[0026] When the dual-duct silent exhaust lamp body is used in an exhaust device, it is used in conjunction with an exhaust fan (not shown in the figure), wherein the exhaust fan has an exhaust duct (not shown in the figure), a wind wheel (not shown in the figure) arranged in the exhaust duct and a motor (not shown in the figure) for driving the wind wheel to rotate, the exhaust fan is stopped at the upper side of the lamp housing 1, the exhaust duct is connected with the inner ring duct 101 and / or the guide duct 103, when the motor drives the wind wheel to rotate, the gas flows from the inner ring duct 101 into the exhaust duct, and from the outer ring duct 102 first through the guide duct 103 and then through the inner ring duct 101 into the exhaust duct (or from the outer ring duct 102 into the exhaust duct through the guide duct 103).

[0027] In summary, the present embodiment provides a dual-duct silent exhaust lamp body to solve the problem that the lamp body in the existing ceiling exhaust lamp is connected to the exhaust duct through a single air intake channel, the air intake volume is small, and the wind noise is large. The problem is mainly solved by configuring an inner ring duct 101, an outer ring duct 102 and a guide duct 103 that are interconnected on the lamp housing 1. When the exhaust device draws air, the gas can flow from the inner ring duct 101 into the exhaust duct, and from the outer ring duct 102 first through the guide duct 103 and then through the inner ring duct 101 into the exhaust duct (or from the outer ring duct 102 through the guide duct 103 into the exhaust duct), thereby realizing multi-duct air intake and a large air intake volume. Therefore, when the air intake volume is equal, the wind speed is small (soft air intake) and the wind noise is low.

[0028] In the embodiment of the utility model, the outer ring air duct 102 is connected with the guide air duct 103 through the communication port 104, and the lamp housing 1 is provided with a plurality of diverter columns 105 at the communication port 104, and the plurality of diverter columns 105 extend up and down and are arranged at intervals in the circumferential direction of the lamp housing 1. The above arrangement reduces the wind speed and makes the wind noise smaller while not affecting the air intake volume by arranging a plurality of diverter columns 105 extending up and down and arranged at intervals in the circumferential direction of the lamp housing 1 at the communication port 104.

[0029] In the embodiment of the utility model, the outer ring air duct 102 has an outer air inlet 106 located at the lower side of the lamp housing 1, and the air duct wall of the outer ring air duct 102 at least facing the outer air inlet 106 is bent from bottom to top toward the connecting port 104. The above arrangement ensures the air intake volume while reducing the wind speed and wind noise by arranging the air duct wall of the outer ring air duct 102 facing the outer air inlet 106 to be bent from bottom to top toward the connecting port 104.

[0030] In the embodiment of the utility model, the inner ring air duct 101 is inclined inward from bottom to top. Since the inner ring air duct 101 is inclined inward from bottom to top, the inner ring air duct 101 is extended, and the wind speed is reduced while ensuring the air intake, reducing wind noise.

[0031] In the embodiment of the utility model, the inner ring air duct 101 has an inner ring wall 107 and an outer ring wall 108, and the inner ring wall 107 and the outer ring wall 108 are arranged at intervals in the radial direction of the lamp housing 1 to form the inner ring air duct 101, the outer ring wall 108 is on the outside, and the inner ring wall 107 is on the inside, the inner ring wall 107 is an annular plane inclined inward from bottom to top, and the outer ring wall 108 is an annular curved surface bent inward from bottom to top. The above arrangement ensures the air intake while reducing the wind speed and wind noise by configuring the inner ring wall 107 as an annular plane inclined inward from bottom to top and configuring the outer ring wall 108 as an annular curved surface bent inward from bottom to top.

[0032] In the embodiment of the utility model, the inner ring air duct 101 has an inner air inlet 109 located at the lower side of the lamp housing 1, and the setting height of the inner air inlet 109 is lower than the setting height of the outer air inlet 106. Since the inner air inlet 109 and the outer air inlet 106 are located at different heights, the inner air inlet 109 and the outer air inlet 106 do not interfere with each other, and the air intake is smooth.

[0033] In the embodiment of the utility model, the lamp housing 1 has a guide portion 110 extending from the outer air inlet 106 to the inner air inlet 109, and the guide portion 110 is arched downward. The above arrangement is configured by arranging the guide portion 110 arched downward between the outer air inlet 106 and the inner air inlet 109, and the guide portion 110 plays a guiding role to make the outer air inlet 106 and the inner air inlet 109 intake air smoothly.

[0034] In the embodiment of the utility model, the lamp housing 1 has an inner plate 111 and an outer connecting frame 112. The outer connecting frame 112 is partially arranged outside the inner plate 111 and cooperates with the inner plate 111 to form an inner ring air duct 101. The outer connecting frame 112 has an outer ring air duct 102 and a guide air duct 103. The inner plate 111 has an accommodating cavity 113 for accommodating a light source. The above arrangement makes the lamp housing 1 reasonably compact by configuring the lamp housing 1 into the inner plate 111 and the outer connecting frame 112.

[0035] In the embodiment of the utility model, the outer connecting frame 112 has a connecting portion 114, which is abutted against the upper end of the inner plate 111 and is detachably fixedly connected to the inner plate 111. Since the outer connecting frame 112 has the connecting portion 114 abutted against the upper end of the inner plate 111 and is detachably fixedly connected to the inner plate 111, the inner plate 111 and the outer connecting frame 112 can be assembled compactly and simply.
