Abstract

An automobile clock backlight plate comprises a disk; a pointer hole is formed in the middle of the disk; a plurality of light guiding protrusions are arranged on the lower side of the disk and surround the pointer hole; a circle of edges are upwards arranged on the edge of the disk; light refraction scales are arranged on the inner sides of the edges; a plurality of positioning columns are arranged on at the position, backing to the edges, of the back side of the disk; a plurality of inserting columns are arranged on the back side of the disk; a plurality of positioning buckles are arranged on the back side of the disk; and three light guiding columns are arranged around the disk. The automobile clock backlight plate has the beneficial effects that high-brightness automobile clock backlight illumination can be achieved through a small number of lamps, illumination brightness is uniform, and light guiding uniformity is 70% or above.

Description

technical field [0001] The invention relates to an automobile clock backlight board. Background technique [0002] The instrument panel of some automobiles is provided with a separate clock panel, and the back of the clock panel should be provided with a car clock backlight panel that can emit light to indicate the time, but the existing backlight panel uses a separate transparent plate to realize the backlight indication function. Low utilization. Contents of the invention [0003] In order to overcome the deficiency of low light utilization rate of the existing car clock backlight board, the invention provides a car clock backlight board with high light utilization rate. [0004] The technical solution of the present invention to solve the technical problem is: a car clock backlight panel, including a disc, a pointer hole is provided in the middle of the disc, and several pointer holes are provided on the lower side of the disc around the pointer hole. Light guiding pr...
