Abstract
Disclosed herein is an adapter device for enabling the use of a compact fluorescent lamp in a lighting apparatus having a socket for an incandescent lamp. The adapter device includes a fastening structure, a cap, green and red Light Emitting Diodes (LEDs), and a Direct Current (DC) power supply. The fastening structure fastens the compact fluorescent lamp. The cap supplies Alternating Current (AC) power to the fastening structure. The green LEDs emit light in a wavelength range of 498-530 nm, and the red LEDs emit light in a wavelength range of 620-700 nm. The LEDs are installed around the compact fluorescent lamp. The Direct Current (DC) power supply supplies DC power to the green LEDs and the red LEDs.
