Embodiment
The lighting device 1 of the 1st execution mode of the present invention is described referring to figs. 1 through Fig. 9.Lighting device 1 shown in Figure 1 is arranged on the ceiling 101 of cab 100 of elevator.After, the explanation in each execution mode for convenience before the door side of cab 100 is defined as, after the inside side is defined as, is seen from cab and is defined the right side and a left side.
As shown in Figure 3, each lighting unit 10 has cold-cathode fluorescence lamp 11, converter 12, pedestal 13 and covers 14.Cold-cathode fluorescence lamp 11 has in the way of glass tube 110 approximate right angle ground crooked 2 times and be bent to the bend 111 of rectangle.Therefore, make the end 112 of glass tube 110 all in a side.In cold-cathode fluorescence lamp 11, become the glass tube 110 of the straight line portion in the interval between bend 111 and the end 112, separate the certain intervals that in the brightness of light diffusing sheet 3, does not produce inequality, and linearity extends in parallel.
The electrode of cold-cathode fluorescence lamp is sealed in the end 112 of glass tube 110.As shown in Figure 4, end 112 supports piece 113 to cover by insulating properties and the good rubber system end of thermal endurance.Support the inside of piece 113 to be connected from the lead that electrode extends by the end with converter 12.And as shown in Figure 5, cold-cathode fluorescence lamp 11 is equipped with and supports piece 114 in the middle of having stable on heating rubber system on the position near the bend 111 of glass tube 110.The end supports that piece 113 and the middle piece 114 of supporting are examples that are used to support the elastic supporting member of cold-cathode fluorescence lamp 11, as long as can cover glass pipe 110 avoid vibration or impact, be not limited to rubber system.
As shown in Figure 3 and Figure 4, converter 12 is circuit substrates that cold-cathode fluorescence lamp is lit a lamp, and is configured in inboard that cold-cathode fluorescence lamp 11 surrounded, near on the position of end 112.Pedestal 13 keeps cold-cathode fluorescence lamp 11 and converter 12.As shown in Figure 3, cold-cathode fluorescence lamp 11 is along 3 limit configurations of the outer peripheral edges of pedestal 13.The mounting end that is used for that pedestal 13 has is as shown in Figure 4 supported the support pin 131 of piece 113 and the installation portion 132 that is used to install middle support piece 114 as shown in Figure 5.
As shown in Figure 4, pedestal 13 has 4 junction surfaces 133 that are used to install converter 12 on the position by the inboard of cold-cathode fluorescence lamp 11 clampings, close support pin 131.Have hole 134a by 1 junction surface 133 in 2 junction surfaces 133 supporting pin 131 clampings, and spiral has been inserted through the screw in the hole that is arranged on converter 12 substrate bights.Remaining 3 junction surface 133 has the chimeric protuberance 134b in hole in bight with the substrate that is arranged on converter 12 respectively.The pedestal 13 that disposes the scope of converter 12 caves in to the direction of leaving from converter 12.The location of the circuit substrate of converter 12 is supported at junction surface 133.
Fixed part 137 is to have hole minor diameter 137a and large-diameter portion 137b, so-called snowman's shape.The size of minor diameter 137a is the degree of hooking the head of the bolt 15 that is used for fixing on main body 2, and large-diameter portion 137b is the size that the head of bolt 15 passes through.
The direction that makes minor diameter 137a is an equidirectional.Therefore, when taking off lighting unit 10, become flexible main body 2 fixing bolts 15 are moved from minor diameter 137a lighting unit 10 to large-diameter portion, can take off simply thus.Fixed part 137 has the rib that extends to the opposition side that disposes the cold-cathode fluorescence lamp side along the shape in hole.In addition, fixed part 137 also can use bolt fastened tools in addition to fix.The shape of the fixed part 137 of this moment is made as and cooperates this fastened tools.
And cover 14 has rib 143,144, projection 145 and inserting hole 146.As shown in Figure 4 and Figure 5, rib 143,144 is arranged on the end and supports on piece 113 and the middle inner surface of supporting piece 114 corresponding covers 14, and to the direction of glass tube 110 crosscuts of cold-cathode fluorescence lamp 11 is extended.By making up pedestal 13 and cover 14 as shown in Figure 4, the end supports piece 113 to be sandwiched between support pin 131 and the rib 143.By making up pedestal 13 and cover 14 as shown in Figure 5, middle support piece 114 is clamped between installation portion 132 and the rib 144 as shown in Figure 9.
As Fig. 3 and shown in Figure 6, inserting hole 146 preferably is arranged on the axle identical with the center of minor diameter 137a corresponding to the fixed part 137 that is arranged on the pedestal 13.Inserting hole 146 gets final product for size and the shape that the instrument that is installed in the fastened tools on the fixed part 137 or operates this fastened tools can insert degree.
The as above lighting unit 10 of Gou Chenging as shown in Figure 1, constitute the bend 111 sides a pair of face-off configuration group G1 of linearity configuration relative to each other that makes cold-cathode fluorescence lamp 11, and the configuration group G1 that will stand facing each other is arranged as a plurality of parallel states arranged side by side.The straight line portion of the cold-cathode fluorescence lamp 11 of each lighting unit 10 each other and the straight line portion of the cold-cathode fluorescence lamp 11 of the lighting unit 10 of adjacent face-off configuration group G1 is configured to be parallel to each other and uniformly-spaced.The bend 111 of the lighting unit 10 of identical face-off configuration group G1 position is each other closed and is, and is narrower a little than the straight line portion width each other of each cold-cathode fluorescence lamp 11.
When disposing lighting unit 10 as described above, in lighting device 1, have the bend 111 of cold-cathode fluorescence lamp 11 each other at the lighting unit 10 of identical face-off configuration group G1, so the light diffusing sheet 3 of correspondence position can access enough light quantities.Therefore, on the light-emitting area 3a of the light diffusing sheet 3 of lighting unit 10 opposition sides, in brightness, be difficult to produce uneven.
Yet, be not limited to hot-cathode fluorescent lamp, even cold-cathode fluorescence lamp also needs the ignition device of one on each lamp for it is lit a lamp.In Japanese kokai publication hei 9-147802 communique, ignition device is configured in the back side of speculum with respect to the cold-cathode fluorescence lamp of linearity.So the lighting device of configuration cold-cathode fluorescence lamp and ignition device is big with respect to the volume change of projecting direction device integral body.
And, when using the linearity cold-cathode fluorescence lamp, handle for convenience, making cold-cathode fluorescence lamp all is certain length.In order to obtain necessary enough light-emitting areas,, and use many cold-cathode fluorescence lamps side by side as lighting device at projection side configuration light diffusing sheet.When parallel use cold-cathode fluorescence lamp arranged side by side, make the less light-emitting area of luminance nonuniformity by making adjacent cold-cathode fluorescence lamp distance each other approaching, can simulating.
But with the linearity cold-cathode fluorescence lamp during along the same line configured in series, each electrode is in the configuration side by side each other of adjacent cold-cathode fluorescence lamp.In lighting device, in the time will making whole face luminous equably,, therefore become darker, and on light diffusing sheet, produce luminance nonuniformity than other parts because this part brightness of configured electrodes dies down certainly.Because the brightness disproportionation on the light-emitting area of light diffusing sheet is not preferred in design, so need carry out following research, cover and block and avoid from light-emitting area by frame or edge strip are set in this part, make it not obvious thus.
And, in order to obtain homogeneous light emitting area, consider with light diffusing sheet away from cold-cathode fluorescence lamp the uneven position that disappears in brightness as light source.But, when with light source and light diffusing sheet away from the time, on the direction of projection, need the degree of depth, it is big that the volume of lighting device becomes.
On the other hand, the lighting unit of the 1st execution mode according to the present invention, have pars intermedia turned back at least once and the end all at the cold-cathode fluorescence lamp of a side.And converters is in inboard that cold-cathode fluorescence lamp surrounded.Therefore, in that this lighting unit is disposed under a plurality of situations side by side as light source, can be configured in the non-luminous each other part of adjacent lighting unit not arranged side by side.Therefore, have in the lighting device of light diffusing sheet, on light-emitting area, be difficult to produce brightness disproportionation by this lighting unit is packed into.By using a plurality of lighting units, can make the area light diffusing sheet bigger luminous equably than a plurality of lighting units, and also good in design.
And by using cold-cathode fluorescence lamp, the life-span of lighting unit is also longer, and with respect to the condition that repeats to light a lamp and turn off the light, durability is also good.Therefore, by in the lighting device that illuminates elevator cage inside, using, can set the maintenance period of the lighting device of elevator longer, therefore can reduce the operating cost of elevator.
Illustrate in greater detail above content with reference to above-mentioned the 1st execution mode, as shown in Figure 1, at a plurality of lighting units 10 of lighting device 1 inner configuration side by side.Lighting device 1 has the uniform light diffusing sheet 2 of light that is used to make from lighting unit 10 ejaculations.In this lighting unit 10, cold-cathode fluorescence lamp 11 has bend 111, and makes end 112 all in a side, and along three limits configurations of the peripheral part of pedestal 13.In other words, three limits along the peripheral part of pedestal 13 dispose cold-cathode fluorescence lamp 11.That is, can be configured to as the end 112 of non-illuminating part not adjacent to each other.
And, because cover 14 made by transparent component, so from not quilt cover 14 blockings of light of cold-cathode fluorescence lamp 11 radiation.As shown in Figure 1, by bend 111 sides of cold-cathode fluorescence lamp 11 are relatively arranged lighting unit 10, thus, as shown in Figure 2, with the light diffusing sheet 2 of the corresponding each other part of lighting unit 10 on, also supply with enough light quantities from bend 111.
Therefore, in the light diffusing sheet 2 that a plurality of lighting units 10 is configured in inboard lighting device 1, do not produce brightness disproportionation.And, up to the edge of ceiling 101, can both integral body luminous equably.Like this, in order to make homogeneous light emitting area, this lighting unit 10 is installed is side by side got final product.Make lighting unit 10 become the convenient suitable length of handling and produce in a large number, also manufacturing cost can be suppressed for lower thus.
And,, therefore can on the direction of illumination of light, reduce the thickness of lighting unit 10 owing to dispose converter 12 in the inboard that cold-cathode fluorescence lamp 11 is surrounded.And, owing on light diffusing sheet 2, be difficult to produce brightness disproportionation, so can dwindle distance as the cold-cathode fluorescence lamp 11 and the light diffusing sheet 2 of light source.
In addition, in the present embodiment,, be not limited to aforesaid way covering 14 when being fixed on the pedestal 13.For example, also can the peripheral part of pedestal 13 is bonding with the peripheral part of cover 14, projection, embedded hole or the hook etc. of mutual engaging also can be set.When bonding, can use adhesives, also can dissolve joint by ultrasonic wave.Make its when engaging, projection, embedded hole or hook etc. can be arranged on pedestal 13 and cover 14 either side, also miscellaneous part.
And according to the lighting device of 1 mode of the present invention, it is shaped as, and the end that makes cold-cathode fluorescence lamp built-in in becoming the lighting unit of light source is all in a side.The cold-cathode fluorescence lamp following degree of being turned back, the part of the inboard of its encirclement does not produce brightness disproportionation on light diffusing sheet.And converters is in the inboard of cold-cathode fluorescence lamp encirclement.That is, cold-cathode fluorescence lamp is along the periphery configuration of pedestal.
Therefore, because lighting device can each lighting unit of alignment arrangements,, so on light diffusing sheet, do not produce brightness disproportionation so that the cold-cathode fluorescence lamp of adjacent lighting unit distance each other is for uniformly-spaced.And, under the situation of alignment arrangements lighting unit,, also can make fully approaching mutually even the end of the cold-cathode fluorescence lamp of adjacent lighting unit is arranged side by side each other.That is, lighting device of the present invention in the light diffusing sheet corresponding with the end of cold-cathode fluorescence lamp part arranged side by side each other, can provide uniform lightness.
Below, with reference to Figure 10 to Figure 14, to when comparing with the 1st execution mode, the lighting device 1 of different respectively the 2nd execution mode to the 6 execution modes of the configuration of lighting unit 10 describes.In addition, have with the formation of the 1st execution mode identical function and use identical symbol, and omit its explanation.In the 2nd to the 6th execution mode, the internal structure of lighting unit 10 is for example identical with above-mentioned the 1st execution mode.
The lighting device 1 of the 2nd execution mode of the present invention is described with reference to Figure 10.The lighting unit 10 of lighting device 1 shown in Figure 10 constitutes a pair of opposite configuration group G2 of the mutual configuration of linearity relatively of end 112 sides that make cold-cathode fluorescence lamp 11, and this opposite configuration group G2 is arranged as parallel a plurality of state side by side.Lighting unit 10 is that at the inboard configuration converter 12 that cold-cathode fluorescence lamp 11 surrounds, and as shown in figure 10, the end 112 of cold-cathode fluorescence lamp 11 extends to than the position of bend 111 near the outer peripheral edges of pedestal.
Therefore, at non-luminous interval that the relative each other part in end 112 of the cold-cathode fluorescence lamp 11 of the lighting unit 10 of identical opposite configuration group G2 produces, with comparing, for enough little from the bend 111 of a cold-cathode fluorescence lamp 11 to parallel part distance each other arranged side by side the end 112 with cold-cathode fluorescence lamp 11 distance each other of the lighting unit 10 of adjacent opposite configuration group G2.And, with the end 112 corresponding light diffusing sheet 3 of part toward each other, can obtain enough light quantities from cold-cathode fluorescence lamp 11, therefore in the brightness of the light-emitting area 3a of light diffusing sheet 3, be difficult to produce inequality.
The lighting device 1 of the 3rd execution mode of the present invention is described with reference to Figure 11.The lighting unit 10 of lighting device 1 shown in Figure 11, constitute respectively make cold-cathode fluorescence lamp 11 bend 111 sides relatively and a pair of face-off configuration group G1 of linearity configuration is relative with end 112 sides that make cold-cathode fluorescence lamp 11 and opposite configuration group G2 that the linearity configuration is a pair of is configured to a plurality of states arranged side by side abreast that replace with them.As the 1st execution mode and the 2nd execution mode illustrated, no matter be face-off configuration group G1 or opposite configuration group G2, in the brightness of the light-emitting area 3a of light diffusing sheet 3, all be difficult to produce uneven.Therefore, face-off configuration group G1 and opposite configuration group G2 replace lighting device arranged side by side 1 too, also are difficult to produce uneven in the brightness of the light-emitting area 3a of light diffusing sheet 3.
The lighting device 1 of the 4th execution mode of the present invention is described with reference to Figure 12.The lighting unit 10 of lighting device 1 shown in Figure 12, linearity disposes a pair of configured in series group G3 with end 112 sides are relative mutually to constitute bend 111 sides that make cold-cathode fluorescence lamp 11, and they are arranged as a plurality of parallel states arranged side by side.Adjacent configured in series group G3 be configured in make bend 111 sides the position respectively on the direction on the same position.
The lighting device 1 of the 5th execution mode of the present invention is described with reference to Figure 13.The lighting unit 10 of lighting device 1 shown in Figure 13 is configured on bend 111 sides that the make configured in series group G3 direction consistent with end 112 sides of adjacent configured in series group G3.
In the lighting device 1 of the 4th and the 5th execution mode, adjacent lighting unit 10 is that bend 111 and end 112 are relatively arranged side by side.That is, the arbitrary limit along adjacent lighting unit 10 adjacent side each other necessarily is provided with cold-cathode fluorescence lamp 11.Therefore, in the brightness of light diffusing sheet 3, be difficult to produce inequality.
The lighting device 1 of the 6th execution mode of the present invention is described with reference to Figure 14.The size of lighting device 1 shown in Figure 14 is than lighting device 1 a big circle of the 1st to the 5th execution mode.Therefore, as light source and the quantity of built-in lighting unit 10 is more.In this lighting device 1, the state of the configuration of lighting unit 10 is, in bend 111 sides of face-off configuration group G1 each other, and to the direction of its crosscut being inserted face-off configuration group G1.In the present embodiment, to be made as aspect ratio be 6: 1 to the overall dimension of each lighting unit 10.The ratio of the overall dimension here is an example, in order to become various arrangements, also can be to wait other ratios in 4: 1 or 7: 2.
Next explanation is used for the lighting unit 10 of the lighting device 1 of the 7th execution mode of the present invention with reference to Figure 15 and Figure 16.In addition, about the formation of lighting device integral body or the arrangement of lighting unit 10, with reference to the 1st to the 6th execution mode.Have with the formation of the 1st to the 6th execution mode identical function and use identical symbol, and omit its explanation.In the 7th to the 12nd execution mode of following explanation, the internal structure of lighting unit 10 is for example identical with above-mentioned the 1st execution mode.
As shown in figure 15, lighting unit 10 has holding section 17a, the 17b that carries out with the location of adjacent lighting unit 10.This holding section 17a, 17b stretch out respectively from two sidepieces 130 of pedestal 13, and this pedestal 13 is along being arranged on bend 111 from cold-cathode fluorescence lamp 11 to the straight line portion between the end 112.On each sidepiece 130, be provided with one respectively near bend 111 with near end 112,4 holding section 17a, 17b altogether are set on a lighting unit 10.Each holding section 17a, 17b have the installing hole 171 towards main body 2 perforations of lighting device 1.
The lighting unit 10 of present embodiment is, in Figure 15, near the end 112 of the appreciable sidepiece 130 of side in the presence of be provided with and in face of the holding section 17a that extends of side, be provided with along the installation portion 4 of main body 2.In Figure 15, near the bend 111 of the appreciable sidepiece 130 of side in the presence of be provided with and in face of the holding section 17b that extends of side, as shown in figure 16, be arranged on the position that exceeds a little with respect to the installation portion 4 on the main body 2 that is arranged on lighting device 1.
In Figure 15, be provided with and the holding section 17a that extends to the inside near the bend 111 of the sidepiece 130 of the inside side, as shown in figure 16, be provided with along the installation portion 4 of main body 2.Be provided with and the holding section 17b that extends to the inside near the end 112 of the sidepiece 130 of the inside side, be arranged on from the position that installation portion 4 exceeds a little.In other words, a side and opposite side at the sidepiece 130 of pedestal 13 are respectively arranged with holding section 17a, 17b on the mutual rotational symmetric position.
Therefore, if identical shaped lighting unit 10 then can make bend 111 be adjacent to installation arranged side by side, also can make bend 111 and end 112 be adjacent to installation arranged side by side.As shown in figure 16, adjacent lighting unit 10 holding section 17a, 17b each other overlaps, and fixing by set bolt 5.
Because the lighting unit 10 of present embodiment has holding section 17a, 17b, so location and the installation each other of adjacent lighting unit 10 is easy.Because lighting unit 10 is fixed on the main body 2 by set bolt 5, so do not need fixed part 137 in the 1st execution mode and inserting hole 146 etc.And, in the 1st to the 6th execution mode, at the lighting unit 10 that becomes face-off configuration group G1, opposite configuration group G2 and configured in series group G3 each other, the parts that are equivalent to above-mentioned holding section 17a, 17b can be set also.
The lighting unit 10 of use in the lighting device 1 of the 8th execution mode of the present invention with reference to Figure 17 and Figure 18 explanation.In addition, about the formation of lighting device integral body and the arrangement of lighting unit 10, with reference to the 1st to the 6th execution mode.Have with the formation of the 1st to the 7th execution mode identical function and use identical symbol, and omit its explanation.Lighting unit 10 is compared with the lighting unit 10 of the 7th execution mode, the shape difference of holding section 17a, 17b.
