LED Bracket Back Diffusion for Light Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamp beads have a limited light-emitting angle of 120° and exhibit weak light emission from the back surface, making the light output from the back surface significantly different from that of the front surface, even when using transparent brackets.
Innovation Solution
An LED bracket design featuring a front bracket with an LED lamp chip and a connected back bracket coated with a diffusion material, allowing light emitted from the lamp chip to be diffused and emitted from the back bracket, thereby matching the light effect from the front bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is emitted from the LED lamp chip towards the back bracket, then light can be transmitted through the bracket, but the light emitted from the back surface is very weak and quite different from that emitted from the front surface
Solution Approach 1:
The patent applies local quality by coating only the back bracket surface with diffusion material, creating different optical properties in different locations. The front bracket remains transparent for direct light transmission, while the back bracket has diffusion material applied to scatter and uniformly distribute the light that passes through it, thus improving light emission uniformity without compromising the overall illumination intensity
Solution Approach 2:
The diffusion material serves as an intermediary substance between the LED lamp chip and the external environment on the back surface. It mediates the light transmission process by scattering the light rays that pass through the bracket, converting the concentrated light into a more uniform distribution pattern, thereby improving the quality of light emission from the back surface
2Adaptability or versatility
If the bracket is made of transparent material to allow light transmission, then light can pass through to the back surface, but the transmitted light is still very weak
Solution Approach 1:
The patent applies color changes by using diffusion material with specific optical properties on the back bracket. This material alters the light characteristics by scattering and redistributing the transmitted light, effectively increasing the perceived light intensity and uniformity on the back surface while maintaining the transparent bracket structure for light transmission capability
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 diffusion material on the back bracket ensures that the light emitted from the back bracket is not substantially different from the front bracket, enhancing the overall light effect and uniformity of the LED lamp chip's output.
Implementation Method 1
a diffusion material is provided on a side of the back bracket away from the front bracket. light emitted in a direction close to the back bracket passes through the diffusion material and then emits from the back bracket
