EL Backlighting

A Cold Light Source

Visipoint EL Lamps are a very thin, electrically stable, ‘cold’ lighting medium. The EL Lamp comprises a polyester substrate which is selectively applied with a phosphor/dielectric combination essentially forming a parallel plate capacitor.

EL Lamps are an alternative to conventional lighting techniques such as LED's and fibre optics, and have become increasingly used in a wide range of sophisticated electronic applications especially where minimum thickness is critical to a design.

As we manufacture our EL lamps in-house we can custom design them to suit your requirements. We are able to tailor the shape and even include cutouts within the lamp to allow an exact fit for your application. We can selectively apply (i.e. to light only where backlighting is needed) the EL materials to the lamp allowing lower costs to be realised whilst maximising illuminated area and minimising power consumption.

How Long Will it Last?

In normal operation, EL Lamps can be expected to perform with an acceptable level of brightness greater than 5000 hours. The life of the lamp is directly dependant on the voltage, frequency, temperature and humidity at which it is driven. Devices which only require low illumination levels can expect longer life from the lamp than those with higher requirements. The brightness of the lamp will decay in a linear fashion from initial power up.

EL Inverters

We have a range of inverters available to drive our EL Lamps. Please see the specifications for more information on the options available.
