Solid state illumination devices including spatially-extended light sources and reflectors
A luminaire module delivers light with a beam angle of α. The luminaire module includes a light emitting module and a reflector positioned symmetrically about an axis. Light produced by the light emitting module exits the light emitting module from one or more spatially-extended light emitting portions. The light emitting portion(s) is (are) fully contained within a spatially extended notional design envelope which is used to guide the design of reflector and its corresponding reflective surface, such that when any light exiting the light emitting portions through the design envelope strikes the reflective surface of the reflector, the light does not return to the source and escapes from the luminaire module within a beam angle α, with no more than a single reflection from a reflector.
Lens and lighting device
Disclosed is a lens (100) for a lighting device (10) comprising a solid state lighting element (20), the lens comprising a light exit surface (110); a central lens portion (120) opposite said light exit surface; an inner annular reflective element (130) opposite said light exit surface and extending away from said light exit surface by a first distance (d1), said inner annular reflective element delimiting said central lens portion; and a side surface defined by an outer annular reflective element (140) opposite said light exit surface and extending away from said light exit surface by a second distance (d2) that is larger than the first distance such that the outer annular reflective element extends beyond the inner annular reflective element. A lighting device such as a light bulb including such as lens is also disclosed.

Solid State Lamp Using Light Emitting Strips
A solid state lamp includes a connector and a bulb portion with multiple strips.
ILLUMINATION DEVICE
An illumination device is provided. The illumination device includes a heat sink coupled to a housing, and the heat sink includes at least one heat dissipation pin extending from an external surface of the housing. Vent holes that expose the external surface of the housing, an inside of the housing, or an inside of the illumination device to external air are formed on a side of the at least one heat dissipation pin. An upper edge of the housing and the heat sink may be spaced apart from each other, and the spaced region may include a gap that exposes the illumination device or the inside of the housing.
Reflector lamp with push-push adjustment assembly for varying a light beam angle thereof
A reflector lamp including a light source, a lens or a reflector arranged coaxially with the light source in a spaced-apart fashion, and a push-push adjustment assembly for varying a beam angle of the light beam in a push manner. The push-push adjustment assembly includes a frame coupled fixedly to the lamp, an actuator in operative connection with the lens or the reflector, wherein the actuator movably rests in the frame so that the movement of the actuator enables the lens or the reflector to slide relative to the light source thereby to provide variable axial spacing between the lens or the reflector and the light source, and a push-push latch mechanism coupled to the actuator and/or the frame to move the actuator in the frame in a push manner, and to latch the actuator in different latching positions of the frame.
Lighting device
A lighting device including: a light emitting module; a heat sink which is disposed on the light emitting module; a heat sink fan which is disposed over the heat sink; an upper case which covers the heat sink fan and the heat sink; and a lower case which is coupled to the upper case and fixes the light emitting module. A first air inlet is disposed in the lower case. A second air inlet is disposed in the upper case.

AN INTELLIGENT DIMMING RGB LED SPOTLIGHT WITH HIGH LIGHT QUALITY AND A METHOD FOR ACHIEVING THE SAME
An intelligent dimming RGB LED spotlight comprises an outer shell, a lamp base and a lampshade. A drive board connects to the lamp base and a light source board. The light source board is provided with dense ordinary-color-temperature lamp beads and RGB color-changing lamp beads, and is connected above to the lampshade corresponding to the RGB color-changing lamp beads. A method for achieving the intelligent dimming RGB LED spotlight includes the lampshade scattering the light emitted by the RGB color-changing lamp beads, so as to reduce the light intensity and make the light-emitting area larger and the emitted light more uniform, while it does not block the light emitted by the ordinary-color-temperature lamp beads, which makes the generated light spot have balanced illumination and a uniform and high-purity color in the color-changing process of a variety of colors, able to achieve the effect of AA level of GB illumination.
Color mixing optics for LED illumination device
Illumination devices with improved color mixing optics are disclosed herein for mixing the colors produced by a multi-colored LED emitter module to produce uniform color throughout the entire beam angle of the output light beam, along with smoother edges and improved center beam intensity. Embodiments disclosed herein include a unique arrangement of multi-color LEDs within an emitter module, a unique exit lens with different patterns of lenslets on opposing sides of the lens, and other associated optical features that thoroughly mix the different color components, and as such, provide uniform color across the output beam exiting the illumination device. Additional embodiments disclosed herein include a unique arrangement of photodetectors within the primary optics structure of the LED emitter module that ensure the optical feedback system properly measures the light produced by all similarly colored emission LEDs.
