Title:
灯具
Document Type and Number:
Japanese Patent JP7149127
Kind Code:
B2
Abstract:
To prevent a lighting fixture function from being damaged and water from entering an aircraft while allowing water to enter a lighting fixture chamber of a lighting fixture mounted on an exterior panel of the aircraft.SOLUTION: A power supply cable 50 for supplying electric power to a light source is arranged extending from inside a lighting fixture chamber 12 to outside the lighting fixture chamber 12, and an insertion hole 20B into which the power supply cable 50 is inserted is formed in a peripheral wall part 20B of a housing 20. In addition, a bushing 54 which is elastic is mounted in the insertion hole 20Ba. Consequently, water pooled in the lighting fixture chamber 12 is prevented from flowing along the power supply cable 50 to enter up to an in-aircraft space, and thus a possibility that an adverse influence such as corrosion is exerted on a body-side structure member of the aircraft is eliminated. Further, a body support part 34 of a cover member has a drain path 34a formed to discharge water pooled in the lighting fixture chamber 12 to the space outside an exterior panel. Consequently, a lighting fixture function can be easily maintained.SELECTED DRAWING: Figure 7
