International Classification:

H05B 37/00

US Classification:

315185R, 315185 S, 36224902, 36224903, 36224904

Abstract:

In one embodiment, an LED lamp has a generally bulb shape. The LEDs are low power types and are encapsulated in thin, narrow, flexible strips. The LEDs are connected in series in the strips to drop a desired voltage. The strips are affixed to the outer surface of a bulb form to provide structure to the lamp. The strips are connected in parallel to a power supply, which may be housed in the lamp. Since many low power LEDs are used and are spread out over a large surface area, there is no need for a large metal heat sink. Further, the light emission is similar to that of an incandescent bulb. In other embodiment, there is no bulb form and the strips are bendable to have a variety of shapes. In another embodiment, a light sheet is bent to provide 360 degrees of light emission. Many other embodiments are described.

International Classification:

G05B 1/00

US Classification:

315312, 315307

Abstract:

A solid state lamp, such as one that can replace an incandescent light bulb, has a base portion having an electrical connector for connection to a source of power, such as an Edison-type connector for connection to the mains voltage. An AC/DC converter in the base converts the mains voltage to a suitable light emitting diode (LED) drive voltage. A plurality of receptacles on the base connects to electrodes of plug-in modules. Each plug-in module supports a plurality of low power LEDs connected in series. The strings of LEDs on different modules are connected in parallel when connected to the receptacles. The modules and base are configured to allow a user to operate the lamp with different combinations of modules to generate a desired light output from the lamp. For example, the user can recreate the lumens equivalent of a 20 W, 40 W, or 60 W bulb by using one, two, or three modules.

International Classification:

F21V 1/00

US Classification:

36221705, 36231106, 362555

Abstract:

A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

International Classification:

F21V 7/04

US Classification:

362560, 362222

Abstract:

In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.

International Classification:

H05B 37/02

US Classification:

315151, 315297

Abstract:

In a single lighting device including a large number of light-emitting elements (LEEs), the LEEs are divided into separately powered groups, and different combinations of the groups are fully energized to achieve the desired overall brightness. In some embodiments, the number of LEEs in each group has a binary relationship to the other groups. The resolution of the dimming is the brightness of the smallest group. In one example of five binary weighted groups of LEEs, 32 brightness levels can be achieved while the LEEs in the energized groups are fully ON. Thus, since there is no high frequency switching, there is substantially no power dissipation by the dimming control system, and there is limited noise or EMI created. The dimming control can be easily implemented with a logic circuit controlling a transistor switch for each group.
