Abstract
The invention aims at providing a lateral light distribution street lamp. After the lamp is installed, light of the street lamp projects along a traveling line of a vehicle, light using efficiency can be improved, glare on a driver is reduced, resolving ability of the driver on objects on a road is improved, and driving safety and comfort are improved.
Description
Technical field
The present invention relates to a kind of along terrain vehicle travel direction side road lamp light fixture.
Technical background
The pupil of eye can be regulated along with the power that enters light.Myosis when the light of direct projection eyes is more intense prevents that light from crossing strong damage retina, and the picture of seeing is dazzling except high light, and the part that other are seen can make because of myosis that image is dim to be blured; The pupil amplification allows more light enter when light intensity weakens relatively, makes the picture of seeing more clear bright.
Existing road lamp, mainly by lamp stand along the road both sides or the intermediate isolating band arrange that road lamp light distribution is symmetrical along vehicle heading, driver's eyes are subject to easily the street lamp forceful rays and disturb, affect the resolving ability of driver's road pavement object, reduced drive safety and comfortableness.
Summary of the invention
The purpose of this invention is to provide a kind of light fixture in the situation of same luminous flux, be asymmetric mode by changing existing road lamp light distribution along the vehicle heading left-right symmetry, make more light invest the travel direction of vehicle, thereby reduce the light intensity that road lamp is invested driver's eyes direction, and raising light enters the angle of driver's eyes, reduce and drive driver's dazzle, improve the resolving ability of driver's road pavement object, improve drive safety and comfortableness.
Main technical schemes of the present invention is:
Light source and side luminous intensity distribution optical system are installed in the road lamp, and light source can use dissimilar light sources, and the side light distributing system can be comprised of reflector, lens etc.

The specific embodiment
Embodiment one
As shown in Figure 1, 2, 3, side luminous intensity distribution reflector 2, light source 3 are arranged in the present embodiment light fixture lamp body 1, light source 3 forms the luminous intensity distribution with side distribution curve flux by reflector 2.
Embodiment two
Shown in Fig. 6,7,8, present embodiment light fixture lamp body 1 ' in be arranged with a plurality of light sources 3 ' and side light-distribution lens 4 of being complementary ', light source 3 ' have the luminous intensity distribution of side distribution curve flux by side light-distribution lens 4 ' formation.
Embodiment three
Shown in Figure 11,12,13, present embodiment light fixture lamp body 1 " in a plurality of light source light sources 3 are arranged " and the side light-distribution lens 4 " and reflector 2 " that is complementary, " formation has the luminous intensity distribution of side distribution curve flux for light source 3 " by side light-distribution lens 4 " and reflector 2.
