Combined Torch and Nightlight Device with Segmented Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for torch and nightlight functions are typically separate, leading to clutter and inefficiency when both functions are needed in the same area, and existing combined solutions suffer from complex components and light leakage issues.
Innovation Solution
A combined lighting device with multiple light sources, where one source emits light forward for torch use and another source emits a glow internally for nightlight use, with electrical connection required to activate the nightlight mode, ensuring efficient operation and minimizing light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single light source is used for both torch and nightlight functions, then the device can be compact, but light leakage occurs and light intensity is reduced
Solution Approach 1:
The patent divides the lighting system into separate light sources: a first light source for torch function and a second light source for nightlight function. This segmentation allows each light source to be optimized for its specific function without interfering with the other, eliminating light leakage issues while maintaining compact device size.
2Ease of operation
If masking is used to control light direction, then light can be directed properly, but device complexity increases
Solution Approach 1:
Instead of using complex masking mechanisms to control a single light source, the patent segments the lighting system into multiple light sources with fixed orientations. The first light source is positioned to emit light forward for torch use, while the second light source emits light internally for nightlight effect, eliminating the need for masking components.
3Illumination intensity
If two separate devices are used for torch and nightlight functions, then each function can be optimized, but space clutter increases
Solution Approach 1:
The patent merges two separate lighting devices (torch and nightlight) into a single integrated device. By combining a first light source for torch function and a second light source for nightlight function within one housing, the device provides both lighting functions in a single unit, reducing space clutter while maintaining optimized performance for each function.
Solution Approach 2:
The lighting device is designed with multi-functionality, serving both as a torch and a nightlight. The housing contains multiple light sources that can be selectively activated based on the desired function, making the device universal and eliminating the need for separate torch and nightlight devices.
4Adaptability or versatility
If multiple light sources are used for different functions, then light intensity and function are improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by creating distinct lighting zones with separate light sources: a first light source positioned for forward emission (torch) and a second light source positioned for internal emission (nightlight). This segmented approach provides functional versatility while keeping the overall device structure simple and manageable.
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 device efficiently operates as both a torch and nightlight without clutter, ensuring proper light intensity and functionality by using separate light sources that are only activated in their respective modes, reducing the need for complex masking and minimizing light leakage.
Implementation Method 1
a first light source mounted so as to emit light, when illuminated, in a direction substantially towards a first face of the housing
Implementation Method 2
at least a further light source mounted such that when illuminated, light is emitted in a direction other than towards said first face to the interior of the housing and passes through at least part of the wall of the housing

AI summary
The invention to which the application relates is a lighting means which is provided in a form to allow at least two lighting functions to be created. A first lighting function is in the form of a torch and the second function is as a nightlight with a glow lighting effect. In one arrangement the lighting means include a housing which can be gripped to allow the housing to be held as a torch and in the second function the illumination of a light source causes a glow effect through the wall of the housing to create a nightlight effect.
