Abstract
The utility model belongs to the technical field of a light emitting diode (LED) lamp optical mask and particularly relates to a scale and shell polyhedral LED lamp optical mask. The scale and shell polyhedral LED lamp optical mask is composed of a plurality of optical mask units (1) compactly arranged. The bottom face of each optical mask unit (1) is of a polygon and the upper surface of each optical mask unit (1) is of a scale and shell shape. The scale-and-shell-shaped upper surface is composed of one or more rows of scale and shell polyhedrons. Different angles are formed by the scale and shell polyhedrons and the bottom faces of the optical mask units (1) so that the scale-and-shell-shaped upper surface of the optical mask is of an arc shape. According to differences of luminous flux distribution requirements needed by practical purposes, the LED lamp optical mask is made of transparent optical glass, polycarbonate or other optical materials and the orientation angle of each surface of the optical mask is different due to different physical characteristics of materials. According to the scale and shell polyhedral LED lamp optical mask, LED lamp luminous flux can be well distributed so that reasonable distribution of the LED lamp luminous flux can be achieved and illuminating quality of an LED lamp is obviously improved.
Description
Technical field
