With reference to Figures 1-5, there is illustrated apparatus in accordance with the first embodiment of the invention. In this embodiment, there is provided a base 2 which is provided to receive a housing 4 although in another embodiment the base may be dispensed with and only the housing is provided.
In this embodiment shown, the housing and base are provided with electrical contact means not shown, which are located such that when the housing is located on the base, electrical contact is made between the housing and the base which allows the illumination of at least one light source located within the housing and contact with a power source provided within the base and/or housing. When the base 2 and housing 4 are separate as illustrated in Figure 2, a second light source in the housing is illuminated which causes light to be emitted from face 8 of the housing and hence allow the housing to be used as a torch.
When the housing 4 is placed in position on the base 2, the said light source shown in Figure 2 is extinguished and the light source within the housing 4 is illuminated by the creation of the electrical contact between the base and the housing. The illumination of this light source causes light to be projected as a night light through the walls 10 of the housing as illustrated in Figure 3. In an alternative arrangement the base 2 may be dispensed with and a switch to allow switching between the light source which is to be illuminated is provided for either manual movement by the user of the device or by placing the housing onto a surface which causes the switch condition to alter
In accordance with the invention the light source used to create the light effect and /or a further light source, can be used as a projection light which is emitted through the opening 14 of the housing 4 as shown in Figure 4. At the opening there is provided a transparent lens and focussing means 16, which allow the focusing of an image generated through the said face and beamed onto another display surface in the general direction 18, to be achieved.
The apparatus includes a projection member 20 which, in this embodiment is provided as a disc which, in Figure 4, is shown in a storage position on the base but which, when the apparatus is to be used in the projecting configuration, is in the embodiment shown, inserted into the aperture 22 in the housing 4. The projection member 20 is shown in more detail in Figure 5 and includes a series of projection images 24 provided along an annular path on the disc. Once the projection member is in position in the aperture 22 it can be rotated so as to selectively move a particular image 24 into the light path which is created by the illumination of the light source towards the external face. The light which is created passes through the image 24 and causes the same to be projected towards the opening 14 of the housing and hence onto a further surface such as a wall to be displayed.
The projection member can be rotated to move different images 24 into position and hence create a storyboard effect by the sequential movement of the projection member and hence generation of the displayed images. Typically, the images which are provided on the projection member 20, are linked to the images which are shown on other parts of the apparatus.
In many cases, it will still be desired to operate the apparatus as a night light rather than a projection means and therefore the projection member is provided with a blanking portion 26. When this blanking portion is selectively positioned in the light path, it prevents light from reaching the opening 14 and hence the light which is created by the illumination of the light source is solely emitted from the side walls of the housing so as to create the night light effect.
When a base 2 is provided as part of the apparatus, it is preferred that part of the underside 28 of the base and/or side wall of the base is provided at an angled arrangement such that when the apparatus is to be used in a projection configuration the base can be placed onto the angled portion 28 and thereby locate the housing in a preferred position so as to project the image onto a further surface. Figure 4 illustrates how the portion 28 can be placed on to the surface 31 such that the housing is placed at an angle other than vertical as is illustrated in Figure 4 where the longitudinal axis 33 of the apparatus is oriented at an angle A with respect to the vertical axis 35. This allows the image which is projected from the apparatus to be projected at a desired display angle onto a surface such as a wall or ceiling in the direction 18. It should be appreciated that in certain instances the apparatus does not include the base and the underside of the housing will be placed directly onto the support surface. In this case the surface of the housing which is to be used to contact the support surface can include at least one angled portion to thereby still allow the housing to be located at an angled configuration with respect to the support surface when that portion is placed into contact with the support surface.
Referring now to Figures 7a- g and 8a-c there are illustrated two embodiments of a lighting means 202 in accordance with one form of the invention. Figures 7a-g illustrate the outer form of the apparatus and Figures 8a-c illustrate a potential inner arrangement of the apparatus. The lighting means includes a base 204 from which a first light can be displayed from the transparent face (not shown) of the housing 208. The base is provided as part of a housing 208 which includes a further light source 209 which is positioned to illuminate the walls 210 of the housing and/or cavity 212. The cavity 212 is shown to have located therein a character model 214 which is viewable through the transparent walls of the portion 216 which is removably attached to the housing via attachment means 218.
The housing is also provided with an aperture 220 in the form of a slot which is provided to receive a projection member in the form of a disc 222 which can be similar to that shown under the reference numeral 20 in Figure 5. The projection member 222 is typically formed of a translucent material with a series of apertures 224 formed along circular path 226. The projection member is provided, when inserted into the aperture 220, to be rotatable with respect to the housing so as to allow a user to rotate the disc to bring one of the apertures to lie over the path of the light source 209 in the housing. Each of the apertures is typically provided with a transparent material or coloured material such that each aperture will give a different visual effect when positioned over the light source.
The base 204 of the apparatus includes, as shown in Figures 7a-g a number of angled portions 241 on the underside 243 and the base and hence apparatus can be placed with any of these portions 241 in contact with the support surface so as to provide the longitudinal axis of the housing at an angle other than perpendicular to the support surface. It is envisaged that this will be particularly useful when the apparatus is being used in a projection configuration.
In order to ensure that the light from the light source 209 reaches the cavity 212 and/or passes out of the housing to act as the projection light then an interior part 230 can be provided as shown in the embodiment of Figures 8a-c which restricts the light from passing to the side walls of the housing and instead channels the light from the light source in the direction of arrow 223 towards the cavity 212. Thus the part 230 effectively catches and channels light emitted from the light source 209 to the cavity to maximise the visual effect which is achieved.
When the apparatus is to be used as a projection means the character 214 and portion 216 are removed as shown in Figure 7a and the light can pass through the aperture 237 from the light source 209 and hence project the light and the image from the projection member externally of the housing in the direction of arrow 239.
The part 230 comprises a skirt portion 232 which fits over the wall of the housing to locate the part 230 with respect to the housing. The part also includes an inner guide cylinder 234 which has a free end which is located around the light source 209 and which extends towards the entry into the cavity 212 at which the skirt 232 is located. The skirt also includes a protrusion 236 which can be used to retain the cavity portion 216 thereon.
Turning now to Figure 6, there is illustrated a further embodiment of the invention in which there is once more provided apparatus comprising a base 102 and a housing 104. In this case, the housing includes a plurality of light sources 109, 111, which are illuminated in a similar manner to that described above with the other embodiments of the invention in order to allow the apparatus to be used as a torch when the source 111 is illuminated and as a night light when the source 109 is illuminated, although it should be appreciated that in another embodiment only one set of light sources may be provided to operate the night light configuration, with the torch operating configuration not being provided in that embodiment. In this case, the housing is at least partially formed by a portion 130 with transparent faces which can be selectively removed, so as to allow an article 132 located therein, to be removed from the housing 104 and used as a toy. The article or other articles can be selectively positioned in the housing and then enclosed by the replacement of the portion 130 into position. Thus, in this case, in the night light mode of operation, the article held within the housing is illuminated by the illumination of a light source when the housing is positioned on the base. In one embodiment the article can be provided with light transmission means and/or be transparent such that the same can be positioned over the light source and light passes into the article and then out therefrom so as to effectively "light up" the article.
It should be appreciated that although the embodiments illustrated herein, show the provision of the apparatus as a base and housing combination, that other embodiments of the apparatus may only include a housing and these may operate in a similar manner. In this embodiment, the change between configurations of operation, can be achieved by the provision of a switch on the housing which, can either be manually operated or alternatively, can be operated by the placement of the housing onto a surface.
