An LED lamp, in particular a table lamp, comprises a lighting head extending about a central axis; the head comprises: a body shaped as a ring about the axis and provided with a substantially annular seat; a plurality of LEDs arranged spaced apart from one another along the seat and about the axis and supported by a printed circuit board positioned in the seat and having a face, on which the LEDs are positioned, perpendicular to the axis; and a lens positioned in front of the LEDs to close the seat; the lens consists of a monolithic piece extending about the axis and has a concave annular inlet surface, facing the LEDs, and a convex annular outlet surface, substantially aligned parallel to the axis and extending about the axis and shaped so as to generate a rotosimmetric light emission about the axis.

The present disclosure discloses a transparent lampshade used for solar lamp, comprising a transparent lampshade body, an upper side of the lampshade body is provided with an installing recess for installing a solar luminous lamp assembly, and an upper light-transmitting portion located on a circumference of the installing recess and capable of exposing the solar luminous lamp assembly and transmitting light upwardly. Through cooperation of the installing recess and the upper light-transmitting portion in the disclosure, not only the installation of the solar luminous lamp assembly but also the use effect of light transmission on the upper side can be realized, and the outstanding effect close to the full-lighting even can be achieved, thus to maximally improve lighting effect of the whole solar lamp and bring people a more impressive visual impact, thereby greatly meeting more practical needs and facilitating further innovation and development of industry.

Disclosed is a light diffusing lens having a pointing angle distribution focused toward a lateral direction. The disclosed light diffusing lens includes a light entrance part having a concave shape formed inward from a lower part of the optical diffusing lens, a reflection part having a shape which is concave inward from an upper portion of the light diffusing lens and a light exit portion defined by an outer surface of the light diffusing lens, wherein the light entrance part has a first convex surface which is convex in an optical axial direction defined by a straight line passing through the center of the light diffusing lens as the straight line goes toward the inside of the light diffusing lens.

A light-and-shadow table lamp structure includes a lamp base, a shadow projecting plate, and a lampshade. The lamp base includes at least one light-emitting element arranged on a top thereof. The shadow projecting plate is arranged above the at least one light-emitting element to correspond thereto. The shadow projecting plate is provided with a light-transmitting pattern. The lampshade is arranged on the top of the lamp base and circumferentially encloses a periphery of the at least one light-emitting element. The light-transmitting pattern is arranged to project, by means of light from the at least one light-emitting element, a shadow of the light-transmitting pattern onto an external object.

A ring flash light diffusion device includes a first converter ring configured to connect to a camera lens and a diffuser adapter. The diffuser adapter can be connected to a first end of the first converter ring. It also includes a flash ring connected to the diffuser adapter at a position along the length of the diffuser adapter and a ring flash connected to the flash ring. It further includes a light diffuser connected to the diffuser adapter such that light emitted from the ring flash passes through the light diffuser.

The light-emitting device includes a main body, a light-emitting module, and a press part located on the main body and configured to control on or off of the light-emitting module. The main body is provided with an accommodation space having the light-emitting module arranged therein. The main body includes a light guide, and light emitted by the light-emitting module is emitted outside of the main body through the light guide. The light guide includes a light exit surface and a light entrance surface. The light entrance surface is located on the circumferential inner sidewall of the accommodation space, and the light exit surface is located on the circumferential outer sidewall of the main body, and light emitted by the light-emitting module is emitted outside along a side of the main body.

A light fixture includes a light receiver, an electrically-powered light source coupled to the light receiver, and a vessel containing a liquid. The vessel is translucent such that the light from the light source radiates through the vessel. The vessel includes an outer wall and an inner wall that define an enclosed area that receives and contains the liquid. The inner wall defines an open area positioned radially inward from the enclosed area and the inner wall includes a top opening and a bottom opening such that the open area is a through-hole extending through the enclosed area. The vessel is configured such that light emitted from the light source passes through the liquid contained within the vessel.

A ruggedized, high efficiency, diffuse luminaire with a shaped lens diffuser that is composed of a semi-soft, flexible material that helps withstand damaging impacts and protects the internal electrical components. The lens diffuser may enclose one or more internal mirrors or employ an innovative Fresnel-like lens that projects light omni-directionally and that wraps around the inside of the lens for more efficient distribution of illumination and the elimination of up and down loss through re-projecting vertical losses onto the horizontal plane. The lens diffuser may incorporate a UV filtration compound molded directly into the materials composing the lens rather than applied or painted onto the surface or surfaces of the lens. The lens diffuser may incorporate two additional innovations that better enable the reduction of glare through varying the thickness of the lens diffuser, based on its relative proximity to the bulb(s) or lamp(s), and/or applying a patterning of reflective, semi-reflective or non-reflective material to the inside of the lens diffuser relative to the proximity to the illumination source to reflect away a portion of the light and thereby attain an even distribution of light across the surface of the lens without having to ensure that the lens surface is located equidistant or nearly equidistant from the lamp or lamps within the lens.

A light head for a medical device support system. The light head includes a housing base, an annular shape first lens, a housing cover, and a motion transfer member. The housing cover includes a cavity within which the annular shape first lens is rotatable about a rotation axis. The housing cover includes a second lens. The annular shape first lens and the second lens are in a light emitting path of the plurality of light emitting elements. The motion transfer member is configured to movably interact with a boss of the annular shape first lens to rotate the annular shape first lens about the rotation axis and within the cavity. A periphery of the annular shape first lens includes guide members configured to position the boss of the annular shape first lens to movably interact with the motion transfer member.

A lens, a vehicle lamp, and a corresponding vehicle, the lens including a lens portion with a touch area and an antenna portion including a flange portion, the antenna portion being electrically conductive and at least partially opposite to the touch area. When the touch area of the lens provided with the antenna portion is touched, the capacitance of a capacitor formed by the antenna portion will change.
