In the prior art, the indicating lamp 31 mostly adopts an LED, and the light of the LED is strong, so that the LED cannot be directly arranged at the indicating window 13, and the indicating light-transmitting member 4 needs to be arranged at the indicating window 13 to reduce the light intensity and play a role of light-homogenizing; in addition, the indicator light assembly can generally indicate a plurality of colors, so a plurality of indicator lights 31 with different colors are required to be installed on the first circuit board 3, and the light of the indicator lights 31 can all irradiate the indication light-transmitting member 4, so the first circuit board 3 is generally installed on the back shell, a certain interval is left between the first circuit board 3 and the installation panel 1, the indicator lights 31 are installed on the surface of the first circuit board 3 facing the installation panel 1, and thus any indicator light 31 can irradiate the indication light-transmitting member 4 through the interval after being turned on. But the space occupied by the indicator assembly is significantly increased due to the presence of the spacing.

The back shell 2 and the back cover of the installation panel 1 are covered and fixedly connected with each other, and the connection mode between the two can be at least one of bonding, clamping and screw connection. Preferably a combination of snap and screw connections are used so that the back shell 2 can be detachably connected to the mounting panel 1.

Referring to fig. 5, the first reflector 21 and the second reflector 22 may be of a plate-like structure or other structures, preferably, of a plate-like structure, the inner side of the first reflector 21 and the inner side of the second reflector 22 are both flat surfaces and both face the first circuit board 3, or the inner side of the first reflector 21 and the inner side of the second reflector 22 are both respective front surfaces, because the first reflector 21 and the second reflector 22 are both located on the back side of the first circuit board 3, so that the inner sides of the first and second reflectors face the first circuit board 3 side, wherein the inner side of the first reflector 21 is a first reflective plane 201, the inner side of the second reflector 22 is a second reflective plane 202, the first reflective plane 201 specifically faces the indicator lamp 31, so that light emitted by the indicator lamp 31 can substantially all irradiate onto the first reflective plane 201, the first reflective plane has an angle with the mounting panel 1, and specifically, in a direction from the indicator 4 to the indicator lamp 31, the side of the first reflective plane 201 faces the mounting panel 1, so that light emitted by the indicator lamp 31 is inclined towards the side of the mounting panel 1, and the side of the indicator lamp 201 is inclined towards the side of the light transmitting panel 4; the second light reflecting plane 202 faces the indication light transmitting member 4, the second light reflecting plane 202 and the surface of the installation panel 1 are also provided with an angle, specifically, in the direction from the indication light transmitting member 4 to the indicator lamp 31, the second light reflecting plane 202 inclines to the side far away from the installation panel 1, in the thickness direction of the installation panel 1, the first light reflecting plane 201 and the second light reflecting plane 202 are at least partially overlapped, so that part of light reflected by the first light reflecting plane 201 can shine to the second light reflecting plane 202, and shine to the indication light transmitting member 4 through the reflection of the second light reflecting plane 202, so that the indication light transmitting member 4 can emit light outwards.

It should be emphasized that the light reflected by the first light reflecting plane 201 is emitted to one side of the light transmissive indicating member 4, because the light emitted by the indicator 31 has a certain divergence angle, a part of the light reflected by the first light reflecting plane 201 directly irradiates the light transmissive indicating member 4 (this part of the light is called a first light), a part of the light is reflected to the second light reflecting plane 202 and reflected to the light transmissive indicating member 4 via the second light reflecting plane 202 (this part of the light is called a second light), and the rest of the light is reflected to the first circuit board 3 or the mounting panel 1, and is reflected to the light transmissive member via multiple reflections of the first circuit board 3, the mounting panel 1 and the light reflective structure (this part of the light is called a third light); most of the light emitted from the indicator lamp 31 reaches the indicator light-transmitting member 4 along the paths of the first light and the second light, that is, most of the light emitted from the indicator lamp 31 can be reflected once or twice to irradiate the indicator light-transmitting member 4, so as to reduce the loss caused by the reflection of the light and ensure the brightness of the indicator light-transmitting member 4.

Further, an included angle between the first light reflecting plane 201 and the plane where the mounting panel 1 is located is preferably smaller than 45 °, so that after the light emitted by the indicator lamp 31 is reflected by the first light reflecting plane 201, most of the light irradiates the indicating light-transmitting member 4, the proportion that the light irradiates the indicating light-transmitting member 4 after being reflected once (the first light) is enlarged, and the brightness of the indicating light-transmitting member 4 is improved.

The angle between the first light reflecting plane 201 and the plane of the mounting panel 1 (hereinafter referred to as the first angle) may be 18 ° to 45 °, for example, 18 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, etc.

For example, the angle between the first light reflecting plane 201 and the plane of the mounting panel 1 is 20 °, and the indicator light 31 is directed toward the first light reflecting plane 201 along the normal direction of the mounting panel 1, and then directly directed toward the indicator light-transmitting member 4 on one side after being reflected by the first light reflecting plane 201.

Of course, the angle between the second light reflecting plane 202 and the plane of the mounting panel 1 (hereinafter referred to as the second angle) may be 30-60 °, for example, 30 °, 35 °, 40 °, 45 °, 50 °, 55 ° or 60 °, and the like, in the side-by-side direction, the size of the indicator lamp 31 is larger than the size of the light transmitting member 4 (the indicator lamps 31 are arranged side by side, as will be described later), and the second angle is larger than the first angle, so that the first light reflecting plane 201 covers a larger range than the second light reflecting plane 202 (the area of the projection of the first light reflecting plane 201 is larger than the area of the projection of the second light reflecting plane 202 in the plane of the mounting panel 1), and the second light reflecting plane 202 can reflect the light irradiated thereon to the light transmitting member 4.

In addition, the end of the first reflector 21 close to the indication light-transmitting member 4 and the end of the second reflector 22 close to the indication lamp 31 are connected to each other, so that the first reflective surface is connected to the second reflective surface, and an included angle is formed between the first reflective surface 201 and the second reflective surface 202, wherein the included angle is preferably an obtuse angle, so that in the thickness direction, the reflective structure is more flat, and the space occupied by the indication lamp assembly is reduced.

Through the arrangement, 70% -80% of the light emitted by the indicator lamp 31 can be the first light and the second light, so that the brightness of the indicating light-transmitting member 4 is ensured.

Moreover, the first reflective plane 201 and the second reflective plane 202 are both mirror surfaces, that is, after light irradiates on the two reflective planes, mirror reflection occurs, so as to reduce scattering loss of light, so that more light can irradiate on the position of the indication translucent member 4, thereby ensuring the brightness of the indication translucent member 4.

Preferably, referring to fig. 5, the indicator lamp 31 protrudes from the back surface of the first circuit board 3.

The light reflecting structure further comprises a first side plate 23, the first side plate 23 is parallel to the normal direction of the installation panel 1, one end of the first side plate 23 is connected to one end of the first reflection plate 21, which is far away from the second reflection plate 22, the other end of the first side plate 23 is abutted to the installation panel 1, and the indication lamp 31 is further far away from the installation panel 1 compared with one end of the first reflection plate 21, which is connected to the first side plate 23, in the normal direction.

The first side plate 23 is arranged, so that the first light reflecting plate 21 is abutted to the mounting panel 1 through the first side plate 23, that is, the distance between the first light reflecting plate 21 and the mounting panel 1 is increased; moreover, because the indicator lamp 31 protrudes from the back of the first circuit board 3, and one end of the first reflector 21 connected with the first side plate 23 is farther away from the installation panel 1 than the indicator lamp 31, so that any position on the first reflector 21 is farther away from the reflector panel than the indicator lamp 31, that is, when the back shell 2 is connected with the installation panel 1, the first reflector 21 cannot touch the protruding indicator lamp 31 at all, and the safety of the indicator lamp assembly in the assembling and disassembling process is improved.

Of course, the reflective structure may not include the aforementioned first side plate 23, and in this case, the end of the first reflective plate 21 away from the second reflective plate 22 abuts against the mounting panel 1.

Further, referring to fig. 4 and 6, the light reflecting structure further includes a second side plate 24 and a third side plate 25 which are oppositely disposed, the second side plate 24 and the third side plate 25 extend along a direction parallel to the normal direction and a side-by-side direction, the second side plate 24 and the third side plate 25 are respectively located at two sides of the indicator lamp 31 perpendicular to the side-by-side direction, and are connected with the first side plate 23, the first light reflecting plate 21 and the second light reflecting plate 22 and abut against the installation panel 1, and the first side plate 23, the second side plate 24, the third side plate 25, the first light reflecting plate 21, the second light reflecting plate 22 and the installation panel 1 jointly enclose a relatively closed space.

The light reflecting structure is composed of a first side plate 23, a second side plate 24, a third side plate 25, a first light reflecting plate 21 and a second light reflecting plate 22, so that a space surrounded by the light reflecting structure is only opened towards the front, when the back shell 2 is covered on the display panel, the back of the display panel basically seals the opening, so that a relatively closed space is formed, the indicator lamp 31 is located in the closed space, therefore, light emitted by the indicator lamp 31 can be reflected only in the closed space, so that more light can be irradiated to the indicating light-transmitting member 4, and the brightness of the indicating light-transmitting member 4 is ensured.

Of course, in some specific implementation applications, the size of the first circuit board 3 is much larger than that of the indicator 31, and the second side board 24 and the third side board 25 abut against the back surface of the first circuit board 3, and the light reflecting structure and a part of the first circuit board 3 and a part of the mounting panel 1 together enclose a relatively closed space.

Of course, in other embodiments, the first side plate 23 may abut against the back surface of the first circuit board 3. The second side panel 24 and/or the third side panel 25 may also abut the indicator light 4.

The second side plate 24 and/or the third side plate 25 are/is abutted against the first circuit board 3, so that the first circuit board 3 is pressed on the back shell 2 and the mounting panel 1 bracket to also play a role of fixing the first circuit board 3; similarly, the second side plate 24 and/or the third side plate 25 abut against the indication translucent member 4, and the indication translucent member 4 can be relatively fixed to the indication window 13.

The space is divided into a first area for arranging the indicator lamp 31 and a second area for arranging the indicator window 13; the size of the first area is larger than the size of the second area in a direction in which the second side plate 24 opposes the third side plate 25. Wherein, the first area corresponds to the first reflecting plane 201, and the second area corresponds to the second reflecting plane 202; instruct printing opacity 4 to be located the second region, the size of second region is littleer in relative direction for the light that pilot lamp 31 sent in the first region is after reflecting to the second region, because the size diminishes in relative direction in the second region, makes the second region have the effect of gathering together to light, thereby promotes the luminance of instructing printing opacity 4.

Specifically, at least one of the second side panel 24 and the third side panel 25 is a stepped structure such that a distance between the two in the second area portion is smaller than a distance between the two in the third area, for example, the second side panel 24 includes a first sub-panel 242 and a second sub-panel 241 connected and parallel to each other, in which the first sub-panel 242 is closer to the third side panel 25 than the second sub-panel 241, an area between the first sub-panel 242 and the third side panel 25 is the second area, and an area between the second sub-panel 241 and the third side panel 25 is the first area.

Alternatively, at least one of the second side plate 24 and the third side plate 25 includes an inclined plate that is away from the other side plate in a direction from the indicator light-transmitting member 4 to the indicator lamp 31; for example, the second side plate 24 includes an inclined plate and a straight plate connected to each other, wherein the inclined plate corresponds to the second region and the straight plate corresponds to the first region, and the inclined plate is inclined in a direction away from the third side plate 25 in a direction from the indicator light-transmitting member 4 to the indicator lamp 31, so that the second region becomes gradually larger in an opposite direction in the direction.

Preferably, at least the inner side of the light reflecting structure is a white mirror surface.
