Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, 2, the LED illuminating lamp of adjustable color temperature of the present utility model comprises white LED lamp 1, the white light drive circuit 2 corresponding with described white LED lamp, orange light LED lamp 3, the orange light drive circuit 4 corresponding with described orange light LED lamp, and environment monitoring sensor 5, described environment monitoring sensor can detect external environment condition and environmental information is sent to control part 6 and control white LED lamp and/or orange light LED lamp is opened or closed.Wherein, described white LED lamp arranges between two parties, and described orange light LED is arranged on around white LED lamp.Described environmental sensor comprises that the brightness that can detect sky white light is with the luminance sensor 7 as judgement difference day and night, simultaneously, this luminance sensor also provides one group of basis comparative voltage, and the magnitude of voltage that other transducers obtain can carry out environment judgement with comparing of this basis comparative voltage; In can testing environment, vapour concentration to be to determine whether the moisture sensor 8 in greasy weather, and in can testing environment particle concentration to determine whether the haze transducer 9 in haze sky.Each described transducer can also be arranged on lampshade, can be also independently a sensor unit case, then be connected with control cabinet by cable.Certainly, also the different setting positions of adjusting arbitrarily white LED lamps and orange light LED lamp of visual service condition, as placed in the middle in orange light LED, or both lamps that are crisscross arranged.Wherein, it should be noted that, luminance sensor is mainly for distinguishing night or daytime, described basic comparative voltage also can be by presetting or utilize a pair of basic infrared sensor to measure, and utilizes a pair of infrared sensor not affected by environment to provide judgment standard for each infrared sensor.

Specifically, described moisture sensor is infrared sensor, it comprises infrared emitting end and receiving terminal, is provided with convex lens to improve detection range in described receiver the place ahead, and described receiving terminal relatively draws vapour concentration according to what receive photosignal intensity and benchmark comparative voltage.

Described haze transducer is a plurality of infrared sensors, each infrared sensor comprises reflector and receiver, described a plurality of reflectors evenly arrange in one plane, and described a plurality of receivers are arranged on another plane opposing with described plane accordingly.The layout on a face of a plurality of reflectors can adopt endian format or matrix form layout, when judging, can allow a reflector produce pulse, all receivers all simultaneously or the mode receiving one by one test, test specification is large like this, can effectively improve the precision of test, simultaneously, for improving precision, corresponding each reflector of each receiver can be set a voltage comparison value, the voltage of the light signal generating at every turn receiving is compared with corresponding voltage comparison value, by comparing corresponding voltage comparison value, can judge test result this time, can improve data volume like this, improve analysis ability.

Further, also can comprise another group infrared sensor, it is perpendicular that the reflector of two sensors arranges plane, that is to say, be relatively forward X-axis sensing, and another group is Y-axis transducer, two sensors is identical circuit theory, but the two formation is space crossed, creates a cube three dimensions, can successfully judge the particle concentration in this space like this.Two groups of infrared sensors are space matrix Boulez, and each described infrared sensor cross scan also receives impulse wave quantity or intensity is carried out particle concentration judgement.Certainly, also can adopt the multiple stereoscopic arrangement forms such as sphere formula.

Because produce the phenomenon of haze, be not single one physical phenomenon, but two kinds of different molecular mixing form, fog is to be formed by aqueous vapor, but still has light transmission, even sometimes has the sea market aerial mirage in building of stinging, and is exactly mirror phenomenon.Haze is that PM2.5 particle forms light tight phenomenon, and principal character is light tight, and the luminous intensity in environment can decline to a great extent, so general street lamp can produce, is mistaken for night.Therefore to be divided into two kinds of different transducers, could distinguish and judge.And for the particle content of air, form the particle concentration analysis in the short space of X-axis and Y-axis three-dimensional.The intersection that these two groups of transducers are two arrays scans, and when example concentration is zero, the number of pulses that can receive or intensity are maximum, when the concentration of particle is low, the black mole masking amount of array is less, and institute's impulse wave that is blocked is few, and number of pulses or the intensity that can receive are large.Particle concentration is higher, and the black mole of generation covers pulse wave number the more, and number of pulses or the intensity that can receive are little, the collection by each point data gather can analyze environmental aspect then corresponding white light or/or the orange light LED light source of driving light or close.

The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
