Abstract

The utility model discloses an aluminum radiating structural piece of an LED (light emitting diode) lamp, which comprises a wall cylinder, an inner surface of the wall cylinder and an outer surface of the wall cylinder, wherein both the inner surface and the outer surface are convex-concave through oxidizing treatment. With the adoption of the aluminum radiating structural piece, the temperature of the LED lamp is effectively lowered and the service life of the LED lamp is prolonged.

Description

A kind of aluminum radiator structure spare of LED lamp

Technical field

The utility model relates to the LED lighting engineering, relates 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 because luminous efficiency is high, 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, and 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; Great amount of heat can not be distributed 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.

The utility model content

The utility model purpose: the purpose of the utility model is to overcome the shortcoming of prior art, and 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.

Technical scheme: the aluminum radiator structure spare of the described a kind of LED lamp of the utility model, comprise the inner surface and the outer surface of wall tube and said wall tube, said inner surface and outer surface be through melanism handle concavo-convex.

Further, said melanism is treated to through the anodic oxidation processing of turning black.

The preparation method of the aluminum radiator structure spare of LED lamp according to the invention comprises 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 utility model 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 said LED lamp is polished than before, the emissivity of the outer surface of coarse blackout equally also increases a lot.Said 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 sketch map of LED lamp in the prior art;

Fig. 2 is the aluminum radiator structure spare sketch map of the disclosed LED lamp of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.

As shown in Figure 1: a kind of aluminum radiator structure spare of LED lamp, comprise the inner surface 2 and outer surface 3 of wall tube 1 and said wall tube 1, said inner surface 2 and outer surface 3 be through melanism handle concavo-convex.Said melanism is treated to through the anodic oxidation processing of turning black.

The preparation method of the aluminum radiator structure spare of the said LED lamp of the utility model is:

(1) inner surface 2 with the aluminum radiator structure spare wall tube 1 of LED lamp is processed into rough rough surface with outer surface 3;

(2) with coarse inner surface 2 and outer surface 3 through the anodic oxidation processing of turning black.

According to the method for the utility model, 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 stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.

Claims

1. the aluminum radiator structure spare of a LED lamp comprises it is characterized in that the inner surface (2) and the outer surface (3) of wall tube (1) and said wall tube (1): said inner surface (2) and outer surface (3) be through melanism handle concavo-convex.
