If configured so as to be possible, the light source unit includes a plurality of types of light source units of different types, each light source unit is set to a size that can be accommodated in the case, and a plurality of guide portions of the case are provided. If the light source unit is configured to be able to guide the seed, the light source unit including the light source corresponding to the environment of the installation place can be attached to the case, which is advantageous in terms of manufacturing cost.

  Hereinafter, embodiments of an indicator lamp according to the present invention will be described with reference to the drawings.

  The indicator lamp A is a ceiling direct attachment type or a ceiling suspension type, and is formed by suspending a light guide display plate 3 from a case 2 accommodating the light source units 1 and 1A.

  The light guide display plate 3 includes a light guide plate 31 and a pair of display plates 32 covering the surface of the light guide plate 31, and emits light when a light beam emitted from the light source enters from the upper end surface of the light guide plate 31. It is like that. Further, support bodies 33 having an inverted U-shaped cross section are attached to the left and right sides of the upper end portion of the light guide display panel 3.

The light source unit 1 uses a straight tube fluorescent lamp (for example, a T5 tube) 11 as a light source, and includes accessories (seamless slim appliances) including a ballast, a lighting starter, a socket 12, a support body 13 and the like. ) 14 is formed integrally. The light source unit 1A uses an LED 11A as a light source, and is integrally formed with an accessory 15A including a substrate 12A, a DC power supply unit 13A, a support 14A, and the like. A plurality of LEDs 11A are linearly mounted on the long substrate 12A along the length direction of the substrate 12A, and the substrate 12A is fixed to the support 14A.
The case 2 is formed in a horizontally long shape. Opening portions 21 are formed at both ends of the case 2 so that the light source units 1, 1 </ b> A and the light guide display plate 3 are opened in a horizontal direction. A second opening 22 for attaching the plate 3 is formed in communication with the opening 21. A plurality of steps of guide rails (an example of a guide portion) 23 are formed on the left and right inner side surfaces of the case 2 over the entire length of the case 2, and guide grooves 23 a are formed between the guide rails 23. An upward projecting wall 24 is formed below, and a second guide groove (an example of a second guide portion) 24 a is formed between the projecting wall 24 and the case 2 over the entire length of the case 2. An end cap 25 is detachably attached to the opening 21 of the case 2 with a screw 28. Reference numeral 26 in the figure denotes a screw hole formed around the opening 21 of the case 2, reference numeral 27 denotes an insertion hole for the screw 28 formed in the end cap 25, and reference numeral 29 denotes a ceiling direct attachment. It is a bracket for gripping a metal fitting (not shown) and screwing it.

  When the light source unit 1 is accommodated in the case 2, the light source unit 1 is inserted into the case 2 from the opening 21 of the case 2, and the support 13 of the light source unit 1 is mounted on the uppermost guide rail 23. It is placed and slid on the guide rail 23 to be accommodated in the case 2. In addition, you may set so that the support body of the light source unit 1 may be inserted in the guide groove 23a between the guide rails 23. FIG. In a state where the light source unit 1 is housed in the case 2, a power supply terminal (not shown) provided in the light source unit 1 is connected to a connection connector (not shown) of a commercial power supply (AC 100 V power supply) provided in the case 2. It has become.

  Further, when the light source unit 1A is accommodated in the case 2, the left and right ends of the support 14A of the light source unit 1A are fitted in the guide grooves 23a between the guide rails 23 and are slid on the guide rails 23 to slide inside the case 2. To house.

  The upper end of the light guide display plate 3 is inserted into the case 2 through the opening 21 and the second opening 22 of the case 2, and the support 33 of the light guide display plate 3 is fitted into the second guide groove 24a. The protruding wall 24 is slid to be accommodated in the case 2, and the upper end surface (light incident surface) of the light guide display panel 3 is opposed to the light source of the light source units 1 and 1A. When the support 33 is fitted into the second guide groove 24a, the support 33 sandwiches the protruding wall 24, so that the light guide display panel 3 is prevented from rolling and the case 2 is prevented from opening.

  After the light source unit 1 (or 1A) and the light guide display plate 3 are accommodated in the case 2, the opening 21 of the case 2 is closed with an end cap.

  The indicator lamp configured as described above can replace a plurality of types of light source units 1, 1 </ b> A with different types of light sources, and the light guide display plate 3 can be easily attached to and detached from the case 2.

It is a perspective view which shows the state which installed embodiment of the indicator lamp of this invention in the ceiling. (A) is a side view of the embodiment, (b) is a side view showing a state in which an end cap is attached. It is a front sectional view of the same embodiment.
