First, perform the operator of assembly program by electric power supply apparatus 4 be attached to attachment members 21 second surface (on Surface) so that the bottom plate 211 that the opening (lower surface) of housing 42 is attached component 21 is closed.Now, operator is by retainer 53 End (lower end) insertion formed in hole 213 in bottom plate 211 (referring to Fig. 5 and Fig. 8).That is, hole 213 is in bottom plate 211 second surface (upper surface) side is surrounded by the housing 42 of electric power supply apparatus 4 and with the envelope of housing 42 of electric power supply apparatus 4 Close (referring to Fig. 2 and Fig. 8).Therefore, according to the light source cell 2 of the present embodiment, the foreign matter of such as insect and/or dust can be limited The first surface side of bottom plate 211 is entered from the second surface side of bottom plate 211 by hole 213.

Then, LED module 22 is fixed to the first surface (lower surface) of the bottom plate 211 of attachment members 21 by operator.This When, when from from the thickness direction of substrate 221 (above-below direction), it is attached to two first of the substrate 221 of LED module 22 Each in terminal component 51 is arranged in the opening position overlapping with the corresponding slot 531 of two slots 531 of retainer 53 (referring to Figure 11).That is, hole 213 is by the substrate 221 of the LED module 22 on first surface (lower surface) side of bottom plate 211 Closing is (referring to Figure 11).Therefore, the light source cell 2 of the present embodiment is no longer needed for the component of blind hole 213 (for example, having Put on the band of the adhesive of side), so as to reduce the quantity of component and manufacturing step to reduce cost.

Then, operator by each in two conductors 50 be inserted into two the first terminal components 51 corresponding to one In patchhole 511 in individual terminal component.Now, it is arranged to surround three support chips 512 and three guide plates of patchhole 511 The upper end (the second end 501) of conductor 50 is directed to patchhole 511 by 513 lower surface (inclined surface).Therefore, operator can be with Easily conductor 50 is inserted into patchhole 511.Pay attention to, when tip portion 5120 contacts with conductor 50, three support chips 512 on (upward) direction that conductor 50 inserts respective warpage (elastic deformation).

Each conductor 50 is inserted into patchhole 511 by operator, reach conductor 50 lower end substantially with board member 510 The opening position that flushes of lower surface.Now, the upper end (the second end 501) of two conductors 50 passes through the slot 531 of retainer 53, and And each it is inserted in the first spring leaf 520A and second spring piece of the corresponding terminal component in Second terminal component 52 Between 520B.That is, the second end 501 of each conductor of two conductors 50 is clipped in the first spring leaf in the longitudinal direction Between 520A and second spring piece 520B, so as to which each conductor in conductor 50 is electrically connected in Second terminal component 52 Corresponding one (referring to Figure 11).The first end 500 of each conductor in two conductors 50 is clamped with three support chips 512, Corresponding to each conductor in conductor 50 is electrically connected in the first terminal component 51 one (referring to Figure 11).Knot Fruit, connecting elements 5 will be each electrically connected to (the electric power of electric power supply apparatus 4 in two input terminals 222 of LED module 22 Supply circuit 49) two lead-out terminals 405 in corresponding one (referring to Figure 11).

Finally, cover 23 is attached to attachment members 21 by operator, wherein the opening upwards of attachment members 21 towards.Now, Set a pair of a pair of side plates 212 that a pair of cover 23 a pair of projection 233A for protruding wall portions 233 are hooked in attachment members 21 and incline On inclined portion 212A, cover 23 is attached to attachment members 21.According to said procedure, light source cell 2 is assembled.

Here, in the light source cell described in document 1, electric power supply apparatus is electrically connected to the connector of LED module Electric wire insertion attachment members through hole in.Therefore, in the light source cell described in document 1, it is difficult to simplify light source cell Assembling process (manufacturing process).

On the contrary, as described above, the light source cell 2 of the present embodiment is configured such that by will be each in two conductors 50 Complete to fill supply of electric power in patchhole 511 in the individual corresponding terminal component being inserted into the first terminal component 51 Put 4 processes for being electrically connected to LED module 22.Therefore, according to the light source cell 2 of the present embodiment, with the light described in such as document 1 The convenient example of source unit is compared, and can simplify (light source cell 2) manufacturing process.

In addition, in the light source cell 2 of the present embodiment, each in two the first terminal components 51 arrives plate including setting Three support chips 512 of component 510.Each in these three support chips 512, which is formed integrally as with board member 510 surrounding, inserts Enter hole 511.In addition, three support chips 512 by be inserted through patchhole 511 conductor 50 (first end 500) press and Elastic deformation.In addition, three support chips 512 via the tip portion 5120 pressed by the first end 500 of conductor 50 each with leading Body 50 electrically connects.That is, according to the light source cell 2 of the present embodiment, even if when conductor 50 is relative to inserting in board member 510 When entering hole 511 and tilting, the elasticity of multiple (such as three) support chips 512 cause the tip portion 5120 of each support chip 512 with Conductor 50 contacts.As a result, the light source cell 2 of the present embodiment can extend each other corresponding two the first terminal components one to one 51 and two Second terminal components 52 position skew allowed band.In addition, in two the first terminal components 51 of solder joints Each terminal component 510 to two input terminals of board member 222 in corresponding to an input terminal stress less Easily by the inclined influence of conductor 50.Therefore, for example fixed with the first terminal component 51 and conductor 50 by solder joints In the case of, when (board member 510) of solder joints the first terminal component 51 arrives input terminal 222, it is unlikely to occur rupture.

Here, the substrate 221 of LED module 22 is due to the warm that is exported from the LED 220 that lights and to the power supply phase of LED module 22 Between from electric supply installation 4 export heat and expand.Form the linear expansion system of the synthetic resin (for example, epoxy resin) of substrate 221 Number is more than tens times of the linear expansion coefficient for the metal (for example, zinc steel plate or stainless steel plate) to form attachment members 21.Base Each in multiple grooves 2211 in plate 221 is formed so that the length of longitudinal direction of each groove 2211 along substrate 221 Length than the body 2160 of hook 216 is longer.That is, substrate 221 is with the length of longitudinal direction of the groove 2211 along substrate 221 Difference between the length of (body 2160) of degree and hook 216, it is removable relative to attachment members 21 in a longitudinal direction.Therefore, Even if when the thermal expansion amount of substrate 221 is more than the thermal expansion amount of attachment members 21, substrate 221 is in a longitudinal direction relative to attached The movement of connection member 21 makes it possible to reduce the stress for being applied to substrate 221 by the hook 216 of attachment members 21.

However, substrate 221 makes the first end fixed to substrate 221 relative to the movement of attachment members 21 in a longitudinal direction Sub- component 51 and be indirectly secured via housing 42 attachment members 21 Second terminal component 52 relative offset.As above It is described, even if position relative to each other is inclined to a certain extent when the first terminal component 51 and Second terminal component 52 to correspond to each other During shifting, connecting elements 5 can be kept electrically connecting via conductor 50.However, when substrate 221 is relative to the amount of movement of attachment members 21 More than connecting elements 5 the first terminal component 51 and Second terminal component 52 position skew allowed band when, via conductor Electrical connection 50 can not keep.For example, it is assumed that in the vertical direction, relative to the patchhole 511 in the first terminal component 51 The overlapping opening position of middle body of the middle body with the first spring leaf 520A and second spring piece 520B in the lateral direction, position The allowed band for putting skew is ± 1.6 [mm] (referring to Figure 11).In this case, if substrate 221 is relative to attachment members 21 amount of movement is limited in equal to or less than 1.6 [mm], preferably 1.4 [mm] below, then LED module 22 and supply of electric power circuit It is kept between 49 via the electrical connection of connecting elements 5.

When light source cell 2 is closed, the longitudinal direction in the groove 2211 of substrate 221 is connected in the body 2160 of hook 216 On one end (first end) on side surface under state, in body 2160 and the other end on the longitudinal direction of groove 2211 The distance between the side surface at (the second end) is represented (referring to Figure 13) by Y1.Now, the indulging along attachment members 21 of body 2160 Length to direction and the length of the groove 2211 along the longitudinal direction of substrate 221 are determined so that distance Y1 is less than or equal to Absolute value (for example, 1.6 [mm] or 1.4 [mm]).Pay attention to, the swell increment of substrate 221 is not necessarily uniformly.Thus, it is supposed that On the longitudinal direction of substrate 221 through center imagining center line α (referring to the long dotted line short dash line in Figure 12) on the basis of line, then Distance Y1 is determined based on the distance away from datum line along the longitudinal direction.Here, from datum line (center line α) to groove 2211 The distance of one end represents by Y11, and represented from datum line (center line α) to the distance at the second end of groove 2211 by Y12 (referring to Figure 12).Distance Y1 is confirmed as subtracting along the vertical of body 2160 by the poor absolute value between distance Y11 and distance Y12 The value obtained to the value of the length in direction.

In addition, the length of all grooves 2211 must not necessarily is fulfilled for the relation with the allowed band of above-mentioned position skew.Only It is required that the length for the groove 2211 being arranged between datum line (center line α) and the first terminal component 51 meets to offset with above-mentioned position Allowed band relation.In addition, in the light source cell 2 of the present embodiment, electric power supply apparatus 4 is in the longitudinal direction of attachment members 21 It is arranged on direction relative to datum line (center line α) on the side at the place of the first terminal component 51.That is, in substrate In 221, the temperature of the part between datum line (center line α) and the first terminal component 51 easily and relative increase, and therefore, The possibility of the swell increment of the part is relatively large.Here, electric power supply apparatus 4 is attached to attachment members 21 with following orientation, I.e. supply of electric power input block 400 is located at the opening position adjacent with the center (center line α) on the longitudinal direction of attachment members 21. On the printing distributing board 40 of electric power supply apparatus 4, the common mode choke coil as the circuit block with relative golf calorific value 4010 are arranged on supply of electric power input block 400 nearby (referring to Fig. 4).That is, electric power supply apparatus 4 is defeated in supply of electric power Entering tends to have of a relatively high temperature on the side that unit 400 is installed on the longitudinal direction of printing distributing board 40.Therefore, such as Shown in Figure 13, multiple (it is in example shown in the figure when being set between datum line (center line α) and the first terminal component 51 Two) groove 2211 when, it is only necessary to the length made closer to the groove 2211 of datum line (center line α) be defined as meet with above-mentioned position The relation of the allowed band of skew.
