LEDiL Martha 系列 中角度 LED 透镜 C10436_NIS83-MX-3-M

LEDiL MARTHA Series LED Lenses

The MARTHA series from LEDiL, are a family of round LED lenses with a diameter of 50 mm. These multi-lens arrays are designed for use with three LEDs. They have a clear or diffused lens and offer a range of beam types from a spot to wide angle. MARTHA lenses direct the light from an LED light source through the lens to achieve the desired beam emission type with a uniform output.
Made using an optical grade PMMA, the MARTHA lenses offer a high UV and temperature resistance. They fasten into place using positioning pins and glue.
MARTHA lenses have been designed and optimised for use with a variety of LEDs. Due to the rapidly changing nature of LED products customers are strongly advised to consult the latest manufacturer data for compatible LEDs.

注

The viewing angle produced (the full angle measured at the half peak luminous intensity value) will vary depending on the chip size, colour and position of the LED.
