The invention discloses an LED (light-emitting 
diode) 
lawn lamp using a support composite member as a mounting interface. The LED 
lawn lamp comprises the support composite member, wherein the support composite member is provided with a water-proof and dust-proof LED 
bulb (102) with a radiator; a lamp cover module molded by 
metal stamping or molded by plastic 
die casting is covered outside the support composite member; and the support composite member is mounted on a lamp fixing 
flange (106). According to the LED 
lawn lamp disclosed by the invention, the support composite member is used as a mounting fixing member and provides the mounting interface for the 
bulb, and the lamp cover module, the LED 
bulb and other auxiliary members are all integrated on the support composite member, therefore, the LED lawn lamp is simple in structure, low in cost and convenient to 
mount, use and maintain. The LED lawn lamp disclosed by the invention is independent in production and use, so that production links of LED lighting product can be greatly reduced, 
mass production is improved, standard large-scale production is easy to realize, and LED energy-saving lighting product can be facilitated in industrialization.
