Work Lamp Optical Layout for Even Illumination in a Compact Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lamp structures suffer from uneven brightness due to lamp beads being arranged opposite to the light outlet, leading to high brightness in certain directions and a large volume, resulting in a single irradiation direction and increased thickness.
Innovation Solution
A work lamp design featuring a first light-emitting assembly with a reflector to adjust light emission direction and a second light-emitting component with a light guide to provide even background light, along with a mounting boss for a compact and integrated layout, enhancing aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lamp beads are arranged opposite to the light outlet, then the brightness of the lamp beads is the highest, but the irradiation direction is single resulting in uneven brightness
Solution Approach 1:
The patent divides the light-emitting structure into multiple lamp boards (first light-emitting lamp board, second light-emitting lamp board, third light-emitting lamp board) arranged at different positions and orientations. Each lamp board emits light in a different direction, segmenting the single irradiation path into multiple paths that collectively provide uniform illumination across the working surface.
2Adaptability or versatility
If there are many stacked structures in the thickness direction of the whole lamp, then the lamp provides multiple light-emitting functions, but the lamp volume becomes large
Solution Approach 1:
The patent transitions from vertical stacking in the thickness direction to a planar arrangement where multiple lamp boards are distributed across the surface area. The lamp boards are arranged in a radial pattern around the light outlet, utilizing the two-dimensional surface space rather than consuming thickness, thereby maintaining multiple light-emitting functions while reducing overall lamp volume.
3Ease of operation
If the reflector is used to adjust light-emitting direction, then the light emission direction is controlled, but the structural complexity increases
Solution Approach 1:
The patent integrates the reflector function directly into the housing structure. The inner wall of the housing serves as the reflector surface, eliminating the need for a separate reflector component. This merging of the reflector function with the existing housing structure provides effective light direction control while avoiding additional structural complexity.
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 design achieves even brightness distribution with softer light emission and a more compact structure, improving the integrality and aesthetic appeal of the work lamp.
Implementation Method 1
the light emitted by the first light-emitting lamp board provided in the present application is reflected by the reflector for emission along the direction of the opening to form the main lighting
Implementation Method 2
the light guide is used for leading out the light emitted by the second light-emitting lamp board to provide even background light to obtain softer light
