The application of the utility model may ensure that all of distant direct rays given off from the LED change the direction after being reflected by the curved reflective plane of the reflector and then are fully reflected, thereby increasing the utilization ratio and the photometric brightness of the light and improving the lighted appearance of the lamp, the automobile signal lamp is energy-saving, safe and high-efficiency.
Description
Technical field
The utility model relates to a kind of automobile signal light, belongs to automobile-used lighting technical field.
Background technology
Usually the light source of automobile room lamp all adopts traditional osram lamp or based on halogen bulb, and this light source exists defectives such as brightness is low, power consumption is big, and especially after motor vehicle was subjected to strong row vibrations, bulb also was easy to damage, and service life is short.And LED source is a kind of emerging form of light source recent years, especially must be to being extensive use of at automobile lamp.
But the light distributing system mode of LED signal lamp commonly used as shown in Figure 1 at present, the main light emission axle of light emitting diode 4 is parallel with the light fixture primary optical axis in the signal lamp light distributing system, most of light that light emitting diode 4 sends is direct projection light, small part light is through speculum 2 reflections, thereby forms spot area on photometric screen.And several even tens light emitting diodes of the common needs of the signal lamp of this structure are simultaneously as light emitting source, because the brightness value of light emitting diode is very high, the light that so many light emitting diode direct projection is come out can allow illuminated person feel very dazzling, even can cause unnecessary accident.
Summary of the invention
The purpose of this utility model provides a kind of efficient, energy-conservation, safe automobile signal light.
The utility model is that the technical scheme that achieves the above object is: a kind of automobile signal light, comprise light emitting diode, speculum, drive circuit board, housing and lampshade, it is characterized in that: described speculum is installed on the housing by securing member, the reflective surface of speculum is by last reflective plane and be positioned at the arc reflective surface that the reflective plane side is used to change radiation direction and constitute, the metal fin that is welded with light emitting diode is installed in the last reflective plane of speculum, light emitting diode is positioned at the upper back of arc reflective surface, the luminous angle θ of light emitting diode is at 65～75 °, the angle of light after mirror reflects and X-axis line is at 0～45 °, drive circuit board is installed in the rear portion of speculum by securing member, and drive circuit board is electrically connected with light emitting diode.
The utility model is arranged on upper back at the arc reflective surface with light emitting diode, whole direct projection light that light emitting diode is sent change direction and reflect away comprehensively again after the arc reflective surface reflection of speculum, so improved the utilization rate and the brightness of light, improve light fixture and lighted outward appearance, because all light can compile the hot spot that forms definite shape on the cambered surface vertical with the X-axis line, thereby satisfy laws and regulations requirement, and the light that the lampshade outside is seen is the light after the mirror reflects, appearance is an area source, can not form local bright especially point, avoid producing spot light, thereby avoid dazzling sensation to the observer.The utility model is welded on light emitting diode on the metal fin, the heat that is produced in the light emitting diode work can be delivered on the big metal fin, increased area of dissipation, thereby can fast heat be diffused in the air and go, further improved light emitting diode radiating effect, reduce power consumption, thereby prolong light emitting diode service life, reach energy-saving effect.The utility model is fixed on light emitting diode in the fire resistant resin, can reduce effectively vehicle in travelling vibrations and damage light emitting diode.
