    摘要： The present invention relates to an illumination device (1) having an optical-electronic light source (2) and an optical body (3) for distributing light, which optical body (3) is divided into an inner lens part (3a) and an outer reflector part (3b) which adjoins the latter towards the outside, which optical body parts (3a, b) are formed monolithically with one another, wherein the inner lens part (3a) is shaped as a Fresnel lens, that is to say a light passage face (4) of the inner lens part is divided into active edges (4a) and folding edges (4b), which Fresnel lens acts with the active edges (4a) as a collecting lens, with the result that a first part (21a) of the light which passes through the Fresnel lens via the active edges (4a) is refracted towards a main direction (5), wherein a second part (21b) of the light which passes through the Fresnel lens via the folding edges (4b) is refracted away from the main direction (5), and wherein a reflection face is provided on the outer reflector part (3b), onto which reflection face the second part (21b) of the light is incident and is reflected there and deflected with the reflection towards the main direction (5).

    摘要： A portable lighting device (100) according to the present invention includes a battery housing (102), a light source (122) supported at a first end of the battery housing (102), and a shroud (114) extending outward from the first end of the battery housing (102) circumferentially around the light source (122). The shroud (114) is preferably formed of a translucent material having a partially-reflective inner surface (120) for reflecting a portion of inncident light emitted from the light source (122) in a forward direction while allowing a portion of the incident light to be transmitted through the shroud (114) and dispersed in peripheral directions. The shroud (114) further preferably includes a diffusing outer surface (126) for diffusing the incident light that is transmitted through the shroud (114). A shroud (114) is preferably integrally formed with a collar portion (112) as used for threading the integrated head structure (110) onto the battery housing (102). Additionally, a protective lens cover that may include a collimating lens is also integrally formed in this head structure (110). Thus, the portable lighting device (100) of the present invention may be constructed with much fewer components and at a much lower cost than conventional flashlights.

    摘要： An improved optical package is disclosed which includes a light source (2), an installation socket (1), a mirror (3) and a convex lens (4), wherein at least one part of the projection of the reflection surface of the mirror (3) on its axial section is in a parabolic shape, and the axes of the mirror (3) and the convex lens (4) share the same line. The installation socket (1) can move along the axial direction of the convex lens (4) and an installation depression (11) is set at the front end of the installation socket (1), wherein the light source (2) is configured in the installation depression (11), the emitting point of the light source (2) is on the axis of the convex lens (4) and the circumference of the installation depression (11) is formed to be a reflection surface capable of reflecting the light emitting from the bottom of the light source (2). Also disclosed is a torch applying the optical package above. The optical package effectively reduces light loss and can realize long-distance illumination. Moreover, a torch installed with the disclosed optical package can realize rapid shadow conversion and avoid moving the originally-set best luminous efficiency position due to extrusion of external forces effectively.

    摘要： Disclosed in various embodiments are integrated lens and bezel systems for a flashlight or other lighting unit. Various embodiments include a housing, including a bezel portion and a body portion, a lens, wherein the lens and the bezel together comprise a single, continuous component, and a light source disposed within the housing, wherein the light source is configured to interact with the lens to provide a light beam. Some embodiments provide a mechanism for adjusting the relative positions of the light source and lens, for example to allow for focusing of the light beam. In some embodiments, the lens is continuous with just the bezel portion, whereas in other embodiments, the lens, bezel, and all or part of the body portion are formed as a single, unitary component, for instance by injection-molding or co-molding.
