[0011] The present invention describes a combined high-heat-dissipation downlight. When the downlight body is working, it generates heat. This heat is effectively absorbed by the heat-absorbing plate and transferred to the heat-absorbing liquid. The heat-absorbing liquid, as a heat conduction medium, can quickly conduct heat from the downlight body to the cavity of the outer edge plate of the downlight. Then, the heat is transferred and diffused to the outside air through the outer edge plate of the downlight, which improves the heat dissipation efficiency, helps to maintain the stable operation of the downlight, and extends its service life.

[0012] The present invention describes a combined high heat dissipation downlight in which the deformable metal in the groove deforms after absorbing sufficient heat, thereby agitating the heat-absorbing liquid in the groove and promoting heat convection inside the liquid, thus further accelerating the transfer and dissipation of heat.
