51 / 51 page  78 ø30 ø30 Series Instructions Installation of LED Illuminated Units 1. Note the polarity for wiring when connecting to DC-DC converter unit. Terminal No. Polarity X1 Positive X2 Negative 2. Transformer units are recommended for use in areas subjected to noise. 3. Notes for Pure White LED Lamps •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. 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 luminance, hue change, or failure of lighting. Also, if an extraneous noise, transient voltage, or transient current is applied to the circuit, similar effects may occur. When using LED lamps, observe the following instructions. Rated Voltage 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. DC Power 1. Switching power supply Regulated voltage from switching power supply is best suited. Make sure to use within the rated voltage of the LED lamp. 2. Rechargeable battery 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 voltage. 3. Full-wave rectification 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. 4. Single-phase half-wave rectification This is not suitable for the power source of LED lamps. Use constant-voltage DC power. Noise LED elements deteriorate due to extraneous noise, result- ing in significant decrease in luminance, hue change, or failure of lighting. When such effects are anticipated, take a protection measure shown below, such as RC elements or a surge absorber. [Protection Example 1] For AC circuit LED with transformer LED R C LED Ry Relay coil or solenoid R C LED with transformer (Reference values) R: 120 C: 0.1 F [Protection Example 2] For DC circuit Ry LED Diode Relay coil or solenoid + – (Reference values of the diode) Forward current: More than the Ry coil current Reverse withstand voltage: Ry coil current ¥ 10 Countermeasures against Dim Lighting 1. Leakage currents through the transistors or a contact protection circuit may cause the LED lamp to illuminate dimly even when the output is off. 2. When the LED lamp is illuminated by a transistor output, take the following measure. [Circuit Example] Connect shunt resistor R in parallel with the LED lamp. R Io Io: Leakage current when the output is off R: Shunt resistor LED (14/03/18) |
