Control module 30 comprises a control panel 33; This control panel 33 can be through 10 inputs of regulation and control unit and the parameter that is provided with; And the ambient light parameter of the aquarium gathered of photosensitive unit 40 is adjusted the electric current output of power subsystem 70; Thereby reach automatic color matching and adjustment brightness, thereby the effect that simulated solar irradiation changes.
Lighting unit 60 comprises four LED fluorescent tube modules; Form by two white LED lamps 61,62 (colour temperature 12000K-20000K) and two blue LED lamps (wavelength 420nm-480nm) 63,64 respectively; The LED fluorescent tube module can be by a plurality of low power LED lamp pearls (like SMD3528 lamp pearl; SMD5050 lamp pearl) or powerful 1W; The lamp pearl of 3W or bigger power and brightness forms above being installed in the aluminium of heat radiation, and lighting unit 60 is according to the luminous intensity of the output current adjusting LED lamp of power subsystem 70.Lighting unit 60 also can make up for other the LED lighting module more than two groups; Such as two groups of white lights, three groups of led module combinations or two groups of blue lights of one group of blue light, three groups of led module combinations of one group of white light are R (redness) perhaps; G (green), three groups of led module combinations of B (blueness) etc.
Power subsystem 70 is constant-current supplies of scalable electric current output; The power subsystem 70 of the embodiment of the invention comprises constant voltage source module 71 and constant-current supply module 72; Power subsystem 70 also can be that the electric current distribution module adds unadjustable constant-current supply, or the constant flow module of scalable electric current output.
Embodiments of the invention one can realize that the light of LED aquatic animals lamp compensates automatically.
Aquarium is placed under the indoor situation; When the user when the morning, 10 o'clock was opened indoor illuminating lamp; If the intensity of room lighting is equivalent to about 20% of the pairing light intensity of pattern that the user sets up on their own, the illumination that is equivalent to aquatic animals lamp has been reinforced about 20%, in order to utilize user's room lighting fully; Photosensitive unit 40 collects the ambient light intensity of aquarium; Data transaction with light intensity is the control panel 33 that electrical signal transfer is given control module 30 simultaneously, and the electric current output with power supply after control panel 33 passes through to calculate reduces by 20%, thereby the output of lighting unit 60 is also reduced about 20%.
Like Fig. 3 and shown in Figure 4; The photosensitive-member M5 of photosensitive unit 40 adopts the photodiode of environment-friendly type; When extraneous light changes; The electric current of photodiode can change thereupon; This change in current can be the variation of voltage by one of them electric resistance changing of sampling resistor R17～R21, and the A/D converter that carries through microprocessor MCU (Micro Control Unit) then is converted into digital quantity and supplies MCU to use, and the collocation through the different resistances of sampling resistor R17～R21 can let photodiode under different illumination intensity, all keep satisfactory precision.
The present invention is built-in clock, calendar and four seasons light change curve in control panel 33; All there are corresponding preset value various season, weather and time; The user is after being provided with time and date; Light intensity and preset value that control module 30 is gathered photosensitive unit 40 compare, if the light intensity that collects is 20% of a preset value, then control module 30 can be controlled the dutycycle of PWM (Pulse Width Modulation) signals; It is reduced to 80% of preset value; And the output current of the constant-current supply module 72 of power subsystem 70 is to be directly proportional with the dutycycle of pwm signal, so output current can reduce 20% than predetermined value, thereby makes the intensity of illumination of lighting unit 60 also reduce by 20%; The light intensity of the biological institute of Shui nationality perception simultaneously then remains unchanged basically; Make control module 30 can be automatically according to the size of the power adjustment LED fluorescent tube output current of ambient light, thereby reach energy-conservation about 20%, also reduce extraneous light simultaneously to the biological interference purpose of the Shui nationality.
Extraneous light can keep relative stability at short notice under the normal condition; Light sudden change in the light compensation adjustment, and avoiding because signal is interfered, or moment illumination variation; Like pedestrian's mistake compensation that photosensitive region causes of passing by; After extraneous light changed, the light intensity of lighting unit 60 can't be adjusted immediately, but in a period of time, progressively accomplished compensation adjustment according to the compensate for rate (%/S) that the user sets.If the data computation that collects according to photosensitive unit 40 goes out the intensity of illumination of needs minimizing 20%; The compensate for rate that the user sets is 0.5%/S; Then control module 30 can control reduce by 1% intensity of illumination in per 2 seconds; Intensity of illumination just reduces 20% after 40 seconds, thereby keeps light intensity relative stability within a certain period of time, avoids aquatic organism is had a negative impact.
Therefore the present invention reduces the output of lamp current when extraneous light is stronger; When light is more weak, strengthen the output of lamp current; Through dynamic adjustment, both can fully satisfy Shui nationality existence demand, again energy savings to greatest extent to light to lamp current.
