Adhesive-type insect trap having a light source seat and a light source mount

An adhesive-type insect trap comprising:

• a main body having an adhesive sheet insertion hole;
• a light source mount disposed on the main body;
• a cover detachably attached to the main body and having a through-hole formed in at least a portion thereof,
• an adhesive sheet guided into the main body via the adhesive sheet insertion hole;
• a light source mounted on the light source mount;
• and
• a sensor operable to detect:
• at least one kind of insect trapped on the adhesive sheet,
• an area of the adhesive sheet trapping insects, brightness of the adhesive sheet,
• an ambient temperature of a light source,
• intensity of light emitted from the light source,
• ambient illuminance of the insect trap,
• a time for replacement of the adhesive sheet,
• insertion of the adhesive sheet into the insect trap, and
• attachment of the cover to the insect trap;
• wherein the sensor further comprises an illuminance sensor for detecting illuminance of ambient light around the adhesive-type insect trap;
• wherein:
• a drive voltage applied to the light source mounted on the light source mount is controlled through PWM (Pulse Width Modulation) depending upon variation in illuminance of ambient light;
• and
• the drive voltage applied to the light source has at least two duty ratios;
• a first duty ratio of the drive voltage applied to the light source is s % when the illuminance of ambient light detected by the illuminance sensor is less than a preset illuminance range;
• a second duty ratio of the drive voltage applied to the light source is b % when the illuminance of ambient light detected by the illuminance sensor exceeds the preset illuminance range;
• and
• the first and the second duty ratios of the drive voltage satisfy a relationship:
• b>s.
