Energy-saving controller capable of adjusting energy output automatically

Abstract

The invention discloses an energy-saving controller capable of adjusting energy output automatically. The controller is applied to a lighting lamp which comprises a power supply unit, a power storage unit and a load which are connected in turn; the controller comprises a sensing unit and an energy output control unit; the sensing unit is connected with the power storage unit and sends a signal to an energy output detecting unit according to a sensed output / input current of the power storage unit; and the energy output control unit is connected with the load and controls the operating power of the load. The controller adjusts the operating power of the load according to the change of remaining power of the power storage unit and can effectively distribute remaining storage power, thereby prolonging the using time of storage power and improving the stability and the continuity of lighting.

Description

technical field [0001] The invention belongs to the lighting field, in particular to an energy-saving controller capable of automatically adjusting energy output. Background technique [0002] At present, with the development of the industrial economy, the demand for electricity is increasing year by year. However, because coal is mostly used for power generation, and coal is a non-renewable resource, and coal combustion will produce a lot of waste gas and pollute the environment, all countries are looking for other solutions. Alternative resources, such as wind power generation, solar power generation, etc. Take wind power generation as an example. Although it is a clean energy source, due to different seasons and different wind speeds, the amount of power generation is variable and the voltage is unstable, so it is not easy to charge the battery. Stable, leading to shorten the service life of the battery; take solar power generation as an example, due to the variability of...

[0002] At present, with the development of the industrial economy, the demand for electricity is increasing year by year. However, because coal is mostly used for power generation, and coal is a non-renewable resource, and coal combustion will produce a lot of waste gas and pollute the environment, all countries are looking for other solutions. Alternative resources, such as wind power generation, solar power generation, etc. Take wind power generation as an example. Although it is a clean energy source, due to different seasons and different wind speeds, the amount of power generation is variable and the voltage is unstable, so it is not easy to charge the battery. Stable, leading to shorten the service life of the battery; take solar power generation as an example, due to the variability of natural weather, it will also cause the voltage instability of solar power generation, and the instability of wind power and solar power supply due to climate reasons will also make the workload (light source) not working properly and continuously

[0003] In order to solve the above problems, the current common practice is to equip electric energy at the same time. When the wind is weak or the weather is bad, the mains electricity is used to ensure the lighting of the lamps. However, this will also cause the consumption of electric resources to a certain extent, and there is still improvement Space

[0004] In view of the above analysis, there are still defects in the way of simply using wind energy or solar energy as energy sources, which cannot be promoted, and the use of electric energy has the disadvantages of not being environmentally friendly and energy-saving

[0005] Furthermore, due to the instability of wind power or solar power generation, when the weather conditions are not good, the power stored in the battery is too small to meet the lighting needs throughout the night. Therefore, the usual practice now is to regularly adjust the power of the light source. , such as setting the luminous power to be higher in the evening to 12 o'clock at night, and reducing the luminous power when there are fewer people and vehicles on the road in the middle of the night, although this approach can solve the problem of insufficient battery energy storage and all-night lighting to a certain extent. However, it is inflexible. For example, when the storage capacity of the battery is sufficient, there is no need to use this method, so it is still not flexible to adapt to the actual situation.
