The HID lamp is with becoming power energy-saving type Inductive ballast
Technical field:
The utility model relates to the lighting apparatus technical field, particularly relates to the change power energy-saving type Inductive ballast of high-voltage gas discharging light.
Background technology:
Existing many public places illumination, traditional Inductive ballast has only a winding, and its illumination operational mode is to carry out the rated power illumination in the whole time period, adopts this mode to cause a large amount of waste of energy.For example, rare the spacious people of car at midnight, from the statistics angle, at this moment people are reducing the demand of illumination resource, so there is no need fully light source is set in operation under the rated power state.On the other hand, since the phase at a low ebb of electricity consumption after midnight, the corresponding rising of voltage meeting of electric power system, generally reach more than the 240V, caused light-source brightness not fall counter increasing, the voltage of rising not only causes the increase of copper loss, iron loss, further waste the energy, also shortened light source life.
Summary of the invention:
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of change power energy-saving Inductive ballast is provided.
For achieving the above object, the technical scheme that the utility model provides is (referring to implementing illustration): include Inductive ballast (1), intelligent control system (2), electronic trigger (3), it is characterized in that: the secondary coil B of Inductive ballast (1) is connected with power supply L end, main coil A is connected with power supply L end by the K switch of intelligent control system (2), electronic trigger (3) is connected in series with Inductive ballast (1), bulb and Inductive ballast (1) also are connected in series, and capacitor C and Inductive ballast (1) are connected in parallel.
The utility model in normal working conditions, K switch is in closure state, electric current is lighted lamp under the effect of electronic trigger only by main winding A, this moment, bulb was in the rated power operating state; According to the default time, under the effect of intelligent control system 2, K switch disconnects, and this moment, electric current flow through main winding A and auxiliary winding B, because the increase of inductance value, line current reduces, and bulb is in and falls the power operating state, has reached the purpose of saves energy.
Description of drawings:
Fig. 1 is an electric theory structure schematic diagram of the present utility model.
Embodiment:
Referring to accompanying drawing 1:
Present embodiment is made up of three parts: the one, and Inductive ballast has been considered rational magnetic circuit mechanism and ferromagnetic material during design, self energy consumption of ballast has been reduced about 35%; The 2nd, intelligent control system, this circuit is provided with the time preset port, makes ballast change inductance value automatically by the condition that presets the power of lamp is also changed thereupon; The 3rd, electronic trigger makes it export the trigger impulse (amplitude and width) of the bulb that connects.The secondary coil B of Inductive ballast 1 is connected with power supply L end, main coil A is connected with power supply L end by the K switch of intelligent control system 2, electronic trigger 3 is connected in series with Inductive ballast 1, and bulb and Inductive ballast 1 also are connected in series, and capacitor C and Inductive ballast 1 are connected in parallel.
The utility model is to utilize the improvement of light source operational mode to reach saves energy and operating cost purpose, i.e. the inductance value conversion of main winding A by Inductive ballast 1 and auxiliary winding B realizes the variation of the power of lamp, increases inductance value constant power is descended.The Power Conversion of ballast is made as two grades, i.e. rated power and fall the power shelves, and power switches realizes that by intelligent control system 2 K switch is in closure state under the normal condition, only by main winding A, bulb is in the rated power operating state to electric current; Under the effect of intelligent control system 2, according to pre-conditioned, K switch disconnects, and this moment, electric current passed through main winding A and auxiliary winding B, because the increase of inductance value, line current reduces, and bulb is in and falls the power operating state.Owing to reduced bulb and ballast oepration at full load time, the useful life of ballast, bulb and annex is prolonged.
