Description
Technical Field
The utility model relates to a radiator technical field, concretely relates to LED bulb lamp radiator.
Background
The LED bulb lamp is a product which is developed by applying a novel LED lighting source and improving the traditional bulb lamp, and has the following advantages compared with the traditional bulb lamp: energy saving, low carbon, long service life, good color rendering and high response speed. This is particularly important for structures where the power supply is mounted within the fixture, since the luminous efficiency of the LED decreases as the temperature of the LED increases, so heat dissipation from the LED is very important.
The radiator used by the existing LED bulb lamp is complex in structure and low in radiating efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to be not enough among the prior art, and provide a LED bulb lamp radiator, adopt this radiator can solve the slow problem of heat dissipation.
The purpose of the utility model is realized through the following technical scheme: the application provides a radiator for an LED bulb lamp, which comprises a circular aluminum substrate, wherein a plurality of radiating fins which are arranged at intervals and parallel to a vertical plane are sequentially arranged on the back surface of the aluminum substrate from left to right, and the distance between every two adjacent radiating fins is 3-5 mm; a circular vacant area for installing a fan is reserved in the middle of the back of the aluminum substrate; the end part of each radiating fin, which points to the edge of the aluminum base plate, is provided with an inclined surface for draining water.
Wherein, the radiating fin is prepared by aluminum alloy.
Wherein, the distance between two adjacent radiating fins is 3.5 mm.
Wherein, the middle part of aluminium base board is seted up a plurality of mounting holes that are used for installing the fan.
Wherein, the height of radiating fin is 30 mm.
Wherein, the outer surface of the radiating fin is coated with a graphite coating.
Wherein the thickness of the graphite coating is 0.5 mm.
The utility model has the advantages that: compared with the prior art, the radiator for the LED bulb lamp is simple in structure, the radiating fins are uniformly distributed in a parallel mode, the radiating channels in the single direction can be formed, radiating efficiency is improved, in addition, the radiating fins are provided with the inclined planes, water mist or water drops can be effectively guided to flow out conveniently, and the radiating fins can be prevented from being accumulated in dust.

Detailed Description
The invention will be further described with reference to the following examples.
The utility model discloses a specific implementation mode of radiator for LED bulb lamp, as shown in fig. 1, including circular shape aluminium base board 1, aluminium base board 1's the back has set gradually a plurality of intervals from a left side to the right side and has set up and with the parallel radiating fin 2 in vertical plane, and the distance between two adjacent radiating fin 2 is 3mm-5mm, and radiating fin 2's height is 30 mm. Preferably, the distance between two adjacent heat dissipation fins 2 is 3.5 mm. Compared with the prior art, the radiator of this embodiment simple structure, radiating fin 2 adopts parallel mode to carry out the equipartition, can form the radiating passage of unilateral, and the cooperation fan can carry out the heat dissipation of unilateral effectively.
In the present embodiment, in order to be mounted in cooperation with a lamp, a circular vacant region for mounting a fan is left in the middle of the back surface of the aluminum substrate 1, and a plurality of mounting holes 11 for mounting a fan are opened in the middle of the aluminum substrate 1.
In the present embodiment, the end of each heat dissipating fin 2 directed to the edge of the aluminum substrate 1 is provided with a slope 21 for water drainage. The radiating fins 2 are provided with the inclined surfaces 21, so that the guiding and flowing-out of water mist or water drops are effectively facilitated, and the dust accumulation of the radiating fins 2 can also be prevented.
In the present embodiment, in order to further improve the heat dissipation efficiency, the outer surface of the heat dissipation fin 2 is coated with a graphite coating, wherein the thickness of the graphite coating is 0.5 mm. It should be noted that the graphite coating is known in the art and is commercially available with good thermal conductivity.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
