Description
Technical field
The utility model relates to the LED lighting technical field, relates in particular to a kind of LED constant-temperature constant-current device.
Background technology
LED is a kind of energy-saving and environmental protection, profile is little, the life-span is long and luminous strong solid light source; More and more receive liking of people, the efficient of the circuit that exists in the existing led drive circuit technology is lower, caloric value is big under high power state, the circuit volume is big and the cost problem of higher.
Summary of the invention
The technical problem that the utility model need solve is that caloric value is big under high power state, the circuit volume is big and the cost problem of higher.
The technical problem that the utility model need solve realizes through following technical scheme: a kind of LED constant-temperature constant-current device; Comprise master controller; The constant flow module that links to each other with master controller, digital displays temperature module, LED light fixture; Between master controller and LED light fixture, also be provided with the temp probe of surveying LED light fixture working temperature, described main controller also is connected with fan.
Further: in above-mentioned LED constant-temperature constant-current device, described constant flow module also links to each other with the LED light fixture with Switching Power Supply respectively.Be provided with MOS switch between described master controller and the fan as the frequency conversion switch.Described temp probe is the DS18820 type, and described digital displays temperature module is the 7LED-1 type, and described MOS switch is NK2302.
Compared with prior art; Constant-temperature constant-current device of the present invention; Comprise master controller; The constant flow module that links to each other with master controller, digital displays temperature module, LED light fixture also are provided with the temp probe of surveying LED light fixture working temperature between master controller and LED light fixture, described main controller also is connected with fan.The constant voltage Switching Power Supply provides stable electric current through constant flow module to LED; The LED lamp temperatures is read the control signal that obtains each function by master controller; Whenever surpass the one-level design temperature; Master controller will strengthen force one wind pectinid speed, surpass maximum design temperature, and master controller is controlled constant-current circuit with output pwm signal and reduced LED power.Digital displays temperature module shows Current Temperatures by master controller.In the operating state of LED light fixture, this constant-temperature constant-current device makes the LED light fixture be in the best effort environment of constant-temperature constant-current all the time.
Description of drawings
Fig. 1 is the utility model fundamental diagram.
Specific embodiments
With reference to accompanying drawing 1 and embodiment the utility model is described.
A kind of LED constant-temperature constant-current device; Comprise master controller; The constant flow module that links to each other with master controller, digital displays temperature module, LED light fixture also are provided with the temp probe of surveying LED light fixture working temperature between master controller and LED light fixture, described main controller also is connected with fan.Described constant flow module also links to each other with the LED light fixture with Switching Power Supply respectively.Be provided with MOS switch between described master controller and the fan as the frequency conversion switch.Described temp probe is the DS18820 type, and described digital displays temperature module is the 7LED-1 type, and described MOS switch is NK2302.
Temp probe DS18820 is connected the working temperature of surveying the LED light fixture in the LED light fixture aluminum component.Signal is transferred to main controller MCU through pin, and MCU carries out signal processing.Draw the signal that the temperature transition that but reads becomes digital displays temperature module 7LED-1 to show through MCU.The working temperature that shows current LED light fixture by digital displays temperature module 7LED-1.The temperature value that is divided into 4 grades through the temperature transition that the MCU pin reads is controlled 3 grades fan speed (close fan under 50 ℃ automatically, 50 ℃～55 ℃ is light breeze speed, and 55 ℃～60 ℃ is gentle breeze speed, and 60 ℃～65 ℃ is the total power wind speed).Perhaps draw temperature transition that 4 pin read and be divided into 2 grades of temperature values and control 2 grades of LED lamp power (55 ℃～80 ℃) LED power and reduce to the power that radiator can bear, close lamp more than 80 ℃ through MCU), the temperature transition classification is accomplished by the software control of MCU institute burning.
The above is a preferred embodiment of the utility model, is not breaking away under the utility model design situation, carries out any conspicuous distortion and replacement, all belongs to the utility model protection range.
