Description
Technical field
The utility model relates to infrared and safety-security area, particularly a kind of infrared LED lamp pearl for security protection and a kind of infrared light board for security protection.
Background technology
Along with the development of technology, improving constantly of living standard, safety-protection system has become indispensable part in people's daily life, and such as closed monitor system, guard against theft and alarm system, community card system, infrared perimeter alarm system etc. all belong to safety-protection system.
According to the difference of operation principle, safety-protection system can be divided into again infrared, microwave, laser, sound-detection etc. classification.Wherein, infrared security system is comparatively ripe technically, also occupies the status of outbalance at whole safety-security area.In infrared security system, infrared camera is again one of the most common equipment.
As everyone knows, infrared camera is used to absorb image, and the quality of illuminating effect directly will have influence on pickup quality, and then affect the effect of security protection.Therefore, the illuminator (being generally infrared LED light source) in infrared camera just seems especially important.But, be mounted in infrared image pickup device just because of this LED illumination System, to its design and development compared with common LED illumination System (referring to White-light LED illumination), there is a world of difference.The major function of common LED illuminator is thrown light on exactly, and the impact by extraneous factor during design is less; And Infrared LED illumination system will be subject to many restrictions of whole infrared equipment, the space of innovation is comparatively narrow: the input voltage as infrared camera is about 12V, and this just makes the voltage that can be supplied to LED chip also be this numerical value; For another example in order to adapt to security protection needs, the structure of infrared camera is all comparatively small and exquisite, and keep for the space of LED illumination System also very narrow, the size design of circuit board and heat dissipation problem are more outstanding.This difference causes the mature technology in a large amount of common white light LED illumination System can not be grafted directly in security protection infrared regime.
At present, the infrared light board structure for safety-security area of main flow is on the market: on pcb board, install two lamp pearls, be respectively provided with again an infrared LED chip in each lamp pearl, outside is covered and established an optical lens.The defect of this prior art is obvious: first, input voltage due to infrared equipment is 12V, and the operating voltage of single infrared LED chip is 1.5-2.2V, two total voltages be added together are also only 3-4.4V, therefore need extra a whole set of step-down up-flow circuit of increase, make whole wiring board very complicated, not only drawn high cost, also make radiating effect be deteriorated; Secondly, only have a LED chip in single lamp pearl in prior art, cause strong edge in the middle of light energy weak, optical lens must be selected frosted or shine the light energy that line process just can make to export even, and this obviously can the output energy of loss light; Again, what drive circuit of the prior art adopted is switch mode constant current circuit, and cost is relatively high; Finally, because prior art uses LED chip quantity few, in order to meet the needs of infrared shooting, just must add high-power, this can make the heat of LED sharply increase.
