One starting characteristics test circuit is arranged: above-mentioned selector switch SA ₂Start end pass through SA ₂Connect pressure regulator T, at the two ends of T and be connected to the startup pilot lamp loop, the pressure regulation end of pressure regulator connects a voltage table PV;

One switch test circuit is arranged: above-mentioned selector switch SA ₁Switch terminals one tunnel meet counter PC, another road is through selector switch SA ₃Meet time relay KT ₁, KT ₂With AC relay KA;

One panel is arranged: with the counter PC in the hookup, time relay KT ₁, KT ₂, voltage table PV, light emitting diode V ₂Back and all switches are arranged on the panel.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further details.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is a panel layout of the present utility model.

FU is that fuse, S are that switch, SA1, SA2, SA3 are selector switch, SB1 among the figure ... SB20 is keyswitch, SB1 ' ... SB20 ' is keyswitch, XT1 ... XT7 is that terminal connections row, DZ are that electric ballast, HT are that fluorescent light, SB21, SB22 are that pushbutton switch, V1, V2 are diode, V3 ... V23 is fluorescence lamp starter, L1 ... L20 is an Inductive ballast.

Circuit connecting relation of the present utility model as described above.Now its principle of work is summarized as follows in conjunction with Fig. 1:

After switch S was connected, one road electric current was through R ₁Form the loop with H lamp (H) is lighted, devices illustrated is in running order.Another road is through S, SA ₂, SA ₁, SB ₁, SB ₁, L ₁Filament (on), V3 and filament (descending), get back to center line (N), lamp (HT) is triggered lights (inductance startups), when work as the need electric start, a need is with change-over switch SB ₁', press and get final product, vice versa.This just can carry out the test in the aging or life-span of lamp.

Starting characteristics test: earlier with switch S A ₂And SA ₃Pull out respectively to starting state, this moment, voltage was through SA ₂And SA ₃Add to the input end of pressure regulator T.Electric current passes through V simultaneously ₁, R ₂And V ₂Form the loop and make startup pilot lamp (V ₂) light, illustrate to be in the starting characteristics test state.

Output voltage is through SA ₂, SB ₁, SB ₁', filament (on), V ₃Filament (descending) forms the loop.When pressure regulator boosted, voltage was directly read by voltage table PV, and when voltage rose to certain value, lamp started light, and the reading of writing down voltage table this moment is the trigger voltage of this lamp.

Switch test: earlier with SA ₂And SA ₃Pull out respectively to the normality position, again switch S A ₁Pull out to the position of the switch.One the tunnel through S and SA ₁Enter PC (counter), make its work as the operating voltage of PC.Another route S, SA ₁And SA ₃KT simultaneously flows through ₁And K _A, make its work.Because K ₄Adhesive, its movable contact KA ₁The adhesive conducting is so electric current is by S, SA ₂, SA ₁, SB ₁, L ₁Filament (on), V ₃And filament (descending) formation loop starts light lamp (HT).With this simultaneously, when the KA adhesive (when lamp is bright), time relay KT ₁When also beginning time that the work of clocking (time-delay) presets when delaying time to, KT ₁Action is with K _ACut off (KA ₁Disconnect), this moment, lamp went out.While KT ₁Action also make KT ₂KT is worked as in the work of clocking ₂Just action makes KT when delaying time to preheating setting time ₁Outage because KT, outage, KA adhesive once more (bright lamp), this just can regulate the setting delay time respectively by predefined open and close time length, makes it to carry out again and again the switch test of fluorescent light.

Counting: switch test must be counted, and the very simple (see figure 1) of principle is worked as the every adhesive of KA once (lamp is once bright), the movable contact KA of KA ₂Also the adhesive conducting once forms a pulse and inputs to the PC counting once, so just can add up the switch number of times of lamp.

SB ₂₁And SB ₂₂Be under the switch test state, the Pause key in the no time limit of timing relay and return-to-zero key.

The utility model is with the counter PC in the hookup, time relay KT ₁, KT ₂, voltage table PV, light emitting diode V ₂, fuse FU and all switches be arranged on the panel.Operation is very easy, intuitive display.The panel plane design arrangement is seen Fig. 2, in finite size 600～700 (length) * 300～400 (wide).

This product is compared with the employed similar testing equipment of present electric light source industry, and following advantage is arranged:

1, combination property is strong, a tractor serves several purposes,

2, easy to operate, the efficient height,

3, counting is provided with memory function (numeral is not affected after namely having a power failure),

4, volume is little, cost is low and open, and the pass time can be set arbitrarily at 0.01S～100h.

, reliably, can connect for a long time work 5, safely.

With the counter PC in the hookup, time relay KT₁、KT ₂, voltmeter PV, light emitting diode V₂Rear and all switches are arranged on the panel.
