Definitions
- the utility model relates to the field of decorative lamps, in particular to a novel beer-type lamp holder.
- Light strings are common lighting.
- the production process of the existing decorative lamp string of the beer-type lamp holder is generally as follows: The LED is connected to the wire and placed in the light-transmissive bulb, and then the lamp holder is molded at the tail of the light-transmissive bulb.
- the lamp holder covers the electrical connection point between the wire, the wire and the LED.
- the disclosed LED package includes the following production process: connecting the LED to the wire group, placing it in the cavity of the transparent cover, and molding the covered wire at the opening of the transparent cover.
- the beer-injected lamp caps produced according to this process have greatly improved the waterproof and insulating properties, but still have the following drawbacks and disadvantages:
- the injection lamp holder is made of hard plastic such as PP, and the coated wire It is a rubber with good flexibility.
- the inconsistency between hardness and ductility of the two causes inevitable gap between the injection lamp holder and the wire. In the long-term harsh outdoor environment, these voids may cause moisture to enter the lamp cap. Cause damage or even a safety incident.
- the purpose of the utility model is to provide a novel beer-type lamp holder, which fundamentally solves the problem that the injection molding compound is punched into the bulb and the waterproof performance is poor.
- An LED including a package body and a lamp foot
- a light-transmissive bulb having a cavity therein, the package body of the LED being placed in the cavity;
- sealing member mounted on the open end of the light-transmitting bulb for sealing a cavity, the sealing member being provided with a through hole matching the lamp pin of the LED, the lamp leg of the LED passing through the through hole
- the sealing member is partially accommodated inside the cavity of the light-transmitting bulb, and the resin is filled with resin between the lamp pin and the through hole;
- the lamp holder covers the tail portion of the light-transmitting bulb, a part of the wire, the electrical connection point between the lamp pin of the LED and the wire, and the portion of the sealing member exposed outside the bulb.
- the seal includes an insertion portion that is received inside the open end of the light transmissive bulb.
- the sealing member further includes a thrust portion protruding from the bottom end of the insertion portion and stopping at the outer edge of the open end of the light transmissive bulb.
- the seal is provided with a circular recess that surrounds a portion of the package of the LED.
- the package of the LED is closely attached to the sealing member
- the through hole is narrowed from the top to the bottom.
- a spacer is disposed between the lamp legs of the LED, and the spacer is located under the seal, and the spacer isolates the lamp pin and a part of the wire of the LED.
- the outer surface of the light transmissive bulb is provided with at least one annular groove, which is covered by the lamp holder.
- the resin is an epoxy resin or a silicone resin.
- the gap between the lamp post and the sealing member of the light-transmitting bulb is prevented from entering the cavity of the bulb during the injection molding process of the lamp holder, and is blocked.
- the blister and the burnt LED prevent the moisture entering from the gap between the wire and the lamp holder from further infiltrating into the blister cavity during long-term use, which greatly improves the waterproof performance of the lamp cap.
- Figure 1 is a schematic view of the lamp head of the present invention connected to a light string;
- Figure 2 is a perspective view of the utility model
- Figure 3 is a schematic longitudinal sectional view of the first embodiment of the present invention.
- FIG. 4 is a perspective view of an LED and a sealing member according to Embodiment 1 of the present invention.
- FIG. 5 is a schematic longitudinal sectional structural view of an LED and a sealing member according to Embodiment 1 of the present invention.
- Figure 6 is a perspective view of the LED and the sealing member of the second embodiment of the present invention.
- FIG. 7 is a schematic longitudinal sectional view of an LED and a sealing member according to Embodiment 2 of the present invention.
- the beer-type lamp cap of the present invention comprises a light-transmitting bulb 3 and a lamp holder 6, and the wire 2 is connected to a plurality of lamp caps to form a lamp string.
- the beer-type lamp cap of the first embodiment of the present invention comprises an LED 1 , a wire 2 electrically connected to the lamp pin 11 of the LED 1 , a light-transmitting bulb 3 with a cavity inside, and a light-transmissive bulb.
- the sealing member 4 of the sealed cavity at the open end of 3 passes through the injection molded lamp holder 6.
- the LED 1 includes a package body 12 and a lamp pin 11, and the package body 12 is housed in a cavity of the light-transmitting bulb 3.
- the seal 4 is provided with a through hole that matches the leg 11 of the LED 1.
- the sealing member 4 includes an insertion portion 41 and a thrust portion 42.
- the insertion portion 41 is received inside the open end of the light-transmitting bulb, and the thrust portion 42 protrudes from the bottom end of the insertion portion 41 and stops at the opening of the light-transmitting bulb 3.
- the package 12 of the LED is in close contact with the sealing member 4, and the lamp pin 11 is electrically connected to the wire 2 through the through hole.
- the socket 6 covers a portion of the wire, the electrical connection point 5 between the lamp pin 11 of the LED 1 and the wire 2, and the portion of the sealing member 4 that is exposed outside the bulb.
- the through hole of the sealing member 4 is narrowed from the top to the bottom, and there is a fine gap between the lamp pin 11 and the through hole.
- resin 7 can be applied to the lamp pins 11 or through holes in advance. The lamp foot 11 is then passed through the through hole.
- the resin 7 may be an epoxy resin or a silicone resin.
- a spacer 8 is disposed between the lamp legs 11, and the spacer 8 is located below the sealing member 4.
- the spacer 8 isolates the lamp pins 11 of the LED and a portion of the conductive wires.
- the outer surface of the light-transmitting bulb 3 is provided with an annular groove 9 which is covered with an annular groove 9 after injection molding, and is fixedly stuck between the two.
- the sealing member 4 is provided with a circular recess 43 which, when assembled with the sealing member, encloses a portion of the package 12 of the LED for better sealing.
- Other points include LED 1, lamp 11 and resin 7 which are substantially identical and will not be described here.
