Detailed Description

The present invention is further described with reference to the following examples and figures, which are to be understood by those skilled in the art as being illustrative only and not limiting in any way.

Fig. 1 shows a perspective view of a globe lamp according to the present invention, which comprises a base 20 and a yin-yang globe consisting of a hemispherical shell 11 with a relatively good light transmission and a hemispherical shell 12 with a relatively poor or non-light transmission. When the light source in the yin-yang spherical lampshade is lightened, the visual lighting effect similar to half moon can be obtained; when the observation angle or the placing posture of the spherical lampshade on the base is changed, the visual lighting effect of the moon phase (such as the crescent) which is correspondingly changed can be obtained.

The cross-sectional views of fig. 2-8 show the specific structure of different embodiments of the luminaire according to the utility model, respectively.

The lamp shown in fig. 2 is composed of a globe 10 and a power supply base 20 as a whole, wherein a driving member in the form of a freely rolling luminous ball is provided in the globe 10.

The globe 10 is at least partially made of a light-transmissive material, such as the catadioptric globe shown in fig. 1, which provides the visual lighting of the lunar lamp, or a single light-transmissive material (e.g., the vase-shaped globe shown in fig. 7 and 8 or the conventional globe design shown in fig. 9 and 10). In addition, the surface, particularly the outer surface, of the lamp housing 10 may be a rough surface having an uneven spherical surface like a planet, moon, or asteroid. The lamp housing 10 may be a molded piece and/or a 3D printed piece.

The luminescent ball shown in fig. 2 has a transparent or translucent ball shell 30, in which a weight 33, a wirelessly powered receiving coil 31 arranged around the weight 33 and a light source 32 powered by the receiving coil 31 are also fixedly arranged. The weight ratio of the weight 33 is absolutely superior in the whole luminous ball, for example, it may be more than 60%, or even more than 90%. In addition, a wireless power supply transmitting coil 21 is correspondingly arranged on the base 20.

In the embodiment shown in fig. 2, due to the strong gravity of the weight 33, no matter what posture the globe 10 is placed on the base 20, the light-emitting ball therein will roll to the lowest gravity center position in the globe 10, so that the posture of the receiving coil 31 fixedly disposed around the weight 33 relative to the transmitting coil 21 in the base 20 can be always kept constant, i.e. the receiving coil 31 and the transmitting coil 21 can always be kept aligned. The transmitting coil 21 shown in fig. 2 is horizontally arranged on the base 20, and the receiving coil 31 in the light emitting ball at the lowest barycenter position is also horizontally arranged; when the globe 10 is placed or set at a central set position of the base 20 in an arbitrary posture, the relative postures (orientations and distances) of the receiver coil 31 and the transmitter coil 21 are kept substantially constant, i.e., they can always be aligned with each other in the vertical direction (up and down). When the base is externally connected with a power supply, the light source 32 can be effectively and wirelessly powered through the mutually aligned transmitting coil 21 and receiving coil 31.

Although not specifically shown, an electronic control element such as a circuit board may be disposed in the light emitting ball of fig. 2 to realize controllable power supply of the light source 32 by the receiving coil 31.

The embodiment of fig. 3 is similar to that of fig. 2, except that a magnetic member 34 is additionally provided in the light emitting ball and a magnetic member 22 is additionally provided in the base 20. At least one of the magnetic member 34 and the magnetic member 22 is a magnet, and the other is a magnet or iron, both of which are capable of generating magnetic attraction. By means of the magnetic action of the magnetic member, the position of the light emitting ball or the receiving coil 31 therein relative to the base 20 or the transmitting coil 21 therein can be adjusted more quickly and accurately. In this embodiment, the weight member 33 may be omitted and only the magnetic member 34 and the magnetic member 22 may be used to be engaged with each other.

In either the embodiment of fig. 2 or fig. 3, the arrangement or specific orientation of the light source 32 provided in the light emitting ball relative to the base 20 can also be automatically adjusted accordingly.

The embodiment shown in fig. 4 is similar to that of fig. 3, except that a rotatable support 23 is provided on the base 20, a magnetic member 22 is provided on top of the support 23, and the support 23 is driven to rotate horizontally by a motor 24 fixedly provided in the base 20. When the globe 10 is placed on the supporting member 23 of the base 20, due to the gravity of the weight 33 and/or the magnetic attraction between the magnetic member 34 and the magnetic member 22, when the vertical rotation output shaft of the motor 24 drives the supporting member 23 of the base 20 to rotate horizontally, the globe 10 can be driven to rotate to obtain the corresponding dynamic visual lighting effect.

The embodiment shown in fig. 5 is similar to that of fig. 4, except that a manual rotation member 25 is additionally provided on the base 20, and the support member 23 is provided on the rotation member 25, so that the respective tilting rotation of the rotation shaft of the motor 24 and the support member 23 driven thereby can be achieved by manually adjusting the rotational position of the rotation member 25 in the vertical plane. The embodiment of fig. 5 is particularly useful as a lighted globe in which the globe 10 may be tilted to a particular angle relative to the base 20.

The embodiment of fig. 6 is similar to that of fig. 2, except that instead of a spherical shell 30, a housing 30' in the form of a rollable tetrahedron is used for the luminary within the lampshade.

The embodiment shown in fig. 7 and 8 is similar to that of fig. 2, except that instead of a globe 10, a dome vase design is used for the globe 10'. As shown in fig. 7 and 8, the receiver coils therein and the transmitter coils in the base can always be kept in an aligned posture regardless of the posture of the lamp housing 10'. In this embodiment, the luminous ball can be very conveniently inserted through the opening of the vase or lampshade 10'.

The embodiment of fig. 9 and 10 is similar to that of fig. 3, but with the base 20 omitted and the outer diameter of the bulb 30 of the light emitting ball within the globe 10 increased to slightly less than the inner diameter of the globe 10. The spherical shell 30 of this embodiment is provided with a light-blocking circular plate 35 dividing the interior thereof into two parts, and the two sides thereof can be respectively provided with an independently controlled light source 32 and a rechargeable battery 36. A receiving coil 31 located below the light-blocking circular plate is used to supply power to a light source 32 and a rechargeable battery 36. As shown in fig. 10, the light-blocking circular plate 35 is disposed on the weight block 33, and a magnetic member 34 may be disposed below the weight block 33; this arrangement not only quickly positions the receiver coil 31 in the correct power-supplying attitude, but also orients the light-shielding circular plate 35 in the vertical position.

In the embodiment shown in fig. 9 and 10, the lampshade 10 does not need to adopt the design of the yin-yang globe lampshade shown in fig. 1, and only needs to adopt a normal light-transmitting lampshade, so that the visual lighting effect of the lunar phase lamp can be realized by means of the light-blocking circular plate 35 or the partition plate.
