  • Patent number: 8564203
    Abstract: A discharge lamp unit has a supporting member supporting a discharge lamp, a circuit substrate supplying electric power to the discharge lamp, a housing case member, a separation wall, and a hollow part. The housing case member supports the circuit substrate in an inside space thereof and the supporting member. The supporting member is exposed to an outside of the housing case member. The separation wall separates the supporting member from the circuit substrate in the inside space of the housing case member. The hollow part is formed between the separation wall and the circuit substrate. When the supporting member is heated by heat energy of the discharge lamp, the separation wall shields the heat conduction from the supporting member to the circuit substrate. The presence of the hollow part between the separation wall and the circuit substrate prevents heat conduction from the discharge lamp side to the circuit substrate.

  • Publication number: 20120313521
    Abstract: The inventive concept is directed to a heat shield on a Compact Fluorescent Lamp CFL. When a CFL is installed in an upside down position, that is, the screw-in section is up and the lighted section is down, the heat created by the lighted section rises and impacts on the ballast section right above it. The ballast section may malfunction and may fail altogether. The heat shield is of a conical configuration and the smaller diameter end is slipped over the threaded section but will stop just above the wider diameter of the ballast section. This way, the heat cannot reach the ballast section to greatly prolong the life span of the CFL. On an upper section of the heat shield there are provided spring retainers which will provide a snug fit of the heat shield on the top of the ballast. The heat shield may be adjusted into somewhat different directions to enhance the direction of the light emanating from under the heat shield.

  • Patent number: 8314557
    Abstract: At an initial stage of a discharge start, a shield electrode is connected to a ground potential via a bidirectional voltage trigger switch. Thereafter, when an electrical charge within the shield electrode flows to the ground potential, by being triggered with this potential, both terminals of the bidirectional voltage trigger switch are disconnected therebetween. Thus, at an initial stage of discharge, charging of the shield electrode is suppressed to suppress a decline in discharge, and in a sustained discharge, destabilization due to an unwanted discharge from the shield electrode to the anode can be suppressed, and using such an electrode automatically allows improving the lighting performance of a discharge lamp.

The shatterproof silicone coated compact fluorescent lamp with containment system will prevent the bulb from shattering or exploding if dropped. The silicone overmold is adhered directly to the glass gas filled tube and base allowing for containment of mercury and as a catalyst for recycling. Methods of manufacturing silicone coated compact fluorescent lamps by dipping a bulb in a solvent dispersion of uncured silicone rubber to provide one or more layers is also provided.

  • Patent number: 8018129
    Abstract: An entire length of a fluorescent lamp is made short to allow the fluorescent lamp to be downsized and the part other than the fluorescent lamp to be shortened so as to advantageously improve the design potentials and enhance the lighting effect. A fluorescent lamp to be fitted to a feeding side member, or a hook ceiling, having a pair of retaining holes and a pair of feeding side terminals arranged at corresponding positions, comprises a fluorescent lamp main body, an inverter-containing case arranged at a proximal end side of the fluorescent lamp main body and a pair of terminals arranged at the side of the case opposite to the fluorescent lamp main body. The pair of terminals have the tip ends bent so as to be retained by the feeding side member and establish electric connection to the feeding side terminals as they are respectively inserted into the pair of retaining holes of the feeding side member and displaced in the rotating direction around the center of the fluorescent lamp.

  • Patent number: 8018130
    Abstract: The invention relates to a lamp system comprising a low-pressure mercury vapor discharge lamp having a discharge vessel (6) enclosing a discharge space (8), with two electrodes (10, 30) positioned in the discharge vessel and an amalgam (18) arranged at a first end section (28) outside the discharge path between the first electrode and the second electrode. A ballast generates an electrical discharge current independently of an electrical heating current. A heating element (22) is positioned in the first end section for heating the amalgam using the electrical heating current. The temperature of the amalgam can be kept within its optimal temperature range for a relatively broad range of operating conditions.

    Abstract: A sealing structure that hermetically seals an open end of an outer envelope to a lamp base of a compact fluorescent bulb to prevent release of mercury to the environment. The sealing structure may be a tightened band, snapped together structures or an adhesive. The outer envelope is resistant to tearing from shards of glass in the event of breakage of the bulb and resistant to heat given off by the bulb during illumination so as to maintain and integrity of the outer envelope throughout exposure to the heat. The sealing structure and outer envelope may be packaged together as a kit.

  • Patent number: 7857498
    Abstract: An electronic-ballast lamp system comprises a modular lamp ballast in a plug-in housing. A light fixture has matching sockets for the ballast and is pre-wired for the intended lamp tubes. In one instance, an electronic ballast accepts 100-300 VAC and 50-60 Hz power inputs, and provides the correct rapid-start, instant-on, or standard lamp outputs as sensed from the lamps themselves, or as read from a data card embedded in the light fixture. The data card is read optically or electronically, depending on application, or the lamp types may be dialed-in on the ballast itself.

  • Publication number: 20100308728
    Abstract: A discharge lamp unit constitutes circuit components including self-heating components that radiate the heat, i.e., a circuit board and a DC/DC transformer, and a heat radiation member. The heat radiation member made of metal is arranged in a portion between the self-heating components and the other components, so as to cover at least a portion of the heat radiation member. In the discharge lamp unit, the heat produced by the self-heating components can be absorbed by the heat radiation member before the conducting heat reaches the circuit components other than the self-heat components. As a result, the heat produced by the self-heating components can be effectively radiated away.

Such an end-to-end structure may be constructed for use inside a single protective sleeve, such as one constructed of transparent quartz in embodiments where the assembly is used in a decontamination reactor equipment. In exemplary embodiments, the lamps are securely coupled, or otherwise fastened or linked, together end-to-end using any appropriate means for ensuring the integrity and longevity of the connection between the ends of the lamps. The integrity of this end-to-end connection would prevail under any and all circumstances, such as shipping or otherwise moving the assembly, or under normal or abnormal operating conditions, or even in the event that any equipment in which the lamp assembly is used fails during its operation.

  • Publication number: 20100187996
    Abstract: A discharge lamp unit has a supporting member supporting a discharge lamp, a circuit substrate supplying electric power to the discharge lamp, a housing case member, a separation wall, and a hollow part. The housing case member supports the circuit substrate in an inside space thereof and the supporting member. The supporting member is exposed to an outside of the housing case member. The separation wall separates the supporting member from the circuit substrate in the inside space of the housing case member. The hollow part is formed between the separation wall and the circuit substrate. When the supporting member is heated by heat energy of the discharge lamp, the separation wall shields the heat conduction from the supporting member to the circuit substrate. The presence of the hollow part between the separation wall and the circuit substrate prevents heat conduction from the discharge lamp side to the circuit substrate.
