Adhesive-type insect trap having a light source seat and a light source mount
An adhesive-type insect trap includes a body having a hole for insertion of an adhesive sheet; a light source mounting unit disposed on the body; and a cover which is detachably mounted on the body and has a through-hole in at least a part thereof. The body further includes a light source seating unit provided so as to correspond to the light source mounting unit, and a light source may have one side thereof mounted on the light source mounting unit and the other side thereof seated on the light source seating unit.
1. 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.
2. The adhesive-type insect trap according to claim 1 , wherein the main body further comprises a side portion connected to at least a portion of the light source mount and the side portion is further provided with a display unit.
3. The adhesive-type insect trap according to claim 1 , wherein the sensor further comprises a UV sensor measuring the intensity of light emitted from the light source; and
wherein the light source mounted on the light source mount further comprises a light emitting diode and the UV sensor measures intensity of light emitted from the light emitting diode.
4. The adhesive-type insect trap according to claim 3 , wherein, when the intensity of light emitted from the light emitting diode and measured by the UV sensor is less than a preset value, the adhesive-type insect trap generates a light source replacement signal.
5. The adhesive-type insect trap according to claim 1 , wherein the light source comprises a plurality of light emitting diodes, the plurality of light emitting diodes being controlled to be sequentially turned on/off.
6. The adhesive-type insect trap according to claim 1 , wherein the illuminance sensor comprises at least three preset illuminance ranges and the drive voltage applied to the light source is controlled to have a duty ratio changed depending upon variation in illuminance range.
7. The adhesive-type insect trap according to claim 1 , wherein the light source further comprises a support member and a light emitting diode disposed on the support member, and the sensor further comprises a UV sensor provided to the support member to measure the intensity of light emitted from the light source.
