Description
Technical field
The utility model relates to street lamp, especially a kind of radiator structure of high-power LED road lamp cap.
Background technology
Present high-power LED road lamp cap; Usually being employed in the lamp body back side is provided with radiating fin and dispels the heat; The street lamp that has also carries out forced heat radiation with fan; But can produce great amount of heat during high-power LED road lamp cap work, make the lamp body temperature inside very high, only depend on outside fin can't reduce internal temperature effectively.So direct life-span that influences each part in the light fixture, along with can causing street lamp brightness, the temperature rising reduces, promptly produce the light decay phenomenon.
Summary of the invention
The purpose of the utility model is to provide a kind of LED road lamp cap with heat dissipation channel.
A kind of LED road lamp cap comprises panel and panel-mounted LED lighting module.Be formed with the heat radiation chamber in the said LED road lamp cap.Position near said LED road lamp cap head on the said panel has the air outlet that communicates with the chamber of dispelling the heat.Said LED road lamp cap afterbody has the air intake vent that communicates with said heat radiation chamber.
In a preferred embodiment, said air intake vent is positioned at one of upper/lower positions: (1) LED road lamp cap supports the position that its lamp stand links to each other when using, and said heat radiation chamber is communicated with lamp stand inside through air intake vent; (2) support the position that its lamp stand links to each other when using near the LED road lamp cap, said heat radiation chamber is communicated with ambient atmosphere through air intake vent.
In a preferred embodiment; Described LED road lamp cap comprises lamp body and the lamp stand head that is connected with lamp body; Said lamp body comprises said panel and the lampshade that fastens with panel, is provided with power source cavity in the said lamp stand head, is provided with the power module that is electrically connected with the LED lighting module in the power source cavity; Exist at interval between said LED lighting module and the lampshade, form a cavity; Said power source cavity and said cavity constitute said heat radiation chamber, and said air intake vent is positioned at said lamp stand portion end to end.
In a preferred embodiment, be formed with the multi-disc radiating fin on the said lampshade outer surface.
In a preferred embodiment, said air outlet and air intake vent place are provided with Air Filter.
In a preferred embodiment, said air outlet comprises a plurality of grooves or the through hole that is formed on the panel.
In a preferred embodiment, said air intake vent comprises at least one through hole or groove.
Be provided with the heat radiation chamber that communicates with ambient atmosphere in the LED road lamp cap of the utility model; Can import outside normal temperature air, produce cold-hot air convection, take away the work calories that the LED lighting module produces in the lamp holder by this; Effectively reduce the street lamp internal temperature, guarantee street lamp service life.
Description of drawings
Fig. 1 is the stereogram of the LED road lamp cap of an embodiment.
Fig. 2 is the figure that decides what is right and what is wrong of LED road lamp cap among Fig. 1.
The specific embodiment
To combine specific embodiment and accompanying drawing that the utility model LED road lamp cap is described in further detail below.
As depicted in figs. 1 and 2, in the preferred embodiment, the LED road lamp cap mainly comprises lamp body 10, the lamp stand head 20 that is connected with lamp body 10 and is arranged at the LED lighting module 30 on the lamp body 10.
Wherein, lamp body 10 is cuboid substantially, comprises panel 12 and the lampshade 13 that fastens with panel 12.LED lighting module 30 is fixed on the panel 12, and has certain intervals between itself and the lampshade 13, forms a cavity 14.Position near LED road lamp cap head on the panel 12 has the air outlet 15 that communicates with cavity 14.In the present embodiment, air outlet 15 comprises a plurality of grooves that are parallel to each other of opening symmetrically on panel.Air outlet 15 inboards also are coated with Air Filter, prevent that effectively dust from getting into the inside of LED road lamp body.Be formed with multi-disc radiating fin 16 on lampshade 13 outer surfaces, so that lamp holder is carried out auxiliary heat dissipation.
The afterbody of lamp stand head 20 has the air intake vent 24 that communicates with power source cavity 22.In the present embodiment; Air intake vent 24 comprises many grooves that cardinal principle is parallel; This groove supports the position that its lamp stand links to each other when using near the LED road lamp cap; On the one side of joining with panel 12 that specifically is positioned at lamp stand head 20, thereby allow outside air to get in the LED road lamp cap in use, can prevent that again rainwater from getting in the LED road lamp cap.Air intake vent 24 inboards also are coated with Air Filter, prevent that effectively dust from getting into the inside of LED road lamp body.
Expect that easily among other embodiment, air outlet 15 and air intake vent 24 can comprise the combination of a plurality of through holes or through hole and groove.Air intake vent 24 also can be positioned at the LED road lamp cap and support the position that its lamp stand links to each other when using, and the heat radiation chamber is communicated with lamp stand inside through air intake vent, air inlet is set on lamp stand at this moment again can realizes the effect that communicates with the foregoing description.
In the work, LED lighting module 30 constantly produces heat with power module 23, makes the temperature in the LED road lamp cap be higher than outer atmospheric temperature gradually, thereby makes the inside and outside temperature difference that produces of LED road lamp cap.Because the head of LED road lamp cap is generally a little more than its afterbody in using; Hot-air in the LED road lamp cap will rise from air outlet 15 and flow out; The heat radiation chamber of extraneous normal temperature air in air intake vent 24 constantly is inhaled into the LED road lamp cap, be LED lighting module 30 and power module 23 coolings simultaneously.
The utility model is not utilizing extra driven by energy, the LED road lamp cap is not being carried out utilizing natural principle under the situation of big structural modification, outside air is flowed in the LED road lamp cap lower the temperature for it, has the advantage that structure and technology are simple, cost is low.
Though the description to the utility model combines above specific embodiment to carry out,, those skilled in the art that can carry out many replacements, modification and variation according to above-mentioned content, be conspicuous.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
