Abstract
The utility model relates to a long life fluorescent lamp with no filaments, which uses ordinary metal wires to replace fluorescent lamp tubes. The long life fluorescent lamp with no filaments is in particular suitable for lighting in trains, automobiles and production shops with larger vibration, except that the long life fluorescent lamp with no filaments is suitable for families, schools, organs and hotels. Using the ordinary metal wires as the filaments of the fluorescent lamp can save a plurality of noble metals for country, and the production technology is also simplified. The utility model has the advantages of low cost, long service life and energy saving.
Description
The utility model belongs to a kind of light fixture.
The object of the present invention is to provide a kind of novel long-lived fluorescent lamp.Fluorescent tube is to do light emitting source with tungsten filament in existing technology, but that tungsten filament is lighted the life-span is also shorter, and it is disconnected easily to be subjected to vibrating filament, and ballast itself also will consume a part of electric energy.
In order to overcome above-mentioned shortcoming, the present invention has cancelled the filament in the fluorescent tube, has adopted the common metal silk to replace tungsten filament.Can be country like this and save a large amount of precious metals, make the fluorescent tube simplified manufacturing process, about cost decline 20-30%, the fluorescent tube of comparable present use improves useful life more than five times, improve about 20-40% than same wattage lamp tube power factor, economize on electricity 15-30%, every technical indicator is all very desirable.
Embodiment:
The structure of long-life fluorescent tube is as shown in Figure 1: 1. fluorescent tube, 2. phosphor powder layer, 3.4. permanent joint, 5.6. insulating trip, 7.8. wire.Its operation principle is as shown in Figure 2: 3,4 ends that the two ends wire 7,8 of fluorescent tube 1 inserted chargers, 1,2 terminations of charger are gone into the 220V power supply, the electron stream that charger produces enters lamp tube ends wire 7,8 ends, electron stream enters in the fluorescent tube by the principle of wire point discharge, gets on the fluorescent material and emits light.
In the accompanying drawing 1: 1. fluorescent tube, 2. phosphor powder layer, 3.4. permanent joint, 5.6. insulating trip, 7.8. common metal silk.
In the accompanying drawing 2: 1.2. power supply, 3.4. charger terminals, 7.8. fluorescent tube wire.
Claims (3)
1, a kind ofly replaces tungsten filament to do the Durable fluorescent lamp tube of daylight filament, it is characterized in that not re-using the filament of precious metal tungsten filament as fluorescent lamp by the common metal silk.
2, the principle according to the two ends wire point discharge of claims 1 described Durable fluorescent lamp tube enters in the fluorescent tube, gets on the fluorescent material and sends light.
3, be by the supporting use of the charger of special use according to the described Durable fluorescent lamp tube of claims 1.2..
