Abstract
An adjustable light supplementing lens module group for an infrared night inspection security system is disclosed. An LED light source is arranged on the central section of a pedestal, and a lens is arranged before the LED light source. The lens is fixed on a sliding member with the outer edge of the lens cooperating with a press ring, and the sliding member is embedded in a helical groove member which is fixed on the pedestal through screws. A gear member is sleeved on the helical groove member, and a plurality of helical grooves are arranged on the sidewall of the helical groove member. A plurality of screws are arranged on the side wall of the sliding member corresponding to the helical grooves, and the threaded sections of the screws are threaded in the screwed holes of the sliding member. The polished rod sections of the screw are embedded in slots in the inner wall of the gear member after passing through the helical groove. The adjustable light supplementing lens module group is greater in angle variation and enables light modulation in a larger scope for different light sources. A plastic aspheric surface is employed, which realizes condensation with smaller angle and monitoring in a longer distance. Luminous energy is concentrated in an effective area, and ineffective light is less. The adjustable light supplementing lens module group is lighter and cheaper, has wider light modulation scope, and realizes continuous change from small angle to wide angle. Light spot have no obvious defects.
Description
Technical field
The utility model relates to a kind of infrared light filling camera lens module, specifically relates to a kind of adjustable supplementary lighting camera lens module for the infrared night vision safety-protection system.
Background technology
Along with the raising of people's awareness of safety, the infrared night vision safety-protection system has obtained fast development in recent years.Take precautions against monitoring because the emphasis of security protection is night safe, the infrared photography monitoring becomes the indispensable function of supervisory system, however night infrared light very little, therefore need infrared lamp to come light filling.Infrared light filling system has two kinds of structures to realize usually, a kind of is different optical angle specification lens combination integrator, the camera lens of the corresponding respective focal of the light filling of respective angles, as the corresponding long burnt section monitoring of low-angle light filling, the corresponding short burnt section monitoring of wide-angle light filling, Jiao's section monitoring in the middle equal angles light filling correspondence, but owing to be the great-jump-forward variation from the low-angle to the wide-angle, some burnt section of monitoring camera lens with zoom is not to mate very much; Another structure is that angle changes light filling continuously, can realize coupling fully with the burnt section that zoom is monitored camera lens, but the design of light filling lens construction is very unreasonable, camera lens takes place easily move retardance, even be stuck.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical matters, and a kind of adjustable supplementary lighting camera lens module for the infrared night vision safety-protection system is provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of adjustable supplementary lighting camera lens module for the infrared night vision safety-protection system, comprise base, the base middle part arranges led light source, the led light source front is provided with lens, but described lens are arranged in the drive lens front and back position continually varying mechanism, concrete structure is that lens are fixed on the sliding part through pressure ring fit lens extension limit, sliding part is embedded in the spiral slotware, the spiral slotware is fixed on the base through screw, spiral slotware overcoat is provided with gear member, offer some helicla flutes on the sidewall of spiral slotware, corresponding sidewall at sliding part with helicla flute is provided with several screw rods, the screw flight section is screwed in the threaded hole of sliding part, and the polished rod section of screw rod is passed in the draw-in groove that helicla flute is embedded in the gear member inwall.
As preferably, offer 2～4 helicla flutes on the sidewall of described spiral slotware.
As preferably, the helicla flute of described spiral slotware adopts right hand helix, and the equal diameters of spiral fluted width and screw rod polished rod section.
As preferably, described base, spiral slotware, sliding part and pressure ring adopt the high reflectance optical resin material to make, and so both can improve the light emission rate of assembly integral body, also can save cost; Base, spiral slotware, sliding part, pressure ring and gear member color can be white, red or other colors, with the reflectivity on increase lens barrel surface, thus the light extraction efficiency of raising total system.
As preferably, described lens adopt aspheric surface one chip lens, can save cost like this when simplifying the system optics structure.
During use, the ring tooth of driving mechanism driven wheel spare base portion, when gear member rotates, move along helicla flute through draw-in groove pulling screw rod, screw rod drives sliding part and rotates in the spiral slotware and move forward and backward, and then be fixed on the sliding part lens also just away from or near the led light source at base middle part, realize that angle changes light filling continuously, can realize coupling fully with the burnt section that zoom is monitored camera lens.Beneficial effect is: angle changes bigger, can realize wider light modulation at different light sources; Adopt plastic aspherical element, more traditional glass sphere can be realized more low-angle optically focused, realizes the monitoring of farther distance; Luminous energy more concentrates on the effective coverage, invalid light still less, weight is lighter, cost is lower, dimming scope is bigger, changes the hot spot no significant defect from the low-angle to the wide-angle continuously.
