Detailed Embodiment

[0040] The following will be combined with Figure 1-11 to describe the present utility model in detail.

[0041] A light-emitting integrated ceiling heater device includes:

[0042] The bottom case 10 includes a bottom plate 101, and side plates 102 are provided around the bottom plate 101. The space surrounded by the bottom plate 101 and the side plates 102 forms an installation cavity. The inner wall surface of the side plate 102 is a scattering arc surface 1021 protruding towards the installation cavity, and the outer wall surface of the side plate 102 is an air guiding arc surface 1022 recessed towards the installation cavity. Air can flow along the air guiding arc surface 1022, as Figure 5 shown;

[0043] The lamp cover 20, which is made of a light-transmitting material, is hermetically connected to the side plate 102 to cover the installation cavity; and

[0044] The lighting light source is installed in the installation cavity. Part of the light emitted by it directly irradiates or refracts to the side of the lamp cover 20 facing the bottom plate 101. After the other part of the light emitted by it irradiates on the scattering arc surface 1021, it irradiates to the side of the lamp cover 20 facing the bottom plate 101 at different reflection angles, as Figure 4 shown.

[0045] Therefore, by setting the scattering arc surface 1021, the user's requirements for a large lighting area and uniform lighting can be met, thereby improving the problems of concentrated light source and uneven lighting caused by the direct irradiation of the lighting light source on the lamp cover 20 in the prior art. In addition, a wind guiding arc surface 1022 recessed towards the installation cavity is provided on the outer wall surface of the side plate 102. When air enters, the air flows along the wind guiding arc surface 1022, reducing the air inlet resistance and thus increasing the air inlet volume and improving the air inlet noise.

[0046] In this embodiment, the scattering arc surface 1021 and the wind guiding arc surface 1022 are formed by stretching a conic curve. The conic curve includes an ellipse, a parabola, and a hyperbola. Among them, a circle is a special case of an ellipse, that is, a circle is an ellipse with the same major axis and minor axis. When the conic curve is an arc curve, the corresponding arc radius range value is 20 mm to 30 mm.

[0047] In this embodiment, the side plate 102 and the lamp cover 20 are adaptively clamped by a buckle 2021. Further, a plurality of buckles 2021 are provided around the lamp cover 20, as Figure 6 shown. The side plate 102 is provided with a buckle groove adapted to the buckle 2021. In other embodiments, the side plate 102 and the lamp cover 20 can also be connected to each other by fasteners.

[0048] In this embodiment, the lighting light source includes a plurality of lamp beads 301. The distance range value between the center of the lamp bead 301 close to the scattering arc surface 1021 and the bottom end of the scattering arc surface 1021 is 15 mm to 30 mm. The lighting light source further includes a lamp board 302. The lamp board 302 is provided with a plurality of lamp beads 301, and the lamp board 302 is provided with fixing holes. The bottom plate 101 is provided with fixing hooks. The lamp board 302 is detachably connected to the bottom plate 101 through the cooperation between the fixing holes and the fixing hooks. The fixing holes include mounting holes 901 and card slots 902 communicatively provided on one side of the mounting holes 901, as Figure 10As shown, the width dimension of the card slot 902 is smaller than the radial dimension of the mounting hole 901. The fixing hook includes a positioning post 1001 and an anti - detachment block 1002. One end of the positioning post 1001 is connected to the bottom plate 101, and the other end is connected with an anti - detachment block. As shown in Fig. 8, the maximum width dimension of the anti - detachment block 1002 is larger than the width dimension of the positioning post 1001, and the maximum width dimension of the anti - detachment block 1002 is smaller than the radial dimension of the mounting hole 901. During installation, the positioning post 1001 passes through the mounting hole 901, and the lamp panel 302 is moved so that the positioning post 1001 moves from the mounting hole 901 into the card slot 902, thereby preventing the lamp panel 302 from falling off.

[0049] In this embodiment, the illumination intensity of the light emitted by the lamp bead 301 in the axial direction is less than the illumination intensity of the light emitted by the lamp bead 301 in the radial direction, reducing the illumination intensity of the light directly irradiating the lamp cover 20 in the axial direction of the lamp bead 301, avoiding the appearance of point - light phenomenon at the position of the lamp cover 20 corresponding to the lamp bead 301, ensuring uniform light emission at all parts of the lamp cover 20, and achieving light - emission without dead angles. The axial light and the radial light are respectively as Figure 4 shown.

[0050] In this embodiment, the lamp cover 20 includes a positive light - emitting surface 201 and a side light - emitting surface 202 arranged around the positive light - emitting surface 201. The side light - emitting surface 202 is connected to the side plate 102, and an arc - shaped transition surface 203 is provided between the positive light - emitting surface 201 and the side light - emitting surface 202. Compared with chamfer transition, right - angle transition or other angle transitions, the arc - shaped transition surface 203 makes the light emission at the connection between the positive light - emitting surface 201 and the side light - emitting surface 202 more uniform. Among them, the radius of curvature of the arc - shaped transition surface 203 gradually increases from the side light - emitting surface 202 to the positive light - emitting surface 201. The surface of the lamp cover 20 facing the lamp bead 301 is provided with a number of diffuse - reflection particles, so that the light emitted by the lamp bead 301 is reflected or refracted by the diffuse - reflection particles and emitted from different angles, and irradiates the lamp cover 20 more evenly.

[0051] In this embodiment, it further includes a fixing strip 40. The fixing strip 40 is connected to the outside of the side plate 102, and the gap between the fixing strip 40 and the side plate 102 forms an air inlet 50, and the air inlet 50 is close to the air - guiding arc surface 1022. It further includes a fan 60. As Figure 11 shown, the air inlet end of the fan 60 is communicated with the air inlet 50, and the air outlet end of the fan 60 is provided with an air outlet assembly. The bottom plate 101 and the lamp cover 20 are provided with an installation channel 130 for installing the air outlet assembly. As Figure 3 shown, the air outlet assembly includes a seat body 701. The seat body 701 is provided with an air outlet channel 702. At the air outlet of the air outlet channel 702, there is a guiding member 703 rotatably connected to the seat body 701. One side of the guiding member 703 is connected with a driving device 80 for driving the guiding member 703 to rotate, thereby controlling the air - outlet direction and accelerating the air flow in the space.

[0052] AsFigure 2 As shown, the air guide member 703 is provided with an air guide channel, and a plurality of flow stabilizing plates 7031 arranged at intervals are provided in the air guide channel, so as to divide the air guide channel into a plurality of air ducts 7032, making the air outlet more stable. At the same time, after use, the air guide member 703 closes the air outlet of the air outlet channel 702 to prevent mosquitoes from flying into the interior of the ceiling lamp with integrated bath functions.

As Figure 6 shown, the lamp cover 20 is provided with a second through hole 1201, and a second annular convex portion 1202 extending towards the bottom plate 101 is provided at the orifice edge of the second through hole 1201.
