Detailed description of the invention
In order to make content of the present invention clearly with understandable, below in conjunction with specific embodiments and the drawings, content of the present invention is described in detail.
< first embodiment >
Fig. 1 schematically shows the block diagram of LEDy street lamp device according to a first embodiment of the present invention.
As shown in Figure 1, LEDy street lamp device according to a first embodiment of the present invention comprises: lampshade (not shown), the first LED group LED1, the second LED group LED2, LED group driving control unit DR and controller CR.
Preferably, the first LED group LED1 and the second LED group LED2 is contained in single lampshade.Alternatively, the first LED group LED1 and the second LED group LED2 is contained in two lampshades separately.
Wherein, when starting described LEDy street lamp device and starting working, controller CR sends the first command signal S1 to LED group driving control unit DR.LED group driving control unit DR drives a job in the first LED group LED1 and the second LED group LED2 according to the first command signal S1, and another making in the first LED group LED1 and the second LED group LED2 does not work.
When starting described LEDy street lamp device and starting working, LED group driving control unit DR drives the first LED group LED1 to work (luminescence) according to the first command signal S1, thus transmitting the first light L1 throws light on, and the second LED group LED2 is made not work (not luminous).Alternatively, such as, when starting described LEDy street lamp device and starting working, LED group driving control unit DR drives the second LED group LED2 to work (luminescence) according to the first command signal S1, thus transmitting the second light L2 throws light on, and the first LED group LED1 is made not work (not luminous).
Further, controller CR sends the second command signal S2 to LED group driving control unit DR after described LEDy street lamp device is started working after very first time interval.LED group driving control unit DR drives the first LED group LED1 and the second LED group LED2 both to work (luminous) according to the second command signal S2.Thus the first LED group LED1 and the second LED group LED2 launches the first light L1 respectively and the second light L2 throws light on.
Further, controller CR sends the 3rd command signal S3 to LED group driving control unit DR after described LEDy street lamp device is started working after second time interval; Wherein second time interval was longer than very first time interval.LED group driving control unit DR drives a job in the first LED group LED1 and the second LED group LED2 according to the 3rd command signal S3, and another making in the first LED group LED1 and the second LED group LED2 does not work.
Such as, after described LEDy street lamp device is started working after second time interval, LED group driving control unit DR drives the first LED group LED1 to work (luminescence) according to the 3rd command signal S3 thus launches the first light L1 and throws light on, and makes the second LED group LED2 not work (not luminous).Alternatively, such as, LED group driving control unit DR drives the second LED group LED2 to work (luminescence) according to the 3rd command signal S3 thus launches the second light L2 and throws light on, and makes the first LED group LED1 not work (not luminous).
Preferably, controller CR can arrange the concrete duration in very first time interval and second time interval.
More particularly, such as, in possibility every day about 19 in summer and meeting winter about 17 darkness, street lamp work can be started thus in some every day 19 (summer) or 17 points (winter) left and right, at this moment because sky is not black especially, can only require that a job in two groups of LED groups can illuminate road surface.After this, such as about 21 (very first time is spaced apart 2 hours or 4 hours) because it is very black, so make two groups of LED street lamp all work road surface of throwing light on.After this, such as about 5 (summers in the morning, now second time interval was 10 hours) or 7 points (in winter, now second time interval was 14 hours) sky, left and right slightly bright, therefore only need again one group of LED group to illuminate road surface.
According to a first embodiment of the present invention, provide a kind of can the LEDy street lamp device of effective use of energy sources.
Further preferably, when starting described LEDy street lamp device and starting working and after described LEDy street lamp device is started working after second time interval, start different LED group work respectively, thus make the loss of two groups of LED groups synchronous.
< second embodiment >
Fig. 2 schematically shows the block diagram of LEDy street lamp device according to a second embodiment of the present invention.
As shown in Figure 2, except comprising lampshade, the first LED group LED1, the second LED group LED2, LED group driving control unit DR and controller CR, the LEDy street lamp device of second embodiment of the invention also comprises the first optical sensor T1 be arranged in the first LED group LED1 and the second optical sensor T2 be arranged in the second LED group LED2.
Wherein, the first optical sensor T1 can sense the luminous situation in the first LED group LED1, and feeds back the first feedback signal F1 when sensing the first LED group LED1 luminescence to LED group driving control unit DR (or controller CR).
Equally, the second optical sensor T2 can sense the luminous situation in the second LED group LED2, and feeds back the second feedback signal F2 when sensing the second LED group LED2 luminescence to LED group driving control unit DR (or controller CR).
According to the first feedback signal F1 received and the second feedback signal F2, LED group driving control unit DR (or controller CR) judges that whether the first LED group LED1 and the second LED group LED2 is working properly respectively.
Thus, new LED group can be replaced in time when the first LED group LED1 and the second LED group LED2 breaks down, thus carry out effective road lighting.
According to a second embodiment of the present invention, a kind of LEDy street lamp device that automatically can detect LED and whether damage is provided.
Although to explain principle of the present invention as the situation of street lamp, art technology ordinary person be understandable that, above-mentioned LEDy street lamp device obviously can be applied in other concrete illumination application.
