Description
Technical field
This utility model belongs to lighting technical field, especially relates to a kind of light-operated LED light compensating lamp.
Background technology
The needs broken laws and commit crime along with socio-economic development and strike, high-definition camera monitors at road or bayonet socket, and the application in terms of electronic police is more and more extensive.But, either bayonet socket monitoring or electronic police, the most all there is an important problem, it is exactly, lighting environment at night cannot meet the shooting needs of photographing unit or video camera, the image effect thus causing shooting is poor, greatly reduces image applicability in terms of post analysis, identification.
The application of light compensating lamp makes this problem be addressed, wherein the most prominent with LED light supplement lamp effect.In terms of traffic LED light supplement lamp, for illumination mode, long bright light and stroboscopic lamp can be divided into, the longest bright light good stability, light filling effect stability, is not easily susceptible to external interference, but the power supply of long bright light controls and heat dissipation problem but greatly limit the extensive of it and applies.LED light supplement lamp is under conditions of outside work, due to the impact of precipitation dust storm, it is desirable to it possesses the function of sealing, and the most long work quantity of heat production is big, and radiating effect is undesirable, greatly reduces the life-span of light compensating lamp, and it is extremely difficult to the requirement in 3 year life-span.
How to use construction volume little, connected mode simply designs, both the sealing of LED light supplement lamp and the stability of illumination effect had been can ensure that, the thermal diffusivity of light compensating lamp can be improved again, extend its life-span, always a difficult problem for illuminating industry, do not have successful story the most so far, the needs broken laws and commit crime along with socio-economic development and strike, this demand is more urgent.
Summary of the invention
The purpose of this utility model is to provide a kind of light compensating lamp of vehicle license plate in common high-definition camera identification at night motion, light compensating lamp is opened night under the control of photosensitive switch, daytime closes, save manually-operated cost, simultaneously, light compensating lamp connected mode is simple, seal, thermal diffusivity is good, is suitable for outdoor application.
The technical solution of the utility model:
A kind of light-operated LED light compensating lamp, including LED and circuit control module, is packaged in former and later two housings respectively, and the rear wall of procapsid and the antetheca of back casing are connected by support bar；Described circuit control module includes light-operated circuit plate, light sensitive diode, light-operated circuit plate electrically connects with LED, light sensitive diode electrically connects with light-operated circuit plate, described light sensitive diode is embedded on back casing lateral wall, light sensitive diode top leans out back casing surface, having a circular hole matched with light sensitive diode diameter on back casing lateral wall, use fluid sealant to be connected between described light sensitive diode and the circular hole of back casing lateral wall, described fluid sealant is positioned at inside back casing.Light sensitive diode top leans out back casing surface, and the installation site of light sensitive diode and mounting means both ensure that the sensitization function of light sensitive diode, in turn ensure that it is not affected by outdoor adverse circumstances.The encapsulation process of junction ensure that the sealing that device is overall so that it is adapting to outdoor complicated meteorological condition, the mode of inner side gluing decreases the impact on light sensitive diode susceptiveness, and can extend the life-span of fluid sealant
A circular hole matched with light sensitive diode diameter is had on back casing lateral wall, light sensitive diode leans out the surface of back casing by this hole, chip in light sensitive diode is positioned at back casing wall outer surface institute in the plane, the part that light sensitive diode leans out back casing surface is the biggest, its probability being broken words by environmental factorss such as hails is the highest, chip in light sensitive diode is primary photosensitive parts, the optical signal outside feedback that during only it is sufficiently exposed to ambient light conditions, ability is good, in this utility model, the installation site of light sensitive diode can reasonably take into account above 2 points.
Photosensitive diode chip is positioned at back casing wall outer surface institute in the plane, the position of photosensitive diode chip is the position of the extraneous light intensity of light sensitive diode impression, the position of chip is if above back casing wall outer surface place plane, light sensitive diode is easily subject to the impact from back casing wall outer surface reflection light, if the position of chip is less than back casing wall outer surface place plane, light sensitive diode is then by the interception of back casing sidewall, and the accuracy of both light intensity extraneous to light sensitive diode impression impacts.
Described light sensitive diode top is water white transparency hemispherical, and described photosensitive diode chip is positioned at the hemispherical centre of sphere.The water white transparency spherical designs of light sensitive diode, ambient can be made to come together on the chip at the hemispherical centre of sphere, the light intensity that this Design enlargement is extraneous, coordinates the Intensity threshold of sensitive chip to select, can keep the light sensitive diode at the accuracy of low light intensity interval selection light intensity critical point.
Circuit control module also includes that LED drive power, LED drive power electrically connect with light-operated circuit plate, and LED drive power fits in the inner surface of the rear wall of back casing, and the diagonal along rear wall is installed.LED drive power is the original paper that in back casing, volume is bigger, and its length determines the size of back casing, thus affects outward appearance and the materials of device, and space can be effectively saved in the design using diagonal to install, and reduces back casing size.
The diagonal that LED drive power installation is carried over is in two diagonal of back casing rear wall away from light sensitive diode.LED drive power is the heat producing components in back casing, the life-span of light sensitive diode and temperature have negative correlation, therefore in this utility model, the diagonal that LED drive power installation is carried over is in two diagonal of back casing rear wall away from light sensitive diode, after the decrease on the basis of shell dimension, make light sensitive diode away from thermal source, improve the life-span of light sensitive diode.
The rear wall outer surface of procapsid is provided with uniform fin, the spacing of fin is the 1/8-1/20 of procapsid rear wall length, preferably, the spacing of fin is the 1/13 of procapsid rear wall length, improve the heat sinking function that device is overall, the radiating effect of the effect of distance device of fin and the usage amount of material, under the design condition of the highest 50 degrees Celsius of ambient temperature, coordinate the thermal conductivity of fin, on the basis of considering the extraneous meteorological conditions such as wind-force, through the optimal solution that inter fin space is radiating effect and manufacturing cost of the 1/13 of those skilled in the art's test of many times proof procapsid rear wall length.
The beneficial effects of the utility model:
1. light controlling effects is more preferably reasonable, controls the switch time of LED light supplement lamp more accurately；
2. the installation site of light sensitive diode is reasonable, is effectively protected and is positioned at the light sensitive diode part that hull outside is more fragile；
The most rational in infrastructure, further improve the heat dissipation problem of device, the service life of extension fixture and the accuracy of switch.
