An optical system (100) comprises a first optical element (101) having one or more optical sections each having a light ingress surface (105) for receiving light from a light source and a light egress surface (106) for enabling the light to exit the first optical element Each optical section is shaped to produce an optical effect such that light beams exiting the optical section are diverging less than light beams entering the optical section. The optical system comprises a second optical element (102) being planar and having a light shaping microstructure and configured to receive light from the first optical element. The overall area of the one or more light egress surfaces of the first optical element is configured to match the area of the second optical element so that a controlled and uniform appearance is achieved on the whole area of the second optical element, while the desired low glare characteristic can be achieved.
An optical device (101) for modifying a light distribution is made of transparent material and comprises a front wall (102) constituting a front portion (103), a coupling portion (104) for connecting to a light source system, and side walls (105, 106) between the coupling portion and the front portion. The front wall is configured to let through a first part of light emitted by the light source, and the side walls are configured to let through a second part of the light. The side walls have grooves (107) that refract at least 80% of the second part of the light obliquely rearwards with respect to a direction (d) from the coupling portion to the front portion. Thus, the Optical device can be used for illuminating both a floor and a ceiling so that light emitted to unwanted directions and potentially causing glare can be kept at a low level.

An optical device includes a first optical element and a second optical element moveable with respect to the first optical element. The first optical element includes a first surface for modifying a distribution of light exiting the first optical element, and the second optical element includes a second surface facing towards the first surface and for further modifying the distribution of the light. One of the first and second surfaces includes convex areas whereas the other one of these surfaces includes concave areas. An optical effect of the optical device is changeable by moving the second optical element with respect to the first optical element in a direction parallel with the first surface. The first and second surfaces are shaped to have stepwise shape discontinuities to reduce a spatial room needed between the first and second surfaces.
An optical device comprises a first optical element (101), a second optical element (102), and a third optical element (103). The first optical element is rotatable with respect to the second optical element around a geometric optical axis (108) of the optical device, and the third optical element is linearly moveable with respect to the second optical element along the geometric optical axis. The first and second optical elements comprise surfaces (104, 105) facing towards each other for changing a width of a light distribution pattern in two perpendicular directions in response to rotating the first optical element with respect to the second optical element. The second and third optical elements comprise surfaces (106, 107) facing towards each other for changing the width of the light distribution pattern in only one direction in response to linearly moving the third optical element with respect to the second optical element.
An optical device for modifying a light distribution is made of transparent material and includes a front wall constituting a front portion, a coupling portion for connecting to a light source system, and side walls between the coupling portion and the front portion. The front wall is configured to let through a first part of light emitted by the light source, and the side walls are configured to let through a second part of the light. The side walls have grooves that refract at least 80% of the second part of the light obliquely rearwards with respect to a direction from the coupling portion to the front portion.

An optical device (201) comprises a center portion (203) and a reflector portion (204) surrounding the center portion and comprising a reflector surface (205) configured to provide total internal reflection. The center portion comprises a first lens section (206) and a second lens section (207) after the first lens section in a propagation direction of light. A projection of a light ingress surface (208) of the first lens section on a geometric plane (xy) perpendicular to a geometric line (z) through center of mass points of the first and second lens sections is smaller than a corresponding projection of a light ingress surface (210) of the second lens section on the geometric plane. As there are the two successive lens sections, a desired collimation effect can be achieved even if the lens sections are sufficiently thin from the viewpoint of manufacturing.
The present disclosure relates to systems and methods of manufacturing elongated products such as optical devices by injection moulding, wherein length of the product can be longer than the length of the cavity of the mould wherein the product is manufactured.
An optical device (201) comprises a lens (203) having a light ingress surface (204) and a light egress surface (205). The light ingress surface comprises a center ingress surface (206) and an outer ingress surface (207) that rims the center ingress surface. The center ingress surface is shaped to constitute a concave lens surface, and the outer ingress surface is shaped to constitute a convex lens surface. The concavity of the center ingress surface eliminates or at least reduces an undesired effect of a shape of a light emitting surface of a light source (202) on a light distribution pattern generated by a light fixture comprising the light source and the optical device.
An optical device comprises a first optical element (102) and a second optical element (103) moveable with respect to the first optical element. The first optical element comprises a first surface (104) for modifying a distribution of light exiting the first optical element, and the second optical element comprises a second surface (105) facing towards the first surface and for further modifying the distribution of the light. One of the first and second surfaces comprises convex areas (106) whereas the other one of these surfaces comprises concave areas (107). An optical effect of the optical device is changeable by moving the second optical element with respect to the first optical element in a direction parallel with the first surface. The first and second surfaces are shaped to have stepwise shape discontinuities (109) to reduce a spatial room needed between the first and second surfaces.

An optical device for modifying a light distribution pattern of a light source is presented. The light source radiates first light beams to a first geometric quarter-space and second light beams to a second geometric quarter-space, where the first and second quarter-spaces are defined by mutually perpendicular geometric planes one of which constitutes a boundary between the first and second geometric quarter-spaces. The optical device includes a lens-section for modifying a light distribution pattern of the first light beams and two reflector surfaces for reflecting the second light beams from the second geometric quarter-space to the first geometric quarter-space. The two reflector surfaces are successively in a direction perpendicular to the boundary between the first and second geometric quarter-spaces and make it possible that the optical device can be lower than in a case where only one reflector surface is used.
An optical device (201) comprises a lens (205) having a light ingress surface (206) and a light egress surface (207). The light ingress surface comprises one or more V-shaped projections on a center area (208) of the light ingress surface and the light ingress surface is free from corners on areas (209) outside the center area. Each V-shaped projection is shaped so that a surface penetration takes place when a light beam arrives at a side surface of the V-shaped projection and a total internal reflection takes place when the light beam arrives at the other side surface of the V-shaped projection. Thus, obliquely arriving light beams emitted by edge areas of a light emitting surface (213) of a light source (202) are mixed better with light beams emitted by other areas of the light emitting surface. Therefore, undesired color variations within a light distribution pattern are reduced.
An optical device includes a center section having a lens portion for modifying distribution of a first part of light emitted by a light source, and a peripheral section surrounding the center section and including a conical surface for modifying distribution of a second part of the light emitted by the light source. The conical surface includes ridges where total internal reflection takes place when a light beam arrives from the light source at one of side surfaces of each ridge, and surface penetration takes place when the reflected light beam arrives at the other side surface of the ridge under consideration. Thus, the conical surface acts both as a reflective surface and as a refractive surface for achieving a desired light distribution pattern.
An optical device comprises first and second optical elements (302, 303) rotatable with respect to each other around a geometric optical axis of the optical device. The first optical element comprises a first surface (304) for modifying a distribution of light exiting the first optical element, and the second optical element comprises a second surface (305) facing towards the first surface and for further modifying the distribution of the light. One of the first and second surfaces comprises convex areas whereas the other one of these surfaces comprises concave areas so that an optical effect of the optical device is changeable by rotating the first and second optical elements with respect to each other. The first and second optical elements comprise sliding surfaces (309, 310) for mechanically supporting the second optical element with respect to first optical element in radial directions perpendicular to the geometric optical axis.

ii) of the light at the light-egress surface is a polarization angle at which a p-polarized component of the light is transmitted through the light-egress surface without being reflected by the light-egress surface. Thus, unwanted reflections at the light-egress surface can be reduced and thereby unwanted scattering of light is reduced while having good transmitting efficacy.

A low-beam headlight element (600) comprises a lens (301, 401, 501) for modifying the distribution pattern of light penetrating the lens (301, 401, 501), and a reflector element (302, 502) comprising a first end having a place for a light source (307) and a second end having an opening constituting a passage for the light penetrating the lens (301, 401, 501). The thickness of the lens (301, 401, 501) is shaped to decrease more strongly towards a first edge (303) of the lens than towards an opposite second edge (204) of lens (301, 401, 501) so as to provide more refractivity on a first area (205) of the lens (301, 401, 501) abutting on the first edge (303) than on a second area (206) of the lens (301, 401, 501) abutting on the second edge (204). The refractivity on the first area (205) produces a cutoff line (311, 411, 511) in a resulting light distribution pattern. Hence, for achieving a cutoff line (311, 411, 511) meandering in a desired way, there is no need for a screen element which converts light into heat.
A light guide comprising a transparent element (201) is presented. The transparent element is made of transparent material whose refractive index is greater than unity. The transparent element comprises a first surface having light-ingress sections each suitable for receiving light and a second surface having light-egress sections. The transparent material between the light-ingress sections and the light-egress sections constitutes lenses for modifying the light distribution patterns of light received by the light-ingress sections. The transparent element comprises one or more grooves (205-208) enabling the transparent element to be divided into two or more pieces by bending the transparent element along the grooves so that each of the pieces comprises at least one of the lenses. Hence, the light guide can be easily adapted to be suitable for different illuminator systems having different number of light sources such as light emitting diodes LED.
