Light-emitting diodes (LEDs) are P–N junction semiconductors with mechanisms called “junction electro-luminescence.” Appli-
cation of direct current results in radiation or emission of a monochromatic light.
Different semiconductor materials produce different wavelengths of light as shown below:
Advantages of Using LEDs
IDEC Recommendations
For optimum results, especially when using switches and pilot lights in operating environments which are conducive to over-
heating, use IDEC LED illuminated units. Transformers are available for use with incandescent illuminated units, which operate
at lower voltages to avoid overheating.
When IDEC’s L-120L lamp is used, make sure ambient temperatures do not exceed 30˚C (86˚F). If
a lamp from another supplier is used, it should be rated for less than 1.8 watts (15mA at 120V AC),
with ambient temperatures as stated above.
Filament-type incandescent lamps operate within the following parameters.
Light output and life expectancy depend on operating voltage. Light output varies to the 3rd or 4th power of the voltage. Life
expectancy varies inversely to the 12th power of voltage. In other words, over-voltage of 5% reduces life expectancy by 50%.
Under-voltage of 5% doubles life expectancy at the price of light output efficiency.
Inrush current (initial current through the filament) has an adverse effect on life expectancy. Cold resistance (room temperature)
will have a more detrimental effect than hot resistance to inrush current. Life expectancy of incandescent lamps can be maxi-
mized by reducing occurrences of cold resistance to inrush current.
Continued intermittent flashing will significantly reduce life expectancy. When using an incandescent lamp with a tungsten fila-
ment, flashing will not reduce life expectancy as long as light output does not exceed that of steady burning.
When an incandescent lamp must withstand shock and vibration, use low voltage/high amperage (5–6V/60–120mA) lamps.
These lamps have a short, thick filament with a high resonant frequency.
Provide cooling by using a heat sink, particularly when multiple incandescent lamps are grouped or when air circulation is lim-
ited. Make sure ambient temperatures do not exceed 100˚C (212˚F) for maximum life of incandescent lamps.
