Embodiment Construction

[0034] refer to figure 2 and 3 , an LED-based lamp comprising an LED-based planar Lambertian light source 8 and a light-transmissive spherical diffuser 10 . best in image 3 The LED-based planar Lambertian light source 8 is seen in the partially disassembled view of , in which the diffuser 10 exits the field of view and the LED-based planar Lambertian light source 8 enters the field of view. The LED-based planar Lambertian light source 8 includes a plurality of light emitting diode (LED) devices 12, 14, which in the illustrated embodiment include first LEDs each having a spectrum and intensity of white light mixed to exhibit a desired color temperature and CRI. LED device 12 and second LED device 14 . For example, in some embodiments, the first LED device 12 outputs white light with a green reproduction (such as may be achieved by utilizing a blue- or violet-emitting LED chip coated with a suitable "white" phosphor), and the second LED device 14 Outputting red light (such...

Abstract

A light emitting apparatus comprises: an LED-based light source; a spherical, spheroidal, ovoid, egg-shaped, or toroidal diffuser generating a Lambcrtian light intensity distribution output at any point on the diffuser surface responsive to illumination inside the diffuser: and a base including a base connector. The LED based light source, the diffuser, and the base are secured together as a unitary LED lamp installable in a lighting socket by connecting the base connector with the lighting socket. The base is operatively connected with the LED based light source in the unitary LED lamp to electrically power the LED based light source using electrical power received at the base connector.

Description

[0001] This application is a Chinese patent application with the application number 201080054756.4 and the name "light-emitting diode (LED)-based lamp" (based on the international patent application with the international application date of October 1, 2010 and the international application number PCT / US2010 / 051109 , which entered the Chinese national phase on June 1, 2012) is a divisional application. technical field [0002] The present application relates to the fields of lighting, lighting, solid-state lighting, and related fields, and in particular to a lighting device, such as a light-emitting diode (LED)-based lamp. Background technique [0003] One-piece incandescent and halogen lamps are designed as direct "plug-in" components via threaded Edison base connectors (sometimes called "Edison sockets" in the context of incandescent bulbs), bayonet type base connector (that is, a bayonet base in the case of an incandescent bulb), or other standard base connector that mate...
