Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model lamp life timer.
Embodiment
Below in conjunction with accompanying drawing the utility model is further set forth.
As shown in Figure 1, lamp life timer of the present utility model comprises time memory cell, time display unit, timing processing unit, time indicating member, mode selecting unit and power supply indicating member.
1, time memory cell
Time memory cell is used to store the service time of light fixture accumulation when cutting off the power supply each time, it is by the most handy EEPROM of storer U1() be core, resistance R 4 and R5 are pull-up resistor, U1, R4 and R5 form memory circuit, when being used to store each outage, the light fixture accumulated time temporal information that the timing processing unit sends.
2, time display unit
Time display unit is used to show light fixture accumulation service time, service time and this time of light fixture two parts service time of the light fixture accumulation of time cell stores when light fixture information service time that described time display unit shows comprises last the outage, be sum of the two the service time altogether of light fixture.General adopt liquid crystal display, receive the SPI signal of timing processing unit as LCD after, show current information of time, show that least unit is minute.
3, timing processing unit
The timing processing unit is used for accessing the service time of the light fixture accumulation of time cell stores when once cutting off the power supply at every turn when powering on, and this time service time of timing light fixture; When cutting off the power supply next time, the service time of the light fixture that accesses accumulation and the service time of this time light fixture are accumulated in together, update stored in the time memory cell, the timing processing unit is simultaneously also with information service time of control time display unit output light fixture.The timing processing unit is made up of central processing unit U2 and clock circuit (2Hz), the 7th pin of U2 and the 8th pin tie-time indicating member, the the 9th and the 10th pin tie-time storage unit, the 11st pin connection mode selected cell, the 13rd pin and clock circuit makeup time benchmark, it is current when the service time of time light fixture to be used for timing, and the 14th pin is exported one group of SPI shows signal and used for time display unit as showing.
4, time indicating member
Because be certain the entire life of dispatching from the factory of each light fixture, life-span such as electricity-saving lamp is about 8000 hours, approximately be 12000 hours the serviceable life of HID gas-discharge lamp, the life-span of LED and electrodeless lamp approximately is 100000 hours, the utility model can be divided into the serviceable life of light fixture some five equilibriums, represent the different usage time interval of light fixture by the order of lighting of different pilot lamp then, the different usage time interval of representing light fixture that can also show different colors by same pilot lamp can also be by the different usage time interval of lighting the order color-set incompatible indication lamp tool different with each pilot lamp demonstration of different pilot lamp.Such as electricity-saving lamp can be divided into 2 equal portions in 8000 hours (if precision prescribed is higher, can more equal portions), like this can be by two pilot lamp D2 and D3 such as () LED and current-limiting resistance R2 and R3 composition, when timing processing unit control D2 lights, the service time of expression light fixture was at 0 ~ 3999 hour, when timing processing unit control D3 lights, the service time of expression light fixture was at 4000 ~ 7999 hours, when near 8000 hours, can extinguish by timing processing unit control D2 and D3, perhaps alternate manner is reminded and to be used for this light fixture and to have arrived serviceable life, can change light fixture!
5, mode selecting unit
Because the serviceable life of every kind of light fixture is different, so the time of each time period of light fixture is different, the utility model can be realized the different light fixture of lamp life timer control by mode selecting unit, and mode selecting unit can adopt the wire jumper slide switch to realize.Detailed process is:
1) electricity-saving lamp pattern: when K1 selects ON, when K2 selects OFF, pick up counting from 0 during the bright lamp of light fixture, amount to 8000 hours, the D2 green indicating lamp was lighted from 0 hour to 3999 hours, and the expression bulb normally uses; When bulb during from 4000 hours to 8000 hours, D2 and D3 light, and show yellowly, and at this moment light fixture is still normal, begins to warn this lamp life and has arrived half; In the time of 8000 hours, D2 extinguishes, and D3 continues to light, and please more changes the bulb.
2) HID gas-discharge lamp pattern when K1 selects OFF, when K2 selects ON, picks up counting from 0 during the bright lamp of light fixture, the longest timing 12000 hours, and the D2 green from 0 hour to 5999 hours, the expression bulb normally uses; When bulb during from 6000 hours to 12000 hours, D2 and D3 light, and at this moment bulb is still normal, begins to warn this bulb life and has arrived half; In the time of 12000 hours, D2 extinguishes, and D3 continues to light, and points out this bulb life to arrive, and please more changes the bulb.
3) LED and electrodeless lamp pattern, when K1 selects OFF, when K2 selects OFF, pick up counting from 0 during the bright lamp of light fixture, the longest timing 100000 hours, from 0 hour to 49999 hours, the D2 green, the expression bulb normally uses, when bulb during from 50000 hours to 99999 hours, D2 and D3 light, and at this moment bulb is still normal, begin to warn this bulb life and have arrived half; In the time of 100000 hours, D2 extinguishes, and D3 continues to light, and points out this bulb life to arrive, and please more changes the bulb.
After more changing the bulb K1, K2 are pushed OFF under the situation of energising, in 5 seconds K1, K2 are pushed ON simultaneously, at this time outage, the type of selected light fixture is dialled back in the back that more changes the bulb, and light fixture will continue to pick up counting from 0 hour.
6, power supply indicating member
The power supply indicating member is used to show whether the timing processing unit powers normally, and it is formed by D1 such as current resistor R1 and LED, is in which stage the service time of color tips light fixture that in addition can also be by D2 and D3 lamp.
The above only is a better embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, in implementation process, may there be local small structural modification, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, and belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
