Claims (14)

1. A compact, well-heat-dissipating fluorescent lamp unit with a reflector, comprising a lamp cover, lamp, electronic ballast assembly connected to the lamp cover and lamp, circuit board, housing, and an intermediary plate enclosing the electronic ballast assembly and circuit board, a reflector cup, and a transparent sheet mounted on the open end of the reflector cup. A unique design is achieved where the electronic ballast assembly is mounted on the circuit board via fasteners, both of which are housed within the housing. Multiple slotted holes, each secured with hollow conductive rivets, are provided on the circuit board. Mounting holes are arranged on the top surface of the housing for mounting the lamp cover. An annular recess is arranged on the inner circumference wall at the bottom of the housing, and multiple snap-on assemblies are arranged on the inner circumference wall near the annular recess. The intermediary plate consists of an annular protrusion extending upwards from within the base plate and a base plate on its top surface with multiple electrical contacts corresponding to the slotted holes of the circuit board. On its lower surface, there are two minimum protrusions, and hollow protrusions positioned on one side of these two minimum protrusions are arranged. Multiple snap-on legs corresponding to the snap-on assembly of the housing are arranged from the perimeter edge of the base plate to the outside of the annular convex plate, with the electrical connection legs of the intermediate plate inserting into the slot holes of the circuit board. The snap-on legs are connected to the snap-on assembly of the housing, and the annular convex plate overlaps the annular recess of the housing, thus closely connecting and securing these components in a relative manner. The hollow reflector cup, in which the light bulb can be received, has several mounting holes corresponding to the two minimum protrusions of the intermediate plate on its top surface. Notches positioned on one side of the mounting holes are arranged, and the reflector cup is secured to the lower surface of the intermediate plate via a snap-on fit into the mounting holes and notches, as well as the hollow protrusions and extensions of the intermediate plate. 2. A fluorescent lamp unit with a reflector, as specified in Claim 1, where the number of holes for inserting the circuit board, the connecting pins of the intermediate plate, the snap-in assembly of the housing, and the snap-in legs of the intermediate plate are four, respectively. 3. A reflector fluorescent lamp unit as specified in Claim 1, where the housing is in the form of a stepped casing. 4. Reflector fluorescent lamp unit as described in Claim 3, where the housing includes two to five overlapping layers, where annular recesses are arranged on the lower minimum layer and multiple positioning fins are arranged on the walls along the inner perimeter of the upper minimum layer, matching the perimeter edge of the circuit board. 5. A reflector fluorescent unit as described in claim 4, whereby the housing shall include three overlapping stepped layers, the lowest of which is trumpet-shaped, on top of which two cylindrical layers are arranged, their diameters decreasing in steps from the lowest layer. 6. A fluorescent lamp unit with a reflector, as specified in Claim 1, where the housing is made of a plastic material. 7. A fluorescent lamp unit with a reflector, as described in Claim 1, where on the lower surface of the intermediate plate there are two axially symmetrical projections, while two axially symmetrical mounting holes corresponding to the two projections are arranged on the top surface of the reflector cup. 8. A fluorescent lamp unit with a reflector, as specified in Claim 1, where the reflector cup is made of metal, and its inner surface has a high degree of fineness from abrasion or chemical treatment, and its outer surface has a high degree of roughness from non-polishing. 9. Fluorescent lamp units with reflectors, as specified in claim 8, where the reflector cup is made of aluminum alloy. 10. A fluorescent lamp unit with a reflector, as described in Claim 1, where annular grooves are arranged at the bottom of the inner wall of the reflector cup, and circular raised plates paired with the annular grooves are arranged around the edge of the transparent sheet, causing the transparent sheet to be embedded in the annular grooves of the reflector cup, and the top edge of the reflector cup is firmly attached to the bottom of the housing. 11. A fluorescent lamp unit with a reflector, as described in claim 10, where the convex circular plate of the transparent sheet and the annular groove of the reflector cup overlap in a fixed manner, while the top edge of the reflector cup and the bottom of the housing are also firmly joined together by adhesive. 12. A fluorescent lamp unit with a reflector, as specified in Reputation 1, where the lamp cover is of the two-post or threaded type, which is mounted on the top surface of the housing or has a mounting hole on the top surface. 13. Reflector-equipped fluorescent units as specified in Claim 1, where the lamp is installed within a reflector cover and a compact fluorescent tube of type 2SL, 2WL or 4SL is available. 14. A fluorescent lamp unit with a reflector, as specified in claim 1, whereby the lamp can be snap-in into the hollow protrusions of the intermediate plate by inserting the lamp legs into its electrical connectors and securing them with adhesive.
