| 20110291585 | STEPPED DIMMING DEVICE FOR LED LAMP - The present invention relates to a novel dimming device for a LED lamp capable of effecting a stepped dimming of the LED lamp by detecting a momentary variation in on/off states of the power switch, enabling the LED lamp to vary to work in a plurality of working states in a cyclic manner according to a predetermined program. The dimming device the present invention overcomes the technical problems of using a regular power switch to effect dimming and allows the use of the regular power switch to effect the stepped dimming of LED lamp. The present invention may also use an external DC signal source to effect the stepped dimming of LED lamp. According to the present invention, a user may adjust the brightness of the LED lamp when needed, which not only facilitates the daily life of the user but also effectively save the energy. | 12-01-2011 |
| 20110134644 | REFLECTOR CUP AND LED LAMP COMPRISING THE SAME - 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. | 06-09-2011 |
| 20100182784 | LED reflector - An LED reflector lamp has a control circuit, at least two LED light sources controlled by the control circuit, at least two light source panels coupled to respective at least two LED light sources, and at least one heat-conducting plate thermally connected to the at last two light source panels. The LED lamp reflector has a reflective cup having a reflective inner surface, a reflective opening formed by an edge of the reflective inner surface, and a slot formed on a bottom of the reflective cup, wherein the at least one heat-conductive plate is inserted through the slot into an interior of the reflective cup such that the LED light sources are parallel to a centrally vertical axis of the reflective cup. A heat sink is described that has a cavity in its interior, the cavity being dimensioned and shaped to be coupled to the reflective cup and plate. | 07-22-2010 |
