Definitions

  • the present invention relates to a reflector, in particular for a lighting device. comprising fixing means and at least half a mirror.
  • American patent 6,244,729 describes a lighting device comprising a tube elongated type fluorescent and also an elongated type reflector.
  • the shape of the reflector is variable.
  • an adjustment system is arranged at least one end of the reflector. This adjustment system makes it possible to modify the shape of the reflector, so as to keep a uniform radius of curvature, and therefore to obtain different light distributions according to the settings made.
  • Such a reflector has a complex structure because it requires, of a on the one hand, to be made of a flexible material, and on the other hand it includes a system adjustment made up of various parts, therefore particularly complicated, allowing to guide the light distribution.
  • obtaining a predetermined light distribution corresponding by example to a specific customer need, requires fine tuning which is not necessarily within reach of the client.
  • the object of the present invention is to propose a simpler structure reflector which meets the customer's wishes.
  • the reflector according to the invention is remarkable in that it comprises fixing means and at least one half-mirror so shaped as to be able to position itself in the fixing means and in delivering a first light distribution for a first mounting position of the at least half-mirror in the fixing means and at deliver a second light distribution for a second mounting position from to at least half a mirror in the fixing means corresponding to a reversal of said half-mirror.
  • the present invention therefore makes it possible to obtain the first light distribution desired for a first mounting position of the half-mirror in the means of fixation.
  • the customer can also easily obtain the second distribution desired light by dismantling the half-mirror, turning it over and making it set a second mounting position in the fixing means. So it is possible with a single reflector to have at least two different light distributions, which saves the customer from buying two reflectors, one dedicated to each distribution bright, to get the same result.
  • the present invention also relates to a luminaire comprising such a reflector and at least one lamp.
  • a luminaire comprising such a reflector and at least one lamp.
  • said luminaire is suitable for be equipped with one or two lamps
  • the customer can order a single product which he positions as he pleases. depending on the desired application and which it can possibly modify later by function of a new lighting distribution that he wishes to obtain from a set of possible light distributions.
  • This solution is therefore particularly simple and economic.
  • the present invention relates to a reflector comprising mirrors, said mirrors being inserted into the reflector.
  • These reflectors are in particular intended for lighting rail.
  • Mirrors are used to orient the luminous flux. In the mode of realization which follows, they are out of aluminum and have a form adapted to two Specific distributions desired when localized lighting of supermarket gondolas and equivalent businesses.
  • Mirrors can however have profiles and different materials, with different surface aspects such as matt, glossy or semi-glossy, in order to distribute the light according to a given application which can be, for example example, an intensive, extensive, asymmetrical or even light distribution bidirectional.
  • Figs. 1a and 1b represent a luminaire equipped with a lamp and a half-mirror as well as the light distribution corresponding to two different positions of the half-mirror.
  • the luminaire (1) comprises a reflector (10) of symmetrical structure with respect to an axis (2) and a neon-type lamp (20), for example, preferably placed on the axis of symmetry (2) at a height depending on the desired level of vertical lighting.
  • the reflector (10) comprises a half-mirror (11) which has hooks (12,13) at its ends and a central part having a predetermined radius of curvature in depending on the desired light distributions.
  • the hooks are an integral part of the half mirror. It is also possible, as an alternative, to provide a curved reflector with several hooks, the hooks here being parts reported, although such an achievement is more complex.
  • a fixing means comprises a housing (14,15) including a wall (16,17) forms a stop at an external part of a hook (12a, 13a).
  • some interior (12b) of a hook (12) is of dimension substantially greater than the part inner (13b) corresponding to the other hook.
  • the hooks (12,13) are of different dimensions to allow a relative position of the half-mirror (11) relative to the lamp (20) which is different for the two positions of mounting.
  • the shape of the half-mirror allows it to be fixed by simple wedging in housing by playing on its own elasticity.
  • the light distributions are of asymmetric type.
  • the reflector according to the invention has a system of tracking.
  • This marking system consists of marking the ends of the half-mirror to indicate to the installer the mounting position of the half-mirror according to a light distribution sought.
  • Fig. gives the example of a half mirror allowing to obtain a first light distribution (101) of asymmetrical type 20/25 °.
  • Fig. 1b shows the half mirror after its reversal allowing to obtain a second light distribution then (102) asymmetrical type 35/40 °.
  • the geometric shape of the half mirror and the position of the lamp in relation to the reflector are such that the level of vertical illumination maximum is greater than the maximum horizontal illumination level.
  • the luminaire must in addition to meeting mechanical scrolling specifications, the mechanical scrolling being the angle from which an observer no longer sees the lamp. In the embodiment preferred, this angle is at least 20 ° relative to the horizontal exit plane of the lamp.
  • the reflector can have more than two housings judiciously arranged so that the half-mirror can take several different positions and that the reflector can provide as many distributions as bright as possible configurations.
  • Figs. 2a and 2b represent a luminaire equipped with a lamp and two half-mirrors and the light distribution corresponding to two different symmetrical positions half-mirrors.
  • the lamp (20) is preferably placed on the axis of symmetry (2) of the reflector at a predetermined height depending on the desired level of lighting and taking into account the mechanical travel angle. Said lamp can also be located outside the axis of symmetry, while satisfying the lighting and angle conditions scrolling, so as to obtain a substantially different light distribution.
  • the luminaire is suitable for providing a first light distribution (201) of the asymmetrical double type 20/25 °.
  • the luminaire is capable of providing a second light distribution (202) of asymmetrical double type 35/40 ° after reversal of the two half-mirrors.
  • Figs. 3a and 3b represent a luminaire equipped with two lamps and a half-mirror and the light distribution corresponding to two different positions of the half-mirror.
  • the two lamps (20) are preferably placed symmetrically on one side and on the other side of the axis of symmetry (2) of the reflector at a predetermined height depending on the illumination level and mechanical scroll angle.
  • the luminaire is suitable for providing a first light distribution (301) of asymmetrical type 20/25 ° substantially different from the light distribution obtained with a lamp.
  • the luminaire is capable of providing a second light distribution (302) of asymmetrical type 35/40 ° after inversion of the half-mirror.
  • Figs. 4a and 4b represent a luminaire equipped with two lamps and two half mirrors and the light distribution corresponding to two different positions symmetrical half-mirrors.
  • the luminaire is suitable for provide a first light distribution (401) of the asymmetrical double type 20/25 ° significantly different from the light distribution obtained with a lamp.
  • the luminaire is capable of providing a second light distribution (402) of asymmetrical double type 35/40 ° after flipping the half-mirrors.
  • the luminaire can have more than two lamps, said lamps being arranged, for example, symmetrically with respect to the axis of symmetry (2) and at a predetermined distance from the ceiling of the reflector.
  • Such luminaire thus has a modular structure comprising a reflector provided with at least half a mirror and at least one lamp.
