Intelligent control of a PV-Wind powered LED street light with PV-power augmentation by solar reflector

Patent pending

A solar powered LED street lamp with automatic light control comprises a photovoltaic module with PV-power augmentation by solar reflector and jet wind turbine, a brightness/darkness detection sensor, a lamp pole, a LED lamp, a LED reflector direction control, a base, an accumulator storage battery, a central controller and an infrared human body inductor, wherein the solar photovoltaic board is mounted on the top end of the lamp pole, the LED direction board or billboard is mounted on the lamp pole, the accumulator storage battery and the central controller are situated in the base, the infrared human body inductor and the LED lamp are mounted on the transversal bar of the lamp pole, and a plurality of LEDs are arrayed so as to constitute the characters or the marks on the LED direction board or billboard.

The invention relates to high active groove shape reflection shield and its application in the LED street lamp. The unit of the groove shape reflection shield is bar groove structure of which bottom is set two rows of light source mounting hole; two sides has symmetrical side curved surface illuminator; two ends have symmetrical end face illuminator. The illuminators are extended from groove bottom to binding edge.

The LED street lamp includes a power supply adapter, a constant current driving unit; wherein the constant current driver is in series connection with output terminal of the power supply adapter and supplies power to the LED lamps; an automatic light-regulating energy-saving controller is also included and signal output terminal of the automatic light-regulating energy-saving controller is connected with the constant current driving unit. The LED lamps form a plurality of working modules and each working module is connected with an independent constant current driving unit. The automatic light regulating controller controls lighting and shutting off time of the working modules. The LED street lamp energy saving method includes dividing daily working time of the LED street lamp into several working time sections according to different light application amount, and controlling lighting of different number of the working modules in different time sections via the automatic light regulating controller according to different required light amount.

The present invention involves a high brightness, large irradiation range and good evenness degree LED street light which can meet the use requirements of street lights. It is characterized by: the installing LED arcuate plate is the metal curved body which thickness at least is >= 10 mm, at least the inner concave is polygon cambered surface which is abutted by several plat surfaces, the width of the normal line ejection light mutual abutting configuration of said polygon cambered surface at least is the three times of light length, the LED combined light source is the LED light strip which number is same with the number of polygon cambered surfaces, and the LED combined light source is bonded flatly on the surfaces of the inner concaves. The light enlarges the irradiation area, also improves the luminance evenness in the irradiation area, thereby meets the three big indicating requirements of irradiation area, average luminance and luminance evenness, and also solves the LED temperature raising problem. For example the 10 meters height, Centre vertical ground irradiance 28 lx, 15 m from the edge of the Centre the illumination of centre vertical with the ground is 28 1x, the illumination of edge away the centre 15m is 10 1x, the evenness is 0. 36.
