easily changing) to above-mentioned distance. In addition, by being accompanied byThe knee-action of the lenticular unit 70 that the rotation of mirror position regulating member 20 is carried out, above-mentioned distanceChange, therefore all can make at an arbitrary position lenticular unit 70 stop. Thus, can be than in the pastSet neatly the characteristic of the light irradiation such as irradiated area, exposure intensity.
In addition, as shown in Figure 4, etc., between illuminator 70 and lenticular unit 40, be provided with anti-Penetrate parts 60. Thus, can improve the finger of the light sending from the light-emitting component 71 of illuminator 70Tropism, prevents that sent light from such as, letting out in unexpected direction (left and right directions etc. in Fig. 4)Leak. Therefore, roughly all light sending injects to outside via lenticular unit 40, therebyCan improve exposure intensity. In addition, because prevent that light from for example leaking at left and right directions, therefore lightFor example can between lens position adjustment component 20 and main part 30, not spill, can maintain lampThe aesthetic property when use of alveolitoid lighting device 100. In addition, because there is no spilling of light, because ofThis can make better light transmission lenticular unit 40.
In addition, as shown in Fig. 1, Fig. 6 etc., adjust the lens position of the position of lenticular unit 40Adjustment component 20 is configured in the outermost of bulb type lighting device 100. , lens position adjustmentParts 20 arrange in the mode of the surrounding of encirclement radiator 50, at bulb type lighting device 100Among, become the parts of diameter maximum. Therefore, when user changes irradiated area, irradiates by forceWhen the characteristics such as degree, when handling lenses position regulating member 20, lens position adjustment component 20 toolsThere is maximum diameter, therefore easily control. Therefore, user can be by shirtsleeve operation (Ground simple to operate) lens position adjustment component 20 is rotated. Furthermore, by this behaviourDo, can make the position of lenticular unit 40 easily change, can make simply irradiated area, photographPenetrate the characteristic changings such as intensity.
In addition, in the bulb type lighting device 100 of present embodiment, lens position adjustment partThe revolving force former state of part 20 is as the driving force that lenticular unit 40 above-below directions are moved. Specifically, as the explanation with reference to Fig. 4, Fig. 5 etc., lenticular unit 40 is rotatably supported in lensPosition regulating member 20. And, be accompanied by the lens of protuberance 64 due to the interior slip of guide groove 21The movement of the above-below direction of position regulating member 20, lenticular unit 40 also moves at above-below direction.
Therefore,, in bulb type lighting device 100, do not become lens position adjustment component 20Revolving force be delivered to after other any parts, make by the driving of this other any partsThe mechanism that lens 40 move. Therefore, can cut down the parts that form bulb type lighting device 100Quantity. Further, can be with characteristics such as simple structural change irradiated area, exposure intensities.
Further, not via other any parts, just can make lenticular unit 40 move, because ofThe friction each other of these parts reduces, and the power that can be used in mobile lens parts 40 (makes lens positionPut the power that adjustment component 20 is rotated) reduce. Thus, no matter be which kind of user, all can holdChange places and change the position of lenticular unit 40, change the characteristics such as irradiated area, exposure intensity. And then,Number of components reduces, and therefore can make the occurrence frequency of loose contact etc. reduce, and can improve lampThe durability of alveolitoid lighting device 100.
In addition, the related bulb type lighting device 100 of present embodiment comprises lamp holder 31(ginsengAccording to Fig. 1 etc.), by being connected with general socket, can directly use. Therefore, for example utilizeBe arranged at the socket that roof, wall etc. are located, just can have utilized bulb type lighting device 100, noMust import new equipment or equipment.
