[0024] Stage lighting is an important part of stage performances and is often used to create atmosphere on stage. Its colors are rich and colorful and ever-changing. At the same time, because of its real-time positioning, flexible steering, controllable color mixing and other characteristics, people use stage lights in evening parties, concerts, outdoor performances, urban lighting projects, entertainment venues, building decoration and other fields.

[0025] The power supply of a stage light is the core of the stage light and plays a vital role in the stage light. The power supply of the stage light is responsible for providing a stable power supply for various lighting equipment, so that the stage light can present various light and shadow effects as required. In an existing stage light, the driving device of the power supply is installed on the lamp body. This structural design will increase the weight of the lamp body and is not conducive to the heat dissipation of the driver. Therefore, the present application provides a power supply for a stage light with an LED driver.

[0027] Specifically, the mounting plate 2 of the present application can be fixed to the base 12 by bolts. In addition, in order to save the weight of the mounting plate 2, a plurality of hollow holes should be provided on the mounting plate 2 to save the material of the mounting plate 2 and reduce the weight.

[0028] In actual applications, the power supply body 5 supplies power to the lamp body 11, and the driving device 6 is arranged between the power supply body 5 and the load of the lamp body 11. More preferably, the heat dissipation fan 4 is arranged toward the driving device 6 and the power supply, and is used to dissipate heat from the driving device 6 and the power supply body 5. The driving device 6 of the present application uses the heat dissipation fan 4 of the power supply body 5 to dissipate heat synchronously, which can effectively reduce the temperature rise of the driving device 6 when in use, so that the driving device 6 can work stably.

[0029] The above-mentioned power supply for stage lights with LED drive, the stage lights include a lamp body 11 and a base 12, the power supply includes a mounting plate 2, a power supply body 5 and a driving device 6, the mounting plate 2 is fixed on the base 12, the power supply body 5 and the driving device 6 are both arranged on the mounting plate 2, the driving device 6 is arranged on one side of the power supply body 5, and the mounting plate 2 is also provided with a heat dissipation fan 4, and the heat dissipation fan 4 is arranged toward the driving device 6. The power supply is arranged on the stage light base 12 through the mounting plate 2, avoiding the need to set a receiving position for accommodating the driving device 6 on the lamp body 11 of the stage light, and removing the connecting line between the power supply and the driving device 6, reducing the interference to the driving, and increasing the reliability of the power supply driving. Moreover, a heat dissipation device can be arranged on the base 12 to dissipate heat with the power supply, which is beneficial to the temperature control of the heat dissipation of the driving.

For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
