Description
Technical field
The present invention and lighting apparatus especially relate to a kind of lighting with anti-dazzle arrangement.
Background content
These three kinds of lightings of street lamp, headlight for vehicles and Down lamp are when producing effective illumination beam, and the refractive body of taper has caused above reverberation of secondary and uncontrollable scattered light to form dazzling dazzle because of process of surface treatment can not meet design requirement.Though the light of street lamp is very soft, can illuminate road to passerby, the dazzle meeting that it produces makes the people not see road, is one of the main light pollution source in city; Because the brightness of headlight for vehicles is more than the street lamp height, so it is stronger, more dazzling than the dazzle of street lamp in the dazzle that effective irradiates light of taper is peripheral upwards, outside, thereby when automobile meeting, irradiated driver in opposite and pedestrian usually at the moment a slice grow dim, just do not see front link and vehicle condition at all, usually cause operating mistake, as easy as rolling off a log generation traffic accident in flurried; The Down lamp of One's name is legion is usually used in the interior decoration, and present original Down lamp has all adopted reflection shield to control irradiation area, but the factor amount is numerous, still causes strong dazzle easily, and without the secondary non-glare treated, the dazzle of its generation also be can not ignore.As seen, irradiation light X1-X2 zone is reasonable range of exposures from accompanying drawing 1,2,3, the dazzle light beam scope of irradiation light X1-D1, X2-D2 zone for getting rid of.
The patent No. is 02142339.3 patent of invention: the automotive anti-glare lamp is to adopt grating to come anti-dazzle, and this structure light loss is bigger, and structure is also complicated, does not implement meaning widely.
Summary of the invention
The object of the present invention is to provide a kind of with illumination beam be controlled in effective lighting scope and the critical projectional angle fully, make effective lighting scope illumination more even, and the dazzle light beam can be changed direction and become the lighting that effective irradiates light, anti-dazzle are effective, can effectively eliminate the band anti-dazzle arrangement of light pollution.
The object of the present invention is achieved like this: the present invention includes lamp housing, reverberation bowl, bulb and lampshade, feature is in the bulb front anti-dazzle arrangement to be installed.
Described anti-dazzle arrangement is made up of convex lens, concavees lens and columnar darkening ring, the left end of darkening ring is fixedlyed connected with the right-hand member of lamp housing, convex lens and concavees lens all are installed in the darkening ring side by side, convex lens are installed in the inside in the darkening ring and near bulb, concavees lens are installed in the outside in the darkening ring.Inwall the latter half at darkening ring scribbles dark light-absorption layer.
Described anti-dazzle arrangement is made up of simple lens, and simple lens is installed between bulb and the lampshade, and the illuminator of signal-lens axis and bulb is on the same straight line.Described simple lens is a kind of in single convex lens or the single concavees lens.
Described anti-dazzle arrangement is that concavees lens/convex lens, periphery are formed for the compound lens of ring-like prism by the centre, and compound lens is installed between bulb and the lampshade, and the illuminator of the axis of compound lens and bulb is on the same straight line.
Described anti-dazzle arrangement is made up of the dust cover of the outer ennation of reverberation bowl, dark light-absorption layer and straight or indent, scribbles dark light-absorption layer at the outer ennation taper ends inside part of reverberation bowl.Light fixture extends 0.6 times of lateral dimension of light source more than or equal to the outer ennation that is reverberation bowl apart from the distance of dust cover, and the tapering of reverberation bowl is less than critical projectional angle.
The applicant is through theoretical research for many years and practice, invented dazzle principle analysis theory, the differentiation of distinct dazzle light beam and non-dazzle light beam is the notion of critical projectional angle, and promptly critical projectional angle is meant in the Design of Luminaires of projection from the top down, the crevice projection angle that light should be controlled.When light is invested ground greater than critical projectional angle, there is part light (being dazzle) can directly inject eyes down at normal visual angle (looking squarely); During only less than critical projectional angle, all light just can directly not injected eyes under normal visual angle (looking squarely), can not produce dazzle.(seeing Figure 13).
The computing formula of described critical projectional angle Φ is: tag Φ=C/ (A-B), and wherein A is the distance of street lamp to ground, and B is the health height of test person, and C is that human body is to the vertical range of light source perpendicular to the ground straight line.
The present invention is according to above-mentioned theory and utilize light will produce refraction principle between the material of close property of light and the thin property of light, dark light-absorption layer light-absorbing principle of energy and critical projectional angle principle after tested, design has anti-dazzle arrangement in light fixture, promptly adopt anti-dazzle arrangement to control the lighting angle or the zone of light fixture, satisfy the requirement of critical projectional angle, anti-dazzle arrangement can be controlled at illumination beam fully in the effective lighting scope and critical projectional angle of overtesting and test like this, make effective lighting scope illumination more even, and dazzle light beam change direction can be become effective irradiates light, anti-dazzle is effective, thereby can effectively eliminate the purpose that light pollution has reached anti-dazzle, as:
1, headlight for vehicles is after installing the anti-dazzle arrangement of being made up of convex lens, concavees lens and columnar darkening ring additional, bulb is when producing effective illumination beam, scattered light in effective irradiates light periphery of taper has also become dazzling dazzle, change direction after the refraction of dazzle light beam process double lens (convex lens and concavees lens) and become effective irradiates light, upwards the dazzle light beam of reflection is then absorbed by light-absorption layer, no longer become dazzling dazzle, avoided dazzle pedestrian and other drivers;
2, Down lamp install additional by single convex lens or single concavees lens or centre be concavees lens/convex lens, the peripheral anti-dazzle arrangement of forming for the compound lens of ring-like prism after, the dazzle light beam changes direction after through simple lens (convex lens or concavees lens) or middle refraction for concavees lens/convex lens, peripheral compound lens for ring-like prism and becomes effective irradiates light, and the control light beam is less than investing ground in the critical projectional angle, reach the purpose of anti-dazzle, make effective lighting scope illumination more even, eliminated light pollution;
3, street lamp installs original reverberation bowl additional outer ennation, and scribbles dark light-absorption layer at the outer ennation taper ends inside part of reverberation bowl.Invest ground less than critical projectional angle under the light beam control of ennation outside, dark light-absorption layer can not fall because of manufacture craft reaches the dazzle beam absorption that requires to cause, and only keeps the effective illumination beam in the taper, thereby reaches the purpose of anti-dazzle.
Thereby therefore the present invention have with illumination beam be controlled at fully in the effective lighting scope and critical projectional angle of overtesting and test, make effective lighting scope illumination more even, and the dazzle light beam can be changed direction become effective irradiates light, anti-dazzle effective, can effectively eliminate purpose that light pollution reaches anti-dazzle, can greatly improve people and use the euphorosia of lighting apparatus, effectively eliminate the advantage of light pollution, simple in structure, handling ease.
