Abstract

The invention discloses a light guide device and a network camera provided with the light guide device. The light guide device comprises a light guide substrate, a light source bearing part, a first through hole, and two first blind holes. The light source bearing part is used for bearing a light source and guiding the light emitted by the light source into the light guide substrate. The first through hole is adjacent to the light source bearing part and is arranged on the light guide substrate. The first through hole is used for allowing other elements to pass through. A connecting line between the first through hole and a light source bearing seat is defined as a first connecting line. The two first blind holes are symmetrically arranged on the two sides of the first connecting line. The first through hole is positioned between the two first blind holes and the light source bearing seat. The two first blind holes are positioned corresponding to the first region of the light guide substrate. The light is deflected when passing through the two first blind holes, so that the brightness of the first region is reduced. According to the technical scheme of the invention, due to the arrangement of blind holes diversified in shape and function, the brightness of regions higher in brightness is reduced, while the brightness of regions lower in brightness is improved. Therefore, the brightness difference between different regions is reduced. The light uniformity of the light guide device is improved.

Description

technical field [0001] The invention relates to a light guide device and a network camera using the same, in particular to a light guide device with high light uniformity and a network camera using the same. Background technique [0002] Please refer to figure 1 , figure 1 It is a top view of the light source assembly of the network camera in the prior art. The light source assembly 1000' in a common network camera includes a light source 100' (such as an LED) and a circular light guide plate 200'. The circular light guide plate 200' has a central hollow area 210', and four LEDs are respectively located in the central hollow area 210'. In the four corners, when the light source assembly 1000' is working, the light emitted by the LED enters the interior of the circular light guide plate 200' through the edge of the central hollow area 210', making the circular light guide plate 200' a surface light source to meet the requirements of the network camera. backlight requiremen...
