Description

TECHNICAL FIELD

[0001] Embodiments of the present specification relate to the technical field of lighting devices, and in particular to a light guide column and a lamp. BACKGROUND

[0002] The light emitting characteristics of LEDs are unique, as they can be regarded as point light sources due to their small light emitting area, and have excellent light emitting consistency and a small solid angle. This means that the light emitted by a single LED light emitting unit forms a small light beam in space, and the light emitting angle is relatively small and the light is relatively concentrated.

[0003] In order to obtain a greater lighting effect, the light emitting angle and light distribution of the LED light emitting unit can be adjusted by adding optical devices such as a reflector cup or a lens. However, due to the directional limitations of the reflector cup and the lens, it is not possible to achieve a large angle or even 360° full angle light emission. The LED bulb can also be refracted by a milky white lampshade to expand the illumination angle and thus expand the lighting area. However, a large area of milky white lampshade affects the user's visual experience. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the embodiments will be described in detail below with reference to the drawings. Obviously, the following description is some examples or embodiments of the present specification, and those skilled in the art can also apply the technical solutions or means disclosed in the present specification to other scenarios without creative labor.

However, the terms can be replaced with other expressions if other expressions can achieve the same purpose.

Generally, the terms "include", "comprise" and the like indicate only the inclusion of the steps, elements or components explicitly identified by the description, and these steps, elements and components do not constitute an exclusive list of the methods or devices described.

[0034] In the description of the present specification, it should be understood that the technical terms described in the present specification of components, elements, etc. are not limited to singular, but can also include plural. Generally, the terms "include", "comprise" and the like indicate only the inclusion of the steps, elements or components explicitly identified by the description, and these steps, elements and components do not constitute an exclusive list of the methods or devices described.

[0035] An LED (Light Emitting Diode) is a semiconductor device that can convert electrical energy into light energy. In some embodiments, an LED can include an n-type semiconductor and a p-type semiconductor, which form a p-n junction when the two semiconductor materials are in contact. When a positive voltage is applied, electrons from the n-type region enter the p-type region and combine with holes to release energy. In some embodiments, the energy can be released in the form of photons, resulting in a light emitting phenomenon.

[0036] LED light source devices with LED light emitting units gradually replace traditional bulb (such as tungsten filament lamp, incandescent lamp) due to high luminous brightness, uniform light emission, and low power consumption. With the further development of lighting technology, LED light source devices gradually form various types of bulb light sources. However, the light emitting characteristics of LEDs are unique, as they can be considered as point light sources due to their small light emitting area, with excellent light emitting consistency and small solid angle. This means that the light emitted by a single LED light emitting unit forms a small light beam in space, with a relatively small light emitting angle and concentrated light.

[0037] In some related embodiments, in order to obtain greater lighting effect, the light-emitting angle and light distribution of the LED light-emitting unit can be adjusted by adding optical devices such as reflector cups or lenses. However, due to the directional limitation of the reflector cup and the lens, it is impossible to achieve large-angle or even 360° full-angle light emission. In other related embodiments, the LED bulb can also be refracted by a milky white lampshade to expand the illumination angle and thus expand the lighting area. However, the large-area milky white lampshade affects the user's visual experience.

[0038] Based on this, one or more embodiments of the present specification provide a light guide column which can achieve large-angle or even 360° full-angle light emission, while providing a transparent lighting area and good visual experience.

Referring to Figures 1 to 4 In some embodiments, the columnar structure 1 can refer to a structure that extends along an axis direction and has a specific collective shape. In some embodiments, the columnar structure 1 can be formed by two parallel planes and a curved surface. In some embodiments, the columnar structure 1 has two equal bottom surfaces, and the shape of the bottom surface can be circular, elliptical or polygonal, or other irregular closed figures. In some embodiments, all cross sections of the columnar structure 1 can be similar or identical to the bottom surface. In some embodiments, the side surface of the columnar structure 1 can include a plurality of parallelograms, for example, a plurality of rectangles. In some embodiments, the columnar structure 1 can be a straight column, for example, the side surface of the columnar structure 1 is perpendicular to the bottom surface. In other embodiments, the columnar structure 1 can also be an inclined column, for example, the side surface of the columnar structure 1 has an included angle with the bottom surface.

[0040] For example, the columnar structure 1 can be a polygonal columnar structure, for example, a rectangular straight columnar structure, a cylindrical structure or an elliptical cylindrical structure, an inclined cylindrical structure or an inclined elliptical cylindrical structure, a columnar structure with a star-shaped cross section, a straight columnar structure or an inclined columnar structure with irregular curved bottom surface and cross section parallel to the bottom surface, etc.

[0041] In some embodiments, the columnar structure 1 can be a closed geometric body formed by a plane curve rotating around an axis in the plane where the plane curve is located, and the closed geometric body is intercepted by two parallel planes. In some embodiments, the two bottom surfaces of the columnar structure 1 can have different sizes. In some embodiments, the cross section of the columnar structure 1 can have a similar shape to the bottom surface but have different sizes.

[0042] For example, the columnar structure 1 can be a circular truncated cone, a drum, or the like.

[0043] In one or more embodiments of the present specification, the columnar structure 1 is made of a transparent material. In some embodiments, the material of the columnar structure can be a glass material or a resin material. In some embodiments, the columnar structure can be made of a colorless transparent material or a colored transparent material.

[0044] Referring to FIG. 1, Figure 3 , Figure 4 In one or more embodiments of the present specification, the inside of the columnar structure 1 includes first annular regions 21 and second annular regions 22 arranged alternately from the center of the columnar structure 1 to the outside of the columnar structure 1, and the number of the first annular regions 21 is two or more.

[0045] In some embodiments, the shapes of the first annular regions 21 and the second annular regions 22 can be set based on the shape of the outer surface of the columnar structure 1. For example, when the columnar structure 1 is a rectangular columnar structure, the cross section of the first annular region 21 can be a rectangle with a smaller side length, and the cross section of the second annular region 22 can be a rectangle with a larger side length. For example, when the columnar structure 1 is a circular truncated cone, the first annular region 21 as a whole can be a conical surface with a smaller diameter excluding the top of the conical surface, and the second annular region 22 as a whole can be a conical surface with a larger diameter excluding the top of the conical surface.

[0046] In other embodiments, the shapes of the first annular regions 21 and the second annular regions 22 can also not consider the shape of the outer surface of the columnar structure 1. For example, when the columnar structure 1 is a rectangular columnar structure, the first annular regions 21 and the second annular regions 22 are both circular annular regions. For example, when the columnar structure 1 is a drum structure, the first annular regions 21 and the second annular regions 22 are both circular annular regions.

[0047] In some embodiments, the center of the columnar structure 1 is provided with the first annular region 21, and the second annular region 22 is provided outside the first annular region 21. In some further embodiments, another first annular region 21 can be provided outside the second annular region 22, and another second annular region 22 can be provided outside the other first annular region 21, so as to achieve the alternating arrangement.

[0048] In some embodiments, the first annular regions 21 and the second annular regions 22 can be alternately arranged with multiple layers. For example, each first annular region 21 and one second annular region 22 can form a group of annular regions, and the interior of the columnar structure 1 can include two or more groups of annular regions.

[0049] In some embodiments, the center of the columnar structure 1 can be provided with a first annular region 21 or a second annular region 22. For example, from the center of the columnar structure 1 to the outer surface of the columnar structure 1, the annular regions can be arranged in the order of first annular region 21, second annular region 22, first annular region 21, second annular region 22, or in the order of second annular region 22, first annular region 21, second annular region 22, first annular region 21.

[0050] In one or more embodiments of the present disclosure, the interior of the first annular region 21 has a bubble 3. In some embodiments, the interior of the second annular region 22 does not have a bubble 3. In some embodiments, the material forming the columnar structure 1 can not be microscopically dense, and the interior of the second annular region 22 not having a bubble 3 can mean that the interior of the second annular region 22 does not have a bubble 3 visible to the naked eye.

[0051] In some embodiments, the second annular region 22 forms a spacing region separating two adjacent first annular regions 21 with bubbles 3.

[0052] In some embodiments, the columnar structure 1 forms multiple rings of bubbles 3 at multiple layers of first annular regions 21. In some embodiments, two adjacent rings of bubbles 3 are separated by a second annular region 22. In some embodiments, two adjacent rings of bubbles 3 are solid structures.

[0053] In one or more embodiments of the present disclosure, the bubble 3 can be a cavity in the interior of the columnar structure 1. In some embodiments, the interior of the bubble 3 can have a gas. For example, the bubble 3 can be formed by inorganic compounds generating gas under certain conditions, such as sodium bicarbonate, ammonium bicarbonate, ammonium chloride, and sodium carbonate. For example, the bubble 3 can also be formed by compounds capable of undergoing chemical changes, such as azo compounds, sulfonyl hydrazide compounds, and nitroso compounds.

[0054] In some embodiments, the bubble 3 forms an interface between gas and solid in the interior of the columnar structure 1 (e.g., in the interior of the first annular region 21), and light passing through the interface produces reflection and refraction, thereby forming a large-angle illumination region.

[0055] In some embodiments, the bubbles 3 inside the first annular region 21 are randomly distributed. In some embodiments, the bubbles 3 inside each of the first annular regions 21 are randomly distributed. In some embodiments, a light ray can enter the inside of the columnar structure 1 along one of the bottom surfaces of the columnar structure 1, exit at a random angle after passing through two interfaces formed by one of the bubbles 3, and enter another bubble 3. Due to the random distribution of the bubbles 3, the exit of the light ray can cover a full angle.

[0056] In some embodiments, a portion of the light rays exit at random angles under the action of a large number of bubbles 3 to form a three-dimensional circumferential illumination of the columnar structure 1 (e.g., exit light rays exist on both bottom surfaces and the side surface of the columnar structure 1); another portion of the light rays exit after one or more reflections inside the bubbles 3 to light up the bubbles inside the columnar structure 1 (e.g., a visual effect formed by multiple reflections of the light rays on the inner wall of the bubbles).

[0057] In some embodiments, the shapes of the bubbles 3 can be the same or different. In some embodiments, the bubbles 3 can be circular or approximately circular. In some embodiments, the bubbles 3 are formed based on the expansion of a gas inside the columnar structure 1. In some embodiments, the bubbles 3 are formed based on the combined action of factors such as the fluid pressure of the material of the columnar structure 1 in a mold and the air pressure of the gas forming the bubbles 3 to form an approximately circular structure. In other embodiments, the bubbles 3 can also be irregularly shaped.

[0058] In one or more embodiments of the present specification, the first annular region 21 extends in the axial direction of the columnar structure 1, and the number of bubbles 3 in the first annular region 21 is a plurality. In some embodiments, the bubbles 3 in the first annular region 21 are distributed between one bottom surface and another bottom surface of the columnar structure 1.

[0059] In some embodiments, the second annular region 22 extends in the axial direction of the columnar structure 1.

[0060] In some embodiments, a toroidal region (e.g., the first toroidal region 21 or the second toroidal region 22) can refer to a portion of a spatial region in the columnar structure 1. In some embodiments, a toroidal region can include two toroidal bottom surface portions and a spatial portion extending between the two toroidal bottom surfaces in an axial direction. In some embodiments, the spatial portion of a toroidal region has a certain volume. In some embodiments, in the same first toroidal region 21, the gas bubbles 3 can be randomly distributed in a radial direction and / or an axial direction. For example, in the same first toroidal region 21, one or more gas bubbles 3 can be distributed in a radial direction, and one or more gas bubbles 3 can also be distributed in an axial direction. For example, in the same first toroidal region 21, a plurality of gas bubbles 3 can be staggered arranged in a radial direction and / or an axial direction to achieve a more uniform and complex refraction effect. For example, in two first toroidal regions 21, the gas bubbles 3 in one first toroidal region 21 can be staggered arranged relative to the gas bubbles 3 in the other first toroidal region 21 to form a more uniform overall light distribution effect.

[0061] In one or more embodiments of the present specification, in two adjacent first toroidal regions 21, the size of the gas bubbles 3 in the first toroidal region 21 closer to the center of the columnar structure 1 is greater than the size of the gas bubbles 3 in the first toroidal region 21 closer to the outer surface of the columnar structure 1. In other words, the size of the gas bubbles 3 in the first toroidal region 21 located on the inner side of the columnar structure 1 is greater than the size of the gas bubbles 3 in the first toroidal region 21 located on the outer side of the columnar structure 1.

[0062] For example, the interior of the columnar structure has two first toroidal regions, the size (e.g., the average inner diameter of the gas bubbles) of the first gas bubbles in the inner first toroidal region is greater than the size of the second gas bubbles in the outer first toroidal region.

[0063] For example, the interior of the columnar structure has three first toroidal regions, the size (e.g., the average inner diameter of the gas bubbles) of the first gas bubbles in the inner first toroidal region is greater than the size of the second gas bubbles in the middle first toroidal region; the size of the second gas bubbles in the middle first toroidal region is greater than the size of the third gas bubbles in the outer first toroidal region.

[0064] In some embodiments, the inner portion of a columnar structure has multiple layers of first annular regions, for example, two or more layers of first annular regions, and the size of the bubbles in each layer of first annular regions decreases from the inner side to the outer side. In some embodiments, the incident light is scattered outward by the bubbles in the inner first annular region to form first light rays, and the first light rays are further scattered outward by the bubbles in the middle or outer first annular region to form second light rays. In some embodiments, the larger bubbles in the inner first annular region can be used to distribute light rays to various angles, and the smaller bubbles in the outer first annular region can be used to adjust the intensity distribution of the light rays at various angles to form a more uniform and soft light effect with water ripple effect.

[0065] In some embodiments, the number of bubbles 3 in the first annular region 21 near the outer surface of the columnar structure 1 is greater than the number of bubbles 3 in the first annular region 21 near the center of the columnar structure 1 in two adjacent first annular regions 21. In some embodiments, since the bubbles in the outer first annular region are smaller, the number of bubbles in the outer first annular region can be more to refract more times and more densely to form a soft light effect.

[0066] Figure 7 is a light ray diagram of a single-bubble light guide column according to some embodiments of the present disclosure, as shown in Figure 7 As shown, the bubbles in one annular region distribute light rays to various angles to form multiple bright-dark transition parts with different intensities. Figure 8 is a light ray diagram of a multi-bubble light guide column according to some embodiments of the present disclosure, as shown in Figure 8 As shown, the bubbles in multiple annular regions not only distribute light rays to various angles, but also further form a more uniform and soft light effect, and the light effect also forms a certain water ripple effect.

[0067] In one or more embodiments of the present disclosure, as shown in Figure 5 , Figure 6 The columnar structure 1 can be provided with a receiving space 11 for accommodating other mechanisms. In some embodiments, the receiving space 11 can have an upper bottom surface and a side surface. In some embodiments, the side surface of the receiving space 11 can be provided with threads to be connected to other mechanisms.

[0069] In some embodiments, one end of the first housing 41 is fixedly connected to the light guide column. In some embodiments, the second housing 42 is fixedly connected to the first housing 41, and the second housing 42 encloses the other end of the first housing 41. In some embodiments, the first housing 41 and the second housing 42 form a housing for accommodating the light source mechanism 5. In some embodiments, the first housing 41 and the second housing 42 can form a lamp head (e.g., a connection portion of the light source to an external power source). In some embodiments, the light source is connected to electricity through the lamp head, thereby generating a light emission phenomenon. In some embodiments, the light source mechanism 5 is disposed in a first accommodating space 43 formed by the first housing 41 and the second housing 42, and the first housing 41 has a stepped portion, and the light source mechanism 5 is arranged on the stepped portion.

In some embodiments, the diameter of the first cylindrical structure 411 is greater than the diameter of the third cylindrical structure 413, the second annular structure 412 has a stepped face forming a stepped portion, and the circuit board 51 of the light source mechanism 5 is fixed to the second annular structure 412.

In some embodiments, the light emitting units can be disposed in the first cylindrical structure 411. In some embodiments, the light emitting units can be disposed towards the light guide column. In some embodiments, the electrical devices can be disposed in the third cylindrical structure 413.

[0071] In some embodiments, the circuit board can be annular, and one or more LED light emitting units can be arranged on the circuit board. In some embodiments, multiple turns of LED light emitting units can be arranged on the circuit board. In some embodiments, the outer diameter of the circuit board can match the diameter of the light guide column. In other embodiments, the outer diameter of the circuit board can also be smaller than the diameter of the light guide column.

[0072] In some embodiments, the columnar structure 1 of the light guide column has a second accommodating space 11, and at least a portion of the first housing 41 is disposed in the second accommodating space 11. In some embodiments, the outer wall of the first housing 41 can be provided with external threads matching the inner wall of the second accommodating space 11.

[0073] In one or more embodiments of the present disclosure, referring to Figure 16 As shown, the lamp further comprises a light uniformizing sheet 6 (or light uniformizing cover) disposed in the second accommodating space 11. In some embodiments, the light uniformizing sheet 6 has a sheet structure. In some embodiments, the light uniformizing sheet 6 can be milky white. In other embodiments, the light uniformizing sheet 6 can also be provided in other colors. In some embodiments, the light uniformizing sheet 6 can be translucent. In some embodiments, the light uniformizing sheet 6 is hidden in the second accommodating space 11, so that the user can only see the transparent structure (e.g., the columnar structure 1) when observing the lamp, and cannot observe the large-area milky white light uniformizing cover.
