Make the disclosure is understood more thorough comprehensively.
Referring to Fig. 1, it is the light-dimming method of illuminating lamp of one embodiment of the invention, and it comprises the following steps:
Step S101, illuminating lamp works on power, and drives light source luminescent according to current brightness level.Wherein illuminate
In lamp, storage has multiple predetermined luminance grades, current brightness level and the first preset threshold condition being circularly set,
Described current brightness level is in multiple described predetermined luminance grade.Predetermined luminance grade can be to adjust
Optical parameter, it is also possible to be to dim the numbering that parameter is corresponding.
In the present embodiment, the brightness degree of illuminating lamp has Pyatyi, respectively highest luminance brightness
100%, 80%, 60%, 40%, 20%, and can change successively according to the loop direction that brightness is gradually reduced.
The current brightness level of illuminating lamp is first order brightness degree, i.e. the 100% of highest luminance brightness, light after powering on
Source is luminous with first order brightness degree.
Step S102, the power-off time length of detection power supply signal.
Specifically, under switch is in the conduction state, switch is opened the most rapidly after user's closing switch, so
Just an of short duration power-off time length is created.In the present embodiment, first described power supply signal is carried out rectification,
After voltage stabilizing and amplitude limit output process, then detect the power-off time length of power supply signal, i.e. detect low level time
Length.
Step S103, when described power-off time length meets the first preset threshold condition, according to being circularly set
Multiple described predetermined luminance grade in be positioned at described current brightness level next predetermined luminance grade drive
Light source luminescent, and update described current brightness level.
Specifically, when power is off between length when meeting the first pre-set threshold value condition, storage current preset brightness etc.

As the arc time is usually 0～80 millisecond.And the present invention avoids this arc time, then can avoid multiple product
Control asynchronous problem when using simultaneously.I.e. in the case of a multiple illuminating lamp of switch control rule, if the
Under the conditions of one pre-set threshold value in limited time between too short, then easily because noise, such as phenomenon of arc discharge cause power-off the most thorough
The end etc., cause partial illumination lamp mistake to dim, and then cause one to open the light the multiple lighting brightness controlled not
Situation about synchronizing occurs.And 200 milliseconds had both adapted to the custom time span that staff operation switchs, ensure again to adjust
The sensitivity of light.Limit overlong time under the conditions of first pre-set threshold value and then can reduce light modulation sensitivity.
In another embodiment, illuminating lamp also stores the second pre-set threshold value condition, when described power-off time
When length meets the second preset threshold condition, change the loop direction of multiple described predetermined luminance grade.Will
The loop direction of the illumination brightness levels being gradually reduced brightness changes to be gradually increased the illumination brightness levels of brightness
Loop direction, or change to be gradually increased by the loop direction being gradually reduced the illumination brightness levels of brightness
The loop direction of the illumination brightness levels of brightness.Hereafter when power-off time length meets the first threshold values condition every time,
Illuminating lamp can change brightness degree according to described loop direction.
Described second preset threshold condition is that power-off time length is more than 1 second and less than 5 seconds.Wherein, more than 1
The power-off time length of second can substantially separate with the power-off time length of change lighting brightness grade and come.
Illuminating lamp is provided with overtime protection mechanism, regards the power-off time length being longer than 5 seconds as faulty operation signal,
And do not carry out any operation.Draw through statistical practical experience, in 5 seconds, do not carry out any operation, logical
Is often all owing to the notice of operator is the most transferred, have forgotten continuation operation, therefore will be longer than 5 seconds disconnected
