Description

A kind of LED motorcycle headlamp
Technical field
The present invention relates to a kind of motorcycle assembly, particularly relate to a kind of LED motorcycle headlamp.
Background technology
Motorcycle headlamp is one of important security part of motorcycle.At present, motorcycle headlamp generally by lamp socket, dipped headlights, high beam, daytime portable lighter and lampshade form, dipped headlights, high beam and daytime portable lighter mostly adopt incandescent lamp as light source, this type of light source volume is large, power is high, caloric value is large, service life is relatively short.Meanwhile, dipped headlights, high beam and daytime portable lighter or be each position being separately mounted at motorcycle, make the headlamp of motorcycle compact not, assembling is inconvenient, dipped headlights, high beam and daytime portable lighter be arranged in same reflector, share a light distributing system, light distribution effect is bad.
Summary of the invention
Above-mentioned deficiency is there is in order to overcome in prior art, the invention provides a kind of simple and compact for structure, energy-conserving and environment-protective, longevity, volume is little, caloric value is little LED motorcycle headlamp, dipped headlights assembly in it, high beam assembly and daytime portable lighter assembly there is relatively independent light distributing system separately, light distribution effect is good.
The technical scheme that the present invention solves its technical problem is: a kind of LED motorcycle headlamp, comprise the lamp housing with inner chamber, be fixedly connected on the lampshade on this lamp housing, the tilted portable lighter assembly in daytime being provided with a strip of the inner chamber of described lamp housing, this, portable lighter assembly comprised strip substrate in daytime, be disposed side by side on the portable lighter speculum in multiple daytime on this strip substrate, and LED portable lighter in the daytime pearl be located in portable lighter speculum in each daytime, the dipped headlights assembly of the below on the top being positioned at portable lighter assembly in described daytime is also provided with in the inner chamber of described lamp housing, and be positioned at the high beam assembly of below of bottom of portable lighter assembly in described daytime, described dipped headlights assembly comprises dipped headlights speculum, be located at the LED low-beam light pearl in this dipped headlights speculum, be located at the dipped headlight lens in the front of this dipped headlights speculum, and the shadow shield be located between this dipped headlight lens and dipped headlights speculum, described high beam assembly comprises high beam speculum, and the LED high beam pearl be located in this high beam speculum.
Further, multiple described daytime, one made by portable lighter speculum, and each described daytime, portable lighter speculum was made up of latticed higher order reflection face, and structure is simple, and reflecting effect is better.
Further, the reflecting surface that described dipped headlights speculum is made up of multiple paraboloid of revolution forms, and have a described LED low-beam light pearl in described dipped headlights speculum at least, reflecting effect is good.
Further, described high beam speculum is at least made up of a reflector, this reflector is made up of the distance light plane of reflection of distance light reflecting curved surface with the below being positioned at this distance light reflecting curved surface, and the focus of described distance light reflecting curved surface is on the described distance light plane of reflection, the focus place described distance light plane of reflection being positioned at described distance light reflecting curved surface is provided with LED high beam pearl mounting groove, is provided with described LED high beam pearl in this LED high beam pearl mounting groove.LED high beam pearl is arranged on the distance light plane of reflection of high beam speculum, the light that LED high beam pearl sends is reflected away by distance light reflecting curved surface, to the existence of LED high beam pearl be can't see from front, the personnel of sending a car can be avoided to produce dazzling because of direct view led high beam pearl.
Further, described reflector has 3, and is arranged side by side and makes one, and in each described reflector, correspondence is provided with a described LED high beam pearl, and structure is simple, and illuminating effect is better.
Further, described dipped headlights assembly and high beam assembly are fixed on a heat sink by aluminium base, effectively can reduce the generation of heat in lamp housing.
Further, described aluminium base and be provided with heat-conducting cream between described dipped headlights assembly and high beam assembly, guarantees heat transfer effect, reduces the generation of heat.
Further, described radiator is made up of aluminium, is provided with heat-dissipating space between described radiator and described lamp housing, and described radiator is provided with many radiating ribs, guarantees efficiently radiates heat.
Further, described LED portable lighter in daytime pearl, LED low-beam light pearl are all connected with a constant current source driving circuit with LED high beam pearl, constant current source driving circuit designs for the characteristic of high-capacity LED element, for each LED element provides stable operating current, it effectively can avoid the current drift because temperature rise causes, and avoids LED element to occur large light decay.
In use, when needs use high beam, open LED high beam pearl, the light that LED high beam pearl sends reflects to form horizontal exit light by high beam speculum in the present invention, and light is concentrated and brightness is comparatively large, can illuminate distant place pedestrian, vehicle, road guideboard etc.When needs use dipped headlights, open LED low-beam light pearl, the light that LED low-beam light pearl sends reflexes on dipped headlight lens by dipped headlights speculum, and penetrate from dipped headlight lens, can under not direct projection the other side sends a car prerequisite, illuminate advance road surface and pedestrian, shadow shield and dipped headlight lens form secondary optical system, thus form dipped headlights "cut-off"line.When needs use portable lighter in daytime, open LED portable lighter in daytime pearl, the light portion direct projection that LED portable lighter in daytime pearl sends is gone out, another part is reflected away by LED portable lighter in daytime speculum, other users of road are allowed to find oneself as soon as possible, be mainly used in, in the poor situation of driving line-of-sight circumstances, increasing visibility when driving a vehicle in the daytime, reducing the occurrence probability of traffic accident.The LED motorcycle headlamp of this structure adopts LED as light source, because LED power is lower, therefore not high to the power demand of the electricity generation system of motorcycle engine, this for because of structure restriction, magneto generating power output engine less than normal more effective.
Beneficial effect of the present invention is: 1, adopt LED as light source, thus motorcycle headlamp is had, and energy-saving and environmental protection, longevity, caloric value are little, brightness advantages of higher.2, LED volume little, be easy to fixing, ensure that the stability of light source and the vibration test requirement of whole motorcycle headlamp.3, by dipped headlights assembly, high beam assembly and daytime portable lighter assembly be arranged in same lamp housing, simple and compact for structure, and dipped headlights assembly, high beam assembly and daytime portable lighter assembly there is relatively independent light distributing system separately, light distribution effect is good.4, be provided with cooling system in lamp housing, good heat dissipation effect, increase the service life.
