Abstract
The utility model relates to an auxiliary light source with the timing function, which comprises a controller, an optical sensor and an LED, wherein the optical sensor is arranged nearby the LED and used for sensing the light emission of the LED and transmitting a corresponding sensing signal to the controller; the optical sensor is also connected with the controller; and the controller is used for timing the light emission of the LED.
Description
Technical field
The utility model relates to a kind of light source, particularly a kind of secondary light source that has clocking capability.
Background technology
Camera head such as video camera and camera needs to use secondary light source in order to obtain distinct image, and the photoflash lamp that we often use in camera is exactly wherein typical a kind of secondary light source.
Its secondary light source just used always after existing video camera was installed, and generally can not go to check when not having fault, had used fault always and just can be found.
Because limited as the LED lamp life-span of secondary light source, so the LED lamp failure can occur after using certain hour, the brightness deepening causes photographic effect unintelligible.Yet, often can't differentiate that the problem of video camera itself or LED lamp luminescent decay cause this moment, even therefore be that the LED lamp breaks down and also can directly whole video camera be returned manufactory usually and reprocess, cause the very big wasting of resources.
The utility model content
Cause the wasting of resources for solving existing secondary light source transmission fault, be necessary to provide a kind of secondary light source that can avoid the wasting of resources.
The secondary light source of the utility model band clocking capability, comprise controller, optical flame detector and LED, this optical flame detector is arranged near this LED, be used for the luminous of this LED of sensing and send corresponding sensing signal to this controller, this optical flame detector also connects this controller, and this controller is used for the fluorescent lifetime timing to this LED.
In the secondary light source of the utility model band clocking capability, this controller comprises a timer, when this LED is luminous, this optical flame detector sends one first sensing signal to this controller, the timer of this controller picks up counting, when this LED stops when luminous, this optical flame detector sends one second induced signal to this controller, and the timer of this controller stops timing.
In the secondary light source of the utility model band clocking capability, also comprise alarm, this alarm connects this controller.
In the secondary light source of the utility model band clocking capability, the timer of this controller preestablishes a standard value, when the timer accumulative total timing of this controller reached this standard value, this controller was exported an alarm signal to this alarm, and this alarm gives the alarm.
Compared to prior art, the secondary light source of the utility model band clocking capability can add up timing to the fluorescent lifetime of this LED, thereby can carry out alarm with reference to predefined standard value, only need this moment the related work personnel that this LED is changed, and do not need whole picture pick-up device depot repair, save cost greatly, saved resource.
Description of drawings
Fig. 1 is the block diagram of secondary light source one better embodiment of the utility model band clocking capability.
Embodiment
Below in conjunction with Figure of description the utility model execution mode is specified.
Seeing also Fig. 1, is the block diagram of secondary light source one better embodiment of the utility model band clocking capability.This secondary light source 10 comprises controller 11, optical flame detector 12, alarm 13 and LED14.This optical flame detector 12 is arranged near this LED14, is used for the luminous of this LED14 of sensing and sends corresponding sensing signal to this controller 11.This optical flame detector 12 also connects this controller 11, and this controller 11 connects this alarm 13.This controller 11 is used for the fluorescent lifetime timing to this LED14.This controller 11 comprises timer (figure does not show), and it can add up timing.
When this secondary light source operate as normal, when luminous, this optical flame detector 12 senses the light that this LED14 sends to this LED14 when this LED14 is luminous, and sends one first sensing signal to this controller 11 according to outer synchronous signal.At this moment, the timer of this controller 11 picks up counting.When this LED14 stops when luminous, the light that these optical flame detector 12 sensings send less than this LED14, this optical flame detector 12 send one second sensing signal to this controller 11, and this controller 11 stops the timing of this timer.
The timer of this controller 11 preestablishes a standard value, and the correspondence in useful life of this standard value and this LED14 for example can be set at 10000 hours.If the timer timing of this controller 11 accumulative total reaches this standard value, then represent this LED14 near the time limit in useful life, this moment, this controller 11 sent an alarm signal to this alarm 13, and this alarm 13 gives the alarm.
This secondary light source 10 also can comprise first light emitting source that is used for pointing out when this secondary light source 10 powers on, a secondary light source or that is used for pointing out when this LED14 is luminous is used for carrying out the 3rd light source of flash for prompting when the timer accumulative total timing of this controller 11 reaches standard value.Above-mentioned first～the 3rd light source can be the LED lamp.
Compared to prior art, the utility model secondary light source 10 can add up timing to the fluorescent lifetime of this LED14, thereby can carry out alarm with reference to predefined standard value, only need this moment the related work personnel that this LED14 is changed, and do not need whole picture pick-up device depot repair, save cost greatly, saved resource.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
