Abstract
The utility model fully discloses a high power LED street lamp. The street lamp comprises a lamp holder and a lamp body, wherein the lamp body comprises an LED light group arranged on a LED substrate and a radiator which closely sticks to the LED substrate, the lamp holder is connected with the lamp body through the radiator, and the connection position of the lamp holder and the radiator is provided with a groove. In the utility model, the groove is arranged between the lamp holder and radiator of the high power LED street lamp, the fins of the radiator incline to the groove after the street lamp is installed, when sands are blown into the gap among the fins of the radiator, sands move to the direction of the lamp holder and finally move in the groove to be discharged; especially in the rainy day, the sand and dust which stick to the fins of the radiator and exist among the fins can be washed away owning to the washing of rainwater so that the radiator can be better cleaned and the dissipation function of the radiator can not be affected; and the radiator can meet the normal use demand of the high power LED street lamp, thus increasing the service life of the street lamp.
Description
Technical field
The utility model relates to illuminator, particularly a kind ofly makees the street lamp of illuminator with LED, and the power of the LED lamp that uses in this street lamp is high-power.
Background technology
Street lamp is the important component part of city illumination, traditional street lamp often adopts high-pressure mercury lamp, the high-pressure mercury lamp shortcoming that light efficiency is low has on the whole caused the huge waste of the energy, therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the street lamp of environmental protection has a crucial meaning to city illumination is energy-conservation.
What high-power LED street lamp was different with conventional high-pressure mercury lamp street lamp is, the efficient white light-emitting diodes that the light source of high-power LED street lamp adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder, have efficient, safety, energy-saving and environmental protection, distinct advantages such as the life-span is long, response speed is fast, colour rendering index height, can be widely used in city illumination.
High-power LED street lamp as the term suggests be power greater than more than 30 watts, adopt the street lamp of New LED semiconductor light sources.Because power is bigger, the diffusing performance of high-power LED street lamp becomes one of emphasis of each street lamp manufacturer research at present, and main way is heat-radiating substrate to be set being close on the LED installation base plate at present, is generally aluminium base, after being close to substrate large-scale radiator is set, diffusing device is close to the lamp holder of street lamp.Like this when street lamp is installed on the lamppost, the street lamp erecting device is set on road lamp cap, the light-illuminating of street lamp is to the road surface, radiator dorsad above, radiating fin stretches upwards, owing to the reason of installing, these street lamps all may be to tilt slightly downwards, when street lamp has been grown service time, because influences such as dust storm will be assembled one deck sand and dust in the gap between each radiating fin, particularly will precipitate a thick layer of sand and dust at radiator and road lamp cap joint, like this, will cause adverse influence to the work of radiator.Influence is dispelled the heat, even may influence the service life of large power road lamp.
Summary of the invention
The utility model provides a kind of high-power LED street lamp, solves in the prior art because the sand and dust precipitation causes the affected deficiency of radiator heat-dissipation.
The scheme of technical solution problem of the present utility model is: a kind of high-power LED street lamp, comprise lamp holder and lamp body, described lamp body comprises the LED lamp group that is installed on the LED substrate, the radiator of being close to the LED substrate, described lamp holder is connected by radiator with lamp body, and described radiator and described lamp holder junction are provided with the groove that runs through whole lamp holder.
In the technical program owing between the lamp holder of high-power LED street lamp and radiator, be provided with groove, reason owing to the street lamp installation, the fin of radiator tilts to groove, in the time of in the slit in the middle of dust storm blows to the fin of radiator, to flow to the lamp holder direction, flow in the groove at last and discharge, when particularly rainwater being arranged, because rain drop erosion, the sand and dust of being stained with on the heat radiator fin and between fin will wash totallyer, and can not influence the heat sinking function of radiator, reach the normal use of high-power LED street lamp, thereby increase the life-span.
Below with reference to drawings and Examples, the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment rear isometric view.
Fig. 2 is the radiator stereogram of the utility model embodiment.
Fig. 3 is Fig. 2 A-A sectional view.
Among the figure: 1, lamp holder, 2, lamp body, 3, radiator, 4, groove, 5, fin, 6, the first street lamp installing mechanism, 7, the second street lamp installing mechanism.
The specific embodiment
Embodiment 1, as shown in Figure 1 and Figure 2, and a kind of high-power LED street lamp, comprise lamp holder 1 and lamp body 2, lamp holder is provided with the first street lamp installing mechanism 6, for overlapping to a circle on the lamp holder 1 with bolting, the rounded material that rises from the lamppost can be locked in the cover and stretch to the road surface.Described lamp body 2 comprises the LED lamp group that is installed on the LED substrate and is close to the radiator 3 of LED substrate that lamp body 2 is connected with lamp holder by radiator 3, is provided with groove 4 at described radiator 3 with described lamp holder 1 junction in addition.This groove 4 runs through whole lamp holder.
In the present embodiment, described radiator 3 is cast by fine aluminium 6063, with described LED substrate be complementary on one side, one group of outward extending fin 5 is set on one side.Can guarantee the good result of dispelling the heat, simultaneously, the shell of lamp holder 1 also is to be made by aluminum metal, the part heat can be distributed by lamp shell when it is connected with radiator 3.
In addition, in the present embodiment, because lamp holder 1 is provided with the device of street lamp to the lamppost is installed, owing to install, the lamp holder 1 of whole street lamp and lamp body 2 will be downward-sloping slightly.Owing between radiator 3 and lamp holder 1, be provided with the groove 4 that sand and dust can be discharged, because the effect of gravity, gather that the sand and dust in the slit will flow to groove 4 between radiator 3 fins 5, in groove 4, discharge at last, can guarantee radiator 3 operate as normal.In order to guarantee that the sand and dust in the slit between radiator 3 fins 5 are all discharged, the end of groove 4 described herein, is equal with described radiator 3 fins 5 roots.When rain drop erosion, the sand and dust in the slit between radiator 3 fins 5 all can be discharged like this.
Embodiment 2, as Fig. 1, Fig. 2, shown in Figure 3, present embodiment is substantially the same manner as Example 1, just increased by one second street lamp installing mechanism 7, be adapted to be mounted within that tunnel etc. directly hangs over street lamp on the supporter and without the situation of lamppost, present embodiment is with the support chips of two " F " shapes of casting in the middle of the fin 5 of radiator 3.In the time of on street lamp being hung over buildings such as tunnel, can install easily.
