Description
Technical Field
The invention relates to the field of electronic product manufacturing, in particular to a light guide cover of an electronic indicator light.
Background
Many electronic devices are known to illuminate an indicator light during operation to display information such as operating status and operating mode for users to refer to. For electronic devices which are easy to be affected with damp in the use environment, such as intelligent bathroom controllers, a glue pouring process is usually adopted, namely, a layer of glue is covered on the periphery of a circuit board and on-board components to achieve the purpose of preventing the circuit board from being affected with water and damp.
However, in the process of filling the circuit board with the glue, when a plurality of electronic patch indicator lamps are arranged side by side in series, the glue filled is transparent, so that when one indicator lamp is turned on, the light emitted by the indicator lamp can be refracted to the position of the adjacent indicator lamp through the transparent glue, so that the adjacent indicator lamp is not turned on, but the indication mark on the housing is easily regarded as a lighting state by a user due to light leakage, thereby generating misunderstanding in operation and use.
Therefore, there is a need for an improved solution to the light leakage of electronic indicator lamps, especially the light leakage of electronic indicator lamps in the process of filling glue into circuit boards.
Disclosure of Invention
The invention provides a light guide cover of an electronic indicator light, which aims to solve the problem of light leakage of the electronic indicator light, in particular to the problem of light leakage of a patch electronic indicator light in a circuit board glue filling process.
The invention provides a light guide cover of an electronic indicator light. The light guide cover is integrated into one piece, specifically contains: 1) and a circular light guide cylinder, wherein a light outlet is arranged above the circular light guide cylinder and points to the corresponding indication mark on the shell. 2) Circular light guide tube below is connected with one and possesses the concentric circular pilot lamp cover to the open-ended, and circular pilot lamp cover diameter is greater than the light guide tube to be greater than the diameter or the width of paster electronic indicator. The opposite openings on the wall of the circular indicator light cover are used for allowing the glue to flow into and cover the electronic indicator light; 3) the circular indicating lamp shade is connected with the light guide cylinder; 4) two round light guide cover legs are arranged on the outer side of the round indicator light cover. The two light guide cover legs are perpendicular to the direction of the opposite openings on the wall of the circular indicator light cover. The leg of the light guide cover is provided with an outward L-shaped protrusion and an elastic force, and is used for being embedded into a fixing bayonet on the circuit board to play a fixing role. The height of the light guide cover leg is slightly larger than the thickness of the circuit board. 5) The light guide cover is made of non-transparent engineering plastic.
Optionally, the connection of light guide tube and circular indicator light cover is an oblique connection on the section, and the both ends of connection are light guide tube top outward flange and circular indicator light cover top outward flange respectively.
Optionally, the connection between the light guide tube and the circular indicator light cover is a vertical connection on the cross section, but the connection part is at a 45-degree cut angle.
Optionally, the height of the leg of the light guide mask is 0.2mm greater than the thickness of the circuit board.
Optionally, the diameter of the inner cavity of the light guide cylindrical column is 0.5mm larger than the diameter or width of the patch LED indicator lamp.
Optionally, the width of the outward L-shaped protrusion at the bottom of the round light guide cover leg is 0.5 mm.
When using this electronic indicator light guide cover, need to reserve the fixed bayonet socket with light guide cover foot column interval looks adaptation around continuous paster LED pilot lamp on the circuit board. In order to avoid light leakage, the arrangement of the bayonets of the adjacent light guide covers needs to avoid that the circular indicator light covers on the light guide covers are aligned with the openings. Two light guide cover legs of the light guide cover are embedded into the fixing bayonets, so that the patch electronic indicator lamp is located in the inner cavity of the circular indicator lamp cover. When glue is poured, the glue flows into the opening of the circular indicating lamp cover and covers the indicating lamp. Because the light guide cover is made of non-transparent engineering plastic materials, light emitted after adjacent electronic indicating lamps are lightened is guided by the light guide cylinder to emit to the indicating mark position on the upper shell, and the light is isolated by the non-transparent light guide cover in the horizontal direction, so that the light leakage prevention effect is achieved.
The light guide cover has the advantages that the light guide cover is simple in structure and convenient to use, has a good light isolation effect on adjacent patch indicating lamps, can support glue to cover the electronic indicating lamps particularly under the glue filling condition, and meanwhile effectively prevents the light leakage phenomenon.
