Detailed ways

The LED floodlight includes the floodlight housing, LED light source module, driving power supply, lamp glass, reflective bowl, etc. The main improvement of the utility model lies in the installation method and structure of the LED light source module, so it is not shown in the figure. For the complete structure of LED floodlights, only the structures related to the utility model points are described in the text.

Referring to FIG. 1 and FIG. 2 , the LED light source module 2 and the pressure plate 3 are installed at the center of the flat inner wall of the floodlight housing 1 . The LED light source module 2 is a light-emitting component of the LED floodlight, including a substrate and a plurality of LED chips arrayed on the substrate. Referring to FIG. 3 , there are two electrode plates 21 on the LED light source module 2 , and the electrode plates 21 are electrically connected to the LED chip, and the material of the electrode plates 21 is copper, gold or silver with good conductivity. Some positioning structures, such as grooves or bumps, can be provided on the floodlight housing 1 to realize the installation and positioning of the LED light source module 2 , and then use the pressure plate 3 to fix the LED light source module 2 . It is also possible to directly fix the LED light source module 2 on the housing 1 of the floodlight. For example, in this embodiment, the LED light source module 2 is fixed on the plane of the housing 1 of the floodlight with a rivet. The LED light source module 2 is closely attached to the plane of the floodlight housing 1 and is the heat conduction substrate on the back. The heat conduction substrate is mainly used for heat dissipation, and its material is selected from aluminum or copper with good heat conductivity. In order to enhance the heat dissipation effect of the LED light source module 2 , before installing the LED light source module 2 on the floodlight housing 1 , evenly apply heat-conducting silicone grease on the heat-conducting substrate.

Referring to FIG. 4 , the pressing plate 3 is generally a rectangular thin plate with a rectangular through hole at its center and a groove 31 on its left and right walls. Referring to Fig. 1 and Fig. 2, the pressure plate 3 is pressed on the LED light source module 2, and the LED light source module 2 is firmly pressed on the floodlight housing 1. The LED chip of the LED light source module 2 is in the through hole of the pressure plate 3, and the groove 31 is in the position facing the electrode disc 21. Some positioning structures, such as grooves or bumps, can be provided on the floodlight housing 1 to realize the installation and positioning of the pressure plate 3 . The pressing plate 3 is fixedly installed on the floodlight housing 1 by a rivet, and the pressing plate 3 can also be detachably installed by other installation methods.

Referring to FIG. 1 and FIG. 2 , the insertion piece 4 is inserted into the groove 31 of the pressure plate 3 . The insertion piece 4 has a barb 41 and an elastic piece 42 at one end, and the end of the barb 41 has serrations. The insertion piece 4 is made by stamping a metal sheet with good electrical conductivity and elasticity, and both the barb 41 and the shrapnel 42 are elastic. The elastic piece 42 is tightly pressed on the electrode disk 21 , and its elasticity enables it to maintain good electrical contact with the electrode disk 21 . The wire 5 is inserted into the insert 4, and the barb 41 clamps and locks the wire 5, and is in good contact with the copper core of the wire 5, and the wire 5 is connected with the electrodes of the driving power supply.
