Claims

[Scope of claim for utility model registration] 1. In order to be installed on the indoor wall surface W or ceiling surface R,
A device body A having a substantially U-shaped cross section; a reflector holder C having a small diameter and substantially U-shaped cross section built-in and fixed to the bottom wall of the device body A; and a reflector holder C installed on the bottom wall of the holder C. In order to enlarge and project the light reflected by the reflective plate D onto the indoor wall surface W and ceiling surface R, A convex lens 33 is attached to the body wall of the device body A in a relationship facing the reflector D, and when the surface of the convex lens 33 receives the reflected light, a certain color light is transmitted through the surface of the convex lens 33. A lighting device characterized in that a multilayer vacuum-deposited film 34 that acts on photolysis is integrally applied to reflect different colored lights. 2. A plurality of convex lenses 33 that transmit different colored light through the multilayer vacuum-deposited film 34 are prepared, and each of the convex lenses 33 is clamped and fixed in advance by a pair of a lens holding cover 35 and a lens receiving cover 36. While forming a unit body E, the focal length adjustment screw 48 of the convex lens 33 is screwed into the spring holder 45 which is fixed and protrudes inward from the body wall of the main body A of the instrument, so that it can move forward and backward. By removably locking both covers 35 and 36 of the unit body E to the screw 48, the unit body E can be attached to the body wall of the instrument body A in a replaceable manner, and its attachment state can be changed to the adjustment screw 48. 2. The lighting device according to claim 1, wherein the lighting device is held elastically by a wound coil spring.
