Lamp Protection Device for Stage Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stage lighting systems face a challenge in controlling the temperature of the lamp electrode when a light filter is used, as reflected light energy converges on the electrode, leading to excessive heat and reduced lamp life, while using a light filter with an included angle compromises the ideal optical effect.
Innovation Solution
A stage lighting source system with a lamp protection device comprising a non-transparent structure and mounting component, which absorbs and reflects light energy reflected from the filter, preventing excessive heat from reaching the electrode and allowing for a flat light filter without an included angle, ensuring uniform light color and extended lamp life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light filter is used perpendicular to the light axis to achieve ideal optical effect, then uniform light color is realized, but reflected light energy converges on the electrode causing excessive temperature and reduced lamp life
Solution Approach 1:
A lamp protection device is introduced as an intermediary component between the light filter and the lamp. This device includes a reflective surface that redirects reflected light energy away from the electrode, and a protective structure that shields the electrode from excessive heat, thereby enabling the use of perpendicular light filters without compromising lamp life
Solution Approach 2:
The lamp protection device converts the harmful reflected light energy into a beneficial direction by using a reflective surface to redirect it away from the electrode. The previously harmful reflected light is now redirected to a safe path, transforming the problem into a solution that maintains both optical quality and lamp durability
2Duration of action of stationary object
If a light filter with an included angle is used to control electrode temperature, then lamp life is extended, but uniform light color projection is compromised
Solution Approach 1:
The lamp protection device serves as a mediator that allows the light filter to maintain its ideal perpendicular orientation for uniform light color while the protective structure and reflective surface actively manage the reflected light energy to prevent electrode overheating, thus preserving lamp life
3Device complexity
If no lamp protection device is used to maintain simple structure, then device complexity is reduced, but electrode temperature control fails leading to accelerated lamp failure
Solution Approach 1:
The lamp protection device is segmented into distinct functional components: a reflective surface for redirecting light energy, a protective structure for shielding the electrode, and a mounting component for integration. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural simplicity and reliability
