Abstract

The invention discloses a light-emitting diode (LED) drive power supply which comprises a shell body, a PCBA component arranged in the shell body and a wire which is led out from the shell body to the outside of the shell body. Two ends of the shell body form openings and respectively provided with a first end cover and a second end cover. Potting adhesive is poured into two ends in the shell body. A hollow interlayer without potting adhesive is reserved between the potting adhesive at two ends. The invention further discloses a pouring method of the LED drive power supply. The pouring method of the LED drive power supply includes the following steps. Firstly, a first end of the shell body is sealed, secondly, the potting adhesive is poured for the first time and thirdly, after the potting adhesive poured for the first time is solidified, second pouring is performed and a second end of the shell body is sealed. Fourthly, the shell body is inverted. The potting adhesive is poured into the two ends in the shell body for two times and the hollow interlayer is reserved in the middle of the shell body, production technology is simple, good airtight performance is achieved, potting adhesive consumption is reduced, the whole weight of the drive power supply is reduced, manufacturing cost is reduced and meanwhile, tensile strength of the wire is improved and forced detachment is prevented.

Description

technical field [0001] The invention relates to a power supply, in particular to an LED driving power supply and a glue filling method thereof. Background technique [0002] As people's awareness of energy saving continues to increase, the trend of LED lamps replacing traditional lamps is becoming more and more obvious. As an important link in the LED industry chain, LED drive power has been widely used. At present, there are many types of LED drive power supplies on the market, with different structures and performances. For example, the Chinese utility model patent with the patent number ZL201120361554.6 (authorized announcement number CN202328020U) discloses "A LED Drive Power Supply". It includes a housing and a power control circuit located in the housing. The housing is mainly composed of a body, a baffle and a cover. The inner side of the baffle is provided with fixing pins and raised parts, and the two ends of the body are provided with installation grooves. , the f...
