Le document FR-A-2 793 676 décrit un dispositif d'éclairage comprenant un boítier dans lequel sont disposés une ampoule et des ensembles optiques. Chaque ensemble optique comprend un miroir et un hublot. Le miroir est adapté pour renvoyer un faisceau de lumière émis par l'ampoule vers le hublot, qui est adapté pour focaliser le faisceau sur un plan d'éclairage.Document FR-A-2 793 676 describes a device lighting comprising a housing in which are arranged a light bulb and optical assemblies.

However, these devices include a housing whose areas surrounding the portholes are opaque in order to guarantee homogeneous lighting. These opaque zones lead at a low luminous power and a little housing aesthetic.

La présente invention a pour but de pallier les inconvénients cités, et de proposer un ensemble qui permette une modification de la taille de la tache d'éclairage tout en ayant un bon rendement.

  • Figure 2 is a view of the section on the plane AA of Figure 1; and
  • Figure 3 is an enlarged perspective view of a moving optical assembly of the device of Figures 1 and 2.

La Figure 1 représente un dispositif d'éclairage selon l'invention désigné par la référence générale 2. Ce dispositif 2 est destiné à éclairer un champ d'éclairage 4, tel qu'un champ d'opération médicale défini par un plan d'éclairage P. A cet effet, le dispositif 2 est adapté pour créer une tache d'éclairage 6 dans le plan P.Figure 1 shows a lighting device according to the invention designated by the general reference 2. This device 2 is intended to illuminate a lighting field 4, such as a field of medical operation defined by a plan P. For this purpose, the device 2 is adapted to create a lighting spot 6 in the plane P.

Le dispositif 2 est muni d'un boítier 10 comprenant un carter 12 et d'une plaque de fermeture 14. Le carter 12 délimite une ouverture 16 dirigée vers le plan P. La plaque de fermeture 14 obture l'ouverture 16 et est entièrement transparente. Elle est fabriquée d'une seule pièce, par exemple en matière plastique. Le boítier 10 comprend quatre lobes 18 et présente, en vue de dessus, une forme symétrique générale de croix.The device 2 is provided with a housing 10 comprising a housing 12 and a closure plate 14. The housing 12 defines an opening 16 directed towards the plane P. The plate closing 14 closes the opening 16 and is fully transparent. It is made in one piece by example plastic. The housing 10 includes four lobes 18 and presents, in top view, a symmetrical shape general cross.

Dans le boítier 10 sont disposés deux groupes d'éclairage 20 et 22.In the housing 10 are arranged two groups lighting 20 and 22.

Chacun des groupes d'éclairage 20, 22 comprend une ampoule d'éclairage 24, 26 maintenue dans une fixation d'ampoule 28, 30 et quatre condenseurs 32, 34 connus en soi et disposés dans la partie centrale du boítier. Les condenseurs 32, 34 sont adaptés pour générer quatre faisceaux de lumière F1 et F2 dirigés de l'ampoule associée vers les lobes 18 et définissant des axes centraux C-C.Each of the lighting groups 20, 22 comprises a light bulb 24, 26 held in a fixture 28, 30 and four condensers 32, 34 known per se and arranged in the central part of the housing. The condensers 32, 34 are adapted to generate four F1 and F2 light beams directed from the associated light bulb to the lobes 18 and defining central axes C-C.

Chacun des groupes 20, 22 comprend par ailleurs deux ensembles optiques mobiles 36 et deux ensembles optiques fixes 38. Chacun de ces ensembles est disposé dans l'un des lobes 18 et est adapté pour renvoyer l'un des faisceaux F1, F2 vers le plan d'éclairage P.Each of groups 20, 22 also comprises two mobile optical assemblies 36 and two optical assemblies 38. Each of these sets is located in one of the lobes 18 and is adapted to return one of the beams F1, F2 to the lighting plan P.

Un ensemble optique mobile 36 est représenté sur la Figure 3. Cet ensemble 36 comprend un support de fixation 40, un miroir de renvoi 42, et un hublot de focalisation 44.A moving optical assembly 36 is shown on the Figure 3. This assembly 36 includes a mounting bracket 40, a reflecting mirror 42, and a focusing port 44.

Le support de fixation 40 est une ferrure en forme de U inversé fixée sur le carter 12 et constituée d'une âme 46 qui relie deux bras 48, 50. Chaque bras 48, 50 est muni d'un ergot 52, 54 mobile en rotation autour d'un axe X-X.The mounting bracket 40 is a shaped fitting inverted U fixed to the housing 12 and consisting of a core 46 which connects two arms 48, 50. Each arm 48, 50 is provided with a lug 52, 54 movable in rotation about an axis X-X.

Le miroir de renvoi 42 est un miroir plan, s'étendant suivant un plan de miroir M. Le miroir 42 est réfléchissant dans le domaine de la lumière visible et transparent dans le domaine infrarouge. Un traitement optique 56 connu en soi est disposé sur le miroir, du côté opposé au hublot (Figure 1). Ce traitement optique 56 sert à envoyer les rayons infrarouge vers le boítier 12, afin d'évacuer l'énergie des rayons infrarouge.The reflecting mirror 42 is a plane mirror, extending in a mirror plane M. The mirror 42 is reflecting in the field of visible light and transparent in the infrared range. A treatment optical 56 known per se is arranged on the mirror, on the side opposite to the porthole (Figure 1). This optical treatment 56 serves to send the infrared rays to the housing 12, so to evacuate energy from infrared rays.

Le hublot de focalisation 44 s'étend suivant un plan de hublot H qui définit un angle compris entre 40° et 50° avec le plan M. Les deux plans H et M se coupent suivant un axe d'intersection Y-Y. Le hublot 44 comprend un premier et un second dioptre disposés coaxialement l'un derrière l'autre dans le sens de marche des rayons des faisceaux F1. Le premier dioptre est adapté pour corriger les aberrations optiques et le second dioptre est adapté pour uniformiser l'éclairage du faisceau F1.The focusing port 44 extends along a plane port H which defines an angle between 40 ° and 50 ° with plane M. The two planes H and M intersect according to a Y-Y intersection axis. The porthole 44 comprises a first and a second dioptre arranged coaxially one behind the other in the direction of travel of the beams of F1 beams. The first diopter is adapted to correct the aberrations optical and the second diopter is adapted to standardize F1 beam illumination.

Le miroir 42 et le hublot 44 sont fixés l'un à l'autre par deux plaques de liaison 58, 60 de forme générale triangulaire, s'étendant perpendiculairement aux plans M et H. Chacune des plaques 58, 60 s'étend à une extrémité axiale du miroir 42 et du hublot 44. Les plaques de liaison 58,60 , le miroir 42 et le hublot 44 forment donc un prisme à section triangulaire dont le côté situé en face du miroir 42 et du hublot 44 est ouvert.The mirror 42 and the porthole 44 are fixed one to the other by two connecting plates 58, 60 of general shape triangular, extending perpendicular to the planes M and H. Each of the plates 58, 60 extends at one axial end the mirror 42 and the porthole 44. The connecting plates 58,60, the mirror 42 and the porthole 44 thus form a prism to triangular section whose side facing the mirror 42 and the porthole 44 is open.

La position radiale du miroir 42 et du hublot 44, par rapport à l'axe X-X, peut être réglée. A cet effet, une fente rectiligne 62 est ménagée dans chaque plaque 58, 60. L'ergot 52, 54 associé traverse la fente 62 et est immobilisé dans la fente par des moyens d'immobilisation, tel qu'un écrou 64. The radial position of the mirror 42 and the porthole 44, relative to the X-X axis, can be set. For this purpose, a straight slot 62 is formed in each plate 58, 60. The associated pin 52, 54 passes through the slot 62 and is immobilized in the slot by means of immobilization, such as a nut 64.

Ainsi, les plaques 58, 60, le miroir 42 et le hublot 44 sont articulés aux bras 48, 50 de la ferrure autour de l'axe de rotation X-X par l'intermédiaire des ergots 52, 54.Thus, the plates 58, 60, the mirror 42 and the porthole 44 are articulated to the arms 48, 50 of the fitting around the axis of rotation X-X via the lugs 52, 54.

L'axe X-X s'étend parallèlement aux plans H et M, et est décalé de ces plans. De plus, l'axe X-X coupe l'axe central C-C du faisceau F1, F2 associé.The X-X axis extends parallel to the planes H and M, and is shifted from these plans. In addition, the X-X axis intersects the axis central C-C of the beam F1, F2 associated.

L'ensemble 36 comprend en outre une bielle 66 qui est fixée sur la plaque 60. La bielle 66 comprend une ouverture 68 dans laquelle s'engage un doigt d'entraínement non représenté qui est relié à des moyens d'entraínement de la bielle 66, tels qu'un moto-réducteur non représenté. Ainsi, le miroir 42 et le hublot 44 peuvent être déplacés angulairement de manière synchrone et d'un seul bloc autour de l'axe X-X en vue d'une modification de la taille de la tache d'éclairage 6.The assembly 36 further comprises a connecting rod 66 which is fixed on the plate 60. The connecting rod 66 comprises a opening 68 in which engages a training finger not shown which is connected to drive means of the connecting rod 66, such as a geared motor not shown. Thus, the mirror 42 and the porthole 44 can be moved angularly synchronously and in one block around of the X-X axis to change the size of the lighting spot 6.

Chaque ensemble optique fixe 38 comprend un miroir de renvoi 42 et un hublot de focalisation analogues aux miroir 42 et hublot 44 précités. Toutefois, ces miroir 42 et hublot 44 sont fixés au carter 12 et leurs positions ne sont pas modifiables par rapport au boítier 10.Each fixed optical assembly 38 includes a mirror 42 and a focus port similar to the mirror 42 and porthole 44 above. However, these mirror 42 and port 44 are attached to the housing 12 and their positions are not not modifiable compared to housing 10.

Le dispositif d'éclairage selon l'invention est assemblé et fonctionne de la façon suivante.The lighting device according to the invention is assembled and works as follows.

Tout d'abord, le support 40 est fixé dans le boítier 10. Puis la position du miroir 42 et du hublot 44 par rapport à l'ampoule 24 est préréglée par une modification de la position des plaques 58, 60 par rapport aux ergots 52, 54.First, the support 40 is fixed in the housing 10. Then the position of the mirror 42 and the porthole 44 by compared to bulb 24 is pre-set by a modification of the position of the plates 58, 60 with respect to the lugs 52, 54.

Lors d'un éclairage du champ d'opération 4, la taille de la tache d'éclairage 6 peut être réglée par un basculement des miroirs 42 et des hublots 44 des ensembles mobiles 36 autour de l'axe X-X.During a lighting operation field 4, the size of the lighting spot 6 can be set by a tilting mirrors 42 and portholes 44 of the assemblies movable 36 about the X-X axis.

Le fait de prévoir des ensembles mobiles 36 et fixes 38 dans le même boítier 10 conduit à un dispositif d'éclairage qui permet une variation de la taille de la tache d'éclairage 6, tout en étant économique.Providing 36 and fixed mobile assemblies 38 in the same housing 10 leads to a device lighting that allows a variation in the size of the lighting spot 6, while being economical.

De plus, les ensembles d'éclairage fixes 38 assurent un éclairage minimum au centre de la tache 6.In addition, fixed lighting assemblies 38 provide minimum illumination in the center of the stain 6.

De façon générale, il est préférable que la moitié des ensembles optiques soit constituée d'ensembles fixes 38 tandis que l'autre moitié soit constituée d'ensembles mobiles 36. De même, il est préférable que la moitié des ensembles optiques associés à une ampoule soit constitué d'ensembles mobiles 36, tandis que l'autre moitié des ensembles optiques soit constitué des ensembles fixes 38.In general, it is preferable that half optical assemblies consist of fixed assemblies 38 while the other half consists of sets Likewise, it is preferable that half of the optical assemblies associated with a bulb is constituted of mobile sets 36, while the other half of optical assemblies consists of fixed assemblies 38.

Grâce au fait que le miroir 42 et le hublot 44 des ensembles mobiles 36 sont fixes l'un par rapport à l'autre, une modification de la position du miroir 42 par rapport à l'ampoule 24 ne modifie pas la position du miroir 42 par rapport au hublot 44. En conséquence, l'aberration du faisceau de lumière F1 qui sort du hublot 44 est toujours corrigée de la même manière, et il n'est pas nécessaire de masquer partiellement ce faisceau F1. Ceci conduit à un bon rendement énergétique du dispositif. De plus, la plaque de fermeture 14 peut donc être complètement transparente et esthétique.Thanks to the fact that the mirror 42 and the porthole 44 of the mobile assemblies 36 are fixed relative to one another, a modification of the position of the mirror 42 with respect to the bulb 24 does not change the position of the mirror 42 by to the porthole. 44. Consequently, the aberration of the F1 beam of light coming out of porthole 44 is still corrected in the same way, and it is not necessary to partially hide this F1 beam. This leads to a good energy efficiency of the device. In addition, the plaque closure 14 can be completely transparent and aesthetic.

En variante, tous les ensembles optiques mobiles 36 sont associés à l'une des ampoules 24, 26, tandis que tous les ensembles optiques fixes 38 sont associés à une autre ampoule 26, 24.As a variant, all the mobile optical assemblies 36 are associated with one of the bulbs 24, 26, while all the fixed optical assemblies 38 are associated with another bulb 26, 24.
