Sighting Light Source Structure for Clear Aiming Point Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source structures in sighting devices suffer from structural self-reflection, leading to ambiguous aiming point outlines due to stray light at the edge of the aiming point.
Innovation Solution
A light source structure comprising a substrate, light-emitting chip, bonding wire, light-absorbing glue, and optionally a transparent protective glue layer, dam, mounting seat, and glass cover plate, designed to prevent light reflection by omitting a light-transmitting protective layer, ensuring a clear aiming point edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light-transmitting protective layer is added to protect the light-emitting chip, then the protection and durability are improved, but light reflection occurs causing ambiguous aiming point outlines
Solution Approach 1:
The patent converts the harmful light reflection from the protective layer into a beneficial effect by applying a reflective layer on the outer surface of the protective layer. This reflective layer redirects the reflected light back toward the light-emitting chip, preventing stray light from reaching the aiming point and causing ambiguity. The harmful reflection is thus transformed into a mechanism that enhances aiming point clarity.
Solution Approach 2:
The patent applies a reflective layer in advance on the protective layer to prevent light reflection from causing harmful effects. By预先 (in advance) introducing this reflective layer, the system proactively counteracts the potential harmful reflection before it can degrade the aiming point outline, thereby maintaining clear edges and improving reliability.
2Object-generated harmful factors
If the light source structure is simplified by removing the protective layer, then light reflection is eliminated and aiming point clarity is improved, but the light-emitting chip becomes vulnerable
Solution Approach 1:
Instead of removing the protective layer, the patent retains it and adds a reflective layer to convert the harmful reflection into a beneficial effect. The reflective layer causes reflected light to return to the light-emitting chip rather than dispersing as stray light, thus maintaining both protection and eliminating harmful reflection effects.
Solution Approach 2:
The patent creates a composite structure by combining the protective layer with a reflective layer on its outer surface. This composite structure simultaneously provides mechanical protection through the protective layer and optical control through the reflective layer, resolving the contradiction between protection and light reflection.
3Object-generated harmful factors
If a reflective layer is added to the protective layer, then light reflection is controlled and aiming point outline clarity is improved, but the device complexity increases
Solution Approach 1:
The reflective layer serves multiple functions simultaneously: it controls light reflection to prevent stray light, maintains the protective function of the protective layer, and potentially enhances light extraction efficiency. This multi-functionality justifies the added complexity by delivering multiple benefits from a single component addition.
Solution Approach 2:
The reflective layer changes the optical properties of the protective layer surface by introducing reflectivity. This optical property change (from transparent to reflective) enables the system to control light behavior and eliminate stray light effects, improving aiming point outline clarity.

AI summary
The present disclosure relates to the illuminant structure technical field. Disclosed are a light source structure, a sighting device and a shooting device, wherein the sight light source structure is used for the sighting device. The light source structure includes a substrate, a light-emitting chip arranged on the substrate, a bonding wire configured for electrically connecting the substrate and the light-emitting chip, and light-absorbing glue coated on the bonding wire. By improving the structure of the light source structure, specifically, by not covering the light-transmitting protective layer on the light-emitting chip, the light-transmitting protective layer is effectively prevented from reflecting light, so that the aiming point formed by the light at the light-emitting place is gathered, and the edge of the aiming point has no stray reflected light so that the wheel library at the edge of the aiming point is clear.
