Optical Module Deflection Structure for Ceiling Light Distribution
Solution Overview
Problem
Existing ceiling lights lack flexibility in lighting distribution, as they often provide uniform lighting that may not meet the desired illumination needs for different situations or uses of a space.
Innovation Solution
An optics module for ceiling lamps, comprising a lower transparent element with a deflection structure that redirects light from the side edge to the underside, and an upper element with a light steering structure to direct light from the side of the top element, allowing for adjustable light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single transparent optical element is used to cover the light source, then the structure is simple and manufacturing is easy, but the lighting distribution is uniform and lacks flexibility for different situations
Solution Approach 1:
The single optical element is divided into two separate elements: a lower optical element with a deflection structure and an upper optical element with a light-guiding structure. This segmentation allows each element to perform specific functions - the lower element creates direct light distribution while the upper element creates indirect light distribution - thereby achieving flexible lighting distribution without requiring a complex multi-component system.
Solution Approach 2:
The patent introduces adjustable components that allow the lighting distribution to be dynamically changed. The lower optical element can be adjusted to change the direction and distribution of direct light, while the upper optical element can be adjusted to modify indirect light distribution. This dynamic adjustability enables adaptation to different lighting needs and situations.
2Object-affected harmful factors
If light is directed directly downward through a simple cover, then the structure is simple, but glare is high and comfort is reduced
Solution Approach 1:
The optical system is segmented into two functional elements: the lower optical element that manages direct light and the upper optical element that manages indirect light. The lower element includes a deflection structure that redirects light to reduce glare, while the upper element provides a light-guiding structure for indirect illumination, thereby reducing overall glare without requiring an overly complex system.
Solution Approach 2:
The upper optical element acts as an intermediary between the light source and the ceiling/room. It receives light from the lower element and redirects it indirectly, serving as a mediator that softens the light distribution and reduces glare while maintaining a relatively simple overall structure.
3Adaptability or versatility
If fixed lighting distribution is used, then the structure is simple, but it cannot adapt to changing lighting needs or preferences
Solution Approach 1:
The patent incorporates adjustable components that allow the optical elements to be repositioned or reconfigured. The lower optical element with its deflection structure and the upper optical element with its light-guiding structure can both be adjusted to create different lighting distributions, enabling the system to adapt to various lighting scenarios and preferences while maintaining reasonable manufacturing simplicity.
Solution Approach 2:
The two-optical-element design provides multi-functionality: the lower element can create direct lighting for task illumination, the upper element can create indirect lighting for ambient illumination, and both can be adjusted to achieve various light distribution patterns. This universal design allows a single system to serve multiple lighting needs without requiring multiple separate fixtures.

Implementation Method 1
a deflection structure (211) which is designed to redirect light which enters through the side edge (213) so that it is emitted through the underside (214)
Implementation Method 2
a deflection structure (211) which is designed to redirect light which enters through the side edge (213) so that it is emitted through the underside (214)
Implementation Method 3
