A vehicle headlamp structure free of reflective internal elements includes a lens and a light source. The lens includes a light emitting surface, a bottom surface, and a connecting surface. The light emitting surface is flat and the bottom surface includes at least one depression in the bottom surface to form at least one light incident structure. The at least one light incident structure includes a first light incident surface. The connecting surface is composed of a plurality of curved surfaces each with a different radius of curvature. The light source is substantially accommodated within the light incident structure and emits light through the first light incident surface to form an elliptical beam.

Lens and vehicle headlamp structure

A projection lens on a vehicle headlight includes a light incident surface and a light emitting surface facing away from the light incident surface. The light emitting surface includes a diffusing surface and a rough surface. A number of strips protrude from the diffusing surface. The strips are parallel to each other and have curved cross sections, and are configured for diffusing the light passing through the diffusing surface. The rough surface is positioned above and connected to the diffusing surface to form a horizontal connecting line, thereby allowing the rough surface to scatter the light passing through the rough surface in all directions.

Projection lens and vehicle headlamp having the same

A lighting structure includes a light source; a first lens; and a second lens. The second lens is located between the light source and the first lens. An angle between an optical axis of the first lens and an optical axis of the second lens is not more than 90 degrees. The light emitted from the light source which is not taken and refracted by the first lens is taken and refracted by the second lens.

Lighting structure

The present disclosure relates to a lens. The lens includes a bottom surface, a top surface, and a side surface. The top surface is opposite to the bottom surface. The center of the bottom surface is recessed towards the top surface to form a light incident groove. The top surface is recessed towards the bottom surface to form a light-emitting groove. The side surface is connected between the bottom surface and the top surface. The side surface defines a microstructure, and the side surface is fully covered by the microstructure.

Lens and light-emitting device employing same

The present disclosure relates to a lens. The lens includes a bottom surface, a top surface, and a side surface. The side surface is connected to the bottom surface and the top surface, and between the top surface and the bottom surface. The center of the bottom surface is recessed towards the top surface, and forms a groove. The top surface is recessed towards the bottom surface, and the top surface is concave. The groove includes a top incident surface and a side incident surface. The side incident surface is connected to the top incident surface and the bottom surface. Some micro-structures are set on the top incident surface and form a rough surface. Some reflective films are set on the side incident surface. The present disclosure also relates to a light-emitting device employing the lens.

An optical lens for an LED includes an upper portion defining a light extraction face, a lower portion and an annular flange between the upper and lower portions. The lower portion has a wall section defining a cavity for receiving the LED therein, and a curved lateral side. A lateral light generated by the LED and running against the curved lateral side has at least a part being refracted or reflected thereby to run through the light extraction face of the optical lens.

Optical lens for light emitting diode device

The disclosure relates to a lens, the lens includes a bottom surface and a light emergent surface relative to the bottom surface, the bottom surface defines a recess configured to receive a light source. The lens further includes a light incident surface opposite to the recess, the light incident surface faces away from the light emergent surface. The light incident surface is formed by a number of ring-shaped curved surfaces connected to each other one by one. The disclosure also relates to a light emitting device using the same.
