Abstract
The invention discloses an aluminum radiating structural piece of a light emitting diode (LED) lamp, which comprises a wall barrel and an inner surface and an outer surface of the wall barrel, wherein the inner surface and the outer surface are concave-convex surfaces which are subjected to oxide treatment. By the device, the temperature of the LED lamp is effectively reduced and the service life of the LED lamp is prolonged. Simultaneously, the invention also discloses a manufacturing method of the aluminum radiating structural piece of the LED lamp.
Description
Technical field
The present invention relates to the LED lighting engineering, relate to the heat dissipation technology in the LED lighting engineering more specifically.
Background technology
Current under the background that the worry of global energy shortage raises once again, energy savings is the major issue that our present and even following long time all will face.At lighting field, semiconductor lighting since its energy-saving and environmental protection, characteristic such as high-end receive much concern.The LED illuminating lamp is owing to luminous efficiency height, energy-conservation, and the good effectiveness of colour developing is extensively popularized in the world.Because the LED of LED illuminating lamp pipe and power package are in an airtight areola, the heat that produces when the components and parts of LED and power supply are worked can not in time distribute, cause temperature in the lamp higher and influence life-span of LED lamp, this is a major defect that has the LED illuminating lamp now.
As shown in Figure 1, at present the structural member of LED lamp is for attractive in appearance, after be oxidized to silvery white, the slin emissivity of this processing is approximately 0.02 through polishing for inner surface and outer surface.Like this, the heat absorption capacity of inner surface is very poor, the heat-sinking capability of outer surface is also very little, though the thermal conductivity of aluminium is higher, but the integral heat sink ability of member also is not fine, a large amount of heats can not distribute rapidly in LED lamp inside, makes the interior temperature of lamp too high, causes the damage of the light decay and the power supply apparatus of led chip.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the shortcoming of prior art, a kind of temperature that can effectively reduce the LED lamp is provided, the aluminum radiator structure spare of the LED lamp in the service life of prolongation LED lamp.
Another object of the present invention is to provide the preparation method of the aluminum radiator structure spare of this LED lamp.
Technical scheme: the aluminum radiator structure spare of a kind of LED lamp of the present invention, comprise the inner surface and the outer surface of wall tube and described wall tube, described inner surface and outer surface be through melanism handle concavo-convex.
Further, described melanism is treated to through the anodic oxidation processing of turning black.
A kind of preparation method of aluminum radiator structure spare of LED lamp is characterized in that comprising the steps:
(1) inner surface and the outer surface with the aluminum radiator structure spare wall tube of LED lamp is processed into rough rough surface;
(2) with coarse inner surface and outer surface through the anodic oxidation processing of turning black.
Beneficial effect: the present invention compared with prior art, its beneficial effect is: high tens of times of the emissivity of the inner surface that the inner surface emissivity of the coarse blackout of the aluminum radiator structure spare of described LED lamp is polished than before, the emissivity of the outer surface of coarse blackout equally also increases a lot.Described device adopts aluminum, under the situation that does not cause heat-transfer rate, has increased the emissivity of surfaces externally and internally, thereby has significantly reduced the temperature of LED globe lamp, reduces the light decay of LED tube core and avoids the device failure of power supply, makes the energy-saving and environmental protection of LED lamp, longevity.
Description of drawings
Fig. 1 is the aluminum radiator structure spare schematic diagram of LED lamp in the prior art.
Fig. 2 is the aluminum radiator structure spare schematic diagram of LED lamp disclosed by the invention.
The specific embodiment
Below in conjunction with accompanying drawing, technical solution of the present invention is elaborated, but protection scope of the present invention is not limited to described embodiment.
As shown in Figure 1: a kind of aluminum radiator structure spare of LED lamp, comprise the inner surface 2 and the outer surface 3 of wall tube 1 and described wall tube 1, described inner surface 2 and outer surface 3 be through melanism handle concavo-convex.Described melanism is treated to through the anodic oxidation processing of turning black.
The preparation method of the aluminum radiator structure spare of LED lamp of the present invention is:
(1) inner surface 2 and the outer surface 3 with the aluminum radiator structure spare wall tube 1 of LED lamp is processed into rough rough surface;
(2) with coarse inner surface 2 and outer surface 3 through the anodic oxidation processing of turning black.
According to method of the present invention, after the coarse blackout processing of the surfaces externally and internally of aluminum radiator structure spare, the emissivity of aluminum radiator structure spare surfaces externally and internally can reach about 0.7, and untreated relatively slin emissivity improves tens times, more near black matrix.Like this, the inner surface absorbability of aluminum radiator structure spare has improved tens of times, and the heat-sinking capability of outer surface has also improved tens of times, and aluminum radiator structure spare integral heat sink ability has had significant rising, reduce the temperature in the LED lamp effectively, thereby prolong the life-span of LED illuminating lamp.
As mentioned above, although represented and explained the present invention that with reference to specific preferred embodiment it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite that does not break away from the claims definition, can make various variations in the form and details to it.
