Description
Technical field
The utility model relates to the LED lighting technical field, especially relates to the LED lighting device of a kind of writing task time.
Background technology
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 is very long, but, owing to not having practicable accelerated ageing test method to verify its life-span, generally adopts aging 6000 hours of routine or longer time to judge its life-span at present.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 to LED manufacturing enterprise.For the user, unless the product short term failure, otherwise also owing to can not accurately grasping the running time of illuminating product, and be difficult to the life-span of illuminating product is verified, its lawful right may be damaged.For example, product nominal 20000 hours, as fruit product to 10000 hour had lost efficacy, 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 utility model, for above-mentioned the deficiencies in the prior art, provides the LED lighting device of a kind of writing task time, can grasp in time the service life of LED lighting apparatus.
The technical scheme the utility model proposes is as follows:
The LED lighting device of a kind of writing task time, comprise substrate, lampshade, optical sensor, timer, display screen, AD-DC power supply changeover device, rectification circuit and at least one LED light source; Described timer is connected to described AD-DC power supply changeover device, optical sensor and display screen; The external 220V AC power of described rectification circuit, inside connect described AD-DC power supply changeover device; Described optical sensor and at least one LED light source are fixed on described substrate, and are positioned at the spatial accommodation of described substrate and lampshade formation.
Preferably, be provided with outer cover on described optical sensor.
Preferably, the lampshade inboard directly over described optical sensor is provided with an anti-dazzling screen.
The beneficial effects of the utility model are: added timer in the LED lighting device, with the working time of real time record LED lighting device, and shown; Simultaneously, also in luminous zone, added the optical sensor that obtains illumination data, to measure in real time brightness value, until the brightness value recorded is during lower than preset value, now the working time of LED lighting device record is the life-span of this LED lighting device, thereby feature true lifetime that reflects exactly the LED lighting device, provide accurate information for solving in various business models to efficient illuminating product life appraisals such as LED.
The accompanying drawing explanation
Fig. 1 is the structure chart of the LED lighting device of writing task time of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
The LED lighting device of writing task time as shown in Figure 1, its upper end is provided with substrate 1 and lampshade 2, is fixed with at least one LED light source 3 on substrate 1, is provided with timer 4 and the AD-DC power supply changeover device 6 for powering in described LED lighting device.As shown in Figure 1, the 220V AC power is input to rectification circuit 5 and carries out rectification, then exports AD-DC power supply changeover device 6 to and is changed, thereby provide the low voltage DC power supply for timer 4; Timer 4 connects display screen 7, and described display screen 7 is for being arranged on the LCD display on LED lighting device side; Also be provided with optical sensor 8 in the luminous zone of described LED lighting device, for obtaining the brightness value of LED light source, described optical sensor 8 is connected to timer 4, and optical sensor 8 is real-time transmitted to timer 4 by described brightness value, when brightness value, during lower than preset value, timer 4 quits work.Described optical sensor 8 and LED light source 3 are fixed on described substrate, and are positioned at the spatial accommodation of described substrate and lampshade formation.Described optical sensor 8 is arranged on the center of substrate 1.Be provided with outer cover 9 on described optical sensor 8.Lampshade inboard directly over optical sensor 8 is provided with an anti-dazzling screen 10.
When power supply is switched on, the LED lighting device starts illumination, and timer is started working, and in time by time showing on display screen, timer has the on-the-spot time function of power-off protection, after guaranteeing power interruptions, the time can be remembered, and waits energising next time to continue to start timing; Until the brightness value that optical sensor 8 transmits is during lower than preset value, timer quits work, and the time on display screen of now being presented at is the life-span of this LED lighting device.
Finally it should be noted that above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment, the utility model is had been described in detail; those of ordinary skill in the field are to be understood that; still can modify or the part technical characterictic is equal to and replaces and do not break away from the spirit of technical solutions of the utility model the specific embodiment of the present utility model, it all should be contained in the middle of the technical scheme scope that the utility model asks for protection.
