Description

Technical Field

[0001] The utility model relates to the field of lifesaving, in particular to a light source component of a visual distress signal lamp. Background Art

[0002] In the field of lifesaving, visual distress signal lights are critical. Visual distress signal lights can emit flashing light signals to facilitate people to find trapped people; especially on ships, they are equipped with visual distress signal lights.

[0003] Existing visual distress signal lights generally include a light source component and a power supply component. The power supply component and the light source component are detachable and matched, so that the battery module of the power supply component is detachable, which makes it easy for people to quickly provide power to the visual distress signal lights by replacing the battery module. The light source component of the existing visual distress signal lights generally uses a light source board with LED lamp beads to emit light. This light source board with LED lamp beads generates a large amount of heat when working, and the existing visual distress signal lights generally dissipate heat by setting a heat sink in contact with the light source in the housing of the light source component. This heat dissipation method cannot quickly export the heat generated by the light source board to the external environment, so the heat dissipation effect is not good, which greatly affects the light emitting effect and service life of the LED lamp beads of the light source board.

[0004] In view of the above problems, it is necessary to study a light source assembly of a visual distress signal light, which has the advantage of good heat dissipation effect. Utility Model Content

[0005] The utility model aims to provide a light source assembly of a visual distress signal light, which has the advantage of good heat dissipation effect.

[0006] In order to achieve the above purpose, the solution of the utility model is:

[0008] The upper cover is provided with a retaining ring, the upper cover is connected to the base, and the edge of the lampshade and the edge of the heat dissipation seat are clamped between the retaining ring of the upper cover and the end of the base.

[0009] The upper cover and the base are fixed by screws.

[0010] Sealing rings are sandwiched between the lampshade and the upper cover, and between the upper cover and the base.

[0011] The heat sink is located between the light source board and the main control board, the light source board is clamped between the lampshade and the heat sink, the heat sink is provided with a contact portion for resisting the light source board, the light source board and the main control board are connected by at least two connectors passing through the heat sink, and a support column is clamped between the heat sink and the main control board.

[0012] The number of the support columns is the same as the number of the connecting pieces, and each support column is respectively sleeved with each connecting piece.

[0013] The connecting piece is a screw, which passes through the light source board and the heat sink in sequence and is then locked with the main control board.

[0014] The light source board and the main control board are electrically connected via connecting wires passing through the heat sink.

[0015] The outer side of the base is equipped with a control switch electrically connected to the main control board.
