Description
Technical field
The present invention relates to lighting device, is a kind of LED lamp heat radiation light distribution structure.
Background technology
The LED light fixture has energy-saving and environmental protection, long-life advantage as current a kind of new type light source, and along with continuous advancement in technology, existing LED light fixture is ripe all the more, substitutes traditional lighting gradually, becomes a progressive important symbol of epoch.But the LED light fixture needs to install corresponding radiator structure because its photo-thermal is bigger, thereby prolongs the service life of LED light fixture.Through the test shows high-power LED lamp, when junction temperature was 74 ℃, the light output attenuatoin was 2 years to 50% required time, and junction temperature is when being 63 ℃, and this time promptly is increased to 6 years, and visible junction temperature is very huge to the influence in LED service life.
Summary of the invention
For overcoming above-mentioned deficiency, the objective of the invention is provides a kind of LED lamp heat radiation light distribution structure to this area, make its solve existing like product radiator structure be provided with not good enough, cost is higher, luminous intensity distribution is owed rational technical problem.Its objective is and realize through following technical scheme.
Organization plan one of the present invention: a kind of LED lamp heat radiation light distribution structure; This heat radiation light distribution structure comprises ventilative light distributing cap, convective cover, radiator, radiating core; Radiator constitutes sun fancy centrosymmetric structure by skeleton and fin; Radiator places in the convective cover, forms air chamber between the two adjacent fins in the radiator, and convective cover one end connects ventilative light distributing cap; Its structural feature is the built-in radiating core of said radiator; The radiator inwall closely contacts with the radiating core outer wall; Said radiating core is provided with the center radiating tube that places the radiating core shaft core position; And the axial radiating tube that is circumferential distribution with respect to the axle center of said radiating core; Center radiating tube one end and axially radiating tube one end and the one end conducting of said radiating core, said radiating core radially are provided with and are communicated with the said center radiating tube and the axial radially radiating tube of radiating tube, and said radiator is provided with the said air chamber of direct connection, center radiating tube, axial radiating tube, the louvre of radiating tube radially.Radiator adopts sun fancy structure; Cost is lower; Radiating effect is better; And radiator is provided with directly and said center radiating tube, axially radiating tube, the louvre that communicates of radiating tube radially, makes radially radiating tube, axial radiating tube, the conducting of center radiating tube formation windstream in air chamber and the radiating core of radiator, reaches the purpose of Homogeneouslly-radiating.
Fin number in the said radiator between the two adjacent skeletons is an even number; Constitute the said air chamber of odd number by the even number fin; Said louvre is corresponding with the air chamber at the said air chamber of odd number center, and said louvre and said radially radiating tube are corresponding to same center line.The purpose of said structure setting is: make radially radiating tube in the radiating core of the air chamber of radiator, axially the distance of radiating tube, center radiating tube is for the shortest, distance is short more, gas-flow resistance is more little, it is good more that air-flow exchanges smoothness.Said axial radiating tube, radially radiating tube is the center symmetry with respect to the axle center of said radiating core and distributes along radian such as circumferential; Said louvre is a center symmetry and along circumferentially waiting radian distribution, this structure purpose is a Homogeneouslly-radiating with respect to the axle center of said radiator.
Said radiating core constitutes radially radiating tube group along the radially radiating tube that circumferentially waits radian to distribute, along 1～2 group of said radially radiating tube group that is axially arranged with of said radiating core.Why be provided with 1～2 group radially the radiating tube group get final product, its reason be too much radially radiating tube group is set on the contrary can be too much because of the air-flow interchange channel, cause airflow lifting force not enough, can't form air fast and flow and to take away enough heats.
