CN2254261Y - Glow starter for fluorescent lamp - Google Patents

Abstract

The utility model relates to a glow starter for a fluorescent lamp. Double metal sheets in the casing of the utility model are connected with a resistance wire, a capacitor and a fuse. When electricity is supplied, the argon gas and the mercury in the whole fluorescent lamp are excited under the simultaneous function of the capacitor and a rectifier, and thereby, the whole fluorescent lamp emits light. The utility model overcomes the disadvantages that the existing glow starting is difficult under a low voltage, and both ends of the fluorescent lamp are easy to blacken. The resistance wire can switch off the double metal sheets after the fluorescent lamp is started, and the fuse is used for protection when the capacitor discharges. When both ends of the fluorescent lamp of which the filament is broken are sheathed with small iron sheets, the utility model can be used for refreshing the fluorescent lamp.

Description

Starter for fluorescent

The utility model relates to a kind of fluorescent lamp starter, is the improvement to existing general starter for fluorescent.

Existing general starter for fluorescent, general get electric expanded by heating and be in contact with one another by two temperature-sensitive contacts, dead electricity is cooled off and is decontroled mutually, reach to the filament pre-heating of fluorescent lamp and make the ballast coil instantaneous pressure of inducting, impel the discharge earlier of fluorescent lamp two ends and light, this starter is starter difficulty, difficult startup when voltage is low not only, and the easy blackening of lamp tube ends, and filament easily burns and causes lamp tube service life to shorten.

The purpose of this utility model provide a kind ofly start easily, the life-span is long, and can make the fluorescent lamp starter of useless Guan Fuxin.

The utility model is realized by following technical proposal:

The utility model is by shell, bimetal leaf, resistance wire, electric capacity, fuse is formed, resistance wire and electric capacity, fuse series connection back links to each other with bimetal leaf, and be enclosed in the shell, when energized, electric current is by ballast process bimetal leaf, electric capacity, resistance wire, the bimetal leaf expanded by heating outwards stretches and connects, argon gas is free in the electric capacity charging this moment fluorescent tube, the mercury vaporization, and electric capacity begins discharge at once again, just in a flash at this, the ballast two ends have produced very big induced potential, and fluorescent tube two voltage increases severely, and a large amount of electronics flow through from pipe, electronics produces electric arc at the volley, gas in the impact tube sends ultraviolet ray, thus the fluorescent material in the percussion pipe, fluorescent tube is at once just bright, at this moment, the bimetal leaf contact joins, and stops discharge, bimetal leaf cools off gradually, again disconnect,, can not discharge again because bimetal leaf two voltage across poles are lower, kept released state, thereby starter has stopped work.The effect of the utility model resistance wire is after lamp luminescence, can impel bimetal leaf to disconnect at once, and fuse plays the effect of protection fluorescent tube when capacitor discharge.

Under the situation that filament of fluorescent lamp burns, put small iron plate at disintegration of filament end earlier, filament two utmost points are connected, thereby made electric current can successfully lead to the starter place.

The utility model impacts the interior argon gas of fluorescent tube because effect electric capacity and ballast the time produces powerful induced potential and is added in lamp tube ends, thus fluorescent tube can be under the low situation of voltage rapid build-up of luminance; After mixing this device, be not that the lamp tube ends filament is earlier luminous during build-up of luminance, but whole fluorescent tube is simultaneously luminous, so lamp tube ends can blackening, filament also is difficult for burning; As long as the fluorescent tube of the disintegration of filament puts small iron plate and re-uses this starter, fluorescent tube can be answered newly, and lamp tube service life is strengthened greatly; This starter is only had an effect when build-up of luminance, and not perishable, the life-span is long.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model user mode reference diagram.

Accompanying drawing 3 is the reference diagram of the fluorescent tube of filament breaking when using the utility model.

Accompanying drawing 4 is the small iron plate structural representation.

As shown in Figure 1, this utility model has shell (1), and bimetal leaf (2), resistance wire (3), electric capacity (4), fuse (5) are arranged in shell (1), and resistance wire (3) links to each other with bimetal leaf (2) with electric capacity (4), fuse (5) series connection back.

As shown in Figure 2, the utility model is with existing general starter is the same is connected in the circuit.

As shown in Figure 3, when connecting the fluorescent tube (6) of the disintegration of filament, put small iron plate (7) blowing end, again the utility model is connected in the circuit, can make multiple new use of fluorescent lamp (5) of the disintegration of filament, the shape of small iron plate (7) as shown in Figure 4, its two ends have aperture (8).

Claims (2)

1, a kind of starter for fluorescent, comprise shell (1), bimetal leaf (2), it is characterized in that: resistance wire (3), electric capacity (4), fuse (5) series connection back link to each other with bimetal leaf (2), and resistance wire (3), electric capacity (4), fuse (5), bimetal leaf (2) all are enclosed in the shell (1).

2, according to claims 1 described starter for fluorescent, it is characterized in that: starter and filament breaking fluorescent tube (6) be when linking to each other, the small iron plate (7) of tube filament fracture end cover one (8) with holes.
