Abstract
The utility model belongs to the vehicle lighting equipment, which is composed of a parabolic cylindrical surface reflecting lamp cover 1, a strip lamp 2, a high beam straight-line filament 3, a short-distance beam straight-line filament 4 and a lamp holder 5. The high beam has no scattering illumination system and achieves the purpose of anti-dazzling. The utility model has simple technique and structure, low cost, convenient adjustment, and favorable anti-dazzling effect, and can be manufactured by common automobile parts plants.
Description
The utility model relates to a kind of parabolic cylinder light source novel illumination light fixture on schedule, and it belongs to the lighting device class of vehicle.
Existing Vehicular illumination device can't overcome the light scattering phenomenon when using, and when making automobile meeting, the anti-glare problem is not solved.
Its technical essential of antiglare headlamp that CN87215157 announces is the numerical information that obtains the space curved surface of primary reflection surface by mathematical method, and reflecting surface is with the one-to-one relationship of each point of irradiation on each pip and the headlamp exposure field on the acquisition curved surface on assisting again.This method, the one, design, complicate fabrication process, the 2nd, the light that filament sends can only provide directional light approx to primary reflection surface, still has scattering to dazzle the eyes phenomenon.
The technical essential of the headlamp that CN87211342 announces is to have increased a hemispherical reflective mirror on the common vehicle high beam, and a light is reflected from former road, and the light that lamp is sent can only penetrate forward or downwards.Its scattering is not really solved to still have dazzles the eyes phenomenon.
The purpose of this utility model provides the accurate focus light source of a kind of parabolic cylinder novel illumination light fixture, and it need not to adopt the lucifuge device to make light beam not have the parallel ejaculation of scattering with light distribution device to reach dazzle-free effect.
Technical essential of the present utility model is that filament is not traditional space curve but a complete linearity, and the parabolic spherical that primary reflection surface neither be traditional but parabolic cylinder makes the collimated light beam that penetrates no scattering is with dazzling the eyes of solution headlamp.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1: structural representation of the present utility model.
Accompanying drawing 2: accompanying drawing 1 to view.
With reference to accompanying drawing, light fixture by headlight high beam filament 3, dip filament 4 are arranged in lamp socket 5, the fluorescent tube 2(), parabolic cylinder reflection lampshade 1 forms. Distance light straight line filament is positioned on the focal line of parabolic cylinder, and the light that filament is sent is penetrated by the collimated light beam that the parabolic cylinder lampshade is reflected into no scattering, reaches good anti-dazzle effect. (dip filament though folded light beam has scattering to following, can not dazzle the eyes phenomenon yet on headlight high beam filament).
Outstanding advantages of the present utility model is simple in structure, and is easy to manufacture, and installation and debugging are convenient, and anti-dazzle effect is good, be convenient to large-scale popularization.
Claims (4)
1, the accurate focus light source of a kind of parabolic cylinder novel illumination light fixture is characterized in that the no scattered reflection collimated light beam system that is made of long fluorescent tube of straight line filament and parabolic type cylinder reflection lampshade 1.
2, by the lighting of claim 1, it is characterized in that filament 3,4 must be entirely a linearity.
3, by the lighting of claim 1, the reflecting surface that it is characterized in that lampshade 1 must be the parabolic cylinder shape.
4, by the lighting of claim 1, when fluorescent tube 2 is installed, headlight high beam filament 3 must be positioned on the focal line of lampshade reflecting surface, dip filament 4 is above headlight high beam filament.
