Embodiment Construction

[0023] Such as figure 1 As shown, the solar LED lamp provided by this embodiment includes a lamp body 1 , a light source 2 and a driving assembly 3 .

[0024] combine figure 2 As shown, the lamp body 1 serves as the bearing member of the light source 2 and the driving assembly 3, and determines the appearance and shape of the entire lamp. The lamp body 1 includes a heat dissipation base 101 and a housing 102 , the heat dissipation base 101 is arranged in the housing, on which the light source 2 is installed, and the housing 102 is provided with a light-transmitting window. In addition to the function of mechanically connecting the light source 2, the heat dissipation base 101 is mainly used to increase the heat dissipation area of ​​the light source 2, so as to ensure the life of the lamp. In addition, the structural design of the shell 102 can speed up the heat dissipation effect through the circulation of the wind, reduce the wind resistance, and reduce the pressure on th...

Abstract

The invention relates to a solar LED (light emitting diode) lamp, which comprises a lamp body, a light source and driving components. The driving components comprise a solar panel input port, an energy storage battery port, an LED lamp output port and a driving circuit. The driving circuit comprises an MPPT (maximum power point tracking) +DC (direct current) -DC (direct current) circuit, an LED controller circuit, a solar voltage illuminance detection circuit, a DC-DC driving circuit, a charging voltage current detection circuit, an LED driving circuit, an LED current detection circuit, a DSC (digital signal controller), a key input circuit and an LCD (liquid crystal display) circuit. By integrating a charging controller and an LED driver into a same circuit, installation is simple, and cost is low; by adding a solar maximum power tracking circuit, an MPPT algorithm and an input-and-output protection circuit, the solar LED lamp is more efficient and more reliable, and popularization of the solar LED lamp is realized really.

Description

technical field [0001] The invention relates to the technical field of LED lighting and solar photoelectricity, in particular to a solar LED lamp. Background technique [0002] In today's world, major energy sources such as petroleum, coal, and natural gas are facing the danger of resource depletion. Environmental protection and energy conservation have become the goals pursued by all walks of life worldwide. LED is called the fourth-generation lighting source. With its characteristics of energy saving, environmental protection, long life, small size, and short response time, it has been widely used in various indications, displays, lighting and other fields. At the same time, solar energy is a kind of clean green energy. The combination of the two will obtain high energy utilization rate, high safety performance and reliability, and realize energy saving, environmental protection, safe and efficient lighting system, which is a perfect combination. [0003] At present, the ...
