Ultra low-profile Synios E4014 LEDs Increase Freedom of Design

The low-profile rectangular shape of the new Synios E4014 from Osram Opto Semiconductors enables the light from this LED to be injected into light guides so that a wide range of design ideas can be realized. The mid-power light emitting diodes also have an impressively robust plastic package, a very uniform distribution of light, and an excellent price/performance ratio. The LEDs are intended primarily for visually enhancing white goods such as appliances and for lighting systems in vehicles and displays.

The extremely low height of the Synios - only 0.57 mm - and its tiny footprint of 4 mm x 1.4 mm provide the ideal solution for low-profile, elongated luminaires and lighting designs, including display backlighting. The LEDs do not have a lens so they can easily be used for injecting light into light guides. The new E4014 opens up a whole range of design-oriented lighting solutions, such as integration in the glass shelving in refrigerators and other white goods, car interior lighting, and strip lighting on the floors of buses and trains.

Where each of the two light emitting diodes is used depends on the requirements of the particular application. If brightness and color fidelity are mandatory, then Synios at 41 lm and a color rendering index (CRI) of 80 is the right choice. If brightness is not as important, then the Topled with 7.3 lm at 20 mA is an ideal alternative. The color temperatures of Synios are between 4000 and 5000 K and can be tailored perfectly to the particular application. The robust plastic package is one of the benefits of the new Synios LED, in addition to the extremely uniform distribution of light, high efficiency, excellent flexibility and long life of around 50,000 hours. In view of the intended applications, the ESD stability is 5 kilovolts (kV).
