Abstract
The utility model relates to a polarizing lens for a light-emitting diode (LED) streetlamp. The polarizing lens is suitable to transmit light emitted by an LED according to a preset light path. The polarizing lens comprises a lens body. One surface of the lens body is inwards sunken to form an incident surface, and the other surface of the lens body is outwards raised to form an emergent surface. The emergent surface is formed by symmetrically splicing two arched surfaces. The incident surface is a long and narrow arched surface, and the depth of the incident surface is gradually increased along a length direction. The polarizing lens for the LED streetlamp is simple in structure and convenient to mount and use; the light can irradiate along the preset light path, so that the utilization rate of the light is increased, and light spots irradiating a road are in line with actual needs.
Description
Technical field
The utility model relates to technical field of lamps, relates in particular to a kind of spreadlight lens of LED street lamp.
Background technology
Nowadays; Street lamp has been the lighting apparatus that is seen everywhere in the cities and towns; It has experienced veryer long development course, up to now, and along with deepening continuously of country and the social energy-saving and emission-reduction theory of advocating; Advantage such as energy-conservation, efficient, stable and environmental protection has been applied in the middle of the street lamp LED more and more with it, and the LED street lamp is being played the part of more and more important role.
The transitional street lamps lens are symmetrical street lamp lens; When installing, need reach the road lighting effect, make the part light intensity loss simultaneously, bring inconvenience for like this installation of installation personnel through the adjustment light fixture elevation angle; Strengthen workload, illuminating effect is also still undesirable.
The utility model content
The main purpose of the utility model is, a kind of spreadlight lens of LED street lamp is provided, and the light that LED is produced can project preposition effectively; Avoided the waste of light; Also reduce the loss of light, can improve the service efficiency of LED widely, practiced thrift electric energy effectively.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme.
The spreadlight lens of the LED street lamp of the utility model; The light that is suitable for LED is sent is by the predetermined light paths transmission, and said spreadlight lens comprises the mirror body, and the one side indent of said mirror body forms an incidence surface; The another side evagination of mirror body forms an exiting surface; Said exiting surface is spliced by two arcwall faces symmetrically, and said incidence surface is the cambered surface of thin-and-long, and the said incidence surface degree of depth along its length is gradually setting deeply.
Preferably, said LED extend in the said incidence surface.
Preferably, said incidence surface is provided with frosting in the bosom.
Preferably, said incidence surface is an ellipsoid.
Preferably, said incidence surface is provided with frosting near an end of major axis, and an end of said frosting is positioned at the bosom of said incidence surface.
Than prior art, the LED street lamp spreadlight lens of the utility model is simple in structure, easy to install, can make light along predetermined light path irradiation, thereby improves the utilization rate of light, and the hot spot that is radiated on the road is corresponded to actual needs more.Can make hot spot be symmetrical distribution in its mounting points both sides after the utility model is installed on road, be asymmetric distribution, use desired irradiation distance to regulate the off-centre and the moulding of lens according to reality along vertical road direction along road direction; The promptly actual irradiation distance that requires is far away more, and the numerical value of this eccentricity of region is big more, and this structure just has been equivalent to form the convex lens of an off-axis; Reach the purpose that light tilts; Lens are the curved surface of two symmetries, and through two semi-surfaces that the LED optical axis separates, there is certain eccentric throw in its bifocal; Scioptics are regulated the light distribution of light, make that also the illumination that is radiated on the road surface is more even.
Description of drawings
Fig. 1 is the sectional structure sketch map of spreadlight lens among the embodiment of the utility model;
Fig. 2 is the sectional structure sketch map of spreadlight lens among another embodiment of the utility model.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Below will combine accompanying drawing and specific embodiment to specify the technical scheme of the utility model, so as clearer, understand its invention essence intuitively.
Fig. 1 is the sectional structure sketch map of the spreadlight lens of present embodiment.
With reference to shown in Figure 1, the described LED street lamp of present embodiment spreadlight lens 100 is mainly used in and covers on LED, with light that LED is sent by predetermined light path transmission.Spreadlight lens 100 comprises that the one side indent of mirror body 1, mirror body 1 forms an incidence surface 2, and the another side evagination forms an exiting surface 3.Incidence surface 2 is long and narrow cambered surface, and exiting surface 3 is spliced by two arcwall faces symmetrically.LED extend in the above-mentioned incidence surface 2, and to incidence surface 2, light is penetrated by above-mentioned exiting surface 3 after reflection and refraction with ray cast.
The utility model for the light that makes LED and send behind spreadlight lens 100, can penetrate by predetermined light path, also design following structure.
Fig. 2 is the sectional structure sketch map of spreadlight lens in the present embodiment.
With reference to shown in Figure 2, the incidence surface 2 of present embodiment is caved inward by mirror body 1 and forms, and incidence surface 2 degree of depth along its length is gradually setting deeply.
In addition, after making the light transmission, can evenly disperse, the above-mentioned incidence surface 2 of present embodiment is set to ellipsoid.The degree of depth of this ellipsoid on mirror body 2 is all inequality throughout.Particularly, incidence surface 2 has a major axis, is gradually dark situation along its long axis direction (also being length direction), make an end of major axis the darkest, and the other end is the most shallow, and the centre seamlessly transits.Wherein, be provided with at a darkest end and can form irreflexive frosting 21.Like this, when ray cast that LED sends to incidence surface 2 during a darkest end, set frosting 21 reflects this light, makes it see through mirror body 1 by other position, makes light can not go out and all project in effective irradiated area from this direction transmission.Avoid the waste of light on other direction.
Can know that from the above the LED street lamp spreadlight lens of the utility model is simple in structure, easy to install, can make light, thereby improve the utilization rate of light, the hot spot that is radiated on the road is corresponded to actual needs more along predetermined light path irradiation.For example, can make hot spot be symmetrical distribution in its mounting points both sides after the LED street lamp that will contain the utility model is installed on road, and be asymmetric distribution along direction perpendicular to road along road direction; Use desired irradiation distance to regulate the eccentric throw and the moulding of lens according to reality; The promptly actual irradiation distance that requires is far away more, and the numerical value of this eccentricity of region is big more, and this structure just has been equivalent to form the convex lens of an off-axis; Reach the purpose that light tilts; Lens are the curved surface of two symmetries, and through two semi-surfaces that the LED optical axis separates, there is certain eccentric throw in its bifocal; Scioptics are regulated the light distribution of light, make that also the illumination that is radiated on the road surface is more even.
The above is merely the preferred embodiment of the utility model; Be not so limit its claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
