The present invention discloses a sector light, said sector light having at least one tier including a light source assembly comprising opaque dividing elements, two or more light sources, and two or more optical lenses; wherein the light source assembly is divided into circumferential sections, each circumferential section being separated by the opaque dividing elements, and each circumferential section containing a light source and an optical lens arranged such that the optical lens collects and outwardly projects the light emitted by the light source.

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.

A lamp capable of radiating radial pattern is disclosed, comprising a base, a transparent lampshade provided with multiple outer convex lens portions on its circumferential side and an inner recesses provided between every two adjacent outer convex lens portions, and a luminous lamp assembly located between the base and the transparent lampshade and provided with multiple luminous lamp beads. Each lamp bead is arranged corresponding to each inner recess, so that light emitted by each lamp bead respectively enters the outer convex lens portion located on both sides of each corresponding inner recess and then is refracted and converged thereby to form a radiation beam located outside the transparent lampshade and gradually shrinking from the inside to the outside, thus to radiate a brightening pattern in a circumferentially radial shape, which can greatly improve the aesthetic property and also bring people a more impressive visual impact.

A light diffusing lens having a pointing angle distribution focused toward a lateral direction. The 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. 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.

Disclosed herein are lighting apparatuses that have a centered light source and at least one off-center light source. According to certain embodiments, a lighting apparatus includes a first light fixture having a first light source arranged at a first position that is centered with respect to a first optical axis of a first optic, and a second light source arranged at a second position that is off-center with respect to the first optical axis of the first optic. The first optic is configured to receive light emitted by the first light source and the second light source.

A light flux controlling member includes an incidence surface, a reflection surface, an annular groove and an emission surface. The annular groove is disposed so as not to intersect an optical path of light incident on the incidence surface, reflected by the reflection surface, and reaching the emission surface. The first annular surface is formed so that its distance from the central axis increases, from the back side to the front side, and refracts, toward the front surface, light emitted from the light emitting center of the light emitting element, and directly reaching the first annular surface. The second annular surface is formed so that its distance from the central axis increases, from the back side to the front side, and refracts, toward the front side, light emitted from the light emitting element, incident on the incidence surface, and directly reaching the second annular surface.

A robust and easy to install obstruction illuminator is herein disclosed. The obstruction illuminator features an elongated body with a first end and a second end opposing the first end. The body of the obstruction illuminator has an inner cavity, which extends between the first and second end. An artificial light source is fitted to the first end of the body and an emission lens is fitted to the second end of the body. The artificial light source is configured to emit light into the cavity towards the second end. An optical condenser element is provided into the inner cavity of the body between the artificial light source and the emission lens. The optical condenser element receives light from the artificial light source as well as condenses and directs the condensed light toward the emission lens. The emission lens refracts the light into a pattern suitable for warning about the presence of an obstacle.

A light source device includes: a substrate; a light source on the substrate, the light source emitting light in a direction away from the substrate; an optical element covering the light source on an opposite side of the light source from the substrate to control distribution of the light emitted by the light source; and a light absorption member that absorbs light, wherein the optical element has a bottom face on a substrate side thereof and a light-exiting face on an opposite side of the bottom face from the substrate, the optical element transmits the light emitted by the light source so that the transmitted light exits the optical element through the light-exiting face, and the light absorption member is disposed between the substrate and the bottom face.

Proposed in the present disclosure is a dust scanner allowing various foreign substances existing on a floor to be clearly identified in a field of view of a cleaner user, the dust scanner including: a plurality of LED lighting components; a transmissive body including a parabolic surface having a vertical cross-section convex toward an outside, formed to be transparent, and configured to transmit light beams emitted from the LED lighting components located at an inside thereof to an outside; and blocking plates each closing and sealing a top end and a bottom end between the LED lighting components and the transmissive body, wherein each of the LED lighting components is disposed at a focal point of the parabolic surface, whereby the light beams transmitted to the parabolic surface are projected in parallel to a floor without spreading up and down.

Examples of the present disclosure provide a light distribution element, a light source module and a lamp, the light distribution element includes a light entry surface, a first light exit surface and a second light exit surface, the first light exit surface is configured to receive part of light entering the light entry surface and emit the part of the light entering the light entry surface; the second light exit surface is a reflective surface, and the second light exit surface is configured to receive part of the light entering the light entry surface and reflect the part of the light entering the light entry surface; and a direction of the light emitted from the second light exit surface is different from a direction of the light emitted from the first light exit surface, it can be used for key lighting and lighting ceiling areas respectively.
