Notes on LED Illuminated Units
LED lamps consist of semiconductors. If the applied voltage
exceeds the rated voltage, LED elements may deteriorate
due to overheat, resulting in significant decrease in lumi-
nance, hue change, or failure of lighting. Also, if an extrane-
ous noise, transient voltage, or transient current is applied to
the circuit, similar effects may occur. When using LED
lamps, observe the following instructions.
The LED lamps are rated at 6V, 12V, or 24V AC/DC, and can
be used within ±10% the rated voltage of either AC or DC.
1. Switching power supply
2. Rechargeable battery
3. Full-wave rectification
4. Single-phase half-wave rectification
LED elements deteriorate due to extraneous noise, resulting
in significant decrease in luminance, hue change, or failure
of lighting. When such effects are anticipated, take a protec-
tion measure shown below, such as RC elements or a surge
absorber.

subjected to noise.
Regulated voltage from switching power supply is best
suited. Make sure to use within the rated voltage of the
LED lamp.
Note that the battery voltage may exceed the rated volt-
age of the LED lamp while the battery is being charged
and immediately after the charging is complete. Be sure
to use the LED lamp on a voltage of ±10% the rated volt-
age.
Since the LED lamp is AC/DC compatible, a diode bridge
for rectification is not necessary. If the LED lamp is used
on a full-wave rectification current through a diode bridge,
the rectifier diodes will reduce the voltage, resulting in
lower luminance.
This is not suitable for the power source of LED lamps.
Use constant-voltage DC power.

[Circuit Example]
Connect shunt resistor R in parallel with the LED lamp.
–
Do not use the pure white LED outdoors, otherwise it will
lead to the degradation of brightness and color. Do not
remove or apply shock to the cap on the pure white LED
lamp, otherwise it may break or damage the cap.
For the pure white LED, use a white lens. The illumination
color will be dull if a different color is used.
