R7L / R8L led lenses
The convex surface is not shiny but has a micro processing to improve the projection of the light
Suitable for single led 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 single led 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 single led diode
Distance between lens and led: From 1 to 3mm
Note:
Lenses suitable for very compact lighting applications
C-Series
Suitable for single led diode and 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:
IODA has developed a new led lens which can increase the light angle emitted from a COB (usually +/- 70°) reaching a value higher than +/- 100°.
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 and 15mm
Note:
The angular projection (light opening angle) depends mainly from the LED distance between 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) depends mainly from the LED distance between the lens and the focal length of the lens itself.

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
THR Project, Design and functionality
Link: THR Projrct
Suitable for single led diode and power leds.
These lenses have a threaded area that allows a simple and quick assembly
Note:
Thanks to the THR (thread) lens project, it is possible to obtain an extremely linear design of the lighting system, as the support can be of the same diameter as the lens.
IODA can create new THR lenses according to the specific needs of the individual project, the profile (curvature) of the lens and the surface finish can be defined by the customer.
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)
