Fig. 4 more amplifies the exploded perspective view representing in the part of top by the illuminator 70 than forming the bulb type lighting device 100 of present embodiment.In reflection part 60, the position that the optical axis of the light-emitting component 71 when being fixed on radiator 50 together with illuminator 70 connects, is provided with five photoconductions and portals 65.That is the light, for example sending from the light-emitting component 71a shown in Fig. 4 arrives lens 41a by the photoconduction 65a that portals.The light transmission lens 41a that arrives afterwards lens 41a, is irradiated to outside.In addition, portal 65 end medial surface of photoconduction is the cone-shaped narrowing down towards top.Thus, can make to portal after the reflection of 65 light and see through lens 41 by photoconduction, can access the light that directive property is high.
Like this, the reflection part 60 that main part 30 possesses comprises: make the photoconduction of the light arrival lenticular unit 40 of self-emission device 71 to portal 65; Be formed on photoconduction portal 65 surrounding and reflection derive from photoconduction, portal 65 light be formed on the portal end (reflecting plate) of cone-shaped of 65 medial surface of photoconduction.
In addition, near the upper surface outer rim of reflection part 60, can chimericly be arranged on the protuberance 42(aftermentioned of the lower surface of lenticular unit 40) mode be provided with recess 63.Recess 63 and protuberance 42 are accordingly roughly by being uniformly-spaced provided with three.In addition, in the upper end of the lateral surface of reflection part 60, can chimericly be formed on the guide groove 21(aftermentioned of the medial surface of lens position adjustment component 20) mode be provided with protuberance 64.That is, protuberance 64 is formed on main part 30(, bulb type lighting device main body.More specifically, form the reflection part 60 of bulb type lighting device main body (main part 30)) side, chimeric with guide groove 21.Protuberance 64 corresponding with guide groove 21 roughly by being uniformly-spaced provided with three.
In addition, protuberance 64 can slide along guide groove 21 in guide groove 21, thus, the position of the above-below direction of lenticular unit 20 is changed.With reference to Fig. 5 and Fig. 6, be described in detail later this point.
At the upper surface of lenticular unit 40, be provided with as mentioned above five lens 41.On the other hand, at lower surface, in position that can be chimeric with the recess 63 that is arranged at reflection part 60, be provided with protuberance 42.Certainly, protuberance 42 is can above-below direction in recess 63 chimeric slidably.Protuberance 42 and recess 63 accordingly near the lower surface outer rim of lenticular unit 40 by being roughly uniformly-spaced provided with three.That is, lenticular unit 40 with in a plurality of light-emitting component 71(present embodiments, be five light-emitting components 71) a plurality of lens (being five lens 41 in present embodiment) of respectively relatively configuration and prevent the anti-rotation parts of protuberance 42(that rotate own).
Lens position adjustment component 20 is fixed on radiator 50 illuminator 70 of upper surface and the mode of reflection part 70 to surround arrange.At the medial surface of lens position adjustment component 20, be formed with the protuberance 64 chimeric guide groove 21 slidably that is arranged at reflection part 60, this guide groove 21 is chimeric and lens position adjustment component 20 is set with protuberance 64.Though guide groove 21 is not shown, at medial surface roughly by being uniformly-spaced provided with three.In addition, the medial surface in lens position adjustment component 20 is provided with the protuberance 22 for rotatably mounted lenticular unit 40.Though in Fig. 4, do not illustrate, protuberance 22 also at medial surface roughly by being uniformly-spaced provided with three.
With reference to Fig. 5, guide groove 21 and protuberance 22 are described in more detail.
Fig. 5 is the sectional view (the A-A line sectional view of Fig. 4) of lens position adjustment component 20 that forms the bulb type lighting device 100 of present embodiment.The outer rim money of lenticular unit 40 is embedded between the protuberance 22 of the medial surface that is arranged on lens position adjustment component 20 and the lower surface 24 of the cone-shaped outer rim of lens position adjustment component 20.But lenticular unit 40 can rotate freely with respect to lens position adjustment component 20 under the state being embedded between protuberance 22 and lower surface 24.That is, lenticular unit 40 is supported on slidably lens position adjustment component 20 between protuberance 22 and lower surface 24.
In addition, be formed on guide groove 21(first guide groove of the medial surface of lens position adjustment component 20) from the topmost 21a of extreme higher position, delay to decline, until the foot 21b of extreme lower position is slowly formed obliquely.Therefore, protuberance 64(first protuberance of reflection part 60) be accompanied by the rotation of lens position adjustment component 20, can between this topmost 21a and foot 21b, slide.And when sliding, protuberance 42 slides at the interior above-below direction of recess 63, do not make thus lenticular unit 40 rotate and make lenticular unit 40 mobile at above-below direction (carrying out the optical axis direction of the light of self-emission device 71).
Like this, the lenticular unit travel mechanism that the state that the bulb type lighting device 100 of present embodiment comprises maintaining light-emitting component 71 and the relativeness of lens 41 makes lenticular unit 40 move at the optical axis direction of the light penetrating from light-emitting component 71.More specifically, the lenticular unit travel mechanism that bulb type lighting device 100 possesses is configured to the rotation that is accompanied by lens position adjustment component 20, lens position adjustment component 20 moves at the optical axis direction that penetrates light from light-emitting component 71, makes thus the lenticular unit 40 that is supported on lens position parts 20 move at above-mentioned optical axis direction.
< 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 fixed on radiator 50 by screw 61.In addition, in lenticular unit 40, the protuberance 42 of lower surface that is arranged at lenticular unit 40 is chimeric with the recess 63 of upper surface that is arranged at reflection part 60, and lenticular unit 40 is with respect to reflection part 60 rotations thus.But, lens 40 from by screw 61, undertaken fixing different, by protuberance 42, at the interior above-below direction of recess 63, slide, can move by above-below direction.
Like this, lenticular unit 40, reflection part 60 and illuminator 70 configure fixing in non-rotary mode.On the other hand, in lens position adjustment component 20, lenticular unit 40 is by rotatably mounted.This refers to that lenticular unit 40 does not rotate when making 20 rotation of lens position adjustment component.
Therefore, when making lens position adjustment component 20 rotation, according to guide groove 21 position of chimeric protuberance 64 slidably, the position of lens position adjustment component 20 changes.That is, when 20 rotation of lens position adjustment component, the position of protuberance 64 is also because rotation changes, and therefore along the guide groove 21 chimeric with protuberance 64, the position of lens position adjustment component 20 changes.
Particularly, when making 20 rotation of lens position adjustment component, protuberance 64 has the interior slip of guide groove 21 of inclination, so lens position adjustment component 20 moves at above-below direction.Lenticular unit 40 can not be rotated as described above, but can move by above-below direction.So if 20 rotations of lens position adjustment component, although lenticular unit 40 does not rotate with this, the above-below direction that is rotated in that is accompanied by lens position adjustment component 20 moves, lenticular unit 40 moves at above-below direction.With reference to Fig. 6, this point is further illustrated.
The figure of the action of each parts that Fig. 6 is explanation when making lens position adjustment component 20 rotation change the distance of illuminator 70 and lenticular unit 40.Fig. 6 (a) represents that the protuberance 64 of reflection part 60 is positioned at the situation of the topmost 21a of lens position adjustment component 20, and Fig. 6 (b) represents that the protuberance 64 of reflection part 60 is positioned at the situation of position of the foot 21b of lens position adjustment component 20.
As shown in Figure 6 (a), when protuberance 64 is positioned at topmost 21a, the position of lenticular unit 40 approaches reflection part 60 most.That is, illuminator 70 is the shortest with the distance of lenticular unit 40.From this state, when making lens position adjustment component 20 for example during half-twist, protuberance 64 slides along guide groove 21, 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 pulled out from being arranged on the recess 63 of the upper surface of reflection part 60.But under this state, the part of recess 42 is also in the state chimeric with recess 63, therefore in the situation that reflection position adjustment component 20 is rotated again, lenticular unit 40 can not rotate yet.
For example, as shown in Figure 6 (a), when the distance more in short-term irradiated area expansion of illuminator 70 with lenticular unit 40.On the other hand, for example as shown in Figure 6 (a), when the distance of illuminator 70 and lenticular unit 40 is elongated, exposure intensity increases.Therefore, user can easily change illuminator 70 and the distance of lenticular unit 40 by making 20 rotations of lens position adjustment component continuously, makes the characteristics 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 change the bulb type lighting device of the characteristic of the irradiation light 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 rotation and can change the distance of illuminator 70 and lenticular unit 40.Thus, also needn't be accompanied by the position alignment of the lenticular unit that makes lenticular unit rotation and carry out, can easily to above-mentioned distance, change (that is, easily changing).In addition, by being accompanied by the knee-action of the lenticular unit 70 that the rotation of lens position adjustment component 20 carries out, above-mentioned distance changes, and therefore all can make at an arbitrary position lenticular unit 70 stop.Thus, can be more in the past than the characteristic of setting neatly the irradiation light such as irradiated area, exposure intensity.
In addition, as shown in Figure 4, etc., between illuminator 70 and lenticular unit 40, be provided with reflection part 60.Thus, can improve the directive property of the light sending from the light-emitting component 71 of illuminator 70, prevent that sent light from leaking in unexpected direction (in such as Fig. 4 left and right directions etc.).Therefore, roughly all light sending injects to outside via lenticular unit 40, thereby can improve exposure intensity.In addition, because prevent that light from for example leaking at left and right directions, so light for example can not spill between lens position adjustment component 20 and main part 30, the aesthetic property in the time of can maintaining the use of bulb type lighting device 100.In addition, because there is no spilling of light, therefore can make better light transmission lenticular unit 40.
In addition, as shown in Fig. 1, Fig. 6 etc., the lens position adjustment component 20 of adjusting the position of lenticular unit 40 is configured in the outermost of bulb type lighting device 100.That is, lens position adjustment component 20 arranges to surround the mode of the surrounding of radiator 50, among bulb type lighting device 100, becomes the parts of diameter maximum.Therefore, while changing the characteristics such as irradiated area, exposure intensity as user, during handling lenses position regulating member 20, lens position adjustment component 20 has maximum diameter, therefore easily controls.Therefore, user can make 20 rotations of lens position adjustment component by shirtsleeve operation (being ground simple to operate).Furthermore, by this operation, can make the position of lenticular unit 40 easily change, can make simply the characteristic changings such as irradiated area, exposure intensity.
In addition, in the bulb type lighting device 100 of present embodiment, the revolving force former state of lens position adjustment component 20 is as the driving force that lenticular unit 40 above-below directions are moved.Particularly, as the explanation with reference to Fig. 4, Fig. 5 etc., lenticular unit 40 is rotatably supported in lens position adjustment component 20.And, being accompanied by the movement of the above-below direction of the lens position adjustment component 20 of protuberance 64 due to the interior slip of guide groove 21, lenticular unit 40 also moves at above-below direction.
Therefore, in bulb type lighting device 100, the revolving force that does not become lens position adjustment component 20 is delivered to after other any parts, the mechanism that the driving by this other any parts is moved lens 40.Therefore, can cut down the quantity of the parts that form bulb type lighting device 100.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, so parts friction minimizing each other, the power (making the power of lens position adjustment component 20 rotations) that can be used in mobile lens parts 40 reduces.Thus, no matter be which kind of user, all can easily change the position of lenticular unit 40, change the characteristics such as irradiated area, exposure intensity.And then number of components reduces, therefore can make the occurrence frequency of loose contact etc. reduce, can improve the durability of bulb type lighting device 100.
In addition, the related bulb type lighting device 100 of present embodiment comprises that lamp holder 31(is with reference to Fig. 1 etc.), by being connected with general socket, can directly use.Therefore, such as utilizing, be arranged at the socket that roof, wall etc. are located, just can have utilized bulb type lighting device 100, needn't import new equipment or equipment.Therefore not restriction of place is set, can be used in various places.
