As preferably, described lens body adopts optical grade PMMA or optical grade PC light transmissive material to manufacture.
As preferably, described lens body outer surface both sides are provided with protrusion step.The step at two ends is higher than protruding (optical surface), and protection protruding (optical surface) is not scraped off.
As preferably, the equal correspondence of each LED lamp bead in described LED lamp panel is located at protruding below.Make light pass through protruding optical surface, concentrate and exhale.
As preferably, described lens body inside is provided with the locating dowel for accurately installing main LED body.
As preferably, described locating dowel is positioned at the two ends of lens body, is provided with chamfering bottom locating dowel.Be convenient to LED lamp panel pass, and realize positioning and guiding.
As preferably, described lens body internal edge is provided with groove, places the plastic seal ring for protecting in described groove.
As preferably, the groove outer of described lens body is provided with installing hole.
As mentioned above, the dust-proof module lens of LED lamp of the present utility model, has following beneficial effect:
LED module lens outer surface entirety is the structure (plane is provided with minute protrusions) of a similar plane, protrusion height is only 0.5mm, lens outer surface is not only made not easily to gather grieshoch, even if there is grieshoch also easy wiped clean, greatly reduce the impact of later stage environment factor on light fixture light extraction efficiency.
This optical unit protruding is utilized to carry out secondary light-distribution to the light that LED light source sends, the relation of combining road brightness and illumination, make irradiation area illuminance distribution, dazzle is low, effectively improve the light extraction efficiency of LED illumination lamp, the overall optical efficiency of dust-proof module lens, up to 94%, higher than independent shelled peanut shape module lens (being generally less than 93%), adds transparent shield (about about 88%) far above shelled peanut shape module lens.
Optical design is carried out to the inner sunken face of incidence surface and the protrusion curved surface of exiting surface, utilizes the catadioptric principle of optics, reach the optical requirement of LED lamp application.
