Description
Technical field
The utility model relates to a kind of lens, specifically is a kind of LED street lamp lens.
Background technology
Chinese patent document number CN101173742 discloses a kind of LED street lamp of large illumination range on May 7th, 2008, belongs to field of illumination lamp technology.It is characterized in that being equipped with in the lamp body chamber convex surface luminous plaque; Convex surface luminous plaque inner surface is provided with fin; The lamp socket bottom that is provided with on the convex surface luminous plaque outer surface connects the LED lamp, and the lamp socket bead is equipped with optical lens, and the connection of lamp body bead surface is provided with transparent lamp shade.The present the most desirable light-configuration mode of high-power LED (Light Emitting Diode) road illuminating is a Batwing type rectangle luminous intensity distribution, is the energy-conservation greater advantages of performance LED, improves the utilization rate of light, reduces the input cost of street lamp, is necessary the LED road lamp light distribution is further improved.
The utility model content
The purpose of the utility model aim to provide a kind of simple and reasonable, improve LED street lamp irradiated area, satisfy the LED street lamp lens that related road illumination standards requires illuminance and the uniformity, to overcome weak point of the prior art.
A kind of LED street lamp lens by this purpose design comprises the lens that are installed on the led light source, and both axis are on same straight line; Said lens comprise a upper surface and a bottom surface; Its architectural feature is that upper surface is the non-sphere curved surface of strip of top evagination, extends outward connecting portion around the bottom surface, and the middle part indent has the strip curved surface; The non-sphere curved surface of strip moves towards about being, the strip curved surface is the front and back trends.
The lateral cross section of the non-sphere curved surface of strip of said upper surface is half capsule shape, and the longitudinal cross-section of the strip curved surface of bottom surface is half capsule shape.
Be provided with the boss platform between the bottom of the non-sphere curved surface of said strip and the connecting portion, there is the rectangular recess that links to each other with the strip curved surface at bottom surface middle part also indent.
Said connecting portion is the plane abduction edge along the bottom surface bottom margin extends outward.
Said lens form through the compacting of optics heatproof glass.
The lens of the utility model form through the compacting of optics heatproof glass; Heatproof and light transmittance are high, at utmost reduce the loss of light, and the light that led light source is sent is fully used; The light that led light source sends is through behind these lens; Produce the rectangle luminous intensity distribution of Batwing type, it is long-pending to improve rectangular irradiated face, satisfies related road illumination standards to illuminance and uniformity requirement.These lens for the power that increases street lamp, illuminance etc., can adopt several lens mode arranged in a straight line to install in use, and assembling, easy to maintenance helps producing and using on a large scale.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 8, this LED street lamp lens comprises the lens 23 that are installed on the led light source 22; Both axis are on same straight line, and said lens 23 comprise a upper surface and a bottom surface, and its upper surface is the non-sphere curved surface 1 of the strip of top evagination; Extend outward connecting portion 5 around the bottom surface; The middle part indent has strip curved surface 3, and the non-sphere curved surface 1 of strip moves towards about being, strip curved surface 3 is the front and back trends.
The lateral cross section of the non-sphere curved surface 1 of the strip of upper surface is half capsule shape, and the longitudinal cross-section of the strip curved surface 3 of bottom surface is half capsule shape.Be provided with boss platform 2 between the bottom of the non-sphere curved surface 1 of strip and the connecting portion 5, there is the rectangular recess 4 that links to each other with strip curved surface 3 at bottom surface middle part also indent, is used for empty avoiding led light source 22.
Connecting portion 5 is used to install and fix lens 23 for along the plane abduction edge that the bottom surface bottom margin extends outward.Lens 23 adopt light transmittance greater than 97%, and refractive index forms for the compacting of (1.5-1.7) optics heatproof glass, and it is more durable to compare other materials, more can improve the efficiency of transmission of light energy.
With reference to Fig. 8; During actual installation, led light source 22 sticks on the cooling base 21, and lens 23 are through metal or plastics fixed cap 24 (its shape and lens 23 edge contours; Be that connecting portion 5 is consistent) be fixed on the installed surface of cooling base 21; Also can place high temperature resistant, aging-resistant silicone rubber O-ring (not marking among the figure) between the connecting portion 5 of fixed cap 24 and lens 23, further fixed lens 23 is simultaneously to 22 waterproof effect of led light source.
Because LED (comprising the integrated form great power LED) is a kind of lambert's type light source, and road lighting requires lamp distribution to be preferably Batwing type rectangle luminous intensity distribution, makes on the road few shade or shadow-free between the lamp and lamp.Utilize light through two kinds of different dielectric interfaces the time, can produce the principle of refraction and reflection, make lambert's type light source when getting into the optical system (lens) that technical scheme of the present invention provided, light is through specific plane of refraction; Irradiate light on the shadow surface of needs; Simultaneously, the bottom of present embodiment lens 23 further is provided with groove, can change the wherein refraction angle of plane of light incidence; Pass through said method; Irradiation area meets light distribution requirements in the road surface to make light, and obtains amassing than the rectangular irradiated face of broad, has improved the utilization rate of light.
