Fig. 3 is the novel intelligent led light source control program flow chart of the utility model environmental protection.
The specific embodiment
The novel intelligent led light source structural representation of environmental protection shown in Fig. 1, the light source front end adds diffusing globe 3, reduces dazzle greatly, the uniformity of very high whole lighting environment illumination makes whole lighting environment be in a comfortable luminous environment; In order to guarantee the LED luminous efficiency, heat radiation also is a key issue, and the light source of this illuminator adopts miniature pcb board 2; A slice PCB welds a LED; With heat-conducting glue 4 compact LED circuit and aluminium sheet 1 are fixed, utilized the characteristic of aluminium sheet 1 rapid heat dissipation, can solve heat dissipation problem preferably; With illuminance transducer and very color sensor MTCS-C2 the illumination and the colour temperature in underground store are monitored in real time, whole illuminator is in the self adaptation adjustment state of intelligence; Import the underground commercial center to sunshine, make full use of green energy resource, environmental protection and energy saving, LED replaces general light source, also is the major measure of green energy conservation.
Like the novel intelligent led light source control block diagram of Fig. 2 new green environment protection, the real-time monitoring of environmental illumination of illuminance transducer GZD-V1; Very color sensor MTSC-C2 monitors colour temperature in real time; Controller contrasts according to preset illumination, colour temperature and current illumination that monitors and colour temperature through the collection of digital collection device; Convert control signal to the DMX512 agreement through usb protocol after the contrast; Protocol controller output signal carries out negative-feedback control to driver to the LED of changes in temperature look, and specifically control procedure is referring to Fig. 3; Switching Power Supply 1 is the power supply of illuminance transducer GZD-V1 and digital collection device, and Switching Power Supply 2 is SP-240-30, for the work of LED provides stable voltage, plays the function of constant pressure source; LED group 1 ... LED group 6 is six groups of LED, and every group is 8 LED.Wherein 1,2,3 is warm colour, and 4,5,6 is cool colour; The DMX512 protocol controller is that LanBox-LCE DMX controller converts usb protocol to the DMX512 agreement, and DMX51; Protocol controller can be controlled 512 paths of LEDs simultaneously, so native system has high extensibility and soft property; Driver 1 and 2 is 3-Channel DMX512 Power LED Driver 350mA, to the DMX512 decoding, controls opening and closing of corresponding passage, is constant current 350mA with voltage transitions, realizes the efficient luminance of LED.
LED is controlled to be the DMX512 agreement, and with the electric current of the PWM of 160HZ control LED, the dutycycle of PWM is divided with numeral 0~255, and the luminous degree of LED is just determined by the digital quantity size.As the solar time, the daylight that imports in the basement is relatively more sufficient, LED luminescent decay then, and in the time of rainy day at cloudy day and evening, the luminous enhancing of LED.When detecting colour temperature when higher, reduce cold white light LEDs output, the output that improves warm white LED equilibrates to the colour temperature of requirement; When otherwise colour temperature is on the low side, improve the output of cold white light LEDs, reduce the output of warm white LED.
Operation labview program can be through guidance panel to the light source setup parameter, (the manually input of selected illumination (Flux) and colour temperature (CCT) input pattern; Preset mode 1,2,3; 4 with self-defined pattern) below specify manual input mode; Other patterns are exactly that illumination and colour temperature change by the mode of pre-setting, and setup gives true value in the time of change, is equivalent to repeatedly the combination of manual input mode.
Program execution flow such as Fig. 3 are following: CCT1 and flux1 are preset color temperature and illumination; CCT2 and flux2 are very color sensor actual measurement colour temperature and illumination photometer illuminations actually measured; C and W are the digital control amount of cool colour and warm colour LED, P be cool colour with the digital control amount of warm colour LED than (C/W).
1, illumination and colour temperature are all selected manual input mode, click the Setup button then at the illumination flux1 and the colour temperature CCT1. of Input Flux and Input CCT input requirement, activate new input.
2, inquire about the ratio of cold white light LEDs and warm white LED: P=C/W according to colour temperature; Inquire the digital quantity W=C=NO that should export according to illumination.If W*P>C, W=C/P then, otherwise W=NO.
3, mobilize W and C to led controller respectively, read the color temperature value CCT2 of MTCS-C2, the value flux2 of illuminance transducer.
4, if flux1-flux2>flux1*5%, W=W+1 then, C=W*P, execution in step 6.< flux1*5%, W=W-1 then, C=W*P, execution in step 6 if flux1-flux2.
5, if CCT1-CCT2>150K, W=W-1 then, C=C+1, execution in step 6; < 150K, W=W+1 then, C=C-1, execution in step 6 if CCT1-CCT2.
6, if W>255 or C>255, W=255 or C=255 then; If | < ≤150K then exports=flux1*5%&&|CCT1-CCT2| flux1-flux2|: Find the requirement.
7, if setup and stop are false, execution in step 2. is vacation if setup is true stop, execution in step 1, if stop is true, and shut down procedure.
