LIGHTING DEVICE HAVING AN INTERIM OPERABLE STATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18522530 titled 'LIGHTING DEVICE HAVING AN INTERIM OPERABLE STATE

Simplified Explanation

The abstract describes a lighting device, such as an LED light source, that can operate in an interim operable state to prevent undesirable characteristics in the emitted light. The control circuit can adjust the drive current for the emitter based on measured operational characteristics.

• The lighting device can operate in an interim operable state to avoid undesirable characteristics in the emitted light.
• The control circuit can adjust the drive current for the emitter based on measured operational characteristics.

Potential Applications

The technology described in the patent application could be applied in various lighting systems where maintaining a consistent and high-quality light output is crucial. This includes applications in residential lighting, commercial lighting, automotive lighting, and outdoor lighting.

Problems Solved

This technology addresses issues such as strobing, flickering, and color shifting in the light emitted by the lighting device. By operating in an interim operable state and adjusting the drive current for the emitter, these undesirable characteristics can be avoided or minimized.

Benefits

The benefits of this technology include improved light quality, reduced eye strain, enhanced user experience, and increased energy efficiency. By preventing undesirable characteristics in the emitted light, the lighting device can provide a more consistent and reliable performance.

Potential Commercial Applications

The technology could be implemented in various commercial products such as LED light bulbs, automotive headlights, streetlights, and architectural lighting fixtures. The improved performance and reliability of the lighting devices could attract customers looking for high-quality lighting solutions.

Possible Prior Art

One possible prior art could be the use of feedback control systems in lighting devices to adjust the drive current for the emitter based on operational characteristics. Additionally, there may be patents related to preventing undesirable characteristics in the light emitted by lighting devices through operational adjustments.

How does the control circuit determine when to switch to the interim operable state?

The abstract mentions that the control circuit can determine if a measured value of a first operational characteristic is outside of a range, but it does not specify the exact criteria or thresholds used for this determination. This could vary depending on the specific implementation of the technology.

What are the specific operational characteristics that the control circuit measures to adjust the drive current for the emitter?

While the abstract mentions a first operational characteristic (e.g., forward voltage of an emitter) and a second operational characteristic (e.g., forward voltage of a detector), it does not provide a comprehensive list of all the operational characteristics that the control circuit may consider. Understanding the full range of parameters involved in the adjustment process could provide more insights into the functionality of the technology.

Original Abstract Submitted

A lighting device, such as a light-emitting diode (LED) light source, may operate in an interim operable state to avoid and/or prevent undesirable characteristics in the light emitted by the lighting device (e.g., strobing and/or flickering of a brightness of the light and/or shifting or change of a color of the light). When operating in a normal state, the control circuit may determine if a measured value of a first operational characteristic (e.g., a forward voltage of an emitter of the lighting device) is outside of a range and operate in the interim operable state if the measured value of the first operational characteristic is outside of the range. When operating in the interim operable state, the control circuit may adjust a drive current for the emitter in response to a measured value of a second operational characteristic (e.g., a forward voltage of a detector of the lighting device).
