Laser Apparatus Upward Terminal Units Compact Footprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semiconductor laser modules have a bar-like electrode that projects out of the package casing, leading to increased footprint and difficulty in space-saving when multiple modules are arranged, which is a challenge for applications requiring higher output power and compactness.
Innovation Solution
A laser apparatus with a semiconductor laser element mounted on a bottom plate and terminal units facing upward for external electrical connection, allowing for a compact design by eliminating the need for horizontal space allocation for terminal units, and a light source apparatus with multiple such laser apparatuses mounted on a base member to increase output power while reducing footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bar-like electrode projects out of the package casing, then external electrical connection is enabled, but the footprint increases and space-saving becomes difficult
Solution Approach 1:
The terminal unit is reoriented from a horizontal projection (bar-like electrode extending outward) to a vertical orientation (facing upward). This dimensional change allows electrical connection while eliminating lateral space occupation, directly resolving the footprint issue.
2Power
If multiple semiconductor laser modules are arranged to increase output power, then higher output power is achieved, but the footprint increases
Solution Approach 1:
By changing the terminal unit orientation to vertical, multiple modules can be arranged in a compact grid pattern without requiring additional lateral clearance for electrical connections, enabling higher output power with reduced footprint.
Solution Approach 2:
The terminal unit structure integrates the electrical connection function directly into the package casing topology, eliminating the need for separate external lead pins and reducing overall space requirements for multi-module arrangements.
3Ease of operation
If a bar-like electrode is used, then external electrical connection is achieved, but lead pins and soldering are required increasing complexity
Solution Approach 1:
The lead pins and soldering joints are extracted from the connection structure by replacing them with a terminal unit that provides direct electrical access through its upward-facing surface, simplifying the overall connection architecture.
Solution Approach 2:
The terminal unit serves multiple functions: it provides electrical connection, defines the package boundary, and enables simplified wiring. This multi-functionality reduces the need for separate components like lead pins and simplifies the connection process.
