Abstract
The utility model discloses a novel light-emitting diode (LED) street lamp lens structure for a slope road surface. The LED street lamp lens structure comprises a lens which is arranged outside an LED light source, and a concave lens part is formed in the lens. A vertical plane which transversely penetrates through the slope road surface and passes through the lighting center of the LED light source is used as a reference plane, and the center point of the concave lens part is deviated from the reference plane. According to the novel LED street lamp lens structure for the slope road surface, due to the fact that the center point of the concave lens part is deviated from the reference plane, the deviating angle can be designed to be matched with the actual gradient of a slope where the street lamp is placed, the connecting line of the center point of the concave lens part and the lighting center of the LED light source is enabled to be perpendicular to the slope road surface, the light scattering characteristic of the concave lens is utilized, the light intensity, at the position perpendicular to the slope road surface, of the LED light source is enabled to reach the minimum, the light intensity on two sides gradually becomes larger, and therefore the illumination evenness of the entire slope is achieved. Meanwhile, the straight lamp does not need to be roughly mounted in an adaptability mode along the slope, and mounting is convenient. The entire street lamp does not need upwarping along the slope, the light does not affect the sight line of a person who walks down the slope, and safety and practicability are achieved.

In order to achieve the above object, the utility model adopts such technical scheme:
A kind of Novel LED street lamp lens arrangement that is used for the road surface, slope for the road surface, slope comprises being located at the outer lens of led light source that the inboard of described lens is provided with the cambered surface cavity that holds led light source, and described lens are formed with concavees lens portion; Crossing the road surface, slope and the perpendicular by the led light source centre of luminescence is datum level, the central point of described concavees lens portion departs from described datum level.
Above-mentioned concavees lens portion forms by being arranged with in the pit of said lens outer surface and the thin location between the above-mentioned cambered surface cavity.
The central point of above-mentioned concavees lens portion and the line of the led light source centre of luminescence equal the gradient number of degrees on the residing slope of street lamp with the angle number of degrees of above-mentioned perpendicular.
Said lens has the fixed base plate that is fixed on the pcb board.
Said lens has the fixed base plate that is fixed on the pcb board.
Said fixing base plate and said lens are structure as a whole.
The said fixing base plate has the reference column that embeds pcb board.
The said fixing base plate is square, the place, four angles of four described fixed base plates in above-mentioned reference column office.
Above-mentioned cambered surface cavity deflection is away from road one side setting.
Said lens is length along half American football shape of road bearing of trend.
After adopting technique scheme, Novel LED street lamp lens arrangement for the road surface, slope of the present utility model, on lens, be formed with concavees lens portion, to cross the road surface, slope and the perpendicular by the led light source centre of luminescence is datum level, the central point of concavees lens portion departs from described datum level, this angle that departs from can be mated design according to the actual grade on road surface, street lamp slope of living in, make the line of the central point of concavees lens portion and the led light source centre of luminescence perpendicular to the road surface, slope, utilize the astigmatic characteristic of concavees lens, make the light intensity of led light source at vertical slope place reach minimum, both sides become greatly gradually, thus reach the LED street lamp to whole domatic illumination evenly; Also can make street lamp needn't carry out coarse adaptability along the slope simultaneously and install, unified mounting means, installation parameter is held easily, and is simple and convenient; And whole street lamp needn't be upturned along the slope, the eyes that the light that led light source sends can direct projection descending person, and the person's sight line that can not influence the descending, safe and practical.
