The substrate 212 of the light emitting module 210 is longer than the frame 220 in the longitudinal direction (X-axis direction) and has a length substantially equal to that of the cover 230 . Therefore, when the light emitting module 210 is mounted on the frame 220 , the substrate 212 has both ends 212 t protruding from the frame 220 .

The light emitting element 211 is a light source of the light source unit 200 and emits light when power is supplied.

The light-emitting elements 211 are not limited to being linearly mounted on the substrate 212 . It may be implemented in a shape or the like. The light-emitting element 211 is, for example, a surface-mounted component in which a phosphor for wavelength-converting blue light to yellow light is placed on an LED chip that emits blue light with a wavelength of 440 to 480 [nm] and packaged. It is a pseudo-white LED element. Note that the light emitting element 211 is not limited to a light emitting diode element. For the light emitting element 211, for example, a solid state laser, a semiconductor laser, an organic EL (Electro Luminescence), an inorganic EL, or the like may be used.

The frame 220 has a first plate portion 221 forming a board mounting surface 221a to which the light emitting module 210 is mounted. In addition, the frame 220 includes a column portion 222 protruding from a surface of the first plate portion 221 opposite to the substrate mounting surface 221a, and a second plate portion 221 provided to face the first plate portion 221 so as to sandwich the column portion 222. and a plate portion 223 .

The first plate portion 221 has a board mounting surface 221 a to which the light emitting module 210 is mounted and a cover holding portion 221 b that holds the cover 230 . The board mounting surface 221 a faces the cover 230 when the cover 230 is mounted on the frame 220 . The cover holding portion 221b is formed along the longitudinal direction (X-axis direction) of the frame 220 at the end of the frame 220 in the lateral direction (Y-axis direction). The cover holding portion 221b is formed in a hook shape and has an L-shaped cross section. The groove formed by the cover holding portion 221b opens toward the light emitting element 211 inside the frame 220 . The light emitting module 210 and the cover 230 are attached to the frame 220 by being inserted from the ends of the frame 220 in the longitudinal direction (X-axis direction). Further, the frame 220 is provided with a second cover holding portion 221c inside the cover holding portion 221b in the lateral direction (Y-axis direction).

(2) The first plate portion 221 and the second plate portion 223 can each share the load when a bending force is applied in the longitudinal direction (X-axis direction). For example, one against tensile forces and the other against compressive forces. In addition, the bending force includes bending due to a load, or a pulling load due to a spring or the like. (3) The column portion 222 opposes a force that tends to twist in the lateral direction (Y-axis direction), and rather than increasing its length in the vertical direction (Z-axis direction), By lengthening the width dimension in the axial direction, twisting can be made difficult. For example, the width dimension in the lateral direction (Y-axis direction) of the column portion 222 may be made thicker than the plate thickness of the first plate portion 221 or the plate thickness of the second plate portion 223 . In this way, the rigidity of the frame 220 can be obtained without forming the pillars 222 long in the vertical direction (Z-axis direction). Therefore, the frame 220 can be made thin.

In the lighting device 1, the frame 220 and the fixture main body 110 have the following relationship with respect to the length in the lateral direction (Y-axis direction) between the frame 220 and the main body opening 113 of the fixture main body 110. Here, the outer dimension of main body opening 113 is defined as distance LS1. The distance LS1 is the outside to outside dimension of the pair of side portions 112 . The inner dimension of body opening 113 is defined as distance LS2. The distance LS2 is the shortest dimension between the convex portions 114 facing each other. In the short-side direction (Y-axis direction) of the frame 220, the dimension of the first plate portion 221 in the short-side direction (Y-axis direction) is defined as length LS3. A dimension of the second plate portion 223 in the lateral direction (Y-axis direction) of the frame 220 is defined as a length LS4. Here, length LS3 of first plate portion 221 is greater than length LS4 of second plate portion 223 . Also, the length LS3 of the first plate portion 221 is greater than the distance LS1, which is the outer dimension of the main body opening 113 .

The distance between the end portion 251a2 of the hooking claw portion 251a and the end portion 251b1 of the hooking plate portion 251b should be such that the second plate portion 223 can be held between the hooking claw portion 251a and the hooking plate portion 251b. good. When attaching the spring 250, when the hooking claw portion 251a faces the end face of the frame 220, the spring 250 is attached to the frame 220 by making the distance between the end portion 251a2 and the end portion 251b1 larger than the thickness of the second plate portion 223. Easier to install. Further, when the hook plate portion 251b is opposed to the second plate portion 223 when attaching the spring 250, the distance between the end portion 251a2 and the end portion 251b1 is made substantially equal to the thickness of the second plate portion 223. , it becomes easier to attach the spring 250 to the frame 220 .

In the light source unit 200, the spring body portion 252 is a spring bottom portion 252b that faces the second plate portion 223 in the vertical direction (Z-axis direction), and both edges of the spring bottom portion 252b in the short direction (Y-axis direction). It has a spring claw portion 252a provided so as to protrude from. The spring claw portion 252a has a spring engaging portion 252c that engages with the convex portion 114 at the tip in the projecting direction.

A plurality of spring claw portions 252a are formed along the longitudinal direction (X-axis direction) of the spring body portion 252, which is the longitudinal direction (X-axis direction) of the light source unit 200.
