Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stage lights installed outdoors are vulnerable to damage from sunlight, which causes overheating and reduces their service life due to the lack of effective sunlight avoidance mechanisms in existing technologies.
Innovation Solution
A stage light with a light avoiding system that includes a gravity sensor and a control assembly to rotate the light head when the light is in a power-off state, positioning it to avoid sunlight, and a solar panel to generate electricity for the rotation mechanism, ensuring the light head is not exposed to direct sunlight, thereby preventing overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stage light is installed outdoors with fixed position, then it can provide stable lighting performance, but the light head will be exposed to sunlight causing overheating and damage to internal components
Solution Approach 1:
The patent applies the dynamics principle by enabling the light head to rotate automatically when in standby state. The rotation mechanism transforms the fixed position into a dynamic adjustment capability, allowing the light head to change its orientation and avoid direct sunlight exposure while maintaining stable installation. This resolves the contradiction by introducing motion capability without compromising the overall stability of the outdoor installation.
Solution Approach 2:
The patent implements preliminary action by detecting the standby state of the stage light in advance and automatically rotating the light head to an optimal position before sunlight exposure becomes problematic. The control system anticipates potential overheating issues and takes preventive action by adjusting the light head orientation, thereby avoiding damage before it occurs.
2Object-affected harmful factors
If the light head rotates to avoid sunlight, then sunlight damage is prevented, but additional control mechanisms and energy consumption are required
Solution Approach 1:
The patent applies the self-service principle by designing an automatic control system that detects the stage light's own standby state and autonomously rotates the light head without requiring external intervention. The system monitors its own operational status and takes self-initiated protective action, reducing the need for complex external control mechanisms and simplifying the overall system architecture.
Solution Approach 2:
The patent implements feedback by using the standby state detection signal as both an input condition and a control trigger. The control system receives feedback about the light's operational state and uses this information to automatically activate the rotation mechanism when needed, creating a closed-loop control system that responds to actual operating conditions rather than requiring complex pre-programming.
3Reliability
If the light head rotates to avoid sunlight, then internal components are protected, but energy is consumed for the rotation mechanism
Solution Approach 1:
The patent applies periodic action by limiting the rotation operation to specific periods - only when the stage light is in standby state. During operational periods, the light head remains fixed to avoid energy consumption. This periodic activation strategy ensures component protection is provided precisely when needed (during non-lighting periods when sunlight exposure is most problematic) while minimizing energy usage by avoiding unnecessary rotation during active lighting periods.

AI summary
A stage light free from damage of sunlight includes a light body and a control assembly, and a light avoiding system. When the light body is in a power-on state, the control assembly controls the light avoiding system not to work; and when the light body is in a power-off state, the control assembly controls the light avoiding system to implement a light avoiding action. According to the present invention, smart light avoiding according to a sunlight status can be achieved by means of a light avoiding system. The light avoiding system can be in multiple light avoiding manners that can be set separately or in a combination manner which is more targeted. A gravity sensor is used to detect an installation position of a stage light, and a main controller calculates included angles between the directions of a light head and a gravity direction and compares the angles until the smallest included angle is calculated. That is, the light head of the stage light is adjusted towards the gravity direction as close as possible to prevent the sunlight from irradiating the lens of the light head. The light avoiding system has advantages of a high automatic recognition level, a flexible access system, and being cost-effective and easy to implement.
