摘要:
A glass mercury dispenser for inclusion within an arc discharge lamp is surrounded by a particle shield to catch shards when the capsule is subsequently ruptured.
摘要:
A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. There is a gap in the shield and a mercury-containing glass capsule disposed proximate the gap. The capsule is supported on the shield by means of an axial wire in the capsule extending beyond both ends of the capsule and welded to the shield. A crack in the glass permits the mercury in the capsule to develop a vapor pressure in the lamp.
摘要:
A compact flourescent lamp assembly includes a triple bend lamp and a first housing including a ballast and a screw-in base for use with an incandescent fixture. A second housing, attached to the lamp, includes a glow switch and starting capacitor. The triple bend lamp is fabricated from a previously completed elongate lamp.
摘要:
A compact energy-saving discharge lamp adapter with a take-apart feature for easy installation into incandescent lamp fixtures. The two-part adapter unit consists of a discharge lamp socket assembly and a ballast assembly. The discharge lamp socket assembly comprises three different electrical type connectors arranged in a special housing for lamp and ballast assembly attachment. The ballast assembly comprises a ballast, associated connectors, and special housing containing thermal conductive compound and mountable directly on the socket assembly.
摘要:
In a fluorescent lamp having a multi-layer phosphor, a halophosphate-containing layer having color coordinates within an oval centered on X=0.382 and Y=0.384. A rare earth activated phosphor layer has approximately the same color coordinates. The area density ratio of the rare earth and halophosphate-containing phosphor layers is between 0.088 to 0.222 and preferably between 0.088 to 0.133.
摘要:
A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. The shield has a narrow gap between its ends with a mercury containing metal capsule in the gap. The lower portion of the capsule is connected to the ends of the shield so that when an Rf current is induced in the shield, it preferentially flows through the lower portion of the capsule.
摘要:
A conductive link maintains the electrode of a fluorescent lamp and a conductive electrode guard at the same electrical potential to reduce lamp power dissipation. The conductive link is a bimetal strip arranged for electrically connecting an electrode lead-in with the electrode guard or electrode guard support upon heating by the discharge arc during lamp operation.
摘要:
A conductive link maintains the electrode of a fluorescent lamp and a conductive electrode guard at the same electrical potential to reduce lamp power dissipation. The conductive link may be a fuse wire to protect the lamp ballast from excessive current upon electrode failure and shorting to the electrode guard.
摘要:
A rapid start fluorescent lamp ballast with a secondary winding supplying lamp current and tertiary windings for supplying heater current, has a magnetic switch which senses current through the secondary winding and opens the heater current circuit after the lamp starts and draws operating current from the secondary winding. The current sensing magnetic switches shown are a slow acting relay with its coil in the secondary circuit and a magnetic reed switch physically disposed in the magnetic field of the secondary ballast winding.
摘要:
A rapid start fluorescent lamp contains a circuit opening device on the cathode mount which opens a short time after lamp starting and stops heater current flow to the cathode. The circuit opening device is a thermostatic element in a sealed glass tube. Additional support is provided for the cathode end that is connected to the circuit opening device in order to prevent damage from vibration.
