<P>PROBLEM TO BE SOLVED: To reduce the cost of a holder part. <P>SOLUTION: A display lamp 1 includes a display unit 2, a light irradiation part 3, a holder part 4, a case 5, and a cover 6. The display unit 2 is composed of a plate-like light guide 8 for radiating light made incident from an upper end surface 8b from the front surface of the light guide 8 and a display panel 7 arranged oppositely to the front surface of the light guide 8, provided with a pictogram 22 attached to the display panel and having light permeability. The light irradiation part 3 irradiates the inside of the light guide 8 with light from the upper end surface 8b. The holder part 4 is formed by a metal with high thermal conductivity, stores the light irradiation part 3 and adjacently opposes the light irradiation part 3 to the upper end surface 8b of the light guide 8. The case 5 is formed like a box shape of which the front is opened, and is configured so that a lighting device 15 for turning on a light source of the light irradiation part 3 is stored in it and the display unit 2 and the holder part 4 are attached to the front of the case 5. The cover 6 is attached to the case 5 so as to cover the holder part 4 exposed from the front of the case 5. <P>COPYRIGHT: (C)2010,JPO&INPIT |
