A compact reflector fluorescent lamp unit with good heat dispersion, comprising a lamp cap, a lamp tube, an electronic ballast assembly, a circuit board, a housing and an intermediate plate, a reflection cup, and a transparent plate, wherein th e intermediate plate and the housing, the intermediate plate and the circuit board, and the intermediate plate and the reflection cup are respectively tightly assembled together by a snap-fit or coupling mechanism. Further, the reflection cup is connected to the lower surface of the intermediate plate and arranged independently at underside of the housing, and it is made of a material of aluminum alloy; wherein its internal surface has a high degree of fineness by means of polishing or chemical treatment to facilitate the reflection of light, and its external surface has a high degr ee of roughness by means of frosted finishing thereby allowing the radiation heat generated by the lamp tube in operation to be effectively conducted through the body of the reflection cup to the rough and enlarged external surface such that the heat can be sufficiently dissipated by the reflection cup. Therefore, the present invention possesses the features of high in reflective light efficiency, good in heat dispersion, fa st in heat conduction, small in volume, and compact in structure.
