Solution Overview
Problem
The need for multiple lighting devices to produce general illumination and specific wavelengths for various benefits, such as medical treatments or plant growth, is inconvenient and can alter the appearance of surroundings, making a single device capable of integrated general illumination and beneficial wavelength output desirable.
Innovation Solution
A lighting device with a first light source for general illumination and a second light source for generating specific wavelengths, integrated into a single unit, using an optical integrating cavity to combine and output light for both purposes, with control mechanisms to adjust intensity and duration for effective benefit delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple lighting devices are used to provide both general illumination and specific beneficial wavelengths, then the intensity and duration of beneficial wavelengths can be sufficient to support intended benefits, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent combines a first light source for general illumination and a second light source for beneficial wavelengths into a single integrated lighting device. The housing contains both light sources with their respective optical elements, allowing simultaneous provision of general illumination and targeted wavelength treatment without requiring multiple separate fixtures.
Solution Approach 2:
The lighting device is designed to perform multiple functions: general illumination of a space and provision of specific beneficial wavelengths for therapeutic or plant growth purposes. The controller enables the device to switch between different operational modes, making it a universal lighting solution that replaces both general lighting fixtures and specialized wavelength-specific devices.
2Illumination intensity
If multiple lighting devices are installed in a single room, then sufficient beneficial wavelength intensity can be achieved, but the installation becomes inoperable in rooms not designed for multiple devices
Solution Approach 1:
By integrating both light sources into one device, the patent eliminates the need for installing multiple separate fixtures in a room. The single housing contains all necessary components (first light source, second light source, optical elements, controller), allowing installation in standard single-fixture locations without requiring structural modifications for multiple devices.
3Illumination intensity
If multiple lighting devices are used for beneficial wavelengths, then sufficient intensity can be provided, but the appearance of surroundings is substantially altered causing patient discomfort
Solution Approach 1:
The patent uses optical elements including waveguides and diffusers to confine and direct the beneficial wavelength light from the second light source to specific treatment areas. This localized light delivery ensures that the intense beneficial wavelengths are concentrated where needed while minimizing dispersion into the general environment, thereby avoiding unwanted color casting in the surrounding space.
Solution Approach 2:
The lighting device segments the light output into distinct functional zones: general illumination light for the overall space and targeted beneficial wavelength light for specific treatment areas. The optical elements create spatial separation between these functions, allowing the beneficial wavelengths to act locally without broadly affecting the visual appearance of the entire room.
4Ease of operation
If a single lighting device provides both general illumination and beneficial wavelengths, then convenience is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple light sources, optical elements, and control systems into a single housing unit. The controller coordinates operation of both light sources, allowing the device to function as one unified system despite containing multiple components. This integration provides user convenience through single-device operation while managing internal complexity through systematic component arrangement and centralized control.

AI summary
A lighting device includes a first light source configured to generate light for illumination of a space and a second light source configured to generate light of a particular wavelength independently from the first light source. The light generated by the second light source is output at a sufficient intensity so as to reasonably expect to support an intended benefit other than illumination of the space. The first light source and the second light source are integrated into the same lighting device. The lighting device includes an optical element coupled to the first and second light sources that is configured to produce a light output of the lighting device. The lighting device outputs the light for illumination of the space and the light of the particular wavelength for the other intended benefit from the second light source via the same output of the lighting device.
