Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for collecting and transmitting sunlight suffer from significant losses due to diffused reflection and heat absorption, leading to inefficient transmission of concentrated light to remote locations, with current technologies like Fresnel lenses and convex lenses experiencing high transmission losses and chromatic aberration.
Innovation Solution
A paraboloidal reflector system with a gradient angle greater than a threshold angle is used to achieve total reflection, combined with a two-layer aspheric reflector and a light transmitting pipe system that minimizes flexure and heat absorption, allowing for efficient collection and transmission of sunlight as parallel light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a Fresnel lens or convex lens is used to collect sunlight, then light concentration is achieved, but chromatic aberration and diffused reflection occur causing very bad transmitting efficiency
Solution Approach 1:
The patent replaces refractive optical elements (lenses) with reflective optical elements (paraboloidal reflectors). This substitution eliminates chromatic aberration inherent in lens-based systems while maintaining light concentration capability through geometric reflection principles.
Solution Approach 2:
The patent employs a paraboloidal (aspheric) reflector geometry to concentrate sunlight. The curved paraboloidal surface focuses parallel sunlight rays to a single focal point, achieving high light concentration while avoiding the diffused reflection problems associated with planar or spherical surfaces.
2Speed
If plane reflected light is applied to a funnel type downward reflector, then light is reflected downward, but light is radially reflected causing diffused reflection light and much transmission loss
Solution Approach 1:
The patent replaces the funnel-type (conical) reflector with a paraboloidal reflector geometry. This aspheric surface ensures that incident parallel sunlight rays are reflected as parallel rays in a controlled direction, preventing radial diffusion and minimizing transmission loss through the light pipe.
3Length of stationary object
If optical fibers are used to transmit collected sunlight, then light transmission to remote absorber is achieved, but ultraviolet and far infrared light is absorbed causing poor thermal efficiency and bending portions cause light loss
Solution Approach 1:
The patent replaces optical fiber transmission with a hollow light pipe (transmission conduit) system. This substitution eliminates the wavelength-selective absorption characteristics of optical fibers, allowing transmission of the entire solar spectrum including ultraviolet and infrared portions that would otherwise be absorbed by the fiber material.
4Loss of energy
If a complex multistage system is designed to improve transmission efficiency, then transmitting efficiency improves, but device complexity increases
Solution Approach 1:
The patent combines the light collecting function and the light transmitting function into a single integrated system. The paraboloidal reflector is directly coupled to the light pipe, eliminating the need for separate collection and transmission components and their associated alignment mechanisms, thereby reducing overall system complexity while maintaining high transmission efficiency.

AI summary
The present invention relates to a method for collecting sunlight through an image method by tracking the sun using a dish-shaped light collector or a paraboloidal light collector and, and to a method and an apparatus for transmitting high-density light as the collected sunlight to a remote place, to which the light is applied, and for generating super-high-density light by combining, in a multi-stage manner, the high-density light obtained through a plurality of light collectors. A first concaveparaboloidal reflector of a paraboloidal light collection unit can collect light, transmit the collected light to the remote place, and provide an efficient and quantitative use environment to an applied device by using a paraboloidal reflector set including: a first concave-paraboloidal mirror in which a slope of a paraboloide is provided to make a narrow width so that downward reflection is greater than or equal to 90% by an angle between an incident angle at an inner point of a paraboloidal mirror and a normal surface, the angle being larger than a critical angle, and which has an opening formed at the lower side of a central axis thereof; and a second convex-paraboloidal reflector, which has a small diameter, shares a focus of the first concave-paraboloidal mirror, and has a miniaturized shape of the first concave-paraboloidal mirror at a focal portion without an opening at a central axis thereof.
