Referring to FIG. 1, an LED linear lamp 100 according to a preferred embodiment of the present invention includes a cylindrical lamp tube 1 and a lamp cap 2 disposed at both ends of the lamp tube 1. The lamp tube 1 is hollow and is made of a light diffusing material, and houses an LED lamp panel (not shown) arranged along the longitudinal extension direction of the bulb 1 and a supporting member for supporting the LED panel (not shown). The support member is supported under the LED light panel along the extending direction of the LED light panel and simultaneously provides a heat dissipation function for the LED light panel.

Referring to FIGS. 6 , the base 2 includes a first base 21 that is fixedly coupled to both ends of the tube 1 and a second base 22 that is detachably coupled to the first base 21 .

Each of the first bases 21 has a hollow cylindrical housing 210 and a bottom wall 212 disposed in a vertical plane adjacent the end of the tube 1, which substantially encloses one end of the outer casing 210. The hollow cylindrical housing 210 defines a first receiving space 211. A plurality of support structures 213 are defined in the interior of the housing 210 for supporting a driving power source (not shown). The driving power source is electrically connected to the LED panel in the lamp tube 1 and supplies power to the LED panel. A plurality of first latching portions 214 are protruded from the first receiving space 211 at a position adjacent to the other end of the housing 210. Preferred in the present invention In the embodiment, the first holding portions 214 are four, which are arranged along the circumferential direction of the inner surface of the housing 210 and are along the axial direction of the outer casing 210 (ie, the extending direction or the axial direction of the bulb 1). Gradually increasing, a wedge shape is formed, and a block 2140 is formed extending circumferentially at the maximum height. The first base 21 passes through the bottom wall 212 through a pair of screws 3 and is locked to the supporting member housed in the bulb 1 to form a fixed connection relationship between the first cap 21 and the bulb 1.

Each of the second bases 22 includes a hollow cylindrical body portion 220 and an end wall 222 disposed in a vertical plane at an end thereof away from the second base 22, the end wall 222 closing one end of the body portion 220. The main body 220 and the end wall 222 define a second receiving space 221 having an opening facing the first base 21 . The second receiving space 221 houses a connecting plate 4 and a fuse 5 electrically connected to the connecting plate 4 . A pair of pin-shaped conductive terminals 7 are disposed outside the end wall 222, which are electrically connected to an external power source and provide power to the LED linear lamp 100 of the present invention. The conductive terminals 7 can be formed integrally with the end wall 222 or integrally formed with the end wall 222 and partially protrude into the second receiving space 221 to form an electrical connection with the connecting plate 4 . The inner surface of the end wall 222 protrudes toward the second receiving space 221 to form a pair of columnar protrusions 2222. A cross-shaped connecting portion 2223 is formed between the columnar protrusions 2222, and a positioning portion 2221 is formed to protrude from the upper portion of the connecting portion 2223 toward the second receiving space 221. From the other end edge 223 of the main body portion 220 of the second base 22, a plurality of second latching portions 224 extending beyond the second receiving space 221 are formed in the direction of the first base 21 . In a preferred embodiment of the present invention, the second holding portions 224 are four, which are respectively arranged along the circumferential direction of the main body portion 220 of the second second base 22 and along the axial direction of the main body portion 220 (ie, the lamp tube 1). The axial direction or its extension direction is extended. Each of the second fastening portions 224 has a curved plate-like structure, and a rectangular receiving hole 2240 is defined in the middle portion. The outer diameter of the main body portion 220 of the second base 22 is flush with the outer surface of the second latching portion 224 and smaller than the inner diameter of the housing 210 of the first base 21, so that when the first base 21 and the second base 22 are assembled, The second latching portion 224 of the second cap 22 slides along the surface of the wedge-shaped first latching portion 214, and finally engages with the first latching portion 214. The receiving hole 2240 of the second latching portion 224 receives the first latching portion. The block 2140 of 214 forms a detachable connection between the first base 21 and the second base 22.

Removable connection. At this time, it is only necessary to arrange the inner diameter of the second base 22 to be larger than the outer diameter of the first base 21.

A second connecting space 221 of each of the second bases 22 houses a connecting plate 4, which is a flat circuit board. One of the connecting plates 4 has a wire (not shown) connected to the driving power source housed in the first base 21, so that the mains is electrically connected to the conductive terminal 7 after being connected from the conductive terminal 7 of the second base 22 The connection board 4 in turn supplies power to the drive power source. The electrical connection relationship between the connecting plate 4 and the conductive terminals 7 of the second base 22 is the same as that of the other connecting plate 4, which will be described in detail below.

The middle portion of the upper portion of the other connecting plate 4 is provided with a positioning groove 41 extending downward from the upper end edge thereof. The positioning portion 2221 of the second lamp cap 22 passes through the positioning groove 41 to properly mount the connecting plate 4. A pair of through holes 42 are formed in the middle of the connecting plate 4, and the pair of through holes 42 are coated with a conductive material such as copper. A pair of screws 6 respectively pass through the pair of through holes 42 and are electrically connected to the conductive material laid in the through hole 42 and further lock into the columnar protrusions 2222 of the second lamp cap 22 and further contact with the conductive terminals 7 to form a commercial power. Electrical connection to the conductive terminal 7 and to the connection board 4. The pair of screws 6 are preferably made of a copper alloy material containing 50% or more of copper, which can serve as a current-carrying member and fix the connecting plate 4 to the second base 22 . The material of the screw 6 is not limited to the copper alloy described above, and materials satisfying the requirements as a current-carrying member are included in the scope of the present invention. A pair of openings 43 are defined in the lower portion of the connecting plate 4, and the opposite opening 43 is also provided with a conductive material, such as copper, which is electrically connected to the through hole 42 through a line disposed in the connecting plate 4, so that the fuse 5 is After the pair of pins 51 pass through the pair of holes 43, respectively, they are electrically connected to the connecting plate 4. Since the presence of the fuse 5 is short-circuited between the pair of conductive terminals 7, the commercial power is mainly supplied from the other second base 22. In the case where the LED linear lamp 100 is reversed to the mains, in order to protect the LED linear lamp 100 from being damaged by current breakdown, the fuse 5 is first burned to protect the LED linear lamp 100. By adopting the structure of the fuse 5 separately provided on the connecting plate 4, when the fuse 5 is broken, as long as the screw 6 is loosened, the connecting plate 4 with the fuse can be replaced. It greatly simplifies the process and saves time.
