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.

Among the figure, 1. lamp holder, 2. lamp holder connector, 3. fin, 4. fin combination fixed axis, 5.LED substrate fixture, 6.LED chip, 7.LED substrate, 8. fin retainer ring, 9. lampshade, 10. air vent.
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.
