The utility model discloses the technical problem that solve is realized through following technical scheme:

the utility model provides a small LED light source capable of replacing bulb lamps, which comprises a lamp board PCB board welded with LED lamp beads, screws, an inner grinding PC lens, a silica gel sealing ring, a cold forging heat dissipation main body, a mounting bracket and a waterproof silica gel plug; the lamp panel PCB and the mounting bracket are respectively fixed on the cold forging heat dissipation main body through screws, the silica gel sealing ring is placed in a groove of the inner frosted PC lens, the waterproof silica gel plug is plugged into a through hole of the cold forging heat dissipation main body through self compressibility, and the screws fix the silica gel sealing ring and the PC lens on the cold forging heat dissipation main body through corresponding hole sites.

Preferably, the inner frosted PC lens is frosted with an inner lens layer.

Preferably, the waterproof silica gel plug is pushed into the bottom of the cylindrical through hole, and pouring sealant is injected into a section of space on the upper part of the cylindrical through hole to ensure the safety sealing of the electric cavity.

Preferably, the lamp panel PCB board has 10 equipartition 3030 lamp pearls.

Preferably, the power line passes through the waterproof silicone plug and enters the interior of the PC lens.

The beneficial effects of the utility model reside in that, the LED light source adopts the silica gel circle sealed and sealed gluey double seal, and the sealed grade of light source reaches IP 66. The overall diameter of the light source is 58mm, and the light source is slightly smaller than that of an A19 bulb lamp, so that the use scene of the A19 bulb lamp can be completely replaced. Besides, the 3030 lamp bead with high luminous efficiency is adopted, the luminous efficiency of the whole lamp is larger than 110LM/W, and the luminous efficiency of the whole lamp is higher and more energy-saving. The utility model discloses can adjust lamps and lanterns power according to the engineering needs, the range of application is wider.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Fig. 1 is an overall appearance of a small LED light source of the replaceable bulb lamp of the present embodiment. The composition of the LED light source will be mainly described with reference to the structure of the small LED light source of the replaceable bulb lamp shown in fig. 2. This LED light source comprises lamp plate PCB board 3, screw 1, interior dull polish PC lens 2, silica gel sealing washer 4, cold forging heat dissipation main part 5, and installing support 6, waterproof silica gel stopper 7. 10 lamp pearls 3030 are evenly distributed on the surface of the lamp panel PCB board 3 in a welding mode, so that the heat dissipation is more reasonable. The lamp panel PCB 3 is fixed on the cold forging heat dissipation main body 5 through screws. The silica gel sealing ring 4 is placed in the groove of the inner frosted PC lens 2. The mounting bracket 6 is fixed on the cold forging heat dissipation main body 5 by screws. The screw 1 fixes the silica gel sealing ring 4 and the PC lens 2 on the cold forging heat dissipation main body 5 through corresponding hole positions.

Fig. 3 is a structural diagram of an inner frosted PC lens of the small LED light source of the replaceable bulb lamp according to the present embodiment. Because the utility model discloses LED lamps and lanterns whole size is less, and the LED chip is nearer from the PC lens inward flange, and bright spot facula influence illuminating effect can appear in some use scenes. To eliminate flare, this embodiment uses a frosted PC lens 2 with a lens inner frosted 2-1.

Fig. 4 is a structural view of a cold forging heat dissipation main body of the small LED light source of the replaceable bulb lamp according to the present embodiment. The waterproof silica gel plug 7 is plugged into the cylindrical through hole 5-1 of the cold forging heat dissipation main body 5 by utilizing the compressibility of the waterproof silica gel plug. Because the silica gel plug is not enough to prevent water vapor from entering the electric cavity from the cylindrical through hole 5-1 only by means of self elasticity, the waterproof silica gel plug 7 is pushed into the bottom of the cylindrical through hole 5-1, and pouring sealant is injected into a section of space on the upper part of the silica gel plug to ensure the safety sealing of the electric cavity. The power cord passes through a waterproof silicone plug 7 into the interior of the PC lens 2.
