Various embodiments may relate to a lens for a lighting assembly. The lens includes a bottom surface and an outer surface extending upwardly from the bottom surface, wherein the bottom surface includes an incident surface and the outer surface includes emergent surfaces, wherein the outer surface includes at least one first surface unit that includes a light adjusting surface and an emergent surface, the light adjusting surface receives at least one part of light beams from the incident surface and adjusts the light beams to the emergent surface to emerge through the emergent surface, and emergent light beams are converged at focus.

Lens and lighting device

Various embodiments may relate to a lens for a lighting assembly. The lens includes a bottom surface, a top surface and a side surface joining the bottom surface and the top surface. The bottom surface includes an incident surface, and the top surface includes an emergent surface, wherein the side surface includes a first side surface part and a second side surface part arranged in sequence in a direction from the top surface to the bottom surface, and the first side surface part and the second side surface part are defined by different curved surfaces and both are configured as reflection surfaces.

Lens and LED retrofit lamp

An LED lighting assembly may include a printed circuit board with an LED chip, and a heat sink thermally conducted with the printed circuit board, wherein the LED lighting assembly further comprises a light guide body configured as a bulb, the light guide body having an end surface as a light incidence surface of light from the LED chip, an outer surface as a light emergent surface and an inner surface, wherein the inner surface is structured so as to form a reflecting surface, reflecting at least part of light from the end surface to the outer surface.

LED lighting assembly and an LED retrofit lamp having the LED lighting assembly

An illuminating device includes a housing, a light-emitting assembly and a driver, wherein the housing includes a first and second cavity and a partition plate, wherein an open end in the first and second cavity may accommodate the light-emitting assembly and the driver, respectively. A lens and a driver housing further respectively mounted thereon wherein the lens and driver housing includes a first supporting leg and a second supporting leg, respectively. The second supporting leg is engaged with a first stop portion formed on an inner wall of the housing, wherein the first supporting leg extends in a through hole in the partition plate to move between a first and a second position deviating circumferentially from the first position, the first supporting leg is locked at the first position between the partition plate and a second stop portion formed in an inner wall of the housing.
