Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional horticultural lighting systems generate excessive heat, require high input power, and have inefficient light distribution, leading to increased ambient temperature, reduced system life, and limited optimal light surface area.
Innovation Solution
A light panel assembly with an extruded aluminum frame featuring a heat dissipation system, a light guide layer, a light conversion film, and a diffuser layer, which disperses and modifies radiation from LEDs to provide a broad spectrum of light with reduced heat output, using passive cooling and mono-color LEDs to maintain a lower operating temperature and increase efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional horticultural lighting systems use hundreds or thousands of LEDs packed in tight arrangement to provide adequate light output, then the light output is improved, but the heat generation increases excessively requiring additional cooling systems
Solution Approach 1:
The patent introduces a light guide layer as an intermediary between the LEDs and the growth surface. This light guide receives light from a small number of LEDs and distributes it across a large area, eliminating the need for hundreds or thousands of closely-packed LEDs and thereby reducing heat generation while maintaining adequate light output
Solution Approach 2:
The invention transitions from a two-dimensional array of many LEDs to a three-dimensional light distribution system using a light guide layer that spreads light volumetrically across the growth surface, allowing fewer LEDs to illuminate a larger area effectively
2Illumination intensity
If conventional systems use high input power to achieve high light output, then the luminous flux is improved, but the power consumption and heat generation increase
Solution Approach 1:
The patent replaces the conventional approach of using many high-power LEDs with a system using fewer LEDs combined with a light guide layer and diffuser. This substitution achieves high luminous flux through efficient light distribution rather than through high power consumption alone
Solution Approach 2:
The invention changes the light distribution parameters by introducing refractive index variations through the light guide layer and diffuser, allowing light to spread efficiently across the growth surface without requiring proportional increases in input power
3Illumination intensity
If conventional fixtures produce small surface area of optimal light despite high input power, then the light concentration is improved, but the light distribution area is limited
Solution Approach 1:
The light guide layer acts as an intermediary that receives concentrated light from LEDs and redistributes it across a large surface area while maintaining optimal light concentration through controlled refraction and diffusion
Solution Approach 2:
The light guide layer serves multiple functions simultaneously: it distributes light across the surface, maintains optimal light concentration, and eliminates the need for complex multi-LED arrays, making the system universally applicable to various grow tent sizes
4Temperature
If conventional systems use fans and elaborate cooling systems to dissipate excess heat, then the temperature control is improved, but the device complexity and expense increase
Solution Approach 1:
The patent extracts the cooling requirement entirely by using a light guide layer that enables effective light distribution with minimal heat generation, eliminating the need for fans and elaborate cooling systems that would add complexity and expense
Solution Approach 2:
The invention converts the potential harm of heat generation into a benefit by using a small number of low-power LEDs with a light guide system, where the reduced heat output becomes advantageous rather than problematic
