Illuminated, decorative light objects are disclosed that provide at least one aesthetic lighting display or light show, and to a user interface for the same. A disclosed decorative light object includes a translucent housing. The housing has a bottom opening leading into a cavity. The object also includes a base assembly that covers the bottom opening of the housing. The base assembly includes a user interface. The user interface includes light show circuitry, memory for storing a plurality of light shows, switches or buttons for recalling the light shows from the memory and at least one light group comprising red, green and blue lights. The switches of the user interface are supported in the bottom opening. The light show circuitry, memory and lights are supported within the cavity. Preferably, a translucent light pipe with a roughened lambertian outer surface covers and hides the circuitry and the lights. As the light shines through the light pipe it is diffused thereby creating a warm glowing appearance.

A tube-type light-emitting diode (LED) illumination lamp is provided. The tube-type LED illumination lamp includes at least one printed circuit board on which at least one LED is placed, and a heat dissipation cover that has at least one seating surface on which the printed circuit board is mounted. The seating surface is obliquely formed such that each printed circuit board is mounted on each inclined surface. According to the present invention, since a light diffusion angle is increased by obliquely positioning the printed circuit board on which the LED is placed, illuminance quality of the tube-type LED illumination lamp can be improved.

The invention provides a sheet (1) comprising a light-transmittable resin, in which irregularities are formed on both sides (1a) and (1b) of the sheet, the average surface roughness of one side (1a) which becomes the light-entering side is from 0.2 to 5.0 μm and larger than the average surface roughness of the opposite side (1b) that becomes the light-departing side, wherein the average surface roughness of the opposite side (1b) is from 0.2 to 2.0 μm, and the surface area ratio of the one side (1a) is smaller than the surface area ratio of the opposite side (1b).

An optic film includes a body and a condensation layer. The body is formed by stacking a plurality of substrates made of different materials. By means of the different physical characteristics of the different materials, the optic film realizes excellent optic performance. Also provided is a backlight module using the optic film.

An optical substrate having a structured prismatic surface and an opposing structured lenticular surface. The structured lenticular surface includes shallow-curved lens structures. Adjacent shallow-curved lens structure may be continuous or contiguous, or separated by a constant or variable spacing. The lens structure may have a longitudinal structure with a uniform or varying cross section. The lenticular lenses may have a laterally meandering structure. Sections of adjacent straight or meandering lenticular lenses may intersect or partially or completely overlap each other. The lenticular lenses may be in the form of discontinuous lenticular segments. The lenticular segments may have regular, symmetrical shapes, or irregular, asymmetrical shapes, which may be intersecting or overlapping, and may be textured. The lens structure may be provided with isolated ripples, in the form of a single knot, or a series of knots.

A liquid crystal display, comprising: a liquid crystal display panel and a backlight module. The backlight module comprising: a reflection unit, a light emitting unit, and a compound diffusion plate structure. The light emitting unit has a plurality of light emitting components installed within the installation space of the reflection unit. The compound diffusion plate structure is placed on one side of the light emitting unit, comprising: a body unit and a printing micro diffusion unit. The body unit has a main layer, and a plurality of micro diffusion particles formed inside the body unit, allowing light to diffuse within the body unit. The printing micro diffusion unit has a plurality of convex lens units formed on a light entrance plane or a light exit plane of the body unit by means of printing.

This invention discloses a method of forming an uneven structure on a substrate. Use a hard tool to penetrate into a mold to cut a first trench and a second trench in an order on a surface of a mold, wherein the hard tool has a smoothly-curved shape such that the transverse width of each of the first trench and the second trench increases as the penetrating depth of the hard tool increases, wherein when each of the first trench and the second trench marches along a first direction, the penetrating depth of the hard tool is controlled by repeating moving the hard tool up and down to cut the mold such that the transverse width of each of the first trench and the second trench varies according to the controlled penetrating depth of the hard tool, wherein the first trench and the second trench completely overlap with each other with no space therebetween. Then, use the surface of the mold to emboss a thin film on a substrate.
