Abstract

The utility model provides an integrated heat dissipation LED bulb, comprising a LED driver and a LED chip. The bulb is composed of a bulb holder, a bulb holder connection body, a plurality of radiating fins, a fixed shaft of radiating fin combination, an LED base plate fixed part, an LED base plate, a radiating fin fixed ring and a lampshade. The utility model is characterized in that the LED chip is disposed on the LED base plate and is tightly integrated with the LED base plate fixed part into one piece and is contained in a hole which is closely matched with the fixed shaft of radiating fin combination; the plurality of radiating fins are inserted along the edge dental groove of the fixed shaft of radiating fin combination; the upper and lower end are respectively provided with the bulb holder connection body and the radiating fin fixed ring, and a radial type structure is formed. The utility model is advantageous in that as a heat dissipation structure is changed into a combined installation structure of single radiating fin, thereby the heat generated by LED chips in energization on the LED base plate can be effectively absorbed and conducted, and the heat can be rapidly cooled down and dispersed after passing through the radiating fin; LED bulb is protected and the service life is prolonged; producing cost is reduced and material is saved.

Description

A kind of combined type heat dissipation LED bulb

Technical field

The utility model belongs to the houselights technical field, relates to a kind of LED lamp, is specifically related to a kind of combined type heat dissipation LED bulb.

Background technology

LED is as a kind of new luminescent device, to have a volume little because of it, power consumption is low, and it is in the light fixture of light source that long advantage of life-span is applied to LED, and these light fixtures only are the peripheral sheathed lampshades at LED, the fin of LED lamp is one-body molded with lamp body, utilize secondary operations to go out external form, its section bar material utilization rate is low, the cost height, radiating effect is bad, has shortened the service life of LED light fixture greatly.

Summary of the invention

The purpose of this utility model provides a kind of combined type heat dissipation LED bulb structure; overcome the design shortcoming of traditional LED bulb; the combination of one chip fin is installed as one; absorb heat by the LED substrate heat conduction that be equipped with lamp body inside; the heat that absorbs is delivered on fin combination fixture, the one chip fin through LED substrate fixture again; realize that fast cooling has overcome the heat conduction of existing LED street lamp, the slow shortcoming of heat radiation; play protection LED light fixture; solve the problems referred to above that prior art exists, prolonged the service life of LED bulb.

The technical scheme that the utility model adopted is, a kind of combined type heat dissipation LED bulb, comprise led driver and led chip, this bulb is successively by lamp holder, the lamp holder connector, several cooling fins, fin combination fixed axis, LED substrate fixture, the LED substrate, fin retainer ring and lampshade constitute, described led chip is arranged on the LED substrate and closely connects as one with LED substrate fixture, and be contained in the hole with fin combination fixed axis close-fitting, described several cooling fins is inserted along fin combination fixed axis outer rim roller seating space, and the seam that is provided with of two ends is fixed into radial structure with lamp holder connector and fin retainer ring with its combination up and down.

Combined type heat dissipation LED bulb described in the utility model, its feature also be,

Also evenly be provided with some air vents on the described fin.

The utility model combined type heat dissipation LED bulb; to have now with the integrated heat abstractor of LED lamp and make the one chip combining structure into; one chip is the several cooling fins of radial arrangement; more effectively absorb and conduct the heat that is arranged at generation when led chip is switched on the LED substrate; realize the fast cooling heat radiation through fin again; the effect of having played protection LED bulb and having prolonged its service life has also reduced the heat abstractor manufacturing cost simultaneously, has saved material greatly.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

A kind of combined type heat dissipation LED bulb, as depicted in figs. 1 and 2, comprise led driver and led chip 6, this bulb is successively by lamp holder 1, lamp holder connector 2, several cooling fins 3, fin combination fixed axis 4, LED substrate fixture 5, LED substrate 7, fin retainer ring 8 and lampshade 9 constitute, described led chip 6 is arranged on the LED substrate 7 and closely connects as one with LED substrate fixture 5, and be contained in the hole with fin combination fixed axis 4 close-fittings, described several cooling fins 3 is inserted along fin combination fixed axis 4 outer rim roller seating spaces, and the seam that is provided with of two ends is fixed into radial structure with lamp holder connector 2 and fin retainer ring 8 with its combination up and down.

The utility model combined type heat dissipation LED bulb, make the heat abstractor of global formation into one chip fin 3, by installing with 4 combinations of fin combination fixed axis, as shown in Figure 3, and be fixed into its combination radial through lamp holder connector 2 and fin retainer ring 8, the heat that the led chip 6 of LED bulb produces when switching on makes up fixed axis 4 through

LED substrate

7 and 5 conduction of LED substrate fixture to fin, and the connected radial fin 3 of process is derived again, realizes cooling; Also evenly be provided with some air vents 10 on the fin 3, can more effectively realize ventilation and heat, fast cooling.

The one chip fin combination mounting structure of the utility model combined type heat dissipation LED bulb; the effect of having played effective protection LED bulb and having prolonged its service life; change the radiator structure of global formation into the one chip package assembly; optimized design; simplified manufacturing technique; reduced the heat abstractor manufacturing cost, saved material greatly, the LED bulb of a novelty is provided simultaneously.

Above-mentioned embodiment is an example of the present utility model; not enforcement and the interest field that is used for limiting utility model; all equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
