RADIATION STRUCTURE AND USING THE SAME STRAIGHT TUBE TYPE LED FLUORESCENT LAMP

摘要

A radiation structure is disclosed. The radiation structure is configured to comprise: an LED mounting unit on which an LED module is mounted; and a heat radiation unit for radiating heat caused by heat generation of the LED module. The LED mounting unit is formed in a plate shape based on the cross-section of the radiation structure and the heat radiation unit is configured to include a hemisphere forming unit disposed on the LED mounting unit and heat radiating fins protruded from the surface of the hemisphere forming unit. The LED mounting unit and the hemisphere forming unit are connected to each other through a first extension portion which is extended toward the rear surface of the hemisphere forming unit from both sides of the LED mounting unit. A second extension portion is formed on the both sides of the LED mounting unit and extended in a direction away from the LED mounting unit from the first extension portion. A coupling groove is formed between the hemisphere forming unit and the second extension portion in order to combine a diffusing lens portion for diffusing light emitted from the LED module.
