Brief description of the drawings
Fig. 1 is the step flow chart of the light-dimming method of one embodiment of the invention light fixture；
Fig. 2 is the functional block diagram of another embodiment of the present invention light fixture.
Embodiment
As shown in figure 1, its step flow chart for the light-dimming method 10 of one embodiment of the invention light fixture.Light-dimming method 10 wraps
Include：
Step S101, work on power and initialize.In actual applications, work on power and switched for illuminating lamp by off-position
For "on" position, it can be understood as, user operable switch, illuminating lamp and supply line are switched from the off-state of electrical connection
For the conducting state of electrical connection so that illuminating lamp is in the state that works on power.In the present embodiment, the initialization in step S101
Action includes initializing default flag bit in memory.For example, default flag bit is 0 or 1, the mark before working on power
Position is 1, and initialization action is that flag bit 1 is initialized as into flag bit 0.In other embodiments, it is not marked with before working on power
Will position, it also can determine that the mark for working on power and starting for light-dimming method 10.
Step S102, call the memory light modulation driving parameter illuminating lamp work in memory.Memory dims parameter
The parameter of adjusting illuminating lamp brightness, or the parameter of adjusting illuminating lamp colour temperature.By calling the memory in memory to dim
Driving parameter illuminating lamp so that illuminating lamp is worked with brightness corresponding with memory light modulation parameter or colour temperature.
Step S103, continue responding to switch switching action and produce control instruction, the switch switching action is switch by connecing
Lead to after going off and connect again.For example, the switch is button switch, ship type switch, pullswitch etc., or by distant
Control the switch switched on and off.In actual applications, according to user operable switch by connect go off after again connect
Switching action, produce control instruction.For example, control instruction is the signal of low and high level conversion.
Step S104, first control instruction is responded, calls the initial light modulation driving parameter institute in the memory
Illuminating lamp work is stated, and the memory parameter is updated to the initial light modulation parameter.First control instruction refers to shine
After bright lamp works on power, user's first time Operation switch by connect go off after the switching action connected again and caused control
Instruction.In actual applications, illuminating lamp work described in the initial light modulation driving parameter in the memory is called to refer to illumination
Lamp is resetted, if illuminating lamp includes multiple LEDs, electricity of this multiple LED corresponding to all in accordance with initial light modulation parameter
Signal shows with corresponding brightness or colour temperature, avoid because interference or some LED internal errors cause it is asynchronous, afterwards then
Understand nonsynchronous problem always.
Step S105, responds second and the control instruction afterwards performs default light modulation action, and by described in
Memory light modulation parameter is updated to currently dim parameter.Second and the control instruction afterwards refer to first control
After instruction, user operable switch by connect go off after the switching action connected again and caused control instruction.By described in
It is in order to preserve the current light modulation parameter, in case illuminating lamp works on power next time that memory light modulation parameter, which is updated to currently dim parameter,
When carrying out step S102 afterwards, the current light modulation driving parameter illuminating lamp work is called.So, user can will pass through light modulation and act
Select the brightness liked or colour temperature to save, facilitate brightness that illuminating lamp is liked after being once again powered up with user or colour temperature to show.
Also include between the step S104 and the step S105：Respond first control instruction dirty bit
The step of.For example, flag bit 0 is revised as flag bit 1.In the step S105, described second and afterwards is being received
After the control instruction, before performing default light modulation action, in addition to judge whether the flag bit meets preparatory condition,
And the default light modulation action is performed when the flag bit meets preparatory condition.For example, whether judgement symbol position is 1, such as
Fruit flag bit is 1, illustrates to have received one or several control instructions before this control instruction is received, and to illuminating lamp
Resetted, and then just perform default light modulation action.
In the step S104 after first control instruction is responded, in addition to judge whether the flag bit accords with
The step of closing the preparatory condition, and call when the flag bit does not meet the preparatory condition initial in the memory
Illuminating lamp work described in driving parameter is dimmed, and the memory parameter is updated to the initial light modulation parameter.For example, judge mark
Whether will position is 1, if flag bit is not 1, that is to say, that when flag bit is 0, just calls the initial light modulation parameter in memory
Drive the illuminating lamp to work, and the memory parameter is updated to the initial light modulation parameter.
Light modulation action in the step S105 is to adjust in the stage for calling multiple different stages in the memory
Illuminating lamp work described in the stage light modulation driving parameter more other than the memory light modulation high one-level of parameter in optical parameter.For example,
The brightness that the stage light modulation parameter of five different stages corresponds to illuminating lamp is followed successively by：100 candelas/square metre, 150 candelas/
Square metre, 200 candelas/square metre, 250 candelas/square metre and 300 candelas/square metre.So, user passes through operation
Switch does switching action and produces control instruction, sequentially to call the stage of above-mentioned five different stages light modulation parameter to adjust photograph
The brightness of bright lamp becomes big or from diminishing successively greatly successively from small.And for example, the stage light modulation parameter of five different stages is corresponding shines
The colour temperature of bright lamp is followed successively by：2000 Kelvins, 3000 Kelvins, 4000 Kelvins, 5000 Kelvins and 6000 Kelvins.This
Sample, user does switching action by Operation switch and produces control instruction, sequentially to call the stage of above-mentioned five different stages
Light modulation parameter carrys out the colour temperature of adjusting illuminating lamp and becomes big or from diminishing successively greatly successively from small.
The selection for carrying out brightness regulation by switching switching action in order to facilitate user and still carrying out colour temperature regulation, light modulation side
Method 10 also includes judging whether receive the 3rd control instruction in the preset time for receiving second control instruction,
If so, then the light modulation action is brightness regulation, if it is not, then the light modulation action is adjusted for colour temperature.Or according to practical application
Needs, light-dimming method 10 include judge the 3rd institute whether is received in the preset time for receiving second control instruction
Control instruction is stated, if so, then the light modulation action is adjusted for colour temperature, if it is not, then the light modulation action is brightness regulation.For example,
The preset time is 2 seconds.
