Abstract

The invention discloses an LED lamp which comprises a lamp cap, a center connecting shaft matrix and an LED chip, wherein thin-plate radiating fins with overlapped equal parts are transversely arranged on the center connecting shaft matrix; the upper end of the center connecting shaft matrix is connected with the lamp cap; the lower end of the center connecting shaft matrix is connected with a light gathering cup; a radiating substrate is installed in the light gathering cup; the LED chip is fixed to the radiating substrate; and a wire perforation is formed in the interior of the center connecting shaft matrix and supplied for an LED chip connecting wire to pass through to be in contact with a power supply in the lamp cap. With the adoption of the thin-plate radiating fins which are provided with overlapped equal parts, the radiating area can be increased without adding the size of a using space, so that the LED lamp has the advantages of high heat conduction speed, large radiating area, high heat capacity, light weight, long service life, beautiful appearance and the like.

Description

LED
Technical field
The present invention relates to technical field of lighting fixtures, more specifically relate to LED.
Background technology
LED is owing to having the advantages such as the life-span is long, efficiency is high, radiationless, and dark liking by users, LED volume is more and more less, and the following LED chip heat produced is also increasing.Existing LED generally comprises radiator, globe holder and LED chip, and described radiator one end is lamp holder, other end fixed L ED chip and lampshade.But, the heat dispersion of LED is very crucial, too high temperature can cause LED job insecurity, even shorten the life-span, the cast aluminium lamp housing radiator that prior art uses cannot meet the requirement of use, as the transmission speed of cast aluminium lamp housing radiator and area of dissipation inadequate, the volume that heat dissipation capacity need increase radiator be met, and the volume of radiator is subject to the restriction of usage space.
Summary of the invention
In order to solve the problem, the invention provides a kind of good heat dissipation effect, the simple LED of structure.
According to an aspect of the present invention, provide LED, it comprises lamp holder, center connecting axle matrix and LED chip, center connecting axle matrix is horizontally arranged with the thin plate radiating fin of equal portion overlap, the upper end of center connecting axle matrix connects lamp holder, the lower end of center connecting axle matrix is connected with prefocus cup, in prefocus cup, heat-radiating substrate is installed, LED chip is fixed on heat-radiating substrate, be provided with in the connecting axle matrix of center wire perforation for LED chip connecting line by with the electrical power contacts in lamp holder.
In some embodiments, center connecting axle matrix is cuboid, the surrounding of center connecting axle matrix is equipped with installation groove, install in groove and be provided with salient point, thin plate radiating fin is provided with the installing hole corresponding with salient point, thin plate radiating fin is installed in the installation groove of center connecting axle matrix, and thin plate radiating fin and center connecting axle substrate are installed and adopted interference fit.
In some embodiments, the thin plate radiating fin of horizontally set equal portion overlap on the connecting axle matrix of center, the center line of Shi Yi center connecting axle matrix is in being horizontally disposed with, and thin plate radiating fin reduces diameter from bottom to top gradually, forms integral LED lamp housing profile.
In some embodiments, integral LED lamp housing profile is trapezoidal.
In some embodiments, the bottom of prefocus cup is provided with lampshade.
Advantage of the present invention is: the situation being different from prior art LEDbulb lamp heat dispersion deficiency, the present invention adopts the thin plate radiating fin of equal portion overlap, do not need to increase usage space volume, just area of dissipation can be increased, the present invention has that heat-transfer rate is fast, area of dissipation is large, thermal capacity is high, quality is light, long service life, the advantages such as good looking appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of LED of the present invention;
Fig. 2 is the center connecting axle basal body structure schematic diagram of LED of the present invention;
Fig. 3 is the structural representation of one piece of thin plate radiating fin of LED of the present invention.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated.
As shown in Figures 1 to 3, the LED of an embodiment of the present invention, comprise lamp holder 1, center connecting axle matrix 2 and LED chip 3, center connecting axle matrix 2 is horizontally arranged with the thin plate radiating fin 4 of equal portion overlap, the upper end of center connecting axle matrix 2 connects lamp holder 1, the lower end of center connecting axle matrix 2 is connected with prefocus cup 5, heat-radiating substrate 6 is installed in prefocus cup 5, LED chip 3 is fixed on heat-radiating substrate 6, be provided with in center connecting axle matrix 2 wire perforation 21 for LED chip 3 connecting line by with the electrical power contacts in lamp holder 1, the bottom of prefocus cup 5 is provided with lampshade 8.
Center connecting axle matrix 2 is cuboid, and the surrounding of center connecting axle matrix 2 is equipped with installs groove 22, installs in groove 22 and is provided with salient point 23.Thin plate radiating fin 4 is provided with the installing hole 41 corresponding with salient point 23, and thin plate radiating fin 4 is installed in the installation groove 22 of center connecting axle matrix 2, and thin plate radiating fin 4 and center connecting axle substrate 2 are installed and adopted interference fit.
On center connecting axle matrix 2, the center line of thin plate radiating fin 4, the Shi Yi center connecting axle matrix 2 of horizontally set equal portion overlap is in being horizontally disposed with, and thin plate radiating fin 4 reduces diameter from bottom to top gradually, forms integral LED lamp housing profile 7.In the present embodiment, integral LED lamp housing profile 7 is trapezoidal.Because center connecting axle matrix 2 adopts cuboid, be divided into four pieces for the ease of installing thin plate radiating fin 4, circle thin plate radiating fin 4.In actual applications, integral LED lamp housing profile 7 can be processed into various shape as required, and outward appearance is as: cylindrical, cuboid, cup-shaped etc.
Be different from the situation of prior art LEDbulb lamp heat dispersion deficiency, the present invention adopts the thin plate radiating fin 4 of equal portion overlap, and not needing increases usage space volume, just can increase area of dissipation.The present invention has that heat-transfer rate is fast, area of dissipation is large, and thermal capacity is high, quality is light, long service life, the advantages such as good looking appearance.
Above-described is only some embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art, and under the prerequisite not departing from creation design of the present invention, can also make other distortion and improve, these all belong to protection scope of the present invention.
