LED Bulb Orientation for Operatory Light Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional operatory light bulbs emit light in all directions, including directly through the lens, which can lead to inefficiencies and potential glare issues, whereas existing LED bulbs do not effectively utilize the lens for light emission.
Innovation Solution
An LED bulb is designed such that it emits light only towards the reflector within the operatory light, with the LED positioned to direct light towards the socket, ensuring that only reflected light passes through the lens, utilizing a heat sink, control circuitry, and a specific orientation to manage heat and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional bulbs emit light in all directions, then light coverage is comprehensive, but light utilization efficiency deteriorates and glare issues occur
Solution Approach 1:
The LED bulb emits light in a specific direction (toward the reflector) rather than uniformly in all directions. This localized light emission direction optimizes the use of light through the lens while preventing direct glare, resolving the contradiction between light utilization efficiency and glare reduction.
2Productivity
If LED bulbs are positioned to emit light toward the lens, then light emission efficiency is improved, but direct light causes glare and existing LED bulbs do not effectively utilize the lens
Solution Approach 1:
The reflector acts as an intermediary between the LED light source and the lens. Light from the LED is directed toward the reflector, which then redirects it through the lens, allowing effective lens utilization while preventing direct light from causing glare.
3Object-generated harmful factors
If LED is positioned to direct light toward the socket, then only reflected light passes through the lens, but light utilization efficiency may deteriorate
Solution Approach 1:
The design converts what might be considered wasted light (light directed toward the socket and reflector rather than directly through the lens) into beneficial reflected light that passes through the lens. The reflector captures light that would otherwise be lost and redirects it usefully through the lens, improving overall light utilization while maintaining glare reduction.
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
This configuration enhances light utilization and reduces glare by ensuring all light emitted by the LED is reflected through the lens, improving the operational efficiency and user experience of the operatory light.
Implementation Method 1
a bulb that includes a light emitting diode (LED) positioned such that when the bulb is installed into a socket of the operatory light and powered, none of the light emitted from the LED is emitted directly through a lens of the operatory light; only reflected light passes through the lens of the operatory light
Implementation Method 2
The LED may be oriented to direct light toward a base of the replacement bulb and the base of the replacement bulb may be configured to couple with a socket of an operatory light
Data Source
AI summary
An operatory light may comprise a bulb that includes a light emitting diode (LED) module positioned such that when the bulb is installed into a socket of the operatory light and powered, none of the light emitted from the LED is directed directly toward a lens of the operatory light, and only reflected light passes through the lens of the operatory light.
