Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flash housings lack the ability to easily and accurately adjust the beam angle of flash light for high-quality photography, as the short duration of flash light makes fine-tuning the illuminated area challenging.
Innovation Solution
A flash housing with a simulation light generator element, comprising multiple LED elements and a zoom element, allows for the simulation of the flash light beam lobe with a controllable beam angle, enabling manual adjustment of the flash light setting by simulating the flash light beam for a longer period, thereby aiding photographers in fine-tuning the beam angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flash light is used for photography, then the illuminated area can be controlled, but the short duration of flash light makes fine-tuning the beam angle difficult
Solution Approach 1:
The patent applies preliminary action by introducing a simulation light generator that activates before the actual flash to allow photographers to preview and adjust the beam angle coverage. The simulation light projects a visible beam lobe that mimics the flash light's angular distribution, enabling fine-tuning of the zoom element position before the brief flash discharge occurs.
Solution Approach 2:
The simulation light generator serves as an intermediary between the photographer and the flash light system. It translates the invisible angular parameters of the flash beam into a visible, adjustable simulation that photographers can observe and manipulate, bridging the gap between the long-duration adjustment needs and the short-duration flash discharge.
2Measurement precision
If multiple LED elements with different beam angles are used for simulation, then accurate flash light simulation is achieved, but device complexity increases
Solution Approach 1:
The simulation light generator is segmented into multiple LED elements, each with different beam angles, that can be independently controlled. This segmentation allows the system to simulate various flash light beam lobes by activating appropriate combinations of LEDs, providing accurate representation of different flash configurations without requiring a single complex adjustable LED.
Solution Approach 2:
The system employs dynamic control of multiple LED elements through a control unit that adjusts which LEDs are activated based on the desired simulation parameters. This dynamic switching between different LED combinations allows accurate simulation of various beam angles while keeping the physical structure relatively simple.
