Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LEDs emit light from a single side, limiting their light-emitting angle and application range, and increasing the number of LEDs to achieve double-sided emission increases cost and reduces service life due to heat dissipation issues.
Innovation Solution
An LED support with at least two light-exiting windows on its housing allows light from the LED chip to exit from both sides, enhancing the light-emitting angle and reducing light reflection and absorption, thereby improving light emission efficiency and application range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional LED emits light from a single side, then the structure is simple, but the light-emitting angle is limited and application range is restricted
Solution Approach 1:
The patent transitions from single-sided light emission to multi-sided light emission by adding light-exiting windows on multiple surfaces of the housing. This dimensional change in light emission direction enables the LED to be applied in scenarios requiring wider light distribution angles without fundamentally changing the LED chip itself, thus expanding application range while maintaining relatively simple structure.
Solution Approach 2:
The housing structure is designed to serve multiple functions: it provides mechanical protection for the LED chip, acts as a heat dissipation component, and functions as a light guide with multiple light-exiting windows. This multi-functionality allows a single component to achieve both structural support and enhanced light emission in multiple directions, expanding application versatility without proportionally increasing complexity.
2Adaptability or versatility
If multiple single-sided LEDs are used to achieve double-sided emission, then light emission from multiple directions is achieved, but the number of LEDs increases and cost increases
Solution Approach 1:
The patent merges multiple light emission functions into a single LED unit by incorporating multiple light-exiting windows on the housing. Instead of using multiple separate LEDs to achieve multi-directional emission, the design combines these functions into one integrated component, reducing the total number of LEDs required while maintaining or expanding light-emitting angle.
Solution Approach 2:
The housing acts as an intermediary component that receives light from the single LED chip and redirects it through multiple light-exiting windows in different directions. This mediator structure enables one LED to achieve the effect of multiple LEDs by utilizing the housing as a light guide and distribution mechanism.
3Adaptability or versatility
If multiple single-sided LEDs are used to achieve double-sided emission, then multi-directional light emission is achieved, but heat dissipation is adversely affected and service life is reduced
Solution Approach 1:
The patent combines the light guide function and heat dissipation function into a single housing structure. The housing that provides multiple light-exiting windows also serves as a heat sink, allowing efficient heat dissipation from the LED chip. This integration ensures that multi-directional light emission does not compromise heat management, thereby maintaining or improving service life.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously performs light guidance, heat dissipation, and mechanical protection. By making the housing serve multiple purposes, the design achieves multi-directional light emission without adding separate components that would generate additional heat, thus preserving reliable heat dissipation and extending service life.
4Ease of manufacture
If light emitted from LED chip is reflected and absorbed many times, then single-sided emission is achieved, but light emission efficiency is reduced
Solution Approach 1:
The patent changes the light emission pattern from single-direction to multi-direction by adding light-exiting windows on multiple surfaces. This allows light to exit the housing more directly through multiple paths rather than being reflected and absorbed repeatedly within a single-direction structure, significantly improving light emission efficiency while maintaining manufacturing simplicity.

AI summary
The invention discloses a LED support comprising an opaque housing. A mounting face for placing at least one LED chip is provided inside the housing. At least two light-exiting windows are provided on the housing so as to allow light emitted from the LED chip to emit outwards from the housing therethrough. The LED support enables a LED assembled with the LED support to emit light from at least two sides, thus light-emitting angle of LED is enlarged, and thereby application range of LED is widened. Meanwhile, with such LED support, the number of the light-exiting windows of the LED comprising the LED support is increased, thus the times by which light from the LED chip mounted on the LED support is reflected inside the LED support is decreased, and thereby light emission efficiency is improved significantly.
