Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a ground lamp. Background Art

[0002] Chinese utility model patent publication number CN209484481U discloses a ground lamp built into an exterior rearview mirror. To improve heat dissipation, heat dissipation holes are added to the heat-concentrating area of ​​the lamp housing, and cooling fins are added to the back of the circuit board. While this patent incorporates these heat dissipation measures, the added heat dissipation holes in the lamp housing do not guarantee the lamp's overall dust and water resistance.

[0003] The Chinese utility model patent with publication number CN205909138U discloses a ground lamp externally mounted on the left and right rearview mirrors. In order to improve the sealing performance, a waterproof sealing strip is added between the lamp housing and the lampshade. Although the patent has taken corresponding waterproof measures, the lamp housing is made of plastic and there is no heat sink added on the back. The entire lamp uses a low-power LED (Light Emitting Diode) to reduce heat output, which results in an unsatisfactory lighting effect. Although the sealing structure has been added to solve the sealing problem, the lack of air holes and ventilation structure causes condensation in the lamp under high and low temperature working conditions.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0028] A ground lamp, such as Figures 1 to 5 Shown, including,

[0029] The mask 1 and the lamp housing 2 connected to the mask 1 form an accommodating space, in which a lighting structure 3 is arranged. The lamp housing 2 is provided with an air vent 4 communicating with the accommodating space, and the air vent 4 is covered with a breathable membrane 5.

[0030] Specifically, the present invention provides a ground lamp that is externally mounted on the vehicle chassis for auxiliary lighting. The lighting structure 3 is housed within a housing, ensuring a dust- and water-resistant seal. The air vents 4 and the breathable membrane 5 attached thereto prevent condensation within the lamp even under high and low temperature operating conditions.

[0031] Reference Figure 2 The mask 1 is symmetrical along the central axis of the floor lamp and is a two-color injection molded mask. The two-color injection molding process reduces the painting step during the production process, thereby reducing manufacturing costs and production time. Furthermore, the two-color design can be completed in a single molding process, eliminating the need for subsequent secondary processing.

[0032] In a preferred embodiment, the lighting structure 3 includes:

[0033] Circuit board 31, connected to lamp housing 2;

[0034] The light source 32 is provided on a side of the circuit board 31 away from the lamp housing 2;

[0035] An optical lens 6 for focusing light from the light source 32 is also provided in the accommodating space. The optical lens 6 is located on the light-emitting side of the light source 32 .

[0036] Specifically, the optical lens 6 is located on the light-emitting side of the light source 32, which can effectively focus the light emitted by the light source 32, thereby improving the brightness and light efficiency of the lighting. The design of the lens can concentrate the scattered light on a specific area, improving the lighting effect.

[0037] The circuit board 31 with good heat dissipation can extend the service life of the LED light source 32 and ensure its stable operation.

[0038] The overall structure is compact, which helps to optimize the use of internal space.

[0039] In a preferred embodiment, heat-conducting glue is provided between the lighting structure 3 and the lamp housing 2 .

[0040] Specifically, a layer of thermally conductive adhesive is placed between the circuit board 31 in the lighting structure 3 and the lamp housing 2 , which are in a bonded state to improve heat dissipation performance.

[0041] In a preferred embodiment, a sealing ring 7 is provided between the lamp housing 2 and the mask 1 .

[0042] Specifically, there is a sealing ring 7 between the mask 1 and the lamp housing 2, which can meet the sealing requirements of IP65 dust and water resistance level.

[0043] In a preferred embodiment, the lamp housing 2 is provided with a connector 8 close to the vent hole 4;

[0044] The lamp housing 2 is provided with a buckle fixedly connected to the mask 1 .

[0045] Specifically, the provision of the connector 8 helps to improve the overall structural stability of the lamp housing 2, can effectively fix the lamp housing 2, and prevent the lamp housing 2 from loosening or shifting due to vibration or impact during use, thereby improving the durability of the lamp.

[0046] The buckle connection design with the mask 1 ensures that the mask 1 remains tightly fixed during use, preventing it from loosening or falling off due to external forces. At the same time, the buckle design makes the mask 1 easier to assemble and disassemble, making it convenient to clean or replace.

[0047] In a preferred embodiment, the lamp housing 2 is further provided with heat dissipation fins 9 , which are inserted between the air vents 4 and the connector 8 .

[0048] Specifically, the lamp housing 2 is a metal housing with good thermal conductivity, which meets the heat dissipation requirements of high-power LEDs. There are heat dissipation fins 9 on the back of the housing to further improve the heat dissipation performance.

[0049] In a preferred embodiment, the front end of the lamp housing 2 is provided with a first mounting hole 10 for connecting to the vehicle body;

[0050] Second mounting holes 11 for connecting to the vehicle body are provided on both sides of the mask 1 .

[0051] Specifically, the design of the first mounting hole 10 and the second mounting hole 11 provides multiple connection points, which helps to maintain the stability of the lamp during the installation process and prevent the lamp from loosening or falling off due to vibration or impact during use.

[0052] By designing mounting holes on the front and sides, we can avoid excessive installation marks on the vehicle body, keeping the vehicle body clean and beautiful, and improving the overall visual effect. It can also reduce the amount of moisture or dirt entering the lamp through the mounting holes, improving the lamp's waterproof performance and ensuring its normal operation in harsh environments.

[0053] Specifically, when designing the floor lamp for this utility model, the first step is to determine the black box dimensions and the matching method with the handpiece. Then, the mask 1 and lamp housing 2 are designed based on the black box dimensions. The size of the circuit board 31 is designed based on the lamp housing 2. The position of the LED and the lens are determined based on the mask 1. The sealing ring 7 is then designed, and finally the position of the air vent 4 is designed. The shape of the floor lamp can be adjusted according to the actual space and shape, but the sealing method, heat dissipation method, and anti-condensation method must remain consistent with this application.

[0054] The floor lamp of the present invention is connected to the lamp housing 2 through the mask 1 to meet the sealing requirements of IP65 dust and water resistance level. A breathable membrane 5 is attached to the air vent 4 to prevent condensation. Heat dissipation fins 9 are provided on the back of the lamp housing 2 for efficient heat dissipation.

[0055] In summary, this application provides a floor lamp that, by adding a vent hole 4 behind the lamp housing 2 and attaching a breathable membrane 5 to the vent hole 4, can meet the requirement of preventing condensation in the lamp under high and low temperature operating conditions. Furthermore, the circuit board 31 and light source 32 are housed within the housing formed by the mask 1 and the lamp housing 2. Heat dissipation fins 9 are employed on the back of the lamp housing 2 to meet the requirements of sealing and heat dissipation.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
