APPARATUS AND METHOD OF HARMFUL INSECT ILLUMINATING USING DIGITAL DIMMING OF LED

摘要

PURPOSE: An apparatus and method of exterminating harmful insects using digital dimming of an LED and a flexible printed circuit board are provided to increase a divergence angle coming out by using the flexible printed circuit board. CONSTITUTION: An LED light source part(10) includes a plurality of light emitting diodes serially connected. A dimming part(20) is composed of a transistor controlling optical power of the light emitting diode. The dimming part on/off-switches a plurality of light emitting diodes included in a dimming signal received from a control part(40). A constant current regulator(30) is composed of a DC-DC converter having an LED drive exclusive constant current IC or a current sensing resistor. The control part generates the dimming signal including a frequency which on/off switches the LED light source part. A power supply circuit(50) is composed a circuit which raises/drop an input voltage with an output voltage necessary for driving the light emitting diode. An input part(60) receives an input signal of a user. A storage(70) is a database including time when harmful insects are active.
