[movement]
Fig. 4 is the time diagram for indicating the movement of lighting device 10 involved in present embodiment.Here, as shown in figure 4, from
When lighting power control signal become low level (power supply connection) rise until in light source 12 start streaming current (source current)
Until time T1 ratio from extinguish when power control signal become high level (power supply disconnection) until not flowed in light source 12
Time T2 long until streaming current.
Here, capacitor 18 shown in Fig. 3 needs to charge when lighting.On the other hand, when extinguishing, electricity shown in Fig. 3
Container 19 discharges.The capacitor of the capacity ratio capacitor 19 of capacitor 18 is big, therefore lights needed for required time T1 ratio extinguishes
Time T2 long.Such as time T1 is 500m seconds or so, time T2 is 10m seconds or so.In addition, numerical example is one listed herein
Example, the present invention is not limited to the numerical examples.This is also identical in the numerical example being exemplified below.
In this way, it is very long compared with the time T2 needed for extinguishing to light required time T1.It is leaned on as a result, from user by hand
Nearly proximity sensor 14 rise time until power control signal switching it is roughly equal in the case where, it is from user that hand is close
Proximity sensor 14 rise time ratio until light source 12 is lighted from user by hand close proximity to sensor 14 until light source
Time until 12 extinguishings is long.
On the other hand, in the present embodiment, as shown in figure 4, make from when lighting user by hand close proximity to sensing
Device 14 rise until power control signal switching until time T4 ratio from extinguish when user by hand close proximity to sensor 14
Time T5 until power control signal switching is short.Object is detected by proximity sensor 14 from OFF state as a result,
Body rise by time T4 and time T1 and light source 12 light the spent reaction time (T0) with from illuminating state by approaching
Sensor 14 detects reaction time (T0) the substantially phase that object is by time T5 and time T2 and the extinguishing of light source 12 is spent
Deng.
Here, the roughly equal degree for referring to the time difference as low as user imperceptible time difference.For example, roughly equal refer to
Time difference is 200m seconds hereinafter, it is preferred that referring to that the time difference is 100m seconds or less.
In addition, light source 12, which is lighted, refers to that the light quantity of light source 12 is greater than pre-determined first threshold.For example, the first threshold
It is the light quantity that user can be identified as the degree that light source 12 is lighted.In addition, light source 12, which extinguishes, refers to that the light quantity of light source 12 is less than in advance
The second threshold first determined.Such as the second threshold is the light quantity for the degree that user is identified as the extinguishing of light source 12.
Specifically, as shown in figure 4, proximity sensor 14 is using the pre-determined release of cycle T 3 as the luminous of electromagnetic wave
Pulse detects the reflection electromagnetic wave of each cycle T 3, thus the detection object within each period.Such as the cycle T 3 is a 125m seconds left sides
It is right.Control unit 13 continuously detects object within four periods by proximity sensor 14 when light source 12 is in OFF state
In the case of, light source 12 is lighted.In addition, control unit 13 when light source 12 is in illuminating state by proximity sensor 14 in five weeks
In the case where continuously detecting object in phase, light source 12 is extinguished.
Specifically, there is control unit 13 voltage level that will test signal to be compared with pre-determined threshold voltage vt
Compared with comparator.Control unit 13, in the case where the voltage level for detecting signal is greater than threshold voltage vt, is sentenced in each cycle T 3
Break to detect object in the cycle T 3.
Here, the quantity of LED pulse used in determining is more, the precision of detection is higher, is able to suppress error detection.Separately
On the one hand, the quantity increase of LED pulse used in making to determine cause from user by hand close proximity to sensor 14 until light
Time until source 12 is lighted or extinguished increases, therefore unsatisfactory.In this way, making to determine that the quantity of used LED pulse increases
Add that there are trade-off relations.
On the other hand, in the present embodiment, as described above, by for reaction time T0 when making to extinguish and when lighting
The remaining period that is equal and generating is assigned as detection and uses.Substantially do not increase reaction time T0 as a result, and can extinguish
Shi Tigao detection accuracy.Also, in the case where mistakenly having carried out extinguishing movement, it is possible to which user can not confirm the shape of surrounding
Condition, therefore detection accuracy when extinguishing is particularly important compared to detection accuracy when lighting.In the present embodiment, due to residue
Period be assigned to detection when extinguishing and use, therefore there is detection essence when can be improved the high extinguishing of different degree like this
Spend such effect.
In addition, in the above description, the quantity for describing the LED pulse used when lighting is four times, makes when extinguishing
The quantity of LED pulse is five examples, as long as but the quantity of LED pulse that is used when lighting than when extinguishing
The quantity of the LED pulse used is few, can be arbitrary number.Extinguish that is, control unit 13 is in light source 12
It will in the case where continuously detecting object in N1 period (natural number that N1 is 1 or more) by proximity sensor 14 when state
Light source 12 is lighted.In addition, control unit 13 when light source 12 is in illuminating state by proximity sensor 14 N2 period (N2 be than
N1 big natural number) in continuously detect to extinguish light source 12 in the case where object.
In addition, in the above description, the example roughly equal with reaction time T0 when lighting when describing extinguishing, still
It does not need certain roughly equal.As described above, being made by being less than the quantity of the LED pulse used when lighting when extinguishing
The difference of the quantity of LED pulse, the reaction time in reaction time and the when of lighting when thus extinguishing is reduced.Thereby, it is possible to realities
It now at least can reduce effect as the difference in the reaction time that user feels.
[variation]
In Fig. 4, the example for periodically discharging LED pulse is described, but is using the wireless situations such as microwave
Under, wireless signal can also be continuously exported as shown in Figure 5.In this case, control unit 13 is being examined as shown in Figure 5
It surveys in the case that signal continuously exceeds threshold voltage vt during time T4 and lights light source 12, in detection signal in the time
Light source 12 is extinguished in the case where continuously exceeding threshold voltage vt during T5.
In addition, as shown in fig. 6, the quantity of the LED pulse used when lighting and when extinguishing can also be identical.In the feelings
Under condition, control unit 13 is determined to have after object to continuous defined number (being four times in Fig. 6), when extinguishing by pre-
Voltage control signal is switched to high level (power supply disconnection) after the stand-by time T6 first determined.
In addition, when lighting and when extinguishing, the duty ratio of LED pulse is identical, but can also be different in Fig. 4 etc..
In addition, the duty ratio of the LED pulse in each period can also be different.For example, control unit 13 can also detect detection signal
Voltage level be more than threshold voltage vt timing stop LED pulse output.Thereby, it is possible to realize electric power saving.
In addition, in the above description, proximity sensor 14 exports analog voltage as detection signal, but can also be with mould
The output of quasi- voltage exports digital value together, or replaces analog voltage and export digital value.In this case, in control unit 13
It will test signal using the digital value in the processor being had to be compared with various threshold values.
