Abstract
The utility model relates to a light emitting diode (LED) light guide module for a signal lamp. The LED light guide module comprises a light guide part and an LED. The light guide part is sector-shaped, a coupling surface is arranged on a small end surface of the light guide part, and the LED is arranged on the side of the light guide part provided with the coupling surface. The light guide part is provided with a slanting first reflection surface located on one lateral surface and a second reflection surface of an arc large end surface, and an arc second light emitting surface opposite to the first reflection surface and more than three second light emitting surfaces which are arranged on the back portion of the second light emitting surface at intervals and opposite to the second reflection surface are arranged on the other lateral surface of the light guide part. The first reflection surface and a first light emitting surface form a first optical system, and the second reflection surface and the second light emitting surfaces form a second optical system. The LED light guide module is compact in structure and can shorten the development period.
Description
Technical field
The utility model relates to a kind of LED optical waveguide module for signal lamp, belongs to the motor vehicle signal lamp technical field.
Background technology
Along with the development of LED technology, the application of LED is more and more extensive, has been used at present particularly in automobile lamp and illumination lighting engineering field.
At present for the luminous intensity distribution of signal lamp, each function reflecting surface needs redesign, and configures new mould and manufacture, so the manufacturing cycle of sort signal lamp is long, and cost is large.Along with the continuous variation of vehicle moulding, also require the lamp cavity space of signal lamp also more and more less and more and more meticulousr.But the light source of classical signal lamp not only needs to consider the problem that sheds of luminous intensity distribution and heat, nor can adapt to the requirement of vehicle different shaping, and therefore existing taillight is difficult to satisfy day by day outward appearance and the instructions for use of fashion.
Summary of the invention
The purpose of this utility model is to provide a kind of compact conformation, can shorten the LED optical waveguide module that is used for signal lamp of construction cycle.
the utility model is that the technical scheme that achieves the above object is: a kind of LED signal lamp module for signal lamp, it is characterized in that: comprise light guide therefor and light emitting diode, described light guide therefor is fan-shaped, the small end face of light guide therefor has coupling surface, light emitting diode is arranged on coupling surface one side of light guide therefor, light guide therefor has and is positioned at a side and tilting the first reflecting surface and the second reflecting surface of arc large end face, the another side of light guide therefor has curved second exiting surface relative to the first reflecting surface and is arranged on the second exiting surface rear portion and second exiting surface that three or more be interrupted relative with the second reflecting surface, wherein, the first reflecting surface and the first exiting surface consist of the first optical system, the second reflecting surface and the second exiting surface consist of the second optical system.
the utility model adopts a light guide therefor, side of this light guide therefor and arc large end face have respectively the first reflecting surface and the second reflecting surface, the second exiting surface that the another side of light guide therefor has the second exiting surface of arc and is interrupted more than three, due to the first reflecting surface and the first exiting surface formation the first optical system, and the second reflecting surface and the second exiting surface consist of the second optical system, therefore the light of light emitting diode enters by the coupling surface of light guide therefor, penetrate from the first exiting surface after making a part of light through the first reflecting surface reflection on light guide therefor, another part light penetrates from the second exiting surface after the second reflecting surface reflection on light guide therefor, to reach the required light distribution requirements of signal lamp, the utility model is owing to not needing that each signal lamp is offered mould and manufacturing again, can save material, shorten the construction cycle.Optical waveguide module of the present utility model can be used in combination being combined on signal lamp, and is easy to use, and compact conformation is saved the light fixture space, can satisfy day by day outward appearance and the instructions for use of fashion.The utility model adopts light emitting diode to use as light source, saves energy resource consumption, reduces light fixture and produces heat, can reduce the lamp cavity temperature to avoid the problem of fog and heat generation.
