South Carolina Patent of the Month – July 2023

EmeryAllen, LLC, based in Charleston, South Carolina, has dedicated their expertise to developing new products. This effort has culminated in the creation of the most well-rounded miniature LED lamps on the market.

LED technology has revolutionized the lighting industry, offering energy-efficient and long-lasting lighting solutions. However, the intense brightness and directional emission of traditional LED lamps can often result in uncomfortable glare and harsh lighting. In search of a solution, EmeryAllen has developed an innovative LED lamp with a high transmittance opaque diffuser, providing a non-directional photometric distribution and a more pleasing lighting experience.

The key to this breakthrough lies in the design of the light emitting apparatus. The LED lamp comprises a base portion with an electrical connector for power input and a body portion coupled to the base. Within the body portion, there is an interior cavity housing one or more LEDs, positioned below the upper circumference of the body portion. This unique arrangement ensures that the entirety of the LED(s) remains below the rim of the interior cavity, creating a visually concealed light source.

To further enhance the light diffusion and create a non-directional photometric distribution, the LED lamp incorporates a lens portion made of a diffuser material. This lens portion, coupled to the upper circumference of the body portion, scatters the directional emission of light from the LEDs, resulting in a soft and evenly distributed illumination. Importantly, when the LEDs are disengaged, the lens portion appears opaque, maintaining a sleek and elegant appearance.

The benefits of EmeryAllen’s LED lamp are not limited to aesthetics. The chip-on-board LED configuration used in the apparatus ensures a precision beam angle providing ample coverage for various lighting applications. Furthermore, the combination of the LEDs and the electronics assembly within the apparatus achieves a remarkable luminous efficiency of at least 50 lumens per watt, maximizing energy savings without compromising brightness.

The lens portion of the LED lamp is crafted from a polycarbonate material blended with light-diffusing particles. These particles, with irregular or asymmetrical shapes, effectively scatter the emitted light while maintaining high light transmission. The concentration of these particles, along with the polycarbonate matrix, achieves a haze percentage of at least 90%, guaranteeing superior light diffusion.
