  FIG. 3 is a diagram for explaining a basic mounting relationship between the hood 1000 and the spotlight 2000. FIG. 3 shows the hood 1000 and the spotlight 2000 as a hollow cylindrical shape, and shows a cross section thereof. A hood 1000 shown in FIG. 3 is a hollow hood formed of a soft elastic material (soft elastic body) having translucency. The hood 1000 includes an insertion side hood end 100 at the end. The insertion side hood end portion 100 has a hollow shape with a predetermined length L, and the outer shape matches the inner shape of the irradiation port 200 of the spotlight 2000. The insertion side hood end portion 100 is inserted outside the hollow irradiation port 200 from the end of the irradiation port 200 over a predetermined length L. The insertion-side hood end portion 100 becomes gradually thicker as the thickness T goes in the insertion direction X. That is, as shown in FIG. 3, the thickness gradually increases from T1 to T2 in the insertion direction X.

  The end of the insertion side hood end portion 100 is located in the vicinity of the lens cover 220 of the spotlight 2000. Therefore, since the wall thickness gradually increases from T1 to T2, the light radiated from the LED and entering the insertion side hood end 100 where the thickness changes does not easily escape to the outside of the insertion side hood end 100. Therefore, the hood 1000 becomes easy to shine.

  FIG. 4 is a cross-sectional view for explaining an actual mounting relationship between the hood 1000 and the spotlight 2000. As shown in FIG. 4, the insertion side hood end portion 100 of the hood 1000 has a “dent 103” (insertion side fitting portion) over the entire circumference to be attached to the irradiation port 200, and a protrusion 105 that forms the recess 103. (Over the entire circumference) and the outer diameter side 106 of the insertion side hood end portion 100 sandwiches the irradiation port 200 of the spotlight 2000. By forming a space for the protrusion 202 (irradiation side protrusion) formed on the outer diameter side of the irradiation port 200 by the recess 103, even if the protrusion 202 is small, the structure is difficult to come off. As described above, the insertion-side hood end portion 100 is provided with the recess 103 that fits with the protrusion 202 when inserted inside the irradiation port 200, and thus is difficult to come off from the irradiation port 200.

  The hood 1000 is a soft elastic material such as silicon rubber. Hereinafter, description will be given assuming silicon rubber. Since the material of the hood 1000 is silicon rubber, the hood 1000 can be easily attached by being pushed into the irradiation port 200, and can be removed by pulling in the direction opposite to the attaching direction from the attached state. In addition to silicon rubber, natural rubber or synthetic rubber can be used as a material.

  The hood 1000 increases the hardness of the silicon, so that a strong elastic force is exerted even when a force is applied from the outside, thereby producing an effect that does not easily come off.

  A soft elastic hood 1000 such as silicon rubber is transmissive and diffuses light. Thereby, an instrument (spotlight 2000) and an instrument periphery can be made bright. Therefore, by using the hood 1000, an atmosphere (image) as if using a mirror-equipped halogen lamp can be produced even with a concentrating spotlight using an LED and a lens. Since the hood 1000 can be easily attached to and detached from the spotlight 2000 (appliance), the image of the equipment can be changed by attaching and removing the hood 1000 after the equipment is installed.

Embodiment 2. FIG.

On the outer diameter side surface of the insertion-side hood end portion 100, a protrusion 108 (hood-side protrusion) that fits into the groove 207 when inserted inside the irradiation port 200 is formed. As a result, even when a force is applied from the outside, the hood 1000 has a cylindrical shape, so that the force escapes to the left and right, so that it is difficult to come off the irradiation port 200.

  FIG. 6 shows a configuration in which a plurality of protrusions 108 are provided on the protrusions 108a, 108b, and 108c. By providing a plurality of protrusions, the force applied to the protrusions when a force is applied to the hood 1000 can be dispersed. In this way, a plurality of protrusions are formed on the outer diameter side surface of the hollow insertion-side hood end 100, thereby dispersing the force applied to the protrusions.

  FIG. 7 shows a configuration using screws 211. As shown in FIG. 7, a screw hole 209 is formed in the irradiation port 200, and a recess 110 into which the screw 211 is inserted is formed in the insertion side hood end portion 100. Thereby, the hood 1000 can be prevented from dropping by screwing.

  Thus, the hollow irradiation port 200 has a plurality of screws 211 (protruding portions) protruding from the outside to the inside at the end where the hood 1000 is inserted. The insertion-side hood end portion 100 includes a plurality of indentations 110 that fit into the screws 211 of the plurality of screws 211 when inserted into the irradiation port 200. Therefore, the screw 1000 can reliably prevent the hood 1000 from dropping.
