Description
Technical field
The utility model relates to the Application of Solar Energy field, relates in particular to a kind of system that LED street lamp luminous power is carried out the intelligence adjusting.
Background technology
Along with the aggravation of severe power shortage problem, account for the public illumination electricity consumption greatly of city public electricity-using, the increasing solar street light that does not need civil power of selecting for use.Along with the development of LED (Light Emitting Diode, light-emitting diode) technology, to have a luminosity big because of it, and volume is little, and power consumption is little, becomes the future trend of illuminating industry gradually.So existing solar street light uses the light source of the fixing LED system of luminous power as illumination mostly.Owing to turning off the light from turning on light to of solar street light, natural light intensity changes, so in fact the fixing LED system of power has wasted many electric energy.Simultaneously LED its luminous efficiency under conditions such as different electric intensity of flow and ambient temperature is also different; So same its luminous flux that sends of power is also different, another conveniently can make reduce the useful life of LED again therefore not combine the power adjustments of LED self light-emitting efficiency characteristics to waste electric energy on the one hand.
The utility model content
To the problems referred to above, the purpose of the utility model be to provide a kind of can be according to the size of surrounding environment light intensity, and combine LED self light-emitting efficiency characteristics, regulate the system of LED luminous power automatically, thereby save the energy and prolong useful life of LED.
The above-mentioned purpose of the utility model reaches through following technical scheme:
LED street lamp intelligent power regulating system; Comprise LED driver module, LED; Also comprise the light detection means that is used for the testing environment light intensity of part at least; At least part be used for send the main control chip module of conditioning signal and the power conditioning module that is used for sending power signal at least partly according to environmental light intensity and LED light-emitting efficiency characteristics according to conditioning signal;
Said light detection means output is connected with the main control chip module input; The main control chip module output is connected with the power conditioning module input; The power conditioning module output is connected with LED driver module input, and LED driver module output is connected with the LED input.
Further, said power conditioning module main devices is high-end low side chip for driving.
The beneficial effect of the utility model is:
The utility model detects light and the mixed environmental light intensity of natural daylight that LED sends through light detection means; Main control chip module is according to environmental light intensity and LED light-emitting efficiency characteristics; Utilize power conditioning module and LED driver module to regulate the luminous power size of LED; So can adjust the light that LED makes it to send the phase suitable intensity at any time, thereby reach energy savings, prolong the LED purpose in useful life; Further, use high-end low side chip for driving but not the basis integrated circuit have the integrated level height as the power conditioning module main devices, commercial production simple flow, the advantage that industrial cost is cheap.

Fig. 1 is the construction module sketch map of the utility model specific embodiment.
Embodiment
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.The description to alternative features is to being equal to the description of technical characterictic, must not being regarded as the donation to the public in this specification simultaneously.
Term in this specification (comprising any claim, summary and accompanying drawing) like no specified otherwise, all is defined as the peculiar implication in this area if having the peculiar implication of general sense and this area simultaneously.
As shown in Figure 1, be the construction module sketch map of the utility model specific embodiment.LED street lamp intelligent power regulating system; Form by LED driver module, LED, light detection means, main control chip module and power conditioning module; This light detection means output is connected with the main control chip module input; The main control chip module output is connected with the power conditioning module input, and the power conditioning module output is connected with LED driver module input, and LED driver module output is connected with the LED input.
When solar street light is provided with the bright lamp of beginning according to set program, also have more intense available light in the general surrounding environment, this point is very common in summer.In such environment, the LED lamp need be with peak power work, and the luminous combination natural daylight of LED can satisfy public illumination fully.Along with weakening of available light, just need LED to increase power gradually, till maximum power.So to morning next day, available light strengthens again gradually, needs LED to reduce power gradually, is 0 to extinguish or till solar street light extinguishes according to set program setting up to power.Simultaneously such adjusting again need with the light-emitting efficiency characteristics of LED.For example; The light-emitting efficiency characteristics of LED of supposing certain solar street light is 70lm/w when 20mA in 25 degrees centigrade environment, is 80lm/w when 25mA; When 30mA 75lm/w; Then should the electric current through this LED be remained on 25mA this moment as far as possible, regulate output power, and then accomplish the task of the size of the luminous luminous flux of this LED of control through the size of voltage; If in 30 degrees centigrade environment, when 20mA 75lm/W, when 25mA 74lm/w, when 30mA 70lm/w, then should the electric current through this LED be remained on 20mA this moment as far as possible.
The system of the utility model is by following process work in the said process: available light has been mixed at the solar street light place to light detection means and the luminous environment of LED detects, and with repeated detection in the short time to environmental light intensity send to main control chip module; Main control chip module is according to pre-set programs; Utilize the power meter of this environmental light intensity that repeatedly measures and LED at that time to calculate the light-emitting efficiency characteristics of LED at this moment; And then calculate electric current and the magnitude of voltage that to supply with LED, and this current/voltage value is sent to power conditioning module as conditioning signal; After power conditioning module receives conditioning signal, select the suitable current signal to send to the LED driver module as power signal according to conditioning signal; The LED driver module increases or reduces to supply with the curtage to LED under the effect of this power signal, thereby reaches the purpose that intelligence is regulated LED power.And finally reach the saving energy, postpone the LED purpose in useful life.
