Abstract

The utility model relates to a distributor for a fluorescent lamp. The utility model is composed of a capacitor C, an inductor L1, and an inductor L2. In the utility model, the capacitor C is connected in series with the inductor L1 and then is in tandem connection with one input end of the fluorescent lamp; the inductor L2 is connected in parallel with both ends of the fluorescent lamp. The utility model with capacitive load has the advantages that power factors are increased for electric networks, energy is saved, start can be carried out under low voltage (140V-150V), starting current is weak, and firing speed is high. For a lamp tube which is matched with the utility model, light stream has sufficient light, phenomena of two black heads do not occur, and beautiful appearance and durability can be obtained. The utility model is suitable for being matched with fluorescent lamps of different power.

Description

CLL fluorescent lamp distributor

The utility model relates to a kind of fluorescent lamp distributor.

The distributor of existing fluorescent lamp generally is made up of ballast and starter, and it has characteristics such as simple in structure, but its build-up of luminance speed is slow, and the variable shadow in fluorescent tube two ends is rung attractive in appearance and useful life.The distributor of charged sub-starter, though build-up of luminance speed is fast, noise is big during build-up of luminance.

The purpose of this utility model is to overcome the weak point of existing fluorescent lamp distributor, designs a kind of fluorescent lamp distributor that is capacitive load.

The utility model is by capacitor C, inductance L ₁And inductance L ₂Form capacitor C and inductance L ₁Be serially connected with an input of fluorescent lamp behind the polyphone, inductance L ₂Be connected to the two ends of fluorescent lamp.

Design principle of the present utility model is adapted to the fluorescent tube of different capacity, and just its manufacture method is different: generally speaking, and L ₁And L ₂Can make respectively; When the power of fluorescent lamp pipe is big, can be L ₁And L ₂Be wound on the same iron core, form a special transformer; When the power of fluorescent lamp hour, available resistance R replaces inductance L ₁,, then form CRL fluorescent lamp distributor by capacitor C resistance R current limliting.

The utility model has following characteristics:

1, this fluorescent lamp distributor is a capacitive load, and the household appliance major part of using now is an inductive load, and capacitive load and inductive load complementation can obviously reduce the voltage landing between circuit, increase substantially the power factor of electrical network.

2, power consumption, cost are than reducing more than 1/3rd with power inductance ballasts.

3, (140～150V) all can start work to low-temp low-pressure.

4, the fluorescent tube that matches, starting current is little, and switch one closes, and fluorescent tube is a light flow foot, does not have the black phenomenon in two, and is attractive in appearance durable again.

Following embodiment is further described operation principle of the present utility model and manufacture method in conjunction with the accompanying drawings:

Fig. 1 is the utility model electrical schematic diagram (winding diagram).

Fig. 2 is the outside drawing of present embodiment.

With reference to Fig. 1, after the energized, CL ₁L ₂Serial resonant has the electric current of nearly 0.4A to make filament heating, L in the circuit during resonance ₂Two ends have the alternating voltage of nearly 300V to impel the rapid conducting of fluorescent tube, and both end voltage is reduced to about 50V after the fluorescent tube conducting, L ₂No current passes through again, by CL ₁Be fluorescent tube current-limiting.

Selection of components and making: capacitor C can be selected the electric capacity of the dacron of withstand voltage 2S0V for use, and capacitance is 4.5 μ F; Inductance L ₁Be washed into 13 * 16mm with general silicon steel sheet, compose thick 1lmm, the skeleton macaroni is 11 * 16mm, high 13mm, and the high strength enamelled wire with normal line footpath Φ 0.26mm tightens around 430 circles at its skeleton again; Inductance L ₂Iron core can be with the oblique E font silicon steel sheet in the fluorescent lamp ballast, its core area is 14 * 22mm, two be a day font, folded thick 1lmm, the high strength enamelled wire with Φ 0.125mm on its skeleton encloses around 3000.

Assembling: because of inductance L ₁It is very little to generate heat during work, can be capacitor C and inductance L ₁, L ₂With being fitted together, external packing is docile and obedient preface CL with the thick iron sheet of 0.1mm ₂L ₁The totally-enclosed cuboid that is packaged into 34 * 27 * 70mm, each connection place viscose glue, outer lead-out wire are a, b, e, d, as shown in Figure 2.

Claims

1, a kind of fluorescent lamp distributor is characterized by: by capacitor C, inductance L ₁And inductance L ₂Form capacitor C and inductance L ₁Be serially connected with an input of fluorescent lamp behind the polyphone, inductance L ₂Be connected to the two ends of fluorescent lamp.

2, according to the described fluorescent lamp distributor of claim 1, it is characterized by: described inductance L ₁And inductance L ₂Be wound on the same iron core.
