Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems face challenges in conveniently controlling light attributes, such as color temperature, using external and lamp body switches, especially when multiple lighting devices need to be set or switched simultaneously.
Innovation Solution
The proposed solution involves an apparatus with an indicator and a control unit that processes first and second switching signals from external and lamp body switches, respectively, allowing users to switch light attributes in a stored table or to specific settings, enabling flexible control of light attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the switch is located on the main body of the lighting device, then the lighting device can be controlled directly, but it is inconvenient for users to switch light attributes when the device is mounted in hard-to-reach locations
Solution Approach 1:
The patent introduces a communication module as an intermediary between the switch and the control unit. The switch sends switching signals through the communication module, which transmits them to the control unit for processing. This mediator enables remote control capability without requiring direct physical access to the lighting device, resolving the contradiction between ease of operation and device complexity.
2Ease of operation
If the switch is located on a wall outside the lighting device, then remote control is enabled, but it becomes inconvenient to quickly set multiple lighting devices to desired light attributes in batch
Solution Approach 1:
The control unit is designed with universal functionality to handle multiple types of switching signals from different switches. It can process signals from individual wall switches as well as recognize batch control commands. The control unit stores light attribute tables and can apply settings across multiple devices simultaneously, enabling both remote control and efficient batch configuration operations.
3Adaptability or versatility
If a lighting device has two switches for switching light attribute located respectively on the wall and on the main body, then control options are increased, but the two switches cannot be switched freely when the main body switch is not in a specific switching gear
Solution Approach 1:
The control unit dynamically adjusts its response to switching signals based on the current state and signal type. When receiving a switching signal from either the wall switch or the main body switch, the control unit determines the appropriate action by analyzing the signal characteristics and current operational state. This dynamic processing enables both switches to operate freely and independently without requiring specific gear positions, achieving full interoperability while maintaining control flexibility.

AI summary
Provided is a method and apparatus for controlling light attributes of a lighting device, and a lighting system and includes an indicator that receives an input, and sends to a control unit, a signal for switching light attribute of the lighting device; and the control unit determines whether a first switching signal or a second switching signal from the indicator is received during a light emission period after the lighting device is powered on, and if it is determined that the first switching signal is received, switching a current light attribute to another light attribute, or if it is determined that the second switching signal is received, switching the current light attribute to a light attribute indicated by the second switching signal such that when a specific light attribute is indicated by the second switching signal, the light attribute can still be adjusted with the first switching signal.
