Thereafter, the second mounting spring 130-2 at the center is pulled down, and the second mounting spring 130-2 is inserted into the opening 252 of the second connector 250-2 provided substantially at the center of the light source unit 200. At this time, the operator can connect the tips of the first mounting spring 130-1 and the second mounting spring 130-2 inserted into the respective openings 252 of the first connecting tool 250-1 and the second connecting tool 250-2. The locking portion 133 a is hooked on the edge 252 a of the opening 252. Thereby, the light source unit 200 can be temporarily fixed to the instrument main body 100. Further, the worker engages the first mounting spring 130-1 with the first connector 250-1 by engaging the engaging portion 132 of the first mounting spring 130-1 with the contact portion 254. On the other hand, the tip end locking portion 133a of the second attachment spring 130-2 is hooked on the edge 252a of the opening 252 of the second connector 250-2. This state is shown in FIG. As shown in FIG. 8B, the light source unit 200 is attached obliquely to the instrument body 100 so as to have an acute angle θ.

  Therefore, the light source unit 200 and the instrument main body 100 are separated from each other on the third connector 250-3 side of the light source unit 200. For this reason, the work space for connecting the connector 222 of the electric wire 223 pulled out from the 2nd power supply device 200-2 and the connector 122 of the electric wire 123 drawn out from the power supply terminal block 121 can be ensured widely. Therefore, it is easy to connect the connector 122 and the connector 222, and workability is improved.

(Fig. 8 (c))
When the connection between the connector 122 and the connector 222 is completed, the operator inserts the third attachment spring 130-3 into the opening 252 of the third connector 250-3, and the tip locking portion of each attachment spring 130. 133a is hooked on the edge 252a of each opening 252 to the state shown in FIG. Then, the operator pushes up the light source unit 200 toward the instrument main body 100 and attaches the light source unit 200 to the instrument main body 100.

(Fig. 8 (d))
In the state of FIG. 8D, the engagement portions 132 of the three attachment springs 130 abut against the contact portions 254 of the corresponding couplers 250 and are engaged. In the state of FIG. 8D, as shown in FIG. 5, the light source unit 200 is pulled upward by the three attachment springs 130, which is the instrument body 100 side. In that case, the first light source unit side wall portion 201 and the second light source unit side wall portion 202 are in contact with the first upward movement restriction portion 113a-1 and the second upward movement restriction portion 113a-2, and Movement in the direction is restricted.

<*** Explanation of effects *****>
In the case of the conventional lighting device, when the light source unit is attached to the fixture body, depending on the shape of the light source unit, there is a possibility that the housing space of the fixture body may enter further inside. On the other hand, according to the illuminating device 1001, since the movement restricting portion having the upward movement restricting portion is provided, the light source unit 200 can be prevented from entering the concave portion 111 of the main body portion 110, and the light source unit can be prevented. 200 can be installed in place. Therefore, the attachment property when the operator attaches the light source unit to the instrument body is improved.

  Moreover, since the movement control part 113 is provided with the movement control part which has a horizontal direction movement control part, a horizontal direction movement control part becomes the positioning of a horizontal direction when an operator attaches a light source unit to an instrument main body. Therefore, the mountability when the worker mounts the light source unit to the instrument body is improved.

  When the first light source unit side wall 201 comes into contact with the first upward movement restricting portion 113 a-1, the first latch portion 114-1 moves upward in the first light source unit side wall 201. The lower part than the end part 201U is sandwiched between the inner surface 111-1a of the first instrument body side face part 111-1. Similarly, when the second light source unit side wall 202 comes into contact with the second upward movement restricting portion 113 a-2, the second latch portion 114-2 is positioned above the second light source unit side wall 202. The lower side than the end 202U in the direction is sandwiched between the inner surface 111-2a of the second instrument main body side surface portion 111-2. Therefore, even when the light source unit 200 is bent due to its own weight, the first latch portion 114-1 and the second latch portion 114-2 are connected to the upper end 201 U of the first light source unit side wall 201. The deflection of the light source unit 200 can be corrected by sandwiching the upper end 202U of the second light source unit side wall 202. That is, in FIG. 5, when the location of the maximum width W2 of the first light source unit side wall portion 201 is going to go below the position of the minimum width B1 of the first latch portion 114-1, W2> B1. Therefore, the 1st latch part 114-1 suppresses that the location of the maximum width W2 moves below. The same applies to the second latch unit 114-2. Thus, the latch part 114 can suppress the downward movement of the light source unit 200 due to its own weight.

  When the light source unit 200 is removed from or attached to the instrument main body 100, the upper end 201U of the first light source unit side wall 201 and the upper end of the second light source unit side wall 202 are disposed. The portion of the portion 202U having the maximum width W2 passes through the portion of the minimum width B1 of each latch portion 114. At this time, the latch portions 114 are elastically deformed in the lateral direction E depending on the location of the maximum width W2, so that there is an appropriate feeling of wearing, and the operator can recognize the attachment / detachment state of the light source unit 200.

In the first embodiment, as shown in FIG. 8C, the power supply terminal block 121 arranged in the instrument main body 100 and the second power supply device 220-2 are connected by the connectors 122 and 222, and the first power supply is connected. The device 220-1 is configured to receive power supply from the power supply terminal block 121 via the second power supply device 220-2. In addition to this configuration, the configuration shown in FIG. 13 may be used.
FIGS. 13A and 13B correspond to FIGS. 8C and 8D, respectively. As shown in FIG. 13A, the light source unit 200 includes a power terminal block 261 disposed on the other surface 210-3b of the mounting portion 210. The power terminal block 261 includes an electric wire 263 to which a connector 262 is attached. The connector 262 is connected to the connector 122 of the power terminal block 121. The first power supply device 220-1 is connected to the power supply terminal block 261 by an electric wire 264, and the second power supply device 220-2 is connected to the power supply terminal block 261 and an electric wire 265. Therefore, the first power supply device 220-1 and the second power supply device 220-2 receive power supply from the power supply terminal block 121 through the power supply terminal block 261. In this way, by providing the power terminal block 261 also on the light source unit 200 side, power can be supplied to each power supply device independently, so that it is possible to easily cope with the case where the number of power supply devices is to be changed.
As shown in FIG. 13A, the power terminal block 121 and the power terminal block 261 are displaced in the longitudinal direction X. For this reason, when the light source unit 200 is attached to the instrument main body 100 as shown in FIG. 13B, interference between the power terminal block 121 and the power terminal block 261 can be prevented in the vertical direction Z.

  In the first embodiment, it has been described that the two power supply devices 220 are arranged in the light source unit 200. However, the two power supply devices 220 may be arranged in the instrument main body 100.

Embodiment 2. FIG.
A lighting apparatus 1002 (not shown) according to the second embodiment will be described with reference to FIGS. In the second embodiment, differences from the first embodiment will be described. The illumination device 1002 according to Embodiment 2 has a configuration in which the arrangement of the LEDs 231 in the light source unit 200 is determined with respect to the illumination device 1001.

  FIG. 14 is a diagram showing the arrangement of the LEDs 231 and shows the arrangement of the LEDs 231 when viewed from the direction F of FIG. In the first LED module 230-1, a plurality of LEDs 231 are linearly arranged on the longitudinal substrate 232 along the longitudinal direction X of the substrate 232 at equal intervals X1. Similarly, in the second LED module 230-2, a distance X1 between the LEDs 231 in which a plurality of LEDs 231 are arranged in the first LED module 230-1 along the longitudinal direction X of the substrate 232 on the long substrate 232. Are arranged linearly at the same interval X1. The plurality of LEDs 231 arranged in the first LED module 230-1 are arranged in a line with the plurality of LEDs 231 arranged in the second LED module 230-2. In FIG. 14, the interval X <b> 1 is given only to the four LEDs 231, but the interval between the other LEDs 231 arranged on the same substrate 232 is also the interval X <b> 1. Further, the interval between the rightmost LED 231-1 of the first LED module 230-1 and the leftmost LED 231-2 of the second LED module 230-2 is an interval X2. In FIG. 14, a region 215 exists as a gap between the first LED module 230-1 and the second LED module 230-2, and one surface 210-3a of the light source mounting portion 210-3. Appears. The region 215 prevents the LED modules 230 from extending and interfering with each other in the longitudinal direction X due to thermal expansion.

The LED 231-1 is closest to the second LED module 230-2 among the plurality of LEDs 231 of the first LED module 230-1, and the LED 231-2 is the first of the plurality of LEDs 231 of the second LED module 230-2. It is closest to the LED module 230-1. An interval X2 between the LED 231-1 and the LED 231-2 is in a range of 0.5 to 2 times the interval X1.
In other words, if expressed as an expression,
0.5X1 ≦ X2 ≦ 2X1
It is a relationship.

The reflectance of the region 215, that is, the reflectance of the one surface 210-3a appearing in the region 215 is greater than the reflectance of each substrate 232 of the first LED module 230-1 and the second LED module 230-2. If low,
In other words,
When the reflectance of the region 215 <the reflectance of the substrate 232, the interval X2 is made shorter than the interval X1. Thereby, the continuity of light can be improved. On the other hand, when the reflection of the one surface 210-3a in the region 215 is higher than the reflectance of each substrate 232 of the LED module 230,
In other words,
When the reflectance of the region 215> the reflectance of the substrate 232, the continuity of light can be made substantially constant even if the interval X2 is longer than the interval X1.

<Interval X1, Interval X2>
In FIG. 14, the distance X1 and the distance X2 between the LEDs 231 are distances in the longitudinal direction X of the light source mounting portion 210-3 between the center positions of the light emitting surfaces of the adjacent LEDs 231. In addition, as shown in FIG. 15A, a reference location in each LED 231 is determined, and the LEDs are arranged so that the intervals in the longitudinal direction X between the reference locations are the interval X1 and the interval X2. Good. In FIG. 15A, the left side surface of the LED 231 is used as a reference location. Further, as shown in FIG. 15B, a reference location may be determined and marked, and the LEDs may be arranged such that the mark interval in the longitudinal direction is the interval X1 and the interval X2. The method of determining the interval X1 and the interval X2 is not limited to the above example as long as the continuity of light can be made substantially constant.

  In the second embodiment, the two power supply devices 220 are attached to the light source unit 200. That is, in Embodiment 2, the two power supply devices 220 having the longitudinal shape shown in FIG. 10 are attached to the other surface 210-3b of the light source attachment portion 210-3. And as FIG. 10 shows, the 1st power supply device 220-1 is attached to the other surface 210-3b along the longitudinal direction X of the light source attachment part 210-3, and electric power is supplied to the 1st light source module 230-1.

Further, the second power supply device 220-2 is arranged in a line with the first power supply device 220-1 along the longitudinal direction X of the light source mounting portion 210-3, and is the second light source portion 8230-2. Power is supplied to the second LED module 230-2. As shown in FIG. 14, the first LED module 230-1 and the second LED module 230-2 have connectors 311-1 and 312-1, respectively. The first LED module 230-1 is supplied with power from the first power supply device 220-1 via the connector 311-1, and the second LED module 230-2 is supplied to the second power supply device via the connector 312-1. Power is supplied from 220-2.

  In the light source unit 200 of the second embodiment, the first power supply device 220-1 and the second power supply device 220-2 are arranged in a line on the other surface 210-3b. Therefore, since the light source unit 200 has a good weight balance, the attachment property when the operator attaches the light source unit 200 to the instrument main body 100 is improved.

  In the light source unit 200 according to the second embodiment, the LEDs are arranged in the two LED modules 230 at equal intervals with the interval X1, so that there is an effect that the weight balance is good.

  In the light source unit 200 of the second embodiment, the interval X2 is set to be in the range of 0.5 times or more and twice the interval X1, so that the light depends on the reflectivity of the substrate 232 and the one surface 210-3a. Can be ensured.

Embodiment 3 FIG.
The illumination device 1003 according to Embodiment 3 will be described with reference to FIGS. In the third embodiment, differences from the first and second embodiments will be described. The feature of the third embodiment is that the length L (2) of a beam portion 135 (to be described later) in the spring longitudinal direction 139 of the second mounting spring 130-2 disposed on the instrument main body 100 is the other two mounting springs 130. Longer than that. Thereby, the work space indicated by the broken line 313 in FIG.

(C) shows immediately before lifting the light source unit 200 in the direction of the instrument body 100.
(D) shows a state where the light source unit 200 is attached to the instrument body 100.

  The illumination device 1003 of the third embodiment is different from the illumination device 1001 of the first embodiment in that the length of the beam portion 135 in the spring longitudinal direction 139 of the second attachment spring 130-2 is the first attachment spring 130. -1, longer than the beam portion 135 of the third attachment spring 130-3.

  The elongated instrument body 100 includes three attachment springs 130 that are longitudinal leaf springs. In the third embodiment, the longitudinal direction X is also referred to as the longitudinal direction X. The three attachment springs 130 are arranged along the longitudinal direction X of the instrument main body 100, one end on the left side of the instrument main body 100 in the longitudinal direction X, the other end, one end, and the other end. The spring longitudinal direction 139 is arranged in the instrument main body 100 with the longitudinal direction X facing the portion sandwiched between them.

  As shown in FIG. 11, the three attachment springs 130 have a fixing portion 131 and a beam portion 135. The fixing portion 131 is formed at one end portion in the spring longitudinal direction 139 and is fixed to the instrument main body 100. The beam portion 135 is formed integrally with the fixed portion 131 and functions as a cantilever beam. The beam portion 135 has a distal end locking portion 133a that is a bent portion 8133a having a bent shape at an end that is the end of the spring longitudinal direction 139. The beam portion 135 includes an engaging portion 132 and an arc portion 133 having a tip engaging portion 133a formed at the end thereof, and has an arc shape.

As shown to Fig.16 (a), the 2nd attachment spring 130-2 arrange | positioned between the two attachment springs which are the 1st attachment spring 130-1 and the 3rd attachment spring 130-3 is as follows. A feature of the present embodiment is that the beam length L (2) in the spring longitudinal direction 139 is longer than the two mounting springs. That is, the beam lengths of the first mounting spring 130-1, the second mounting spring 130-2, and the third mounting spring 130-3 are L (1), L (2), and L (3), respectively. If
L (2)> L (1) and L (2)> L (3)
It is.

  Further, as shown in FIG. 16A, the first attachment spring 130-1 and the third attachment spring 130-3 are arranged so that the spring longitudinal direction 139 faces the opposite direction. In FIG. 16A, the spring longitudinal directions 139 of the first attachment spring 130-1 and the third attachment spring 130-3 are directed to the left and right, respectively. The spring longitudinal direction 139 of these attachment springs 130 may be a spring arrangement facing the right direction and the left direction, respectively.

  The arrangement of the three mounting springs 130 when viewed from the direction F in FIG. 16A is the same as that in FIG. 3, and the three mounting springs 130 are arranged in a row along the longitudinal direction X of the instrument body 100. Are arranged in a straight line or in a straight line.

  In FIG. 16D, the three connecting tools 250 are connected to the mounting springs of the three mounting springs in a one-to-one correspondence and are pulled by the spring force. As a result, the light source unit 200 is attached to the instrument body 100.

  In the third embodiment, the beam length L (2) in the spring longitudinal direction 139 is longer than the beam lengths L (1) and L (3) of the other two attachment springs 130. For this reason, in FIG. 8B, in the state where the vertical dimension is the length H1, the distal end locking portion 133a of the second mounting spring 130-2 is hooked on the edge 252a of the second connector 250-2. However, in FIG. 16B, when the vertical dimension is the length H1, the arc portion 133 still remains up to the distal end locking portion 133a, and the arc portion 133 extends to the length H2. Therefore, a wider space for the connector mounting operation indicated by the broken line 313 can be secured than in the first embodiment.

  In addition, in the state of FIG. 16D in which the light source unit 200 is attached to the instrument main body 100, the engaging portion 132 of the first attachment spring 130-1 and the third attachment spring 130-3, and the second The engaging portions 132 of the mounting springs 130-2 abut on the abutting portions 254 of the corresponding couplers 250 to hold the light source unit 200. That is, the connection state of each attachment spring 130 in FIG. 16D and the corresponding connector 250 is the same as that in FIG. Therefore, the beam portion length L (2) of the second mounting spring 130-2 is longer than the beam lengths L (1) and L (3) of the other two mounting springs 130, so that the connector 250 There is no concern about a decrease in holding power of the light source unit 200.

  According to the instrument main body 100 of the third embodiment, the mounting spring disposed between the two mounting springs has a longer beam length in the longitudinal direction X than the two mounting springs. A wide working space can be ensured by hooking the bent portion of the mounting spring disposed between the light source unit parts. Therefore, the attachment property when an operator attaches the light source unit to the instrument body is improved.

  In the third embodiment, it is assumed that one power supply device 220 is arranged in the light source unit 200 as in the first embodiment. However, one power supply device 220 may be arranged in the instrument main body 100.

Accordingly, the light source unit 200 is attached to the instrument body 100 by rotating around the holding portion 140 as a rotation center. That is, the operator rotates the light source unit 200 around the insertion portion 280 in the state of FIG. 23A inserted into the opening 141 as the center of rotation, and FIG. Set to the state of (d). FIG. 23B is a cross-sectional view showing the relationship between the holding part 140 and the insertion part 280 in FIG. In FIG. 23B, the upper surface 240-1-1 of the light source lid part 240-1 is in contact with the bottom surface 118-1-1 of the end plate part 118-1, and the hooking sliding part 286 is in the F2 direction. It is elastically deformed and presses the edge 142 in the anti-F direction.

  As described above, according to the fourth embodiment, the lighting device 1004 includes the holding unit 140 and the insertion unit 280. Therefore, when the long light source unit 200 is attached to the instrument body 100, the first attachment spring 130-1 is provided. Need not be attached to the first connector 250-1, and the insertion part 280 may be inserted into the opening 141 of the holding part 140. Therefore, the effect that the operator does not need to move toward the first attachment spring 130-1 can be obtained.

  Further, in the lighting device 1004, the corresponding connector 250 is pushed in the insertion direction 289 by the two attachment springs 130, so that there is an effect that the insertion portion 280 is not easily detached from the opening 141.

  In the fourth embodiment, it is assumed that one power supply device 220 is arranged in the light source unit 200 as in the first embodiment. However, one power supply device 220 may be arranged in the instrument main body 100.
