Description

Luminous rotating object and its motor

This application is a divisional application of an invention patent application with the application number "201110071050.5", the application date being March 24, 2011, and the invention name being "rotating lamp head".

technical field

The present invention generally relates to rotating light emitting objects. More specifically, it relates to motors used to rotate light-emitting objects.

Background technique

Existing rotating luminaires usually include a rotatable lampshade so that the luminaire has better visual and display effects and widens its application range. However, the structure of the existing rotating lamps is complicated. In order to rotate the lampshade, the entire lamp including the lampshade needs to be designed as an integral closed type. This kind of complex-structured one-piece closed rotating lamp not only has high cost, but also is not conducive to the replacement of light sources such as light bulbs and lamp tubes, and often requires professional maintenance personnel to complete the replacement of light sources. In addition, when designing the transmission mechanism, the existing rotating luminaires integrate the transmission mechanism and the specific structure of the specific luminaire. For example, one luminaire can only be adapted to one lampshade, resulting in the adaptability and versatility of the luminaire. very bad.

In addition, in the existing rotating device, not only a separate motor is required, but also the output shaft of the motor and the rotation axis of the rotating body need to be staggered from each other. This results in a complex structure and an excessively large volume of the entire rotating device.

Detailed ways

Exemplary embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to FIG. 1 , a rotating lamp head (or may simply be referred to as a “motor”) according to a first embodiment of the present invention includes a substantially cylindrical or cylindrical housing 1 . The housing 1 has a first longitudinal end and an opposite second longitudinal end. The first longitudinal end of the housing 1 is closed by a cover plate 11 . Both the first and second longitudinal ends are provided with a central opening to allow the substantially cylindrical lead post 2 to pass longitudinally therethrough.

The motor stator 3 is disposed around the inner peripheral surface of the housing 1 . The (hollow) shaft 5 is rotatably mounted around the lead post 2 via a bearing 7 . The motor rotor 4 is fixed on the rotating shaft 5 and arranged coaxially with the motor stator 3 . The lead post 2 passes through the longitudinal cavity of the rotating shaft 5 and passes out of the casing 1 through the above opening. The lead post 2 is also provided with a radial through hole 6 so that the lead cavity defined by the lead post 2 communicates with the interior of the housing 1 .

The lampshade bracket 12 is rotatably mounted around the lead post 2 and protrudes from the first longitudinal end of the housing.

The output gear 8 is fixed on the rotating shaft 5 . The driven gear 13 is fixed on the lampshade bracket 12 . The at least two-stage intermediate reduction transmission gear train 10 is mounted on the fixed gear train shaft 9 and meshes with the output gear 8 and the driven gear 13 respectively. In this way, the high-speed rotating shaft 5 can drive the lampshade support 12 to rotate slowly (for example, several revolutions per minute) through the above-mentioned reduction gear transmission system.

Fig. 2 shows a rotating lamp head according to a second embodiment of the invention. The rotating lamp head shown in Fig. 2 is similar to the rotating lamp head shown in Fig. 1, the difference lies in its reduction gear transmission system. Referring to FIG. 2 , the output gear 8 is fixed on the rotating shaft 5 . The planet gear carrier 18 is fixed on the lampshade bracket 12 . The inner gear 16 of the planetary gear train is fixed on the inner peripheral wall of the housing 1 . The planetary gear 17 is installed on the planetary gear carrier 18 and meshes with the output gear 8 and the internal gear 16 of the planetary gear train respectively. In this way, the planetary gear 17 revolves around the inner gear 16 of the planetary gear train while being driven by the output gear 8 , thereby driving the planetary gear carrier 18 and thus the lampshade support 12 to rotate slowly.

Fig. 3 and Fig. 4 respectively show the rotating lamp head installed with the light source receiving seat 14 according to the first embodiment of the present invention. In FIG. 3 , the light source receiving base 14 is fixed or detachably mounted on the first end of the lead post 2 (the first longitudinal end of the housing). In FIG. 4 , the light source receiving base 14 is fixed or detachably mounted on the second end of the lead post 2 .

FIG. 5 shows a rotating pendant light according to an embodiment of the present invention, including the rotating lamp head shown in FIG. 3 , a lampshade 20 and a light source (illustrated as a bulb) 19 . The lampshade 20 can be detachably mounted on the lampshade bracket 12 by any suitable fastening means such as compression nuts 15 . The light source 19 is received in the light source receiving seat 14 . The power line 23 is connected to the light source receiving base 14 or the light source 19 through the lead post 2 of the housing 1 through the connector 22 from the ceiling, and is also connected to the motor stator 3 through the through hole 6 .

FIG. 6 shows a rotating pendant light according to a preferred embodiment of the present invention, including the rotating lamp head shown in FIG. 4 , lampshade 20 and light source 19 . With the chandelier of this structure, the entire rotating lamp head can be completely enclosed in the lampshade 20, so that the whole chandelier appears more tidy and compact, and has a more beautiful appearance.

FIG. 7 shows a rotary desk lamp according to an embodiment of the present invention, including the rotary lamp head shown in FIG. 3 , a lampshade 20 , a light source 19 and a desk lamp base 21 for supporting the housing 1 .

FIG. 8 shows a rotary desk lamp according to a preferred embodiment of the present invention, including the rotary lamp head shown in FIG. 4 , a lampshade 20 , a light source 19 and a desk lamp base 21 for supporting the housing 1 . The rotating table lamp with this structure also has a neat and compact overall appearance.

FIG. 9 shows a luminous rotating globe according to an embodiment of the present invention, including the rotating lamp head shown in FIG. 3 , a lampshade 20 in the form of a globe, a light source 19 and a desk lamp base 21 for obliquely supporting the housing 1 .

10 shows a luminous rotating globe according to a preferred embodiment of the present invention, including the rotating lamp head shown in FIG. The luminous rotating globe of this structure also has a neat and compact overall appearance.

Certainly, in the embodiment of FIG. 8 , the lampshade 20 can also be configured in the shape of a six-sided three-dimensional photo frame, so that the entire desk lamp can be changed into a six-sided three-dimensional photo frame that can rotate by itself. In addition, the lampshade 20 can also take the form of any advertising light box with a desired shape and/or pattern.

Since the rotating lamp head of the present invention is actually a slow motor, the modularized rotating lamp head has a smaller volume and a more compact structure. Obviously, the modular swivel lamp head of the present invention can be completely turned into a universal replacement for lamp mounts on ordinary (non-rotating) luminaires. By simply replacing the lamp holder installed on the ordinary lamp with the modularized rotating lamp holder of the present invention, the replacement of the existing ordinary lamp can be realized very conveniently.

Those skilled in the art should understand that the above embodiments are only used to explain and describe the present invention, and are not intended to limit it in any way. According to practical application (for example, in the case of a pendant lamp), the lead post 2 can be omitted, as long as the lampshade bracket 12 and the hollow rotating shaft 5 are arranged to be rotatable relative to the housing 1 . In addition, in the present invention, the reduction transmission system is not limited to the illustrated gear transmission system, but any suitable reduction transmission system such as a pulley transmission system commonly used in the field can be used.
