Abstract
The invention relates to the technical field of lighting lamps, in particular to a light-emitting diode lighting lamp with a hollowed-out channel heat radiator. The lighting lamp disclosed by the invention comprises a heat-radiating seat which is provided with an annular hollowed-out cavity, wherein a lamp holder opening and a lamp body opening are respectively arranged at the outer side of a lamp holder end of the cavity and at a bottom end of a lamp body end of the cavity; during installation, the light-emitting diode lighting lamp is generally installed vertically, when a lamp body works, the heat of the lamp body is transmitted to the heat-radiating seat, air in the cavity is about to flow upwards under a heated condition and flows out upwards from the lamp holder opening of the lamp holder end, cold air is introduced in from the lamp body opening for compensation, thus, the lamp holder opening, the cavity and the lamp body opening constitute a circulating air flow channel so as to generate a chimney effect and form intense convection heat radiation for the heat-radiating seat; and the heat-radiating seat can be used for radiating heat in transmission, convection and radiation manners and has a good heat-radiating effect, so that the heat generated by the lamp body of the light-emitting diode lighting lamp is timely transmitted away and dispersed, the normal operation of the light-emitting diode lighting lamp is ensured, and the service life of the light-emitting diode lighting lamp is prolonged.
Description
Technical field
The present invention relates to field of illumination lamp technology, refer in particular to LED illumination lamp with hollow out passage radiator.
Background technology
Illuminating lamp is LED illumination lamp (LED lamp) especially, need carry out radiating treatment, and common LED illumination lamp is formed by setting gradually lamp holder, radiating seat, lamp body; Lamp body is the source of heating, on the heat heat loss through conduction seat of lamp body, through radiating seat heat is conducted, to ensure the operate as normal of LED illumination lamp.Usually radiating seat is the entity shape; Carry out the heat conduction with working environment, the heat conduction is carried out with transmission, convection current, radiation, generally speaking; The space environment air flow property of LED illumination lamp work is less, and the topmost heat conduction of radiating seat is main with transmission, radiation; But when radiating seat passed to air with heat, the heat transfer performance of air was not good, the influence heat radiation; Usually radiating seat is made up of metal material, neither be very strong to thermal-radiating performance; Therefore common radiating seat mostly exists radiating effect undesirable, influences the heat radiation of LED illumination lamp lamp body, influences the operate as normal of LED illumination lamp, shortens the service life of LED illumination lamp.
Summary of the invention
The invention reside in not good and problem that cause, and the LED illumination lamp with hollow out passage radiator that overcomes the above problems is provided to the radiating seat radiating effect of present LED illumination lamp.
For achieving the above object, the present invention adopts following technical scheme:
LED illumination lamp with hollow out passage radiator; Said illuminating lamp is formed by setting gradually lamp holder, radiating seat, lamp body; Said radiating seat is provided with the cavity of ring-type hollow out, and cavity is provided with lamp holder opening, lamp body opening respectively at the outside and the lamp body bottom end of lamp holder end.
The standard-sized sheet that wherein said lamp body opening is a ring-type is decontroled mouth, and said lamp holder opening is the rectangular opening that the border is uniformly distributed with.
Wherein said radiating seat increases setting gradually to lamp body direction size.
The fuisw rib that axial direction is set of wherein said cavity.
The corresponding setting of wherein said fuisw rib with the middle position of lamp holder opening.
Beneficial effect of the present invention is: the illuminating lamp of radiating seat of the present invention, radiating seat are provided with the cavity of ring-type hollow out, and cavity is provided with lamp holder opening, lamp body opening respectively at the outside and the lamp body bottom end of lamp holder end; During installation, the general vertical installation of LED illumination lamp is when lamp body is worked; On the heat heat loss through conduction seat of lamp body, under the situation that the air in the cavity is heated, can upwards flow; Upwards flow out from the lamp holder opening of lamp holder end, cold air gets into from the lamp body opening and replenishes, and lamp holder opening, cavity, lamp body opening form the gas flow of a circulation like this; Form " stack effect ", form the strong heat loss through convection of radiating seat; Radiating seat can dispel the heat with transmission, convection current, radiation, good heat dissipation effect, and the heat that the LED illumination lamp lamp body is produced is in time led away and is scattered, and ensures the operate as normal of LED illumination lamp, prolongs the service life of LED illumination lamp.
Description of drawings
Fig. 1 partly cuts open structural representation for the present invention
Fig. 2 is an illuminating lamp decomposing schematic representation of the present invention
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration:
The LED illumination lamp that has hollow out passage radiator like Fig. 1, shown in 2; Said illuminating lamp by set gradually lamp holder 1, radiating seat 2; Lamp body 3 is formed; Said radiating seat 2 is provided with the cavity 21 of ring-type hollow out, and cavity 21 is provided with lamp holder opening 211, lamp body opening 212 respectively at the outside and the lamp body bottom end of lamp holder end.
Radiating seat 2 increases setting gradually to lamp body 3 direction sizes; Lamp body opening 212 is that the standard-sized sheet of ring-type is decontroled mouth; The rectangular opening that said lamp holder opening 211 is uniformly distributed with for the border; Make like this gas flow flow direction from cavity 21 to lamp holder opening 211 again to the passage in the external world shrink earlier, further expansion, form the Rafael nozzle effect, quicken gas flow.
The fuisw rib that axial direction is set 213 of cavity 21, the direction that fuisw rib 213 guiding gases make progress vertically flows, and prevents gas turbulent flow in cavity 21, influences the speed of the convection current of gas.
The corresponding setting with the middle position of lamp holder opening 211 of fuisw rib 213 can increase extraradial radiating surface.
The illuminating lamp of radiating seat 2 of the present invention, radiating seat 2 are provided with the cavity 21 of ring-type hollow out, and cavity 21 is provided with lamp holder opening 211, lamp body opening 212 respectively at the outside and the lamp body bottom end of lamp holder end; During installation, the general vertical installation of LED illumination lamp is when lamp body 3 work; On the heat heat loss through conduction seat 2 of lamp body 3; Under the situation that the air that cavity is 21 li is heated, can upwards flow, from the upwards outflow of lamp holder opening 211 of lamp holder end; Cold air gets into from lamp body opening 212 and replenishes; Lamp holder opening 211, cavity 21, lamp body opening 212 forms the gas flow of a circulation like this, forms " stack effect ", forms the strong heat loss through convection of radiating seat 2; The gas that upwards flows of lamp holder opening 211 gas that drives radiating seat 2 outer walls 215 upwards flows in addition, quickens the heat loss through convection (arrow as shown in Figure 1 is the gas flow direction) of outer wall 215; Radiating seat 2 can dispel the heat with transmission, convection current, radiation; Good heat dissipation effect; The heat that LED illumination lamp lamp body 3 is produced is in time led away and is scattered, and ensures the operate as normal of LED illumination lamp, prolongs the service life of LED illumination lamp.
The above embodiment; It is preferred embodiments of the present invention; Be not to limit practical range of the present invention,, all should be included in the patent claim of the present invention so all equivalences of doing according to the described structure of claim of the present invention, characteristic and principle change or modify.
