[0003] Therefore, under the demand of advocating energy saving, it is adopted to reduce the power consumption of street lamps by lighting lights at intervals during the off-peak hours of passers-by and vehicles. The purpose of reducing power consumption, but it also makes the lighting divided into light and dark areas, and there are some dangers in dark areas

Embodiment Construction
[0029] The method for controlling the brightness of a light source in a preferred embodiment provided by the present invention is taken as an example to control the brightness of road lamp 1 in this embodiment (such as figure 2 shown), but not limited thereto. The street lamp 1 includes a light source 10 and a controller 20. The light source 10 in this embodiment is an LED lamp, but it is not limited thereto. The controller 20 controls the brightness of the light source 10 to save power consumption. The method used to control the brightness of the light source comprises the following steps:
[0030] Such as image 3 As shown, at a start-up time point T on with a closing time point T off Set a reference time point T between rf , the light source 10 at the starting time point T on open, and at the close time point T off Go out; and set the controller 20 to record the start time point T on with the turn-off time point T off period between.
[0031] Such as Figure 4 As...

Provided is a method for controlling light source luminance. The method for controlling the light source luminance includes the following steps: A. A reference time point is set between a turn-on time point and a turn-off point, the light source is turned on at the turn-on time point and is turned off at the turn-off time point; B. A first time range is formed in a way that the reference time point extends forward and not exceeds the turn-on time point, and an energy-saving range composed of a second time range is formed in a way that the reference time point extends backward and not exceeds the turn-off time point; C. A whole-lighting range is set between the turn-on time point and the turn-off time point and is a time range except from the energy-saving range, and the luminance when the light source positioned at the energy-saving range is weaker than the luminance when the light source positioned at the whole-lighting range. The energy-saving range of the method for controlling the light source luminance is a fixed time range and can not displace with changes of the power switch time.
Description
technical field [0001] The present invention is related to energy saving, and more specifically refers to a light source energy-saving module and an energy-saving method thereof. Background technique [0002] In order to take into account the safety of pedestrians walking or vehicles passing by at night, the street lamps on both sides of the road are all lit up at a fixed time in the evening. With the development of the road, the number of street lamps required is increasing day by day. At night, the electricity and money it consumes is relatively huge. [0003] Therefore, under the demand of advocating energy saving, it is adopted to reduce the power consumption of street lamps by lighting lights at intervals during off-peak hours of passers-by and vehicles. The purpose of reducing power consumption, but it also makes the lighting divided into light and dark areas, and there are some dangers in dark areas. [0004] In order to prevent street lighting from being divided in...
