Single-base multi-column light lamp improved structure

The improved structure of the single-column multi-column light lamp in the present case, especially when the believer wants to know the position of the light of a certain light lamp main body arranged by the temple in a single-base multi-column light, The convenient effect of positioning the position to a certain position.

According to the setting, the bright lights in the large and small temples in China are mainly used to provide believers with the purpose of praying for the purpose of praying for the purpose of praying, and then they can get rid of the evil spirits and get a heart and faith.

In the case of the current bright light, many of the main bodies of the light lamp are fixed and placed in the temple, and the main system of the light lamp is stacked in a layer by a plurality of layers of the lamp holder body, and each lamp holder body is The horizontal ring is provided with a plurality of frame seats, and the same number of bright lamp holders with bright lights can be embedded in the frame, and the light lamps in each of the bright lamp holders represent the blessing lamp positions provided by the believers.

However, the main body of the above-mentioned light lamp is fixedly installed in the temple for the believer to achieve the purpose of praying by lighting the ceremony, and it is cylindrical. Therefore, if the believer applies for lighting to the temple, he is arranged to light. The position is hidden behind the main body of the cylindrical light, it will not be easy to find, it will take time to find one by one, not only takes time, but also not humanized, and needs to be improved.

Furthermore, there is a manufacturer of bright lamps in the market. For the aforementioned lack, a rotating light main body is used, and the main body of the light lamp is placed on a turntable, and the center of the light main body is provided with a rotating shaft, and a motor is used. The belt rotates the rotating shaft to relatively rotate the main body of the light lamp to overcome the problem of the fixed light lamp.

The above-mentioned rotating type bright lamp can rotate the rotating shaft by the main body of the light lamp, and the main body of the light lamp is connected with the light to achieve the purpose of rotating the light. Because of the believers who have a bright light, will there be a request to see the temple to help them light up? Where is the bright light of the lighting? Is the light of the spot bright? And so on, so at this time, if the main system of the entire light is rotating, the temple personnel must turn off the control power to stop the whole light main body, to provide the believers to watch and confirm, causing inconvenience and troubles; When the main body of the light lamp is turned off when the control power is turned off, the main body of the light lamp that is rotated by the motor to drive the rotating shaft by the motor is not determined at the position where the control power is turned off, so it is still necessary to manually Rotating the main body of the light lamp; in particular, as a rotating shaft of the main body of the light lamp, it is first connected to the belt and then connected to the motor, and the entire weight of the entire body of the light lamp is used, so that even the main body of the light lamp is manually rotated. It still takes a lot of effort to rotate the position of the light of the believer's lighting to the believer to provide viewing confirmation. Therefore, the overall operation is still quite troublesome and needs to be improved.

Further, in order to improve the above-mentioned deficiencies, the applicant has filed a new patent for the "Bright Light Improvement Structure" No. M392613, which was submitted to the Bureau of the People's Republic of China and approved on November 21, 1999. It includes: a base, a rotating device, a motor, a rotating shaft, a placing seat, an inductive device, a light main body, and a pressing turntable; wherein the rotating device and the motor are disposed inside the base, and the rotating device cooperates with the motor to rotate; the rotating shaft bottom portion and the rotating device The connecting seat is connected to the rotating device and arranged above the base; the main system of the bright lamp is composed of a plurality of bright lamp holders with a light lamp inside, and the main body of the light lamp is placed on the rotating shaft and placed on the placing seat; The turntable is arranged on the top surface of the main body of the light lamp, and the main body of the light lamp is press-bonded between the placing seat and the pressing turntable by the joint member; the sensing device is electrically connected with the motor, and the rotating positioning control is performed on the main body of the light lamp; When the believer wants to know the position of the lighting, it can control the rotation of the main body of the light, and the convenience of rotating the position of the believer to a certain position.

The above-mentioned patent structure is used for "single-column light", that is, the main body of each of the light lamps of the column, which must be rotated by a rotating device, and must be coupled with a sensing device and the motor. By making electrical connections, when the believer wants to know the position of the lighting, by controlling the rotation of the main body of the light, it provides a convenient effect of rotating the position of the believer to a certain position; however, because each temple provides believers The number of lights that light up, often depending on the size of the temple space With the addition of settings, the number of bright lights that provide light to believers in each temple is often not the number of bright lights on the main body of a light lamp with one of several light lamps. Instead, it uses a single-base multi-column. The arrangement of the main body of the light lamp greatly increases the number of bright lights that provide lighting. Therefore, if the applicant is to create the structure of the case, a rotating device, a motor and a motor must be provided for each column of the light. The inductive device, which invisibly increases the complexity and cost of fabrication and assembly, does not provide the traditional single-base multi-column lamp, and there is still room for improvement.

In view of the lack of the above-mentioned conventional structure, the creator has exhausted his mind and research and design, and persists in the creative spirit of perseverance. After painstaking research and repeated tests and experiments, it is fully improved and conceived and improved. To complete this creation.

This creation is to improve the aforementioned structural defects and unsatisfactory. Therefore, the main purpose of the present invention is to provide a single-base multi-column light-light improved structure comprising: a base, a base, a revolution, a rotation, a column of light, a pressing disk The revolution part comprises: a revolution turntable having a main rotating shaft, a support seat respectively disposed on the main rotating shaft, and a pulley, and the pulley is coupled with the elliptical wheel on the motor rotating shaft of the one revolution part by the belt; the rotating part The utility model comprises: a plurality of shaft rods, wherein the upper part of each shaft rod passes through the revolution rotary table of the revolution part, and the bottom end of each shaft rod is fixed on the support seat of the main rotation shaft, and each pulley shaft is provided with a pulley and a rotation a turntable, each of which is disposed on the pulleys of the plurality of shafts and coupled to an elliptical wheel on a rotating shaft of the rotating shaft of the motor by a belt; the main system of the plurality of column lights is respectively set on the rotating turntable of each shaft In particular, a revolving portion sensing device is disposed between the pulley and the base of the revolving portion, and the revolving portion sensing device is electrically connected to the revolving portion motor, and the rotation portion is sensed between each of the rotation rotating table and the revolution rotating table of the rotation portion. Device The rotation portion sensing device is electrically connected to the rotation portion motor; accordingly, when the believer wants to know that the temple is arranged in the lighting position of a certain light main body of the multi-column light, Rotating positioning of the revolution part and the rotation part to facilitate the rotation position of the lighting position to a certain position.
