Description
Technical field
The present invention relates to the car lighting lamp technical field, particularly a kind of vehicle-mounted light filling system and control method thereof.
Background technology
At present, application number is that the patent of CN200720017131 discloses remote infrared laser grenade instrumentation, and this device adopts the red infrared illumination light of the infrared laser of specific wavelength as light source; Main ray structure comprises laser generator and infrared light double lens; This infrared light supply volume of Laser emission infrared light that utilizes is relatively big, and the infrared light emissive power is smaller, and light intensity is concentrated and is difficult for scattering; Eyes to the people have injury, are unsuitable on automobile and install and use.
Application number is the disclosed intelligent light filling of the patent of a CN200820062766 system; The used luminophor of this system is the LED lamp, but this common LED lamp is under the situation of night or bad weather, because LED light flux is limited; Cooperate video camera, be difficult to the clear vehicle license of accurately capturing.
The infrared light supply that is used for infrared light filling also has infrared Halogen lamp LED, only uses single Halogen lamp LED, makes special lampshade, adds lens, and special optical filter is equipped with in the lens the inside, and the visible light of filtering more than 50% can the infrared light of transmission more than 90%.Two lens are set before bulb, and emergence angle is 5 ° and 8 °, and 8 ° of lens outgoing are adopted in irradiation at short distance, adopt 5 ° of lens outgoing at a distance.This lamp gets shortcoming: cost is very high, need add special lens, and heat resistance is had relatively high expectations.
In order not influence reverse track driver's sight line, the range of exposures of common headlight dipped headlights has only 30 meters far away, the place that all light do not shine directly into, and the driver is difficult to see clearly, perhaps cannot see at all.Though high beam can increase irradiation distance, can not often open, otherwise can cause dazzling to the vehicle that head-on comes but since the problem of exist dazzling therefore can only under situation seldom, use.
Summary of the invention
Technical matters to be solved by this invention is, to the deficiency of prior art, provides a kind of driver's nighttime driving can see a distant place clearly, can not cause vehicle-mounted light filling system and control method thereof dazzling, that dazzle simultaneously to the vehicle driver who head-on comes.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of vehicle-mounted light filling system; Comprise two infrared light filling lamps, driving power, aluminium base, heating radiator, infrared night vision camera; Described infrared light filling lamp is arranged on the automobile fog light side, described infrared light filling lamp comprise a plurality of series connection infrared LED, cover in the outside lens of a plurality of infrared LEDs, described a plurality of infrared LEDs are connected aluminium base one side; Described heating radiator is connected the opposite side of aluminium base, and described infrared night vision camera is connected with vehicle-carrying DVD.
Described heating radiator is that layering is around heating radiator.
Silica gel through insulating heat-conductive between described heating radiator and the aluminium base is fitted and connected.
The infrared LED of described a plurality of series connection drives through constant-current driving power supply.
It is the chip for driving of CS700C that described constant-current driving power supply adopts model.
Described a plurality of infrared LED is six.
Described infrared night vision camera is transferred to the signal of gathering on the vehicle-carrying DVD and shows.
Described infrared night vision camera is provided with optical filter, and described infrared night vision camera is installed in the draw-in groove between inside-automobile rear mirror and the windshield.
The control method of a kind of vehicle-mounted light filling system, it is characterized in that: this method may further comprise the steps:
A) infrared light filling lamp emission infrared light is radiated on the barrier on road surface;
B) barrier emission infrared light is given the infrared night vision camera, and the infrared night vision camera is presented at picture signal on the vehicle-carrying DVD.
The present invention adopts said structure and method, has the following advantages: 1, in order not influence reverse track driver's sight line, this infrared light filling lamp can shine the road conditions in 150 meters, and is shown on the vehicle-carrying DVD, and the driver can see clearly at a distance.Because infrared LED lamp emission is the infrared light of 850nm ± 20nm, human eye can't see, and can replace high beam during operate as normal night, can not cause dazzling to pedestrian and the driver who goes in the same direction again simultaneously; 2, because components and parts are all responsive to heat usually, heat or too high heat are all brought the problem in stability and serviceable life for a long time.LED is a photoelectric device; Have only 10%～20% electric energy to convert luminous energy (infrared light efficient is lower) in its course of work; Remaining electric energy nearly all converts heat energy to, and in great power LED, great power LED is because the electric current low-power LED more in the past that passes through is much bigger.LED can emit great amount of heat in the course of the work, and the tube core junction temperature is risen rapidly, and LED power is high more; Heating effect is big more. shows according to experiment test: 5 degrees centigrade of the every risings of LED self temperature; Luminous flux just descends 3%, and the light fixture of infrared LED lamp is noted the heat radiation work of led light source itself among the present invention, under possible situation, strengthens the area of dissipation of led light source self as far as possible; Reduce the working temperature of LED self as far as possible; And preferably can power unit and the Lights section be separated, thereby effectively increase area of dissipation, thereby reduce the working temperature that the LED series connection waits group and power supply; 3, layering adopts layering around heat radiating fin structure around heating radiator; Aluminium base is placed in the heat radiator top, and the centre has heat conductive insulating silica gel to link together, and the heat that makes led chip send in time exports to layering to heat around heat radiator through pin and bottom aluminium base; Can effectively control the led chip temperature at 60 ℃-80 ℃; Be easy to suppress the changes of properties of infrared LED, improve electro-optical efficiency, prevent rapid aging the burning of led chip.
