Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting apparatuses with laser light sources do not effectively prevent unintentional exposure to laser light during light emitter replacement operations, posing a safety risk to users.
Innovation Solution
A lighting apparatus design that includes a light blocker mechanism, which engages with the light emitter to open and block the optical path of laser light during attachment and removal, ensuring the laser light does not leak outside during replacement operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the light emitter is made replaceable to enable maintenance and color changes, then the ease of operation is improved, but the risk of unintentional laser light exposure during replacement increases
Solution Approach 1:
The light blocker is pre-positioned in the optical path before the light emitter is removed. This preliminary action ensures that the optical path is blocked before any potential laser light leakage can occur during the replacement operation, thus preventing eye exposure while allowing easy replacement of the light emitter.
2Object-affected harmful factors
If a light-dispersing material is placed to reduce laser light coherence, then the safety from direct laser entry is improved, but the device complexity increases
Solution Approach 1:
Instead of adding complex light-dispersing materials to the optical path, the invention extracts and blocks the laser light path using a simple light blocker component. This approach eliminates the need for complex dispersing materials while effectively preventing laser light exposure during light emitter replacement.
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
The light blocker mechanism effectively prevents laser light from entering the eyes during light emitter replacement, ensuring user safety and allowing for safe and secure replacement of light emitters without exposing users to hazardous laser light.
Implementation Method 1
a light emitter which, when irradiated with laser light, radiates light by converting a wavelength of the laser light
Data Source
AI summary
A lighting apparatus including a base is provided. The base includes a through-hole. The through-hole is aligned with an optical path of laser light for receiving and transmitting the laser light. A light emitter which, when irradiated with the laser light transmitted through the through-hole, radiates light by converting a wavelength of the laser light. An attachment component is provided on the base for attachment of the light emitter to the base. The light emitter is removable from the base. A light blocker opens the optical path of the laser light by being contacted by the light emitter when the light emitter is attached to the base, and blocks the optical path of the laser light when the light emitter is removed from the base.
