The positioning plate 21 is attached on the heat sink 10 and includes a receiving room 211 for receiving the COB module 30 therein, and the COB module 30 is attached on the heat sink 10. A size of the receiving room 211 is adapted to that of the COB module 30. The double-sided aluminum substrate 22 is pressed onto the positioning plate 21 and the COB module 30. The lens 50 is arranged on the double-sided aluminum substrate 22 and configured to control an angel that light is emitted from the COB module 30.

[0015] A pair of conductive protrusions 221 is arranged on a side of the double-sided aluminum substrate 22 facing the COB module 30. The pair of conductive protrusions 221 is directly opposite to a positive electrode 31 and a negative electrode 32 of the COB module 30, and is respectively connected to the positive electrode 31 and the negative electrode 32 of the COB module 30, so that the COB module 30 is electrically connect to the double-sided aluminum substrate 22. In an embodiment of the present disclosure, there are at least two locking elements 40 passing through the double-sided aluminum substrate 22 and the positioning plate 21 to fix all of the double-sided aluminum substrate 22, the COB module 30 an the positioning plate 21 to the heat sink 10. The locking element 40 can be a locking nut. The pair of conductive protrusions 221 of the double-sided aluminum substrate 22 is respectively pressed onto the positive electrode 31 and the negative electrode 32 of the COB module 30 to electrically connect the COB module 30 and the double-sided aluminum substrate 22.

It is not necessary to use wires to connect the COB module and the substrate through welding wires on the market, which can avoid an adverse phenomenon of thermal expansion and contraction from being occurred on colloid of the COB module 30 during welding the COB module 30, thereby improving the lifespan of the COB module 30 and a yield rate of products, reducing production costs thereof. And then, the present disclosure can reduce energy consumption of welding the COB module 30 and is more energy-efficient and environmentally friendly.

[0016] In an embodiment of the present disclosure, a first through-hole 222 is formed at a middle portion of the double-sided aluminum substrate 22 and directly faces the COB module 30. By setting the first through-hole 222, the light emitted from the COB module 30 can ' t be blocked. It should be noted that in the embodiment of the present disclosure, a size of the first through-hole 222 is slightly smaller than that of the COB module 30, so that the double-sided aluminum substrate 22 can press onto the COB module 30.

[0017] In an optical embodiment of the present disclosure, the double-sided aluminum substrate 22 includes two ear portions 223, the pair of conductive protrusions 221 respectively arranged on one of the two ear portions 223. There are also two grooves 224 arranged on two sides of the ear portion 223. The two ear portions 223 and the two grooves 224 are provided to make the two ear portions 223 have a certain elasticity. When the pair of conductive protrusions 221 abuts against the positive electrode 31 and the negative electrode 32 of the COB module 30, the two ear portions 223 will slightly lift upwards. Therefore, the two ear portions 223 can generate and continue to have a certain compression force downwards to press the pair of conducive protrusions 221 of the two ear portions 223 against the positive electrode 31 and the negative electrode 32 of the COB module 30, so as to ensure connection stability between the pair of conducive protrusions 221 and the positive electrode 31 and the negative electrode 32 of the COB module 30, and avoid poor connection therebetween.

Two retaining lugs 51 and two clamping portions 52 are arranged on a side of the lens 50 close to the double-sided aluminum substrate 22. In an embodiment of the present disclosure, each of the double-sided aluminum substrate 22 and the positioning plate 21 is circular. The two second through-holes 225 and the two card portions 226 are uniformly arranged around an axis of the double-sided aluminum substrate 22, and the two second through-holes 225 and the two card portions 226 are cross arranged. The two retaining lugs 51 of the lens 50 respectively correspond to the two second through-holes 225, and the two clamping portions 52 of the lens respectively correspond to the two card portions 226. A positioning portion 227 is arranged on a middle portion of the second through-hole 225 and configured to position the retaining lug 51 of the lens 50. A length of the second through-hole 225 is twice a length of the retaining lug 51.

Two third through-holes 212 are arranged on the positioning plate 21 and corresponding to the two card portions 226, which serves as a moving accommodating cavity for the clamping portion 52 of the lens 50. The card portion 226 includes a first groove 2261 and a second groove 2262. A width of the first groove 2261 is smaller than that of the second groove 2262, so that an overall shape of the card portion 226 is similar to an L-shape. When installing the lens 50, first the two clamping portions 52 of the lens 50 are inserted into the second grooves 2262. At this time, the two retaining lugs 51 of the lens 50 are inserted into one end of the two second through-holes 225, and then the lens 50 rotates to drive the two clamping portions 52 of the lens 50 to rotate, so that the two clamping portions 52 of the lens 50 can be inserted into the double-sided aluminum substrate 22 that is formed at an edge position A of the first groove 226. And at this time, the two retaining lugs 51 of the lens 50 rotate to the other end of the second through-hole 225, and the positioning portion 227 precisely catches on the retaining lug 51 of the lens 50.
