The utility model relates to LED eco friendly lighting, green energy in
particular relates to a multi-functional eco friendly lighting device is
a semiconductor eco friendly lighting technology.
In real life,
most people can not do without is the eco friendly lighting, which is
now mostly used for eco friendly lighting appliances, incandescent,
fluorescent energy saving lamps. These sources are bulky, although both
simple electrical circuit design strengths, but the prevalence of
traditional lamps bulky, energy consumption is relatively serious
shortcomings. Currently the application started brewing domestic
semiconductor eco friendly lighting technology is still in its infancy,
LED level only to the extent of the package, although it is higher than
traditional eco friendly lighting has been greatly improved in terms of
volume and energy, but due to the complexity of the electrical circuit
design, improved technical solutions limited; especially without charge
and discharge design, in a blackout situation is likely to cause
confusion may not illuminate the formation, thus making energy-saving
features are widely used with excellent prospects of LED light fixtures
bring a certain degree of difficulty.
The utility model for the
above shortcomings, providing multi-functional 2W Eco-Friendly Solar
Lawn Light energy-saving devices, to solve the problem of LED devices in
a power outage situation does not work. The utility model of
environmentally friendly energy-saving eco friendly lighting
multifunction devices, including light body, at least one set of
light-emitting diodes and light-emitting diodes for the PCB metal line
connection, which is characterized by:
The multifunctional
energy-saving LED eco friendly lighting device in the original eco
friendly lighting circuit added automatically charging and discharging
circuit, the automatic charging and discharging circuit comprises a
diode DbD2, D3, 04 consists of AC / DC rectifier circuit through the
capacitor d, C2, inductor L2 consisting of: type filter circuit with
integrated step-down switching module with optical coupling circuit is
connected, plus a NiMH rechargeable battery charging circuit composed;
nickel-metal hydride rechargeable batteries and boost diode with a
voltage regulator switching module and an integrated light-emitting
diode of the discharge circuit.
By designing these circuits, the
utility model a good solution to LED lights can charge and discharge
issues, making even in case of power failure, LED lights are still able
to work some time to repair equipment for the precious time.
