Intelligent electronic ballast for high-power film and television lamp and driving method thereof

Abstract

The invention discloses an intelligent electronic ballast for a high-power film and television lamp and a driving method thereof. The intelligent electronic ballast comprises a plurality of ballast modules, a first trigger and a controller, the input ends of the ballast modules are connected with an external alternating current, and the output ends of the ballast modules are connected with the first trigger; the output end of the first trigger is used for being electrically connected with an external film and television lamp, the trigger is respectively connected with the plurality of ballast modules through electric control devices, under the control of the controller, the electric control devices corresponding to the plurality of ballast modules have a synchronous on-state or off-state, and the controller is used for adjusting the output power of each ballast module. Therefore, the total output power of the plurality of ballast modules is matched with the external film and television lamp. According to the intelligent electronic ballast for the high-power film and television lamp and the driving method thereof, adaptation to the high-power film and television lamp is achieved, overstock of ballast equipment of an equipment leasing company is reduced, and the cost pressure is well relieved.

Description

technical field [0001] The invention relates to the technical field of electronic ballasts, in particular to an intelligent electronic ballast for high-power film and television lamps and a driving method thereof. Background technique [0002] With the continuous development of lighting technology, the lighting and cost requirements for film and television shooting are also constantly increasing, which will also become an inevitable trend in the development of the film and television lighting market. [0003] Today's market is dominated by traditional film and television lamps, and one ballast must match one lamp, which has caused a backlog of equipment and cost pressure for film and television lighting equipment rental companies to a great extent. Now with the development of the film and television lighting market, 1.8KW and 4KW have become the current mainstream shooting lighting, but shooting lighting in other power ranges (especially high power such as 6 / 9KW, 12 / 18KW, 24...

AI Technical Summary

Problems solved by technology

[0006] 2) In terms of the volume and weight of film and television lamps: the greater the power of traditional film and television lamps, its volume and weight are also huge and heavy, which is not conducive to handling and on-site operation

[0007] 3) In terms of control method: the control method is extremely simple, which can only meet the simple requirements of switch dimming, and the accuracy of dimming cannot be adjusted with high precision, let alone adapt to the control requirements of modern intelligent development
