Abstract

The utility model relates to a downward irradiation lamp for automobiles meeting during the night. The utility model is made according to the theory of optical direction irradiation. A reflective face (1) is formed by that a circular arc which is of 180 DEG and a curve which is connected with 1/2 parabola rotate 120 DEG to form a geometric curvilinear plane; the center of circle of the circular arc is positioned on the same point of the focal point of the parabola; the light source of the downward irradiation lamp is arranged on the intersecting point of the center of circle and the focal point; the light rays irradiated from the downward irradiation lamp can only illuminate road surface lower than horizontal line; the eyes of drivers and pedestrians which are in the higher positions than the downward irradiation lamp can not be stimulated; the utility model thoroughly solves the problem that traffic accidents are easy to happen because the eyes of drivers who have automobiles meeting and pedestrians are stimulated; when automobiles meeting, drivers need not switch off the lamp, safety driving can also be ensured; the utility model is a lamp which is superior than other lamps for automobiles meeting.

Description

Downward irradiation lamp for automobiles meeting

The utility model is the vehicle low shot-light that meets at night.

Used car lighting lamp, light direct projection the place ahead, and stray light is arranged, this can stimulate the other side driver and pedestrian when meeting at night eyes cause the accident easily.So, the traffic ordinance regulation, both sides must alternately turn off the light during meeting.Though certain effect is arranged like this, but still can not solve root problem, driver's this thing of all having a headache very much.

The utility model is to address the above problem, and makes a kind of irradiation road surface, not according to the lamp that meets at night of human eye.This lamp is installed on the vehicle, and the driver needn't turn off the light during meeting, does not also stimulate opposite driver and pedestrian's eyes, but the road surface is very bright according to getting.Realized turning off the light also can safe meeting purpose.

The utility model is the (see figure 1) of making according to optical orientation irradiation principle.Adopt the center of circle and focus to be in the curve (1) that one section 180 degree circular arc on the same point (2) links to each other with one section 1/2 parabola, and with this curve with center of circle focus (2) serve as the axle make an arc 120 the degree, form a geometrical curve face, plate reflectorized material on the whole, make reflective surface (1).Locate to install light source in center of circle focus (2), make the low shot-light of meeting, light only is radiated on the road surface below horizontal, do not have light more than the level.Like this, because the other side driver and pedestrian's eyes always are higher than the automobile front lamp position, so just not stimulated by light.Thereby both sides all need not turn off the light, reduce Operating Complexity, and can guarantee meeting and pedestrian's safety again, and be a kind of vehicle meeting light fixture that is better than other scheme.

Fig. 1 is the low shot-light of meeting.Fig. 2 is the state diagram that meets at night.

Claims

1, a kind of vehicle low shot-light that meets at night is characterized in that: the reflective surface (1) of the low shot-light of meeting is to spend the geometrical curve face that forms by the curve rotation 120 that 180 degree circular arcs link to each other with 1/2 parabola to make.

2, the low shot-light of meeting as claimed in claim 1, it is characterized in that: the center of circle and 1/2 parabolic focus of 180 degree circular arcs are on the same point (2).

3, as the low shot-light of claim 1,2 described meetings, it is characterized in that: the light source of low shot-light is installed on the point (2) that center of arc and parabola focus existed together.
