  • Patent number: 10527239
    Abstract: Apparatus and associated methods relate to an LED-based lighting element configured to emulate a glass-bulb filament light. The lighting element has a diffuser between an LED and a transparent lens. The LED emits light of a predetermined color in an emission pattern having a preferential direction of emission. The diffuser receives the light emitted according to the emission pattern and scatters the received light according to a diffusion pattern, thereby reducing the light projected in the preferential direction. The diffuser has an absorption coefficient that is substantially constant throughout the visible spectrum so as not to substantially change the predetermined color of the emitted light as it is scattered by the diffuser. The transparent lens is configured to receive the light scattered by the diffuser and to transmit the received light therethrough.

    Abstract: Embodiments of a lamp that utilizes a reflector and a light source with light-emitting diode (LED) devices to generate an optical intensity distribution substantially similar to that of a conventional incandescent light bulb. These embodiments utilize an operation configuration with parameters that define relationships between components of the lamp to generate the optical intensity distribution. These parameters can, in one example, set out the position of the reflector relative to the light source as well as the ratio between dimensions of the reflector and the light source. In one embodiment, the reflector is in position relative to the light source to form a blocking area proximate the light source that defines a part of the lamp that does not diffuse light.

    Abstract: A light-guiding cover includes a light input surface defining a central axis and a light output surface. The light-guiding cover has a reflecting portion formed therein and substantially symmetrical about the central axis. The reflecting portion surrounding the central axis has an outer reflecting surface and an inner reflecting surface. The light input surface is defined into two regions, an inner region and an outer region, by the reflecting portion. The outer reflecting surface of the reflecting portion is arranged away from the central axis, the inner reflecting surface of the reflecting portion is arranged near to the central axis. Thus, the light-guiding cover of the instant disclosure can guide the light beams emanated from a LED to travel in certain optical paths and provide uniformly distributed lighting. Moreover, the instant disclosure also provides an illumination device having the light-guiding cover that can omni-directionally illuminate.

    Abstract: An optical device for a semiconductor based lamp comprises a semiconductor based light-emitting device and a light-redirecting member. The light-redirecting member has a reflective surface that redirects at least some of the light emitted from the semiconductor-based light-emitting device ambiently, away from the lamp, and into the surrounding environment in divergent lateral and at least partially downward directions, without further reflection. A frosted semi-transparent cover encloses the light-emitting device and light-redirecting member. A gap between the semi-transparent cover and an outer edge of the light-redirecting member passes some of the light emitted from the semiconductor-based light-emitting device upwardly into a surrounding environment.
