The lamp body is also provided with a first breathable component that connects the cavity between the light-transmitting plate and the lens and the electrical cavity, and a second breathable component that connects the electrical cavity with the outside, so that the cavity between the light-transmitting plate and the lens can maintain air pressure equilibrium with the outside. Specifically, when the light-emitting component is lit, the temperature in the cavity between the light-transmitting plate and the lens rises, causing the pressure to increase. The higher the temperature, the greater the pressure, which will affect the strength of the light-transmitting plate. In addition, when the temperature drops suddenly, the air pressure in the cavity between the light-transmitting plate and the lens is low, lower than the external air pressure. When it rains, a siphon effect is easily generated, and water will be sucked into the cavity, affecting the sealing effect.

[0041] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present application will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clearly illustrate the embodiments of the present application.

[0042] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] Example 1

[0044] This example provides a lamp, including a lamp body, a light-emitting component, a light-transmitting plate 4 and a press-fit fixing component. The light-emitting component is arranged on the lamp body, the light-emitting component includes a lens 2 for emitting light, and the light-transmitting plate 4 is covered on the lens 2 by the press-fit fixing component.

[0045] The press-fit assembly has a press-fit portion at one end and a fixing portion at the other. A fixing portion is provided on the lamp body, and the fixing portion and the fixing portion form an interference fit to secure the press-fit assembly to the lamp body. The press-fit portion abuts the side of the light-transmitting plate 4 facing away from the lens 2. The interference fit between the fixing portion and the fixing portion compresses and secures the light-transmitting plate 4 against the lens 2.

[0046] The press-fit fixing assembly is fixed to the lamp body through interference fit between the fixing part and the fixed matching part. At the same time, the press-fit fixing assembly presses and fixes the light-transmitting plate 4 on the lens 2 through the press-fit part. The interference fit connection makes installation simple and convenient.

[0047] Furthermore, the press-fit fixing assembly is provided with a plurality of engaging portions, and the lamp body is provided with a plurality of engaging portions corresponding to the engaging portions. The engaging portions engage with the engaging portions to secure the press-fit fixing assembly to the lamp body. In this embodiment, the engaging portions are provided on the fixing portion, and the engaging portions are provided on the fixing engaging portion. When the fixing portion and the fixing engaging portion have an interference fit, the engaging portions engage with the engaging portions.

[0048] The press-fit fixing assembly is connected by interference fit between the fixing portion and the fixing matching portion, and then connected by snap fit between the snap fit portion and the snap fit portion, which further improves the connection strength and safety of the press-fit fixing assembly and prevents the press-fit fixing assembly from falling off the lamp body.

[0049] Example 2

[0050] 1 to 11 , based on the basic concept of Example 1, this example provides a specific application example of a lamp, wherein the lamp body is specifically a lamp housing, an electrical cavity 13 is provided in the lamp housing, a power supply is provided in the electrical cavity 13, and a light-emitting component is provided at the opening of the electrical cavity 13. The light-emitting component includes a lens 2 and a PCB board, and the lens 2 is provided on the PCB board.

[0051] The light-transmitting plate 4 is covered on the lens 2 by a press-fit fixing component, which is specifically a press frame 3. The fixing part is a circle of fixing flanges 5 protruding from the press frame 3 toward the lamp body, and the fixing matching part is a circle of fixing grooves 6 corresponding to the position of the fixing flanges 5. The fixing flanges 5 are arranged in the fixing grooves 6 and are interference fit with the fixing grooves 6.

[0052] The pressing part is a circle of pressing flange 7 protruding inward on the pressing frame 3. The pressing flange 7 presses the peripheral edge of the light-transmitting plate 4 through the interference fit force between the fixing flange 5 and the fixing groove 6, so that the light-transmitting plate 4 is tightly attached to the lens 2. When the light-transmitting plate 4 is impacted, the impact energy is transmitted to the lens 2 through the light-transmitting plate 4, and the lens 2 absorbs part of the energy. At the same time, the lens 2 supports the light-transmitting plate 4, reducing the deformation of the light-transmitting plate 4. In this embodiment, the light-transmitting plate 4 is made of glass, which is hard to deform and fragile, and the lens 2 is made of plastic, which has a certain elasticity and a buffering effect. When the light-transmitting plate 4 is impacted, this design reduces the cracks in the light-transmitting plate 4. At the same time, the pressing frame 3 in this embodiment is also made of plastic, which has a certain elasticity and a buffering and impact-resistant effect, which can further protect the light-transmitting plate 4.

[0053] The engaging portion is specifically a buckle 8. An accommodating notch 10 is provided on the fixing flange 5. The buckle 8 is disposed within the accommodating notch 10, and the end of the buckle 8 away from the lens 2 is connected to the inner wall of the end of the accommodating notch 10 away from the lens 2. The engaging portion is specifically a slot 9, which is provided on one inner wall of the fixing groove 6. In this embodiment, the slot 9 is provided on the outer inner wall of the fixing groove 6 and extends through the outer inner wall of the fixing groove 6.

[0054] The buckle 8 is buckled into the slot 9 through elastic deformation. The fixing slot 6 is provided with an avoidance groove 11 on the inner wall on the other side opposite to the slot 9. The avoidance groove 11 is used to avoid the buckle 8 when the buckle 8 is elastically deformed, so that the buckle 8 can be fully deformed to smoothly cooperate with the slot 9.

[0055] The lamp housing is provided with a sealing groove 12 surrounding the light-emitting assembly, with a sealing ring positioned within it. The light-transmitting plate 4 covers the sealing groove 12 and compresses the sealing ring. The lamp housing is provided with a first vent component that connects the cavity between the light-transmitting plate 4 and lens 2 with the electrical cavity 13, and a second vent component that connects the electrical cavity 13 with the outside. In this embodiment, the first vent component is a breathing hole 14, which is positioned within the sealing groove 12. It should be noted that although the light-transmitting plate 4 and lens 2 are designed to fit snugly in this embodiment, the cavity between them and the sealing groove 12 remains connected. The second vent component is specifically a vent valve 15, located on the wall of the electrical cavity 13.

[0056] A sealing groove 12 and a sealing ring are provided to achieve a waterproof seal for the light-emitting assembly. Furthermore, a breathing hole 14 is provided on the lamp housing, connecting the cavity between the light-transmitting plate 4 and the lens 2 with the electrical cavity 13, as well as a vent valve 15 connecting the electrical cavity 13 with the outside. These allow the cavity between the light-transmitting plate 4 and the lens 2 to maintain pressure equilibrium with the outside. Specifically, when the light-emitting assembly is illuminated, the temperature within the cavity between the light-transmitting plate 4 and the lens 2 rises, causing an increase in pressure. The higher the temperature, the greater the pressure, which affects the strength of the light-transmitting plate 4. Furthermore, when the temperature suddenly drops, the pressure within the cavity between the light-transmitting plate 4 and the lens 2 drops below the outside pressure. This can easily create a siphon effect when it rains, drawing water into the cavity and affecting the sealing effect. However, the provision of the breathing hole 14 and vent valve 15 ensures that the internal pressure of the lamp remains balanced with the external atmospheric pressure regardless of the lamp's state, thus preventing the influence of the internal pressure.

[0057] The pressing frame 3 of the present application is fixed to the lamp housing through the interference fit between the fixing flange 5 and the fixing groove 6. At the same time, the pressing frame 3 presses the light-transmitting plate 4 to the lens 2 through the pressing flange 7. The interference fit connection makes installation simple and convenient. At the same time, a plurality of buckles 8 are provided on the pressing frame 3, and a plurality of slots 9 corresponding to the buckles 8 are provided on the lamp housing. The buckles 8 are provided on the fixing flange 5, and the slots 9 are provided on the fixing slot 6. When the fixing flange 5 and the fixing slot 6 have an interference fit, the buckles 8 and the slots 9 engage with each other. This allows the pressing frame 3 to be connected to the lamp housing through the interference fit of the fixing flange 5 and the fixing slot 6, and then to be connected to the lamp housing through the buckles 8 and the slots 9. This further improves the connection strength and safety of the pressing frame 3 and prevents the pressing frame 3 from falling off the lamp housing.

[0058] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above embodiments. Even if various changes are made to the present application, if these changes fall within the scope of the claims of the present application and their equivalents, they will still fall within the scope of protection of the present application.
