Definitions

  • the present invention relates to an adjustable lighting device and relates particularly, though not exclusively, to an adjustable lighting device that employs an LED array as the light source.
  • GaAs gallium arsenide
  • LEDs are now being used in many applications, for example, to replace the traditional halogen globes used for internal lighting, such as in downlights and other decorative internal lighting fixtures.
  • the present invention was developed with a view to providing an adjustable lighting device which employs LEDs as the light source, which may typically be used as an internal decorative light fixture.
  • LEDs as the light source
  • any suitable light source may be employed and the invention is not limited to the use of LEDs.
  • an adjustable lighting device comprising: a light source; a luminaire body on which the light source is supported, the light source facing backwards towards a wall, ceiling or other surface on which the device is mounted; an adjustable support arm mechanically coupled to the luminaire body for attaching the lighting device to the wall, ceiling or other surface, the mechanical coupling permitting pivoting movement of the luminaire body about at least one axis wherein, in use, the direction in which light is directed from the light source to the wall, ceiling or other surface may be varied.
  • the mechanical coupling is a ball and socket joint which permits pivoting movement of the luminaire body about multiple axes.
  • the lighting device further comprises a diffuser mounted in front of the light source, the diffuser distributing the light from the light source more uniformly onto the wall, ceiling or other surface.
  • the light source is an LED array.
  • the LEDs are arranged in a circular array on a rear surface of the luminaire body.
  • the diffuser is also of circular configuration.
  • each LED in the array is fitted with a micro-lens on its front surface.
  • the luminaire body comprises a mounting plate hich forms a heat sink for the LED array, the mounting plate being provided with a plurality of cooling fins on its rear face.
  • the lighting device further comprises an opaque grip panel which is attached to the rear of the luminaire body.
  • the grip is attached to the rear of the luminaire body.
  • RO/AU panel is of rectangular configuration (a square). However it will be appreciated that the grip panel could be of any desired shape or configuration. In use, the grip panel can be gripped on each side to adjust the angle of the lighting device relative to the wall, ceiling or other surface on which it is mounted.
  • the adjustable support arm comprises a first elongate member which is mechanically coupled at one end to the luminaire body, and which is slidably received in one end of a second hollow elongate member, the second elongate member being attachable at the other end to the wall, ceiling or other surface whereby, in use, the support arm is telescopically adjustable by sliding the first member into or out of the second member.
  • Figure 1 (a) is a rear top isometric view of a first embodiment of a lighting device according to the present invention
  • Figures 1 (b), (c) and (d) are a plan elevation, front elevation and side elevation respectively of the lighting device of Figure 1 (a);
  • Figure 2 is a rear elevation of the lighting device of Figure 1 (a);
  • Figure 3 is a section view through the line A-A in Figure 2 of the lighting device
  • Figure 4 is a side elevation of the lighting device of Figure 1 (a) illustrating adjustment of the beam, spread;
  • Figure 5 is a rear elevation of the lighting device of Figure 1 (a) illustrating adjustment of the light direction;
  • Figures 6 (a) and (b) are a side elevation and plan elevation respectively of the lighting device of Figure 1 (a) further illustrating adjustment of the light direction.
  • a preferred embodiment of an adjustable lighting device 10 in accordance with the invention comprises a light source 12 and a luminaire body 14 on which the light source 12 is supported.
  • the light source 12 (see Figure 3) is mounted so that it faces backwards towards a wall, ceiling or other surface on which the device is mounted (not shown).
  • An adjustable support arm 16 is mechanically coupled to the luminaire body 14 for attaching the lighting device 10 to the wall, ceiling or other surface.
  • the mechanical coupling of the adjustable support arm 16 to the luminaire body 14 permits pivoting movement of the luminaire body about at least one axis. In use, the direction in which light is directed from the light source 12 to the wall, ceiling or other surface may be varied.
  • the lighting device further comprises a diffuser 20 mounted in front of the light source 12.
  • the diffuser 20 distributes the light from the light source 12 more uniformly onto the wall, ceiling or other surface.
  • the light source 12 is an array of LEDs 22 (see Figure 3). The LEDs 22 are arranged in a circular array on a rear surface of the luminaire
  • each LED 22 in the array is fitted with a micro-lens on its front surface.
  • any suitable light source may be used, and the invention is not limited to the use LEDs. However LEDs are particularly advantageous because of their compact size and improved efficiency (high brightness and low power consumption).
  • the luminaire body 14 comprises a mounting plate 24 on which a printed circuit board (PCB) 26 for the LEDs 22 is mounted.
  • the mounting plate 24 also forms a heat sink for the LED array, and is provided with a plurality of cooling ⁇ fins 28 on its front face, as can be seen most clearly in Figures 1 (b) and 6(b).
  • the ball of the ball and socket joint 18 is received in a recess formed in the centre of the mounting plate 24, as can be seen most clearly in Figure 3.
  • the diffuser 20 is fastened to the mounting plate 24 by two M2 fasteners (not visible in the drawings). This clamps the PCB 26 to the mounting plate 24 and assembles the ball and socket joint 18.
  • the lighting device further comprises an opaque grip panel 30 which is attached to the rear of the luminaire body.
  • the grip panel 30 is formed with a hollow section 32 on each of two opposite sides which may be used as hand grips.
  • the grip panel 30 is of rectangular configuration (a square).
  • the grip panel 30 may be of any desired shape or configuration. In use, the grip panel 30 can be gripped with two hands on each side to adjust the angle of the lighting device 10 relative to the wall, ceiling or other surface on which it is mounted.
  • the adjustable support arm 16 comprises a first elongate member 36 which is mechanically coupled at one end to the luminaire body 14, as can be seen most clearly in Figure 3.
  • the first elongate member 36 is slidably received through one end of a second hollow elongate member 38.
  • the second elongate member 38 is attachable at its other end to the wall, ceiling or other surface on which the device 10 is mounted.
  • Both elongate members 36 and 38 are typically cylindrical in shape.
  • the first elongate member 36 is formed with the ball of the ball and socket joint 18 on its one end.
  • the support arm 16 is teiescopically adjustable by
  • the LED array provides a low-power, high brightness light source, which may also be dimmable if desired.
  • the mechanical coupling of the adjustable arm to the luminaire body may be via any suitable coupling, for example, a simple hinge; although a ball and socket joint is preferably because of its versatility. Therefore, it will be appreciated that the scope of the invention is not limited to the specific embodiments described.

Abstract

L'invention, qui concerne un dispositif d'éclairage indirect pouvant être réglé de façon à orienter une source de lumière vers des surfaces adjacentes, concerne également des moyens de montage. Le dispositif comprend un bras support réglable, un corps de luminaire, et une source de lumière, le corps de luminaire étant mécaniquement couplé au bras support réglable, fixant ainsi le dispositif d'éclairage à la surface adjacente. La source de lumière, qui est supportée par le corps de luminaire de façon à être orientée vers l'arrière en direction de la surface de montage, peut être dirigée au moyen du bras support réglable permettant un mouvement de pivotement du corps de luminaire autour d'au moins un axe.
