Rotary advertisement lamp box

Abstract

The invention discloses a rotary advertisement lamp box, which comprises a rotary lamp holder and a lampshade in a advertisement lamp box form, wherein the rotary lamp holder comprises a shell, a motor stator, a rotating shaft, a motor rotor, a lampshade bracket and a deceleration transmission system, wherein the shell is provided with a first longitudinal end with an opening, and a second longitudinal end; the motor stator is arranged on the inner circumferential surface of the shell; the rotating shaft is positioned in the shell and is mounted by rotating relative to the shell and defines a cavity communicated with the opening at the first longitudinal end of the shell; the motor rotor is fixed on the rotating shaft and coaxial with the motor stator; the lampshade bracket is mounted by rotating relative to the shell and extends out of the first longitudinal end of the shell; and the deceleration transmission system is positioned in the shell and respectively connected with the rotating shaft and the lampshade bracket. According to the rotary advertisement lamp box, the modular rotary lamp holder is small in size and compact in structure; and the rotary advertisement lamp box can be completely matched with lamp holders and lampshades in any standard style.

Description

[0001] 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 [0002] The present invention generally relates to rotating light emitting objects. More specifically, it relates to rotating advertising light boxes. Background technique [0003] 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 profe...

Problems solved by technology

However, the structure of the existing rotating lamps is complex. In order to rotate the lampshade, the entire lamp including the lampshade needs to be designed as an integral closed

This kind of one-piece closed rotating lamp with complex structure is not only costly, but also 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 poor

[0004] 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
