Fig. 2 is the cell structure schematic diagram at LED street lamp top in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the LED street lamp of the present embodiment comprises: LED group 3, power-supply controller of electric are (not shown, can be arranged in lamppost 1, also can be embedded in underground), fan 4, temperature sensor 5, hold the container cavity 2 of LED group 3 and there is the lamppost 1 of hollow cavity.Power-supply controller of electric connects LED group 3, fan 4 and temperature sensor 5 respectively.Container cavity 2 is positioned at above lamppost 1, and is communicated with the hollow cavity of lamppost 1.Container cavity 2 has an extension 21 relative to lamppost 1, and LED group 3 and temperature sensor 5 are positioned at extension 21.Temperature sensor 5 is positioned at extension 21, from LED group 3 close together, can judge the temperature of LED group 3 relatively accurately.In order to arrive good radiating effect, container cavity 2 is made for insulating heat-conduction material, and the roof of container cavity 2 region relative with lamppost 1 and each sidewall are equipped with ventilation lattice screen 22, namely the roof of container cavity 2 is positioned at the part directly over LED group 3 is a whole block material (keeping off the rain or other foreign material).Fan 4 is arranged on ventilation lattice screen 22 place of any one sidewall in container cavity 2.
Power-supply controller of electric is LED group 3, fan 4 and temperature sensor 5 are powered, and the temperature of active obtaining temperature sensor 5 Real-Time Monitoring, and send the instruction of rotating to fan when temperature exceedes temperature threshold (as 40 degrees Celsius) of setting.According to season, power-supply controller of electric just can be set in summer and go active obtaining temperature, can also according to exceed temperature threshold number, control the rotary speed of fan.
The container cavity of the accommodation LED group of the LED street lamp of the present embodiment adopts insulating heat-conduction material to make, and chamber wall is provided with ventilation lattice screen 22, therefore relative to the mode of the container cavity chamber wall upper shed in prior art only near LED group, there is radiating effect well, add the service life of LED group.And can judge whether to start fan, even if also good radiating effect can be reached in the summer of sweltering heat according to the temperature conditions in container cavity.
In order to prevent fan 4 to be caught in the rain, above fan 4, be also provided with rain cover 6.
In order to prevent rainy day rainwater from wafing in LED group 3, each bar grating of ventilation lattice screen 22 is in the horizontal direction away from the direction with respect to the horizontal plane downward-sloping setting of described LED group 3, and inclination angle can be 45 degree.As in Fig. 1, also can not waft in LED group 3 to the rainwater waftd to the right, avoid the damage that rainwater may cause LED group 3.
Because the circuit of LED group 3 upwards connects LED group 3 from the power supply of underground along lamppost 1 usually, because opening is arranged at LED street lamp top, on rainy day, the especially large rainy day, rainwater may cause circuit to damage.Therefore as shown in Figure 2, each grating base of the ventilation lattice screen 22 of container cavity 2 roof is formed with guiding gutter 221, guiding gutter 221 is obliquely installed, and the grid of the ventilation lattice screen 22 of connection side, one end lower in the horizontal direction in the two ends of guiding gutter 221.Such rainwater, along the grid guiding ground of guiding gutter 221 ventilation lattice screen 22 from the side, is unlikely to the cavity that too many rainwater falls into lamppost 1 and forms ponding, avoid ponding long period of soaking circuit to a certain extent and cause damage to circuit.
In the present embodiment, the sidewall of lamppost 1 away from container cavity 2 one end is formed with some air-vents 11.Air-vent 11 is arranged on lower position, certain help is had to eliminating rainwater, stack effect can be formed in addition and (namely utilize the difference of hot-air rising principle and the high lower pressure differential of lamppost 1, realize the flowing from bottom to top of air, as indicated by the dashed arrow in fig. 1), air is flowed and takes away the heat sent when LED group 3 works, and under the help of fan 4, accelerate the flowing of air, thus further increase radiating effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
