The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The following describes a light module of the present invention, which includes:

the circuit board comprises an outer shell 1, wherein a circuit board 2 is installed in the outer shell 1, and an indicator lamp 3 is arranged in the circuit board 2; be equipped with the window that supplies optic fibre to pass through on the terminal surface of shell body 1, be equipped with optical fiber connector 6 and printing opacity piece 4 in the window, optic fibre 11's end passes behind the printing opacity piece 4 with optical fiber connector 6 is connected, printing opacity piece 4 supplies the light that pilot lamp 3 sent transmits out outside the shell body 1, just the area of printing opacity piece 4 printing opacity face on the shell is greater than the area of the light emitting area of pilot lamp 3. When the circuit board 2 works, the indicator light 3 on the circuit board 2 can send out an optical signal representing the working state of the circuit board, the optical signal sent by the indicator light 3 illuminates the light-transmitting piece 4 after passing through the light-transmitting piece 4, and because the area of the light-transmitting surface of the light-transmitting piece 4 on the shell is larger than that of the light-emitting surface of the indicator light 3, a user can more easily and directly know the working state of the optical module from a longer distance.

Further, a light guide part 5 for light transmission is connected between the light emitting surface of the indicator light 3 and the light transmission part 4; the light signal sent by the indicator light 3 is transmitted to the light-transmitting member 4 through the light-guiding member 5, so that the light signal sent by the indicator light 3 can be better transmitted to the light-transmitting member 4; the light guide 5 may be made of glass, transparent plastic, or other material with good light guiding performance.

In this embodiment, the fiber optic connector 6 is connected to a lens assembly 8 mounted on the circuit board 2 via a fiber core 7. The optical signal transmitted by the optical fiber is input into the circuit board 2 through the lens assembly 8, and the circuit board 2 converts the optical signal into an electrical signal.

In this embodiment, the outer casing 1 is made of a metal material, and the circuit board 2 is provided with a heat conducting adhesive, which is connected to the outer casing 1.

In this embodiment, the outer casing 1 is provided with heat dissipating ribs 9 protruding upward. The heat generated by the circuit board 2 in the working process is transmitted to the outer shell 1 made of metal material through the heat conducting glue, and the heat dissipation ribs 9 are arranged on the outer shell 1 and are beneficial to the heat dissipation of the optical module.

In this embodiment, the number of the indicator lights 3 arranged in the circuit board 2 is two or more, the number of the light guide members 5 is consistent with the number of the indicator lights 3, and the light guide members 5 correspond to the indicator lights 3 one by one.

The working state of the indicator light 3 of the invention on the circuit board 2 can be expressed in various ways, such as: the operating states of the circuit board 2 are distinguished by the difference of the light emitting colors or the difference of the frequencies of the light emitting flickers, which may be specifically: if in the normal operating condition, the pilot lamp 3 gives out the green light, and under the abnormal condition, the pilot lamp 3 gives out the red light; for another example, in a normal working state, the indicator light 3 is normally on, and in an abnormal state, the indicator light 3 continuously flickers; the specific expression is not particularly limited herein. And when adopting different colours to show circuit board 2's different operating condition, then it can install the lamp pearl of two different colours in circuit board 2, if: red and green, when the circuit board 2 is in a normal working state, the green lamp beads are started, and when the circuit board 2 is in an abnormal working state, the red lamp beads are started; the light signals emitted by different lamp beads are transmitted to the same light-transmitting part 4 through various corresponding light-guiding parts 5.

Referring to fig. 1 to 4, in order to better illustrate the optical module of the present invention, the following describes the optical module in detail with an embodiment, which specifically includes:

in this embodiment, the optical fiber connector 6 is inserted into and engaged with the optical fiber, and the light-transmitting member 4 is sleeved on an outer side surface of the optical fiber. Because the optical fiber is movably inserted on the optical fiber connecting piece 6, the optical module is convenient to replace.

In this embodiment, the light-transmitting member 4 is provided therein with a claw 12 for fastening to the outer side surface of the optical fiber. When the optical module is used, one tail end of an optical fiber is inserted into the window, so that the optical fiber connecting piece 6 is connected with the fiber core 7 in the optical fiber, and meanwhile, the clamping jaw 12 in the light-transmitting piece 4 clamps the outer side face of the optical fiber to prevent the optical fiber from falling off. Moreover, the light-transmitting member 4 is sleeved on the outer surface of the optical fiber, so that when the optical module works, the light signal generated by the indicator light 3 is transmitted to the light-transmitting member 4 in the window through the light-guiding member 5, and the light-transmitting member 4 is annularly arranged on the outer side surface of the optical fiber, so that an annular light signal can be formed on the outer side surface of the optical fiber, and the optical module can be identified by a user.

Referring to fig. 5 to 7, in order to better illustrate the optical module of the present invention, the following describes the optical module in detail with another embodiment, which specifically includes:

in this embodiment, the optical fiber connector 6 is fixedly connected to the optical fiber 11, and the light-transmitting member 4 is disposed outside the optical fiber connector 6. Because the optical fiber connector 6 is fixedly connected with the optical fiber 11, the optical fiber 11 cannot be separated from the optical module due to the action of external force, and the optical transmission effect is effectively ensured.

In this embodiment, a sheath 10 is sleeved on an outer side surface of the optical fiber 11, the sheath 10 is made of a transparent material, and the sheath 10 is connected with the light-transmitting member 4. When the optical module is in use, the indicator light 3 on the circuit board 2 sends an optical signal reflecting the working state of the circuit board 2, the optical signal is transmitted to the light-transmitting piece 4 through the light-guiding piece 5, and the sheath 10 is made of a transparent material and is connected with the light-transmitting piece 4; therefore, the light signal is emitted from the light-transmitting member 4 and then enters the sheath 10, which lights the sheath 10, thereby effectively enlarging the light-emitting area and facilitating the user to observe the light signal emitted from the indicator light 3.
