Summary of the invention
Task of the present utility model is the defective that will overcome prior art, designs that long, color of a kind of energy-conservation, reliable, life-span is can conversion various, low temperature easily starts, and can utilize the light emitting diode road lamp of solar powered illumination.
The technical solution of the utility model is as follows:
A kind of light emitting diode road lamp, comprise assembly, the lamp housing formed by a plurality of light emitting diodes, it is characterized in that described each light emitting diode points to arrangement according to the determined illumination of distance, width, the shape of this predefined field of illumination of lamp in described lamp housing.
Described assembly be a kind of by be formed in parallel between several branch roads of being constituted of series connection after two above light emitting diode parallel connections, again also, series mixing circuit.
Described assembly is provided with the power switch circuit that controllable components is bright, go out by storage battery power supply between assembly and battery; Be connected with a solar panel with battery, between has a charge switch circuit; With solar panel, battery, power switch circuit and charge switch circuit be connected with one the charging, illumination control circuit, it can be controlled solar panel and charge a battery daytime, night by battery to assembly power supply.
Further improving is to be provided with lampshade on described lamp housing, and the sensitive surface of lampshade and described solar panel scribbles printing opacity and has the nano paint of self-cleaning function.
Furthermore, described charging, illumination control circuit detect control circuit by battery overvoltage, undervoltage detection circuit, charging control circuit and daylight and constitute; Described illumination timing control circuit is the long delay control circuit that is made of counter.
The ingenious linearity of utilizing lumination of light emitting diode of the utility model (along the luminous illumination directional property of normal direction), light emitting diode will be arranged by rectangular planes (band shape) or curved surface, the conical surface or sphere in lamp housing according to the interval of illumination, make the light of each light emitting diode can be directed to the zone that requires illumination, need not the necessary reflection shield of traditional lighting light fixture, made full use of efficient light sources, made the luminous efficiency maximization of street lamp.Because light emitting diode can start under very low temperature, the life-span is long, the shortcoming that overcome traditional high-low pressure sodium vapor lamp thus, the Halogen lamp LED energy consumption is big, the life-span short, low temperature is difficult for startup.Because the nano paint that adopted printing opacity, has a good self-cleaning function is sprayed on the sensitive surface of lampshade and solar panel, dust is difficult for sticking on lampshade and the solar panel and further can reduces the light loss that causes because of environmental pollution.Because almost entirely in visible-range, its luminous inversion or ballast of need not can be saved a lot of energy again than conventional road lamp for the spectrum of light emitting diode.Because adopt the switch control element of the minimum FET of the conduction voltage drop of knowing clearly as photovoltaic cell module, battery and light switch circuit, and the direct ground connection that makes it to drain, the efficient that discharges and recharges and throw light on further improved.Evidence, the employing of above-mentioned measure make the utility model possess good practicability.
