Abstract
The utility model provides a night-time vision device light guide plate, its characterized in that: the utility model discloses a night-time vision device, including night-time vision device, light guide plate top symmetry, upper portion integrated into one piece has a protruding face, the light guide plate is the piece of nearly circular column structure, the light guide plate middle part is hollow structure, the inclined plane groove has been seted up to light guide plate upper portion symmetry, upper portion integrated into one piece has the outstanding face in the light guide plate, the light guide plate is high transparent organic glass board, through increasing a LED light source point in the night-time vision device, adopts the light guide plate with light leading-in visual field, the LED lamp that can see light from the left side eye-.
Description
Technical Field
The utility model relates to an optical instrument equipment field, concretely a night-time vision device light guide plate.
Background
The night vision device is a night external sighting device with an intensifier as a core device, an infrared searchlight is not used for illuminating a target when the night vision device works, light rays reflected by the target under weak illumination are enhanced to visible images which can be sensed by human eyes on a fluorescent screen through an image intensifier to observe and aim the target, the infrared night vision device is a military night vision device which utilizes a photoelectric conversion technology and is divided into an active mode and a passive mode, the infrared searchlight is used for illuminating the target, and reflected infrared radiation is received to form images; the latter do not emit infrared radiation and rely on the infrared radiation of the target itself to form a thermal image.
The existing night vision device adopts infrared imaging, so that the light of a visual field is weak.
Disclosure of Invention
An object of the utility model is to provide a night-time vision device light guide plate through increasing a LED light source point in night-time vision device, adopts the light guide plate with the leading-in visual field of light, can see the LED lamp that is shining from the eye-shade on the left side, through the luminance of LED lamp, differentiates light gain intensity, the advantage is because on not being in the optical axis, can not have the interference to the visual field.
In order to achieve the above object, the utility model adopts the following technical scheme:
a night vision device light guide plate comprises a night vision device, a light source and a light guide plate, and is characterized in that: the night-vision device comprises a night-vision device body and is characterized in that a light source is fixed inside the edge of the right side of the night-vision device body, a light guide plate is installed in the middle of the night-vision device body, the light guide plate is a piece of a nearly circular structure, the middle of the light guide plate is of a hollow structure, inclined plane grooves are symmetrically formed in the upper portion of the light guide plate, a protruding surface is integrally formed in the upper portion of the light guide plate.
The beneficial effects of the utility model are concentrated and are embodied in:
1) the light emitted by the LED lamp is refracted by the light guide plate, the bright LED lamp can be seen from the left eye shield, and then the light gain intensity is distinguished through the brightness of the LED lamp;
2) because the light guide plate is hollow structure for the middle part, such setting can not influence the propagation of light, and the light path that LED lamp and light guide plate formed is not on the optical axis moreover, can not have the interference to the visual field.

Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a perspective view of the light guide plate of the present invention;
FIG. 3 is a back view of the light guide plate according to the present invention;
fig. 4 is a sectional view of the utility model a-a.
Detailed Description
The invention will be further elucidated with reference to the accompanying figures 1-4.
A night vision device light guide plate comprises a night vision device 1, a light source 2 and a light guide plate 3, and is characterized in that: the utility model discloses a night vision device, including night vision device 1, light guide plate 3, inclined plane groove 4, light guide plate 3, upper portion integrated into one piece have a projecting surface 5, light guide plate 3 is the high organic glass board that passes through, and the light that the LED light source sent propagates along the horizontal plane, and 4 positions of inclined plane groove offered on light guide plate upper portion form the refraction and propagate along light guide plate 3, then refract out from projecting surface 5 on light guide plate 3 and form parallel light path, and the angle of inclined plane groove 4 and projecting surface 5 is 45 degrees, and light after the refraction is not on the optical axis, can not form the influence to the visual field.
