  • Publication number: 20140063813
    Abstract: A projection lamp includes a bulb, a main reflective cover and a secondary reflective cover. The bulb includes a wick and a lamp tube which wraps the wick. The wick is configured to emit divergent light beams while the bulb is lit up. The main reflective cover is connected to the lamp tube and includes a main reflective surface facing the wick. The main reflective surface is configured to convert the divergent light beams into projection beams. The secondary reflective cover is melt bonded to the lamp tube and includes a secondary reflective surface facing both of the wick and the main reflective surface. The secondary reflective surface is configured to reflect a portion of the divergent light beams, cannot be directly emitted onto the main reflective surface, onto the main reflective surface while the bulb is lit up.

  • Publication number: 20110291556
    Abstract: A gas discharge lamp includes a lamp tube, two electrodes and an electron emitter. The lamp tube has a hermetic discharge chamber filled with a rare gas and two sealing neck portions. Each of the sealing neck portions has a metallic foil disposed therein. Each of the two electrodes includes an emitting part and a connecting part. The connecting part is connected to a metallic wire via the metallic foil. The metallic wire extends out of the sealing neck portion to form a circuit contact. The electron emitter is made of a conductive material and electrically connected to one of the electrodes. A portion of the electron emitter disposed in the hermetic discharge chamber, and a diameter of an end of the electron emitter in the hermetic discharge chamber is less than an outer diameter of the connecting part.

  • Publication number: 20110121710
    Abstract: A lamp includes a tube, a first inner electrode and a second inner electrode. The tube has a cavity, a first sealed portion and a second sealed portion. The cavity is located between the first and the second sealed portions. The first and the second inner electrodes are disposed at the first and the second sealed portions respectively and extend into the cavity. The first inner electrode has a first rod and a first head portion disposed at a first end of the first rod and located within the cavity. A volume of the first head portion is between 1.0 and 30 mm3. The second inner electrode has a second rod and a second head portion disposed at a second end of the second rod and located within the cavity. A volume of the second head portion is between 0.1 and 4.0 mm3.

  • Patent number: 7893618
    Abstract: The gas discharge lamp contains a lamp body and an UV unit. The UV unit contains a separate airtight chamber wrapping around at least a neck member of the lamp body and covering at least a part of a Mo tinsel inside the neck member. The airtight chamber is filled with one or more gases capable of being ionized, and is wound by a conductor whose one end is connected to a conduction wire extended out of one of the neck members. When the gas discharge lamp is turned on, the gases in the airtight chamber are ionized to produce an UV light to penetrate the discharge chamber. The gas discharge lamp therefore could have a lower starting voltage and an improved starting efficiency. Additionally, as the airtight chamber provides a heat insulation effect, the temperature-induced stress is thereby reduced.

  • Publication number: 20100311279
    Abstract: An illuminating module includes an illuminating device and an electrical connector. The illuminating device includes a first conductive contact and a second conductive contact. The electrical connector includes an external plug, a first internal conductive terminal and a second internal conductive terminal. The first internal conductive terminal electrically connects the external plug and the first conductive contact. The second internal conductive terminal electrically connects the external plug and the second conductive contact. The connection manner of the first internal conductive terminal and the first conductive contact belongs to fool-proof connection. The connection manner of the second internal conductive terminal and the second conductive contact belongs to fool-proof connection.

  • Publication number: 20100007281
    Abstract: The present invention lights a gas discharge lamp with a stable average frequency and in the mean time grows tips evenly on the two electrodes of the gas discharge lamp so that the distance between the electrodes is maintained and the stability of the electric arc is enhanced. The present invention first applies a DC voltage and then a high-frequency AC voltage to the electrodes of the gas discharge lamp. The present invention then applies a reversed DC voltage and then a high-frequency AC voltage to the electrodes. This process is repeated and, as the tungsten ions in the electric arc are steadily deposited on the arc spots of the electrodes alternately and two tips are thereby evenly developed on the first and second electrodes, respectively.

  • Patent number: 7355346
    Abstract: The lighting device contains a quartz tube and a UV production member. In addition to a main chamber for high intensity discharge, the quartz tube has an auxiliary chamber formed around the conductor in a first end section. The UV production member contains a probe and a coil surrounding the first end section. An end of the coil is connected to a conducting wire from the other end section of the quartz tube. The other end of the coil is connected to the probe whose tip penetrates through the first end section of the quartz tube into the auxiliary chamber and points to the main chamber. When a voltage is applied, electrons are shot from the tip of the probe into the gas in the auxiliary chamber, and UV light is thereby produced and directed into the main chamber for the enhanced activation of the lighting device.
