Abstract: Disclosed is an optical structure, including a light source plate and a lens corresponding to the light source plate, where the light source plate is provided with outer-ring light sources, and inner-ring light sources are provided on an inner side of the outer-ring light sources; the lens includes a first lens portion provided opposite to the outer-ring light sources and a second lens portion provided opposite to the inner-ring light sources, and light-emitting angles of the first lens portion and the second lens portion are different; the optical structure further includes a dimming control circuit connected to the light source plate. A current ratio between the outer-ring light source and the inner-ring light source is adjusted through the dimming control circuit to adjust the light-emitting angle.

Abstract: Disclosed is a wall lamp with quick installation and an adjustable angle, including a housing. A driving member is installed inside the housing; an installation base is connected to a back side of the housing; an arc-shaped cavity is disposed at a lower end of a front side of the housing; a lamp body is connected inside the arc-shaped cavity; the lamp body includes a radiator; a light source board is installed inside the radiator; a lens is connected to a front side of the radiator; two connecting pillars are connected to a back side of the radiator; adjusting slots corresponding to the connecting pillars are disposed in the arc-shaped cavity; and end portions of the connecting pillars pass through the adjusting slots and are then connected to friction blocks.

Abstract: A lamp including a lamp body, a light source plate provided in the lamp body and having a plurality of LED lamp beads; a lens plate provided above the light source plate and having several rows of dimming lenses; a surface cover located above the lens plate and connected to the lamp body; and adjustment knobs configured to adjust a position of the lens. The lens plate may be moved by rotating the adjustment knobs so that the position of the dimming lenses relative to the LED lamp beads is changed, thereby adjusting the light-emitting angle of the lamp.

Abstract: A high bay light with linkage adjustment of an angle of modules is disclosed, including a mounting shaft and a plurality of linkage lamp bodies in an annular array, where a mounting member is connected to a top of the mounting shaft, and a rotating shaft is connected to an inner end of the linkage lamp body; a plurality of rotating grooves are arranged on a circumference of a lower end of the mounting shaft, and the plurality of linkage lamp bodies are hinged to the mounting shaft through the cooperation between the rotating shafts and the rotating grooves; a linkage cover is slideably provided outside the mounting shaft, and an outer side of an upper end of the linkage lamp body is connected to the linkage cover through a connecting shaft.

Abstract: Disclosed is a method for adjusting a light-emitting angle of a high bay light without light loss, including the steps of: determining a light distribution of a light source; iteratively calculating a surface shape of a polarizing lens according to a change in a light-emitting angle of the light source, where the optical surface shape may reach a designed light-emitting angle according to theoretical calculation, and the light distribution is uniform; symmetrically mounting a plurality of polarizing lenses having the surface shape on the left and right above the light source; and adjusting the light-emitting angle by synchronously rotating the left-right symmetrical polarizing lenses.
