Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Provided by Fig. 1-3, the utility model provides a kind of self-adjusting LED street lamp, comprise: adaptive LED power supply adaptor, intensity of illumination sensor and LED lamp holder, described intensity of illumination sensor is installed in the middle part of lamp stand, its photographic hole is installed outwardly, and described intensity of illumination sensor data interface is connected with the intensity of illumination sensor input interface of adaptive LED power supply adaptor; Described LED power adapter is installed on bottom street lamp post, its shell adopts corner angle pattern, input port connects civil power 220V electric wire, output is connected with LED lamp holder, its inside comprises central processor CPU, gauge tap, voltage transformation unit, pulse-width modulator PWM, bridge rectifier unit, constant current chip, current detecting unit, inner heat components and parts and shell compact siro spinning technology, contact position scribbles nanometer thermal grease, to ensure radiating effect;
The data that in described adaptive LED power supply adaptor, CPU gathers according to intensity of illumination sensor; adjust size of current by PWM in good time; thus control the brightness of LED; when current detecting unit detects current overload; CPU is by controlling closing control switch; play the effect protecting whole device.
Operation principle is as follows:
(1) in the process that the dim light of night is dimmed gradually at dusk, by being arranged on the intensity of illumination sensor Real-Time Monitoring ambient lighting intensity on lamp stand, when intensity of illumination is not lower than particular value (affecting the visual light intensity critical value of traffic safety), automatically LED power adapter output switch is opened, unlatching LED street lamp is powered, LED street lamp light intensity is adjusted, to meet lighting demand by the mode adjusting LED power adapter output current size from small to large gradually.Along with the colour of sky is more and more black, LED power adapter self-adaptative adjustment output current size, above intensity of illumination remains on steady state.
(2) in the process that dawn, the colour of sky brightened gradually, by being arranged on the intensity of illumination sensor Real-Time Monitoring ambient lighting intensity on lamp stand, LED street lamp light intensity is adjusted, to meet lighting demand by the mode adjusting LED power adapter output current size from big to small gradually.When intensity of illumination is higher than particular value (natural daylight is enough to the critical value ensureing lighting demand), automatically cuts off LED power adapter and export.
(3) to overcast etc. in summer strong convective weather, still applicable policies (1); It is gradually fine that rain crosses weather, still applicable policies (2).
(4) time period (morning 0 or other times point (setting as required)) at dead of night, because the magnitude of traffic flow obviously reduces, intensity of illumination is not needed too high, LED power adapter reduces stabilized intensity value automatically for certain particular value (obtaining result depending on specific road section investigation), can reach on the one hand and save electric energy to greatest extent, on the other hand also can extension device service life.
(5) under LED power adapter cuts off output electric power thus supplied completely, whole device is switched to the sleep pattern of low-power consumption immediately, and Real-Time Monitoring environmental light intensity.Once intensity of illumination is not enough, device is waken up immediately, then enters and opens LED street lamp powering mode.
