Description

[Technical field]

[0001] The present disclosure relates to the technical field of indicator lamps, and more particularly to light-emitting devices. [Background technology]

[0002] Currently, various electrical products are generally provided with indicator lamps. Indicator lamps can not only improve the design of the product, but also provide users with information such as the operating state of the product through light color, flashing, etc. For example, an ambient air quality detection device described in Chinese Patent CN201921131625.6 is provided with an indicator lamp structure as shown in FIG. 1. The indicator lamp structure mainly includes a housing 4, a combination end cap 5, a touch control block 7, and a breathing lamp 8. The combination end cap 5 is provided on the top of the housing 4, the touch control block 7 is provided on the outer surface of the combination end cap 5, and the breathing lamp 8 is provided around the touch control block 7. The breathing lamp 8 includes an annular light-transmitting plate and a plurality of light sources provided below the annular light-transmitting plate. The plurality of light sources emit light rays to irradiate the annular light-transmitting plate above them, thereby providing light-emitting indication. Summary of the Invention

[0003] However, in order to save the material of the annular transparent plate and reduce the cost, the prior art usually provides a gap between the annular transparent plate and the touch-control block 7 at its center, and provides a connection member between the touch-control block 7 and the combined end cap 5 to support the touch-control block 7, and further fixes the touch-control block 7 to the combined end cap 5. However, when the light from the light source is irradiated onto the connection member, the connection member will block a part of the light radiated from below, so that the light path displayed on the annular transparent plate will be intermittent and incomplete, which will cause users to have visual discomfort or mistakenly believe that the product is defective.

[0004] In order to solve the above problems, the present disclosure provides a light emitting device that can prevent the light beam from the light source from being blocked, and further prevent the displayed light path from being intermittent and incomplete.

[0005] In view of the above situation, the objective of the present disclosure is to overcome the shortcomings of the prior art and provide a light-emitting device that, through an ingenious structural design, can prevent the light beam from the light source from being blocked by the connecting member and further ensure the integrity of the optical path.

[0006] The present disclosure is realized by a light emitting device comprising a housing in which a light-transmitting opening is provided, a light source provided inside the housing, and a housing lid that covers the light source and is provided at the light-transmitting opening to cap the housing, wherein the housing lid has an outer periphery lid portion in which an opening is provided, an inner periphery lid portion located within the opening and spaced apart from the outer periphery lid portion to form a light-transmitting gap, and a connecting rib that spans the light-transmitting gap and connects the outer periphery lid portion and the inner periphery lid portion, and the connecting rib is bent toward the inside of the housing to form a light-transmitting recess.

[0007] Compared to conventional technologies, the present disclosure provides a light-emitting device that provides improved aesthetics and usability by designing a connecting rib spanning a light-transmitting gap into a light-transmitting recess that can be bent inside the housing, allowing light from the light source to pass diagonally through the light-transmitting recess and be irradiated into the light-transmitting gap located above the connecting rib, thereby preventing that area from being left unilluminated and resulting in a missing light path, and ensuring that a complete light path is formed in the light-transmitting gap.

[0008] Furthermore, the light-transmitting recess has two recess extension surfaces that extend from both side edges of the light-transmitting gap toward the light source and face each other, and a recess bottom surface that connects the two recess extension surfaces and is close to the light source. The two recess extension surfaces combine with the recess bottom surface to form the light-transmitting recess, so that light from the light source can obliquely irradiate the light-transmitting gap located above the connecting rib, and it is possible to prevent the light path from being missing due to the portion not being irradiated.

[0009] Furthermore, the distance between the recess extension faces is equal to or greater than the width of the light-transmitting gap. If the distance between the two recess extension faces is smaller than the distance of the light-transmitting gap, the light from the light source is unlikely to fill the light-transmitting gap. Therefore, the distance between the two recess extension faces is set to be equal to or greater than the width of the light-transmitting gap to ensure that the light in the light-transmitting gap is saturated, and prevent the user from experiencing visual discomfort or misunderstanding that the product is defective due to the unsaturated optical path.

[0010] Furthermore, the light source is a plurality of lamp beads, and the lamp beads are located below the connecting ribs and offset from the connecting ribs. If the lamp beads are located directly below the connecting ribs, the light from the lamp beads will inevitably be blocked by the connecting ribs and cannot be irradiated into the light-transmitting gaps located above the connecting ribs. Therefore, the present disclosure installs the lamp beads offset from the connecting ribs.

[0011] The housing cover further has a support shaft, which is provided inside the housing, one end of which is fixed to the inner periphery cover portion and the other end of which abuts against the housing in a state where the housing cover caps the housing. The support shaft is for supporting the inner periphery cover portion, and further prevents the housing cover from falling or coming off when it is subjected to pressure from the inner periphery cover portion.

[0012] The housing cover further includes a first reinforcing rib that protrudes from the bottom surface of the inner lid portion toward the light source and connects the connection rib and the support shaft. The first reinforcing rib further reinforces the strength of the inner lid portion and can prevent damage when the inner lid portion is subjected to pressure.

[0013] Furthermore, the housing lid further has a second reinforcing rib that protrudes from the bottom surface of the inner lid portion toward the light source and intersects with the first reinforcing rib. The second reinforcing rib, together with the first reinforcing rib, reinforces the strength of the inner lid portion and prevents damage when the inner lid portion is subjected to pressure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] For better understanding and practice, the present disclosure will now be described in detail with reference to the drawings.

[0016] The light-emitting device disclosed in the present disclosure can be specifically applied to an ion emitter with a light-emitting display function, and can also be applied to an air purifier, an air disinfection device, an in-vehicle air purifier, an air conditioning device, or other devices with a light-emitting display function. In this embodiment, the light-emitting device disclosed in the present disclosure is applied to an ion emitter, and the present disclosure is described by taking the ion emitter with the light-emitting device as a specific embodiment.

[0017] The ion emitter is a portable air treatment device that generates water ions and releases them to the outside of the device, thereby effectively treating the air outside the device with odor removal, sterilization, increased humidity, etc. When the ion emitter is in operation, it displays information about its operating status (e.g., remaining battery power, error reports, etc.) to the user, and is provided with a light-emitting structure that can change functions such as light brightness, light hue, or light flashing frequency in order to improve the aesthetics.

[0018] The light emitting device according to the present disclosure includes a housing 10, a housing cover 20, and a shielding portion 40, as shown in FIGS.

[0019] Specifically, the housing 10 forms a housing for the ion emitter and is columnar in shape, with its cross-sectional area gradually decreasing from top to bottom. The housing 10 is provided with a housing bottom surface 11, a housing side surface 12, a light transmitting opening 13, and a light source mounting portion 14.

[0020] The housing bottom surface 11 is the bottom surface of the columnar housing. The housing bottom surface 11 is generally a flat surface that faces vertically downward and is used for stably placing the ion emitter. The housing bottom surface 11 is further provided with a drain hole (not shown) for discharging unnecessary moisture inside the housing 10.

[0021] The housing side surface 12 is a curved circumferential side surface forming a columnar housing. An air inlet (not shown) is provided on the housing side surface 12 to allow air outside the ion emitter to enter the housing interior. One end of the housing side surface 12 is connected to the housing bottom surface 11 and forms a semi-enclosed structure in combination with the housing bottom surface 11, and the other end of the housing side surface 12 forms an opening, i.e., a light-transmitting opening 13 described below.

[0022] The light transmitting opening 13 is an opening at the top of the side surface 12 of the housing, and serves to transmit light from inside the housing 10 to the outside of the housing 10. The light transmitting opening 13 is located at the top end of the columnar housing, and is an opening that normally faces vertically upward.

[0023] The light source mounting portion 14 is disposed in the internal space of the housing 10 and has a planar structure facing the light transmitting opening 13. A light source 15 is provided on the light source mounting portion 14.

[0024] The light source 15 provides the light emitting function of the ion emitter, and is installed on the light source mounting part 14 and located below the light transmitting opening 13. In this embodiment, the light source emits light vertically upward. That is, the light from the light source 15 passes through the light transmitting opening 13 and is then emitted to the outside of the housing 10. In this embodiment, the light source 15 is three LED light emitting diode lamp beads (hereinafter referred to as lamp beads for short). The three lamp beads are installed horizontally on the light source mounting part 14 and arranged in a ring shape. The light source 15 may be another number of lamp beads or other lighting items.

[0025] The housing cover 20 will be further described with reference to FIGS.

[0026] Please refer to Figures 4 and 5. The housing lid 20 is a lid that detachably caps the light-transmitting opening 13. The housing lid 20 is circular, and completely covers the light-transmitting opening 13 when in a capped state. The housing lid 20 is provided with an outer periphery side lid portion 21, an inner periphery side lid portion 22, a light-transmitting gap 23, a connecting rib 24, a ventilation plate 25, a capping member 26, a button 27, a button connecting rib 28, a support shaft 29, a first reinforcing rib 30, and a second reinforcing rib 31.

[0027] The outer periphery lid portion 21 is provided in the light transmitting opening 13, and serves to block a portion of the light beam from the light source. The outer periphery lid portion 21 is preferably annular. The outer periphery lid portion 21 is provided with screw holes (two in this embodiment) for inserting screws to fix the housing lid 20 to the housing 10. Here, the surface of the outer periphery lid portion 21 facing the light source is defined as the bottom surface of the outer periphery lid portion 21.

[0028] The inner lid portion 22 is provided in the light-transmitting opening 13, is located inside the area surrounded by the outer lid portion 21, and is located at the center of the housing lid 20 to block part of the light from the light source. The inner lid portion 22 has a partially missing circular shape. The inner lid portion 22 is on the same plane as the outer lid portion 21. Here, the surface of the inner lid portion 22 facing the light source is defined as the bottom surface of the inner lid portion 22.

[0029] The light-transmitting gap 23 is formed by leaving a gap between the outer periphery-side cover portion 21 and the inner periphery-side cover portion 22. The light-transmitting gap 23 is substantially annular, and is intended to allow light from the light source 15 to pass therethrough and disperse to the outside of the housing 10.

[0030] Please refer to FIG. 5 and FIG. 6. The connection rib 24 is a connection structure for connecting the connection inner periphery side cover part 22 and the outer periphery side cover part 21 across the light-transmitting gap 23, and is also a structure for supporting the inner periphery side cover part 22. In this embodiment, two connection ribs 24 are provided. Specifically, the connection rib 24 is provided below the inner periphery side cover part 22 and the outer periphery side cover part 21, one end is connected to the bottom surface of the inner periphery side cover part 22, and the other end is connected to the bottom surface of the outer periphery side cover part 21. From the viewpoint of avoiding blocking of light rays from below, the connection rib 24 is preferably installed so that the projection on the light-transmitting gap 23 is as small as possible. The connection rib 24 is not installed directly above the light source 15, that is, it is installed offset from the light source 15. The connection rib 24 is provided with a light-transmitting recess. Furthermore, the light-transmitting recess will be described with reference to FIG. 7. The light-transmitting recess is a recessed hollow space formed by bending the connection rib 24 toward the inside of the housing. The light-transmitting recess has a recess extension surface 241 and a recess bottom surface 242 .

[0031] The recess extension surface 241 is a surface that extends downward from both sides of the light-transmitting gap 23, that is, from the outer edge of the inner periphery-side lid portion 22 and the inner edge of the outer periphery-side lid portion 21. Two recess extension surfaces 241 are provided in each light-transmitting recess. The two recess extension surfaces 241 are disposed opposite each other. The distance between the two recess extension surfaces 241 is set to be equal to or greater than the width of the light-transmitting gap 23. Note that "equal" does not necessarily mean completely equal, and considering factors such as the manufacturing technology of the product, there may be a slight increase or decrease within the error tolerance range. In addition, the longer the length of the recess extension surface 241 in the vertical direction, the more preferable it is. The recess extension surface 241 may be an arc surface or a surface that combines multiple flat surfaces or arc surfaces. In addition, the recess extension surface 241 may be provided extending from the bottom surface of the inner periphery-side lid portion 22 and the bottom surface of the outer periphery-side lid portion 21.

[0032] The recess bottom surface 242 is a plane where the ends of the two recess extension surfaces 241 closer to the light source 15 are connected to each other. The area of ​​the recess bottom surface 242 is preferably equal to or greater than the width of the light-transmitting gap 23. The recess bottom surface 242 may be an arc surface or a surface combining a plurality of planes or arc surfaces. The recess bottom surface 242, together with the two recess extension surfaces 241, forms a light-transmitting recess.

[0033] Returning to Figures 4, 5 and 6, the other members of the housing lid 20 will be described below. The ventilation plate 25 is provided so as to surround the outer periphery side lid portion 21 and is located on the outermost side of the housing lid 20. The ventilation plate 25 is provided with a plurality of air exhaust ports. The air exhaust ports are strip-shaped and arranged to form a grid ring structure, and are intended to exhaust the air inside the housing 10 to the outside of the housing 10 after mixing with ions.

[0034] The capping member 26 is a part located on the outermost side of the housing lid 20, and serves to cap the housing lid 20 and fix the housing lid 20 to the housing 10. In this embodiment, the capping member 26 has a hook-shaped engagement structure. The capping member 26 may also have a structure capable of realizing a fixing function, such as a spiral pattern.

[0035] The button 27 is located between the outer periphery lid portion 21 and the inner periphery lid portion 22, and is used for realizing a control function for the ion emitter by the user pressing the button. The control function includes starting and stopping the device. In this embodiment, the button 27 is combined with a touch-type key switch below it to form a switch function for the ion emitter. That is, when pressure is applied in the switch operation direction (vertically downward) under conditions that satisfy the operating force, the switch function is turned on, and when the pressure is released, the switch is turned off.

[0036] The button connection rib 28 is for connecting the button to the inner periphery lid portion 22 and / or the outer periphery lid portion 21 to fix the button to the inner periphery lid portion 22. Furthermore, the tough deformation of the button connection rib 28 allows the button to change position and return to its original position when pressed. Therefore, it is preferable that the material of the button connection rib 28 has toughness. In the embodiment of the present disclosure, two button connection ribs 28 are provided. One end of one of the button connection ribs 28 is connected to the edge of the inner periphery lid portion 22, and the other end is connected to the button 27. One end of the other button connection rib 28 is connected to the edge of the outer periphery lid portion 21, and the other end is connected to the button 27.

[0037] The support shaft 29 is for supporting the inner lid portion 22, and has a columnar structure extending from the bottom surface of the inner lid portion 22 toward the light source 15. That is, one end of the support shaft 29 is provided on the bottom surface of the inner lid portion 22, and the other end comes into contact with the light source mounting portion 14 when the housing lid 20 is in the capping state, and the two abut against each other to perform a supporting function. Preferably, the support shaft 29 is provided at the center position of the inner lid portion 22.

[0038] Please refer to Figures 6 and 7. The first reinforcing rib 30 is a rib that protrudes from the bottom surface of the inner periphery side cover portion 22 toward the light source 15, and both ends thereof are connected to the support shaft 29 and the connecting rib 24, respectively. In this embodiment, the number of first reinforcing ribs 30 is two. Preferably, the first reinforcing ribs 30 have a shape that gradually expands downward as it approaches the support shaft 29. In other words, the vertical extension length of the end of the first reinforcing rib 30 close to the support shaft 29 is greater than the vertical extension length of the end of the first reinforcing rib 30 close to the connecting rib 24. In the embodiment of the present disclosure, the first reinforcing rib 30 and the connecting rib 24 are provided by integral molding.

[0039] The second reinforcing rib 31 is a rib that protrudes from the bottom surface of the inner periphery side lid portion 22 toward the light source, and both ends thereof are connected to the first reinforcing rib 30 and the edge portion of the inner periphery side lid portion 22, respectively.

[0040] The shielding portion 40 will be further described with reference to FIG. 9 and FIG.

[0041] The shielding part 40 is located above the housing cover 20 and is intended to shield a part of the housing cover 20, preventing the user from directly viewing the internal components such as the outer periphery cover part 21, the inner periphery cover part 22, and the button 27, thereby improving the aesthetics of the product. The shielding part 40 is also intended to indicate the formation of an optical path. In this embodiment, the shielding part 40 is a circular sticker, the diameter of which is equal to the outer diameter of the outer periphery cover part 21. That is, the shielding part 40 completely covers the outer periphery cover part 21 and all the components surrounded by the outer periphery cover part 21. The shielding part 40 may be a plate-shaped structural part or the like capable of realizing a shielding function. Usually, the shielding part 40 is printed with a pattern such as a device part number, a brand mark, a decorative figure, etc., corresponding to the button position. The shielding part 40 is provided with a light-transmitting bar 41.

[0042] The light-transmitting bar 41 is disposed at a position in the shielding portion 40 corresponding to the light-transmitting gap 23 of the housing cover 20, and is made of a light-transmitting material. The light-transmitting bar 41 is provided in an annular shape, and causes the transmitted light rays to form an annular light path indication. In a plan view perpendicular to the housing cover 20, the light source is located inside the portion surrounded by the annular light-transmitting bar 41. In the embodiment of the present disclosure, the light-transmitting bar 41 is made of a light-transmitting material and is provided integrally with the sticker. The light-transmitting bar 41 may be a gap.

[0043] The above is a description of the structure of the light emitting device according to the embodiment of the present disclosure. Hereinafter, the principle of optical path formation of the light emitting device according to the embodiment of the present disclosure will be described with reference to Figs.

[0044] The light source 15 (i.e., three lamp beads) located inside the housing 10 emits light when the power is turned on. The light diverges from the light source 15 to the surroundings and irradiates the housing cover 20. At this time, the outer periphery cover part 21 and the inner periphery cover part 22 of the housing cover 20 block the light, so the light cannot pass through. At the same time, a light-transmitting gap 23 is provided between the outer periphery cover part 21 and the inner periphery cover part 22, so the light can pass through the light-transmitting gap 23. In addition, a button 27 and a button connection rib 28 are further provided between the outer periphery cover part 21 and the inner periphery cover part 22, so the light also passes through the gap between them. In the above situation, the shielding part 40 (i.e., a sticker) is provided above the housing cover 20 in order to form a completely annular light path on the housing cover 20. Specifically, the shielding part 40 is provided with a light-transmitting bar 41 having a light-transmitting effect at a position corresponding to the light-transmitting gap 23 according to the shape of the light-transmitting gap 23. The rest of the shielding part 40 other than the translucent bar 41 is made of an opaque material. Therefore, the light passing through the vicinity of the button 27 and the button connecting rib 28 is blocked by the opaque material of the shielding part 40 and cannot be emitted outside the ion emitter. In other words, the only light that can be emitted outside the light emitting device is the light that passes through the translucent bar 41 of the shielding part 40. The light finally forms a ring-shaped light path mark on the shielding part 40.

[0045] Next, the operation and effect of the related structure of the light emitting device according to the embodiment of the present disclosure will be described with reference to FIG.

[0046] The light-transmitting recess of the connection rib 24 is a hollow space formed by bending downward at the light-transmitting gap 23. Therefore, the light from the light source 15 can pass obliquely through the hollow space of the recess and be irradiated to the transparent material (light path shown by C) of the shielding part 40 above the light-transmitting recess. Therefore, it is possible to prevent the upper part of the connection rib 24 from being blocked by the light, and to prevent a dark part (i.e., a missing light path) from appearing in the annular light path, thereby preventing the user from having visual discomfort or misunderstanding that the product is defective. At the same time, the connection rib 24 connects the outer periphery side cover part 21 and the inner periphery side cover part 22, and prevents the inner periphery side cover part 22 from coming off due to lack of any support, thereby realizing the integration of the outer periphery side cover part 21 and the inner periphery side cover part 22, and the user can easily remove and install the housing cover 20.

[0047] The distance between the two recess extension surfaces 241 is set to be greater than or equal to the width of the light-transmitting gap 23, thereby expanding the range over which light rays are irradiated onto the light-transmitting gap 23, i.e., reducing the blocking of the light rays that can be irradiated onto the light-transmitting gap 23 by the recess extension surfaces 241.

[0048] The lamp beads as the light source 15 are installed offset from the connecting rib 24. That is, the lamp beads are not installed vertically directly below the connecting rib 24, so that more light can pass through the light-transmitting recess of the connecting rib 24 obliquely and be irradiated to the transparent material of the shielding part 40 above the light-transmitting recess. If the lamp beads are installed vertically directly below the connecting rib 24, the connecting rib 24 located directly above the lamp beads will block the light from directly below. The light from the lamp beads located at other positions can pass through the light-transmitting recess of the connecting rib 24 obliquely, but the light irradiated above the connecting rib 24 may be insufficient, so that the light path above the connecting rib 24 may become dark and the light path may be missing. Therefore, the lamp beads are installed offset from the connecting rib 24, so that the light irradiated above the connecting rib can be guaranteed to be sufficient, and the user is prevented from having visual discomfort or misunderstanding that the product is defective.

[0049] The support shaft 29 is intended to improve the pressure resistance of the inner lid portion 22. Since the inner lid portion 22 is provided with a button that the user presses, a downward force is generated in the inner lid portion 22 connected to the button every time the user presses the button. Therefore, by abutting the support shaft 29 with the light source mounting portion 14, the pressure received by the inner lid portion 22 can be dispersed to the light source mounting portion 14, preventing damage to the inner lid portion 22 or the connecting rib 24 when a large force is applied thereto.

[0050] Similarly, the first reinforcing rib 30 and the second reinforcing rib 31 are also intended to improve the pressure resistance of the inner lid portion 22. That is, the thickness of the inner lid portion 22 is locally increased to improve the pressure resistance. The vertical length of the connection portion between the first reinforcing rib 30 and the support shaft 29 is set to be greater than the vertical length of the connection portion between the first reinforcing rib 30 and the connecting rib 24. That is, the contact area between the first reinforcing rib 30 and the support shaft 29 increases, and when the inner lid portion 22 receives a force, the pressure can be more fully dispersed to the support shaft 29 and then transmitted to the light source mounting portion 14 before being dispersed.

[0051] The above examples merely show some embodiments of the present disclosure. Although the description is specific and detailed, it should not be understood that this limits the scope of the claims of the present disclosure. In addition, those skilled in the art can make various modifications and improvements within the scope of the idea of ​​the present disclosure, and these also belong to the scope of protection of the present disclosure.
