Solution Overview
Problem
Portable lights lack versatility and efficiency in light direction adjustment and heat dissipation, with existing designs often limiting the user's ability to change light orientation and managing heat effectively.
Innovation Solution
A portable light with a pivotable light head featuring a heat sink made of metallic material, integrated lens sections for light diffusion, and a control panel for switching between spot and flood modes, allowing the light head to pivot up to 110 degrees and efficiently dissipate heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light head is made fixed in conventional portable lights, then the structure is simple and easy to manufacture, but the user cannot adjust the light direction which reduces versatility
Solution Approach 1:
The light head is made pivotable rather than fixed, allowing dynamic adjustment of light direction. The pivotable coupling mechanism enables the light head to rotate and change orientation while maintaining electrical and mechanical connections, resolving the contradiction between versatility and complexity.
2Temperature
If conventional portable lights use basic heat management, then the device structure remains simple, but heat dissipation efficiency is insufficient leading to reduced performance
Solution Approach 1:
The heat sink is designed with an extended surface area structure that increases the surface area available for heat dissipation. This thermal management structure efficiently conducts and radiates heat away from the LED light sources, maintaining optimal operating temperatures without excessive complexity.
3Productivity
If portable lights use a single light source, then the device complexity is low, but the light output versatility and lumen efficiency are limited
Solution Approach 1:
Multiple LED light sources are integrated into a single light head assembly, combining their light output to achieve higher overall lumens efficiency. The heat sink structure consolidates the thermal management for all light sources, and the pivotable mechanism统一管理 the entire multi-source configuration, resolving the contradiction between productivity and complexity.

AI summary
A portable light includes a body having a first end and a second end. The body defines a longitudinal axis extending through the first end and the second end, and is configured to receive a battery. The portable light also includes a light head pivotably coupled to the first end of the body, a first light source supported by the light head, and a second light source supported by the light head. The first light source includes a spot light emitting diode configured to emit light in a direction substantially parallel to the longitudinal axis, and the second light source includes a flood light emitting diode configured to emit light in the direction substantially parallel to the longitudinal axis. The portable light further includes an actuator supported by the body and operable to selectively turn on the first light source and the second light source.
