[0035] The light emitting element on the light source board 2 is used for lighting. In some preferred embodiments, the light emitting element is a light emitting diode. The power cord 14 enters the inner side of the lamp trough 1 through the line inlet 3 and is electrically connected to the light source board 2 to supply power to the light source board 2. Figure 3 As shown, the slot cover 4 is provided with a light outlet 5 , which surrounds the light emitting elements on the light source board 2 in the middle, and the light emitting elements on the light source board 2 emit light to the outside through the light outlet 5 .

[0036] Furthermore, in some embodiments, sealant is filled between the line inlet 3 and the power line 14 to achieve a sealed connection.

[0037] Furthermore, in some other embodiments, the lamp trough 1 is provided with a wire inlet groove 10, the wire inlet port 3 is connected to the side wall of the wire inlet groove 10, and the wire inlet groove 10 and the wire inlet port 3 and the power line 14 are filled with sealant to achieve a sealed connection. The sealant may be glue or epoxy resin.

[0038] In some embodiments, the light-transmitting plate 6 is made of glass. The edge of the light-transmitting plate 6 and the edge of the slot cover 4 are sealed and bonded to the slot of the lamp slot 1 by glue.

[0039] The present application fills sealant in the wire inlet groove 10 and between the wire inlet port 3 and the power cord 14. The edge of the light-transmitting plate 6 and the edge of the groove cover 4 are sealed and bonded to the groove of the lamp trough 1 by glue, thereby achieving a sealed connection to prevent external moisture from entering the lamp trough 1.

[0040] The following is combined with the appendix of this manual Figures 1 to 5 , the preferred implementation modes of the present disclosure are further elaborated in detail.

[0041] According to some embodiments, Figure 3 , Figure 5 As shown, the slot cover 4 includes a lamp frame 7 and a cover plate 8, a through opening is opened in the middle of the cover plate 8, the light outlet 5 is arranged in the middle of the lamp frame 7, the outer side of the lamp frame 7 is connected to the through opening, and the inner side of the lamp frame 7 is used to enclose the light-emitting elements on the light source board 2.

[0042] Among them, Figure 3 , Figure 5 As shown, the light outlet 5 is arranged in the middle of the lamp frame 7, and the inner side of the light outlet 5 is used to enclose the light-emitting element on the light source board 2. The inner side of the light outlet 5 is smaller than the outer side of the light outlet 5, and the inner side is connected with the outer side to increase the illumination range of the light-emitting element on the light source board 2 to the outside. The distance between the inner side of the light outlet 5 and the outer side of the light outlet 5 is determined according to the height of the electronic components on the light source board 2.

[0043] According to some embodiments, Figure 1 to Figure 2 As shown, the floodlight further comprises a bracket 9, and two ends of the bracket 9 are rotatably connected to two ends of the outer side of the lamp trough 1.

[0044] Further, such as Figure 4 As shown, the lamp trough 1 is also provided with a connection groove 11, and the connection groove 11 and the wire inlet groove 10 are both arranged at the bottom of the lamp trough 1, and nuts are connected to the outer sides of the connection groove 11 and the outer sides of the wire inlet groove 10. Figure 3 As shown, two ends of the bracket 9 are connected and fixed to the lamp trough 1 by screws and nuts.

[0045] Among them, Figure 3 As shown, the bracket 9 is in a concave shape, and through holes are opened at both ends of the bracket 9. The two ends of the bracket 9 are placed on the nuts at the two ends of the outer side of the lamp trough 1, so that the axis of the nut coincides with the axis of the through hole. Then, screws are passed through the through holes and threadedly connected with the nuts, so that the two ends of the bracket 9 are respectively connected and fixed with the nuts at the two ends of the outer side of the lamp trough 1.

[0046] Further, such as Figure 1As shown, when the bracket 9 is rotated and retracted, the bracket 9 is sleeved on the lamp trough 1 and closely attached to the outer side of the lamp trough 1, so as to facilitate carrying and save space.

[0047] Further, the support 9 can be made of Figure 1 The folded state is rotated to any angle between 0 and 180 degrees, such as Figure 2 As shown, Figure 2 This is the case when the bracket 9 rotates to 180 degrees. The rotation steps may be to first loosen the screws so that the bracket 9 can rotate, then rotate the bracket 9 to a suitable angle, and then tighten the screws so that the bracket 9 cannot rotate, thereby fixing the lighting angle of the floodlight.

[0048] Furthermore, a plurality of fixing holes 12 are provided in the middle of the bracket 9 for fixing at a desired position, such as a wall or a ceiling.

[0049] In some embodiments, Figure 3 to Figure 4 As shown, in order to facilitate the sealing and bonding of the edge of the light-transmitting plate 6 and the edge of the slot cover 4 to the slot of the lamp trough 1 by glue, the present application connects a plurality of limit blocks 13 on the inner side of the slot of the lamp trough 1. If the light-transmitting plate 6 and the slot cover 4 are placed in the slot of the lamp trough 1, the edges of the light-transmitting plate 6 and the slot cover 4 are just held by the plurality of limit blocks 13 and cannot move left and right or up and down, so that a gap is reserved between two consecutive limit blocks 13, and the gap is just convenient for filling with glue.

[0050] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
