The light of the indicating light source 32 is transmitted outward through the light guide channel 2, the light guide channel 2 can separate the light of the illumination light source 31 and the light of the indicating light source 32, so that they do not affect each other, which is convenient for users to check the working state of the lamp from the outside of the lamp and meets the national standard; the light guide channel 2 is in the shape of a through circular tube, so that the light guide channel 2 has the function of light collection, the light of the indicating light source 32 cannot spread outward and is gathered in the light guide channel 2 to be displayed outward, and the light transmission of the indicating light source 32 is clear.

[0043] The light guide channel 2 and the housing 1 are integrally injection molded by plastic, which can greatly speed up the molding time of the product and save the cost of the product.

[0044] Embodiment one

[0045] As shown in the drawings, Figure 1 , Figure 2 , Figure 3 The light guide channel 2 is arranged outside the side wall 11 of the housing 1; the light source plate 3 is provided with a first protruding part 33 protruding outward, the indicating light source 32 is arranged on the first protruding part 33; the light transmission part 4 is provided with a second protruding part 41 protruding outward, the second protruding part 41 covers the light guide channel 2, and the second protruding part 41 covers the light outlet 22.

[0046] The shell 1 is provided with a back plate 13, the light guide channel 2 is provided with an inlet plate part 23 connected with the back plate 13, the first protruding part 33 enters the light guide channel 2 through the inlet plate part 23; the height of the inlet plate part 23 is greater than the sum of the height of the indicating light source 32 and the height of the light source plate 3; when assembling, the light source plate 3 needs to be inclined to extend to the bottom of the light guide channel 2 and then be laid flat by pressing the light source plate 3, so that the first protruding part 33 can more conveniently enter the light guide channel and the product assembling speed is accelerated.

[0047] The light-transmitting part 4 is provided with an assembling edge 42 extending towards the inside of the shell 1, the assembling edge 42 and the side wall 11 are provided with mutually matched buckle mechanisms 5, the light-transmitting part 4 is fixed on the shell 1 through the buckle mechanisms 5, the light guide channel 2 is provided with a notch 24 near the opening part 12, the assembling edge 42 covers the notch 24, and it is noted that the functional part of the assembling edge 43 covering the notch 24 is in communication with the light guide channel 2, and at this time, the assembling edge 43 covering the notch 24 position should be regarded as a part of the light guide channel 2.

[0048] The light guide channel 2 is in the shape of a circular truncated cone with the upper part being narrow and the lower part being wide, and the size of the light outlet 22 is greater than the size of the light inlet 21, so that the light of the indicating light source 32 can be better gathered to the light outlet 22, and the light of the external indicating light source 32 can be more clearly presented externally; the light guide channel 2 further comprises a placing plate part 25, the placing plate part 25 is in communication with the light inlet 21, the size of the placing plate part 25 is greater than the size of the light inlet 21, the first protruding part 33 is arranged in the placing plate part 25, and the placing plate part 25 increases the space of the light guide channel 2, so as to facilitate the first protruding part 33 to enter the light guide channel 2.

[0049] In some lamps, in order to facilitate production and better light efficiency, the side wall 11 of the shell 1 is inclined, that is, the size of the back plate 13 is smaller than the size of the opening part 12, but the light guide channel 2 cannot be directly parallel to the side wall 11 using this structure, and therefore, in order to facilitate production, the side of the light guide channel 2 is recessed with the side wall 11 of the shell 1.

[0050] Embodiment two

[0051] As Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the light guide channel 2 is arranged in the side wall 11 of the shell 1, the shell 1 is provided with an assembling opening 14 at the back, the illumination light source 31 is arranged inside the shell 1, the light source plate 3 covers the assembling opening 14, the light guide channel 2 is in contact with the light transmission piece 4, the light of the indicating light source 32 is irradiated on the light transmission piece 4 through the light guide channel 2, the indicating light source 32 is arranged in the light guide channel 2, and the light guide channel 2 is in contact with the light source plate 3. The structure can accelerate the assembly speed of the product, avoid the light of the indicating light source 32 from being transmitted to the irradiation range of the illumination light source 31, and make the light of the indicating light source 32 better converge in the light guide channel 2 and be presented outward through the light transmission piece 4.

[0052] In some embodiments, because light diffusion needs distance, the light guide channel 2 does not need to be in contact with the light transmission piece 4, and even if there is a gap between the light outlet 22 and the light transmission piece 4, the light of the indicating light source 32 can be transmitted to the light transmission piece 4. Because the indicating light source 32 protrudes from the light source plate 3, the light inlet 21 does not need to be in contact with the light source plate 3, and even if there is a gap between the light inlet 21 and the light source plate 3, the light of the indicating light source 32 can be transmitted into the light guide channel 2; but in order to avoid the light of the indicating light source 32 from escaping from the light guide channel 2, the size of the gap cannot be too large, and the length of the light guide channel 2 should be greater than or equal to three quarters of the height of the side wall 11.

[0053] In some embodiments, the light source plate 3 is arranged inside the shell through the assembling opening 14, or the assembling opening 14 is provided with a cover body, and the light source plate 3 is assembled on the cover body, which can also achieve the purpose of assembling the light source plate 3 on the shell 1.

[0054] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, and the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and these changes and modifications all fall within the protection scope of the present application.
