PURPOSE: An LED fluorescent lamp with a light transmitting window of a diffusion film type is provided to improve harmlessness to a human body and the reliability and quality of a product by uniformly emitting light to the outside through a light transmitting window of a diffusion film type at a predetermined angle. CONSTITUTION: A heat radiation and LED board fixing hole(1) maintains a basic form of a fluorescent lamp, radiates heat, and fixes an LED substrate. An LED substrate mounting plate(11) is installed on a ceiling surface. A heat radiation and LED board fixing hole(3) reduces a weight and a size thereof by being shaped with magnesium. The heat radiation and LED board fixing hole serves as a light reflecting shade which reflects some light from an LED(21) to a light transmitting window of a diffusion film type. A screw(6) is fixed to the ceiling surface of an LED substrate mounting plate(11) of the heat radiation and LED board fixing hole through a thermally conductive adhesive or a double sided tape of a heat resisting type. |
