Abstract
The utility model relates to a radiating device of an LED bulb. The head and the root of the LED bulb are respectively provided with lamp body small holes, an aluminum substrate for placing an LED chip is provided with a substrate small hole, and the shape of the lamp body small hole is the same as that of the substrate small hole. By adopting the radiating device, the heat in the lamp head can be rapidly radiated through radiation and convection, and the radiating device has the characteristics of low cost and convenience in manufacture.
Description
Technical field
The utility model relates to LED bulb lamp field, relates in particular to a kind of LED bulb lamp heat abstractor.
Background technology
In the heat radiation of LED at present mainly is by having the aluminium heat transfer device, heat radiation by aluminium radiator fin is dispersed into the heat of led chip and LED driving power in the middle of the air, the heat that circuit board distributed of lamp holder inside then is enclosed in lamp holder inside, when the LED lamp is worked, the heat that drive circuit board and led chip send jointly will be dispersed into heat lamp holder inside continuously, internal heat can only be by LED aluminium radiating shell with outside radiations heat energy, the heat that the heat of LED also has driving power to send out except that itself generates heat, the temperature of the periphery of LED will further raise like this, and will be very unfavorable to operate as normal and the life-span of LED.The lamp holder inside of existing LED bulb lamp all is airtight, thereby influences distributing of heat.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of LED bulb lamp heat abstractor, this device can make distributing except that radiation of lamp holder internal heat, also has cross-ventilation, the heat of LED lamp holder inside can be shed as early as possible, have characteristics with low cost, that be convenient to produce.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of LED bulb lamp heat abstractor has lamp body aperture 3 at the lamp head 1 and the root 2 of LED bulb lamp, has substrate aperture 5 at the aluminium base 4 of placing led chip.
Described substrate aperture 5 is a kind of in circular hole, elliptical aperture or the square hole.
Described lamp body aperture 3 is a kind of in circular hole, elliptical aperture or the square hole.
Described lamp body aperture 3 is consistent with the pass of substrate aperture 5.
The utility model compared with prior art has the following advantages:
Make distributing except that radiation of lamp holder internal heat, also have cross-ventilation, like this, the heat of LED lamp holder inside can distribute quickly, thereby reduces the temperature rise of LED lamp holder inside effectively.
Description of drawings
Fig. 1 is the utility model lamp body schematic diagram.
Fig. 2 is this practical aluminium base schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in drawings, the utility model is a kind of LED bulb lamp heat abstractor, has lamp body aperture 3 at the lamp head 1 and the root 2 of LED bulb lamp, has substrate aperture 5 at the aluminium base 4 of placing led chip.Described lamp body aperture 3 all is a circular hole with substrate aperture 5.
Because the lamp body aperture 1 of LED bulb lamp and the substrate aperture 2 on the aluminium base can form cross-ventilation at the LED adstante febre, therefore the heat of lamp holder and aluminium base are distributed as early as possible.
Prove in the test, the concrete light fixture of actual measurement number money, before the perforate, the temperature of aluminium radiator is not 64 ℃, and after pressing this programme, the temperature of actual measurement aluminium radiator is 58 ℃, thus reduced the temperature of radiator effectively.
