DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the drawings and specific embodiments of the specification. A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. In addition, the embodiments of the utility model involved in the following description are usually only embodiments of a part of the utility model, rather than all of the embodiments. Therefore, based on the embodiments in the utility model, all other embodiments obtained by a person of ordinary skill in the art without making creative work should fall within the scope of protection of the utility model.

[0023] Reference Figure 1 , 2 : This RV porch light includes a light-emitting device 2 and a shell 1 for protecting the light-emitting device 2. The light-emitting device 2 includes a fixing seat 3 installed in the shell 1, a light-emitting circuit board 4 installed on the fixing seat 3, and a focusing bar 5 is installed on the outer surface of the light-emitting circuit board 4. A plurality of LED light sources capable of emitting light are arranged on the light-emitting circuit board 4. The LED light sources are distributed at intervals on the outer surface of the light-emitting circuit board 4. The focusing bar 5 is provided with a plurality of focusing holes 23 distributed at intervals to improve the brightness of the light. Specifically, the focusing hole 23 is an elliptical opening arranged on the focusing bar 5 and passing through the focusing bar 5. Each LED light source is covered with a focusing hole 23. Refer to the attached Figure 2 : The plurality of focusing holes 23 in this embodiment are elliptical openings of the same size and shape. A protective cover 6 for protecting the focusing bar 5 is detachably mounted on the focusing bar 5. A plurality of inwardly protruding and evenly distributed clips 7 are arranged around the protective cover 6. A clip strip 8 that cooperates with the clip 7 to clip the fixing seat 3 is provided. Specifically, the clip 7 in this embodiment is an "L"-shaped detachable buckle. When the clip 7 is installed on the clip strip 8, the clip 7 will produce a certain deformation so that the top of the clip 7 is clipped onto the clip strip 8. In order to The operator can easily clip the clip 7 onto the clip strip 8. An opening 9 is provided at the connection between the clip 7 and the protective cover 6 to facilitate the clip 7 to be clipped into the clip strip 8. The opening 9 reduces the contact area of ​​the connection between the clip 7 and the protective cover 6. Due to the provision of the opening 9, the connection between the clip 7 and the protective cover 6 is only left at the left and right sides of the opening, which improves the toughness of the connection between the clip 7 and the protective cover 6, so that the clip 7 can be deformed to a certain extent when being clipped, thereby facilitating the clip 7 to be clipped to the outside of the clip strip 8.

[0024] Reference Figure 5 : Among them, the protective cover 6 includes a connecting portion 18 connected to the fixing seat 3 and a receiving groove 10 for protecting the focusing bar 5. The connecting portion 18 is arranged on the outer periphery of the receiving groove 10, and the receiving groove 10 protrudes from the connecting portion 18. The protective cover 6 is made of a transparent material. The transparent protective cover 6 protects the focusing bar 5 while not affecting the brightness of the light generated by the light-emitting circuit board 4 located inside the focusing bar 5. After the light-emitting device 2 is installed inside the shell 1, in order not to affect the brightness and irradiation area of ​​the light-emitting device 2, a light-emitting groove 19 matching the size of the receiving groove 10 is provided on the shell 1. At the same time, since the RV porch light needs to be placed on the outer door of the RV for use, and the light-emitting circuit board 4 is an electronic component, it will malfunction when it comes into contact with water in the operating state. Or damaged, in order to prevent the above situation from occurring, the accommodating groove 10 is surrounded by an installation groove 11 arranged around the accommodating groove 10, a waterproof ring 12 is installed in the installation groove 11, and the shell 1 is provided with an opening for installing the light-emitting device 2 into the shell 1, and a waterproof gasket 22 is installed at the opening to prevent moisture from entering the shell 1. Specifically, the waterproof ring 12 and the waterproof gasket 22 in this embodiment can use rubber and other materials with good sealing and adhesion, wherein the upper surface of the waterproof gasket 22 is surrounded by an upwardly protruding retaining wall 24, and the shell 1 and the light-emitting device 2 are installed inside the retaining wall 24, and in order to enable the waterproof gasket 22 to be stably installed on the shell 1, in this embodiment, waterproof glue is applied to the connection between the waterproof gasket 22 and the shell 1.

[0025] The fixing base 3 includes a mounting plate 13 for mounting the light-emitting circuit board 4. Since the light-emitting circuit board 4 generates heat during the light-emitting process, the light-emitting circuit board 4 will shorten its service life if it works at a high temperature for a long time. In order to extend the service life of the light-emitting circuit board 4, a plurality of heat sinks 14 protruding outwards to improve the heat dissipation effect of the fixing base 3 are provided at the rear end of the mounting plate 13. The heat sink 14 is connected to the base 15. Figure 4 Specifically, in this embodiment, the fixing seat 3 is made of aluminum material with good thermal conductivity, and four heat sinks 14 are provided at the rear end of the fixing seat 3. The third heat sink 14 from top to bottom is fixedly connected to the base 15, and the base 15 and the heat sink 14 are inclined.

[0026] Reference Figure 3: In this example, no additional fixings 21 are required for the installation of the porch light. In order to smoothly install the fixing base 3 into the shell 1, positioning grooves 16 are provided on both sides of the base 15, and a positioning strip 17 is provided on the shell 1 to cooperate with the positioning grooves 16 for positioning. During installation, first make sure that the protective cover 6 installed on the fixing base 3 and the light-emitting groove 19 on the shell 1 are facing the same direction, and then put the fixing base 3 into the opening of the shell 1. Since the base 15 and the heat sink 14 are inclined, it is necessary to first control the protective cover 6 installed on the fixing base 3 to fit into the light-emitting groove 19, and then insert the positioning strip 17 into the positioning groove 16 to position the fixing base 3 and the shell 1. After that, it is only necessary to apply waterproof glue on the connection between the waterproof gasket 22 and the shell 1, and then install the waterproof gasket 22 on the shell 1 to complete the installation.

[0027] After the installation of the porch light is completed, in order to stably install the porch light to the specified position, a plurality of fixing holes 20 are provided on the shell 1, wherein the fixing holes 20 are in a state of penetrating the shell 1, and a plurality of fixing holes 20 are installed with fixing members 21 for fixing the shell 1. Specifically, the fixing members 21 in this embodiment are self-tapping screws, which are easy to install and can also save installation time. When installing the porch light, one side of the shell 1 on which the waterproof gasket 22 is installed is in contact with the outer side of the RV door, and the light-emitting groove 19 is located on the lower side of the shell 1. When in use, since the base 15 and the waterproof gasket 22 are parallel and fit each other, the fixing seat 3 is tilted downward relative to the base 15, so that the light emitted by the light-emitting circuit board 4 is close to one side of the vehicle body to eliminate the lighting blind spot, and can illuminate the area below the porch light. Refer to the attached Figure 3 After the installation is completed, the shell 1 on the side with the fixing hole 20 is located at the lower side and not at the outermost end surface of the shell 1 on this side, so when it rains, most of the rainwater will be blocked by the shell 1 on the other side to prevent the rainwater from entering the inside of the shell 1 through the fixing hole 20.
