HEAT DISSIPATION MEMBER HAVING VARIABLE HEAT DISSIPATION PATHS, AND LED LIGHTING ILLUMINATION LAMP USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To maximize heat dissipation effect, prevent a scald due to contact with a high-temperature heat dissipation plate, and prevent a reduction in heat dissipation efficiency caused by foreign substances. PSOLUTION: The LED lighting illumination lamp that employs a heat dissipation member having variable heat dissipation paths includes: LEDs; an LED mounting substrate on which the LEDs are mounted; a heat dissipation member having a lower part to which the LED mounting substrate is fixed and provided with the variable heat dissipation paths formed thereon; an upper cap fixed to outer surfaces of heat dissipation plates of the heat dissipation member; a fixing ring member fixed to the lower part of the heat dissipation member to achieve inflow of outside air; and a lower lens fixed to a lower part of the ring.
