This ensures that the air pressure inside the lamp is the same as the air pressure outside the lamp, so that the pressure sensor can detect the air pressure value at the location of the lamp. This solves the technical problem in the prior art that the detected air pressure inside the lamp differs greatly from the actual air pressure value outside the lamp. Attached Figure Description

Detailed Implementation

[0032] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Currently, lighting fixtures have been equipped with various functions to meet the functional needs of different user groups, such as altitude detection. Calculating altitude by detecting air pressure is a relatively accurate method. However, the poor airflow inside current lighting fixtures causes a significant difference between the air pressure value detected by the internal air pressure sensor and the external air pressure value, affecting the accuracy of the detection.

[0036] like Figure 1-8 As shown, in one embodiment of a lighting fixture, the fixture includes a housing assembly 10, a light-emitting component 20, a control assembly 90, a waterproof and breathable membrane 30, and a pressure sensor. The housing assembly 10 has a light-transmitting portion 15, an installation space 16 within it, and a vent 134 communicating with the installation space 16. The light-emitting component 20 is housed within the installation space 16, and the light-emitting component 20 and the light-transmitting portion 15 are arranged sequentially along a light path. The control assembly 90 is housed within the installation space 16 and electrically connected to the light-emitting component 20 to drive it to emit light. The waterproof and breathable membrane 30 is installed on the housing assembly 10 and covers the vent 134, allowing outside air to sequentially pass through the waterproof and breathable membrane 30 and the vent 134 into the installation space 16. The pressure sensor is housed within the installation space 16 and is used to detect the air pressure within the installation space 16.

[0037] In this embodiment, the waterproof and breathable membrane 30 prevents liquid from entering the lamp through the vent 134, but outside air can still enter the installation space 16 through the waterproof and breathable membrane 30 and the vent 134 in sequence. This ensures that the air pressure inside the lamp is the same as the air pressure outside the lamp, so that the air pressure sensor can detect the air pressure value at the location of the lamp. This solves the technical problem in the prior art that the detected air pressure inside the lamp differs greatly from the actual air pressure value outside the lamp.

[0038] In one embodiment of the lighting fixture, combined with Figure 1-3 and Figure 6-8 As shown, the lamp also includes a vent ring 40, which is fitted onto the housing assembly 10. A gap 100 is left between the vent ring 40 and the housing assembly 10, and the gap 100 is connected to the vent hole 134 through the waterproof and breathable membrane 30. The vent ring 40 is provided with a connecting hole 41, through which the gap 100 is connected to the outside.

[0039] In this embodiment, specifically, the inner ring size of the vent ring 40 is larger than the outer ring size at the corresponding vent hole 134 position of the housing assembly 10, so that a gap 100 can be formed between the vent ring 40 and the housing assembly 10. The gap 100 can be connected to the outside through the connecting hole 41, so that the gap 100 forms an open space connected to the outside.

[0040] Furthermore, it is understood that in order for the vent 134 to connect with the outside air and the installation space 16, the vent 134 needs to penetrate the housing assembly 10 and communicate with the outside. The waterproof and breathable membrane 30 is disposed on the outer surface of the housing assembly 10, thereby preventing liquid residue from remaining inside the vent 134. In this embodiment, the breathable ring 40 can cover the waterproof and breathable membrane 30, preventing the user from touching or rubbing against it, thus preventing the user from damaging the waterproof and breathable performance of the membrane 30.

[0041] In one embodiment of the lighting fixture, the housing assembly 10 includes an annular shell 12, a first outer shell 11, an annular connecting shell 13, and a second outer shell 14. One end of the annular shell 12 is connected to the annular connecting shell 13, and the light-emitting component 20 is connected to the other end of the annular shell 12. A vent 134 is provided in the annular connecting shell 13, and a vent ring 40 is sleeved on the annular connecting shell 13. The first outer shell 11 is sleeved on the annular shell 12 and is sealed to the annular connecting shell 13. A light-transmitting portion 15 is provided in the first outer shell 11. The second outer shell 14 is sealed to the annular connecting shell 13. The second outer shell 14, the annular connecting shell 13, and the first outer shell 11 form an installation space 16. The annular shell 12 is housed in the installation space 16, and the control component 90 is housed in the inner annular space of the annular shell 12.

[0042] In this embodiment, preferably, the light-transmitting part 15 is located at one end of the first outer shell. The light-transmitting part 15 can be a plate-like structure made of a transparent material, such as transparent glass, and can be installed on the first outer shell 11 by embedding, so that the first outer shell 11 and the light-transmitting part 15 together form a cylindrical structure, which can then cover the annular shell 12. Alternatively, the light-transmitting part 15 can also be integrally formed with the first outer shell 11 to form a cylindrical structure, with the bottom of the cylinder being a light-transmitting structure.

[0043] The first outer shell 11 and the second outer shell 14 can be connected to the annular connecting shell 13 by means of threads or snaps. A sealing ring is used to achieve a seal between the first outer shell 11 and the second outer shell 14 and the annular connecting shell 13. It should be noted that the sealing ring is fitted onto the outer shell with the smaller outer ring size. In one specific embodiment of the annular connecting shell 13, the outer ring size of the annular connecting shell 13 is smaller than that of the first outer shell 11 and larger than that of the second outer shell 14. Correspondingly, a first sealing ring 60 is fitted onto the connecting shell to seal with the first outer shell 11, and a second sealing ring 70 is fitted onto the second outer shell 14 to seal with the annular connecting shell 13. Thus, the first sealing ring 60 and the second sealing ring 70 seal the gap between the first outer shell 11 and the second outer shell 14 and the annular connecting shell 13, forming a sealed installation space 16 that allows gas to enter and exit only through the vent hole 134. It is understood that the first outer shell 11, the annular connecting shell 13 and the second outer shell 14 can form the installation space 16, and the annular shell 12 can be housed in the installation space 16, and the control component 90 can be housed in the inner ring space of the annular shell 12.

[0044] In one embodiment of the lighting fixture, combined with Figure 3-8 As shown, the control assembly 90 includes a control board 91 and a partition 92. One end of the control board 91 is connected to the light-emitting component 20, and the other end is connected to the partition 92. A pressure sensor is mounted on the control board 91. The partition 92 divides the installation space 16 into a first space 161 and a second space 162. The control board 91 is located in the first space 161, and the vent 134 communicates with the second space 162. The annular shell 12 is provided with a clearance groove 123 at a position relative to the control assembly 90. The clearance groove 123 forms a gap with the control assembly 90 to allow the first space 161 to communicate with the second space 162. This allows outside air entering the second space 162 through the vent 134 to be introduced into the first space 161.

[0045] In this embodiment, it is understood that electrodes are mounted on the partition 92, and a battery 50 housed in the mounting space 16 is provided between the partition 92 and the second housing 14. Electrodes are provided on the bottom of the second housing 14, thereby forming a closed circuit with the partition 92 and the battery 50, so that the battery 50 can provide power to the control board 91. In addition, a button 141 can be provided on the second housing 14. Pressing the button 141 can make the electrodes on the second housing 14 contact the battery 50, thereby connecting the circuit; pressing the button 141 again can separate the electrodes on the second housing 14 from the battery 50, thereby turning the control board 91 on and off, and thus turning the light-emitting component 20 on and off.

[0046] Specifically, the partition 92 can be a circular plate structure, and the annular shell 12 can be a solid annular shell structure. A connecting platform for supporting and mounting the partition 92 is provided on the inner wall of the annular shell 12. The connecting platform can be composed of two arc-shaped plates. The partition 92 is placed on the connecting platform, and the diameter of the partition 92 can match the inner ring diameter of the annular shell 12 to prevent the partition 92 from shaking. In this embodiment, the clearance groove 123 is located between the two arc-shaped plates and extends along the axial direction of the annular shell 12. The extension length of the clearance groove 123 must be at least greater than the thickness of the partition 92. That is, there is a gap between the bottom of the clearance groove 123 and the side wall of the partition 92, allowing the first space 161 and the second space 162 on opposite sides of the partition 92 to communicate. This allows outside air to sequentially pass through the connecting hole 41, the waterproof and breathable membrane 30, the vent 134, and the second space 162 into the first space 161, where it is detected by the air pressure sensor on the control board 91.

[0047] By setting the anti-air groove 123, the air pressure on both sides of the partition 92 can be kept consistent, avoiding the deviation between the air pressure value detected by the air pressure sensor and the actual air pressure value outside the lamp, thus improving the accuracy of the overall lamp in detecting external air pressure.

[0048] In one embodiment of the lighting fixture, combined with Figure 1-6 As shown, the annular connecting shell 13 has a boss 132. The first outer shell 11 abuts against one side of the boss 132 at one end, and one end of the vent ring 40 abuts against the other side of the boss 132. The second outer shell 14 abuts against the other end of the vent ring 40.

[0049] As mentioned in the previous embodiments, the first outer shell 11 can be a cylindrical structure similar to a test tube. In this embodiment, it is understood that when the second outer shell 14 is connected to the annular connecting shell 13 by means of snap-fit ​​or threaded connection, it can press against one end of the vent ring 40, causing the other end of the vent ring 40 to abut against the boss 132, thereby pressing the vent ring 40 between the boss 132 and the second outer shell 14. Preferably, the outer ring size of the first outer shell 11 matches the outer perimeter size of the boss 132, improving the overall consistency of the lamp.

[0050] In one embodiment of the lighting fixture, combined with Figure 1-3 As shown, there are multiple connecting holes 41, which are evenly distributed around the vent ring 40 along its circumference. Each connecting hole 41 passes through one end of the vent ring 40 opposite the boss 132. The boss 132 has a protrusion 133 on the side opposite the vent ring 40. The protrusion 133 can partially fill one of the connecting holes 41 to restrict the rotation of the vent ring 40 relative to the annular connecting shell 13.

[0051] In this embodiment, specifically, the vent ring 40 has a circular structure. By providing multiple connecting holes 41, the connection between the gap 100 and the outside air can be increased, thereby facilitating the flow of outside air into the gap 100 and preventing all the connecting holes 41 from being closed when held by a person. Furthermore, the partial filling by the protrusions 133 can restrict the rotation of the vent ring 40, prevent the vent ring 40 from rotating on the annular connecting shell 13, and ensure that the connecting holes 41 can still connect the gap 100 and the outside space.

[0052] Preferably, multiple support blocks can be provided on the surface of the annular connecting shell 13 below the boss 132 along the circumference of the annular connecting shell 13. The multiple support blocks are arranged in a ring shape, and the interval between adjacent support blocks is the same. The outer ring diameter of the ring formed by the support blocks matches the inner ring diameter of the breathable ring 40, so that the breathable ring 40 can be supported by the support blocks, maintaining the gap 100 and preventing the breathable ring 40 from squeezing and rubbing against the waterproof breathable membrane 30.

[0053] More preferably, the support block and the protrusion 133 can be integrally formed to form a T-shaped block.

[0054] In addition, there can be multiple protrusions 133. The number of protrusions 133 can correspond one-to-one with the number of connecting holes 41, or be half the number of connecting holes 41. That is, there is a connecting hole 41 and two posts forming a connecting hole 41 between adjacent protrusions 133.

[0055] In one embodiment of the lamp, one end of the annular shell 12 is provided with a connecting post 121, which passes through the light-emitting component 20. The other end of the annular shell 12 is provided with a protrusion 122. The annular connecting shell 13 is provided with a notch 131 that matches the protrusion 122 at one end of the annular shell 12, so that the relative rotation of the annular shell 12 and the annular connecting shell 13 can be restricted by the protrusion 122 and the notch 131.

[0056] In this embodiment, specifically, multiple connecting posts 121 are provided along the circumference of the annular shell 12. The connecting posts 121 are rivets. During assembly, after the rivets pass through the light-emitting plate, they are welded to be flush with the surface of the light-emitting plate away from the annular shell 12, thereby fixing the light-emitting plate to the annular shell 12. In addition, through the cooperation of the protrusion 122 and the notch 131, the annular shell 12 and the annular connecting shell 13 can be quickly connected and installed, improving assembly efficiency while preventing relative rotation between the annular shell 12 and the annular connecting shell 13.

[0057] The cooperation between the protrusion 122 and the notch 131, as well as the cooperation between the protrusion 133 and the connecting hole 41, can improve the overall assembly efficiency of the lamp.

[0058] In one embodiment of the lamp, the lamp further includes an indicator component 80, which is mounted on the light-emitting component 20 and is communicatively connected to the pressure sensor to display the pressure value detected by the pressure sensor.

[0059] In this embodiment, specifically, the light-emitting component 20 includes a light-emitting plate and light-emitting LEDs, with the light-emitting plate used to mount the light-emitting LEDs. The light-emitting LEDs can come in various forms and types, meaning that multiple light-emitting LEDs can be set, such as red LEDs, blue LEDs, infrared lasers, and white light-emitting diodes, thereby emitting different types of light for easy use in different scenarios.

[0060] The indicator component 80 can be a display screen that can display different numbers by combining multiple LEDs to make it easy for users to know the outside air pressure value.

[0061] The light-emitting plate is a circular plate structure, arranged parallel to the partition 92, and the control board 91 is located between the light-emitting plate and the partition 92. The two ends of the control board 91 are fixedly connected to the light-emitting plate and the partition 92 respectively, thus forming a light source circuit board assembly, which is then assembled as a whole, improving assembly efficiency and stability.

[0062] In one embodiment of the lighting fixture, the fixture further includes an indicator component 80, which is mounted on the light-emitting component 20 and is communicatively connected to a barometric pressure sensor via a control component 90. The control component 90 can convert the barometric pressure value detected by the barometric pressure sensor into altitude information for display by the indicator component 80. The indicator component 80 includes multiple indicator lights, each with a different indicator color to display different altitude information.

[0063] In this embodiment, the indication of the indicator component 80 can also take another form. For example, the indicator component 80 may include three indicator lights, namely the first indicator light 81, the second indicator light 82 and the third indicator light 83. By setting the colors of the three indicator lights to different colors, such as red, green and yellow, they can be used to indicate the altitude, making it easier for users to observe and remind them.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
