Abstract

The invention relates to a flat lamp with light emitting diode, comprising circuit board, reflector, LEC light source, light sensitive probe, control circuit and four-line plug. Several light emitting diodes are set on the circuit board to form LED flat lighting source, which is connected together with control circuit tightly. Separate controller is canceled. Metal reflecting layer, as reflector, is plated to the face of circuit board and a light sensitive probe for inducting weather status is set and connected with solar cell and accumulator battery by four-line plug conveniently. When the flat lamp with light emitting diode is applied in the solar street lamp, the waste of control circuit is less than 2%, the service life of light source is achieved to fifty to one hundred thousand hours, the light efficiency is high to 60 lumen per watt. It is no flashing and dazzling and can be lighten for more than ten days.

Description

1. Technical field [0001] The invention relates to a solar lamp, in particular to a solar street lamp. 2. Background technology [0002] Solar street lights are more and more widely used because they meet the requirements of environmental protection and energy saving and the safety of electricity use. Existing solar street lights are mainly composed of solar cells, storage batteries, lamps, and controllers. [0003] Existing solar street lamps, whose controller is a split type, generally have large shunt of circuit components, serious voltage drop, and long feeder end, resulting in self-loss of more than 10%, even as high as 20%-30%, so the battery after passing through the controller The utilization rate of the power supply to the light source is very low: In addition, the controller does not properly protect the battery from overvoltage. When the sun is shining at noon, the solar battery is disconnected to charge the battery, resulting in low charging efficiency of the ba...
