Abstract: The present invention provides a reflector cup for a lamp, including a cup body, a cup top having an aperture through which a light source is inserted into the reflector cup, and a cup bottom provided with an opening for outputting lights from the light source. The cup body is provided with a plurality of recesses or protrusions that have a curvature different from that of a surface profile of the reflector cup. In one preferred embodiment, the cup body is provided with a plurality of grid veins arranged in a matrix, in each of the grid veins is formed a protruded or recessed curved surface. The curved surface may be spherical, cylindrical, conical or the like. The invention also provides a LED reflector lamp comprising the reflector cup.

Abstract: A compact reflector fluorescent lamp unit includes a lamp cap, a lamp tube, an electronic ballast assembly, a circuit board, a housing, an intermediate plate, a reflection cup, and a transparent plate. The intermediate plate and the housing, the intermediate plate and the circuit board, and the intermediate plate and the reflection cup are tightly assembled together. The reflection cup is connected to a lower surface of the intermediate plate and arranged independently underneath the housing, and has an internal surface having a high degree of fineness, and an external surface having a high degree of roughness by frosted finishing, thereby allowing the radiation heat generated through the body of the reflection cup to be dissipated by the external surface.

Abstract: A split fluorescent lamp comprising a lamp body having a pluggable lamp cap and a lamp base with which the pluggable lamp cap is engaged, characterized in that an electronic ballast is embedded in the pluggable lamp cap, wherein the overall dimension of the lamp body and lamp base being assembled together is substantially equivalent to that of a G23 or G24 type plug-in fluorescent lamp such that it can be used to replace the plug-in fluorescent lamp of prior art adopted in a light fixture without changing the original design and power supply thereof.

Abstract: A fluorescent lamp adapted for effecting stepless dimming with a regular SCR dimmer, comprising a filter and rectifier circuit (1), a DC high voltage stabilizing circuit (2), a voltage signal detection and frequency control circuit (6), a lamp load (4), a lamp current feedback circuit (5) and a voltage signal sampling circuit (3) thereby changing the power factor and luminous intensity of the lamp in accordance with the variation of the conduction phase angle of the silicon controlled rectifier dimmer. The present invention solves the discontinuity and instability issues in course of dimming operation and is particularly adapted for use in an integrated compact fluorescent lamp.
