It is made of curved surface, the light-emitting surface is protrusion curved surface, is made of more than one free form surface, the free form surface passes through circle
It slips over and crosses connection.The incidence surface and light-emitting surface of protrusion are optical surface, realize that the main of light penetrates.
Preferably, the lens body is manufactured using optical grade PMMA or optical grade PC translucent materials.
Preferably, lens body outer surface both sides are equipped with protrusion step.The step at both ends is than raised (optical surface)
It is higher, protect raised (optical surface) not to be scraped off.
Preferably, each LED lamp bead in the LED lamp panel is correspondingly arranged at below protrusion.It is convex so that light passes through
The optical surface risen, concentration exhale.
Preferably, the lens body is internally provided with the positioning column for accurately installing main LED body.
Preferably, the positioning column is located at the both ends of lens body, positioning column bottom is equipped with chamfering.Convenient for LED lamp panel
It passes through, and realizes positioning and guiding.
Preferably, the lens body internal edge is equipped with groove, placed in the groove close for the plastics of protection
Seal.
Preferably, the groove outer of the lens body is equipped with mounting hole.
As described above, the dust-proof module lens of LED lamp of the present invention, have the advantages that：
The structure (plane is equipped with minute protrusions) of the similar plane of LED module lens outer surface generally one, protrusion is high
Degree is only 0.5mm, not only makes lens outer surface be not easy to gather grieshoch, but also be easy wiped clean having grieshoch, greatly
Reduce influence of the later stage environment factor to lamps and lanterns light extraction efficiency.
Secondary light-distribution, combining road brightness and photograph are carried out to the light that LED light source is sent out using this raised optical unit
The relationship of degree makes irradiation area illuminance distribution, and dazzle is low, effectively increases the light extraction efficiency of LED illumination lamp, dust-proof mould
The whole optical efficiency of group lens is up to 94%, higher than independent shelled peanut shape module lens (being generally less than 93%), far above flower
Raw rice shape module lens add transparent shield (about 88% or so).
The protrusion curved surface of inner sunken face and light-emitting surface to incidence surface carries out optical design, utilizes optical catadioptric original
Reason reaches the optical requirement of LED lamp application.
