Value is, for example, 0.1%.
Moreover, in the present embodiment, it is bigger than the second luminance delta (A) to be at least set to the first luminance delta (B)
((B)>(A)).It is this setting it is meant that when the usual ignition mode before mode will change brightness decline compared with, from
Usual ignition mode is changed into the moment for being always on mode at night, and bigger decline occurs for brightness.
If user is possible to be difficult to grasp when lighting device 100 is in the case where (A) and (B) is roughly equal
It is changed into night from usual ignition mode and is always on mode.However, by when making Mode change as above-mentioned brightness change
Variation increase compared to the variation before Mode change, user can clearly grasp lighting device 100 from usually lighting mould
Formula is changed into night and is always on mode.Thus, it is possible to prevent confusion below: although user's operation remote controler 200, not
Know whether the mode of lighting device 100 is changed into night from usual ignition mode and is always on mode.Therefore, present embodiment
Lighting device 100 improves the convenience of user, use feeling.
Also, from third illuminating state into the transformation of the 6th illuminating state, there is also defined luminance difference (variation
Amount), which is defined as third luminance delta.In Fig. 3, third luminance difference is equivalent to variable quantity (C).Variable quantity
(C) value is, for example, 0.2%.
Moreover, in the present embodiment, setting more preferably is set to the first luminance delta (B) greater than third
Luminance delta (C) ((B) > (C)).By this brightness change, user can more clearly grasp lighting device 100 from logical
Normal ignition mode is changed into night and is always on mode.Therefore, the lighting device 100 of present embodiment further improves user just
Benefit, use feeling.
Fig. 4 is an embodiment of brightness control, and Fig. 5 indicates the another embodiment of brightness control.In this reality
It applies in mode, during control unit 62 is so that usually ignition mode and night be always on the extinguishing for being provided with zero luminance between mode
Mode controls the brightness of light-emitting component 52.According to the present embodiment, extinguish between lighting device 100 is short-term, therefore user can
It more clearly grasps lighting device 100 and is changed into night from usual ignition mode and be always on mode.Thus, it is possible to prevent below
It is chaotic: although user's operation remote controler 200, to be not aware that the mode of lighting device 100 whether from usually having lighted mould
Formula is changed into night and is always on mode.Therefore, the lighting device 100 of present embodiment improves the convenience of user, use feeling.Figure
Luminance delta (A), (B), (C) of 5 embodiment can also determine in the same manner as the luminance delta (A) of Fig. 4, (B), (C)
It is fixed.
In addition, the pattern of Fig. 3, Fig. 4, brightness shown in fig. 5 are stored in storage unit 64, saved by the reading of control unit 62
Pattern.Also can storage unit 64 multiple patterns are stored in advance, allow the user to select any one pattern.
In addition, the bright of light-emitting component 52 can be controlled as follows under the usual ignition mode of Fig. 3, Fig. 4, Fig. 5
Degree: regardless of the degree of the brightness of lighting device 100, as long as user presses the button that the night of remote controler 200 is always on, control unit
62, which are just immediately transferred to night, is always on mode.
In addition, control unit 62 can control as follows lighting device 100: being changed into neither usual ignition mode
Nor when extinguishing mode that night is always on mode, that brightness is essentially zero and then existing last night are always on mode
Brightness.For example, in the case where night is always on mode, it is desirable to which the user's operation remote controler of zero luminance is changed into lighting device 100
Extinguishing mode.When remote controller is always on mode to revert to night to user again, can be lighted with brightness before.Storage
Night before the storage of portion 64 extinguishing mode is always on last brightness when mode, is always on when mode starts again at night by controlling
Portion 62 reads the brightness, and thus, it is possible to carry out this control.
In addition, under the extinguishing mode that brightness is essentially zero, the power supply that is in general supplied electric power to light-emitting component 52
Electrolytic capacitor 42 in portion 40 not accumulated charge (not charging).In addition, in the light modulation of the power saving as night is always on mode
Under mode, the duty ratio of lighting for lighting light-emitting component 52 is set to low value.This means that being responsible for electrolytic capacitor 42
The charging duty cycle of charging is also low, and charging will spend the defined time.
Therefore, it in previous lighting device, carries out in user from extinguishing mode to the province as night is always on mode
In the case where the transition operation of the light-modulating mode transformation of electricity, the starting to light of light-emitting component 52 is also required to the defined time, thus
Can be imagined can bring whether such as device has occurred confusion as failure to user.
Fig. 6 is to indicate charging duty cycle, light duty ratio and the timing diagram of the relationship of the illuminating state of lighting device, Fig. 6
(a) be the timing diagram indicated in above-mentioned previous lighting device.It is desirable that based on by the operation of user and from remote control
The mode switching signal that mode is always on from extinguishing mode to night that device 200 is sent, starts to come into effect to electrolytic capacitor
The charging duty cycles of 42 chargings, periodically starting night together is always on lighting under mode with beginnings of lighting duty ratio.However, such as
Shown in (a) of Fig. 6, due to above-mentioned reason, when can generate the defined delay from reception pattern switching signal until lighting
Between tg1.In particular, delay time tg1During charging duty cycle obtained from performance (charging time) than considering electrolytic capacitor
t1(such as 1.5 seconds) are long.
(b) of Fig. 6 indicates the timing diagram of the lighting device 100 of present embodiment.In order to release problem as described above,
In present embodiment, control unit 62 is according to the charging shape of the electrolytic capacitor 42 of the power supply unit 40 supplied electric power to load portion 50
State to control the power supply carried out by power supply unit 40, and controls the charging duty cycle of electrolytic capacitor 42, light-emitting component 52
Light duty ratio.
Under the extinguishing mode that brightness is essentially zero, electrolytic capacitor 42 is in the uncharged state not being electrically charged.
Receiving unit 66 receives the mode switching signal that mode is always on from extinguishing mode to night from remote controler 200 in this state, with this
Control unit 62 controls power supply unit 40 simultaneously, with it is defined light duty ratio electrolytic capacitor 42 made promptly charge defined when
Between, it thus charges in advance, to release starting (lighting) delay.In particular, in the case where this power supply unit 40 is always on mode with night
The duty ratio of lighting of the upper limit is charging duty cycle, starts to charge to electrolytic capacitor 42.But it is not necessarily intended to night being always on mould
The duty ratio of lighting of the upper limit under formula is set as charging duty cycle, can both be greater than the lighting for the upper limit that night is always under mode and account for
Empty ratio, might be less that the upper limit that night is always under mode lights duty ratio.As long as control unit 62 controls electricity as follows
Source portion 40: after starting from the extinguishing mode of zero luminance to the transformation of the second light-modulating mode, than being changed into the second light modulation
The big duty ratio of lighting of duty ratio of lighting after mode is charging duty cycle, to start to charge to electrolytic capacitor 42.
As a result, starting the delay time t of (lighting) shown in (a) with Fig. 6g1It compares, delay time becomes shorter
tg2, to mitigate the delay of starting (lighting).For example, the charging of electrolytic capacitor 42 is with the delay time than 1.5 seconds or more
tg11 second short delay time tg2It completes, starts lighting for light-emitting component 52.And in 0.5 second (t2=t1-tg2) after, transformation
It is always under mode for night and lights (brightness stored in storage unit 64).In particular, the upper limit of mode is always on night herein
Brightness, i.e. 1.5% brightness light t2Second (referring to " when uncharged " of (b) of Fig. 6).
On the other hand, it is changed under night is always on situation as mode from usual ignition mode, there is also electrolysis electricity
These state unified definitions (are " completely to fill by the horizontal situation that container 42 is charged to quota or is charged to a certain degree
When electric ").
In this case, receiving unit 66 receives the mode switching signal from remote controler 200 (such as from usual ignition mode
The mode switching signal of mode is always on to night), control unit 62 controls power supply unit 40 at the same time, makes light-emitting component 52 to provide
Duty ratio of lighting light the defined time.Here, lighting t with brightness, i.e. 1.5% brightness that night is always on the upper limit of mode3
Second (being herein 1.5 seconds) (referring to " when the full charge " of (b) of Fig. 6).
That is, being charged to the horizontal situation more than to a certain degree in electrolytic capacitor 42 in previous lighting device
Under, if directly starting to light duty ratio, light-emitting component 52 can be made with Intensity LEDs corresponding with the degree of charging, it can to have
The problems such as flashing caused by the brightness because of a flash can occur.However, in the present embodiment, be changed into night be always on mode it
The lighting time of preceding adjustment light-emitting component 52 and brightness, thus, it is possible to reduce the brightness because of a flash caused by flash, prolonging of lighting
Late, to without incongruity light.
In the present embodiment, light-emitting component 52 is in t2=0.5 second, t3With night in the range of time as=1.5 seconds
The brightness (specifically 1.5%) for being always on the upper limit of mode shines.If it is this time and brightness, then user does not allow susceptible
To uncoordinated.That is, when being always on Mode change to night from extinguishing mode, t2=0.5 second, therefore 1 from after remote controller
It is just lighted after second with the upper limit that night is always on mode, therefore user is not easy to feel inconsistent.In addition, from usual ignition mode
When being always on Mode change to night, it can be always on the brightness of the upper limit of mode from night to night and be always on Mode change, therefore
Be switched to night be always on after mode there is no the brightness because of a flash caused by flashing, user is not easy to feel uncoordinated.
In addition, as another embodiment, also can control unit 62 according to be changed into night be always on it is usual before mode
The lighting time of ignition mode measures the time for lighting duty ratio before transformation, and filling for electrolytic capacitor 42 is assumed based on this
The electric time, to adjust the charging for lighting and light the time of duty ratio.
In addition, the lighting device 100 of present embodiment has upper illumination region 110, lower illumination region 120, central blaze portion 130
The system of these three light sources, but it is not particularly limited in this mode, it also can be using this for the lighting device of a system
Invention.In addition, being not necessarily limited in the case where night is always on mode that only central blaze portion 130 lights such control, can also pass through
Upper illumination region 110, lower illumination region 120, these three systems of central blaze portion 130 realize that night is always on mode.In addition, illumination dress
The physical circuit for setting 100 is also not limited to circuit shown in Fig. 2.
In addition, in the present embodiment, the first light-modulating mode is corresponding with usual ignition mode, the second light-modulating mode and night
It is corresponding to be always on mode.However, the first light-modulating mode, the second light-modulating mode are not limited to this mode.For example, it can be, the
One light-modulating mode is full ignition mode, and the second light-modulating mode is battery saving mode.In addition, also can be in addition to the first light-modulating mode,
