Focusable LED Light Bulb With Internal Heat Sink Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lighting systems with adjustable focus spotlights are typically controlled from outside the body, leading to protrusions that are aesthetically unappealing and expensive, and are difficult to integrate into PAR light bulbs due to limited space, requiring separate spotlights or floodlights for different applications.
Innovation Solution
A focusable lighting system with a base body, cover body, second light sources, convex lenses, and focus controllers located inside the LED light bulb or fixture, allowing for adjustable focus from inside the bulb, enabling a seamless integration of directional spotlights to wide floodlights without external protrusions, using male and female threads, gears, and motors for remote or manual control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If focus controllers are placed outside the LED light bulb body, then focus adjustment is achievable, but the fixture becomes aesthetically unappealing with protrusions and increases device complexity
Solution Approach 1:
The focus controller is nested inside the LED light bulb body, specifically within the heat sink structure. The controller housing is positioned within the heat sink's internal cavity, allowing the focus adjustment mechanism to be integrated without external protrusions. This nesting approach maintains aesthetic appearance while enabling focus control functionality.
Solution Approach 2:
The focus controller is merged with the heat sink structure, combining two previously separate components (controller and heat dissipation system) into a single integrated unit. The controller housing forms part of the heat sink assembly, eliminating the need for separate external control mechanisms and reducing overall device complexity.
2Device complexity
If focus controllers are placed inside the LED light bulb body, then aesthetics are improved without protrusions, but space for controller components becomes limited
Solution Approach 1:
The controller is nested within the heat sink's internal cavity, utilizing the existing space within the heat dissipation structure. This allows the controller components to be housed inside the bulb body without requiring additional external space, as the heat sink's internal volume is repurposed to accommodate the controller.
Solution Approach 2:
The controller is positioned in a different spatial dimension within the heat sink structure, utilizing the internal cavity space rather than occupying the external bulb envelope. This dimensional reorganization allows both the controller and heat sink to coexist within the same overall volume without interfering with each other's functions.
3Adaptability or versatility
If separate spotlights or floodlights are used for different applications, then lighting versatility is achieved, but the quantity of light fixtures increases
Solution Approach 1:
The lighting system incorporates a movable lens or reflector mechanism that can dynamically adjust the light beam angle and distribution pattern. This dynamic adjustment capability allows a single fixture to switch between spotlight, floodlight, and intermediate patterns, replacing the need for multiple fixed-purpose light fixtures.
Solution Approach 2:
The light fixture is designed with universal functionality to perform multiple lighting tasks through a single device. The adjustable focus mechanism enables the same fixture to serve as both a spotlight and floodlight depending on the required application, eliminating the need to purchase and install separate specialized fixtures for different lighting needs.

AI summary
A focusable lighting system is provided, comprising a base body, a first light source light source, a cover body, second light sources, convex lenses, and focus controllers. The first light source is disposed on the front surface portion of the base body. The cover body has a front opening portion connected to an inside of the cover body, a rear cover portion, top and bottom edge portions provided between the front opening portion and the rear cover portion, and two side portions. Each focus controller is installed on each convex lens in the inner space portion of the cover body and configured for controlling a distance between the corresponding second light source and convex lens and providing a light beam ranging from a directional narrow focused spot light to a wide spreading flood light.
