LED Stand-alone type LED street light with solar system

摘要

The present invention relates to an independent LED streetlight applied with a solar system, which comprises: a solar module for generating power through a solar light source; a battery for storing electricity generated by the solar module; an LED lamp for receiving power from the battery to emit light; and a pillar for supporting the LED lamp. The streetlight applied with a solar system further comprises a boosting circuit for boosting voltage output from the battery to DC 31V to supply the same to the LED lamp. According to the present invention, voltage of DC 12V output from the battery is programmatically boosted to DC 31V, which is a standardized voltage of the LED lamp through the boosting circuit such that power lost in a conventional boosting process of voltage through a mechanical device such as an inverter and a converter and power consumed for driving a mechanical device can be reduced, thereby inducing a stable operation of the streetlight with the power produced by solar power generation. In addition, a theft of a battery arranged inside the pillar by other people is completely prevented through an anti-theft means to prevent a loss of money due to the theft of the battery, thereby practically realizing the streetlight applied with a solar power generation system. Furthermore, a proper tilt of a solar module generated by sunlight can be simply set through a tilt adjustment means in accordance with conditions such as a position, an environment, etc. in which the streetlight is installed, thereby further inducing a stable operation of the streetlight.
