Endplate 120-1 and endplate 120-2 are the same shape.
(Main body 110)
As shown in fig. 3 and 5, the main body 110 includes: a recess 111 formed by bending and accommodating the light source unit 200; left and right contact portions 112 formed at both ends of the recess 111 and contacting the cover-side device body contact portion 236 of the light source unit 200; inclined portions 113 each having an inclined surface formed at an end of each of the left and right contact portions 112; a rising portion 114 formed by bending from an end of the inclined portion 113; and a curled portion 115c formed by bending an end portion of the rising portion 114 in a curled shape. As shown in fig. 5, the concave portion 111 includes a concave portion top plate 111a and two concave portion side walls 111b, the concave portion top plate 111a is a ceiling on the opposite side of the opening side on which the light source unit 200 is mounted, and the two concave portion side walls 111b are side plates on both sides of the concave portion top plate 111 a. Although not shown in the drawings, the recess top plate 111a has a mounting portion (mounting hole) for mounting on a mounted portion such as a ceiling.
(end plate 120)
The end plate 120 has a shape that closes the end of the body 110, and is trapezoidal in the present embodiment. The end plate 120 is attached to an end portion of the body 110, and not only can improve the appearance of the device body 100, but also serves as a reinforcing member for maintaining the shape of the body 110.
(light source 200)
As shown in fig. 4, the light source unit 200 includes: an LED substrate 210 on which a plurality of LEDs are arranged, a frame 220 for fixing the LED substrate 210, and a translucent cover 230 for covering the LED substrate 210. The lighting fixture 1000 has a long shape, and the main body 110, the light source 200, the translucent cover 230, and the like also have a long shape. The light source unit 200 is attached to the device main body 100 in a state in which the LED substrate 210, the frame 220, and the translucent cover 230 are integrated (fig. 5).
(1) The LED substrate 210 includes a substrate 211 and a plurality of LEDs 212 mounted on the substrate 211. As shown in fig. 1(a), the LED substrate 210 has an elongated shape, and the LEDs 212 are linearly arranged in 1 or more rows along the elongated shape.
(2) The frame 220 is detachably engaged with a main body-side engaging portion (not shown) of the main body 110 by a frame-side engaging portion (not shown) of the frame 220. As shown in fig. 4, the frame 220 has an open top surface, has a cross-section of "コ", and is formed in a strip shape having the same length as the main body 110 shown in fig. 3 and the translucent cover 230 shown in fig. 2 (a). As shown in fig. 4, the frame 220 has: a frame-side flat portion 221, the frame-side flat portion 221 being an elongated rectangular flat plate on which the LED substrate 210 is mounted; side plates 222 forming respective sides of the frame-side flat portion 221; and a curled portion 222c formed by curling an end portion of each side plate 222.
(3) The translucent cover 230 is used for diffusing and transmitting light emitted from the LED 212 mounted on the LED substrate 210.
(translucent cover 230)
As shown in fig. 2(a) and 4, the translucent cover 230 has an arch-shaped cross-sectional shape.
As shown in fig. 4, the translucent cover 230 includes left and right mounting portions 231, left and right side portions 232, a curved surface portion 233 (cover portion), and left and right claw portions 234.
(1) Each of the mounting portions 231 presses the LED mounting surface of the LED substrate 210 with its end portion, thereby pressing the inner surface of the LED substrate 210 against the frame-side flat portion 221.
(2) The side portions 232 stand from the respective mounting portions 231.
In fig. 4 and 5, the left side 232 is referred to as the 1 st side 232, and the right side is referred to as the 2 nd side 232. The 1 st side portion 232 and the 2 nd side portion 232 are erected in a wall shape from both ends in the longitudinal direction of the curved surface portion 233.
(3) The curved surface portion 233 is formed in an arch shape formed by curved surfaces protruding outward in such a manner as to connect the respective side portions 232.
(4) The claw portion 234 stands on the wall in the direction opposite to the side portion 232, and is formed in the longitudinal direction of the entire translucent cover 230. The claw portion tip portion 234R, which is the tip of the claw portion 234, is bent into an R-shape and engaged with the curled portion 222c of the side plate 222.
(card hanging groove 232a)
As shown in fig. 4, the side portion 232 has an engaging groove 232a (concave portion), and the engaging groove 232a (concave portion) has a concave cross section that is smoothly recessed from the outside to the inside of the translucent cover 230. The engaging groove 232a is formed in the longitudinal direction of the entire translucent cover 230 (fig. 2a), and is therefore referred to as a "groove". The catching groove 232a of the 1 st side 232 is a 1 st side recess, and the catching groove 232a of the 2 nd side 232 is a 2 nd side recess. The 1 st side recess and the 2 nd side recess are in the shape of a groove.
The operator can easily remove the light source unit 200 from the device body 100 without slipping by hooking fingers into the hooking grooves 232a and gripping the side portions 232 on both sides. Further, when the corner 232a-1 having a sharp tip is formed on the outer shell portion of the translucent cover 230, the finger can more easily catch the catch groove 232a, and the light source unit 200 can be more easily removed from the device body 100.
Embodiment mode 2
Embodiment 2 is a modification of the side portion 232 of embodiment 1. In embodiment 2, the same structure as embodiment 1 is omitted, and only the characteristic portions of embodiment 2 will be described. Fig. 6 is a sectional view showing a cross section of the light source unit 200 according to embodiment 2. Fig. 7 is a sectional view showing a section of a lighting fixture 1000 according to embodiment 2. Fig. 6 and 7 correspond to fig. 4 and 5 of embodiment 1.
The side portion 232 of embodiment 1 has a catching groove 232a, and the catching groove 232a has a concave cross section that is smoothly recessed from the outside to the inside of the translucent cover 230. On the other hand, the side portion 232 of embodiment 2 has a protruding portion 232b, and the protruding portion 232b is formed to protrude in a convex shape in the outer direction of the translucent cover 230. The engaging projection 232b is formed throughout the longitudinal direction of the translucent cover 232, similarly to the engaging groove 232 a. In fig. 6 and 7, the left side 232 is referred to as the 1 st side 232, and the right side 232 is referred to as the 2 nd side 232. The engaging protrusion 232b of the 1 st side part 232 is a 1 st side protrusion, and the engaging protrusion 232b of the 2 nd side part 232 is a 2 nd side protrusion. The 1 st protrusion and the 2 nd protrusion are formed in a protruding shape.
As in the case of the engaging groove 232a, the operator can easily remove the light source unit 200 from the device body 100 by engaging the finger with the engaging projection 232b and gripping the side portions 232 provided on both sides of the translucent cover 230. Further, the engaging projection 232b may be formed such that the tip of the engaging projection 232b, which is a housing portion of the translucent cover 230, is formed into a sharp corner 232 b-1.
The engaging groove 232a of embodiment 1 and the engaging projection 232b of embodiment 2 are formed over the entire length of the translucent cover 230 in the longitudinal direction, but these are merely examples. The engaging groove 232a and the engaging projection 232b may not be formed over the entire length in the longitudinal direction, and may be formed partially in the longitudinal direction of the translucent cover 230.
In addition, although the hooking groove portion is described in embodiment 1 and the hooking protrusion portion is described in embodiment 2, both the hooking groove portion and the hooking protrusion portion may be formed.
