Embodiment

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the LED point light source of the present embodiment, including the bottom case 1 and mask 2 that can be covered, bottom case 1 and face Pcb board 3 is installed in the closing chamber of cover 2, runs through on bottom case 1 and is connected with rubber cable 4, rubber cable 4 is electrically connected with pcb board 3, Rubber cable 4 and the through part of bottom case 1 are provided with waterproof apron 7, and the bottom of bottom case 1 is blocked by plug 8, plug 8 and bottom case 1 Plug cushion rubber 9 is installed between bottom；Pcb board 3 is provided with light trap 5 close to the side of mask 2, light trap 5 have with The corresponding loophole 51 of LED light 31 and positioned at 51 edge of loophole, the arc-shaped cover 52 perpendicular to pcb board 3 on pcb board 3.

As shown in figure 5, being provided with multiple LED light 31 on pcb board 3, light trap 5 includes the bottom plate 50 being bonded with pcb board 3 And protrusion is arranged at the arc-shaped cover 52 of 50 side of bottom plate, has loophole 51 corresponding with each LED light 31 on bottom plate 50, each The direction of the cancave cambered surface 520 of arc-shaped cover 52 corresponding with LED light 31 is identical, i.e., towards side.

To realize more preferable spotlight effect, as shown in Figure 6, Figure 7, the central shaft A of arc-shaped cover 52 and the central shaft of LED light 31 There is eccentric distance, the eccentric distance is 0.5mm between B.

To ensure to form the installation space of sealing between bottom case 1 and mask 2, as shown in Figure 3, Figure 4, bottom case 1 and mask 2 it Between be spiral connection, bottom case 1 at the end contact of mask 2 with being provided with sealing ring 6.Further, the upper end periphery of bottom case 1 With a circle step 10, step 10 is equipped with a circle mounting groove 11, and sealing ring 6 is installed in mounting groove 11.As shown in figure 8, for into One step improves sealing effect, and the sealing ring 6 of the utility model is silica gel material, and symmetrically protrusion is equipped with for the both sides up and down of sealing ring 6 Ring rib 61, ring rib 61 include inside and outside multi-turn so that it forms labyrinth seal knot with the contact surface of bottom case 1 and mask 2 Structure.
