R7L / R8L led lenses

The convex surface is not shiny but has a micro processing to improve the projection of the light

Suitable for Led single diode

Distance between lens and led: From 1 to 3mm

Note:

Plane convex lens shape, convex radius 7 and 8mm respectively

 

 


 

NF-Series

Link: N-Series

Suitable for Led single diode

Distance between lens and led: From 1 to 3mm

Note:

In the lens base there are three holes, diameter 3.0 mm, interaxis 20 mm or 2 holes, diameter 3.0 mm, interaxis 20 mm.

 

 


 

LK-Series

Link: N-Series

Suitable for Led single diode

Distance between lens and led: From 1 to 3mm

Note:

Lenses suitable for very compact lighting applications

 

 


 

D-Series

Link: D-Series

Suitable for C.O.B. Led (COB LEDs are basically multiple LED chips).

Distance between lens and C.O.B: between 5 more than 15mm

 

 

Note:

The angular projection (light opening angle) is mainly dependending on the distance between the LED and the lens and the focal length of the lens itself.

Bench test parameters to define the angle distributions

Edison COB ED 4000K 19x19mm 80CRI 720-1440mA BIN F2403 – L.E.S. 16mm, Distance between the base of the C.O.B. and the flat surface of the lens: 5mm, increasing the distance the angle distribution will decrease

 

 


 

L-Series

Link: L-Series

Suitable for C.O.B. Led (COB LEDs are basically multiple LED chips).

Distance between lens and C.O.B: between 5 more than 15mm

Note:

The angular projection (light opening angle) is mainly dependending on the distance between the LED and the lens and the focal length of the lens itself.

Fresnel led lenses

Link: Fresnel Lenses

Suitable for C.O.B. Led (COB LEDs are basically multiple LED chips).

Distance between lens and C.O.B: between 5 more than 15mm

Note:

Fresnel lenses consist of a series of concentric grooves etched onto one surface. Their thin, lightweight construction, available in small as well as large sizes, and excellent light gathering ability make them useful in a variety of applications. They are most often used in light gathering applications, such as condenser systems or emitter/detector setups.

The Fresnel lens allows the construction of large-size and small optical focal length lenses without the bulk: the thickness and weight of the material needed to build them are lower than in a conventional spherical lens of equivalent dioptric power.

 

 


 

Cylindrical led lenses

Link: Cylindrical Lenses

Suitable for single led or several aligned led

Distance between the base of the lens and the LED equal to or less than the focal distance

Note:

The led light passing through the cylindrical lens expands in a single axis (showing the projection of a line of light if the led is in the right position)
