In recent years, along with the development of novel energy-conserving illuminating product technology, LED illuminating product particularly, not only light efficiency is high, and the life-span is also very long.Compare incandescent lamp, light efficiency improves 5-10 doubly, and the life-span is improved 30-50 doubly.So obtain businessman and user's approval for the reducing energy consumption of various traditional lightings, particularly EMC(energy contract management) pattern, receive especially increasing concern.
The theoretical life-span of the novel energy-saving illuminating products such as LED (annotate: the luminous flux attenuation that life of product refers to product the service time to 70% time) is very long, but owing to not having practicable accelerated ageing test method to verify its life-span, generally adopted conventional aging 6000 hours at present or the logical maintenance rate of light of longer time judges its life-span.Because the technical development of the novel energy-savings such as LED illumination is very fast, often a product has just obtained or has not obtained sufficient life-span checking, and its technology perhaps falls behind.So cause the dual waste of time and money for LED manufacturing enterprise.For the user, unless the product short term failure, otherwise also owing to can not accurately grasp the running time of illuminating product, and be difficult to the life-span of illuminating product is verified, its lawful right may be damaged.Such as a product nominal 25000 hours, hour to have lost efficacy as fruit product to 20000, the user is difficult to put to the proof or right-safeguarding.
So the life appraisal of the novel energy-saving illuminating products such as LED and checking are a puzzlement manufacturer and user's important difficult problems.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, is provided a kind of service time that can in time grasp product, embody the LED lighting device in the life-span of product.
Technical scheme of the present invention is achieved in that
A kind of LED lighting device is provided with the controller that has both clocking capability and the low voltage DC power supply that is used for power supply in the LED lighting device, controller is connected with display terminal.

As preferably, controller is to connect display terminal by direct mode.
As preferably, controller directly connects display terminal and refers to: terminal is on the LED lighting device, and controller is with the data record that obtains or be presented on display terminal.Described display terminal is LCD display.
In order further to measure more accurately the life-span of LED, as preferably, also be provided with optical sensor in the luminous zone of LED lighting device, described optical sensor connects controller, and controller obtains illumination and converts luminous flux, lux maintenance record to or be sent to display terminal.
Install for convenient, as preferably, described optical sensor is arranged on the substrate of fixed L ED light source.
In order better to obtain illumination data, as preferably, described optical sensor is arranged on the substrate center position.
For fear of the impact of possible external high light, as preferably, be provided with cup outside optical sensor.
In order to guarantee that optical sensor receives only the illumination of lamp interior, guarantee the accuracy of data, as preferably, be provided with an anti-dazzling screen on the lampshade of the LED lighting device above optical sensor.
As preferably, the built-in timing circuit of described controller or timing program.Thus, the standby clocking capability of controling appliance.
Adopted design philosophy of the present invention and the beneficial effect of technique scheme to be:
The present invention has added the controller that clocking capability is arranged in the LED lighting device, with the operating time of real time record LED lighting device, and be transferred to display terminal and show; Simultaneously, also added the optical sensor that obtains illumination data in the luminous zone, with real-time measurement lux maintenance, until the lux maintenance that records is lower than default critical life-span during lux maintenance numerical value, the operating time of LED lighting device record this moment is life-span of this LED lighting device.
The present invention can record operating time of LED lighting device and corresponding light is logical keeps, feature true lifetime that can reflect exactly the efficient long-life illuminating products such as LED lighting device provides accurate information for solving in various business models to efficient illuminating product life appraisals such as LED.

Fig. 2 is the structural representation of the another kind of supply power mode of MCU controller in embodiment;
Fig. 3 is the circuit control principle drawing of each module of LED lighting device in embodiment.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of LED lighting device, as shown in Figure 1, be provided with substrate 1 and lampshade 2 in LED lighting device upper end, be fixed with a plurality of LED light sources 3 on substrate 1, be provided with controller 4 and be used for the low voltage DC power supply 6 of power supply in the LED lighting device.Described controller 4 is the MCU controller.As Fig. 1, shown in Figure 3, low voltage DC power supply 6 connects controllers 4, and controller 4 directly connects display terminal 7, and described display terminal 7 is the LCD display that is arranged on LED lighting device side.
Also be provided with optical sensor 8 in the luminous zone of LED lighting device, described optical sensor 8 connects controller 4, and controller 4 obtains illumination and converts lux maintenance to and is sent to display terminal 7.Described optical sensor 8 is arranged on substrate 1 center.Be provided with cup 9 outside optical sensor 8.Be provided with an anti-dazzling screen 10 on the lampshade above optical sensor 8.
Because controller 4 modules need the input of low voltage DC power supply, generally the LED driving power can be exported low voltage DC, so can directly power to controller by low voltage DC power supply 6; If the driving power mode of other types, as shown in Figure 2, need that the AC-DC module is arranged, the DC-C module carries out voltage transitions.
When the power supply energising, the LED lighting device begins illumination, and the clocking capability of MCU controller also begins timework simultaneously, and in time be presented on display terminal, the controller timing has the on-the-spot time function of power-off protection, after guaranteeing power interruptions, time can be remembered, and waits energising next time to continue the beginning timing; Until when the LED lighting device can not be lighted, the time that show this moment was the life-span of this LED lighting device.
Further, the LED lighting device start working for the first time and preheating after 30 minutes optical sensor read number one time, and then read one time number every 30 minutes, and read continuously 3 times, the reading of back and the number of degrees are for the first time compared, if rate of change is in 10%, controller is averaged and is set as the illumination initial value, and simultaneously, illumination data is transferred to the MCU controller, again, read number per half an hour one time, and optical sensor can not descend to the illumination of dump moment and makes a response simultaneously.Controller is compared according to brightness value and illumination initial value that plug-in will read in real time, be converted to luminous flux, lux maintenance sends to display terminal and shows, when the lux maintenance that records lower than default critical life-span during lux maintenance numerical value, the operating time that this moment, the LED lighting device recorded is the life-span of this LED lamp, critical life-span lux maintenance can be according to the actual conditions Set arbitrarily, such as being traditionally arranged to be 70%.
