Referring to fig. 4 to 9 together, since the two side LED substrates 320 are bent and enclosed relative to the end LED substrate 310 and do not have a fixed state, but still have a loose state, specifically, the positions of the two first side plates 321 and the two third side plates 323 on the two sides of the end LED substrate 310 after being bent and enclosed, namely, the positions indicated by 315 in fig. 9, therefore, in order to prevent the two side LED substrates 320 from loosening after assembly, the baffle plates are correspondingly provided, and include V-shaped inner baffle plates 224 and outer baffle plates 225, the inner baffle plates 224 and the outer baffle plates 225, and the inner baffle plates 224 and the outer baffle plates 225 are used for clamping and positioning the enclosed positions 315 (see fig. 9) of the bent side LED substrates 320, so that the tubular illuminant 300 cannot be dispersed without adopting welding or fastening, if welding and fastening are adopted, the assembly of the lamp 10 is complicated, and the fastening structure is required to be designed.
As shown in fig. 11, the power supply case 200 includes a housing bin 201, and a wire passing hole 226 and a positioning column 203 disposed at the bottom of the housing bin 201, wherein the housing bin 201 is used for housing the power supply module 202, the wire passing hole 226 is used for receiving a wire to pass through so as to electrically connect the power supply module 202 with the cylindrical light emitting body 300, and the positioning column 203 is used for positioning and mounting the power supply module 202.
The outer surface of the connecting part 230 is provided with a connecting thread 231 and a positioning groove 232, the connecting thread 231 is used for connecting the lamp cap 400, the positioning groove 232 is used for positioning and assembling the adapter sleeve 410, and the adapter sleeve 410 can cover the joint of the housing body 100 and the power supply shell 200.
The invention also provides a lamp 10, which lamp 10 comprises the aforementioned power supply housing 200.
In summary, those skilled in the art will readily understand that the lamp 10, the light source substrate 300 and the power source housing 200 provided by the invention have the advantages of simple structure, good heat dissipation, convenient manufacture, no need of welding or fastening connection of the light source substrate 300, easy assembly, and greatly reduced production difficulty and cost.
The foregoing is only illustrative of the present invention and is not to be construed as limiting the scope of the invention, and all equivalent structures or equivalent flow modifications which may be made by the teachings of the present invention and the accompanying drawings or which may be directly or indirectly employed in other related art are within the scope of the invention.
