Further, as shown in FIG. 24, the holder 9 has an elastic portion 930 in the vicinity of the edge of the recess 903. The elastic part 930 is formed with a protrusion 931 on the side where the optical control member 6 is disposed. When the protrusion 931 contacts the optical control member 6, the optical control member 6 is pressed by the elastic portion 930, and the optical control member 6 is pressed against the L-shaped rib 901. Thereby, the thickness of the optical control member 6 can be absorbed, and the positional deviation of the optical control member 6 in the optical axis direction can be suppressed.

  As described above, the optical control member 6 is slid in the P2 direction, and the flange portion 62 is inserted into the L-shaped rib 901. The L-shaped rib 901 presses the flange portion 62 and restricts the vertical direction of the optical control member 6. Further, the concave portion 903 and the convex portion 905 prevent the inserted optical control member 6 from coming off.

<< Assembly of light source unit 50 >>
Since the light source 5, the holder 9, the heat radiating plate 7, the heat conduction sheet 8, and the optical control member 6 can be unitized as the light source unit 50, the assembly work of the instruments can be divided and performed as a pre-work. The width expands.

The assembly of the light source unit 50 including the light source 5, the holder 9, the heat radiating plate 7, the heat conductive sheet 8, and the optical control member 6 will be described.
(1) First, the light source 5 in a state where one end side of the harness 10 is inserted into the holder 9 is disposed. At this time, the position of the light source 5 is determined by combining the substrate positioning portion 93 and the curved portion of the light source substrate 51.
(2) After placing the light source 5, the harness 10 is pushed into the harness holding portion 981. As a result, the harness 10 is fixed and stress is not applied to the connector 53 of the light source 5. Thereafter, the harness 10 is hooked on the harness holding portion 982 and passed through the harness holding portion 983. Thereby, it is possible to prevent the harness 10 from being sandwiched when the heat radiating plate 7 is attached and damage to the covering of the harness 10 due to the edge of the heat radiating plate 7.
(3) Thereafter, the heat conductive sheet 8 is placed on the substrate back surface 512 of the light source substrate 51, and the attachment claws 92 of the holder 9 are inserted into the square holes 73 of the heat sink 7. Thereby, the heat sink 7 and the heat conductive sheet 8 can be temporarily fixed to the holder 9. Temporarily fixing prevents the light source 5 from coming off and improves workability.
(4) Next, the optical control member 6 is attached to the member arrangement surface portion 920 of the holder 9. The optical control member 6 is fitted into the L-shaped rib 901 by sliding in the horizontal direction (P2 direction in FIG. 22B). At that time, the concave portion 903 and the convex portion 905 provided in the holder 9 prevent the holder 9 from being unexpectedly detached. By setting the optical control member 6 to slide in the horizontal direction (P2 direction), in the instrument mounting state, the L-shaped rib 901 is subjected to its own weight in the vertical direction. Therefore, as long as the L-shaped rib 901 is not damaged, the optical control member 6 is not detached from the holder 9 and dropped.
(5) After the optical control member 6 is attached, the position of the optical control member 6 is fixed by bending the hinge portion 902, and the optical control member 6 does not come off the holder 9 because it cannot slide. As shown in FIG. 22B and FIG. 24B, the hinge portion 902 has a resin hinge structure integrated with the holder 9, thereby reducing the number of parts and enabling cost reduction. The hinge portion 902 may be a separate member.
(6) Finally, the assembly of the light source unit 50 is completed by using two screws 911 and fixing to the heat sink 7 from the holder 9 side. By fixing with the screws 911, the substrate pressing portion 94 of the holder 9 presses the light source substrate 51 against the heat conductive sheet 8 and the heat radiating plate 7 so that the heat is efficiently radiated.

  As shown in FIGS. 19, 20, and 21, when there are a plurality of types of the light source 5 and the optical control member 6, a plurality of types of light source units 50 are formed by the combination of the light source 5 and the optical control member 6. Moreover, even when there are a plurality of types of power supply units 4, the structure is effective in improving the assembly efficiency of the operator.

The hook 151 is provided in the case 15 of the power supply unit 4. The screw attachment portion 134 and the hook portion 135 are provided on the attachment fitting 13.

<Frame 14>
As shown in FIG. 4, the frame 14 is attached to the main body 2 so as to close the opening 22 of the main body 2. The frame 14 covers the lower surface side of the light source unit 50. A frame opening 143 corresponding to the optical control member 6 is provided at the center of the frame 14. The frame opening 143 exposes the optical control member 6 of the light source unit 50.
The frame 14 has holes corresponding to the push buttons 43, the monitor LEDs 42, and the signal reception unit 41. A frame holding spring 141 for attaching to the main body 2 is attached to the frame 14. The frame 14 is held by the main body 2 by fitting the frame holding spring 141 to the frame mounting portion 32 of the main body 2. In the present embodiment, the same two frame holding springs 141 are used, but one or three or more may be used. Moreover, when using two or more, it is not necessary to make it the same shape, and it is good also as another shape according to the function requested | required. As an example of another shape, there is a shape in which one side is a leaf spring as in the present embodiment, and the other is a wire spring (V spring), which allows temporary holding.

<About the vertical movement of the light source unit 50>
As shown in FIGS. 30 to 32, the light source unit 50 is movable in the vertical direction while being fixed to the power supply unit 4 so that the back surface of the substrate faces upward. That is, the light source unit 50 is movable in the vertical direction with the light source attached to the power supply unit 4 so that the light source faces downward. “Moveable in the vertical direction” means that the light source unit 50 is wobbled in the vertical direction in the state shown in FIGS. The vertical direction is also referred to as a drop direction or a vertical direction.

  As shown in FIG. 9, the case 15 of the power supply unit 4 has a pair of bearing portions 155 to which the pair of shaft portions 91 a of the holder 9 are attached. As shown in FIGS. 12 and 18, the shaft portion 91a is pushed into the bearing portion 155 in the P5 direction. At this time, the shaft portion 91 a is pushed into the bearing portion 155 while the taper 911 a (FIG. 18) of the shaft portion 91 a contacts the inclined portion 155 a of the bearing portion 155. Thus, since the taper 911a is formed on the shaft portion 91a and the inclined portion 155a is formed on the bearing portion 155, the shaft portion 91a can be easily attached to the bearing portion 155.

The position stop portion 97 stops the light source unit 50 at the power source portion 4 so that the back surface of the substrate faces upward, that is, the light source faces downward, with the shaft portion 91a attached to the bearing portion 155. As shown in FIG. 18, the positioning portion 97 protrudes from the heat radiating plate 7. In addition, as shown in FIG. 12, the power supply unit 4 is formed with a long hole 166 into which the positioning portion 97 is inserted.
As shown in FIG. 23, the stop portion 97 is formed with a stop portion 97 a having a large width at the end portion. In addition, the position stop portion 97 is formed with a slit for cutting the stop portion 97a. The position stopper 97 is inserted into the elongated hole 166 while narrowing the slit. When the stopper 97a passes through the elongated hole 166, the slit returns to the original position and the stopper 97a cannot be removed from the elongated hole. The position stop portion 97 has a clearance L1 from the root to the stop portion 97a. For this reason, the positioning stop 97 is movable in the vertical direction while being inserted into the elongated hole 166. In other words, the positioning portion 97 has a backlash in the vertical direction in a state where it is inserted into the elongated hole 166.

  The enlarged view of FIG. 12 is a schematic diagram showing the shaft portion 91a and the shaft base portion 91b in the bearing portion 155 in a state where the light source unit 50 is stopped by the power source unit 4 so that the light source faces downward. As shown in the enlarged view of FIG. 12, the shaft base portion 91b is formed so that the upper portion becomes a planar portion 911b having a planar shape when the light source unit 50 is stopped by the power source portion 4 so that the light source faces downward. Is formed. Since there is a clearance L2 between the upper end portion of the bearing portion 155 and the planar portion 911b, the light source unit 50 is stopped by the power supply unit 4 so that the light source faces downward in the shaft portion 91a and the shaft base portion 91b. In this state, it can be moved up and down. That is, the shaft portion 91a and the shaft base portion 91b are wobbled in the vertical direction in a state where the light source unit 50 is stopped by the power source unit 4 so that the light source faces downward.

  As described above, in the light source unit 50, in the state shown in FIGS. 30 to 32, the shaft portion 91a, the shaft base portion 91b, and the position stop portion 97 attached to the power supply unit 4 are movable in the vertical direction, that is, the dropping direction. Is possible. Therefore, the light source unit 50 is movable in the vertical direction in the states of FIGS. 30 to 32, that is, has a rattling in the vertical direction.

As shown in FIG. 32, a protrusion 904 is formed on the member arrangement surface portion 920 of the holder 9. The protrusions 904 are formed at four positions on the peripheral edge portion of the member arrangement surface portion 920 of the holder 9.
By moving the light source unit 50 in the vertical direction, the light source unit 50 is regulated horizontally with respect to the frame 14, and a desired light distribution can be obtained with high accuracy. Further, in order to make the light source unit 50 movable in the vertical direction, as shown in the enlarged view of FIG. 12, the cross-sectional shape of the shaft base portion 91b of the holder 9 is not a circle but a substantially semicircular shape.

  In a model in which the output of the light source 5 is small, the heat radiating plate 7 may not contact the frame 14 as in the present embodiment. Such a model is desired to be as small as possible without contacting the frame 14. Even when the heat sink 7 does not contact the frame 14, the projection 904 of the holder 9 has a function of regulating the light source unit 50 in the horizontal direction with respect to the frame 14 by contacting the frame 14.

The number of storage battery cells 115 housed in the case 114 can be changed according to the light output required for the lighting device 1, and one type of case 114 can support various output forms of the lighting device 1. It becomes possible.
Further, the storage battery 11 is formed with a connector portion 111 so that a surface opposite to the surface having the connector portion 111 can be brought into contact with the power source portion 4 and can be housed inside the main body 2. This is because, when the lighting fixture 1 is stored in a package, it can be stored in the main body 2 without making an electrical connection, so that the storage battery 11 need not be separately disposed outside the main body 2 and packed. There exists an effect which miniaturizes the packing form of the lighting fixture 1. FIG.
