  • the present invention relates to a lighting device, in particular to a remote controllable lighting device and to a luminaire comprising such a lighting device.
  • Lighting devices exist in many different forms and based on a variety of light sources.
  • the development of new types of light sources for lighting devices has increased the possibilities to achieve lighting devices providing light with predetermined characteristics, such as light color, light diffusion, color temperature, light intensity, color hue, and color value.
  • There exist different approaches to change the characteristics of a lighting device One approach is to configure the existing components of the lighting device, such as reflectors, light exit windows or light sources.
  • Another approach is to add further light altering components such as coatings or diffusion elements.
  • a further approach, which is becoming more common, is to add electronics to the lighting device for controlling the characteristics of the emitted light.
  • the lighting device may thus comprise a controller for controlling the light characteristics.
  • the controller may enable a remote control of the lighting device, such that a user may perform the control from a remote controller such as a smart phone. Further, a group of lighting devices, such as a group of spotlights, may be configured simultaneously.
  • the remote control feature provides many advantages such as that the light characteristics of a lighting device may be configured without the need for physical interaction with the lighting device. Such interaction may be cumbersome if the lighting device is provided in a ceiling or the like, and also if many lighting devices is to be configured. However, the remote controlling may also render the control more difficult by that it is difficult to see the actual change in the light of the lighting device as response to a control input. Lighting devices comprising e.g. LEDs provides a more or less unidirectional light which requires that the user looks directly into the light beam of the provided light when setting the light characteristics. Thus, there is a need for improvement with regards to remotely controllable lighting devices.
  • a further object is to provide a remote controllable lighting device which may with advantage be fitted into existing holders.
  • Yet another object is to provide a lighting device which is remote controllable in a more user- friendly manner.
  • a lighting device comprising a main light source, a remote controllable controller for controlling the light characteristics of the lighting device , a light directing element arranged to direct light from the main light source through a light exit of the lighting device and into a main beam, and an assist light arrangement adapted to provide light in a secondary direction outside of the main beam, whereby the lighting device is arranged to emit assist light for facilitating the remote control of the light characteristics of the lighting device.
  • the controller is arranged as a part of the lighting device, the lighting device needs to be larger than a conventional lighting device.
  • a portion of the lighting device protrudes from the conventional holder.
  • the controller is arranged separate from the lighting device housing, the lighting device housing is forced to protrude due to lack of space in the holder. In many cases this protruding portion is not appreciated by end users today, who rather prefer lamps to be as imperceptible as possible.
  • the immediate solution to this problem is to arrange the controller and any further components outside of the holder, e.g. behind the ceiling in the case of a ceiling mounted spotlight holder.
  • the protruding portion is utilized for emitting assist light for assisting the remote control of the lighting device.
  • the assist light creates a sparkle forming a decorative element of the lighting device and providing the lighting device with a unique look.
  • the controller may be arranged as a part of the lighting device, the construction requires less space and the lighting device including the controller may be manufactured and handled as a single unit thus simplifying both the manufacturing and installation of the lighting device.
  • an example of a scenario where the assist light is useful is when setting a light scene with multiple lighting devices. It is hard for the operator wirelessly remote controlling the lighting devices, by for example a handheld device such as a smart phone, to see which lighting device is commissioned. It is especially difficult when the operator is viewing some of the lighting devices from large off axis angles or even from the back. It is also hard to see the direct light output of an individual lighting device, thus rendering setting of e.g. color or intensity difficult and more elaborate since the operator need to move around to each lighting device to be controlled, and in fact counteracts the advantage of remote controlling.
  • the assist light the remote controlling is facilitated and may even be enabled from a farther distance than what is possible with conventional wirelessly remote controllable lighting devices. Moreover, even if the lighting device is directed such that the main beam is directed away from the operator, he may still see the light output that he is setting.

  • the component may be added to a conventional lighting device, by e.g. replacing an existing light exit window, for enabling the assist light feature.
  • the light redirecting member may be arranged to guide a portion of the light from nearby the light exit of the lighting device.
  • the light emitted from the main light source has been better mixed than farther upstream of the light path, i.e. nearer the main light source.
  • the assist light arrangement may comprise an additional light source.
  • the additional light sources may be arranged to emit light from designated areas of the lighting device. Such areas can be the whole lighting device housing, parts of the housing by means of transmissive windows, a front section of the housing that protrudes outside of a luminaire in which the lighting device is arranged or in a recessed ceiling situation, or through the light exit window.
