[0014] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. It should be noted that the description of these implementations is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0015] See also Figure 1 , the figure shows a mast light for a ship. The mast light for a ship comprises: a lamp housing component 1, a lampshade component 2, a protective cover component 3, a light source component 4, a light shield component 5 and the like.
[0016] The lamp housing component 1 has a lamp housing top wall and a lamp housing side wall. The lamp housing top wall and the lamp housing side wall together define a lamp housing internal space with a downward opening. The downward opening is sealed by a cover plate 8. Preferably, a seal is provided between the cover plate 8 and the lamp housing side wall.
[0017] The built-in space of the lamp housing contains a power module 6 and a control module 7. The power module 6 is fixed on the top surface of the cover plate 8. The power module 6 is electrically connected to a waterproof sealing connector 9 passing through the cover plate 8. The control module 7 is fixed on the bottom surface of the top wall of the lamp housing. The control module 7 is used to control the light source component 4. A top wall boss is formed on the top surface of the top wall of the lamp housing.
[0018] The lampshade component 2 is above the lamp housing component 1. The lampshade component 2 has a lampshade main body and a lampshade outward flange, etc. The lampshade main body is a bell-shaped structure. The lampshade main body surrounds the outer side of the top wall boss. The inner circumference of the lampshade main body abuts against the outer circumference of the top wall boss. A seal 100 is provided between the inner circumference of the lampshade main body and the outer circumference of the top wall boss. The seal 100 is, for example, a sealing ring inside a groove formed on the outer circumference of the top wall boss. The lampshade outward flange is formed at the lower edge of the lampshade main body. The lampshade outward flange extends outward from the lower edge of the lampshade main body. The lampshade outward flange is above the top wall of the lamp housing. A seal 200 is provided between the lampshade outward flange and the top wall of the lamp housing. The seal 200 is, for example, a sealing ring between the lampshade outward flange and the top wall of the lamp housing.
[0019] The protective cover component 3 is used to protect the lampshade component 2. The protective cover component 3 surrounds the outer side of the lampshade component 2. The protective cover component 3 has a protective cover body, an inwardly turned edge of the protective cover, and a downwardly turned edge of the protective cover. The protective cover body is a bell-shaped structure. The inwardly turned edge of the protective cover is formed at the lower edge of the protective cover body. The inwardly turned edge of the protective cover extends inward from the lower edge of the protective cover body. The inwardly turned edge of the protective cover is above the outwardly turned edge of the lampshade. A seal 300 is provided between the inwardly turned edge of the protective cover and the outwardly turned edge of the lampshade. The seal 300 is, for example, a sealing ring between the inwardly turned edge of the protective cover and the outwardly turned edge of the lampshade. The downwardly turned edge of the protective cover is formed at the lower edge of the protective cover body. The downwardly turned edge of the protective cover surrounds the outwardly turned edge of the lampshade and the outer side wall of the lamp housing. The inner circumference of the lower edge of the protective cover abuts against the outer circumference of the side wall of the lamp housing, so that the inward flange of the lamp housing, the seal between the inward flange of the protective cover and the outward flange of the lamp housing, and the seal between the outward flange of the lamp housing and the top wall of the lamp housing are sealed in the space enclosed by the inward flange of the protective cover, the lower edge of the protective cover and the top wall of the lamp housing, so as to ensure the sealing ability.
[0020] Preferably, the inwardly turned edge of the protective cover presses down the outwardly turned edge of the lamp cover to tighten the seal between the inwardly turned edge of the protective cover and the outwardly turned edge of the lamp cover and the seal between the outwardly turned edge of the lamp cover and the top wall of the lamp housing.
[0021] See also Figure 1 , Figure 2 and Figure 3 , the figure shows the light source component 4. The light source component 4 is above the lamp housing component 1. The light source component 4 has a light source fixing seat 41 and a light source printed circuit board 42. The light source fixing seat 41 has a fixing seat bottom plate 411 and a fixing seat column 412. The fixing seat bottom plate 411 is fixed to the top surface of the top wall boss by screws. The cross-section of the fixing seat column 412 is a regular hexagonal structure. The fixing seat column 412 has a first side surface of the column, a second side surface of the column, a third side surface of the column, a fourth side surface of the column, a fifth side surface of the column and a sixth side surface of the column arranged in sequence along the circumferential direction. Among them, the first side surface of the column, the second side surface of the column, the third side surface of the column and the fourth side surface of the column are all configured with the light source printed circuit board 42, while the fifth side surface of the column and the sixth side surface of the column are not configured with the light source printed circuit board 42.
[0022] Preferably, the light source printed board 42 has a main LED 43 and a backup LED 44. The main LED 43 is on the top and the backup LED 44 is on the bottom. When the light source printed board 42 works normally, the main LED 43 works and the backup LED 44 does not work. If the main LED 43 fails, the backup LED 44 is enabled to work instead of the main LED 43.
[0023] Preferably, the fixing seat column 412 is a hollow structure, in order to improve the heat dissipation capacity and facilitate the entry and exit of wires.
[0024] See also Figure 1 and Figure 4 , the light shield component 5 is shown in the figure. The light shield component 5 is inside the lampshade component 2. The light shield component 5 is used to limit the light output angle of the light source component 4 (mainly to limit the lateral light output of the light source component 4). The light shield component 5 has a light shield top wall 51 and a light shield surrounding wall 52 below the light shield. The light shield top wall 51 is above the fixed seat column 412. The light shield top wall 51 is fixed to the top surface of the fixed seat column 412 by screws. The light shield surrounding wall 52 is outside the fixed seat column 412 and on the fifth side surface of the column and the sixth side surface of the column, that is, the light shield surrounding wall 52 limits the light output of the light source component 4 to the fifth side surface of the column and the sixth side surface of the column, so as to meet the light performance requirements of the CB518-2005 standard mid-mast lamp. The light shield surrounding wall 52 is embedded in the groove 4110 formed by the fixed seat bottom plate 411.
[0025] The above only expresses the implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
