An AlN buffer layer (2) is formed on a sapphire substrate (1), and nitride semiconductors of an n-type AlGaN layer (3), an InGaN / GaN active layer (4) and a p-type GaN layer (5) are layered in sequence on the buffer layer (2). An n-electrode (7) is formed on a surface of the n-type AlGaN layer (3), and a p-electrode (6) is formed on the p-type GaN layer (5). The n-type AlGaN layer (3) serves as a cladding layer for confining light and carriers. The AlN buffer layer (2) is manufactured by alternately supplying an Al material and an N material at a growing temperature of 900° C. or higher.

A frame structure includes a frame body and fixing structures. The frame structure has an inner edge, an end edge and an outer edge. The fixing structures are disposed on two opposite sides of the frame body respectively, wherein each fixing structure includes a first protrusion, a second protrusion and a stopper portion. One end of the first protrusion or one end of the second protrusion connects to the inner and the end edges to form a containing cavity. The stopper portion is located inside the containing cavity and arranged in parallel to the first and the second protrusions. The lengths of the first and the second protrusions are respectively “L1” and “L2”. The overlap length between the stopper portion and the first protrusion is “α,” the overlap length between the stopper portion and the second protrusion is “b,” L1>α≧0, and L2>β≧0.

The present invention discloses a uniform light emitting lamp structure including a lamp holder, an electric connection portion and a planar portion disposed on both end surfaces of the lamp holder respectively, and the planar portion includes a circuit board electrically coupled to the electric connection portion. The lamp structure further includes an LED light source, a lamp cover and a light guide column with a refractive index n1. After the light of the LED light source is projected from an environmental medium with a refractive index n2 to the light guide column, a portion of the light is reflected from the critical plane in a direction corresponding to the lamp holder through reflections and refractions, such that the light of the LED light source is projected in the environmental medium to achieve the uniform light emitting effect.

The present invention relates to an antiglare film, which comprises a cured transparent resin layer and a type of transparent hollow particles. The hollow particles are distributed in the transparent resin layer and partially exposed therefrom. The ratio of the inner diameter to the outer diameter of the hollow particle is within a range of 0.1 to 0.9, and the ratio of the outer diameter of the hollow particle to the thickness of the transparent resin layer is within a range of 0.1 5 to 1. The hollow particle and the transparent resin layer have different refractive indexes. The hollow particles are partially exposed from the surface of the transparent resin layer, leading the antiglare film to have excellent antiglare properties.
