Description
Technical field
The utility model relates to a kind of LED solar street light.
Background technology
Existing LED solar street light has the following disadvantages: one is that solar panel is separated with LED lamp, adopts the way of installing respectively, installs cumbersome; Two is that the capacity gauge of solar panel to solar energy is lower; Three is that LED light source radiating effect is bad, affects service life; Four be epoxy resin in LED easily by ultraviolet interference, after working long hours, resin slowly becomes muddy, affects luminous efficiency.
Utility model content
The purpose of this utility model provides a kind of solar energy utilization ratio high for above-mentioned situation exactly, long service life, and luminous efficiency is high, LED solar street light easy for installation.The purpose of this utility model realizes by following scheme: a kind of LED solar street light, comprise bending lamp stand, one end of bending lamp stand is provided with illuminating lamp, it is characterized in that described illuminating lamp comprises lamp housing, the bottom of lamp housing is provided with lampshade, the middle part of lamp housing is provided with fin, two cross bars for installing LED light source component are provided with in lamp housing bottom fin, side is provided with solar panel by joint pin on a heat sink, a reflective mirror is respectively provided with in the both sides of solar panel, angle between described reflective mirror and solar panel is 30 degree, battery and driving power is provided with in the inside, one end of lamp housing, LED light source component is connected with driving power by wire, driving power is connected with battery by wire, solar panel is connected with battery by wire, described LED light source component comprises aluminium base and LED, described aluminium base is rectangle, by copper foil circuit plate, thermally conductive insulating layer and aluminium sheet three layers composition, upper strata is copper foil circuit plate, bottom is aluminium sheet, thermally conductive insulating layer is between copper foil circuit plate and aluminium sheet, aluminium base is provided with several bowl-type grooves, the bottom of bowl-type groove is on aluminium sheet, described LED comprises chip and fluorescent material, chip is fixed on the aluminium sheet of bowl-type groove bottom, fluorescent material is located on chip, copper foil circuit plate is connected by money with chip, described aluminium base is arranged on cross bar by screw.Because solar panel and illuminating lamp are set to one, make installation more simple, the two ends of solar panel are respectively equipped with reflective mirror, improve the capacity gauge of cell panel to solar energy; Because chip is directly installed on aluminium sheet, without the need to passing through thermally conductive insulating layer, but directly directly dispelled the heat by aluminium sheet, in addition, copper foil circuit plate not only conducts electricity, gold thread also by connecting chip distributes a part of heat, substantially increase the radiating effect of LED, extend the service life of LED, bowl-type groove the irradiating angle that can strengthen LED is set, do not re-use epoxy resin, making to work long hours also to affect the luminous efficiency of LED.It is high that the utility model has solar energy utilization ratio, long service life, the features such as luminous efficiency is high, easy for installation.
