The specific embodiment
Below, be applicable to for the lighting apparatus that the present invention is relevant at length to describe the embodiment of street lamp with reference to accompanying drawing.But, can be suitable for the lighting apparatus of technological thought of the present invention, be not limited to the street lamp, for example, in the lighting apparatus that uses in the outdoor lightings such as road lighting all is included in.
A is as shown in Figure 1 for the lighting apparatus of this embodiment (street lamp), possesses the 1st light source the 1, the 2nd light source the 2, the 1st power supply unit the 3, the 2nd power supply unit 4, illuminance transducer 5, timing portion 6, control part 7.The 2nd light source 2 is formed by radiating all the time in street lighting the Light-Emitting Diode of the light of normally used color temperature (about 5000K).On the other hand, the 1st light source 1 is made up of the Light-Emitting Diode of the light of the also high color temperature of the color temperature of emission ratio the 2nd light source 2 (for example, about 8000K).
The the 1st and the 2nd power supply unit 3,4 all is made up of the variable Switching Power Supply of output voltage (for example, buck circuit).Illuminance transducer 5 for example possesses solar cell, and the output voltage of the solar cell that will change relatively corresponding to lightness on every side outputs to control part 7 as detecting voltage.Timing portion 6 for example utilizes the oscillator that has used quartz crystal to come present moment is carried out timing.Control part 7 as the main composition key element, is stored in program in memory through the microcomputer execution with microcomputer, thus the control action of stating after carrying out.
Fig. 2 shows the outside drawing of the lighting apparatus A of this embodiment, and lighting apparatus A is made up of lamp body 100 and pillar 110.Pillar 110 is made up of the metallic object of column, and the bottom is embedded in the ground.Lamp body 100 is installed in upper end at pillar 110.Lamp body 100 forms the elongated case shape of lower surface opening.And as shown in Figure 3, in the inboard of lamp body 100, a plurality of Light-Emitting Diodes of the 1st and the 2nd light source 1,2 are configured in that to reach the left and right sides up and down adjacent.And, though not shown, on lamp body 100, be provided with reflecting part material, diffusion part material.Mix and shine the road surface equably from two kinds of light appropriateness of the 1st and the 2nd light source 1,2 radiation.
Here, in order not detect, and illuminance transducer 5 is arranged on the top, top (with reference to Fig. 2) of lamp body 100 from the light (artificial light) of the 1st and the 2nd light source 12 radiation.
Secondly, with reference to the time diagram of Fig. 4, the control action of control part 7 is described.And the transverse axis among Fig. 4 representes that the longitudinal axis is represented the light quantity of the 1st and the 2nd light source 1,2 respectively constantly.
Through illuminance transducer portion 5 detected ambient illuminances during more than or equal to the threshold value of regulation, control part 7 makes the 1st and the 2nd light source 1,2 all for the light-off state.And, when the sun tilts near at sunset, through illuminance transducer 5 detected ambient illuminances than above-mentioned threshold value low (moment t=t1 of Fig. 4).Ambient illuminance is during less than threshold value, and control part 7 makes the 2nd light source 2 specified lighting a lamp, and makes lingeringly specified the lighting a lamp of the 1st light source 1 to the 2 light source 2 (moment t=t2 of Fig. 4).Here, along with descending (along with advancing of moment t) through illuminance transducer portion 5 detected ambient illuminances, control part 7 increases the light quantity of the 1st light source 1 gradually.And, in Fig. 4, representing the light quantity of the 2nd light source 2 with solid line M, with dashed lines N representes the light quantity of the 1st light source 1.
And when the sun began to tilt, control part 7 made low the 2nd light source 2 specified the lighting a lamp of color temperature, and this can give the sense of security with psychology, and prevented the obstruction of view.In addition, (t1～t2), control part 7 increases slowly through the light quantity that makes the 1st high relatively light source 1 of color temperature and improves visibility constantly during till falling fully to the sun.Then, after the sun fell fully, control part 7 made the 1st and the 2nd light source 1,2 all specified lighting a lamp, thereby guarantees visibility, and gave the sense of security with psychology.
In other words, during the environment deepening, light a lamp, come efficiently to guarantee pedestrian's visibility through make the high luminance relay light source temperature (the 1st light source 1) that comprises short wavelength's composition morely.Simultaneously,, pedestrian's uneasy psychology is alleviated if low color temperature light source (the 2nd light source 2) is lit a lamp, and, reduce through making color temperature, can suppress the deterioration of view.In addition, system of Himdu logic brightness reduces, and visual acuity is to shorter wavelength shift, and therefore, deepening gradually in the process of sunset makes short wavelength's composition of illumination light increase relatively thereupon, thereby can improve visibility effectively.Increasing relatively gradually of this short wavelength's composition is that the control of the high luminance relay light source temperature (the 1st light source 1) through often comprising short wavelength's composition obtains.On the other hand, low color temperature light source (the 2nd light source 2) suppresses the color temperature step-down and works when guaranteeing pedestrian's the sense of security and desirable view in the lightness of guaranteeing environment.Therefore, hang down color temperature light source (the 2nd light source 2) and moment interlock through making, and the 2nd light source 2 is only lit a lamp the pedestrian for a long time, pedestrian's the sense of security and desirable view can easily be provided.
In this form of implementation, if surpassed the moment t=t3 (for example 2:00 AM) in the late into the night through the current time of timing portion 6 timing, then control part 7 is turned off the light the 2nd light source 2, only makes the 1st light source 1 specified lighting a lamp (with reference to Fig. 4).Thus, guarantee visibility through making the 1st light source 1 specified lighting a lamp, and, seek energy-conservation through making 2 light-offs of the 2nd light source.That is, because few time period of traffic volume at dead of night, the uneasy sense of pedestrian's psychology and reduce about the importance degree of view, institute is so that the output reduction of low color temperature light source (the 2nd light source 2), thereby can seek energy-conservation.Though the lightness in space reduces, the peak value of visual acuity squints to short wavelength's direction greatly, therefore, throws light on through using the high luminance relay light source temperature (the 1st light source 1) that often comprises short wavelength's composition, can guarantee visibility effectively.This embodiment, if the current time through 6 timing of timing portion surpasses the moment in the late into the night, then control part 7 is turned off the light the 2nd light source 2, but for example also can make the light quantity of the 2nd light source 2 reduce to the lower limit of regulation.
Early morning on next day; The sun begins to rise, and when beginning to rise through illuminance transducer portion 5 detected ambient illuminances, control part 7 reduces the light quantity of the 1st light source 1 gradually; Become more than or equal to the time point (t=t4 constantly) of threshold value at above-mentioned ambient illuminance, the 1st light source 1 is turned off the light.
But, when control part 7 changes the light quantity of the 1st light source 1, need not be along with increasing constantly and gradually or reducing gradually.For example, also can be as shown in Figure 5, at the moment t=t2 that the sun falls fully; Control part 7 makes that the 1st light source 1 is specified quickly lights a lamp; And when through illuminance transducer 5 detected above-mentioned ambient illuminances during more than or equal to the time point of threshold value (t=t4 constantly), the 1st light source 1 is turned off the light quickly.
