Detailed ways

The present invention will be further described below in conjunction with the embodiments and accompanying drawings. Those skilled in the art should understand that the embodiments and accompanying drawings are only for better understanding of the present invention, and are not used to make any limitation.

Referring to Fig. 1, it shows a specific structure of a lamp according to the present invention. In the structure shown in FIG. 1 , the main cover body 10 and the bottom cover 20 form a lampshade body that closes the spherical outer contour. The main cover body 10 and the bottom cover 20 can be connected together by bonding or other suitable means. The main cover 10 is made of a light-transmitting material such as a transparent or translucent material by molding or 3D printing, and its inner or outer surface can be a smooth surface or an uneven rough surface. The bottom cover 20 can be molded from light-transmitting or light-impermeable materials.

The inner side of the bottom cover 20 is provided with a structural support 21, on which a circular partition 30 is held (the lower part of the partition is provided with an installation interface corresponding to the outline of the support 21), and the diameter of the partition 30 is basically equal to the inner diameter of the spherical lampshade , thereby dividing the lampshade body into two separated spaces. The light transmittance of the partition 30 is lower than that of the main cover 10 , and is preferably made of an opaque material. One or both sides of the partition 30 are installed with independently controlled LED light sources 31 . In addition, a battery 32 for powering the light source 31 is optionally installed on the partition 30 . Battery 32 may be a primary or secondary battery. In addition, a power adapter 23 may also be provided on the bottom cover 20 to provide power for the light source 31 or the battery 32 . The power adapter 23 can be a power socket or a wireless power supply receiving coil.

Because the spherical lamp shown in Figure 1 is provided with a partition 30, when only the light source 31 on one side of the partition 30 is lighted, half of the spherical lampshade emits light, and the other half is dark. At this time, by changing its placement, different moon phase lighting effects from various crescents to full moons can be presented. In addition, when the light sources 31 on both sides of the partition 30 (only the light sources 31 on one side of the partition are shown in FIG. 1 ) are turned on, the effect of a panoramic spherical light can be presented.

FIG. 2 is an exploded schematic view of the spherical lamp shown in FIG. 1 . As shown in FIG. 1 and FIG. 2 , an orientation shaft 22 is fixed on the supporting member 21 , and a radial receiving groove 34 and fixing sleeves 33 located at both ends of the receiving groove 34 are arranged on the separator 30 . The receiving slot 34 on the bulkhead 30 and the sleeve 33 together form a shaft receiving mechanism for the orientation shaft 22, as discussed further below.

The main cover body 10 shown in FIG. 2 is one piece, and the partition plate 30 is put into it firstly during its manufacturing process. Because the diameter of the partition 30 is slightly smaller than the inner diameter of the main cover 10 or the spherical lampshade, the partition 30 can rotate freely therein after the main cover 10 is made. The orientation shaft 22 is installed on the support member 21 of the bottom cover 20, and is inserted into the receiving groove 34 and the sleeve 33 of the partition plate 30 from the opening reserved at the bottom of the main cover 10 to cooperate with the bottom cover 20, and thus The partition 30 is adjusted to a set position such as the vertical position shown. The partition 30 in the upright position minimizes the adverse lighting effects caused by the bottom cover 20 . After that, the bottom cover 20 is bonded and fixed to the main cover body 10 to form a closed spherical lamp cover body, as shown in FIG. 3 .

The structure of the spherical lamp shown in FIG. 4 is similar to that in FIG. 2 , wherein the support member 21 provided on the bottom cover 20 is replaced by the motor housing 23 , and the lower part of the partition 30 is provided with an installation interface 35 matching the outer contour of the motor housing 23 . The orientation shaft 22 protrudes upward from the motor casing 23 and is arranged coaxially with the motor rotation shaft 24 protruding downward. In this structure, the motor rotating shaft 24 can be placed on a supporting surface (not shown), so that the motor rotating shaft 24 is stationary relative to the supporting surface and the motor housing 23 rotates by relying on gravity when the motor is working, thereby driving the diaphragm The plate 30 rotates to form the lighting effect of changing moon phases.

FIG. 5 is a schematic diagram of a 3D printing manufacturing of the spherical lamp shown in FIG. 4 , where the main cover body 10 is first printed and manufactured by the 3D printing head 50 on the printing workbench 51 . When the horizontal layer printing reaches slightly more than half of the main cover 10, as shown in FIG. Next, adjust the partition plate 30 in place through the orientation shaft 22 and complete the bonding of the bottom cover 20 and the main cover body 10 to form a substantially closed spherical lamp cover body as described above with respect to FIGS. 2 and 3 .

FIG. 6 shows the spherical lampshade formed by the main cover 10 and the bottom cover 20 according to the above structure of the present invention placed on the support 40 . A power supply or charging device such as a wireless power supply transmitting coil (not shown) may also be provided on the support 40 to provide power for the spherical lamp. Although the bottom cover 20 is placed downwards, it can be placed in any orientation to obtain corresponding moon phase illumination. Of course, the optional support 40 can also be omitted and the spherical lampshade can be placed on any suitable supporting surface, as mentioned above.

Fig. 7 shows another modification of the spherical lamp according to the present invention, its structure is basically similar to that shown in Figs. A corresponding larger ring magnet 42 is disposed in the base 40 . The positioning shaft 25 passing downwards from the bottom cover 20 extends into the positioning slot 41 provided on the upper surface of the base 40 , and at this time the magnet 26 and the magnet 42 are coaxially arranged and the magnetic poles facing each other are opposite. Due to the interaction between the two, the spherical lamp can be quasi-suspended at a predetermined height above the base 40, and then through the auxiliary positioning function of the positioning shaft 25—the anti-horizontal displacement function, a quasi-suspension lamp can be realized. The working principle of this magnetic field structure can also be referred to the applicant's previous patents CN100544183C and CN105790641B, the entire contents of which are hereby incorporated by way of reference only.

In the structure shown in FIG. 7 , the positioning shaft 25 can also be omitted, and the spherical lamp can be used as a suspension body to cooperate with the suspension base (suspension device) to achieve its complete suspension effect. The structure and working principle of the suspension and the suspension base are well known to those skilled in the art, and are also disclosed in the above-mentioned patent of the applicant. When suspended, since the spherical lamp as a suspended body also has a degree of freedom of horizontal rotation, the partitions in it can also realize the ever-changing moon phase lighting effect.

In addition, the separator 30 in the above embodiments can also be replaced by a flexible separator such as a flexible light-shielding sheet, so that the assembly can be realized more simply and conveniently and the cost of the device can be further reduced, as described in the following embodiments.

The spherical lamp structure shown in Figures 8-11 is a modification of the embodiment shown in Figure 4 . As shown in Figures 8-11, a motor, a flexible partition 30', a light source (not specifically shown) and a battery (not shown) located on either side or both sides of the flexible partition 30' are fixedly arranged on the bottom cover 20. ) etc. to form the bottom cover assembly. In addition, the bottom cover 20 is also provided with a charging port 200 for charging the battery, and the battery can supply power for electric devices such as motors and light sources. The motor has a to-be-rotated portion or housing 23 to which the motor housing 23 is secured and a to-be-stationary portion or terminal output shaft 24 protruding slightly beyond the bottom cover 20 . The output shaft 24 is oriented along the diameter of the globe lamp or globe main enclosure 10 by means of the motor's gear reduction system 234 . The difference between this embodiment and the embodiment shown in Fig. 4 is mainly that a flexible partition 30' is used instead of the partition 30. The flexible partition 30' can be made, for example, from a light-impermeable plastic disc. The following briefly describes the assembly process of the spherical lamp of this embodiment according to FIGS. 8-11 .

First, the bottom cover assembly shown in Figure 8 is assembled, wherein the flexible partition 30' is in a fully extended state. Next, the bottom cover assembly shown in FIG. 8 is assembled into the spherical main cover body 10 formed by 3D printing in advance, wherein a circular installation opening 11 is left at the bottom of the main cover body 10 . As shown in Figure 9, the flexible partition 30' on the bottom cover assembly is folded into a cylindrical shape; then it is inserted into the main cover body 10 through the installation opening 11, as shown in Figure 10 . After the flexible partition 30' is fully inserted into the main cover body 10, it will be fully expanded again by means of elasticity, as shown in Figure 11, thereby dividing the inside of the main cover body 10 into two independent spaces. Finally, the bottom cover 20 is bonded and fixed to the installation opening of the main cover body 10 to form a complete spherical lamp structure. In this structure, it is also possible to place the motor output shaft 24 on a suitable support surface (not shown), so that the motor output shaft 24 is stationary relative to the support surface and the motor casing 23 rotates by relying on gravity when the motor is working. Thus, the partition 30' is driven to rotate to form a lighting effect of changing moon phases.

In the embodiment shown in FIGS. 8-11, the charging port 200 on the bottom cover 20 can also be omitted, and as described for the embodiment shown in FIG. The wireless power supply receiving coil is set on the base to cooperate with, for example, the wireless power supply transmitting coil set on the additional support to supply power to the electric devices therein. In this case, the overall appearance of the spherical light is more perfect.

Those skilled in the art can understand that: the lamp of the present invention is not limited to a spherical shape, and can also have a closed lampshade of any suitable shape; the baffle positioning adjustment device formed by the orientation shaft and the shaft receiving mechanism is not limited to the illustrated embodiment, Any suitable means enabling adjustment of the position of the bulkhead within the main enclosure is possible. In addition, as an alternative, the separator is not limited to a planar circular plate structure, and other hemispherical structures or other suitable special-shaped structures that limit the light emitting range may also be used. In addition, as another alternative, it is even possible to omit the inner partition and use a material with poor light transmission, such as an opaque material, to make a part of the spherical lampshade, such as half, or add an opaque hemispherical surface to the outside of the spherical lampshade. cover. These alternative ways can all realize the corresponding moon phase change lighting effect of the spherical lamp.
