This present invention relates to an all-rounded illumination enveloped
fluorescent lamp. The light translucent materials used for lamp carrier disk fixing lamp tube, segregation board segregating wires,
ballast circuit board and rear housing enables light emitted by the lamp tube to penetrate through the rear housing via the lamp carrier disk, segregation board and circuit board, thus causing the whole lamp body to illuminate as the lamp is turned on. Furthermore, the rear housing, which is made of PC plastic with proper amount of colour
powder added, provides good
light transmission property but is not transparent, thus shielding the
ballast so that the appearance of lamp is beautiful. No
darkness zone is formed when in use. The lamp thus provides an advantageous aesthetic quality and illumination effect. The
light transmission amount of the rear housing is increased further by setting the circuit board perpendicularly to the lamp carrier disk or by adjusting the circuit board to be smaller than the bottom projection of lamp tube. The combination of a compact lamp tube and
ballast made by
surface mount technology with small dimension components and surface
mount components allows the inner space to be used fully and reduces the length and
diameter of the whole lamp efficiently by mounting part of the components into the inner space of the lamp base.
