A light concentrating module includes an optical film having a light incident surface and a light outgoing surface facing the light incident surface, an optical wedge plate having a first surface, a second surface facing the first surface and having an angle with respect to the first surface and a third surface adjacent to the first and second surfaces, and at least one photoelectric chip disposed near the third surface. Light from a light source penetrates the optical film, and the light enters the first surface of the optical wedge by an appropriate incident angle and has total reflection between the first and second surfaces, whereby the light propagates in the optical wedge, and the light leaves the optical wedge from the third surface and is received by the photoelectric chip.

A light-emitting diode (LED) array light source includes a substrate, a meshed light-shielding layer, LED chips, and a micro-lens array. The meshed light-shielding layer includes bar-shaped light-shielding patterns intersected with one another to define openings. Each bar-shaped light-shielding pattern has a bottom surface, a top surface, and two side surfaces. A width of the top surface is smaller than that of the bottom surface. A thickness of the meshed light-shielding layer is T1. Each LED chip is exclusively located in one of the openings. The micro-lens array covers the substrate, the meshed light-shielding layer, and the LED chips and includes micro-lenses arranged in array. Each micro-lens includes a base portion and a lens portion, and is disposed corresponding to one of the openings, respectively. A vertical distance from a top portion of each micro-lens to the bottom surface is T2, and 0.278≦T1/T2≦0.833.

A locking mechanism of zoom lens which is primarily applied on zoom lens to prevent the lens group of the zoom lens to prevent the lens group of the zoom lens structure from entering into the non-zooming zone of the curvilinear slots through its zooming zone. The said locking mechanism of zoom lens mainly consists of a reverse rotation stopping block, a spring-loaded restoring slider, a stopping piece and a cap. Among them, the reverse rotation stopping block is fixed at the linear-slot-sleeve in the said zoom lens structure through the transverse slot of curvilinear-slot-sleeve and the outer sleeve in the said zoom lens structure; the cap is fixed on the said stopping block, and the said stopping piece has one end with inclined plane which can make the reverse rotation stopping block to move, only in one direction, along the transverse slots on the curvilinear-slot-sleeve and its outer sleeve and enable the lens group of the said zoom lens structure to enter into the zooming operation zone of the said curvilinear-slot-sleeve through the non-zooming operation zone of the said curvilinear-slot-sleeve to perform zooming action. Whenever one does not need to use the zoom lens, one can press the cap directly to make the inclined plane's end retreat from the transverse slot of the outer sleeve which, in sequence, makes the lens group enter the zooming operation zone of the said curvilinear slots through the non-zooming operation zone of the said curvilinear slots to attain the object of shortening the zoom lens.

A planar light source module including a light guide plate (LGP), a light source, an optical film, and a reflector is provided. The light source for emitting a light beam is disposed adjacent to the side light-incident surface, wherein the light beam enters the LGP from a side light-incident surface and leaves the LGP from a light-emergence surface in an emergence angle θ1, θ1≧70 degrees. The optical film is disposed above the LGP to collimate the light beam from the LGP. The optical film includes a prism layer module and a bonding layer module stacked alternately. The prism layer module comprises prism layers and each prism layer includes micro-prisms. The bonding layer module comprises at least one bonding layer bonded with two prism layers adjacent thereto. The refraction index of the prism layers is greater than that of the bonding layer. The reflector is disposed under the bottom surface.

A nano-structure optical insulating membrane includes a substrate, a nano-structure layer formed on the substrate, and a metal layer formed on the nano-structure layer is disclosed. Upon exposure to light, the nano-structure layer increases visible light transmission but reduces internal reflection, and the metal layer blocks infrared light and thereby provides thermal insulation. The nano-structure optical insulating membrane of the present invention enhances illumination, spares lighting equipment, saves energy, and enables users to see farther.
