Abstract
The utility model relates to a kind of photophore for laser Rear Fog Lamp, comprise housing, the infrared laser array that more than three infrared laser chips are formed and longitudinal refractor and lateral refraction lens, the infrared laser chip place be arranged in housing is also provided with thermistor, longitudinal refractor to be arranged in housing and to be positioned at the front portion of infrared laser chip, described longitudinal refractor has outer convex globoidal and the upper and lower deviation of red laser light beam for infrared laser array being sent forms longitudinal angle at the red laser light beam of 10 ° ± 1 °, the lateral refraction lens being arranged on housing front portion are positioned at the front portion of longitudinal refractor, inside described longitudinal refractor for cancave cambered surface and for by longitudinal refractor through red laser light beam left and right deviation and formed lateral angle 20 ° ± 1 ° red laser light beam injection.The red laser that the light penetration power that photophore of the present utility model sends is strong, has better warning function, can ensure traffic safety.
Description
Technical field
The utility model relates to a kind of photophore for laser Rear Fog Lamp, belongs to automotive lamp technical field.
Background technology
Dense fog is one of arch-criminal caused a serious accident, if can point out rear car in time at travelling in fog day, effectively can reduce the generation of rear-end collision.Tradition Rear Fog Lamp generally adopts halogen light source or LED light source, is no matter that the ability of halogen light source or its penetration power misty rain of LED light source is all much weak than the red laser of narrow spectrum, high directivity.Moreover the equal spot light of light beam that existing traditional fog lamp and LED fog lamp appear, because visible surface is little, so weaken the fog lamp function eye-catching in misty rain sky.
Summary of the invention
The purpose of this utility model is to provide a kind of photophore for laser Rear Fog Lamp, the red laser that the light penetration power sent is strong, has better warning function, to ensure traffic safety.
The utility model is the technical scheme achieved the above object: a kind of photophore for laser Rear Fog Lamp, it is characterized in that: comprise housing, the infrared laser array that more than three infrared laser chips are formed and longitudinal refractor and lateral refraction lens, the infrared laser chip place be arranged in housing is also provided with thermistor, longitudinal refractor to be arranged in housing and to be positioned at the front portion of infrared laser chip, described longitudinal refractor has outer convex globoidal and the upper and lower deviation of red laser light beam for infrared laser array being sent forms longitudinal angle at the red laser light beam of 10 ° ± 1 °, the lateral refraction lens being arranged on housing front portion are positioned at the front portion of longitudinal refractor, inside described longitudinal refractor for cancave cambered surface and for by longitudinal refractor through red laser light beam left and right deviation and formed lateral angle 20 ° ± 1 ° red laser light beam injection.
The utility model adopts infrared laser array as light source, red laser light beam is through the red laser light beam of longitudinal refractor formation longitudinal angle at 10 ° ± 1 °, again through lateral refraction lens, make red laser light beam left and right deviation and formed lateral angle 20 ° ± 1 ° red laser light beam injection and crossing with ground, on the basis that satisfy regulatory requires, the visible surface of warning is large, only good directionality.The utility model adopt red laser can in diffraction air oarse-grained ability strong, therefore farther distance can be penetrated under blind environment, there is good penetration performance, have better warning function, ensure traffic safety.The utility model laser adopts infrared laser chip, and red laser is monochromatic source, and its breadth of spectrum line is narrow, penetration capacity Relatively centralized, and the ratio between its laser brightness and sunlight is 1,000,000 grades, and therefore power density is large, fast response time.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model photophore.
Wherein: 1-housing, 2-thermistor, 3-infrared laser chip, 4-longitudinal refractor, 5-lateral refraction lens.
Detailed description of the invention
As shown in Figure 1, the utility model is used for the photophore of laser Rear Fog Lamp, comprise housing 1, the infrared laser array that more than three infrared laser chips 3 are formed and longitudinal refractor 4 and lateral refraction lens 5, infrared laser array is arranged in housing 1 by mount pad, drive circuit is connected with infrared laser chip 3 by wire, the utility model is for play a protective role to infrared laser chip 3, at infrared laser chip 3, place is also provided with thermistor 2, when the temperature increases because thermistor resistance increases, drive circuit is made not provide power supply to infrared laser chip 3, and play a protective role.
As shown in Figure 1, the utility model longitudinal refractor 4 be arranged on housing 1 is positioned at the front portion of infrared laser chip 3, longitudinal refractor 4 has outer convex globoidal and forms longitudinal angle at the red laser light beam of 10 ° ± 1 ° for the upper and lower deviation of red laser light beam infrared laser array sent, and lateral refraction lens 5 are arranged in housing 1 and be positioned at the front portion of longitudinal refractor 4, inside this longitudinal refractor 4 for cancave cambered surface be used for by longitudinal refractor 4 through red laser light beam left and right deviation and formed lateral angle 20 ° ± 1 ° red laser light beam injection, red laser light beam has a down dip and crossing with ground, the light of the triangle to an inclination warning sign can be become in misty rain sky, stronger warning function is had to front vehicle.
As shown in Figure 1, housing 1 of the present utility model comprises upper shell and lower house, longitudinal refractor 4 and lateral refraction lens 5 to be arranged on lower house and to be fixed by upper shell pressing, housing 1 is installed on a heat sink, by radiator, the heat produced in photophore work is derived, photophore reliably working.
