Definitions
- An LED light emitting diode typically comprises a semiconductor component associated with a reflector within a transparent plastic casing, for example based on an epoxy resin.
- the front part of the molded envelope constitutes an internal lens or loupe, through which the light radiation produced by the light-emitting diode passes as a result of its connection to a power source.
- the viewing angle emitted by the diode depends on the shape of the reflector and the internal distance between the component and the lens. This viewing angle is constant for a type of LED, for example 20 °, and concentrates the majority of the useful luminous flux.
- an LED In order to vary the intensity of the luminous flux emitted by an LED, it is conventional to supply it via an adjustable current electronic circuit, for example a DC-DC converter, or a microcontroller connected to a battery. or batteries. This adjustment of the supply current causes a variation of the illumination power, but does not act on the radiation angle of the useful light beam.
- a conventional reflector of an incandescent lamp also does not allow to vary the viewing angle of an LED, because it acts in an area where the lamp emits very little light.
- the document US 6474837 relates to a light emitting diode lamp, according to the preamble of claim 1, and comprising a turntable in the form of a diaphragm pierced with orifices and provided with lenses placed in line with the orifices.
- the document WO 01/57431 discloses a lighting device consisting of an LED diode in front of which is permanently arranged a translational lens to change the relative distance from the diode.
- the object of the invention is to provide a portable LED diode lamp for easily adjusting the angle of the illuminating cone of said LED diode, to adjust the concentration of the luminous flux to obtain a wide range of illumination. short, or narrow and long-range lighting ..
- this object is achieved by the fact that the light-emitting diode of the emitter module is associated at the front with a magnifier housed in the orifice of the housing, and that the support of the lens is mounted on the outside of the housing. casing by coming in front of the magnifying glass in the active position.
- the lens holder can be mounted on a tilting or sliding plate, or on a rotary knob.
- a portable lighting device 10 comprises an emitter module ME equipped with at least one LED 11 for emitting a light beam, an element 12 for fixing and connecting said diode, and adjustment means of the light beam.
- the emitter module ME may consist of a single diode or a plurality of diodes 11 depending on the desired power rating.
- the element 12 of rectangular shape is secured to a base 13 equipped with a pair of slots 14 for receiving the fastening strap (not shown) of the headlamp.
- the adjustment means comprise an optical focusing device 15 that can be moved manually by the user in front of each LED.
- the illuminating cone can be obtained, either wide and short-range illumination, or narrow and long-range illumination.
- the optical focusing device 15 advantageously comprises two Fresnel lenses 16 integral with a movable support 17 movable between an inactive position located outside the light emission field of the diodes 11 ( Figures 1 to 3 ), and an active position ( Figures 4 and 5 ) in which the lenses 16 are traversed by said light beam by undergoing a deviation of the viewing angle.
- the lenses 16 are carried by a folding plate of the support 17, which is pivotally mounted about a horizontal axis 18 arranged at the upper part of the base 13.
- the support plate 17 bears on the upper edge of the element 12, leaving the diodes 11 visible.
- the user folds the plate of the mobile support 17 in front of the front face of the device. lighting 10 (arrow F1, figure 5 ), forcing the light beam emitted by the diodes 11 to pass through the lenses 16. This then results in a variation of the viewing angle and the illumination cone, to obtain either a wide illumination and short range, or a lighting narrow and long reach.
- the Figures 11A and 11B represent a Fresnel lens 11 used in the optical focusing device 15 of Figures 1 to 5 . It comprises a flat transparent substrate 19, made of polycarbonate or resin, in which are etched streaks 20 distributed in several concentric circular tracks 21 on one of the faces. The central portion 22 of the lens 11 is slightly curved and devoid of striations 20.
- the mobile support element 12 may comprise a plurality of lenses 16 corresponding to the same number of LEDs.
- the latter can be arranged in alignment, staggered, or angularly distributed at regular intervals around the periphery of the optical focusing device 15.
- the optical focusing device 15 instead of being mounted on a support 17 with folding plate, is fixed on a rotary knob 23 rotatable on a tip 24 of the support member 12 of circular shape.
- the two lenses 16 are diametrically opposed, and the angular adjustment stroke of the button 23 between the inactive position ( figure 8 ) and the active position ( figure 9 ) corresponds to a quarter turn in the case of two LEDs.
- the distance d between the end of the button 23 and a stop 25 of the support member 12 can be changed during an axial movement movement of the focusing device. This results in a continuous adjustment of the angle of the lighting cone of the light beam following the relative movement of the lens 16 relative to the diode 11.
- a lamp L1 is provided with an emitter module ME with a single diode 11 mounted at the rear on a radiator 31 and associated at the front with a magnifying glass 30.
- a module Semiconductor emitter ME is a standard commercial component, housed inside the housing 28 and intended to emit a light beam through a circular orifice 32 of the housing.
- a plate 26 carries the optical focusing device 15, which may be made of integrated optics, for example polycarbonate or glass. The plate 26 is pivotally mounted about a horizontal axis located below the emitter module ME.
- the plate 26 In the active position ( figure 12 ), the plate 26 is placed in front of the magnifying glass 30, and is traversed by the beam emitted by the diode 11. In the inactive position ( figures 13 and 14 ), the plate 26 is lowered by bearing on a flange 27 fixed housing 28 to be protected.
- a lamp L2 comprises a housing 28 of rectangular shape, having a housing compartment of the transmitter module ME, and a sliding drawer 33 integrating the optical focusing device 15.
- the drawer 33 is movable in translation in a vertical plane perpendicular to the light beam thanks to guide grooves 29 provided in the housing 28.
- the slide 33 is protected by a removable cap 34 which can be plugged into the housing 28.
- a gripping pin 35 moves the slide 33 between the retracted position ( figures 19 ) and the apparent position ( figure 18 ).
- the cap 34 may remain in place during this setting operation.
- the drawer 33 constitutes a one-piece piece having a predetermined focal length. This piece is easily interchangeable after removal of the cap 34.
