Description

The LED street lamp

Technical field

The utility model lighting relates in particular to the LED street lamp, the particularly a kind of intellectualized LED street lamp that can regulate illumination brightness as required automatically.

Background technology

Road lighting is meant and luminaire is set for necessary visibility being provided for vehicle and pedestrian at night on road.Road lighting can improve transportation condition, alleviates driver fatigue, and helps improving road passage capability and guarantee traffic safety, also can beautify the appearance of the city.

The method of time switch lamp is adopted in the road lighting of prior art more, just in a certain setting-up time section, turns on light, however different seasonal; The time phase difference of colour of sky blackening is bigger, even when often summer is very bright, just turn on light; And winter, it was pitch-dark, and street lamp is not also opened.And the needed illumination brightness of varying environment is also different, but the road lighting of prior art adopts is the lighting system of unified brightness, and in wagon flow less more with wagon flow after midnight first half of the night, adopts the illumination of equal brightness, comparatively waste.

In addition; Though it is to adopt light intensity to detect the open and close of assist control street lamp that a kind of improved street lamp is arranged; But in the actual environment, natural intensity variations is progressively and slowly, and often light intensity is also just turn-offed street lighting and can be caused the unsafe hidden danger of traffic for acquiring a certain degree.Therefore, it is rational inadequately coming the switch street lighting through a threshold decision.

In addition, gas-discharge lamp is adopted in the road lighting of prior art more, and noxious pollutants such as contained mercury, lead, benzene, bromine, cadmium in the gas discharge light fixture can be at the discarded after stain environment of bulb, and luminous efficiency is efficient inadequately.
