LED BULB FIXTURES

1. Field of Invention

This invention pertains to a light bulb fixture with built-in sensors that use new technology to control the LED bulb's on/off functions.

2. Background

In the current market, LED light bulbs primarily function by emitting light, with built-in circuits primarily serving voltage transformation to power the LEDs.

Typically, LED bulbs are manually controlled using wall switches or other external power control mechanisms. Users need to physically access control panels or wall switch locations to turn LED light bulbs on or off.

Alternatively, LED bulbs can be controlled using remote control devices, which require a receiver in the wiring to manage the circuit's on/off functions. Users must operate the remote control to turn the bulb on or off.

Another method involves using external sensors that detect nearby movement or changes in ambient light levels. These sensors automatically turn on the LED bulb when they detect movement or when the light level drops below a pre-set sensitivity threshold. Likewise, they turn off the bulb after a predetermined time. These sensors are standalone units and need to be professionally installed if users want to add sensor functionality to a room or an existing light fixture. This can be expensive and inconvenient.

In summary, current methods for controlling LED bulbs require manual intervention or the use of costly additional devices and labour.

3. Summary of Invention

In the structure of LED bulbs, as depicted in the main figure, from top to bottom, components include a Glass shade, LED Filament strip, Support Pole, LED driver circuit board, Silicon ring, and Lamp holder.

* Component 1 - Glass Shade:

The Glass shade is equipped with a transparent or coloured glass cover that safeguards the internal components, protecting them from dust and water and maintaining the internal circuit's cleanliness. The Glass shade's different colour finishes also allow for a variety of aesthetic appearances. For instance, a clear shade maximizes light output, while amber provides a warmer, more classical look, and colours like red, green, and blue offer diverse aesthetic options. The open bottom of the Glass shade forms a neck that inserts into the lamp holder, creating a sealed compartment for the internal components.

* Component 2 - LED Filament Strips:

LED Filament strips typically comprise four strips, though configurations of three, two, or a single long strip may be used based on shape requirements. These LED Filament strips consist of diodes distributed along a linear strip. When an electrical current passes through them, the strip illuminates and provides the necessary light.

* Component 3 - Support Pole:

The Support pole, whether made of glass or plastic, is used to support and secure the LED strips within the compartment. It prevents the strips from collapsing or shifting inside the compartment and also angles the strips to enhance the overall appearance.

* Component 4 - LED Driver Circuit Board:

Positioned at the bottom of the Support pole, the LED driver circuit board ensures the Support pole remains secure, preventing it from loosening and maintaining its vertical orientation. The LED driver circuit board is a vital part of the lighting system, as it transforms external electricity (typically 120-240V from the city power line) received through an external cable into the current required to illuminate the LED diodes on the LED Filament strips.

In this innovation, the circuit board incorporates sensors, including light sensors (Photodiodes) and/or microwave movement sensors. These sensors enable the LED bulb to detect changes in ambient light and motion in its environment, allowing it to turn on or off based on these changes. Consequently, LED bulbs with these integrated sensors are capable of autonomously controlling their on/off functions without requiring manual intervention or external devices. This all-in-one sensor capability is a notable advancement.

* Components 5 and 6 - Silicon Ring and Plastic Ring:

Situated between the circuit board and the lamp holder cap, the Silicon ring and Plastic ring serve to secure the circuit board in place, preventing it from shifting. Additionally, these components protect against exposure of electrons to the lamp holder cap, reducing the risk of short-circuits and creating electron isolation within the internal circuit.

* Component 7 - Lamp Holder:

The Lamp holder, located at the bottom of the structure, is typically a metal case, commonly of the Edison screw type for widespread compatibility. It consists of a large metal screw-type case affixed to an insulating material, typically made of plastic. At the bottom, there is a metal plate, separated from the top metal part by the insulating material. These metal parts allow the flow of current into the circuit board, distinguishing between Live and Neutral ends. The Lamp holder connects to the top Glass shade, completing the external structure of the LED globe.

4. Conclusion:

In an era of innovation, the conventional methods of controlling LED bulbs have been fundamentally transformed by this ground-breaking invention. LED Bulb Fixtures now incorporate an all-in-one solution for controlling their on/off functions through integrated sensors. These sensors, including light sensors (Photodiodes) and microwave movement sensors, have been seamlessly integrated into the LED driver circuit board. This innovation empowers LED bulbs to autonomously respond to changes in ambient light and motion, eliminating the need for human intervention or external devices.

Furthermore, this solution eliminates the need for costly sensor installations by certified electricians. With the sensors' components embedded within the LED bulb itself, users can effortlessly upgrade their lighting fixtures to achieve smart and convenient on/off control.

The Glass shade's diverse colour options not only enhance aesthetics but also provide flexibility in tailoring the lighting environment to match various moods and preferences, from the classic warmth of amber to the brightness of clear glass.

This invention represents a significant leap forward in LED bulb technology, simplifying and enhancing the user experience while reducing the associated costs and complexities. It embodies the spirit of technological progress, making the future of lighting a brighter and more accessible one.
