Abstract
A kind of control method of sense light, after energising, the real-time induced environment light intensity of light fixture, if environmental light intensity is less than 100Lux, light fixture is opened, now lamp brightness maintains minimal illumination, and the brightness of described minimal illumination is 10%～20% of light fixture standard-sized sheet brightness, in the time having sensed that pedestrian or vehicle pass through, lamp brightness is brought up to complete bright state, after pedestrian or vehicle pass through, lamp brightness is reduced to minimal illumination, and maintains; If light fixture sensed when opening pedestrian or vehicle by time, light fixture divides two-part to open, after pedestrian or vehicle pass through, lamp brightness is reduced to minimal illumination, and maintains; In the time that light fixture maintains minimal illumination, light fixture judges whether to close completely according to real-time induced environment light intensity, if environmental light intensity is more than or equal to 100Lux, light fixture exits minimal illumination and closes completely, if environmental light intensity is less than 100Lux, light fixture maintains minimal illumination; If environmental light intensity is more than or equal to 100Lux, light fixture is not opened; Compared with prior art, the present invention has and is difficult for causing pedestrian to occur the bad reactions such as dazzling or temporary transient blinding or eyes stung, and energy consumption is relatively low and can ensure the feature that the Code in Hazardous Special Locations of certain intensity of illumination uses at needs.
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 comprise timing open and close, light sensation open and close, light sensation add infrared induction open and close andLight sensation adds the different control methods such as radar control keying, but some Code in Hazardous Special Locations need to ensure certain intensity of illumination, and sense light can notClose completely, the control method of the sense light of prior art is after closing, and light fixture is no longer luminous closes completely, therefore cannot meetThe demand of these Code in Hazardous Special Locations; The control method of the sense light of prior art is in the time that these Code in Hazardous Special Locations use simultaneously, and light fixture is in senseSeasonable unlatching suddenly, makes pedestrian's eyes meet with suddenly high light, and occurs that dazzling or temporary transient blinding or eyes stung etc. are badReaction, and then easily there is security incident.
Summary of the invention
The present invention is directed to above problem provides one to be difficult for causing pedestrian to occur that dazzling or temporary transient blinding or eyes stung etc. are badReaction and can ensure the control method of sense light that the Code in Hazardous Special Locations of certain intensity of illumination uses at needs.
The present invention overcomes the above problems technical scheme used: a kind of control method of sense light, after energising, light fixture is felt in real timeAnswer environmental light intensity, if environmental light intensity is less than 100Lux, light fixture is opened, and now lamp brightness maintains minimal illumination, describedThe brightness of minimal illumination is 10%～20% of light fixture standard-sized sheet brightness, and in the time having sensed that pedestrian or vehicle pass through, lamp brightness improvesTo complete bright state, after pedestrian or vehicle pass through, lamp brightness is reduced to minimal illumination, and maintains; If when light fixture is openedSensed pedestrian or vehicle by time, light fixture divides two-part to open, after pedestrian or vehicle pass through, lamp brightness is reduced toMinimal illumination, and maintain; In the time that light fixture maintains minimal illumination, light fixture judges whether to close completely according to real-time induced environment light intensity,If environmental light intensity is more than or equal to 100Lux, light fixture exits minimal illumination and closes completely, if environmental light intensity is less than 100Lux,Light fixture maintains minimal illumination; If environmental light intensity is more than or equal to 100Lux, 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 first opened to brightness, and maintains minimumAfter illumination 1～5 second, 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 (PWM (Pulse-WidthModulation)Adopt adjustment pulse duty factor to reach the method for adjusting voltage, electric current, power).
As preferably, described light fixture closes to refer to be that light fixture extinguishes completely completely, though have pedestrian or vehicle by time, light fixtureAlso no longer open.
Adopt after above method, compared with prior art, the present invention is due in the time that environmental light intensity is less than or equal to 100Lux, light fixture placeIn minimal illumination state, now can be by passer-by or vehicle and provide certain light to be about to pass through for judgingSurface state, and in the time that pedestrian or vehicle enter into induction range, lamp brightness is brought up to complete bright state, because before light fixtureThe people's of process eyes maintain minimal illumination state, therefore in the time that light fixture is brought up to complete bright state, can not differ because of front and back brightnessThere is greatly the bad reactions such as dazzling or temporary transient blinding or eyes stung; Adopt standard-sized sheet full cut-off with respect to prior art simultaneouslyThe light fixture of formula control method, the present invention also can save 30%～40% power consumption, and the present invention also can ensure certain light at needsIn Code in Hazardous Special Locations according to intensity, use; Moreover in the time that environmental light intensity is less than or equal to 100Lux, when just having opened, light fixture just senses pedestrianOr vehicle is through out-of-date, light fixture divides two-part to open, and can make the light intensity receiving before and after people's eyes differ less, prevents light fixtureSuddenly complete bright and make people's eyes occur the bad reactions such as dazzling or temporary transient blinding or eyes stung. Therefore tool of the present inventionHave and be difficult for causing pedestrian to occur the bad reactions such as dazzling or temporary transient blinding or eyes stung, and energy consumption is relatively low and can beNeed to ensure the feature of the Code in Hazardous Special Locations use of certain intensity of illumination.
