Description
Technical field
The utility model relates to light fixture detection field, specifically, relates to a kind of time monitoring statistical circuit.
Background technology
At present, monitor that in the durable or burn-in test of statistics light fixture, normal work total time is all make Current Transformer detect input current to realize substantially, but this method builds complexity, be easy to be interfered, if when curent change is few, correctly cannot judge the state of light fixture, when particularly having that in the light fixture of multiple light emitting source, a light emitting source does not work.Thus cause light fixture abnormal time, cumulative timer is also in timing.In addition, with reference to shown in Fig. 1, Fig. 2, market also has a kind of time monitoring statistical circuit, move and designed by portable class light fixture, move and portable class light fixture for single light source for charged pool, final what calculate is time of battery discharge.Be not suitable for multiple light courcess light fixture.And, but this circuit needs additional power source module and switch module, too increases cost undoubtedly.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of time monitoring statistical circuit, comprise, one cumulative timer, the two ends of described cumulative timer are connected with multiple photo resistance of connecting successively by wire, described photo resistance has light source receiving plane, and described in each, photo resistance is arranged with sleeve pipe except other positions of light source receiving plane.
Preferably, described sleeve pipe is glass fibre sleeve.
Further, photo resistance described in each and light source one_to_one corresponding to be measured.
Alternatively, at least two described photo resistance are with the mode of series connection and light source one_to_one corresponding to be measured.
Further, described cumulative timer is digital display cumulative timer.
Preferably, described cumulative timer includes alarm buzzer.
Compared with prior art, a kind of time monitoring statistical circuit described in the utility model, only with photo resistance, sleeve pipe, cumulative timer, structure is simple, with low cost, energy-conserving and environment-protective, stable performance, accurate timing, be specially adapted to multiple light courcess light fixture.

Embodiment
For making those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
With reference to shown in Fig. 3, a kind of time monitoring statistical circuit disclosed in the utility model embodiment, can for all lightings, it comprises, one cumulative timer 1, the two ends of described cumulative timer 1 are connected with multiple photo resistance 2 of connecting successively by wire, described photo resistance 2 has light source receiving plane, and other positions that photo resistance 2 removes light source receiving plane described in each are arranged with sleeve pipe (not shown).
Wherein, described cumulative timer 1 selects the H7ET-N of Omron, its internal battery, at least with 10 years, need not additionally can power, very energy-conservation.
Compare original time statistical circuit, the utility model eliminates middle power module, and switch module, provides cost savings greatly, and lacked the link that these are unnecessary, circuit is more stable.
Please refer to shown in Fig. 3, in this enforcement, in described figure, sample light fixture has four light sources 3 again, accordingly, adopts four photo resistance 2.Sleeve pipe is fiberglass pipe, solar heat protection and durable, after photo resistance puts sleeve pipe, only receives the light in dead ahead, the light source be not close to and the impact of room illumination, has and guides light and jamproof effect.During use by the photo resistance 2 of having overlapped sleeve pipe above receiving plane aim at the light source 3 of sample light fixture, sample has several light source just to use several photo resistance of overlapping sleeve pipe to aim at each light source respectively.In the present embodiment, a photo resistance correspondence is adopted to detect a light source, certainly, those skilled in the art are to be understood that, also multiple photo resistance correspondence can be adopted to detect a light source, or multiple light source is detected, and is not limited in any way at this by same photo resistance.
The mode that described photo resistance detects light source to be measured has two kinds, and wherein one is that each photo resistance correspondence detects a light source to be measured, or two and plural photo resistance detect a light source to be measured in the mode of series connection.
In technique scheme, described cumulative timer 1 is digital display cumulative timer, and described cumulative timer 1 inside is provided with alarm buzzer.After cumulative timer starts, start timing, when power-off or enabling signal disappearance, automatically preserve the last instant time, when next time starts, timing time in last time, clocking value added up.Window display timing time above described cumulative timer, described cumulative timer panel also has the operating state of the indicator light instruction cumulative timers such as power supply, timing, time-out, output, there is alarm buzzer inside, and buzzer siren is reported to the police when fault is freeed in photo resistance.Be that a cumulative timer is added up in the present embodiment, multiple cumulative timer in fact also can be adopted to carry out timing respectively.
In technique scheme, the application principle of photo resistance is as follows: when described photo resistance 2 is when being subject to illumination, as long as photon energy is greater than the energy gap of semi-conducting material, conduction band can be transitted to after the energy of the Electron absorption photon then in valence band, and the hole that generation one is positively charged in valence band, in this right semi-conducting material in electronics-hole produced by illumination, the number of charge carrier, makes its resistivity diminish, thus causes photo resistance resistance to decline.Illumination is stronger, and resistance is lower.After incident light disappears, the electronics-hole produced by photon excitation is to by compound, and the resistance of photo resistance also just recovers initial value.Add voltage at the metal electrode at photo resistance two ends, wherein just have electric current to pass through, when the light being subject to wavelength irradiates, electric current will with light intensity and become large, thus realize opto-electronic conversion.
When sample normal power-up light source complete bright time, each photo resistance 2 monitors the light of each light source respectively, and due to photoelectric effect, each photo resistance resistance value is substantially equal to 0, and cumulative timer 1 starts to calculate the time that light fixture normally works; When sample is abnormal, when having the light source of or more not work, due to photoelectric effect, thus just have the resistance of the photo resistance of or more to be tending towards infinitely great, cumulative timer 1 is held the clock.Can be facilitated by such design and know again the time that sample-light fixture normally works exactly.
Compare present traditional circuit, this circuit structure is simple, easy to use, no matter Financial cost, and cost of labor is saved all very much, and this circuit need not additionally be powered, and cumulative timer, from charged pool energy continuous operation more than 10 years, need not be safeguarded.The most important thing is relative traditional circuit, stability and accuracy all improve a lot.This circuit for be all lighting lamps, it is final that what calculate is normal lighting time of light fixture.Be particularly useful for multiple light courcess light fixture.
Above-mentioned explanation illustrate and describes some preferred embodiments of the present utility model, but as previously mentioned, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection range of the utility model claims.
