Description

Technical Field

[0001] The invention relates to the field of light-emitting optical devices and light-emitting equipment, and in particular to an LED long afterglow composite light-emitting lens and a light-emitting equipment containing the LED long afterglow composite light-emitting lens structure. Background Art

[0002] Long afterglow luminescent material, also known as luminous material, is a photoluminescent material: when excited by a light source, it emits visible light and stores part of the light energy obtained. After the excitation stops, the energy is slowly released in the form of light. The brightness of the light is related to the performance of the luminescent material itself, as well as the thickness of the long afterglow luminescent layer and the concentration of the long afterglow luminescent powder therein. Due to the continuous development and progress of LED combined with long afterglow technology, the brightness of the light of long afterglow materials has been greatly improved. In recent years, it has gradually been paid attention to and applied to various lighting equipment fields. It has been welcomed by the market and consumers, forming industry and local standards, and has formed industrial development.

[0003] The existing photoelectric long afterglow luminous bodies are mainly divided into the following three categories:

[0004] One type uses a coating method to set a long afterglow luminescent material layer or cover a luminescent film on the surface of the luminescent body, represented by Patent No. 100467938C and CN 204328843 U. The long afterglow is excited by the electroluminescent body, and part of the light is emitted through the long afterglow. Due to the limitation of the manufacturing process, the thickness of the long afterglow luminescent material layer generally does not exceed 1mm, so the afterglow brightness is too low, and it is difficult to meet the practical requirements of long afterglow luminescence;

[0005] One type is to mix the long afterglow luminescent powder with the light-guiding medium and then make a long afterglow luminescent shell through extrusion, injection molding or molding process, represented by patent numbers CN 101776213 B, CN 205723621 U, CN 104170103A, and CN 206890416U. This method can make the long afterglow shell have a sufficient thickness. Although the long afterglow can be fully excited by the LED light-emitting device in the shell, the light transmittance of the LED light-emitting device in the long afterglow shell is low, so that its brightness decays too much, thereby greatly weakening or even completely losing its original luminous function, and because of the matching of the excitation curve, the luminous color of the original luminous body is greatly restricted, so that the diversity of the luminous color of the LED long afterglow luminous body is limited, and the luminous color is mixed with the afterglow luminescence, resulting in a shift in the luminous color, impure luminescence, color difference, and high production cost;

[0006] Another type is to directly mix the long afterglow luminescent powder with the light-guiding medium above the light-emitting device, such as the LED array light board, and then pour and solidify it, or to form a patch composite.

[0007] In conclusion, in the long afterglow optoelectronic products of the prior art, the long afterglow material is basically arranged in a flat covering manner in combination with the LED, and is mainly formed by liquid casting and leveling, and is mainly in a layered form. The LED is arranged below or inside the long afterglow material. Only the SMD (surface mount) LED has a good luminous effect, and the luminous effect of LEDs of other packaging methods is not ideal. Some products also have a light-transmitting protective panel above the long afterglow luminous layer; the luminous effect of the arrangement in which the long afterglow material is in contact with the LED is the main one. When the LED emits light, part of the light energy excites the long afterglow, and part of the light energy that is not converted is scattered and emits light after passing through the long afterglow luminous layer. Therefore, the prior art products must have the following defects:

[0008] 1. The long afterglow luminous layer is mainly excited by transmission. At present, LEDs mainly include SMD (chip type), COB (integrated type), LAMP (direct plug-in type) or imitation lumen lamp beads. Their packaging methods, product shapes, sizes, specifications, luminous performance, welding methods, and usage focuses are different. Some LEDs already have one-time packaging transmission. In particular, the height (thickness) between the top of the LED luminous body and the circuit board layer is different. Therefore, the thickness of the long afterglow luminous layer above the LED and around the LED is uneven. Generally, the long afterglow luminous layer above the LED is not uniform. The thickness of the light layer is smaller than the thickness of the long afterglow light-emitting layer on the side of the LED, which may easily cause the thickness of the long afterglow light-emitting layer above the LED to be too thin, resulting in insufficient afterglow brightness, or the thickness of the long afterglow light-emitting layer on the side of the LED to be too thick, resulting in insufficient excitation of the long afterglow light-emitting layer, causing waste of light energy; and the long afterglow material of the existing LED long afterglow light-emitting body is difficult to be made into various three-dimensional shapes, and the three-dimensional light-emitting effect is not good, so that its light-emitting angle, especially the side light-emitting angle, is limited; in short, the LED light energy utilization rate is low, and the light-emitting effect and LED light distribution emission effect are poor.

[0009] 2. Since the long afterglow luminous layer is arranged above the LED luminous body, the LED light is absorbed and scattered by the long afterglow powder when it is emitted through the long afterglow layer, which will cause excessive loss of LED output light intensity and poor directivity (the output light loses its directionality), making it difficult to achieve the purpose of output designed according to the optical path [facilitating the realization of parameters such as luminous angle, beam angle or light intensity distribution, such as focusing or divergence or deflection (the main light beam is emitted at an acute angle to the main axis of the light emission) or polarization (sometimes called side light, the output light energy distribution on one side is greater than the output light energy distribution on the other side)], etc., especially in luminous equipment that needs to have fixed-point (area) projection for lighting purposes or directional (angle) projection for indication purposes. In addition, the existing products have a short luminous range and a short viewing distance, which is particularly not conducive to the requirements of long viewing distance for transportation, security, emergency and other purposes, and the scope of use is limited.

[0010] 3. The long afterglow luminous layer covers the top of the LED luminous body. The light emitted by the LED luminous body through the long afterglow luminous material is mixed with the long afterglow stimulated light, resulting in impure luminescent color and color shift. As a result, the long afterglow stimulated light has too much influence and interference on the luminescent spectrum such as the color quality or color temperature of the LED luminous device, affecting the luminescent spectrum of the original LED: when the white light LED for lighting purposes is used as the excitation light source, it seriously affects the quality of the white light spectrum. When other colors of excitation light sources are used, it will affect the luminescent color, resulting in limited application range.

[0011] In conclusion, the long afterglow luminescent products in the prior art have the above-mentioned fatal defects and some other shortcomings, which restrict their development and become a difficult problem that needs to be solved urgently in the industry. Summary of the invention

[0012] In view of the above problems, the technical problem to be solved by the present invention is:

[0013] The light energy ratio of the emitted light part of the LED luminous body and the excitation light part for exciting long afterglow luminescence can be allocated according to design requirements, and the light energy utilization rate is high. It can choose to focus on the advantages of the LED's own luminescence and take into account the long afterglow luminescence function, or it can choose to focus on the advantages of the long afterglow luminescence and take into account the LED's own luminescence function. The luminous effect (LED luminous effect and long afterglow luminous effect) or the light distribution emission effect is good, and it has the dual functions of LED light distribution function and long afterglow luminescence, which can solve the defects of the existing LED long afterglow luminous devices, can be applicable to various types and specifications of LEDs, and is easy to manufacture and install in the later stage. It can serve as a LED long afterglow luminous lens structure of a general device to solve the problems that plague the development of the industry;

[0014] In particular, the output light field can be redistributed and adjusted, so that at least part of the main light beam emitted by the LED luminous body can be emitted according to the light path design [to facilitate the realization of parameters such as luminous angle, beam angle or light intensity distribution, such as focusing or divergence or deflection (the main light beam is emitted at an acute angle with the main axis of luminescence) or polarization (sometimes also called side light, the output light energy distribution on one side is greater than the output light energy distribution on the other side)], so that the output light can meet the needs of fixed-point (regional) projection or directional (angle) projection of the main light beam, and the influence of dark areas on lighting and projection caused by shading of the long afterglow luminous molding body can be eliminated or partially eliminated by expanding the luminous angle of the output light (single-sided expansion angle or double-sided expansion angle or multi-sided expansion angle, expanding the beam angle);

[0015] While retaining the afterglow of the long afterglow luminous body, the LED is made to emit in its original color (original luminous performance, luminous wavelength). It is more suitable for white light LEDs and dual-chip packaged LEDs or multi-chip packaged LEDs (two-color or multi-color luminescence) with different luminous wavelengths, reducing the light interference (chromaticity shift, etc.) caused by the long afterglow stimulated luminescence on the LED luminescence.

[0016] It can also bring many other advantages, such as achieving the afterglow brightening effect of superimposing the light on the adjacent parts of the long afterglow when the afterglow is long (usually in a ring shape) and forming a luminous virtual ring of afterglow on the light incident surface or the light exit surface, which has a brightening effect; a microstructure can be set on the lens to make the incident light outside the lens produce a local angle reflective effect on the light incident surface, the total reflection surface or the light exit surface. When combined with a TIR lens, it can also produce a better reflective effect on the total reflection surface, and also has a retroreflective function.

[0017] The volume of the LED long afterglow composite light-emitting lens can be large or small. A small one can serve as a composite light-emitting lens for a single LED, and a large one can serve as a lens for an integrated packaged LED or as a lamp shell or lamp surface of an LED light-emitting device. It can be used as an LED non-imaging lens that focuses on secondary light distribution, and also has long afterglow luminescence, so that the lens has an afterglow luminescence function. The LED long afterglow composite light-emitting lens can also be used as a long afterglow luminous body that focuses on long afterglow luminescence, and the long afterglow luminous body has the light distribution function of the lens. And through the light distribution design, the L The ED light-emitting device has directional emission and original luminous properties (conventional luminous properties such as luminous wavelength, chromaticity or color temperature), and can also have a high-brightness afterglow luminous function. After the light distribution design, it can also play a role in brightening the afterglow luminescence. After the light distribution design, it can also achieve the design purpose through the light field distribution of the emitted light and reduce the negative impact of the long afterglow luminous molding on the original LED long afterglow luminous body when it is stimulated to emit light [the long afterglow luminous molding shading (absorption and scattering) causes the light intensity to weaken, resulting in the dark area of ​​light projection. The impact on lighting, projection, etc. can be eliminated or partially eliminated. The LED long afterglow composite luminous lens can achieve higher light energy utilization, better versatility, better luminous performance, higher integration and standardization, high convenience, wider applicability, and can meet various different lighting needs. It can be used in special luminous fields mainly for indicating luminescence or induced luminescence, and can be used in conventional luminous fields mainly for lighting.

[0018] The LED long afterglow composite luminous lens, by combining with the long afterglow luminous molding, not only solves the defects of the existing long afterglow luminous equipment, but also increases the functions of the existing long afterglow luminous equipment. It can have the function of long afterglow luminous, and can also play the functions of focusing, diverging, deflecting or polarizing to achieve light distribution emission. It can be used for fixed point (region) light projection or directional (angle) projection, improves its comprehensive luminous performance, has more application value in the field of security luminous, and expands its use and application field. It is particularly suitable for white light LED light sources and other color light sources, and can directly act as a luminous lamp shell, or be placed in a transparent protective lamp shell (such as a tempered glass shell) or a metal bottom shell to act as a luminous equipment.

[0019] The lens can be combined with an LED to make an LED or an LED luminous body with an afterglow luminous function, such as a point light source, a strip light, a panel light, a modeling light, etc., and is more suitable for making an LED long afterglow luminous body with a three-dimensional luminous effect. It can serve as a local structure for various luminous devices or equipment, or be made into various general luminous optical standard devices and equipment; it can directly serve as a luminous lamp shell, or serve as an integrated luminous device or equipment, so that it can be used not only in the fields of transportation, fire protection, emergency, etc., such as being installed on vehicles and other means of transportation to play the role of displaying the body contour, but also being installed on transportation facilities, such as road surfaces, walls, and guardrails, to play the role of indicator lights or contour lights, and can be expanded to conventional luminous fields such as conventional white light illumination and multi-color luminous fields, thereby solving the difficulties of the prior art.

[0020] The principle of light distribution of this light is: according to the light-emitting performance of the LED light-emitting body (LED is generally a Lambertian body, such as Figure 3 As shown in FIG. 1 , the lens body is used as the supporting substrate of the long afterglow luminous molding. The volume or area ratio corresponding to the position where the long afterglow is located and the direction of the solid angle are set according to the solid angle of the LED, so as to allocate the light energy ratio of the emitting light part of the LED luminous body and the excitation light part for stimulating the long afterglow luminescence according to the design needs. Taking the typical application of LED long afterglow composite luminous lens as an example, as shown in FIG. Figure 4 As shown:

[0021] The total luminous flux of the LED light source (Lambertian body) is about

[0022]

[0023] Right now

[0024] The luminous flux of the LED luminous body (Lambertian body) used to stimulate long afterglow luminescence is about

[0025]

[0026] Right now Wherein, θ is the angle of the light-emitting direction deviating from the vertical axis (corresponding to the axis passing through the center of the central accommodating cavity and perpendicular to the bottom surface of the lens housing), θ 1 / 2 is the half-value angle of the LED light source, φ is the angle on the bottom surface of the lens corresponding to the light-emitting direction (polar coordinates are established on the bottom surface of the corresponding lens with the light-emitting center as the origin), and I(θ) is the luminous intensity of the LED light source in the θ angle direction.

[0027] Therefore, the light energy ratio of the emitted light part of the LED luminous body (Lambertian body) and the excitation light part used to excite the long afterglow luminescence is

[0028] η=φ' / φ;

[0029] The lens body structure plays the role of an LED light energy distributor, that is, the light intensity of the LED at the solid angle position where the long afterglow is located is used to excite the long afterglow. When the long afterglow is stimulated to emit light, it is understood as a non-directional scattered light source. At this time, the long afterglow material is stimulated to emit light and the LED emits light in superposition, and the rest still follows the original directional light emission and light spectrum of the LED. The light energy distribution is completed on the LED lens to achieve the original light emission and the light energy distribution for exciting the long afterglow. The overall light energy utilization rate is high, the light effect (LED light effect and long afterglow light effect) and the light distribution emission effect are good, and it can meet the requirements of multi-color light emission (even the full visible light spectrum segment light emission);

[0030] And because the size of the LED is small and the size of the lens is large, the light-emitting area of ​​the LED can be enlarged by the lens, or the light beam of the LED can be expanded to excite the corresponding long-afterglow light-emitting molding with a larger area, thereby expanding the light-emitting surface, making the operation error smaller and easier to operate;

[0031] The lens can also act as a secondary light distribution for the LED output light field. Especially when combined with TIR, it can focus the LED output along the main axis of light emission, and also brighten the long afterglow light, further improving the light-emitting performance.

[0032] The design idea of ​​the present invention can be understood as follows: since the LED light-emitting body is a Lambertian body, the closer to the main axis of the light emission, the greater the light intensity, and the farther away from the main axis of the light emission, the smaller the light intensity; if emphasis is placed on the long afterglow luminous effect, the long afterglow luminous molding should be close to the solid angle position of the luminous axis of the LED, so that the long afterglow luminous molding can be fully excited to increase the long afterglow luminous brightness, or / and increase the solid angle ratio or area ratio of the long afterglow luminous molding to increase the luminous area of ​​the long afterglow luminous molding; if emphasis is placed on the secondary light distribution emission effect of the LED, the long afterglow luminous molding should be far away from the solid angle position of the luminous axis of the LED, reduce the excitation light intensity of the long afterglow luminous molding to appropriately reduce the long afterglow luminous brightness, or / and reduce the solid angle ratio or area ratio of the long afterglow luminous molding to appropriately reduce the luminous area of ​​the long afterglow luminous molding.

[0033] Furthermore, the present invention also provides a Fresnel ring on the first light incident surface (which can focus light along the main axis of light emission), or a Fresnel ring is also provided on the light emitting surface portion of the top surface corresponding to the first light incident surface. The diameter of the Fresnel ring can be more than 20 mm, so the lens can be made larger and thinner, and can carry a longer afterglow luminous molding with a larger area.

[0034] Furthermore, the present invention provides a downwardly opening accommodating groove at the bottom or side of the light-transmitting body near the outer edge, in which a long afterglow luminous body is combined. The light emitted by the LED luminous body can be totally reflected by the top surface or the side outer wall to excite the backlight surface (toward the observer) of the long afterglow luminous body, thereby solving the problem that when the long afterglow luminous body is thick and the luminous intensity of the excitation light source is low, the backlight surface is not easy to be fully excited and the brightness is low, so that the weak light excitation effect of the LED luminous body is good and the power of the LED luminous body can be saved at the same brightness; it can also achieve the afterglow brightening effect (generally in a ring shape) of superimposed luminescence in the area between adjacent luminous surfaces of the long afterglow luminous body (generally in the area close to the luminous axis) during long afterglow luminescence, and the long afterglow luminous body will form a luminous contour after refraction and reflection on the surfaces of the lens body, so that the long afterglow luminous effect is better.

[0035] The technical solution of the present invention is: an LED (but not limited to LED) LED long afterglow composite light-emitting lens (the lens in this article is a general lens, including a spherical lens, an aspherical lens, a prism, or a combination of the above lenses, which can be large or small in size, a small one can serve as a composite light-emitting lens for a single LED, a large one can serve as a lens for an integrated packaged LED or as a lamp shell or lamp surface of an LED light-emitting device), such as Figure 1 , 8 As shown, it comprises a lens body structure (1) (sometimes also called a lens shell) and a long afterglow luminous molding (2) [generally a molding obtained by mixing long afterglow luminous powder and a liquid or molten light-transmitting mixed medium in a certain proportion and then solidifying, and the light-transmitting mixed medium and the transparent light-guiding medium (3) can be made of the same or different materials] on the lens body structure (1) by means of a transparent light-guiding medium (3) [including a transparent light-guiding glue, a light-transmitting resin (liquid or solid at room temperature) or other light-transmitting mixed medium] in a liquid state (preferably casting, sometimes also called dripping or dispensing) or a molten state (preferably injection molding) manner;

[0036] The long afterglow luminescent molding (2) is a solidified molding obtained by mixing long afterglow luminescent powder and a light-transmitting mixed medium in proportion and forming the solidified ... The center portion of the bottom (bottom surface) of the lens body structure (1) or the portion close to the center portion is inwardly recessed to form a center accommodating cavity (1A) with an opening facing downward that can accommodate an LED; the long afterglow luminous molding (2) is coupled to the lens body structure (1) via an accommodating groove (1B) or a fitting structure (1D); a transparent light-guiding medium (3) is provided on the coupling surface between the light distribution optical main body (11) and the long afterglow luminous molding (2); the coupling surface is a light-guiding coupling surface (1e) [at least part of the light from the LED excites the long afterglow luminous molding (2) via the light-guiding coupling surface (1e); the long afterglow luminous molding (2) emits light outwardly via the light-guiding coupling surface (1e)];

[0037] The axis passing through the center of the central accommodating cavity and perpendicular to the bottom surface of the lens shell is its vertical axis. The bottom of the light distribution optical main body (11) with the central accommodating cavity (1A) is the lighting part [that is, the central accommodating cavity (1A) is surrounded by the lighting part]. The bottom of the lighting part is provided with a lighting part bottom surface (1b) surrounding the central accommodating cavity (1A) [playing the role of support, structural transition, limit or positioning (for fixing LED or circuit board), auxiliary light guide, etc., generally a plane, on which a limit groove or bracket for accommodating LED can be provided], and the upper part of the corresponding lighting part is the light output part; Figure 2As shown, the inner wall (but not limited to the inner wall) of the central accommodating cavity (1A) of the light-collecting portion is a light-entering surface (1a) (generally a free-form surface), the top surface of the light-exiting portion or / and the outer side surface of the peripheral portion (12) connected to the light-exiting portion is a light-exiting surface (1f) (generally a free-form surface), and at least a portion of the light-entering surface (1a) and the light-exiting surface (1f) respectively form a portion between the light-entering surface (1a) and the light-exiting surface (1f) that can transmit part of the light emitted by the LED in or below the central accommodating cavity (1A). The optical structure is characterized in that the light beam is refracted or reflected in the lens body structure (1) through the light incident surface (1a) and does not pass through the light guide coupling surface (1e), and is transmitted from the light exit surface (1f) to the outside with the original light emission spectrum of the LED, and the optical structure (the corresponding parts of the above two are not parallel planes) enables the LED part of the emitted light to have a light distribution emission function (usually also called secondary light distribution, the secondary distribution of the light field in the solid angle direction corresponding to the light path emitted by the LED, especially the directional emission of the part of the light that is absorbed, scattered and disturbed by the long afterglow luminous molding body) to achieve the purpose of fixed point (region) light projection or directional (angle) projection, and can compensate for the dark area of ​​light projection caused by the weakening of the emitted light intensity and the shift of the hue due to the shading of the long afterglow luminous molding body, and a light excitation channel (generally after refraction or reflection) is formed between the light incident surface (1a) and the long afterglow luminous molding body (2) so that the light emitted by the LED in the central accommodating cavity (1A) or below is transmitted to the long afterglow luminous molding body (2) A channel [may pass through the light-guiding coupling surface (1e) or other paths] is formed between the long afterglow luminescent molding (2) and the light-emitting surface (1f), so that when the LED emits light, the stimulated light of the long afterglow luminescent molding (2) passes through the light-guiding coupling surface (1e) and is refracted or reflected to emit light outward from the light-emitting surface (1f); and after the LED is turned off, part of the afterglow light passes through the light-guiding coupling surface (1e) and is refracted or reflected to emit light outward from the light-emitting surface (1f).

[0038] The LED long afterglow composite light-emitting lens can achieve light energy distribution through optical matching between the LED and the optical structure of the light distribution optical main body (11) so that part of the light is incident on the long afterglow light-emitting molding (2), and another part of the light maintains the original light emission spectrum of the LED (mainly referring to the light emission wavelength, chromaticity, or color temperature such as white light) and is emitted outward from the light emission surface (1f) along the light emission path according to the light distribution design, and in particular, can form directional emission;

[0039] When the LED emits light, according to the proportion of light energy, a portion of the light is emitted from the light emitting surface (1f) along the light emitting path in accordance with the required emission light field distribution requirements while maintaining the original emission spectrum of the LED; at the same time, another portion of the light is transmitted to the long afterglow luminous molding (2), so that the long afterglow luminous molding (2) is stimulated to emit light;

[0040] like Figure 5 As shown, after the LED is turned off, the long afterglow luminous molding (2) maintains afterglow luminescence in the form of brightness attenuation, and the light emitted by it is emitted outward from the light emitting surface (1f) through the light guide coupling surface (1e);

[0041] Thus, an LED long afterglow composite light-emitting lens is formed, in which a long afterglow light-emitting molding (2) is provided in a local area, at least the light distribution optical main body (11) is a transparent body, and has LED light distribution and emission [after the light emitted by the LED is distributed by the lens (light energy distribution), part of the light maintains the original light emission spectrum of the LED and is secondary distributed and emitted from the light emitting surface (1f) along the light emission path] and LED light distribution and excitation long afterglow light emission function [after the light emitted by the LED is distributed by the lens (light energy distribution), part of the light is incident on the long afterglow light-emitting molding (2), so that the long afterglow light-emitting molding (2) is stimulated to emit light, and when the LED is turned off, the long afterglow light-emitting molding (2) emits light outward from the light emitting surface (1f) through the light guide coupling surface (1e). The lens has a three-dimensional light-emitting effect (expanding the viewing angle) and has an afterglow brightening effect at a specific three-dimensional angle or in a local area.

[0042] Preferably, the lens body structure (1) comprises a light distribution optical main body (11) made of a transparent material, which is mainly used to adjust the light energy distribution ratio of the LED output light and the excitation light of the long afterglow luminous molding (2), and performs secondary light distribution on the LED output light and acts as an optical main body structure, and a peripheral part (12) surrounding the light distribution optical main body (11) and connected with its outer side (can be assembled into a whole by secondary light guide glue) [the peripheral part (12) is transparent or partially transparent or opaque, preferably transparent or partially transparent, and mainly acts as a barrier. In particular, the long afterglow luminous molding (2) can act as the peripheral part (12)], a molded optical structure (can be molded as a whole at one time, or transparent components can be glued into a whole piece in batches), and the lens body structure (1) has at least one vertical axis passing through the central accommodating cavity (1A) [corresponding to the vertical axis passing through the center of the central accommodating cavity The axis of the central cavity (1A) and perpendicular to the bottom surface of the lens shell generally corresponds to the light-emitting axis of the LED (in this case, the light-emitting axis of the LED passes through the center of the central cavity and is perpendicular to the bottom surface of the lens shell). When the central cavity (1A) is rotationally symmetrical, it is the vertical plane of the rotation axis. The lens body structure (1) is a symmetrical body that is left-right symmetrical (correspondingly left-right symmetrical or front-back left-right symmetrical) along the vertical plane. The long afterglow luminous molding (2) is combined with the portion between the side wall of the central cavity (1A) and the peripheral portion (12) through a receiving groove (1B) or a fitting structure (1D), or is combined with the peripheral portion (12), or is combined with the top or side wall of the central cavity (1A). A transparent light-guiding medium (3) is provided on the combined surface of the light-distributing optical main body (11) and the long afterglow luminous molding (2), and the combined surface is a light-guiding coupling surface (1e).

[0043] Furthermore, the portion between the light distribution optical main body (11) and the peripheral portion (12) [the portion between the side wall of the central accommodating cavity (1A) and the peripheral portion (12)], or the top of the central accommodating cavity (1A) is recessed inwards according to the position to form an accommodating groove (1B) [similar to a ditch (suitable for pouring or dripping liquid luminescent material)] around the vertical axis or center point (corresponding to the center position of the accommodating cavity for arranging the LED) or the central accommodating cavity (1A) which can be used to combine with the long afterglow luminescent molding (2) The accommodating groove (1B) can be a polygonal ring or a molding ring, preferably a circular ring or a regular hexagonal ring (honeycomb shape) when viewed from above along the vertical axis. The "surrounding" can be symmetrically around the central axis (or center point), or non-symmetrically around the vertical axis. It can be circular or non-circular (such as a polygonal ring, an elliptical ring or an eccentric ring, etc.), and the accommodating groove (1B) can be connected or segmented (for example, a discontinuous ring surrounded by multiple arc segments when viewed from above along the vertical axis);

It can allocate the light energy proportion of the output light part of the LED light source and the excitation light part for exciting long afterglow luminescence according to design requirements, and has a secondary light distribution function for the output light field.

[0133] Long afterglow luminous molding (2):

[0134] The long afterglow luminescent molded body (2) is a solidified product obtained by mixing a long afterglow luminescent powder with a liquid or molten light-transmitting mixed medium, and then curing by heating or reaction curing or by injection molding or molding. The long afterglow luminescent powder is an energy storage luminescent material, and preferably a rare earth-doped alkaline earth aluminate or silicate with good luminescent performance is selected. For example, Sr4Al 14 O 25 or yellow-green SrAl2O 4， Or a mixture of the two in a certain proportion.

[0135] The long afterglow luminescent molding (2) can be pre-molded and combined with the lens body structure (1) by a matching method and by a transparent light-guiding medium (3) in a liquid solidification method or a molten solidification method according to the corresponding position; or it can be directly poured into the cavity of the lens body structure (1) by mixing the long afterglow luminescent powder with a liquid or molten light-transmitting mixed medium and solidifying it.

[0136] Preferably, the long afterglow luminescent molded body (2) emits light in two colors, such as a combination of red or orange and blue-green.

[0137] Transparent light-guiding medium (3) and light-transmitting mixed medium:

[0138] The transparent light-guiding medium (3) mainly acts as a light-guiding medium or a bonding and curing agent, and is mainly a light-guiding adhesive, and can be used to bond and fix various materials or components, and play a role in guiding light, such as being used to bond the long afterglow luminous molding (2) to the lens body structure (1).

[0139] The light-transmitting mixed medium mainly acts as a solidifying and molding medium mixed with the luminescent powder. It is a transparent or light-transmitting organic medium or inorganic medium [generally a mixture] that can be in liquid or molten state under certain conditions, can be mixed with solid powder and can be solidified and molded under certain conditions. Some are liquid at room temperature, and some are solid. The solid liquid or molten transparent light-guiding medium (3) can be converted into a liquid or molten state by heating or other methods. It is generally a liquid transparent adhesive, or a liquid or solid transparent resin, including a main material and its related additives (curing agent, accelerator, flux, dissolving liquid, stabilizer, dispersant, thickener, antioxidant, leveling agent, defoaming agent, etc.), wherein the main material of the organic medium is generally epoxy resin or silicone resin or polyurethane resin or PVC resin or PET resin or acrylic resin or fluorocarbon resin, etc., and the main material of the inorganic medium is generally glass or quartz, etc.

[0140] The transparent light-guiding medium (3) and the light-transmitting mixed medium are sometimes made of the same material and can be used in place of each other, and sometimes are made of different materials and cannot be used in place of each other. For example, when a liquid casting process is used, the light-transmitting mixed medium acts as the transparent light-guiding medium (3), and the two are made of the same material. When the long afterglow luminous body is made by injection molding or other processes, the light-transmitting mixed medium is a solidified molding medium mixed with luminescent powder, and the transparent light-guiding medium (3) can use a different transparent light-guiding glue, for example, the light-transmitting mixed medium is a transparent PMMA or PC material, and the transparent light-guiding medium (3) can use a transparent epoxy material, and the two are different materials.

[0141] LED(4):

[0142] The LED (4) may be an LED, a fluorescent lamp or other organic or inorganic light source, and may be an LED light source whose luminous spectrum has a wavelength range within the wavelength range of the excitation spectrum of the long afterglow luminous molding (2), or may be an LED light source whose wavelength range intersects, overlaps or covers the wavelength range of the excitation spectrum of the long afterglow luminous molding (2), or may be a mixed light LED comprising at least two or more light-emitting diodes and having two or more main luminous wavelengths, or may be a visible light LED light source combined with a UV auxiliary light source corresponding to the excitation spectrum of the long afterglow luminous molding (2), or may be an integrated packaged RGB LED, RGBW LED, RGB UV LED or RG UV LED, or may be a COB packaged dual-color or multi-color LED light source, and may be a SMD LED or a direct-insert LED soldered on a circuit board.

[0143] The LED (4) can be a point light source, a dot matrix light source, a surface light source, or a combination of two or more of the above.

[0144] The LED (4) can be a single light source, or a combination of two or two groups, a plurality or a plurality of groups, light sources with the same wavelength or different wavelengths, and the same packaging method or different packaging methods.

[0145] The smallest LED (4) is a light emitting diode.

[0146] Circuit board layer (5):

[0147] The circuit board layer (5) may be a flexible or rigid circuit board, and may be connected to external wires or electrodes or control circuits.

[0148] At the simplest level, the circuit board layer (5) can act as the encapsulation layer (6).

[0149] The main advantages of the LED long afterglow composite light-emitting lens of the present invention and the light-emitting device containing the LED long afterglow composite light-emitting lens structure are:

[0150] 1. It can be applied to different types of LEDs, and can allocate the proportion of the light energy of the emitted light part of the LED luminous body and the excitation light part used to excite the long afterglow luminescence according to the design requirements. It can choose to focus on the advantages of the LED itself, or focus on the advantages of the long afterglow luminescence. It can also make the long afterglow energy fully excited, and try to avoid the oversaturation of the excitation light energy of the long afterglow luminous molding, reducing unnecessary waste of light energy.

[0151] 2. It can perform secondary light distribution on the outgoing light field, which can make the LED emit in a direction according to the preset light distribution design [to facilitate the realization of parameters such as luminous angle, beam angle or light intensity distribution, such as focusing or divergence or deflection (the outgoing main light beam is emitted at an acute angle to the main axis of light emission) or polarization (sometimes called side light, the light energy distribution on one side is greater than the light energy distribution on the other side), etc.], so that the outgoing light meets the needs of fixed-point (regional) projection or directional (angle) projection of the main light beam, and can make the long afterglow emit non-directional scattered light according to the preset light distribution design, and can also reduce the negative impact of the long afterglow on the original LED light emission through the light field distribution of the outgoing light, and eliminate or partially eliminate the influence of the dark area caused by the shading of the long afterglow light-emitting molding on the lighting and projection by expanding the luminous angle of the outgoing light (single-sided expansion angle or double-sided expansion angle or multi-sided expansion angle to expand the beam angle).

[0152] 3. It can maintain the original luminous properties of LED light-emitting devices to the maximum extent (conventional luminous properties such as luminous wavelength, chromaticity or color temperature), and can also have high-brightness afterglow luminous function and can emit multi-color light.

[0153] 4. It can also bring many other advantages, such as achieving the afterglow brightening effect of superimposing the light on the adjacent parts of the long afterglow when the afterglow is emitted (generally in a ring shape) and forming a virtual ring of afterglow light on the light incident surface (1a) or the light exit surface (1f), which plays a brightening role; a microstructure can be set on the lens so that the incident light outside the lens produces a local angle reflective effect on the light incident surface (1a), (1c) and the light exit surface (1f). When combined with a TIR lens, it can also produce a better reflective effect on (1c), and has a retroreflective function.

[0154] 5. Since the volume of LED is relatively small, there will be large errors in the distribution of light sources and the setting of long afterglow luminous moldings. This can easily lead to unreasonable distribution of light sources, resulting in waste of light energy and failure to achieve the original design purpose. If the long afterglow luminous molding is set farther away from the LED light-emitting body, although the error can be reduced, the long afterglow luminous molding cannot be fully excited because the illumination of the excitation light of the LED light-emitting body decreases with the distance, and thus the expected long afterglow luminous brightness effect cannot be achieved. The lens body of the present invention uses the long afterglow luminous molding as a space carrier and a transmission carrier of the light path. The operation can be simplified and the matching error can be reduced by the proportion of the light path of the long afterglow luminous molding on the lens body and the light output area. For example, precise control can be achieved by adjusting the height, width, depth, etc. of the long afterglow luminous molding, and it can be well implemented with the help of simulation software such as Lighttools, Solidwork, TracePro, etc.

[0155] 6. Since the lens and the long afterglow luminous molding are integrated into one, the integration is higher and the performance is wider; it can be modularized or in the form of standard parts, which can control the performance and quality of the product, reduce the production cost and the cost of use, facilitate the improvement of production efficiency, facilitate industrialization and industrialization, and promote the development of the industry.

When the second and fourth light rays reach the second-level TIR total reflection surface (110C2) on one side of the convex rib, most of them will be reflected to the second-level TIR total reflection surface (110C2) on the other side of the convex rib, and then emitted from the light-emitting surface (110f) of the lens body after being reflected by the two second-level TIR total reflection surfaces (110C2). The reflectivity of the grained free-form surface treated with graining increases, which can increase the amount of the fourth light ray, thereby increasing the brightness of the light emitted at the edge of the lens light-emitting surface, avoiding the concentration of light at the center of the aperture, and helping to improve the quality of lighting.

[0314] The lens body structure (310) can be made of acrylic or PC injection molding, and can be integrally molded or separately molded, that is, the light distribution optical main body (3110) and the transparent surrounding edge (3120) are integrally molded; or the light distribution optical main body (3110) is integrally molded, and a commercially available lens can be selected to replace it, and it is glued together with the transparent surrounding edge connected to the transparent top cover through a light guiding medium (330).

[0315] Preferably, the angle between the plane where the prism stripes are located and the horizontal plane is 10° to 80°. In other words, the prism stripes are not parallel to the horizontal plane, but are at an acute angle. This inclined structure can achieve focused polarized light emission. Different angles result in different polarization angles, and the required angle can be set according to actual needs.

[0316] Adjacent prism stripes are connected by a connecting surface, and the angle between the connecting surface and the plane where the prism stripes are located is 10° to 80°. Because the prism stripes are inclined and the adjacent prism stripes do not share edges with each other, a connecting surface is required to connect the adjacent prism stripes. The reason why the angle between the connecting surface and the plane where the prism stripes are located is an acute angle is that if it is an obtuse angle, there will be a blank area without stripes in the top view, which is not conducive to improving the utilization rate of light.

[0317] In the vertical direction, the ends of the prism stripes in the length direction have the same height, that is, the prism stripes are not inclined from one end in the length direction to the other end, but from one end in the width direction of the prism stripes to the other end.

[0318] Each prism strip is provided with a plurality of arc-shaped arches parallel to each other, which are long strips, and the curvature of the cross section is 0.45-1.20.

[0319] The connecting surface is a smooth plane to simplify the processing procedure and reduce the processing cost.

[0320] Preferably, the top inner wall of the central accommodating cavity (310A) is flat, and a total reflection surface (310c) is provided on the outer side wall of the lighting portion surrounding the central accommodating cavity (310A).

[0321] In summary, the present invention can achieve polarization at a larger angle while obtaining a light spot by arranging a plurality of mutually parallel inclined prism strips on the light emitting surface (310f), thereby improving the utilization rate of light and making it possible for LED light-emitting equipment to achieve a good light distribution effect without adding an elevation angle, thus simplifying the structure and reducing costs.

[0322] When the present invention is used in LED lighting equipment, Fig.96 As shown, the circuit board (350) of the LED (340) is fixed to the bottom of the LED long afterglow composite light-emitting lens through a positioning structure, and the gap between the circuit board (350) and the LED long afterglow composite light-emitting lens is sealed with a packaging glue, and the LED is fixed in the air layer of the central accommodating cavity (310A), and then the bottom is sealed with a packaging glue; the light of the LED (340) is mainly divided into three paths, such as Fig.95As shown in the figure, the first path of light directly irradiates the lower part of the inner wall of the central accommodating cavity (310A), irradiates the total reflection surface (310c) after being refracted by the inner wall of the central accommodating cavity (310A), and after being reflected by the total reflection surface (310c), it is polarized and emitted from the light emitting surface (310f) of the lens; the second path of light directly irradiates the light incident surface (310a1) of the top wall of the central accommodating cavity (310A), and after being focused by the Fresnel focusing lens, it is directly emitted from the lens body. The third path of light directly irradiates the upper part of the inner wall of the central accommodating cavity (310A), irradiates the light coupling surface located above the total reflection surface (310c) and adjacent to it after being refracted by the inner wall of the central accommodating cavity (310A), and is transmitted to the long afterglow luminous molding (320) in the accommodating groove (310B) through the liquid or molten transparent light-guiding medium (330) and excites the long afterglow luminous molding (320) to emit light.

[0323] The LED long afterglow composite light-emitting lens with a TIR total reflection structure combined with a prism directional angle (deflected at a certain angle along the axial direction) output structure of the present invention has the functions of LED focusing and polarization, as well as long afterglow light-emitting function, and can meet the emphasis required for actual light emission by selectively allocating the light energy ratio of the excitation light and the output light; it can serve as a light distribution component or a light distribution assembly or a light-emitting component or a light-emitting assembly for making various light-emitting equipment, and can also be used as a local structure in combination with other optical components or light-emitting components to design and make various light-emitting devices, components or equipment, such as waterproof point light sources, module point light sources, light-emitting point light source assembly modules, point light source patterns, text or letter or symbol modules, multi-functional lamps, light-emitting signboards, outline lights or outline marks, floor lamps, etc., which have both conventional lighting uses and long afterglow light-emitting function, and have a wider range of applications.

[0324] Embodiment 4

[0325] Embodiment 4 of the present invention provides a waterproof point light source (or light-emitting lamp) with an LED long afterglow composite light-emitting lens. The lens of embodiment 1 can be used as needed to manufacture a waterproof point light source (or light-emitting lamp) with an LED long afterglow composite light-emitting lens with a focusing structure. The shape of the LED long afterglow composite light-emitting lens can be cylindrical, such as Figure 28-32 As shown, or flat round, as Figure 33-36 shown.

[0326] The circuit board (450) of the point light source LED (440) can be directly fixed to the bottom of the LED long afterglow composite light-emitting lens through a positioning buckle, and the gap between the circuit board (450) and the LED long afterglow composite light-emitting lens is sealed with a packaging glue, and the LED is fixed in the air layer of the central accommodating cavity (410A), and then sealed with a bottom shell or a bottom plate below the circuit board (450). The bottom shell can be transparent (PC, etc.) or non-transparent (ABS, etc.), and can be connected into one piece by secondary injection molding, or can be assembled twice after split molding (such as gluing it to the bottom of the lens with transparent glue), and its shape can be square (such as Figure 28-31 as shown) or round (as Figure 33-35 as shown) or rhombus or hexagon (as shown Fig.32 As shown in FIG. 1 , the extended portion may have screw holes to facilitate installation.

[0327] A commercially available conical TIR condensing lens can also be selected as a secondary lens, and the top surface of the lens is bonded to the inner top wall of the lamp housing (the surrounding edge of the lamp housing can be opaque) through a light-guiding adhesive, and an annular groove is formed between the TIR total reflection surface of the lens and the surrounding edge of the lamp housing, thereby forming a secondary combined lens body structure with an annular groove. After the lens body structure is inverted, a liquid mixed slurry of SrAl2O4 type long afterglow luminescent powder and transparent epoxy glue is poured into the annular groove at a certain height (generally close to the top light-emitting surface of the lens body structure) for leveling and curing, and an LED (440) with a circuit board (450) is fixed below the condensing lens through a positioning buckle, and then the bottom of the circuit board (450) is sealed with a packaging adhesive.

[0328] Furthermore, the entire annular receiving groove (410B) can be divided into two or more sections by transparent barriers, and the long afterglow luminous molding (420) is combined on the inner wall of each section.

[0329] Furthermore, the height of the top of the LED (440) from the top wall of the central accommodating cavity (410A) can be adjusted as needed to achieve a desired lighting effect.

[0330] Furthermore, the lens of the second embodiment can be used to make a waterproof point light source (or light-emitting lamp) with a divergent structure LED long afterglow composite light-emitting lens, such as Figures 83-87 As shown; or use the lens of Example 3 to make a waterproof point light source (or light-emitting lamp) with a LED long afterglow composite light-emitting lens with a side-emitting structure.

[0331] Furthermore, a non-rotationally symmetrical LED long afterglow composite light-emitting lens structure with a lateral emission function may be used, such as Fig.97As shown, the light-emitting portion of the light-distributing optical main body (4110) of the lens bulges upward into an oval convex surface, and is higher in the front and lower in the back, and symmetrical on the left and right (along the vertical plane passing through the central axis). A concave (upward concave) central accommodating cavity (410A) capable of allowing light from the light source to enter is provided at the rear position (eccentrically) at the bottom center of the light-distributing optical main body (4110). The central accommodating cavity (410A) is a non-rotationally symmetrical shape that is shallow in the front and deep in the back and symmetrical on the left and right. The top wall light-entry surface (410a1) is an arc surface, and its curvature gradually decreases from the back to the front. The top light-emitting surface (410f1) is an arc surface, and its curvature gradually increases from the back to the front. A shape with a wall thickness that gradually increases from the back to the front is formed between the top wall light-entry surface (410a1) and the top light-emitting surface (410f1), so as to facilitate emission to the front and side. An inwardly concave annular accommodation groove (410B) is provided around the central accommodation cavity (410A), and the accommodation groove (410B) is in the shape of a non-rotationally symmetrical annular shape that is larger at the front and smaller at the back and symmetrical left and right.

[0332] After inversion, a liquid mixed slurry of SrAl2O4 type long afterglow luminescent powder and transparent epoxy glue is poured into the annular receiving groove (410B) to a certain depth for leveling and curing, and the LED (440) with the circuit board (450) is fixed below the lens through a positioning buckle, so that the LED is located in the corresponding central receiving cavity (410A) and is slightly rearward (eccentrically arranged), and then the bottom of the circuit board (450) is sealed with packaging glue; it can be directly buried in the ground or fixed in the installation hole of a vehicle or facility through surface threads, and at this time, its light-emitting portion is arranged to protrude from the surface, so as to have a better lateral lighting effect.

[0333] like Fig.98 As shown, when the LED (440) emits light, the light is mainly divided into two paths. The first path of light is incident on the light incident surface (410a) forward, and after being refracted by the lens, most of the light is emitted forward along the side through the light emitting surface (410f); the second path of light is incident on the light incident surface (410a) backward, and most of the light is totally reflected on the light emitting surface (410f), and is incident on the long afterglow light-emitting molded body (420) through the light guide coupling surface (410e) and stimulates the long afterglow light-emitting molded body (420) to emit light; when the power is off, part of the light emitted by the long afterglow light-emitting molded body (420) in the accommodating groove (410B) can be emitted from the light emitting surface (410f).

[0334] The lens can make the proportion of light energy emitted by the LED toward the front and side larger. After the LED is turned off, the long afterglow luminous molding (420) is larger in the front and smaller in the back, and has a better forward afterglow luminous effect. It can be set as needed to meet the needs of different luminous emphasis, such as a better luminous effect facing vehicles or pedestrians.

[0335] Furthermore, it can also be packaged in a stainless steel shell or an aluminum shell, etc., which can be buried in the ground or fixed in the installation hole of a vehicle or facility through surface threads, such as Fig.86 , 87 shown.

[0336] The waterproof point light source containing the LED long afterglow composite light-emitting lens of this embodiment has both the conventional LED emission function and the conventional lighting purpose, and the long afterglow light-emitting function, and can meet the focus required for actual light emission by selectively allocating the light energy ratio of the excitation light and the emission light; it can be used alone or in combination, such as connecting multiple waterproof point light sources into a string with a wire to be used as a light strip, such as Fig.30 As shown; it can also be used as a light-emitting component to make various light-emitting devices, components or equipment.
