[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1

[0023] Please refer to Figure 1 -5.

[0024] The present embodiment provides a waterproof ceiling lamp, a waterproof ceiling lamp, comprising a main housing 1 in which a lamp body is installed, wherein the main housing 1 is provided with an inner cavity 2, and the inner cavity 2 is used to install the lamp body, such as a lamp tube or an LED lamp, a lamp controller, etc. The main housing 1 is connected to a cover 20, and the cover 20 is connected to an outer ring 21, forming a complete set of waterproof ceiling lamps.

[0025] In the embodiments of the present utility model application, please refer to Figure 3 and Figure 5 The upper end surface of the inner cavity 2 is provided with a sealing step 3, the upper end surface of the sealing step 3 is provided with a sealing ring 4, a rear cover 5 is provided on the upper side of the sealing ring 4, and the two sides of the sealing step 3 are provided with a concave lower water tank 6, the lower water tank 6 leads to the drainage hole 7 provided on the circumference of the main shell 1. When there is water accumulation on the rear cover 5, the accumulated water flows into the lower water tank 6 and then flows out from the drainage hole 7. The side of the inner cavity 2 is provided with a first through hole 9 for installing a waterproof connector 8, and the waterproof connector 8 is used to pass the wire. The side of the inner cavity 2 is provided with a second through hole 11 for installing a breathing screw 10, and the breathing screw 10 is used to block water vapor.

[0026] Furthermore, the main housing 1 is provided with a lock cavity 13 for installing a lock 12. The lock 12 is fixed to the lock cavity 13 by screws, and the ceiling lamp can be installed at a to-be-determined position by the locks 12 on both sides.

[0027] In the embodiments of the present utility model application, please refer to Figure 4 The breathing screw 10 includes a bolt portion 14 for installation and fixing. The bolt portion 14 is hollow, and a waterproof breathable membrane 15 is arranged inside it, and a bolt cover 16 is fixed at its end. The breathing screw 10 is arranged to allow air to pass through and prevent water vapor from entering the inner cavity 2. When the lamp is lit, the whole lamp will heat up, and the internal gas will overflow to the outside. When the lamp is turned off, the heat of the whole lamp will drop. Due to the principle of thermal expansion and contraction, the external gas will tend to enter the inner cavity 2, and the waterproof breathable membrane 15 in the breathing screw 10 can isolate water vapor from entering, while maintaining the balance of the pressure difference between the inside and outside of the lamp. The breathing screw is a prior art, also known as a waterproof breathable valve.

[0028] Furthermore, the main housing 1 is provided with a wire clamp 17 for fixing the lamp wires. There are two groups of wire clamps 17, and the center lines of the two groups of wire clamps 17 are staggered from each other. The center lines of the two groups of wire clamps 17 are not in a straight line. When the lamp wires are pulled, the pulling force can be decomposed and reduced, thereby preventing the wires from being pulled out or causing poor line contact.

[0029] Furthermore, the main housing 1 is provided with a bayonet 18, and the rear cover 5 is provided with a bayonet slot 19. When the rear cover 5 is installed, the bayonet slot 19 is engaged with the bayonet 18. This structure can conveniently limit one end of the rear cover 5, and the other end of the rear cover 5 is fixed with bolts, that is, the rear cover 5 can be completely fixed.

[0030] The beneficial effect of the utility model is that by setting the lower water tank 6 and the drainage hole 7 on the main shell 1, water can flow out from the drainage hole 7 and will not enter the inner cavity 2. By setting the breathing screw 10, its function is to allow air to pass through and prevent water vapor from entering the inner cavity 2. When the lamp is lit, the whole lamp will heat up and the internal gas will overflow to the outside. When the lamp is turned off, the heat of the whole lamp will drop. Due to the principle of thermal expansion and contraction, the external gas will tend to enter the inner cavity 2, and the waterproof and breathable membrane 15 in the breathing screw 10 can isolate water vapor from entering, while maintaining the balance of the pressure difference between the inside and outside of the lamp. This new structure is simple and compact, and has a good waterproof effect.
