Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection lamps suffer from poor projection brightness and unclear projected images due to inadequate light concentration and distribution.
Innovation Solution
A projection lamp with a replaceable corrugated sheet and multiple light sources, where the light sources are inclined and pass through a first and second corrugated sheet, enhancing light concentration and distribution, and a pattern-changing gear mechanism allows for dynamic projection effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source is used, then the device complexity is low, but the projection brightness is insufficient
Solution Approach 1:
The patent combines multiple light sources (at least two LED light sources) into a single projection lamp assembly, merging their light output to achieve sufficient projection brightness while maintaining a compact structure. The light sources are arranged to illuminate the corrugated sheet from different angles, creating a combined lighting effect that enhances projection quality.
2Manufacturing precision
If light sources are arranged perpendicular to the corrugated sheet, then the light distribution is simple, but the projection clarity is insufficient
Solution Approach 1:
The patent employs asymmetric arrangement of light sources relative to the corrugated sheet, where light sources are positioned at different angles and heights. This asymmetric configuration creates varied light paths that interact with the corrugated surface to enhance projection clarity and prevent uniform lighting patterns that would reduce visual interest and clarity.
3Adaptability or versatility
If a fixed corrugated sheet is used, then the device complexity is low, but the adaptability for different projection patterns is limited
Solution Approach 1:
The patent incorporates a rotatable corrugated sheet mechanism that can be dynamically adjusted to different angular positions. This dynamic element allows the same physical component to produce different projection patterns by changing the orientation of corrugations relative to the light sources, thereby enhancing adaptability without requiring multiple fixed corrugated sheets.
Solution Approach 2:
The corrugated sheet is designed as a separate, replaceable component that can be segmented or modified to create different projection patterns. The sheet can be removed and replaced with different corrugated patterns, allowing users to adapt the projection lamp for different applications without changing the entire device structure.
4Illumination intensity
If multiple light sources are added, then the projection brightness improves, but the heat generation increases
Solution Approach 1:
The patent introduces a heat dissipation structure as an intermediary component between the light sources and the surrounding environment. This intermediary system actively manages and dissipates heat generated by multiple light sources, preventing temperature buildup while allowing the light sources to operate at high intensity for bright projection.
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 solution significantly increases projection brightness and clarity, enabling a more effective and versatile display of projected images with adjustable patterns and dynamic effects.
Implementation Method 1
A projection lamp generally uses an LED light source to illuminate a projection sheet
Implementation Method 2
Light emitted by the LED light source is condensed through a specific lens to illuminate the projection sheet
Implementation Method 3
Light emitted by the LED light source is condensed through a specific lens to illuminate the projection sheet
Data Source
AI summary
A projection lamp and a lamp holder include a housing defining a projection port, a lampshade covered on the projection port of the housing, and a projection lamp assembly. Light is emitted from the projection port. The projection lamp assembly includes at least two light sources and a first corrugated sheet. Patterns are provided on the first corrugated sheet. The at least two light sources are configured to emit the light. The light passes through the first corrugated sheet and the lampshade to emit out. Projection brightness of the at least two light sources is great and the first corrugated sheet is replaceable. A projected image is replaced by replacing a pattern-changing gear in tan inserting groove. Light strips are arranged on an outer wall of the projection lamp to create a visual atmosphere effect.
