Description

A kind of fixed structure of LED road lamp cap

Technical field

The present invention relates to a kind of street lamp erecting device, be specifically related to a kind of fixed structure of LED road lamp cap.

Background technology

The LED lighting engineering has characteristics such as energy-saving and environmental protection, the life-span is long, volume is little as light source technology of new generation, can be widely used in fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscape.Led light source adopts and carries the combination of constant-current driven module formula, DC driven.Have super low-power consumption, compare the service life of LED lamp with conventional light source, it is generally acknowledged has 100,000 hours under perfect condition.But owing to the centrality of LED lamp and the reason that need carry power supply, its temperature rises very fast, particularly in high-power, high-brightness LED lamp light source applications, the light decay of LED lamp source and its node operating temperature are contacted directly, when the node operating temperature is higher than 60 ~ C, the working life of light source will significantly descend, so LED lamp operating temperature should be controlled at below 60 ℃, could guarantee the service life more than 50,000 hours.The LED lamp all is equipped with radiator at present and lowers the temperature, but so whole LED lamp weight just greatly increases, light must have tens kilograms, recuperation has tens kilograms, problems such as the LED lamp comes off often take place in the reality. how LED lamp and lamp stand are fixed and easy for installation, just become a matter of utmost importance of LED lamp.LED lamp and lamp stand are fixing at present usually is to utilize bolt, one or a few pressing plate, because the fixedly contact of bolt is less, can come off by burn into behind permanent wind and weather, causes LED fixedly to go wrong.

The utility model content

For solving the problem that above-mentioned prior art exists, the utility model provide a kind of easy for installation, simple in structure, connect firm lamp holder fixed structure, the employing technical scheme is as follows: a kind of fixed structure of LED road lamp cap, comprise radiator, hollow pipe, its improvement is, axial centre position, the described radiator back side has groove, and there is axial fin on described hollow pipe surface, and described fin inserts in the groove.

Another optimal way of the present utility model: described radiator axial notch is one, and described groove is made of the right-angle side of two symmetries, forms a pincer that opening is little, inner big.

An optimal way more of the present utility model: have axial groove with the fin corresponding position in the described hollow pipe.

Another optimal way of the present utility model: described radiator groove one end is installed power module, and there is fixed head at described power module two ends, and fixing hole is arranged on the fixed head.

An also optimal way of the present utility model: on the radiator groove, described nut and pad one end snap in the groove described power module by nut bolt and spacers, and bolt one end stretches out outside the groove.

Another optimal way of the present utility model: described power module is fixed on the radiator groove by the holder of band internal thread hole, and described holder snaps in the groove, and screwed hole is towards the slot opening direction.

Another optimal way of the present utility model: described hollow pipe is made up of two above short tubes, and described short tube is plugged on respectively in the radiator groove.

Another optimal way of the present utility model: adopt bolt that both are fixed after described fin inserts in the groove.

Another optimal way of the present utility model: described radiator and groove are an extrusion modling of one, and described hollow pipe and last fin thereof and groove are an extrusion modling of one.

Another optimal way of the present utility model: have screw hole on the described hollow pipe.

Axial notch is directly driven in the utility model utilization on the lamp holder radiator, utilize the mode of pegging graft that hollow pipe is fixed in the groove, easy for installation, after the fin on the hollow pipe inserts in the groove, difficult drop-off, utilize screw or bolting again, feasible connection is more firm, and hollow pipe and lamp stand socket contact area are big, and the LED lamp is difficult for sliding, the groove part at hollow pipe and the fin on it, radiator and its back side adopts extruding one-body molded, and combiner is few, annexation is few.This fixed form also makes the heat on the radiator distribute by lamp stand, has further reduced the temperature of LED lamp.But the radiator groove is fixed power source also; bolt or threaded block that utilization snaps in groove fix power module, have reduced the volume of whole LED lamp, the corresponding LED erection space that increased; groove in the hollow pipe can pass some subsidiary protection cables, is used for the LED lamp holder further fixing.This structure operation is simple, easy for installation, contact area big, it is firm to connect.

The specific embodiment

Embodiment 1:

As shown in Figure 1,1 extrusion modlings of axial notch at radiator 2 and its back side, the shape that groove 1 is shaped as that two right-angle sides surround is young, tripe is big, an axial fin 5 is arranged on hollow pipe 3 surfaces, the size of fin 5 and groove 1 match and can only insert from the two ends of groove 1, have further strengthened connectivity robustness.An axial groove 4 is arranged in the back side of fin 5 hollow pipe 3, and groove 4 is used for installing the cable of some additional LED lamp holder protective devices, and hollow pipe 3, fin 5, groove 4 adopt an extrusion modling.Link together with radiator 2 in the groove 1 of hollow pipe 3 by fin 5 insertion radiators 2 back sides, adopt modes such as screw rod, bolt that fin 5, groove 1 after pegging graft are fixed.Be installed to radiator 2 about 2/3 places 3 of hollow pipes, reserve the position that power module 6 is installed in the place ahead of hollow pipe 3, power module 6 is fixed by the bolt, the threaded block that are fixed in the radiator groove 1.When adopting bolt, bolt block is stuck in the groove 1, can on bolt block, add some pads and strengthen stationarity, bolt one end stretches out 1 mouthful of groove, there is outstanding fixed head at power module 6 two ends, fixing hole is arranged on the fixed head, after bolt passes fixing hole, utilize nut to be screwed into bolt again power module 6 is fixed on the groove 1.When adopting threaded block, threaded block is inserted in the groove 1, the fixing hole of screwed hole with power module 6 two ends alignd, be screwed into bolt again power module 6 is fixed on the groove 1.Fin can also be installed in power module 6 surfaces, and this mode need not be installed power storehouse, the area of the LED lamp that need not strengthen or extend, and under the situation of same area, it is more reasonable that the LED lamp of this programme is arranged, and radiating efficiency is higher.

During use, the hollow pipe of installing on the complete LED lamp holder 3 is inserted the lamp stand front ends, utilize screw to be screwed into screw hole on the hollow pipe 3 again and lamp stand is fixed with hollow stem got final product.

Embodiment 2:

This apparatus structure relation is identical with embodiment 1, but hollow pipe 3 is divided into two or more, inserts groove 1 respectively, and this mode is suitable for the lifting mode, utilization is fixed on the holder of locating in roof, top, hole etc. and fixes, there is fixed leg at the holder two ends, and two fixed legs are parallel with holder, and two hollow pipes are pushed away to both sides respectively, be enclosed within on the corresponding fixed leg, utilize screw or bolting again, also can adjust the light angle of LED lamp by the screw hole on hollow pipe surface.

This programme is not limited to above-mentioned publicity pattern, and the distortion of any this programme is all within the protection domain of this application.
