Abstract

The utility model discloses an anti-glare directional reflection bowl in a car lamp area, which comprises a bowl-shaped lamp shade body; the bowl-shaped indent surface of the lamp shade body is a reflecting surface; the part in the bowl-shaped reflecting surface, which causes glaring reflected light, is provided with reflecting ridges which extend on the periphery thereof and are arranged zigzag; each reflecting ridge is provided with two reflecting surfaces; an external reflecting plane is a backlight surface and the reflecting angle thereof is a horizontal light-emitting angle or a downward light-emitting angle which does not cause glare; and due to the reflecting angle of an internal reflecting plane, light is reflected to the upper part and lower part of the reflecting bowl but not the outside of the reflecting bowl. When the car lamp is turned on, due to the zigzag reflecting ridges on the reflecting surface of the lower half part, the anti-glare directional reflection bowl reflects forward and upward reflecting light back to the upper part and the inner part of the reflecting bowl, and maintains forward and slantingly downward light simultaneously, thus being capable of illuminating the ground, controlling the illuminating angle to the maximum and reducing the glaring light at the front upper art, and greatly improving traveling safety.

Description

Anti-glare car light zone directional reflective bowl

Technical field

The utility model relates to a kind of illuminace component, relates in particular to a kind of anti-glare reflector lamp bowl.

Background technology

Car light is exactly vehicle " eyes ", it is the guarantee of vehicle safe driving, but but car light itself can become safe hidden danger sometimes, because vehicle tends to open headlamp and helps the driver to see pavement behavior clearly in the dim environment in road surface as everybody knows, but headlamp has individual problem, and to be exactly it to the place ahead tend to cause to the irradiation of upper angle that opposite meeting driver, pedestrian's dazzle the eyes, temporarily do not see road surface at the moment, cause potential safety hazard, this problem all is everybody but the difficult problem that can't properly settle of puzzlement all the time.

As shown in Figure 1, the upwards reverberation of the latter half reflective surface is exactly to cause the light of dazzling the eyes in the reflector.

The utility model content

Technical problem to be solved in the utility model provides a kind of anti-glare car light reflector, can reduce the irradiates light that the place ahead makes progress to greatest extent when car light is opened, thereby is dazzling the eyes according to avoiding under the prerequisite on road surface, clear the place ahead meeting driver to the opposite to cause.

The utility model is for solving the problems of the technologies described above

A kind of anti-glare car light zone directional reflective bowl, comprise a bowl-shape lampshade main body, its bowl-shape inner concave is a reflective surface, the reflection rib that the zigzag that causes the part of dazzle reflexes light to be provided with in described bowl-shape reflecting surface to circumferentially extend is arranged, the reflective rib of each bar has two planes of reflection, the external reflectance plane is that its reflection angle of shady face is not cause the flat fire angle or the following firing angle degree of dazzling the eyes, and the reflection angle of interior reflective surface is top and the inner outside do not reflected to reflector of reflection to reflector.

Cause the part of dazzle reflexes light can be middle part and the latter half of reflecting surface in the wherein said bowl-shape reflecting surface.

Cause the part of dazzle reflexes light also can be the latter half of reflecting surface in the described bowl-shape reflecting surface.

Reflector of the present utility model is when car light is opened, zigzag reflection bar design because of its latter half reflecting surface, with the original reverberation that made progress forward reflected back reflector top, inside again, kept reflector simultaneously forward and the light under tiltedly, so just can be when keeping the road surface irradiation, control irradiating angle to greatest extent, reduce the glaring light of front upper place, improve traveling security greatly.

Simultaneously, because behind the light reflected back reflector top of reflector of the present utility model with the latter half, convert the downward forward light of illumination angle to, reduced the loss of front upper place to useless light, the exposure intensity of irradiating angle under before having strengthened, so under the situation that does not increase light source power, the brightness of light is improved to some extent again.

Description of drawings

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, wherein:

Fig. 1 is the structural representation of car light reflector in the prior art;

Fig. 2 is one of structural representation of the utility model anti-glare car light zone directional reflective bowl;

Fig. 3 be the utility model anti-glare car light zone directional reflective bowl structural representation two;

Fig. 4 is the enlarged drawing of A part among Fig. 2.

Among the figure:

1. reflect rib 11. external reflectance planes

12. interior reflective surface 3. internal light sources

The specific embodiment

Fig. 2, Fig. 3, Fig. 4 shows anti-glare car light of the present utility model zone directional reflective bowl, comprise a bowl-shape lampshade main body, its bowl-shape inner concave is a reflective surface, the latter half in described bowl-shape reflecting surface is provided with the reflection rib 1 of the zigzag arrangement that circumferentially extends, the reflective rib of each bar has two planes of reflection, external reflectance plane 11 is not cause the flat fire angle (also can be downward slightly following firing angle degree) of dazzling the eyes for its reflection angle of shady face, the reflection angle of interior reflective surface 12 is top and the inside of reflection to reflector, and not reflecting outside to reflector, interior reflective surface 12 becomes 36 ° of angles (being that reflecting surface 12 becomes 36 ° of angles with the axis of reflector) with the front irradiation direction of reflector.

Described interior reflective surface 12 also can be other angle with the formed angle of front irradiation direction of reflector, for example 30 °, 40 °, 45 ° etc., as long as the reverberation reflection that light makes interior reflective surface 12 in using is to the top of reflector and inner and do not reflect outside to reflector.

Same, because the shape of reflector can be other shape, and also there is different requirements in the anti-glare irradiating angle, so the above-mentioned zone that the reflection rib 1 of zigzag arrangement is set also can be middle part and the latter half of bowl-shape reflecting surface, or other band of position, as long as dazzle reflexes light can be caused in this zone.

When internal light source 3 irradiations, front vehicles, personnel's the irradiation of dazzling the eyes promptly can be caused in the front upper place of the reverberation directive car light of its latter half reflecting surface as the reflector of prior art among Fig. 1.

And after having used reflector of the present utility model, internal light source 3 is reflecting on the interior reflective surface 12 of rib 1 to the irradiates light direct irradiation of downside, reflection is outside again after the upper interior portion of reflector through interior reflective surface 12 reflections, and this moment, its irradiating angle was not formed the forward lower comer degree of glaring light after the reflection conversion.
