Abstract

A cold cathode fluorescent lamp lighting device includes a lens cover, a cold cathode fluorescent lamp and a control box. The lens cover is a semicircular-shaped tube and includes a post having a threaded hole for insertion of a bolt. The cold cathode fluorescent lamp is circular and secured in the lens cover. The control box includes a control circuit to control the lighting of the cold cathode fluorescent lamp. The control box further comprises electric wires and a connector to be connected with a connector of the cold cathode fluorescent lamp.

Claims

1. A cold cathode fluorescent lamp lighting device comprising;

a vehicle light;

an annular lens cover having a semicircularly-shaped recess, said annular lens cover being disposed on said vehicle light to circumscribe a perimeter thereof;

a substantially circular cold cathode fluorescent lamp, said cold cathode fluorescent lamp being secured within said recess of said lens cover and in contiguous contact with an inner wall of said lens cover; and

a control box electrically connected to said cold cathode fluorescent lamp, said control box including a control circuit to control the lighting of said cold cathode fluorescent lamp.

2. The cold cathode fluorescent lamp lighting device, as recited in claim 1, wherein said lens cover comprises a post having a threaded hole for insertion of a bolt to secure said lens cover to said vehicle light.
