Abstract
Provided is a sensor lamp control method. When power is on, a sensor lamp senses ambient light intensity real time, if the ambient light intensity is lower than 100 Lux, the lamp is turned on and maintains lowest illumination, and the brightness of the lowest illumination is 10% to 20% of the complete-turning-on brightness of the lamp; when the presence of people or vehicles is sensed, the brightness of the lamp is raised to the complete-turning-on brightness, and when the people and the vehicles pass by, the brightness of the lamp is lowered to the lowest illumination and the lowest illumination is maintained; when the lamp is on and the presence of the people or the vehicles is sensed at the same time, the lamp is turned on in a two-stage manner, i.e., when the people and the vehicles pass by, the brightness of the lamp is lowered to the lowest illumination and the lowest illumination is maintained; and when the lamp maintains the lowest illumination, the lamp determines whether to carry out complete turning-off according to the real-time sensed ambient light intensity, if the ambient light intensity is equal to or more than 100 Lux, then the lowest illumination is cancelled and the lamp is completely turned off, and if the ambient light intensity is lower than 100 Lux, then the lamp maintains the lowest illumination, if the ambient light intensity is equal to or more than 100 Lux, then the lamp is not turned on. Compared to the prior art, the sensor lamp control method has the following advantages: it is not easy for people to encounter with such untoward effects as dazzling, or temporary blindness, or eye aches and the like, the energy consumption is relatively low, and the method can be used on occasions requiring certain illumination intensity to be ensured.
Description
Technical field
The invention belongs to lighting technical field, particularly relate to a kind of control method of sense light.
Background technology
At present, the control method of the sense light of prior art comprises that regularly keying, light sensation open and close, light sensation adds the infrared induction keying and light sensation adds the different control methods such as radar control keying, but some Code in Hazardous Special Locations need to guarantee certain intensity of illumination, sense light can not be closed fully, then the control method of the sense light of prior art is after closing, light fixture is no longer luminous closes fully, therefore can't satisfy the demand of these Code in Hazardous Special Locations; The control method of the sense light of prior art is when these Code in Hazardous Special Locations use simultaneously, light fixture is opened suddenly when induction, so that pedestrian's eyes meet with suddenly high light, and occur dazzling or the bad reactions such as temporary transient blinding or eyes stung, and then security incident easily occurs.
Summary of the invention
The present invention is directed to above problem a kind of control method that is difficult for causing the pedestrian the bad reaction such as dazzling or temporary transient blinding or eyes stung to occur and can guarantees at needs the employed sense light of particular field of certain intensity of illumination is provided.
The present invention overcomes the above problems used technical scheme: a kind of control method of sense light, after the energising, the real-time induced environment light intensity of light fixture is if environmental light intensity is less than 100Lux, then light fixture is opened, this moment, lamp brightness was kept minimal illumination, and the brightness of described minimal illumination is 10%～20% of light fixture standard-sized sheet brightness, when having sensed pedestrian or vehicle and pass through, lamp brightness is brought up to complete bright state, after pedestrian or vehicle passed through, lamp brightness was reduced to minimal illumination, and keeps; Sensed when if light fixture is opened pedestrian or vehicle by the time, then light fixture divides two-part to open, after pedestrian or vehicle passed through, lamp brightness was reduced to minimal illumination, and keeps; When light fixture was kept minimal illumination, light fixture judged whether to close fully according to real-time induced environment light intensity, if environmental light intensity more than or equal to 100Lux, then light fixture withdraws from minimal illumination and closes fully, if environmental light intensity less than 100Lux, then light fixture is kept minimal illumination; If environmental light intensity is more than or equal to 100Lux, then light fixture is not opened.
As preferably, described light fixture divides two-part to open to refer to that it is minimal illumination that light fixture is opened to first brightness, and maintains minimal illumination after 1～5 second, and lamp brightness rises to standard-sized sheet brightness again.
As preferably, described minimal illumination is 10%～15% of light fixture standard-sized sheet brightness.
As preferably, the adjusting of described lamp brightness is by PWM light modulation (pulse-width modulation (Pulse-Width Modulation) adopt adjust pulse duty factor reach the method for adjusting voltage, electric current, power).
As preferably, described light fixture closes to refer to be that light fixture extinguishes fully fully, though have pedestrian or vehicle by the time, light fixture is also no longer opened.
After adopting above method, compared with prior art, the present invention is because at environmental light intensity during less than or equal to 100Lux, light fixture is in the minimal illumination state, can be soon passer-by or vehicle this moment provides certain light to be used for judging the surface state that soon will pass through, and when pedestrian or vehicle enter into induction range, lamp brightness is brought up to complete bright state, then because maintain the minimal illumination state before the light fixture, therefore when light fixture is brought up to complete bright state, the people's of process eyes not can because of front and back brightness differ occur greatly dazzling, or temporary transient blinding, or the bad reaction such as eyes stung; Adopt simultaneously the light fixture of standard-sized sheet closed control method with respect to prior art, the present invention also can save 30%～40% power consumption, and the present invention also can use in needs guarantee the Code in Hazardous Special Locations of certain intensity of illumination; Moreover at environmental light intensity during less than or equal to 100Lux, when just having opened, just senses by light fixture pedestrian or vehicle through out-of-date, light fixture divides two-part to open, then can be so that the light intensity that receives before and after people's the eyes differ less, prevent that light fixture is complete bright and so that the bad reactions such as dazzling or temporary transient blinding or eyes stung appear in people's eyes suddenly.Therefore the present invention has and is difficult for causing the pedestrian to occur dazzling or the bad reactions such as temporary transient blinding or eyes stung, and energy consumption is relatively low and can guarantee at needs the employed characteristics of particular field of certain intensity of illumination.
