Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of a waterproof straight tube lamp 50 according to an embodiment of the present invention, and fig. 2 is an exploded schematic view of the waterproof straight tube lamp 50 according to an embodiment of the present invention. As shown in fig. 1 and fig. 2, the present invention provides a waterproof straight tube lamp 50 in an embodiment, in this embodiment, the waterproof straight tube lamp 50 is an LED straight tube lamp, that is, the internal light source of the straight tube lamp 50 is LED, but not limited thereto. In various embodiments, the straight tube lamp 50 may be a straight tube lamp using any one of the light emitting sources. In the present embodiment, the straight tube lamp 50 includes a lamp tube 100, a lamp cap 300, a waterproof lamp cover 1300 and a connecting member 1400. The LED lamp panel (not shown) is disposed in the lamp tube 100, the lamp cap 300 is coupled to one end of the lamp tube 100 in the axial direction (the common direction of the central axes of the lamp tube 100), and the end of the lamp cap 300 away from the lamp tube 100 is provided with a conductive terminal 310. The connection member 1400 connects the lamp cap 300 and an external power source (not shown), and the waterproof lamp sleeve 1300 covers at least a portion of the connection member 1400, the lamp cap 300 and the lamp 100. The lamp 100 may be a plastic lamp, a glass lamp, a plastic and metal mixed lamp, or a glass and metal mixed lamp.

Referring to fig. 3 again, fig. 3 is a sectional view of a waterproof straight lamp 50 according to an embodiment of the present invention. As shown in fig. 1 to 3, the connection member 1400 includes a plug 1410 and a wire 1420 electrically connected to the plug 1410, wherein the plug 1410 is provided with a socket corresponding to the conductive terminal 310. When the plug 1410 is electrically connected to the conductive terminal 310 of the lamp cap 300, the conductive terminal 310 is correspondingly inserted into the insertion hole of the plug 1410, so that the connection member 1400 is electrically connected to the lamp cap 300. The plug 1410 is adapted to be integrally formed with the inner peripheral surface of the conductive terminal 310 as a sealing ring having an inner diameter smaller than the outer diameter of the conductive terminal 310, such that the wire 1420 is in airtight engagement with the conductive terminal 310 and prevents the ingress of moisture. The waterproof lamp cover 1300 is sleeved outside the connection member 1400. The waterproof lamp holder 1300 includes a cap sleeve 1310, a plug sleeve 1320, and a wire sleeve 1330, which are coaxially disposed, and the plug sleeve 1320 is integrally connected between the wire sleeve 1330 and the cap sleeve 1310.

The wire 1420 can pass through the opening of the wire sleeve 1330, and the wire sleeve 1330 is hermetically sleeved outside the wire 1420. The lamp cap sleeve 1310 and the plug sleeve 1320 are hermetically sleeved outside the lamp cap 300 and cover the seam 303 between the lamp cap 300 and the lamp tube 100, and the plug 1410 is accommodated in the plug sleeve 1320. In other embodiments, the base sleeve 1310 covers only a portion of the base (not shown), that is, the base sleeve 1310 does not cover the seam 303 between the base 300 and the lamp tube 100, so that the length of the base sleeve 1310 is reduced to reduce the material usage and reduce the cost.

For example, lamp cap sleeve 1310 is sleeved outside lamp cap 300 and lamp tube 100, and plug sleeve 1320 is sleeved outside plug 1410. Since lamp cap sleeve 1310 is configured to match the outer contours and dimensions of lamp cap 300 and lamp tube 100, plug sleeve 1320 is configured to match the outer contours and dimensions of plug 1410, and wire sleeve 1330 is configured to match the outer contours and dimensions of wire 1420, and the radial dimension of wire 1420 is smaller than the radial dimension of plug 1410, and the radial dimension of plug 1410 is smaller than the radial dimensions of lamp tube 100 and lamp cap 300, the diameter of wire sleeve 1330 is smaller than the diameter of lamp cap sleeve 1310 and plug sleeve 1320, and the diameter of plug sleeve 1320 is smaller than the diameter of lamp cap sleeve 1310. Additionally, the caliber of plug ferrule 1320 is at a maximum at the end adjacent to lamp cap ferrule 1310 and at a minimum at the end adjacent to wire ferrule 1330. In some embodiments, the aperture of plug ferrule 1320 tapers from an end adjacent to lamp cap ferrule 1310 to an end adjacent to wire ferrule 1330. In some embodiments, the bore of plug ferrule 1320 may also be axially uniform.

In the present embodiment, the wire sleeve 1330 has elasticity, and the caliber of the wire sleeve 1330 is smaller or slightly smaller than the diameter of the wire 1420, so when the wire 1420 penetrates into the wire sleeve 1330, the wire sleeve 1330 is radially expanded by the wire 1420, and the expanded wire sleeve 1330 generates an elastic restoring force due to the inherent elasticity, and the elastic restoring force of the wire sleeve 1330 applies a pressure to the wire 1420, which means that the wire sleeve 1330 and the wire 1420 are in a tight fit state. Due to the tight fit, the wire sleeve 1330 and the wire 1420 are tightly attached to each other to form an airtight seal. In other embodiments, the wire sleeve 1330 has a larger diameter than the wire 1420, so that it is easier to thread the wire 1420 into the wire sleeve 1330, facilitating assembly, and after assembly, the wire sleeve 1330 is tightened by a clamp or other clampable member to form a seal.

Similarly, in the embodiment, the base sleeve 1310 has elasticity, and the aperture of the base sleeve 1310 is smaller than or slightly smaller than the diameters of the base 300 and the lamp 100, so when the base sleeve 1310 is sleeved on the outer circumferential surfaces of the base 300 and the lamp 100 and covers the seam 303, the base sleeve 1310 is radially expanded by the base 300 and the lamp 100, and the expanded base sleeve 1310 generates an elastic restoring force due to the inherent elasticity, and the elastic restoring force of the base sleeve 1310 applies a pressure to the base 300, the lamp 100 and the seam 303, which means that the base sleeve 1310, the base 300 and the lamp 100 are in a tight fit state. Due to the tight fit, the cap sleeve 1310, the cap 300 and the lamp tube 100 are tightly adhered to each other and tightly cover the seam 303, so as to form an airtight seal. In other embodiments, the diameter of the socket sleeve 1310 is larger than the diameter of the socket 300 and the lamp 100, so that the socket sleeve 1310 can be easily sleeved into the socket 300 and the lamp 100, the assembly is convenient, and after the assembly is completed, the socket sleeve 1310 is tightened by a clamping component of the clamp lamp to form a seal.

In the present embodiment, the waterproof lamp sleeve 1300 is a silicone sleeve, and the lamp cap sleeve 1310, the plug sleeve 1320 and the wire sleeve 1330 have elasticity. In various embodiments, the waterproof lamp sleeve 1300 may be made of other suitable materials. Waterproof lamp sleeve 1300 may be integrally formed.

In the present embodiment, the straight tube lamp 50 is a single-end power supply, in other words, the positive and negative poles of the lamp 100 are both disposed on the base 300 at one end of the lamp 100 in the axial direction, for example, two conductive terminals 310 are provided, one of which is a positive pole, and the other is a negative pole. As shown in fig. 1 to 3, since the straight tube lamp 50 is single-ended, the straight tube lamp 50 further includes a lamp cap 300a, the lamp cap 300a is disposed at another end of the lamp tube 100 in the axial direction, and the difference between the lamp cap 300 and the lamp cap 300a is that the lamp cap 300a is not responsible for connecting an external power source, and therefore the lamp cap 300a does not have any conductive terminal 310 and does not need to connect any connecting member 1400. Since the light head 300a does not have the conductive terminal 310 and the connection member 1400 is not required, the straight tube lamp 50 may let liquid or vapor enter at the joint 303 between the lamp tube 100 and the light head 300a at the end near the light head 300 a.

According to the above description of the single-ended power-in, in the present embodiment, the straight tube lamp 50 further includes the waterproof lamp socket 1300a, and the waterproof lamp socket 1300a is different from the waterproof lamp socket 1300a in that the waterproof lamp socket 1300a does not have the plug bushing 1320 and the wire bushing 1330, and conversely, the waterproof lamp socket 1300a includes the base bushing 1310 and the closed end 1340, and the closed end 1340 is connected to and closes the end of the base bushing 1310 that is axially away from the base 300 a. Referring to the aforementioned airtight effect of the cap sleeve 1310 of the waterproof cap 1300, when the cap sleeve 1310 of the waterproof cap 1300a is sleeved on the outer circumferential surfaces of the lamp 100 and the cap 300a and covers the seam 303 between the lamp 100 and the cap 300a, the cap sleeve 1310 of the waterproof cap 1300a is also tightly attached to the outer circumferential surfaces of the lamp 100 and the cap 300a and tightly covers the seam 303, thereby forming airtight.

In various embodiments, the straight tube lamp 50 may be powered on at both ends, in other words, both ends of the lamp tube 100 of the straight tube lamp 50 in the axial direction need to be connected with an external power source. In this case, the straight lamp 50 may include two identical lamp caps 300 and two connecting members 1400, the two lamp caps 300 are respectively located at two ends of the lamp tube 100 in the axial direction, and the two lamp caps 300 are respectively connected to the two connecting members 1400 through the conductive terminals 310 thereof. Moreover, the straight tube lamp 50 may further include two identical waterproof lamp caps 1300, and the two waterproof lamp caps 1300 are respectively sleeved on the two lamp caps 300 and the two connecting members 1400. As shown in fig. 1 to 3, when the straight tube lamp 50 is powered on at both ends, the waterproof lamp sleeve 1300a and the lamp cap 300a located below the drawing plane may be replaced with another waterproof lamp sleeve 1300 and lamp cap 300 symmetrical to the upper side of the drawing plane.

As shown in fig. 1 to 3, in the present embodiment, two first annular protrusions 1311 are further integrally formed on the outer circumferential surface of the base sleeve 1310, the two first annular protrusions 1311 are arranged at intervals in the axial direction of the straight tube lamp 50, and a first receiving groove 1313 is formed between the two first annular protrusions 1311. In the case where the straight tube lamp 50 needs to be hung, for example, in a marine animal and plant farm, since it is difficult to horizontally install the straight tube lamp 50 above the pool of the farm, in practical applications, the straight tube lamp 50 is mostly hung vertically above the pool (i.e. the axial direction of the straight tube lamp 50 is perpendicular to the ground/horizontal plane) to simplify the installation and meet the lighting requirement. Although the hanging rope can be tied to the straight lamp 50 first and then hung on the rack vertically, due to the gravity, the straight lamp 50 may slide in the axial direction of the hanging rope, so that the straight lamp 50 may slip off the hanging rope and fall off in the vertical hanging state. Since the two first annular protrusions 1311 of the present embodiment are arranged at intervals in the axial direction of the straight tube lamp 50 and form the first receiving grooves 1313, in the above-mentioned vertical hanging state, the hanging rope can be tied up in the first receiving grooves 1313 and then hung on the rack, and the first annular protrusions 1311 can block the sliding of the hanging rope in the axial direction of the straight tube lamp 50, so as to effectively avoid the situation that the straight tube lamp 50 slips off the hanging rope and falls off.

As shown in fig. 1 to 3, in the present embodiment, two second annular protrusions 1312 are integrally formed on the outer peripheral surface of the base sleeve 1310, the two second annular protrusions 1312 are spaced from each other in the axial direction of the straight tube lamp 50, and a second receiving groove 1314 is formed between the two second annular protrusions 1312. The first annular protrusion 1311 and the second annular protrusion 1312 are respectively located at both ends of the base sleeve 1310 in the axial direction, and the first annular protrusion 1311 is adjacent to the plug sleeve 1320. In the above-mentioned state of vertical hanging, the hanging rope or hanging strip can also be tied up in the second receiving groove 1314, and then hung on the rack, and the second annular protrusion 1311 can also block the sliding of the hanging rope or hanging strip in the axial direction of the straight tube lamp 50, so as to effectively avoid the situation that the straight tube lamp 50 falls off the hanging rope or hanging strip.

As shown in fig. 1 to 3, in the present embodiment, the lamp head sleeve 1310 of the waterproof lamp sleeve 1300a includes two first annular protrusions 1311 and two second annular protrusions 1312, a first receiving groove 1313 is formed between the two first annular protrusions 1311, and a second receiving groove 1314 is formed between the two second annular protrusions 1312. The structure, arrangement and function of the lamp head sleeve 1310 of the waterproof lamp sleeve 1300a and the first annular protrusion 1311, the second annular protrusion 1312, the first receiving groove 1313 and the second receiving groove 1314 thereon may refer to the first annular protrusion 1311, the second annular protrusion 1312, the first receiving groove 1313 and the second receiving groove 1314 of the lamp head sleeve 1310 of the waterproof lamp sleeve 1300, which will not be described herein again. In some applications, the hanging rope or strap can be tied to the first receiving groove 1313 or the second receiving groove 1314 of the waterproof lamp cover 1300a and hang the straight tube lamp 50 vertically. In some applications, the hanging rope or the hanging strip can be respectively tied to the first receiving groove 1313 or the second receiving groove 1314 of the waterproof lamp cover 1300 and the first receiving groove 1313 or the second receiving groove 1314 of the waterproof lamp cover 1300a, so that the straight lamp 50 can be horizontally hung or the straight lamp 50 can be hung at an inclined angle.

As shown in fig. 1 to 3, in the present embodiment, a radial rim 1315 is provided between the plug bushing 1320 and the base bushing 1310, and the radial rim 1315 is formed by a step structure between the plug bushing 1320 and the base bushing 1310. When the waterproof lamp sleeve 1300 is properly sleeved on the lamp tube 100, the lamp cap 300 and the connecting member 1400, the end of the lamp cap 300 will abut against the radial rim 1315 in the axial direction, and the tight abutting between the radial rim 1315 and the lamp cap 300 also helps to achieve the air-tight and waterproof effects.

Referring to fig. 4 and 5, fig. 4 and 5 are partial sectional views of a straight tube lamp 50 capable of preventing water according to an embodiment of the present invention, wherein the waterproof lamp cover 1300 in fig. 4 is not yet hermetically sleeved on the connecting member 1400, the lamp cap 300 and the lamp tube 100, or the waterproof lamp cover 1300 in fig. 5 is removed from the lamp cap 300 and the lamp tube 100, and the waterproof lamp cover 1300 in fig. 5 is hermetically sleeved on the connecting member 1400, the lamp cap 300 and the lamp tube 100. As shown in fig. 4 and 5, in the present embodiment, the waterproof lamp cover 1300 is selectively axially movable relative to the connection member 1400, and the wire sleeve 1330 is relatively moved along the wire 1420 when the waterproof lamp cover 1300 and the connection member 1400 are relatively moved. As shown in fig. 5 to 4, the waterproof lamp sleeve 1300 is axially moved relative to the connecting member 1400 to be away from the lamp cap 300, so that the lamp cap sleeve 1310 is separated from the lamp cap 300 and the lamp tube 100 and the plug 1410 is exposed out of the waterproof lamp sleeve 1300. As shown in the sequence of fig. 4 to 5, the waterproof lamp sleeve 1300 is axially moved relative to the connecting member 1400 to sleeve the lamp cap 300 and the lamp tube 100, so that the lamp cap sleeve 1310 completely covers the lamp cap 300 and a portion of the lamp tube 100 adjacent to the lamp cap 300, and the plug sleeve 1320 completely covers the plug 1410.

As shown in fig. 4 and 5, in this embodiment, at least one sealing ring 1316 is further integrally formed on the inner circumferential surface of the base sleeve 1310, and the sealing ring 1316 can be pressed against the outer circumferential surface of the lamp tube 100, preferably, the sealing ring 1316 is located beyond the seam 303 in the axial direction of the lamp tube 100. Compared to the embodiment in which the inner circumferential surface of the base sleeve 1310 is smooth, in the present embodiment, since the sealing ring 1316 is convex relative to the inner circumferential surface of the base sleeve 1310, the sealing ring 1316 can generate a greater pressure on the pressed surface (i.e., the outer circumferential surface of the lamp tube 100), and thus the sealing ring 1316 can provide a better airtight or waterproof effect. In some embodiments, the number of sealing rings 1316 is more than two, and the plurality of sealing rings 1316 are closely arranged to each other in the axial direction to increase the air-tight or water-tight effect. Further, the sealing rings 1316 form a cavity therebetween that stores water to prevent further ingress of water vapor. Because the lamp cap sleeve 1310 has elasticity, and the lamp cap sleeve 1310 is expanded when being sleeved on the lamp cap 300 and the lamp tube 100 to generate an elastic restoring force, the elastic restoring force can force the sealing ring 1316 to be tightly attached to the outer circumferential surface of the lamp tube 100, so as to generate a better airtight or waterproof effect, and make it more difficult for external liquid or water vapor to pass through between the sealing ring 1316 and the lamp tube 100 and enter the waterproof lamp cap 1300.

In some embodiments, the diameter of the base sleeve 1310 need not be smaller than the diameter of the base 300 and the lamp 100, since the inner circumference of the base sleeve 1310 has the sealing ring 1316. Conversely, the diameter of the lamp holder sleeve 1310 may be about equal to or slightly larger than the diameter of the lamp holder 300 and the lamp tube 100, even though the sealing ring 1316 may still be attached to the outer circumference of the lamp tube 100 when the lamp holder sleeve 1310 is properly sleeved on the lamp holder 300 and the lamp tube 100, thereby generating a certain degree of airtight or waterproof effect. Moreover, since the caliber of the lamp holder sleeve 1310 is not smaller than the diameters of the lamp holder 300 and the lamp tube 100, the user can move the waterproof lamp sleeve 1300 along the axial direction and want to make the waterproof lamp sleeve 1300 sleeve-connected with the lamp holder 300 and the lamp tube 100, which is simpler.

In the present embodiment, the number of the sealing rings 1316 is three, and the sealing rings 1316 are disposed at positions corresponding to the second annular protrusion 1312 in the radial direction, but not limited thereto. For example, two of the outer sides of the three sealing rings 1316 are respectively adjacent to the second annular protrusion 1312, and the middle one of the three sealing rings 1316 is adjacent to the second receiving groove 1314. When the hanging rope or the hanging strap for hanging the straight tube lamp 50 is tied around the second receiving groove 1314, the component of the hanging rope or the hanging strap for tightening the straight tube lamp 50 is converted into a pressure applied to the sealing ring 1316, particularly the sealing ring 1316 located in the middle and adjacent to the second receiving groove 1314, so that the sealing ring 1316 can be more tightly attached to the lamp tube 100, and the air-tight or water-proof effect between the sealing ring 1316 and the lamp tube 100 is better.

As shown in fig. 4 and 5, in the present embodiment, at least one annular seal ring 1331 is further integrally formed on the inner circumferential surface of the wire sleeve 1330.
