Abstract: A latching power switch for a light emitting diode (“LED”) flashlight is disclosed which includes a vessel comprising upper and lower components for receiving and containing a lithium cell battery, a means of using the anodic and cathodic leads from the LED, an aperture provided through the said vessel, and a switching mechanism comprising a rotating cam movable through the vessel aperture. The switching device comprises an on-off switch. The switch operates by rotating a biwire LED in which its leads are formed to surround a lithium coin cell power source. The LED wire leads pass through holes in an electrically nonconductive cam which has both a protuberance for operating the cam and a lobe for latching against a surface of the aperture through which it passes. The cam latches the wire leads against their proper corresponding coin cell surfaces thus activating the circuit and causing the illumination of the LED.

Abstract: A lighting device includes a reflector, and a lens attached to a front open portion of the reflector. Cantilever-type elastic legs are formed on those portions of the lens respectively opposed to engagement holes in the reflector, and extend in a direction of the circumference of the lens. Engagement projections, for engagement in respective engagement holes, are formed at respective distal end portions of the elastic legs. When the lens is formed into a thin design, the length of the elastic legs in the circumferential direction is not limited, and each elastic leg can have a length sufficient to enable it to be elastically deformed so as to fit the engagement projection into the engagement hole. Therefore, the engagement projection can be positively and easily engaged in the engagement hole. Even if one tried to forcibly engage the engagement projection in the engagement hole, the elastic leg will not break.

Abstract: A lighting apparatus which enables a shade to be easily attached, detached and rotated with a simple structure and an enhanced degree of freedom in design. Grooves 9,10 defining arc-shaped portions 15,16, respectively, are formed around an axis of a head 4, to which is mounted a fluorescent light bulb 7. A shade 8 which is formed with protrusions 17, 18 opposite to the grooves 9, 10 is mounted to the head 4 so as to cover the fluorescent light bulb 7. By pressing the protrusions 17, 18 of the shade 8 into the grooves 9, 10 of the head 4, the shade 8 can be very easily mounted to the head 4. By lifting up the shade 8 from the head 4, the shade 8 can be very easily removed from the head 4. In addition, the shade 8 can be rotated by allowing the protrusions 17, 18 formed on the shade 8 to slide along the arc-shaped portions 15, 16. As such shade 8 allows a simple integral structure, degree of freedom in designing a lighting apparatus can be enhanced.

Abstract: A bulb shield for use in an automotive headlamp assembly, and a method for making same. The bulb shield includes a cup portion and a portion which extends from the cup portion and is configured for mounting to a reflector of the automotive headlamp assembly or to another, proximate structure. When the bulb shield is mounted, the cup portion is preferably generally horizontally aligned with a headlamp bulb in the automotive headlamp assembly, thereby eliminating a “hot spot” which would otherwise be viewable when looking into the headlamp beam. Preferably, at least a portion of the cup portion of the bulb shield is electro-formed. Such a bulb shield is relatively inexpensive and easy to make, yet can withstand the high temperatures which are typically experienced in an automotive headlamp assembly. Additionally, such a bulb shield can be inexpensively provided, yet meet precision requirements.

Abstract: A line illuminating apparatus comprises a pair of irradiating units 12a, 12b of the same structure. The irradiating unit 12a. The light irradiating unit 12a includes a light source 14a, a first light guide 16a consisting of a large number of optical fibers, a light connector 18a, and three second light guides 20 (20a to 20c). The first light guide 16a permits the light emitted from the light source 14a to be incident as a slender rectangular light ray on the light connector 18a. The light emitted from the light connector 18a is divided by the three second light guides 20. Each light guide 20 is in the form of a thin plate, and the light emitting surfaces of the light guides 20a to 20f are arranged to define a imaginary semicylindrical plane surrounding the irradiating line L of work 28. The particular construction is effective for suppressing the loss of energy required for illumination. Also, the inspection is not adversely affected by the presence of, for example, an irregularity on the surface of the work.

Abstract: A method for furnishing a perceptor with apparently continuous illumination over an extended target area, in which at any instant only part of said area is illuminated, but every part thereof is intermittently and repeatedly illuminated by discontinuous flashes. With regard to any one part of said target area, the flashes are repeated at time intervals not less than the decay period of the response elicited in the perceptor. The method is performed by means of a device which comprises a beam-generating arrangement (1) that focuses a beam of radiation (5) upon a rotatably-mounted light-deflector (6), which is rotated under control at a suitably high speed by mechanical means (9, 10, 11 and 12) so as repeatedly to illuminate a target area (15) with a narrow flash to radiation (16).
