Abstract
The utility model relates to a light-modulation ballast for a high-intensity gas discharge lamp. One end of a line pack winding of a relay 3 is connected with the zero line of commercial power, and the other end of the line pack winding of the relay 3 is connected with a control line 2; the other end of the control line 2 is connected with a switch; the other end of the switch 1 is connected with the fire line of the commercial power after the other end of the switch 1 is connected in parallel with the reed leading out end of the relay 3; a normally-closed contact 4 of the relay 3 is connected with one end of an inductance ballast 8, and a normally-open contact 5 of the relay 3 is connected with the tap end of the inductance ballast 8; the other end of the inductance ballast 8 is connected in parallel with a lamp 6 and one end of a starter 7; the lamp 6 and the other end of the starter 7 are connected with the zero line of the commercial power. The light-modulation ballast for a high-intensity gas discharge lamp has the advantages of simple and compact structure, convenient manufacture and installation, low cost, long service life, etc. The utility model can effectively regulate the brightness of a high-intensity gas discharge lamp.
Description
The utility model relates to the inductance type ballast that a kind of high-intensity gas discharge lamp is used, especially the high-intensity gas discharge lamp dimming ballast.
High-intensity gas discharge lamp is a negative-resistance device, needs ballast restriction electric current.Gaseous discharge lamp all is ballast of series connection before lamp at present, starter in parallel at the gaseous discharge lamp two ends, and the power of lamp can't be regulated.The startup stage since modulating voltage low, starting current is 1.5 to 2 times of normal lamp current, and is very big to the lamp export license, shortened the lamp life-span.In the supply voltage rising time after midnight, the ballast electric current increases as street lighting, and lamp surpasses rated power work, has reduced the lamp life-span.And the time after midnight Pedestrians and vehicles seldom, it also is waste to the energy that total power is lit a lamp.In the patent disclosure of number of patent application 96190272 " a kind of ballast for discharge lamp ", exist the high weak point of complex structure cost.
The purpose of this utility model provides a kind of simple in structure, can not only limit electric current, and can effectively adjust electric current, to reach the high-intensity gas discharge lamp dimming ballast of realizing the light modulation purpose.
The purpose of this utility model is achieved in that and includes lamp, Inductive ballast, relay, starter composition.The end that its relay line holds group is connected with the civil power zero line side, another termination control line, the other end of control line is connected with switch (can be manual or automatic switch), be connected with the civil power live wire after the reed exit parallel connection of the other end of switch and relay, the normally-closed contact of relay is connected with Inductive ballast one end, normally opened contact is connected with the tap terminals of Inductive ballast, one end of the other end of Inductive ballast and lamp and starter is connected in parallel, and the other end of lamp and starter is connected with the civil power zero line.
Two windings lamp under the triggering of starter that the utility model operation principle, the power supply normally-closed contact by relay flows through Inductive ballast is activated, the startup stage lamp be in the half-power state; If when needing capacity operation, control line inserts power supply by switch, and relay is got, its normally-closed contact disconnects, and the normally opened contact adhesive is to the tap terminals of Inductive ballast, and the number of turn of Inductive ballast reduces, AC impedance reduces, and lamp enters the full power state operation, is purpose to reach light modulation.
Because adopt technique scheme, dimming ballast has simple and compact for structure, fabrication and installation are convenient, and cost is low, and the life-span is long, can effectively regulate the characteristics such as brightness of high-intensity gas discharge lamp.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is another example structure schematic diagram of the present utility model.
Among the figure: the former ballast of 1-switch 2-control line 3-relay 4-normally-closed contact 5-normally opened contact 6-lamp 7-starter 8-Inductive ballast 9-
As shown in Figure 1, an end and the civil power live wire that switch 1 control line 2 and relay 3 are in series joins, the other end and civil power zero line join, the normally-closed contact 4 and Inductive ballast 8 one ends of relay 3 join, normally opened contact 5 joins with the tap terminals of Inductive ballast 8, one end of the other end of Inductive ballast 8 and lamp 6 and starter 7 joins, and the other end and the civil power zero line of lamp 6 and starter 7 join.
Fig. 2, an end and the civil power live wire that switch 1 control line 2 and relay 3 are in series joins, the other end and civil power zero line join, the civil power live wire is in series with Inductive ballast 8 and original ballast 9, original ballast 9 other ends join with lamp 6 and starter 7 one ends, the other end of lamp 6 and starter 7 and civil power zero line join, and two exits of the normally opened contact 5 of relay 3 join with Inductive ballast 8 two ends respectively.
Claims (1)
- A kind of high-intensity gas discharge lamp dimming ballast, include lamp 6, Inductive ballast 8, relay 3, starter 7 is formed, the line that it is characterized in that relay 3 holds group one end and is connected with the civil power zero line, another termination control line 2, the other end of control line 2 is connected with switch 1, be connected with the civil power live wire after the reed exit parallel connection of the other end of switch 1 and relay 3, the normally-closed contact 4 of relay 3 is connected with Inductive ballast 8 one ends, normally opened contact 5 is connected with the tap terminals of Inductive ballast 8, one end of the other end of Inductive ballast 8 and lamp 6 and starter 7 is connected in parallel, and the other end of lamp 6 and starter 7 is connected with the civil power zero line.
