The tri-proof light is a kind of lamps and lanterns that are applied to places such as rain, dust are more, corrosivity is stronger, and it mainly includes the lamp body and sets up the light-emitting component in the lamp body, and wherein the lamp body includes lamp shade and base, adopts special anti-oxidation, anticorrosive material usually, and the connection accessible of lamp shade and base is glued or is installed the sealing member mode and realize. However, the gluing has poor waterproof effect, so that a higher waterproof grade is difficult to achieve, and the use scene of the lamp is limited; among the current tri-proof light structure, the installation of sealing member often requires higher precision, has the loaded down with trivial details scheduling problem of installation, and leads to sealed effect not good because of size deviation easily, is difficult to reach waterproof grade IP 65.

To the above technical problem, an embodiment of the present invention provides a lamp having a length direction and a width direction, including a base 10 and a lamp cover 20, wherein the base 10 is used for fixing a light emitting component 30, and the base 10 and the lamp cover 20 cooperate to form a cavity for accommodating the light emitting component 30. The base 10 is provided with a first clamping groove 11 and a second clamping groove 12 along the length direction of the lamp, and a sealing piece 13 is arranged in the second clamping groove 12; the lamp shade 20 is provided with a first clamping part 21 which is matched with the first clamping groove 11 along the length direction of the lamp so as to prevent the first clamping part and the first clamping groove from being separated, and a second clamping part 22 which extends into the second clamping groove 12 to extrude the sealing piece 13 so as to enable the sealing piece to be expanded in the second clamping groove 12; referring to fig. 1-2, the coordinate system (X, Y, Z) in fig. 2 indicates the direction, wherein X is the length direction, Y is the width direction, and Z is the height direction. During assembly, when the first clamping portion 21 and the second clamping groove 12 are fastened in place, the second clamping groove 12 just can stretch into the second clamping groove 12 and extrude the sealing element 13, so that the expanded sealing element 13 is in interference fit with the second clamping groove 12.

The lampshade 20 is made of transparent, anticorrosive and anti-oxidation materials to ensure higher light transmittance and longer service life; the base 10 is generally made of metal to provide a certain mechanical strength for supporting the components; the sealing member 13 can prevent or inhibit the intrusion of external fluid or solid particles into the interior of the lamp from between the adjacent joint surfaces, and includes, according to the material classification: silica gel, nitrile rubber, fluorosilicone rubber, rubber and the like.

For example, in one embodiment, the second clamping portion 22 and the lamp housing 20 are integrally formed, and both are made of PC material; the PC material is a tough thermoplastic resin, is colorless and transparent, has good optical performance, and also has the characteristics of good mechanical performance, flame retardant performance, heat resistance, impact resistance and the like; the die can be integrally cast, so that the connection strength of the die and the die is ensured, and the die are not easy to separate. In addition, the base 10 of the lamp is made of aluminum profiles with good heat dissipation performance and sufficient mechanical strength; the sealing element 13 is a silica gel strip, which has stable chemical property and good thermal stability, and can generate certain elastic deformation when being extruded by the second clamping part 22, so as to be in interference fit with the contact surface of the second clamping groove 12; sealing member 13 length is the same with second draw-in groove 12 length, and during the assembly, requires that the terminal surface of both flushes, avoids producing the installation to other subassemblies on the one hand and interferes, and on the other hand is favorable to promoting sealed effect.

The interference fit is used for achieving the purpose of tight connection by means of interference after the two accessories are assembled, and the sealing piece 13 is in interference fit with the second clamping groove 12 to seal a channel for fluid entering the lamp. Specifically, in an embodiment, the second card slot 12 is surrounded by a first sidewall 121, a second sidewall 122, and a bottom wall 123 located between the first sidewall 121 and the second sidewall 122, the first sidewall 121 is located at an outer side relative to the second sidewall 122, and the sealing member 13 is in interference fit with the first sidewall 121 and/or the second sidewall 122; see FIGS. 3-4. The sealing member 13 is in interference fit with at least one side wall to ensure sealing effect, and in order to achieve the waterproof grade IP65 and above, the interference between the sealing member 13 and the first side wall 121 and/or the second side wall 122 is required to be about 0.1 mm.

Further, in an embodiment, the sealing member 13 is in interference fit with the first side wall 121, so that a water flow channel is blocked from the outermost side of the lamp, and the safety is higher; and a positioning structure 132 for preventing the second side wall 122 from being separated is arranged between the second side wall and the second side wall, so that the assembling firmness is improved. The positioning structure 132 may be disposed on the sealing member 13 or disposed on the second sidewall 122, for example, the sealing member 13 is an irregular convex structure disposed toward a side of the second sidewall 122.

In order to facilitate the insertion and positioning of the second clamping portion 22, in an embodiment, the sealing member 13 is provided with a guide groove 131 into which the second clamping portion 22 extends, see fig. 2. The second clamping portion 22 enters from one end of the length direction along the guide groove 131 and moves in the guide groove 131 until the lampshade 20 completely covers the base 10, and the second clamping portion 22 evenly extrudes the sealing member 13 in a moving process, so that the sealing member 13 expands tightly to realize interference fit between the sealing member 13 and the first side wall 121.

The structure of the second clamping portion 22 influences whether it can extend into the guide slot 131 and press the sealing member 13, in an embodiment, the second clamping portion 22 is an elastic structure protruding from the inner wall of the lamp cover 20 toward the base 10 and is bent; see fig. 2, 4. The direction of the bending determines whether the sealing member 13 is in interference fit with the first sidewall 121 or the second sidewall 122, and the magnitude of the bending affects the magnitude of the pressing interference of the sealing member 13 with the first sidewall 121 or the second sidewall 122.
