Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of automatic light-supplementing camera sensor, including
Metal housing 3 and encapsulation support 6, metal housing 3 is double-layer circular cylindricality hollow-core construction, and the upper surface at metal housing 1 uniformly sets
Being equipped with aperture plate 1, the lower surface of aperture plate 1 is fitted with density sheet 8；Fix for integral type between metal housing 1 and encapsulation support 6
Designing structure, and the outward flange of encapsulation support 6 is bonded with overcoat 4, overcoat 4 defines effectively protection to the surface of encapsulation support 6,
Avoid the gouging abrasion of sensor, extend the service life of sensor；Inner chamber at metal housing 1 is additionally provided with terminal 5, terminal
5 through encapsulation support 6 two ends up and down, the quantity of terminal 5 is four, and the lower end of terminal 5 and encapsulation support 6 between away from
From design at 3cm～6cm, it is simple to the installation of sensor is changed, and is provided with light filling element 2 between four adjacent butt 5, mend
Four end angles of optical element 2 are electrically connected at the upper end of four identical terminals 5 by four contact conductors 7；At light filling element 2
Inside be additionally provided with photoconductive resistance Rs, potentiometer W, current-limiting resistance R1, coupling resistance R2, transistor Q1 and transistor Q2, brilliant
The basis set of body pipe Q1 is connected in parallel on photoconductive resistance Rs and potentiometer W, and the colelctor electrode of transistor Q1 is connected with by current-limiting resistance R1
