CN2162756Y - Low voltage starter for fluorescent lamp - Google Patents

Abstract

The utility model relates to a low voltage starter for a daylight lamp, which is formed by that a high-power diode is connected with the existing starter in series. The high-power diode can be installed in a metallic case, also installed at the outside and an external case is added. The utility model can cause the daylight lamp to instantly start in the lower voltage of an electric network, can avoid shortening the life time of a lamp tube because of a repeat glow starting and can save power. The utility model has the advantages of simple structure and low cost, and a user only needs to install the starter on the original plug socket of the daylight lamp without modifying an original daylight lamp.

Description

Low voltage starter for fluorescent lamp

The utility model relates to the improvement of the igniter of discharge lamp, particularly common starter for fluorescent.

Starter for fluorescent at present commonly used is neon tube in parallel and an electric capacity between 2 electrodes, and it often can not make fluorescent lamp light when lower or temperature is low at voltage, starts repeatedly through starter sometimes fluorescent lamp is lighted.Often starting the life-span will inevitably shorten fluorescent tube and starter repeatedly also can cause waste of electric energy.Be No. 87212609, state's patent, " electronic starter for fluorescent lamp " by name, it is made of 8-12 components and parts, can make the rapid build-up of luminance of fluorescent lamp when line voltage is low.But this starter needs 8-12 components and parts have been assembled and have been loaded on the specific housing or support, and cost increases more than 2 times than existing starter; Original starter and base thereof to be removed in use, connect this starter again, make the renewal starter convenient inadequately.The CN87208883 patent, " the automatic starter switch of fluorescent lamp " by name adopts a specific slide switch form, and starter and mains switch is integrated, can start fluorescent lamp fast.It exists cost higher and problem such as must the existing fluorescent lamp of repacking when using this device make things convenient for inadequately too.

The purpose of this utility model be to provide a kind of can be when low pressure the fluorescent lamp low-voltage starter device of Fast starting, this starter is made of few several electronic components, being easy to manufacturing, cheap user only needs former starter is taken off, changing this starter can use, and need not to reequip original fluorescent lamp, bring convenience to the user.

This fluorescent lamp low-voltage starter device is achieved in that the high power semi-conductor diode of connecting between arbitrary electrode of existing starter and neon tube, electric capacity, this diode can be loaded within the starter metal shell, also can be loaded on outside it, can establish shell body in addition in the time of outside being loaded on metal shell.

This fluorescent lamp low-voltage starter device is because of being in series with heavy-duty diode, this diode and ballast form the equivalent electric circuit of tunnel diode when line voltage is low, although the voltage on fluorescent tube under the effect of tunnel effect is not high, but near electrode, form very strong space charge layer in the certain limit, just can cause extremely strong electric field in this zone, cause field emission, make the fluorescent tube conducting.When this starter can guarantee that voltage 170V is above, the rapid starter of fluorescent tube.The user need only take off original starter, and this starter of packing into can use, and need not original fluorescent lamp be reequiped, and brings convenience to the user.This starter is simple in structure, and the manufacturing cost that is easy to go into operation is more cheaper than aforementioned binomial patented product.

Be described further below in conjunction with accompanying drawing

Fig. 1 is the structural representation of fluorescent lamp low-voltage starter device

Fig. 2 is the configuration diagram of 160V low-voltage starter device

Fig. 3 is the electrical schematic diagram of this starter

In the cut-away view of Fig. 1, can see the structure of this low-voltage starter device, also be one of embodiment of the present utility model, in the time of outside heavy-duty diode 4 is loaded on starter metal shell 2, diode one end and arbitrary electrode 1 are linked, one end of the other end and neon tube and electric capacity links, the other end of neon tube and electric capacity and another electrode link, outside diode 4, be provided with shell body 3, for can lower at voltage (more than the 160V) or ambient temperature when low, fluorescent tube can start smoothly, can adopt the structure of embodiment 2 as shown in Figure 2: at the neon tube of the starter that high-power 2 utmost point pipes are housed and two ends normally open push button switch 5 in parallel of electric capacity, this switch can be loaded on the shell body 3, also available wire causes outside the shell body, push-button switch is in off-state usually, when the low starter in time of brownout (more than the 160V) or ambient temperature, and this switch of pressing, fluorescent lamp is starter in time, stops to press this switch and disconnects voluntarily.Figure is the electrical schematic diagram of embodiment 2, and KS is a normally open push button switch, and S is for only being equipped with the starter of neon tube and electric capacity, and diode adopts more than the high-power withstand voltage 400V, and the above semiconductor diode of electric current 3A 9 is as IN5407).3 of embodiment be with heavy-duty diode with after normally open push button switch is connected, be parallel to the two ends of neon tube and electric capacity, the starter of this kind structure, pressing switch can be when voltage 140V be above rapid build-up of luminance.Fig. 4 is the structural representation of embodiment 3, and the normal open switch 5 of this figure is to draw outside the housing with lead, is convenient to press switch when fluorescent lamp is loaded on eminence.Fig. 5 is the electrical schematic diagram of embodiment 3.
