Abstract
The utility model discloses an infrared night-vision lens which comprises an optical lens, a front end cover of the optical lens, an infrared LED (light emitting diode) chip and PCBs (printed circuit boards), wherein the front end cover is provided with PCB fixing grooves; the PCBs are fixed in the PCB fixing grooves; and the infrared LED chip is arranged on one PCB by SMT (surface mount technology). Compared with the prior art, the infrared night-vision lens integrates a night-vision lighting device and the lens and has the advantage of small volume.
Description
Technical field
The utility model relates to optical lens, especially relates to a kind of night vision camera lens.
Background technology
Go in the process of position in reversing; Because through automobile rearview mirror, the driver also can't clearly see the situation of the positive rear end of automobile, therefore; Automobile tail the object easy and rear end, parking stall bumps in the reversing process, especially in strange parking environment or in the parking environment of insufficient light.At automobile tail the camera head with night vision function being installed can address the above problem; But existing night vision cam is used for safety-security area mostly; Its camera lens and infrared light pipe adopt the split pattern, and infrared light pipe is fixed on the periphery of camera lens through additional stationary installation.Therefore the camera overall volume is bigger.This camera lens is installed on automobile tail, with the outward appearance that has a strong impact on automobile.
Summary of the invention
The utility model technical matters to be solved is, a kind of night vision camera lens with infrared night vision function is provided, and it has the advantage of small size.
The utility model solves the problems of the technologies described above through following technological means:
A kind of infrared night vision camera lens; Comprise optical lens and front end end cover thereof, also comprise infrared LED chip and pcb board, said front end end cover is provided with the pcb board pickup groove; Said pcb board is fixed in the said pcb board pickup groove, and said infrared LED chip is arranged on the said pcb board through the SMT surface mounting technology.
Compared with prior art; Owing to adopt the led chip of un-encapsulated; Practice thrift installing space more than employing finished product LED lamp, and be fixed on the front end end cover of camera lens after directly being mounted on this led chip SMT on the pcb board, realize that camera lens and lighting device are integrated; Thereby make camera lens self have night vision function, have littler volume with camera lens/the traditional infrared camera of infrared LED lamp split setting is compared.Because the front end end cover rim space of camera lens is limited, therefore, the technical scheme of the utility model is particularly useful for being installed in the scene that automobile tail etc. need not remote monitoring, can select small size, low power led chip, thereby reduce the realization difficulty of such scheme.
For simplified structure; The convenient installation; The annular groove of said pcb board pickup groove for being provided with around said optical lens; The structure of said pcb board is and the corresponding ring texture of said annular groove that the size of said annular groove and said pcb board is arranged so that said pcb board can be stuck between the madial wall and lateral wall of said annular groove.
Preferably, said camera lens also comprises said pcb board and led chip is encapsulated in the Waterproof glue line in the said annular groove, covers pcb board and led chip top, and this marine glue preferably adopts the epoxy resin organism.The Waterproof glue line of this preferred version need not led chip is carried out independently encapsulation process with waterproof action, led chip encapsulation effect and the fixedly effect of pcb board, also need not the pcb board fixed mechanism independently is set, and has simplified the production process of camera lens.Directly sealing on camera lens also has better waterproof ability.
Preferably, said pcb board pickup groove bottom is provided with the elastoplast layer, and said pcb board is fixed on the said elastoplast layer, and the external terminal of said pcb board passes said elastoplast layer and is connected with the circuit of front end end cover bottom.The elastoplast layer has waterproof effect, simultaneously because it has elasticity, thereby can play the reliability that is connected that external terminal with the outside line of pcb board are protected in damping.
Preferably, said pcb board is PCB sheet metal or the PCB glass plate with good heat conductive performance.
Preferably, also comprise the visible light led chip, said visible light led chip is arranged on the said pcb board through the SMT surface mounting technology.
Preferably, also comprise photoresistance, this photoresistance is arranged on the said pcb board through the SMT surface mounting technology.
Description of drawings
Fig. 1 is the vertical view of the camera lens of the utility model specific embodiment;
Fig. 2 is the A-A line cut-open view of Fig. 1.
Embodiment
Contrast accompanying drawing and combination preferred embodiment are described further the utility model below.
Like Fig. 1, shown in 2, the infrared night vision camera lens of present embodiment mainly is made up of optical lens 1, front end end cover 2 and lighting device; Lighting device mainly is made up of infrared LED chip 31, visible light led chip 32, photoresistance 33, ring-type pcb board 34.
Front end end cover 2 is a hollow and annular, and its hollow bulb is used to hold camera lens 1; The edge of front end end cover 2 is provided with the ring-type pcb board 34 that pcb board pickup groove 21 is used for fixing lighting device; With the hollow bulb concentric annular groove 21 of the pickup groove 21 of present embodiment for being provided with around camera lens 1; The bottom of this annular groove 21 is provided with elastoplast layer 22, can regulate the irradiating angle of led chip as required through the thickness setting of groove 21 degree of depth settings and elastoplast layer 22.
The camera lens of present embodiment also comprises Waterproof glue line 35, is used for said pcb board and led chip are encapsulated in said annular groove 21, and for guaranteeing good light transmittance ability and water resistance, its material preferably adopts the epoxy resin organism.These Waterproof glue line 35 preferred vacuum casting techniques that adopt are formed at said pcb board 34 tops, cover infrared LED chip 31, visible light led chip 32 and photoresistance 33, thereby play the excellent waterproof effect.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the utility model person of ordinary skill in the field; Under the prerequisite that does not break away from the utility model design; Can also make some being equal to substitutes or obvious modification, and performance or purposes are identical, all should be regarded as belonging to the protection domain of the utility model.
