Definitions

  • the present invention relates to a lighting apparatus, and more particularly to a lighting apparatus wherein the lighting effects produced thereby differ depending upon the spatial orientation of the body of the apparatus.
  • the pattern or sequence of lighting effects obtained is either selected by the user using the controller or merely selected at random by the electrical controller in accordance with an instruction by the user to select random patterns.
  • the different lighting effects are produced merely by selecting the particular pattern desired using a selector switch provided on the electrical controller. It is not known in the art for any for any other form of user input to be used to select the desired lighting effect, and the use of a rotary or linear selector switch is the most common.
  • the present invention aims to provide a lighting apparatus which allows for a greater level of user interaction with the apparatus itself, in that the apparatus is capable of producing different lighting effects depending upon how the body of the apparatus is moved and handled by a user. More particularly, the present invention aims to provide a lighting apparatus which produces a different lighting effect depending upon the spatial orientation of a body of the apparatus, the spatial orientation being adaptable by a user. With such a mechanism, increased human interaction with the lighting apparatus can be achieved.

  • the lighting effect produced by the present invention changes to produce a different lighting effect than was previously being emitted.
  • This provides the advantage that interaction of the user with the light apparatus is increased, as the user is effectively rewarded with a different lighting effect depending upon the orientation in which he/she places the lighting apparatus.
  • the light emitting means comprises a plurality of light emitting diodes of different colours, which are preferably red, blue and green.
  • the light emitting diodes By using such light emitting diodes, and pulse width modulating the diodes, then almost any colour at almost any amplitude can be achieved when the light from each diode is combined in a diffuser.
  • the light emitter means is preferably disposed within a diffusing means to diffuse the light emitted therefrom.
  • the diffusing means comprises one or more moulded acrylic bulbs within which the light emitter means are at least partially encased. The use of moulded acrylic provides the required diffusion effect, without causing too much absorption of the light by the diffuser.
  • the means for receiving electrical power further comprise at least one re-chargeable battery; and socket means for receiving an electrical cable from an external power supply for supplying charge current to the battery.
  • a re-chargeable battery within the lighting apparatus means that the apparatus can be cordless, which further encourages user interaction with the apparatus. Furthermore, the apparatus then becomes portable and can be taken anywhere for use provided the battery is charged.
  • the controller means is a programmable logic circuit such as a PIC chip which is suitably programmed within a software programme to control the light emitting means to produce the lighting effects in response to the orientation of the body as detected by the orientation detector means.
  • a programmable logic circuit renders control of the light emitting means quite straightforward, as in recent years programmable logic circuits of the PIC type have become increasingly easy to programme.
  • use of a programmable logic circuit provides a further advantage that it is possible for the circuit to be programmed with several different lighting effect programmes, to produce different changes in lighting effects dependent on the same changes in orientation of the body, such that it then becomes possible to produce different versions of the lighting apparatus of the present invention on the same assembly line.
  • the particular version for any particular lighting apparatus can be selected on the production line by setting one or more jumps provided on the electrical circuit board to select the programme to be operated by the programmable logic circuit.
  • the outer body is made of glass and is further arranged to diffuse any light emitted from components contained in the body. The use of glass increases the weight of the apparatus, to enhance the feeling of the user that the apparatus is a solid and quality product.
