Description
Technical field
The utility model is related to technical field of automobile illumination, specially a kind of automobile headlamp with an automatic light meter.
Background technology
Automotive lighting provides illumination in the case of night or low visibility, to driver, passenger and traffic administration personnel,
Prompt and warning are risen to other vehicle and pedestrians.The road and object of headlamp being mainly used for before mobilite, it is ensured that driving
Safety.It can also be using distance light, dipped beam checker as night overtaking signal.Headlamp is mounted on the both sides on automobile head,
Each car fills 2 or 4.Bulb power is 45 ~ 60W of high beam, 25 ~ 55W of dipped headlight.
Headlamp will provide good illumination, and should reduce dazzle to the greatest extent.For headlamp, above-mentioned two aspect is wanted in order to balance
It asks, using two kinds of operating modes of distance light and dipped beam.Distance light is in front without the remote photograph for carrying out vehicle or while not trailing other automobiles uses
Mingguang City's beam, by reflector focal point, main filament that power is larger generate, beam direction level of approximation.The usually single lamp of regulation
Maximum emission intensity should be not less than 20,000 candelas.In order to ensure traffic safety, the illumination distances of distance light（It was found that and identification barrier
Hinder the distance of object）It should be greater than realizing the braking distance to stop in time.In view of required distance light luminous intensity about with speed 4
Power is directly proportional, and most countries carry out speed limitation.In addition, in order to when instant and near light operating mode converts, it is unlikely to because bright
Dark variation is greatly different and driver's short time is made to lose identification capacity, thus provides：The distance light maximum emission intensity of all headlamps
Summation must not exceed 22.5 ten thousand candelas.Dipped beam is the short distance illuminating bundle used when intersecting vehicle or trailing other automobiles,
It is generated by lower-powered auxiliary filament, is projected downwards because deviateing reflector focal point and optical axis, light beam.In order to limit levels direction with
On light beam, metal light-shield cover is housed usually below auxiliary filament, is just formed with light and shade abrupt change in this way on vertical screen
Light shape is carried out vehicle driver's eyes and is located in dipped beam light shape dark space when intersecting vehicle, to inhibit dazzle to the maximum extent.
But since car lighting lamp all keeps the consistency of its illumination in general, then in external ambient brightness
Driver's naked eyes can not adapt in time when change, so that driver's eye of vehicle generates the feelings for being not suitable with surrounding enviroment
Condition, to produce security risk.
Utility model content
The purpose of this utility model is to provide it is a kind of can be voluntarily according to the illumination variation of surrounding enviroment to car lighting lamp
Brightness be adjusted, driver's ophthalmic uncomfortable is led to due to periphery brightness change to reduce, influences the feelings of normal driving
Condition, while reduction vehicle own power consumption can also be played, extend the service life of power equipment in vehicle, it is above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of automobile headlamp with an automatic light meter, packet
Include pedestal, main light source, secondary light source, photosensitive sensor, control circuit and lampshade, the pedestal for no upper cover the bucket-shaped knot in four directions
Structure, the base bottom are fixedly installed control circuit, and the pedestal intracavity bottom position right over control circuit is equipped with main light source,

Structure lampshade is respectively provided on the outside of each top margin of pedestal there are one photosensitive sensor, the control circuit by conducting wire respectively with it is described
Secondary light source and photosensitive sensor conducting.
Preferably, pedestal top outer edge is the slope surface to pedestal back sweep, the slope surface and pedestal outside
Surface is in 5 ° ~ 20 ° of angle, and the sensing end surfaces of the photosensitive sensor are parallel with the slope surface.
Preferably, connection light barrier is provided on the inside of lampshade, the connection light barrier is embedded in the base interior, the company
The plate surface that is in the light is connect with the base internal wall to be close to.
Preferably, if secondary light source is arterial highway LED light strip arranged in parallel, the LED light strip respectively with the control
Circuit is electrically connected.
Compared with prior art, the utility model has the beneficial effects that：
（1）The utility model is made by the cooperation of pedestal, main light source, secondary light source, photosensitive sensor, control circuit and lampshade
With, voluntarily the brightness of car lighting lamp can be adjusted according to the illumination variation of surrounding enviroment, to reduce due to periphery it is bright
The case where degree variation leads to driver's ophthalmic uncomfortable, influences normal driving, while reduction vehicle own power can also be played
Consumption extends the service life of power equipment in vehicle.
（2）Pedestal top outer edge is the slope surface to pedestal back sweep, can reduce main light source, secondary light source to photosensitive biography
The influence of the induction end of sensor, so that photosensitive sensor further increases the sensitivity of the luminance detection of external environment.
（3）It is provided with connection light barrier on the inside of lampshade, main light source, secondary light source is further reduced to external scattering, improves
The illumination distances of main light source, secondary light source, additionally it is possible to ensure being isolated between main light source, secondary light source and photosensitive sensor.
（4）If secondary light source is arterial highway LED light strip arranged in parallel, what control circuit was opened by controlling LED light strip
