Microscope Light Source Set for Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable minimized microscope devices often suffer from insufficient light due to the close proximity of the sample to the objective lens, resulting in a dark and unclear magnified image, which negatively impacts the observation experience.
Innovation Solution
A microscope device equipped with an additional light source set that includes a circuit substrate, battery, and light-emitting unit, where the light-emitting unit is positioned at the outer periphery of a cover body around the optical route, allowing the light beam to irradiate towards the center axis, providing additional illumination to the sample.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the microscope device is miniaturized to reduce overall volume, then the device size is reduced, but the distance between the sample and objective lens becomes very small causing insufficient light
Solution Approach 1:
The patent divides the lighting function into separate components by adding an additional light source set independent from the main microscope structure. This light source set includes a battery, circuit substrate, and light-emitting unit that can be attached separately to provide illumination without interfering with the miniaturized microscope body design.
Solution Approach 2:
The patent introduces a cover body as an intermediary component that houses the additional light source set. The cover body is annularly arranged around the optical route and positions the light-emitting unit at its outer periphery, allowing light to be directed toward the sample while maintaining the compact microscope structure.
2Illumination intensity
If the light source is positioned close to the objective lens to illuminate the sample, then illumination is sufficient, but the light source obstructs the optical route
Solution Approach 1:
The patent positions the light-emitting unit at the outer periphery of the cover body rather than on the optical axis. This radial positioning allows light to be directed toward the sample from the side, avoiding obstruction of the central optical route while still providing sufficient illumination intensity.
Solution Approach 2:
The patent directs light from the light-emitting unit specifically toward the sample area that needs illumination, rather than uniformly illuminating the entire optical path. The light is focused on the local region where the sample is positioned, ensuring adequate brightness without requiring a centrally positioned light source.
3Illumination intensity
If an additional light source set is added to provide illumination, then light intensity is sufficient, but the device complexity increases
Solution Approach 1:
The patent combines multiple functional components (battery, circuit substrate, and light-emitting unit) into a single integrated additional light source set that is housed within the cover body. This merging reduces the number of separate components and simplifies the overall device structure while still providing sufficient illumination.
Solution Approach 2:
The cover body serves multiple functions: it protects the microscope components, houses the additional light source set, and provides structural support for positioning the light-emitting unit. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
A microscope device for observing a sample. The microscope device and the sample are located on an optical route. The microscope device includes an objective lens unit and an additional light source set. The light source set includes a circuit substrate, a battery and a light-emitting unit. The circuit substrate has a power source portion and a light source portion electrically connected to the power source portion. A connecting member and the battery are arranged at opposite sides of the power source portion. The light-emitting unit is arranged on the light source portion, and the distance between the light-emitting unit and the center axis of the optical route is greater than the radius of the objective lens unit. The battery activates the light-emitting unit to generate a light beam, and the light beam irradiates toward the center axis of the optical route.
