Hood 140 forms the part of plane, can be positioned against the position on the top of vehicle lamp.What light source 110 was launched
Light is reflected by the lower part of reflector 120, by lens 130 focus when, 140 former state of hood is by vehicle lamp
The light of 100 upper ends transmitting, upward diverging light.
Such as 3c, vehicle lamp 100 can form L mode（L）Beam pattern.
The part that hood 140 protrudes may be mounted at the upper end of vehicle lamp 100.At this moment the one of 140 left side of hood
Region can protrude.Hood 140 is then 90 ° of angle fan shapes from right side in the form that left sides are a semicircles.Hide
The projection of light shield 140 can cut off the left field of upward diverging light.Hood 140 can cut off vehicle lamp 100 and shine
It is mapped to the light in the driver's seat direction of the vehicle to come from opposite carriageway.
Such as Fig. 3 d, vehicle lamp 100 can form P patterns（P）Beam pattern.
The part of the formation plane of hood 140 can face the bottom of vehicle lamp 100.It is anti-from the lower part of reflector 120
The light penetrated, through lens 130 focus when, hood 140 can cut off the light for being irradiated to 130 upper end of lens comprehensively.Hood
140 make vehicle lamp 100 play the role of dipped headlight (low beam).
Such as Fig. 3 e, vehicle lamp 100 can form E patterns（E）Beam pattern.
The part that hood 140 forms plane can face reflector 120.At this moment hood 140 forms the portion of curvature
Dividing can be located at towards the position of lens 130.Hood 140 is cut off to be reflected by reflector 120, there is provided to the one of 130 upper end of lens
Part light.
Fig. 4 a and Fig. 4 b are the control method precedence diagrams of vehicle lamp in the embodiment of the present invention, and Fig. 5 is vehicle lamp
Concept map.
Such as Fig. 4 a, Fig. 4 b and Fig. 5, the control method of the vehicle lamp of the embodiment includes：Above-mentioned vehicle passes through vehicle sense
Know that portion 220 perceives the stage with the presence or absence of other vehicles（S110）, according to the rank of the vehicle presence or absence of perception startup hood
Section（S120）, calculate stage of the vehicle location of perception（S130）, corresponding to the position of vehicle, move left and right the light of vehicle lamp
The stage of axis（S140）, and the stage of hood formation L-type beam pattern（S150）.
The control method of vehicle lamp according to the embodiment is to perceive whether there is other vehicles by vehicle sense part 220
Stage（S110）In by vehicle sense part 220 perceive whether there is other vehicles.
The above-mentioned stage（S110）In if opposite carriageway without the vehicle that comes of enforcement, vehicle lamp can light to
Upper irradiation.
The above-mentioned stage（S110）In if opposite carriageway is exercised to come other vehicles, vehicle sense part 220 can be to control
Transmit signal in portion 260.

Vehicular visual keep clear.Vehicle lamp forms L-type beam pattern, it can be ensured that the visual field of vehicle traveling lane state, at the same time
Ensure the visual field of the driver of the vehicle to come from opposite carriageway.
Such as Fig. 4 b, according to the vehicle perceived there are situation, start the stage of hood（S120）After the completion of, it can also wrap
Include：Calculate the stage for having perceived vehicle location（S130）；Corresponding to the position of vehicle, the rank of the optical axis of vehicle lamp is moved left and right
Section（S140）.
In the stage calculated into row position having perceived vehicle（S130）In, position calculating part 230 can calculate slave phase
The position for other vehicles that anti-lanes come.Position calculating part 230 can transmit signal to control unit 260.Position calculating part
230 can be scaled signal form other vehicle distances to come from opposite lanes transmits to control unit 260.
Corresponding to the position of vehicle, in the stage for the optical axis for moving left and right vehicle lamp（S140）In, control unit 260 corresponds to
In from 230 received signal of position calculating part, signal can be transmitted by drive division 250 to the left and right.Left and right drive division 250 is in order to avoid light
The direction for the vehicle that direct irradiation comes from opposite lanes, adjusts the optical axis of optical module 210, ensures that opposite
The driver's of track vehicle gets a clear view, and has ensured mutual safety.
Performing the control device of the control method of above-mentioned vehicle lamp includes optical module 210, vehicle sense part 220, position
Put calculating part 230, hood drive division 240, left and right drive division 250 and control unit 260.
210 irradiation light of optical module, can be to beam pattern as defined in vehicle front offer.
