It drives the movement of optical lens group to change position, to change the focal length of optical system, thus changes the hair of outgoing beam
Dissipate the size at angle.
Wherein, the transmitting light source is a surface launching light source comprising laser chip and be distributed in it is more on laser chip
A point light source, multiple point light sources are in multiple spot orthogonal array structure distribution；The light-emitting surface of multiple point light sources is towards target direction.
Wherein, the optical lens group includes concave-concave extender lens and biconvex condenser lens, concave-concave extender lens and biconvex
Lens are placed sequentially in the front of transmitting light source, and transmitting light source center, biconcave lens and the center of biconvex lens three are located at same
On one horizontal linear, the biconcave lens is fixed on transmitting light source and position is fixed, biconvex lens and transmission device
It is drivingly connected and it can be moved forward and backward under the drive of transmission device, to change between biconcave lens and biconvex lens
Distance.
Wherein, the transmission device can the corresponding displacement of precise motion under the control of control panel, can advance and also may be used
To retreat, and can stop moving to respective direction at restraining position.
Wherein, the position induction device can incude the origin position of biconvex lens.
The beneficial effects of the invention are as follows：Compared with prior art, the present invention provides a kind of electric variable coke light-source system,
The system by control panel control transmission device movement, and drive the back-and-forth motion of biconvex lens come change biconvex lens with
The distance between biconcave lens, thus changes the size of beam divergence angle, and then realizes electric variable coke light-source system.It can be with
According to the size of monitoring demand shift facula area, closely accomplishing big visual field, and improving brightness at a distance, to improve
The effect of monitoring.
