Abstract
The invention discloses an infrared night vision lens which comprises an optical lens and a front end cover thereof, and also comprises an infrared LED chip and a PCB (Printed Circuit Board), wherein the front end cover is provided with a PCB fixing groove, the PCB is fixed in the PCB fixing groove, and the infrared LED chip is arranged on the PCB by adopting an SMT (Surface Mounting Technology). Compared with the prior art, the invention realizes integration of a night vision lighting device and the lens, and has the advantage of small volume.
Description
Technical field
The present invention relates to optical lens, especially relate to a kind of night vision camera lens.
Background technology
In the process of position of moveing backward, owing to passing through automobile rearview mirror, driver also cannot clearly see the situation of the positive rear end of automobile, therefore, in reversing process, automobile tail object easy and rear end, parking stall bumps, especially in strange parking environment or in the parking environment of insufficient light.The camera head in automobile tail installation with night vision function can address the above problem, but existing night vision cam is used for greatly safety-security area, its camera lens and infrared light pipe adopt split pattern, and infrared light pipe is fixed on the periphery of camera lens by additional stationary installation.Therefore camera overall volume is larger.This camera lens is installed on to automobile tail, will has a strong impact on the outward appearance of automobile.
Summary of the invention
Technical matters to be solved by this invention is, a kind of night vision camera lens with infrared night viewing function is provided, and it has the advantage of small size.
The present invention solves the problems of the technologies described above by following technological means:
A kind of infrared night vision lens, comprise optical lens and front end end cover thereof, also comprise infrared LED chip and pcb board, described front end end cover is provided with pcb board pickup groove, described pcb board is fixed in described pcb board pickup groove, and described infrared LED chip is arranged on described pcb board by SMT surface mounting technology.
Compared with prior art, owing to adopting the LED chip of un-encapsulated, than adopting finished product LED lamp, more save installing space, and be fixed on the front end end cover of camera lens after directly this LED chip SMT being mounted on pcb board, realize camera lens and lighting device is integrated, thereby make camera lens self there is night vision function, compare and there is less volume with the traditional infrared camera of camera lens/infrared LED lamp split setting.Because the front end end cover rim space of camera lens is limited, therefore, technical scheme of the present invention is particularly useful for being arranged on automobile tail etc. without the scene of remote monitoring, can select small size, low power LED chip, thereby reduce the difficulty that realizes of such scheme.
For simplified structure, convenient installation, described pcb board pickup groove is the annular groove arranging around described optical lens, the structure of described pcb board is and the corresponding ring texture of described annular groove that the size of described annular groove and described pcb board is arranged so that described pcb board can be stuck between the madial wall and lateral wall of described annular groove.
Preferably, described camera lens also comprises described pcb board and LED chip is encapsulated in to the Waterproof glue line in described annular groove, covers pcb board and LED chip top, and this marine glue preferably adopts epoxy resin organism.The Waterproof glue line of this preferred version, with waterproof action, LED chip encapsulation effect and the fixedly effect of pcb board, without LED chip is carried out to independently encapsulation process, also, without pcb board fixed mechanism is independently set, has been simplified the production process of camera lens.Directly sealing on camera lens, also has better waterproof ability.
Preferably, described pcb board pickup groove bottom is provided with elastoplast layer, and described pcb board is fixed on described elastoplast layer, and the external terminal of described pcb board is through the connection of described elastoplast layer and front end end cover bottom.Elastoplast layer has waterproof effect, simultaneously because it has elasticity, thereby can play the damping protection external terminal of pcb board and the reliability being connected of outside line.
Preferably, described pcb board is PCB sheet metal or the PCB glass-fiber-plate with good heat conductive performance.
Preferably, also comprise visible LED chip, described visible LED chip is arranged on described pcb board by SMT surface mounting technology.
Preferably, also comprise photoresistance, this photoresistance is arranged on described pcb board by SMT surface mounting technology.
Accompanying drawing explanation
Fig. 1 is the vertical view of the camera lens of the specific embodiment of the invention;
Fig. 2 is the A-A line cut-open view of Fig. 1.
