Detailed Description

The present invention is further described with reference to the following examples and accompanying drawings, which are included to provide a further understanding of the invention, and are not intended to limit the scope of the invention.

Referring to fig. 1, a specific structure of a lamp according to the present invention is shown. In the structure shown in fig. 1, the main housing 10 and the bottom cover 20 form a housing with a closed spherical outer contour. The main housing 10 and the bottom cover 20 may be coupled together by a suitable means such as bonding. The main housing 10 is made of a light-transmitting material, such as a transparent or translucent material, by molding or 3D printing, and the inner surface or the outer surface thereof may be a smooth surface or an uneven rough surface. The bottom cover 20 may be molded from a light transmissive or opaque material.

The bottom cover 20 is provided on the inside with a structural support 21 on which a circular partition 30 is held (the lower part of the partition is provided with a mounting interface corresponding to the contour of the support 21), the diameter of the partition 30 being substantially equal to the inner diameter of the spherical cover body, thereby dividing the interior of the cover body into two separate spaces. The partition 30 has a light transmittance smaller than that of the main housing 10 and is preferably made of a light-impermeable material. An independently controlled LED light source 31 is mounted on one or both sides of the barrier 30. In addition, a battery 32 for supplying power to the light source 31 is optionally mounted on the spacer 30. The battery 32 may be a primary or secondary battery. In addition, a power adapter 23 may be provided on the bottom cover 20 to supply power to the light source 31 or the battery 32. The power adapter 23 may be a power jack or a wirelessly powered receiving coil.

Since the globe of fig. 1 is provided with the partition 30, when only the light source 31 on one side of the partition 30 is lighted, half of the globe body emits light and the other half is dark. At this time, by changing the placing position, different moon phase lighting effects from various crescents to full moon can be presented. In addition, when the light sources 31 on both sides of the partition 30 (fig. 1 only shows the light source 31 on one side of the partition) are turned on, the effect of the panoramic ball lamp can be displayed.

Fig. 2 is an exploded view of the globe lamp shown in fig. 1. As shown in fig. 1 and 2, the support member 21 is further fixed with a directional shaft 22, and the partition plate 30 is further provided with a radial receiving groove 34 and fixing sleeves 33 at both ends of the receiving groove 34. The receiving slot 34 in the diaphragm 30 and the sleeve 33 together constitute a shaft receiving mechanism for orienting the shaft 22, as discussed further below.

The main housing 10 shown in FIG. 2 is a unitary piece that is manufactured by first inserting the diaphragm 30 therein. Since the diameter of the spacer 30 is slightly smaller than the inner diameter of the main housing 10 or the spherical housing body, the main housing 10 is made such that the rear spacer 30 can freely rotate therein. The guide shaft 22 is mounted on the support 21 of the bottom cover 20, and is inserted into a hole, which is reserved from the lower portion of the main housing 10 and is engaged with the bottom cover 20, in alignment with the receiving groove 34 and the sleeve 33 of the partition plate 30, and thereby adjusts the partition plate 30 to a set position, such as the illustrated vertical position. The partition 30 in the vertical position minimizes the bad lighting effect caused by the bottom cover 20. The bottom cover 20 is then adhesively fixed to the main housing 10 to form a closed spherical housing, as shown in fig. 3.

The bulb lamp structure shown in fig. 4 is similar to that of fig. 2, in which the support member 21 provided on the bottom cover 20 is replaced with a motor housing 23, and the lower portion of the partition 30 is provided with a mounting interface 35 matching the outer profile of the motor housing 23. The orientation shaft 22 protrudes upward from the motor housing 23, and is disposed coaxially with the motor rotation shaft 24 protruding downward. In this configuration, the lighting effect of lunar phase change can be achieved by placing the motor rotation shaft 24 on a support surface (not shown), such that the motor rotation shaft 24 is stationary relative to the support surface and the motor housing 23 rotates due to gravity when the motor is in operation, thereby rotating the partition 30.

Fig. 5 is a schematic diagram of 3D printing and manufacturing of the globe lamp shown in fig. 4, wherein the main housing 10 is first printed and manufactured by the 3D printing head 50 on the printing table 51. When horizontal stack printing is performed to slightly over half of main housing 10, as shown in fig. 5, spacer 30 with the light source and battery and the like thereon is inserted therein, and then printing is continued until main housing 10 is completed. The substantially closed spherical light housing is then formed by aligning the spacer 30 in place by the orientation shaft 22 and completing the bonding of the bottom cover 20 to the main housing 10 as previously described with respect to fig. 2 and 3.

Fig. 6 shows the spherical lampshade body formed by the main lampshade body 10 and the bottom cover 20 according to the above-described structure of the present invention placed on the support 40. A power or charging device such as a wireless power transmitting coil (not shown) may also be provided on the support 40 to provide power to the globe lamp. Although bottom cover 20 is oriented downwardly, it may be oriented in any manner to provide corresponding moonphase illumination. Of course, such optional stand 40 may be omitted and the spherical housing may be placed on any suitable support surface, as previously described.

Fig. 7 shows another variant of the globe lamp according to the present invention, which is substantially similar to the structure shown in fig. 1-6, except that a cylindrical or ring magnet 26 is further provided at the bottom cover 20, and a corresponding larger ring magnet 42 is provided in the corresponding base 40. The positioning shaft 25 downwardly protruded from the lower cap 20 is protruded into the positioning groove 41 provided on the upper surface of the base 40 when the magnet 26 is coaxially arranged with the magnet 42 and the magnetic poles facing each other are opposite. Due to the interaction of the spherical lamp and the base, the spherical lamp can be accurately suspended at a preset height above the base 40, and then the accurate suspension lamp can be realized through the auxiliary positioning function of the positioning shaft 25, namely the waterproof flat offset function. The working principle of such a magnetic field structure can also be found in the applicant's prior patents CN100544183C and CN105790641B, which are incorporated herein by reference in their entirety.

In the configuration shown in fig. 7, the positioning shaft 25 may be omitted, and the globe lamp may be used as a floating body to be engaged with a floating base (a floater) to achieve a complete floating effect. The structure and operation of such suspensions and suspension bases are well known to those skilled in the art, as also disclosed in the applicant's above-mentioned patent. When in suspension, the spherical lamp as the suspension body has horizontal rotation freedom, so the baffle plate can realize the moon phase illumination effect which is changed continuously.

In addition, the spacer 30 in the above embodiment may be replaced with a flexible spacer such as a flexible light-shielding sheet, so that the assembly can be more easily and conveniently achieved and the device cost can be further reduced, as described in the following embodiment.

The bulb lamp configuration shown in fig. 8-11 is a variation of the embodiment shown in fig. 4. As shown in fig. 8-11, a motor, a flexible diaphragm 30 ', a light source (not specifically shown) and a battery (also not shown) on either or both sides of the flexible diaphragm 30', etc. are fixedly disposed on the bottom cover 20 to form a bottom cover assembly. In addition, a charging port 200 is disposed on the bottom cover 20 for charging the battery, and the battery can supply power to electric devices such as a motor and a light source. The motor has a portion or housing 23 to be rotated and a portion or terminal output shaft 24 to be stationary that extends slightly beyond the bottom cover 20, wherein the motor housing 23 is secured to the bottom cover 20. The output shaft 24 is oriented along the diameter of the globe lamp or the globe main housing 10 by means of the gear reduction system 234 of the motor. This embodiment differs from the embodiment shown in fig. 4 mainly in that a flexible baffle 30' is used instead of the baffle 30. The flexible baffle 30' may be made, for example, from an opaque plastic disc. The assembly process of the globe lamp of this embodiment is briefly described below with reference to fig. 8-11.

The bottom cap assembly shown in fig. 8 is first assembled with the flexible baffles 30' in a fully extended state. Next, the bottom cover assembly shown in fig. 8 is assembled into a spherical main cover body 10 formed by 3D printing in advance, wherein a circular mounting opening 11 is left at the bottom of the main cover body 10. As shown in fig. 9, the flexible baffle 30' on the bottom cap assembly is folded into a cylindrical shape; and then inserted into the main housing 10 through the mounting port 11 as shown in fig. 10. After the flexible partition 30' is completely inserted into the main housing 10, it is completely unfolded again by elasticity, as shown in fig. 11, thereby dividing the interior of the main housing 10 into two independent spaces. Finally, the bottom cover 20 is bonded and fixed at the mounting opening of the main housing 10 to form a complete globe lamp structure. In this configuration, the lighting effect of the lunar phase change can also be achieved by placing the motor output shaft 24 on a suitable support surface (not shown) such that the motor output shaft 24 is stationary relative to the support surface and the motor housing 23 rotates due to gravity when the motor is operating, thereby causing the baffle 30' to rotate.

In the embodiment of fig. 8-11, the charging port 200 of the bottom cover 20 may be omitted and a wireless power receiving coil may be provided in the globe lamp, such as on the bottom cover 20 or the main housing 10, to cooperate with a wireless power transmitting coil provided on an additional holder, for example, to power the electrical devices therein, as previously described with respect to the embodiment of fig. 6. In this case, the overall appearance of the globe lamp is more perfect.

Those skilled in the art will understand that: the lamp of the utility model is not limited to spherical shape, and can also be provided with a closed lampshade with any suitable shape; the spacer positioning adjustment means formed by the orientation shaft and the shaft receiving mechanism is not limited to the illustrated embodiment, and any suitable means for enabling adjustment of the position of the spacer within the main housing is possible. In addition, as an alternative, the partition board is not limited to a flat circular plate structure, and other hemispherical structures or other suitable special-shaped structures for limiting the light emitting range can be adopted. Furthermore, as an alternative, it is even possible to omit the inner partition and to use a material with poor light transmission, such as a light-impermeable material, to form a part, such as a half, of the spherical lamp housing, or to add a light-impermeable hemispherical cover outside the spherical lamp housing. These alternatives can each achieve a corresponding moon phase varying lighting effect of the globe lamp.
