Description

A kind of LED of high rate of heat dissipation
technical field:
The utility model belongs to LED field, particularly relates to a kind of LED of high rate of heat dissipation.
background technology:
LED, as lighting source, has luminous efficiency high, photochromic many, volume is little, the advantage of safety and environmental protection, along with the development of LED technology, LED obtains applying more and more widely at lighting field, and LED energy-saving illumination becomes common recognition in industry by progressively substituting conventional illumination sources.
LED is as lighting source, and operationally, a part of power output is converted into heat by conduction to LED lamp bead, if do not take cooling measure, the heat of accumulation will cause the temperature of LED chip too high, thus will affect luminous efficiency and the life-span of LED light fixture.And the number of drawbacks such as in prior art, the radiator structure heaviness of LED light fixture is single, light fixture is poor for applicability, light-emitting area is single, integrated IP dustproof and waterproof rank difference.
utility model content:
The utility model overcomes the deficiency that prior art exists, and solves prior art Problems existing, aims to provide a kind of structure simple, installs reliable and stable, is widely used and the LED of the good a kind of high rate of heat dissipation of heat dispersion.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LED of high rate of heat dissipation, comprise radiating seat, lamp holder, LED lamp bead, LED circuit and lampshade, radiating seat entirety is inversed taper platform shape, radiating seat comprises stationary base mount, the lateral surface of described stationary base mount is provided with multiple radiating fin, described radiating fin offers multiple passage, described lamp holder is used for being connected with external socket, lamp holder is fixedly connected with the top of stationary base mount, LED lamp bead is arranged on the side of stationary base mount away from lamp holder, described LED circuit to be arranged in stationary base mount and to be electrically connected with LED lamp bead and lamp holder, described lampshade is fixedly connected with for sealing LED lamp pearl with the bottom of stationary base mount.
Further, described lampshade is connected with the base clamping of stationary base mount, the bottom of stationary base mount is provided with annular groove, and the top of lampshade is provided with the annular boss adapted with annular groove, and lampshade is fixedly connected with stationary base mount with annular groove clamping by annular boss.
Further, the side that described stationary base mount and LED lamp bead are fixed is provided with heat transfer piece.
Further, described radiating fin and the one-body molded setting of stationary base mount.
Further, described radiating fin outer surface has heat radiation paint.
The utility model compared with prior art has following beneficial effect: the utility model is by adopting special heat radiation seat structure, the heat that LED lamp bead produces is passed to stationary base mount by heat transfer piece, stationary base mount by radiating fin by heat rapid divergence in air, air vent is increased in addition on radiating fin, add the contact area of radiating fin and air, improve the radiating efficiency of cooling base further.Avoid LED lamp bead temperature too high, thus affect luminous efficiency and the service life of LED lamp bead.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described in more detail
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of radiating seat.
In figure: 1 is radiating seat, 2 is lamp holder, and 3 is LED lamp bead, and 4 is LED circuit, and 5 is lampshade, and 6 is stationary base mount, and 7 is radiating fin, and 8 is passage, and 9 is annular groove, and 10 is annular boss, and 11 is heat transfer piece.
detailed description of the invention:
As Figure 1-Figure 2, a kind of LED of high rate of heat dissipation, comprise radiating seat 1, lamp holder 2, LED lamp bead 3, LED circuit 4 and lampshade 5, radiating seat 1 entirety is inversed taper platform shape, radiating seat 1 can adopt thermal conductivity and the metal material such as the good copper of thermal diffusivity or aluminium to make, but because copper density is high, price, aluminum is adopted to do so general, particularly, radiating seat 1 comprises stationary base mount 6, the lateral surface of described stationary base mount 6 is provided with multiple radiating fin 7, described radiating fin 7 and the one-body molded setting of stationary base mount 6, the fixed seat structure intensity of one-body molded setting is high, be convenient to mounted LED lamp bulb 3 and LED circuit 4, radiating fin 7 offers multiple passage 8.
Described lamp holder 2 is for being connected with external socket, lamp holder 2 is fixedly connected with the top of stationary base mount 6, LED lamp bead 3 is fixed by screw in the side of stationary base mount 6 away from lamp holder 2, bolted connects can make LED lamp bead 3 and stationary base mount 6 good contact, the heat that LED lamp bead 3 can be produced is transmitted on stationary base mount 6 fast, and the side that described stationary base mount 6 is fixed with LED lamp bead 3 is provided with heat transfer piece 11.Described LED circuit 4 to be arranged in stationary base mount 6 and to be electrically connected with LED lamp bead 3 and lamp holder 2, and described lampshade 5 is fixedly connected with for sealing LED lamp pearl 3 with the bottom of stationary base mount 6.
