Problems solved by technology

There is a problem with this timing dimming ballast that there is a big difference in the time of darkness between winter and summer, and there is also a big difference in the peak time of people's evening activities, so using the same set time in winter and summer will give Inconvenience caused by people's travel and various activities
In order to overcome this defect, as an improved version of this technology, an additional switch (patent 201120168903.2) is used. When the season changes, the manual switch is used. This method has a huge workload and is not practical. Another improvement is to use wireless And infrared remote control (such as patent 201120164108.6), to install infrared or wireless remote control for each ballast, one is the increase in cost, and secondly, it is also a lot of work to manually switch each ballast on-site remote control

Embodiment 1

[0016] Such as figure 1 , the ballast is connected to the energy saver, the 220V power supply is connected to the dimming control circuit, ballast and lamp tube through the inductor, the ballast generates high voltage to break down the lamp tube to start the street lamp, the dimming control circuit is connected to the relay, and the relay is connected to the inductor , the dimming circuit includes a microcontroller, a memory, and peripheral circuits, etc. The microcontroller can set a variety of delayed dimming modes. In this embodiment, four delayed dimming modes are set:

[0017] Mode 1, turn on the light at 18:00 every day, delay 5 hours to reduce to half power operation, and reduce to 0 power after 11 hours of lighting (that is, turn off the light).

[0018] Mode 2, turn on the light at 19:00 every day, delay 4 hours to reduce to half power operation, and reduce to 0 power after 9 hours of lighting (that is, turn off the light).

[0019] Mode 3, turn on the light at 18:00...

Embodiment 2

[0023] Compared with Embodiment 1, this embodiment adds a light-off relay, mainly because when the mode conversion is required, the street light can be turned off by the light-off relay (because the sky is already bright at this time) when it is time to turn off the light normally. However, the power supply of the circuit is not turned off, and the circuit continues to be energized, so that the power-on time recorded by the microprocessor exceeds the preset switching time, thereby changing the dimming mode. Both the dimming mode and the dimming method are the same as those in Embodiment 1.

Embodiment 3

[0025] The difference between this embodiment and Embodiment 1 is that the voltage regulation circuit is controlled by the dimming control circuit, and the voltage connected to the ballast is adjusted to change the output power of the ballast: at the same time, the dimming mode set is also the same as Different from Embodiment 1, this embodiment sets four delay dimming modes:

[0026] Mode 1, turn on the light at 18:00 every day, delay 3 hours to reduce to 90% power operation of full power, delay 5 hours to reduce to half power operation, and reduce to 0 power after 11 hours of lighting (that is, turn off the light).

[0027] Mode 2, turn on the light at 19:00 every day, delay 2 hours to reduce to 90% power operation of full power, delay 4 hours to reduce to half power operation, and reduce to 0 power after 9 hours of lighting (that is, turn off the light).

[0028] Mode 3, turn on the light at 18:00 every day, delay 3 hours to reduce to 90% power operation of full power, dela...

Abstract

The invention discloses a variable power economizer used for adjusting light of a street lamp. The variable power economizer used for adjusting light of the street lamp comprises an inductor which can adjust inductance and a light adjusting control circuit. The light adjusting control circuit is connected with a relay which is used for adjusting the size of inductance of an inserted circuit. The light adjusting control circuit comprises a microprocessor and a memorizer. Multiple light adjusting modes are stored inside the memorizer. When the microprocessor is started, an intraday light adjusting mode is invoked, and the size of the inductance of the inserted circuit is controlled through the relay according to the light adjusting mode and time of light off needed in the day. When the light adjusting mode needs to be changed, intraday extended power on time of the mode is changed to set conversion time. The microprocessor records power on time of a ballast everyday, if the power on time recorded in the day is less than the set conversion time, the light adjusting mode is not changed, if the power on time recorded in the day is more than the set conversion time, a mode record of the memorizer is changed by the microprocessor to a next group of light adjusting mode, and the microprocessor invokes the changed light adjusting mode in the following day.

Description

[0001] technical field [0002] The invention relates to an energy saver, especially an energy saver used in street lamp ballasts. Background technique [0003] The application of timing dimming ballasts to road lighting has achieved good social and economic benefits. Timing dimming ballasts use full power lighting during periods when there is a large flow of people and vehicles (such as 18:00-23:00). , and from midnight to early morning (23:00-6:00 the next morning) the lighting power is reduced to save electricity during the period when there is less traffic. There is a problem with this kind of timing dimming ballast, that is, because of the great difference in the time of darkness in winter and summer, and the peak time of people's evening activities, there is also a big difference, so using the same set time in winter and summer will give People's travel and various activities bring inconvenience. In order to overcome this defect, as an improved version of this techno...
