Description
Technical field
The present invention relates to headlamps, relate more specifically to the headlamp using laser as light source.
Background technology
Street, road and highway lamp are to improve the fundamental that safety tries to forestall traffic accidents.Research shows that dark is made
Into a large amount of traffic accident accident, especially when be related to the accident of pedestrian.Night pedestrian accident rate is that the three times on daytime are more.Street lamp can reduce
Pedestrian accident rate about 50%.The intersection and highway intersection for having illumination occur less than the intersection of no illumination
Accident.Sufficient street lighting is also a kind of effective means for preventing property under attack with the person at night.In addition, street corner lamp
Column hangs ornament during being also red-letter day or other Special Events or commemorates the special feature of banner.Street corner electric light is street, road
Road and highway provide a kind of clean and facilitate lighting system.
Incandescent lamp including halogen lamp, is generally used for high-pressure series circuit.High-tension line generates high effect, i.e., every watt disappears
Consumption generates more light.Moreover, one switchs the lamp that whole the street can be controlled all.One branch circuit is avoided that a lamp is burnt
Whole system is allowed to extinguish after falling.Street lamp circuit may include an automatic circuit rectifier, and electric current increases after preventing lamp burn-up, to protect
Protect the service life of remaining lamp.
High intensity discharge (HID) lamp, as high-pressure sodium lamp has in terms of photopic vision illumination compared with high effect.It is however, non-equal
The spectrum of weighing apparatus leads to lurid light occur, influences indirect vision.Metal-halide lamp luminous energy provides white light more balanced spectrum, than
It is brighter safer that high-pressure sodium lamp compares the illumination under identical situation.However, the electric arc in HID lamp generates short wave ultraviolet, one is needed
The Bohemian glass protection for absorbing ultraviolet light is arranged on around electric arc tube to prevent HID lamp component sensitive to UV light and material, such as
Polycarbonate lens and reflection dura mater, aging.Moreover, HID lamp can generate serious light dazzle and light pollution.
Light emitting diode (LED) headlight application is multiple, for example, 25,30, LED segment composition matrix.One control unit
It can individually open, close or dim each LED segment.Lamp behaviour is between halogen lamp and HID headlights before LED, but power consumption is omited
Low, longer life expectancy designs more flexible.With the continuous development of LED technology, it is contemplated that the performance of LED headlights will further improve, and
It is close, reach, in some instances it may even be possible to more than HID headlights.However, LED light per unit light output generates notable heat.Different from traditional light
Source heat source coincide with light source, and the heat of LED is generated at rear portion.Different from incandescent lamp and HID xenon lamp, LED light is easily damaged by high temperature.
Operation can irreversibly reduce LED light performance at a high temperature of more than junction maximum permissible temperature for a long time, and finally shorten it
Service life.To keep LED junction low temperature in high power operation, there need to be heat management measure, such as very heavy and expensive
Radiator and/or cooling fan.In winter, excessive low temperature also results in maximum value of the LED light output more than specification.
As aspect demand that is efficient, safe and convenient, comfortable, reducing effect on environment is continuously improved, one kind is conducive to movement
The benefit of the high-effect headlamp of field, street, road, highway etc. is increasingly shown.Headlamp should provide one not only safety but also comfortably may be used
The white balance light seen, while should be a kind of construction, operate and safeguard time saving and energy saving light source.Headlamp should controllably meet each
Lighting demand of the kind environment under the conditions of.Headlamp should also provide reliable and lasting light source in various environmental applications.In addition,
Permanent service life also when one benefit.

According to the present invention, the reflecting surface 104 of reflector 102 is not limited to secondary object plane.Reflecting surface 104 may have other shapes to generate tool
There is the light beam 129 of various features.In addition, according to an of the invention specific embodiment, speculum 112 and/or reflecting surface 104 can be with
Comprising particle characteristic to there is the reflected beams 127 and/or 129 of point fuzziness.The reflecting surface 104 of reflector 102 can be inclined
Off axis to or rotational symmetry so that the extension of light beam 129 and final light beam 131 along a direction be more than with along its vertical direction
Extension.Reflecting surface 104 also can a projecting beam 129 make it and the final extension for making light beam 131 along a direction is more than and edge
The extension of its opposite direction.In addition, laser lamp 100, which can include light-blocking structure (being not shown in Fig. 4), limits light beam 131 in certain
The region specified.Beneficial to reduction light pollution in this certain application.
The color and intensity of 100 light beam 131 of laser lamp can pass through three simulated lasers of laser driver 51 (shown in Fig. 3)
Drive signal, 52,54 and 56 controls.It is stronger clearer would generally to generate one when illuminated by blue light for an object in dark
Reflection.Therefore according to a preferred embodiment of the present invention, when laser lamp 100 has meeting to vehicle at night traveling and row for illuminating
People forms the street of dangerous obstacle or zig zag, and when road or highway, the tune of laser light source module 50 is practiced midwifery in laser lamp 100
The raw combined laser beam 37 with more blue lights.On the other hand, in driving at night, a main security risk is to head on
And the dazzle that the car light for carrying out vehicle generates.Since yellow light dazzle is smaller, according to a preferred embodiment of the present invention.Work as laser lamp
100 for illumination street, light pollution can be to vehicle around road or highway, and pedestrian or when nearby resident impact swashs
The tune of laser light source module 50 is connect to generate more red lights and green light so that Huang is presented in combined laser beam 37 in light lamp 100
Color.In some special occasions, for example, for example, festival and special event or accident, special color lamp or flash lamp can be used for expression to like
Celebrating atmosphere gives a warning.In such an application, laser driver 51 in response to controlling signal, generate corresponding simulated laser
Drive signal is to generate the combined laser beam 37 with certain color, intensity and/or temporal mode.For example, combined laser beam 37
Color and/or intensity can change over time.
Actuator 58 (as shown in Figure 3) is set as adjusting laser module 10 relative to laser lamp in laser light source module 50
100 position and direction.Specifically, 58 adjustment combined laser beams 37 are performed in lamp chamber room 121 relative to 112 He of speculum
With the direction of reflector 102, so as to effectively influence laser lamp 100 light beam 131.
