Description
Technical field the utility model relates to a kind of communal facility, especially a kind of lighting apparatus.
Background technology is well-known, and street lamp is a most important lighting apparatus in the urban transportation.At present, street lamp all mostly adopts the powered lighting systems, also has fraction to adopt solar energy or wind energy powered lighting mode, and still, all there are many design defect in above-mentioned lighting system, electric energy lighting system particularly, serious waste electric energy.And all there are difficulties such as cost height, installation complicacy in wind energy and solar lighting mode, are not suitable for promoting the use of.
The purpose of summary of the invention the utility model provides a kind of Laval nozzle formula thermo-electric generation LED street lamp that utilizes the temperature difference to generate electricity and throw light on.
The utility model mainly comprises lamp stand and lamp holder, and the lamp stand main body is the open tubular column structure, and root is the truncated cone-shaped structure, and air admission hole is offered on the root surface; The first half table wall of lamp stand is that light absorbent, Lower Half table wall are reflectorized material; In the lamp stand first half inside battery, generator, fixed mount and Laval nozzle are installed successively from top to bottom; Battery links to each other with generator, and generator is fixed on directly over the Laval nozzle through fixed mount; Alternator shaft connects flabellum, and flabellum places Laval nozzle inside center zone; Lamp holder is installed in the lamp stand top through link, and lamp holder is connected with battery, photosensitive switch.
During use, the lamp stand first half adopts light absorbent to process, and Lower Half adopts reflectorized material to process; Make that two parts form distinct temperature difference up and down, the temperature of the first half is higher than the temperature of Lower Half, and upper end air pressure is lower than lower end air pressure; Spring up so form air-flow, air is gushed out, from the air admission hole entering of lamp stand root and from the lamp stand top when air-flow process Laval nozzle; Blow flabellum rotation, flabellum drives generator work, and generator produces electric energy and to charge in batteries.During illumination, battery is that lamp holder provides electric energy.Photosensitive switch can judge whether turning circuit voluntarily according to external light intensity, realizes automatic control function.
Compared with present technology, the beneficial effect of the utility model is: rational in infrastructure, convenient and practical, function is peculiar, simple installation, effectively utilize the wind power generation illumination, and can throw light on voluntarily according to external light intensity, be particularly suitable for promoting the use of.
Description of drawings Fig. 1 is the stereochemical structure sketch of the utility model.
The specific embodiment mainly comprises lamp stand 1 and lamp holder 2 in the stereochemical structure sketch of the utility model shown in Figure 1, the lamp stand main body is the open tubular column structure, and root is the truncated cone-shaped structure, and air admission hole 3 is offered on the root surface; The first half table wall of lamp stand is that light absorbent, Lower Half table wall are reflectorized material; In the lamp stand first half inside battery 4, generator 5, fixed mount 6 and Laval nozzle 7 are installed successively from top to bottom; Battery links to each other with generator, and generator is fixed on directly over the Laval nozzle through fixed mount; Alternator shaft connects flabellum 8, and flabellum places Laval nozzle inside center zone; Lamp holder is installed in the lamp stand top through link, and lamp holder is connected with battery, photosensitive switch 9.
