In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a slim SMD LED charactron, includes the PCB board, the welding of PCB board up end has the LED chip through the soldering, the PCB board outside is provided with the set casing, set casing inner wall fixedly connected with rubber pad, the fixed support of the equal fixedly connected with in set casing inner wall four corners position, the terminal surface pastes tightly in fixed support upper end under the PCB board, the reflection lid is installed to PCB board upper end, the reflection chamber has been seted up to the terminal surface under the reflection lid, reflection chamber up end is provided with the light trap, light trap and reflection chamber intercommunication, reflection chamber inner wall fixedly connected with reflecting plate.

Preferably, the welding of PCB board up end one side has the pin, pin outside fixedly connected with mounting, the mounting is made for the plastics material.

Preferably, the specific number of the LED chips is provided with a plurality of groups, and epoxy resin pouring sealant is sprayed on the outer sides of the LED chips.

Preferably, the PCB is a PCB with two sides coated with copper.

Preferably, the reflecting plate is obliquely fixed inside the reflecting cavity.

Compared with the prior art, the beneficial effects of the utility model are that: 1. the utility model discloses a be provided with set casing, rubber pad and fixed support, make it use of mutually supporting, set casing and rubber pad play fine protection and cushioning effect to PCB board and reflection lid, and fixed support has made things convenient for the installation of PCB board and set casing, moreover when the casting glue, only need at set casing and reflection lid junction carry on the casting glue can, reduced the quantity of casting glue.

2. The utility model discloses a be provided with reflection chamber, light trap and reflecting plate, the light that the LED chip sent carries out after the diffuse reflection in the reflection chamber and jets out from the light trap through the reflecting plate reflection at last to guarantee that the light-emitting of charactron is even.
