Detachable External Flash Lamp for Front Fill Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The light-emitting surface of the lamp head of the camera-mounted flash facing upward blocks light below it, resulting in low brightness in front of the flash and affecting photography imaging effects.
Innovation Solution
An external flash lamp detachably mounted on the camera-mounted flash, with a light-transmitting window for emitting light towards the front side, electrically connected to the camera-mounted flash, either wired or wirelessly, to supplement the lighting range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light-emitting surface of the lamp head faces upward to achieve reflected lighting effect, then the lighting direction can be adjusted, but the light below the light-emitting surface is blocked by the lamp head, resulting in low brightness in front of the flash
Solution Approach 1:
The invention divides the lighting system into two independent parts: the original camera-mounted flash (providing upward reflected lighting) and the external flash lamp (providing forward direct lighting). This segmentation allows each component to perform its specific lighting function without interfering with the other, solving the blocking problem while maintaining lighting direction flexibility
Solution Approach 2:
The invention adds a new spatial dimension to the lighting system by mounting the external flash lamp on the front side of the camera body (different from the upward-facing lamp head). This dimensional addition provides light from a previously unused direction, eliminating the shadow area in front of the flash while preserving the original reflected lighting capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances lighting effect by supplementing the lighting range of the camera-mounted flash, improving user experience by ensuring brighter illumination in previously dark areas.
Implementation Method 1
light emitted by a light source in the external flash lamp is emitted toward the front side of the external flash lamp through the light-transmitting window
Implementation Method 2
the external flash lamp further includes a Fresnel lens provided at the light-transmitting window

AI summary
An external flash lamp (10) and a flash lamp system (100). The flash lamp system (100) comprises an external flash lamp (10) and a set-top flash lamp (20). After the external flash lamp (10) is detachably fixed to the set-top flash lamp (20), the external flash lamp (10) can be electrically connected to the set-top flash lamp (20), so as to transmit a control signal and an operating current. The illumination range of the external flash lamp (10) can supplement the illumination range of the set-top flash lamp (20), thereby solving the problem of low brightness of some areas.
