Photoflash

The photoflash circuit is depicted above. The Seagulls SD-150 type studio flash integrates a formative light source and an intense photography light source, accompanied by an advanced synchronous remote control device for internal light modulation. This configuration allows multiple electronic umbrella lamps to flash simultaneously, achieving a substantial lighting effect during shooting. K1 serves as the power switch, K2 is the weak light switch for the model lamp, K3 is the strong light switch for the model lamp, S1 functions as the flash trigger button, S2 is the optical synchronous flash interface, and S3 is the camera synchronous flash interface.

The Seagulls SD-150 studio flash circuit is designed to provide versatile lighting solutions for photography. The circuit's primary components include a power supply, control switches, and synchronization interfaces, all of which contribute to its functionality.

The power switch (K1) is crucial for controlling the overall operation of the flash unit. When activated, it powers the entire circuit, allowing for the operation of the light sources. The weak light switch (K2) and strong light switch (K3) enable the user to select the desired intensity of the model lamp, providing flexibility for different shooting conditions. This feature is particularly useful in studio settings where lighting requirements can vary significantly.

The flash trigger button (S1) initiates the flash discharge, allowing the photographer to capture images at the precise moment of illumination. This button can be activated manually or through a remote trigger, depending on the setup. The optical synchronous flash interface (S2) allows for synchronization with other flash units that operate on optical sensors, enabling multiple flashes to work in harmony. The camera synchronous flash interface (S3) connects directly to the camera, ensuring that the flash fires in sync with the camera shutter, which is essential for capturing well-exposed images.

Overall, the Seagulls SD-150 photoflash circuit exemplifies a well-engineered solution for achieving high-quality lighting in photography, combining advanced control features with reliable performance.The photoflash circuit is showed as above. The seagulls SD - 150 type studio flash combines formative light and photography intense light source also accompanied by advanced synchronous remote control device of inside light modulation, which makes many electronic umbrella lamp also flash to achieve much light shooting effect. K1 is power switch, K2 i s weak light switch of model lamp, K3 isstrong light switch of model lamp, S1 is flash trigger button, S2 is optical synchronous flash interface, S3 is camera synchronous flash interface. 🔗 External reference
