Embodiment
[0050] Such as Figure 4 , 5 As shown, the LED light bar of the present invention includes a heat dissipation bracket 201 , a light board 202 on which an LED light source 204 is fixed, and a semicircular light output cover 203 .
[0051] Such as Figure 6 As shown, the heat dissipation bracket 201 includes a heat dissipation groove 205 and a fixing bar 206. The heat dissipation groove 205 and the fixing strip 206 are designed in an integrated manner, and are made of a mixture of rare earth and aluminum, specifically composed of the following components by mass percentage:
[0052] Mg 0.4%~1%,
[0053] Si 0.7%~18%,
[0054] Mn 0.12%~0.2%,
[0055] Cr 0.12%~0.2%,
[0056] Cu 0.12%~0.2%,
[0057] Fe 0.12%~0.2%,
[0058] Ti 0.12%~0.2%,
[0059] Re 0.1%~0.2%,
[0060] Al balance.
