Patent No. US11852311 (titled "Broad View Headlamp") was filed by Infinity X1 Llc on May 31, 2022.
’311 is related to the field of headlamps, specifically those designed to provide hands-free lighting. Traditional headlamps typically offer a focused beam for forward illumination, but often lack adequate peripheral or downward lighting. This limitation requires users to constantly adjust their head position to illuminate different areas of interest. The patent addresses the need for a headlamp that offers a combination of forward, peripheral, and downward lighting options to enhance overall visibility.
The underlying idea behind ’311 is to create a headlamp with multiple light sources, each optimized for a specific direction, and a control system to selectively activate these sources. This allows the user to customize the lighting pattern based on their needs. The key inventive insight is the combination of multiple LEDs, each with its own lens and reflector , to create distinct, directed beams that, when combined, offer a significantly wider field of illumination than traditional headlamps.
The claims of ’311 focus on a headlamp comprising multiple light sources, each with a dedicated LED, lens, and reflector, to illuminate distinct areas. Claim 1 emphasizes the ability to selectively activate these light sources in various modes to create a total combined view area wider than any single light source could achieve. Claim 11 focuses on adjusting the light spread based on proximity, and Claim 16 focuses on adjusting power consumption based on voltage.
In practice, the headlamp utilizes multiple lighting compartments within its housing, each containing one or more LEDs, reflectors, and optical lenses. These components work together to direct light to specific areas, such as forward, peripheral, or downward. A lighting control module, operated by multifunctional switches, allows the user to select from various lighting modes, activating different combinations of light sources to achieve the desired illumination pattern. The housing is designed to be water-resistant or waterproof, ensuring reliable operation in various environmental conditions.
Unlike traditional headlamps that offer limited beam direction and wide-angle headlamps that lack focused lighting and selective activation, ’311 provides a versatile solution. The use of individual lenses and reflectors for each LED allows for precise control over the direction and spread of light. The ability to selectively activate different light sources enables the user to tailor the lighting to their specific needs, whether it's focused forward illumination, wide peripheral vision, or downward lighting for close-up tasks. This customizable lighting distinguishes it from prior art.
In the early 2020s when ’311 was filed, headlamps typically used a combination of spot and flood beams for forward illumination. At a time when such systems commonly relied on simple switching mechanisms to control light modes, hardware or software constraints made complex control schemes non-trivial.
The examiner approved the claims because the prior art did not teach or suggest a headlamp with: (1) a first light source (LED, lens, reflector) illuminating a first fixed direction, a second light source (LED, lens, reflector) illuminating a second fixed direction, and a control module selectively activating the light sources to create a combined view area wider than either individual view area; (2) a lighting control module selecting a mode based on a switch, a proximity sensor sensing distance, and the control module adjusting light spread based on distance; and (3) a control module selecting a mode based on a switch, a voltage sensor sensing power source voltage, and the control module adjusting power consumption based on voltage.
This patent contains 20 claims, with independent claims 1, 11, and 16. The independent claims generally focus on a headlamp with multiple light sources and lighting modes, a headlamp with a proximity sensor that adjusts light spread, and a headlamp with a voltage sensor that adjusts power consumption. The dependent claims generally elaborate on the features and configurations described in the independent claims, such as specific light source arrangements, lighting modes, sensor types, and power source configurations.
