Description
Technical field
The present invention relates to a kind of lighting assembly for vehicles being made of the optical unit of flat shape.
Background technique
Nowadays, new Vehicular illumination system is not focused only on the optics that driver comfort and travel safety can be improved
Output, and begin to focus on the appearance of the lighting devices such as automotive headlight or signal lamp.The rise of point light source and area source,
Especially LED and OLED light source open new chapter for the style selection of Automobile Design teacher.
The application of planar light source, especially OLED(Organic Light Emitting Diode) not only expand the possibility that light-emitting function designs
Property, and be also equipped with certain technical benefits, comprising: compact installation dimension, low in calories, low energy consumption etc..Unfortunately,
OLED technology remains deficiency, such as: the service life is short, moisture penetration, low in energy consumption, flat luminous limitation, it is most important that,
Cost is excessively high, therefore, also fails to be unfolded to be widely applied in the batch production of automotive lighting.OLED technology has another disadvantage that
Vehicular lamp must be adjusted to detect the erroneous condition of light source.Under kindred circumstances, traditional LED is relatively easy to detect, because
In most cases, the variation that electricity caused by short circuit or diode disconnection occurs is easy to be arrived by detection of electrons.It compares,
The case where area source, is increasingly complex, because the organic layer for constituting OLED is shone after connecting voltage/current.

US20160349570, US20150331169, US20140268873, US20130033895, US20110249939,
In US20110170315, US20100309677, US20080186726, GB2537088, KR2008111786, there are many
Solution is to replace the organic substance of OLED with the optical unit of the flat shape with outgoing area to realize the output of light.
The shortcomings that above-mentioned design scheme, is that these optical units are not typically used as the exterior lighting equipment of motor vehicle, because it must
It must follow and meet various technical specifications and laws and regulations requirement.In addition, these devices either manufacture or assemble, be required to it is low at
This.Such as: the coverslip of the chemosetting used in display screen manufacturing process is not suitable for automotive headlight, because its
Manufacturing cost is too high.
In order to realize the peak efficiency of lighting device, it is necessary to ensure that effective combination of light and light guide core components.Arrangement folding
When penetrating the relevant optical element of face, reflecting surface, optical environment junction, it is necessary to prevent light losing to the full extent as far as possible,
The ray trajectory of characteristic needed for capable of exporting also is wanted to realize the light intensity of needs that is, by the constant luminance on all exit facets simultaneously
With uniform appearance.
Automotive lighting has certain particularity, it is directed not only to the appearance and total brightness of illumination functions.Its each illumination
Function has to comply with locally significant regulation (such as ECE, SAE, CCC etc.).Minimum luminous intensity of each function to special angle
Value and maximum emission intensity value have different requirements.This means that not only to issue a certain number of light from light-emitting component, also need
There is the light of certain light intensity in all angles transmitting of rules and regulations.The luminous intensity is based on independent rules and regulations all angles
Minimum value and maximum value.The design of illumination functions will meet the requirement of regulation as much as possible.Also therefore, as defined in all angles
There are certain overlappings at the interval of minimum value and maximum value.In this case, a lamp or headlight may not need correcting and
It is applied to more markets simultaneously.But in some cases, individually designed illumination functions are unable to satisfy the requirement of all regulations.
In such a situation, it is necessary to so that illumination functions is adapted to the requirement in each market, so that uniqueness could be provided for particular market
Product.
The luminous intensity of all angles requires to be all based on requirement of traffic safety.This is because the main task of signal lamp is true
The signal for protecting motor vehicle sending can be from important angle.The light for the light that all semiotic functions (except side signal lamp) issue
It by force must be highest in axial direction.With the increase of the axis deflection angle, the requirement to the luminous intensity values of all angles is therewith
It reduces.This decline is progressive and not approximate Lambertian distribution (cosine emitter).Therefore, it does not need to strive for this yet
Kind (Lambert) distribution, the distribution of g light intensity when working close to OLED luminaire or some displays.Display and TV screen
Curtain is to ensure stable brightness from visual angle as wide as possible, this is the maximum area required with lighting assembly for vehicles light intensity angle
Not, according to the present invention, lighting assembly for vehicles is also limited.
As described above, the light under big visual angle fades and is regarded as the defect of display and video screen.On the other hand,
The signal lamp of motor vehicles is limited by standardizing, it is necessary to realize corresponding luminous intensity in all angles to ensure to emit signal
Vehicle secure visual.In most cases, the light cone of generation must in the horizontal direction +/- 10 °, perpendicular to the vehicle longitudinal axis
There is highest luminous intensity within the scope of +/- 5 ° of direction.Then luminous intensity is at axial direction is at +/- 20 ° and +/- 10 ° of angles
Diminuendo.Main beam needs these angles, and the required luminous intensity of the luminous strength ratio other angles of main beam is several times high.At other
Angle, visuality are only relative parameter, and signal is visible from large-scale angle.For example, for braking function, it need to be in level
It in +/- 45 ° and is vertically in keep visible in +/- 15 ° of angular range.However, for taillight and turn signal function, vehicle can
See that angle has extended to 80 °.About production tolerance issues, optical design is extremely important, it must be made always to meet under special angle
Required luminous intensity values.Therefore, the design of minimum value and maximum value usually all stays certain nargin for angle and value.This means that
If needing a minimum luminous intensity in some angle, the common design method of the function can make the minimum value at least
Greater than 1.5 ° of given angle.
Foregoing description indicates that effectively meet rules and regulations, it is necessary to carry out optical design for all angles.
It is different from display and video screen, in the automotive industry, it is necessary to deeply consider required output face shape.Cause
For that in most cases, can not be received with the angle of designer using single square or rectangular surfaces.Nowadays, vehicle configuration
Many restrictions are also caused in terms of meeting technology and legal requirement while as important parameter.Therefore, moulding must and skill
Art feature, which combines, can be only achieved ideal effect.For this purpose, the design of light guide core must optimize the distribution and size of dispersing element.
The purpose of the present invention is introducing a kind of new solution of motor vehicle lighting equipment, by with beam projecting area
The optical unit of flat shape is constituted.Optical unit is bright by point light source (LED) confession, and optical element is housed, and generates signal lamp function
Can, face optical unit can provide the design advantage to compare favourably with OLED technology, while ensure meet all technical specifications and
Under legal requirement, the lighting apparatus manufacturing cost of the auto industry of rationalization is obtained.
