Description
Technical field
The technology of this reality invention belongs to automotive engineering field, is specifically related to a kind of LED headlamp.
Background technology
At present, distance-light one projection headlamp has been used for partial higher car, its profile air, attractive in appearance, high-grade.
Its structure & working mechanism is as follows: this wick structure is mainly by convex lens, lens carrier, speculum, light barrier, electromagnet, lamp
The compositions such as bubble, its light barrier top is manufactured into the shape of shade line needed for dipped beam.When automobile needs dipped beam, light barrier is in and closes
Conjunction state, blocks the latter half of speculum light-emitting window, the light that bulb sends, and can only penetrate from speculum top, through convex
The refraction of lens, illuminates the lower section of vehicle front road.Principle is similar to projector, and light barrier is equivalent to cinefilm, light barrier
The shape on top can accurately be irradiated on road.The dipped beam luminous intensity distribution meeting GB4599-94 car headlamp luminous intensity distribution performance standard is wanted
Ask.
When automobile needs distance light, light barrier is opened under the effect of electromagnet, and the latter half of speculum light-emitting window is not
It is blocked again, the light that bulb sends, can penetrate from the whole oral area of speculum, the refraction of planoconvex lens, illuminate vehicle front road
Road.Meet the distance light light distribution requirements of GB4599-94 car headlamp luminous intensity distribution performance standard.At present, before distance-light one projection
The shortcomings such as it is low that illuminator exists light efficiency, and the life-span is short, and noise is big.Be analyzed as follows: (1) when being in dipped beam state, the light quilt of lower section
Blocking, luminous energy fails to be used effectively, and becomes heat energy and wastes；(2) meet distance light light distribution requirements, need to increase bulb work(
Rate, or use Xe lamp bulb；(3) there is life-span short problem in headlamp uses halogen bulb or Xe lamp bulb, and at vapour
Car driving process needs frequently more to change the bulb；(4) light barrier is opened, when closing, due to the effect of electromagnet, can be produced and make an uproar
Sound.
Content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of rationally distributed, freedom from vibration is strong, noise is little,
A kind of LED headlamp of energy-saving safety.
For achieving the above object, the present invention provides techniques below scheme:
A kind of LED headlamp, is mainly sealed by LED lamp the 1st, LED drive board the 2nd, lamp glass the 3rd, lamp housing 4 and assemblies, and its feature exists
In described LED lamp 1, mainly by convex lens (1), lens carrier (2), speculum (3), horizontal light barrier (4), LED light source
(5) sealing assemblies, it is characterised in that: described horizontal light barrier (4) is manufactured into needed for dipped beam near the end of convex lens (1)
The shape of "cut-off"line, described horizontal light barrier (4) is separated into upper and lower two parts speculum (3), is arranged above dipped beam and joins
Light reflection mirror, lower section is distance light light distribution reflecting mirror, and described LED light source (5) is made up of upper light source and lower light source.
Preferably, the area of the top dipped beam light distribution reflecting mirror of described speculum (3) and lower section distance light light distribution reflecting mirror
Area ratio scope is: 0.8-1.5.
Preferably, the upper light source of described LED light source (5) and lower light source lay respectively at horizontal light barrier (4) upper surface and
Lower surface, wherein the upper surface of horizontal light barrier (4) faces the dipped beam light distribution reflecting mirror of speculum (3), horizontal light barrier (4)
Lower surface face the distance light light distribution reflecting mirror of speculum (3).
Preferably, the upper light source of described LED light source (5) is low beam light source, and lower light source is high-beam light source.
Preferably, when described LED lamp 1 needs to send dipped beam light, the upper light source opening LED light source (5) can send
Dipped beam light, when LED lamp 1 needs to send distance light light, opens the upper light source of LED light source (5) and lower light source can send far
Light light.
Above-mentioned lamp glass 3 refers to LED headlamp glass cover.
The shadow line producing when above-mentioned "cut-off"line refers to that light source irradiates.At vehicle LED dipped headlight, light and shade is set
Boundary line, the light that dipped headlights can be sent by shadow line produces barrier effect, LED car lamp not only can be avoided excessively dazzling,
The light of vehicle LED dipped headlight can be made to move down so that light source to the irradiation below automobile more fully, drive by beneficially automobile simultaneously
The person of sailing sees front road conditions clearly, but owing to the obstruction of "cut-off"line makes part light source become heat energy, wastes a lot of light
Energy.Partial automobile LED low-beam light is not provided with "cut-off"line for various reasons at present, and is provided with the vapour of dead line
Car LED low-beam light also due to arrange the long waste that result in luminous energy of dead line.
Beneficial effects of the present invention:
(1) it is manufactured into the shape of "cut-off"line needed for dipped beam at horizontal light barrier (4) near the end of convex lens (1), not only
LED lamp 1 sending of light when projecting dipped beam is made to meet GB 25991-2010 vapour automobile-used LED dim head lights luminous intensity distribution
Standard can require, only "cut-off"line is set in the end of horizontal light barrier simultaneously, decreases the stop of "cut-off"line, can make
The luminous energy must wasted because arranging "cut-off"line drops to minimum, decreases the waste of the energy.
(2) simple in construction of LED headlamp, compact in design, rationally, therefore there is good shock resistance, and luminous
When noiselessness produce, extend the service life of LED headlamp simultaneously.
(3) ratio of the area of the area of the top dipped beam light distribution reflecting mirror of LED lamp 1 and lower section distance light light distribution reflecting mirror
Arrange rationally, distance light that LED lamp 1 sends and dipped beam can be made can to meet the need to dipped beam and distance light for the running respectively
Ask.
