Abstract

The present invention relates to methods and LED back lights that angular brightness is recognized in side view outside a kind of increase LED back lights, this method is that a LED is arranged in LED back lights, from the visible mirrored side walls edge in outside rearward position, and the outer side view that the LED direct light shines directly into laws and regulations requirement is made to recognize angular zone.The LED back lights include lamp body, LED, wiring board, speculum and lens, lens is mounted on lamp body, and surround lamp chamber with lamp body, wiring board and speculum are located in lamp chamber, and it is each attached on lamp body, speculum is in bowl-shape, its side wall reflecting surface is towards lens, LED is located at the bottom centre of speculum, and its light-emitting surface is towards lens, other one LED of setting in the sidewall edge rearward position of speculum, the light-emitting surface of the LED is towards lens, and optical axis direction is located at the outer side view of laws and regulations requirement and recognizes in angular zone.The present invention provides the modes that angular brightness is recognized in side view outside a kind of new increase LED back lights.

Description

Increase method and LED back lights that angular brightness is recognized in the outer side view of LED back lights
Technical field
Recognize the method for angular brightness the present invention relates to side view outside a kind of increase LED back lights and outer side view is realized using this method Recognize the increased LED back lights of angle, belongs to car light technical field.
Background technology
When carrying out lamps and lanterns optical design, 80 degree of requirements for meeting regulation depending on recognizing the brightness at angle on the outside of lamps and lanterns are considered.Mesh There are two types of preceding common modes：
1, by the reflected light of the highlighted side wall of aluminizing of speculum
Light source center direct light after the highlighted side wall reflection of aluminizing of speculum, arrive at laws and regulations requirement depending on recognizing angular zone, Meet regulation to the brightness requirement depending on recognizing angle.The limitation of which is, as viewed from lamps and lanterns outside, needs visible certain area Mirrored side walls.When mirrored side walls since light fitting shape blocks, and when can not expose enough areas, angular zone is recognized in outer side view Brightness will be insufficient for laws and regulations requirement.
2, by lamp distribution mirror inner surface depending on recognizing corner piece line
Light, depending on recognizing the refraction of corner piece line, arrives at outside wide-angle, plays bright outer side view and recognize corner piece by lens inner surface Line.The limitation of which is, lamp distribution mirror inner surface need certain area depending on recognizing corner piece line, have for moulding larger Impact.And since to recognize angle angle larger for outer side view, when lamp distribution mirror moulding curvature is larger, outward according to light be easy hair Raw total reflection, the effect depending on recognizing the refraction of corner piece line reduce, it is difficult to meet requirement of the regulation depending on recognizing angle.
Invention content
The present invention is intended to provide a kind of method and LED back lights for increasing the outer side view of LED back lights and recognizing angular brightness, can increase Angular brightness is recognized in the outer side view of LED back lights, while can avoid the above problem again.
The main technical schemes of the present invention have：
A method of increasing the outer side view of LED back lights and recognize angular brightness, in LED back lights, from the visible speculum side in outside A LED is arranged in wall edge rearward position, and the outer side view that the LED direct light shines directly into laws and regulations requirement is made to recognize angular region Domain.
A kind of LED back lights, including lamp body, LED, wiring board, speculum and the lens that LED is set, the lens peace Lamp chamber is surrounded on the lamp body, and with the lamp body, the wiring board and speculum are located in lamp chamber, and are each attached to institute It states on lamp body, the speculum is in bowl-shape, and side wall reflecting surface is located at the speculum towards the lens, the LED Bottom centre, and its light-emitting surface towards the lens, in addition the sidewall edge rearward position of the speculum is arranged one LED, the light-emitting surface of the LED is towards the lens, and optical axis direction is located at the outer side view of laws and regulations requirement and recognizes in angular zone, should LED is also disposed on the wiring board.
The LED back lights can also include circuit board mount, and the wiring board is fixed on institute by the circuit board mount It states on lamp body.
The beneficial effects of the invention are as follows：
The present invention can increase the brightness that angular zone is recognized in the outer side view of LED back lights, compared with existing way 1, not by speculum The influence of side wall dew size, even if light distribution mirror curvature is larger, will not be cut down depending on recognizing angular zone compared with existing way 2 The increased effect of brightness.
Description of the drawings
Fig. 1 is the structural schematic diagram of the LED back lights of the present invention.
Specific implementation mode
The invention discloses side views outside a kind of increase LED back lights to recognize the method for angular brightness, is in LED back lights, from outside In addition a LED is arranged in visible mirrored side walls edge rearward position, so that the LED direct light is shone directly into regulation and want Angular zone is recognized in the outer side view asked, to increase the brightness depending on recognizing angular zone.
This method is used, as shown in Figure 1, LED back lights disclosed in this invention include lamp body 6, LED, the circuit that LED is arranged Plate 1, speculum 3 and lens 5, the lens is mounted on the lamp body, and surrounds lamp chamber, the circuit with the lamp body Plate and speculum are located in lamp chamber, and are each attached on the lamp body, and the speculum is in bowl-shape, and side wall reflecting surface is towards institute State lens, the LED is located at the bottom centre of the speculum, and its light-emitting surface is towards the lens, the speculum Other one LED 4 of setting in sidewall edge rearward position, the light-emitting surface of the LED is towards the lens, and optical axis direction Outer side view positioned at laws and regulations requirement is recognized in angular zone, which is also disposed on the wiring board.
The present invention is directed back light, therefore the opposite so-called rear of the back light is also the vehicle body that the back light is mounted on Front.
The LED back lights can also include circuit board mount 2, and the wiring board is fixed on institute by the circuit board mount It states on lamp body.
, can be by LED4 direct lights when the sidewall area from the visible speculum in outside 3 is limited, it will be depending on recognizing angular zone Beat it is bright, to meet laws and regulations requirement, therefore overcome the defect of existing way 1.Simultaneously as mode of the present invention does not have to Dependent on lens inner surface depending on recognizing the refraction of corner piece line, therefore lens moulding is no longer limited, even if light distribution mirror curvature It is larger, it will not cut down depending on recognizing the increased effect of angular zone brightness, there is no need to worry to cannot be satisfied regulation depending on recognizing angular zone brightness It is required that.
