Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AR111 and AR70 LED lamps have beam angles of at least 24°, limiting their ability to generate smaller aperture beams and causing glare issues.
Innovation Solution
A narrow beam LED lamp design with a floating deflector that reduces glare by reflecting light closer to the light source, achieving an opening angle of 6° to 7°, featuring a smooth transition between the body and reflector with a continuous geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional AR lamp design is used, then the lamp structure is simple and easy to manufacture, but the beam angle is at least 24° and glare cannot be minimized
Solution Approach 1:
The lamp is divided into distinct functional components: a reflector for light collection, a deflector for beam shaping, and a lens for final beam formation. This segmentation allows each component to be optimized independently for its specific function while maintaining overall manufacturing simplicity
Solution Approach 2:
A deflector is introduced as an intermediary element between the reflector and the light source. This deflector intercepts light before it reaches the observer, redirecting it through the lens to form a narrow beam, thereby eliminating glare while maintaining a simple overall structure
2Illumination intensity
If the beam angle is reduced to 6°-7°, then concentrated light is achieved in a given location, but the lamp design becomes more complex
Solution Approach 1:
The components are nested within each other: the deflector is positioned within the reflector cavity, and the lens is integrated with the deflector assembly. This nested arrangement achieves the complex function of narrow beam formation (6°-7°) while minimizing the overall spatial footprint and simplifying the external appearance of the lamp
3Object-generated harmful factors
If the LED is hidden to reduce glare, then glare is reduced, but the beam angle cannot be reduced below 24°
Solution Approach 1:
The deflector serves as a mediator that allows the LED to remain hidden (reducing glare) while still enabling narrow beam formation. The deflector captures light from the hidden LED and redirects it through the lens, decoupling the glare reduction function from the beam angle control function
4Object-generated harmful factors
If a floating deflector is added to minimize glare, then glare is reduced, but the device complexity increases
Solution Approach 1:
The deflector is merged with the lens assembly, forming an integrated optical component. This combination reduces the number of separate parts while maintaining the glare-minimizing function of the deflector and the beam-shaping function of the lens, thereby adding minimal complexity while achieving the desired optical performance

AI summary
The present invention relates to a narrow beam LED lamp with a floating deflector, comprising an LED lamp having a body (10) and a reflector (20) of models AR111 and AR70, with a narrow beam of between 6° and 7°, and a floating deflector (30) to reduce glare. This novel structural arrangement makes it possible to reduce the beam angle and send the light back to the reflector to minimize glare by means of a recessed floating deflector positioned dose to the light source, as well as having a body with a continuous geometry.
