Description
Technical field
The utility model relates to a kind of light fixture, according to setting up, relates to a kind of semiconductor plant growth lamp that can automatic regulating lightness.
Background technology
Semiconductor plant growth lamp can effectively promote the growth of plant, therefore in agricultural production, obtains a wide range of applications.Although compare with traditional plant growth lamp, semiconductor plant growth lamp has advantages of economize on electricity environmental protection, and the long-term power consumption using is still very large.One of them reason is exactly in the situation that some surround lightings are more intense, and semiconductor plant growth lamp is the same with the power consumption under low light condition, causes the waste of electric power.
Summary of the invention
Technical problem to be solved in the utility model is: in the situation that extraneous surround lighting changes, the brightness meeting of semiconductor plant growth lamp changes thereupon, avoids unnecessary power consumption.For this reason solve the problems of the technologies described above, the utility model provides a kind of semiconductor plant growth lamp that can automatically regulate lamp brightness, adopt optical sensor to carry out the variation of acquisition environment light and adopt feedback circuit to change the electric current of plant growth lamp with the brightness of adjusting lamp, to reach the needs that can meet plant growth, the object that can economize on electricity again.
The utility model is achieved by the following technical solution: the variation optical sensor module that comprises acquisition environment light, be connected the amplifier module that the photosignal of optical sensor collection is amplified with optical sensor module, the brightness settings module being connected with amplifier module, the constant-current control module being connected with brightness settings module, the LED array module being connected with constant-current control module, to the switch power module of above-mentioned module for power supply.
The beneficial effects of the utility model are automatically to regulate the brightness of semiconductor plant growth lamp according to surround lighting, have obvious power savings.

Embodiment
As Figure 1-3, a kind of semiconductor plant growth lamp that can automatic regulating lightness, the variation optical sensor module 1 that comprises acquisition environment light, be connected the amplifier module 2 that the photosignal of optical sensor collection is amplified with optical sensor module 1, the brightness settings module 3 being connected with amplifier module 2, the constant-current control module 4 being connected with brightness settings module 3, the LED array module 5 being connected with constant-current control module 4, to the switch power module 6 of above-mentioned module for power supply.
Plant growth lamp adopts LED light-emitting diode as illuminating source, utilizes LED array module 5 that a plurality of LED light-emitting diodes are connected with power supply by serial or parallel connection; Utilize switch power module 6 to control the switch of plant growth lamp; It is characterized in that: it is the variation according to ambient light intensity, adopt feedback circuit to change the electric current of semiconductor plant growth lamp, automatically regulate the brightness of semiconductor plant growth lamp.Switch power module 6 adopts a Switching Power Supply, and input voltage 220V exchanges, output 24V direct current, and power configures on demand, and efficiency is greater than 85%.
Adopt optical sensor module 1 to carry out the variation of acquisition environment light.Optical sensor module 1 is comprised of fixed resistance R2 and photo resistance R4, and the luminous intensity that photo resistance R4 accepts is larger, and its resistance is less, and the voltage signal of output is just lower.The luminous intensity of accepting is less, and its resistance is larger, and the voltage signal of output is just higher.
Utilize amplifier module 2 amplifying from optical sensor photosignal out.Amplifier module 2 is comprised of U1A operational amplifier LM358 and R1, R5, is an in-phase amplifier.It is delivered to for setting the potentiometer R3 of brightness amplifying to be about 10 times from optical sensor photosignal out.
Utilize brightness settings module 3 the photosignal amplifying, take out on demand a part, deliver to constant-current control module.Brightness settings module 3 is potentiometer R3, and it takes out a part on demand the photosignal amplifying, and delivers to constant-current control module.The size of its resistance, need regulate according to the actual requirement of on-the-spot brightness.
Described constant-current control module 4 consists of U1B operational amplifier LM358 and Q1 triode, R6 current sampling resistor; Brightness settings voltage connects the in-phase end of U1B operational amplifier, and R6 current sample voltage connects the end of oppisite phase of U1B operational amplifier.Due to the anti-phase amplifying power of high power of operational amplifier, make the voltage precision on R6 follow brightness settings voltage, play the numerical value of the current following brightness settings voltage that flows through the electric current of R6, flows through LED light emitting diode matrix.Brightness settings magnitude of voltage, after certain value of artificial setting, changes along with the variation of external detection light: illumination is stronger, and its value is lower, and electric current is less, and LED light emitting diode matrix is darker, until extinguish.Illumination is more weak, and its value is higher, and electric current is larger, and LED light emitting diode matrix is brighter, until maximum.According to surround lighting, automatically regulate the brightness of semiconductor plant growth lamp, there is obvious power savings.
