Definitions

  • the invention relates to a portable electric lamp comprising a lighting module, a switch for the ignition control of the light source, means for modifying the light beam emitted by the light source through a window of the housing, and comprising optical transmission means mounted to tilt about an axis of articulation integral with the housing, allowing a limited pivoting movement between an inactive position spaced from the light source, and an active position located opposite the light source.
  • an emergency lamp is described in US-A-5490050, wherein the illumination module comprises a flash bulb or xenon which emits a visible white light.
  • Interchangeable blue and infrared filters are pivotally mounted on a body to filter certain wavelengths of the light emitted by the bulb.
  • the body is projecting on the bulb, the assembly having a large longitudinal dimension.
  • Colored glass can also be an accessory that can be attached to the front.
  • Such an accessory is not integrated with the lamp housing, and can be lost or forgotten during use. Its fixation requires action manual mounting, for example screwing, fitting or snapping, which can be difficult to implement according to the conditions of use. For the return to the initial state of illumination of white light, it is necessary to dismount the colored window, and to put it in a precise place easily recognizable thereafter for a new change of state of illumination.
  • Document DE 2026691 relates to a non-portable lamp, having two bulbs arranged in reverse, emitting a white light capable of passing through one or two screens of yellow and purple color.
  • the set of bulbs and screens is arranged inside an envelope closed by a window.
  • US-A-3843878 relates to a flash lamp for a camera, equipped with a retractable filter, can be removed from its housing, and folded in front of the flash tube.
  • the pivot axis of the filter is placed in the opening of the housing, and in front of the tube located at the bottom of the reflector.
  • the object of the invention is to provide a portable electric light-emitting diode lamp allowing the user to easily change the color of the lighting beam.
  • Another object of the invention is to provide a portable electric light-emitting diode lamp allowing the user to vary the viewing angle of the illumination beam.
  • the lamp according to the invention is characterized in that the light source is formed by electroluminescent diodes, and that the hinge axis extends parallel to the alignment direction of at least two diodes, said axis being placed indented and under the diodes.
  • the optical transmission means may be formed by a color filter or a suitable lens.
  • the front face of the housing preferably comprises a flange serving to support the filter or the lens in the inactive position.
  • the filter or the lens preferably has an L shape, having a gripping finger at the top, and a cylindrical protuberance at the bottom constituting said hinge axis.
  • a portable electric lamp 10 in particular a headlamp, comprises a casing 11 made of molded plastic, enclosing a light-emitting module 12 with LEDs 13, a power source (not shown) with batteries or accumulators, and a switch 14 for the ignition control of the diodes 13.
  • the housing 11 is composed of a posterior bottom, an anterior casing 16, and an intermediate wall 17, which divides the inside of the casing 11 into a first compartment 18 housing the diodes 13, and a second compartment 19 for the power source.
  • the assembly of the bottom 15 to the casing 16 is made by snapping or by any other fastening means.
  • the front face of the envelope 16 is provided with a front window 20 permitting the crossing of the light beam emitted by the diodes 13, and a flange 21 protruding outwardly from the front face.
  • the lighting module 12 is provided by way of example of three diodes 13 aligned horizontally in the window 20 of the first compartment 18. It is of course possible to modify the arrangement and the number of diodes 13.
  • Optical transmission means comprise a colored filter 22 mounted to tilt about a horizontal axis of articulation 23 to allow limited pivoting movement between an inactive position (FIGS. 1 and 3) and an active position (FIGS. 2 and 4). ).
  • the lower end of the filter 22 is provided with a cylindrical protuberance constituting said axis of articulation 23 guided in rotation in bearings of the intermediate wall 17.
  • the upper edge of the filter 22 is equipped with a gripping finger 24 facilitating the pivotal movement between the inactive position to the active position and vice versa.
  • the horizontal hinge axis 23 of the filter 22 extends substantially parallel to the alignment axis of at least two diodes 13, and is advantageously set back and under the diodes 13.
  • the filter 22 is made of transparent plastic material, containing pigmentation agents corresponding to the desired coloration.
  • the filter 22 bears on the rim 21 of the envelope 16, and the diodes 13 emit a white light beam when the switch 14 is in the closed state.
  • the first compartment 18 is open, because there is no window in front of the diodes 13.
  • the filter 22 By pivoting the filter 22 from the inactive position lowered to the active position raised ( Figures 2 and 4), the first compartment 18 is closed following the engagement of the filter 22 against the edges of the window 20.
  • the positioning recessed of the hinge pin 23 makes it possible to place the filter 22 at a small distance from the diodes 13, and to integrate it completely into the window 20 without protruding from the front face of the envelope 16.
  • the coloring of the beam Illumination is changed after crossing the filter 22. In the example of a red filter 22, the beam turns red.
  • the optical transmission means may be formed by a lens, for example a Fresnel lens, intended to vary the viewing angle depending on whether it is in the active position or in the inactive position.
  • a lens for example a Fresnel lens
