Current solutions cannot meet all these demands. In particular, high-power LED chips have many technical limitations such as heat dissipation, efficiency, and cost, which limits the total luminous flux and power of lighting fixtures.

[0022] This utility model proposes a light-emitting device, the structural schematic diagram of which is shown below. Figure 1a As shown, the light-emitting device includes an LED chip array 101, which comprises multiple LED chips, such as LED chip 101a. It also includes a light-collecting device array 102, which comprises multiple light-collecting devices, such as light-collecting device 102a. Each LED chip corresponds to one light-collecting device; for example, LED chip 101a corresponds to light-collecting device 102a. The light-collecting device 102a collects the light emitted by the corresponding LED chip 101a, adjusts its angle, and then emits it. The light-emitting device also includes a concave lens 103, which receives the light emitted from the light-collecting device array 102, adjusts its angle, and then emits it. The emission angle of the light emitted from the light-collecting device array 102 is smaller than that of the LED chip array 101, and the emission angle of the light emitted from the concave lens 103 is larger than that of the light emitted from the light-collecting device array 102.

[0023] Specifically, such as Figure 1bAs shown in the top view, multiple LED chips form an LED chip array 101. In this embodiment, there are 7 LED chips and 7 light collection devices, corresponding one-to-one. The light emitted by each LED chip is collected by the light collection device and then emitted. The light emitted by the LED chip is close to Lambertian emission (emission angle 180 degrees). Such large-angle emission must be collected by the light collection device to compress the angle before it can be fully utilized. In this embodiment, the light collection device array 102 includes 7 light collection devices. For example, each light collection device includes two convex lenses (which may be plano-convex, biconvex, or double-convex) placed one after the other along the light path. These lenses are used to compress the large-angle emission of the corresponding LED chip. The emission angle of the light emitted from the light collection device array 102 is smaller than the emission angle of the LED chip array 101. In practice, various other methods such as reflectors and TIR lenses can also be used to implement the light collection device, which will not be elaborated or limited here. The light-emitting device also includes a concave lens 103. The function of the concave lens 103 is to diverge the incident light, so that the emission angle of the light emitted from the concave lens is greater than the emission angle of the light emitted from the light-collecting array. For example, ray 121 in the figure is emitted from the LED chip 101a at an angle of approximately 45 degrees. After passing through the light-collecting device 102a, it is basically collimated and then diverged again by the concave lens 103 to an angle of approximately 30 degrees. It is worth noting that the emission angle mentioned here does not refer to a single ray (ray 121 is only an example of one ray in the overall beam), but rather to the range of emission angles of all light rays. That is, the overall emission angle of the light emitted from the light-collecting array 102 is smaller than the overall emission angle of the LED chip array 101, and the overall emission angle of the light emitted from the concave lens 103 is greater than the overall emission angle of the light emitted from the light-collecting array 102. The emission angles in this invention all refer to the full emission angle. For example, the overall light emission angle of the LED chip array 101 is 130 degrees. After passing through the light collection device array, the overall light emission angle becomes 20 degrees. After passing through the concave lens 103, the overall light emission angle becomes 60 degrees.

[0024] In this embodiment, the light angle is first compressed using the light-collecting device array 102, and then the light angle is diverged using the concave lens 103. This seemingly contradictory optical treatment reveals the inventor's ingenuity. The light emitted by each LED chip in the LED chip array 101 is collected and emitted by the light-collecting device array. At the rear end of the optical path of the light-collecting device array, a complete beam of light is formed, meaning the light emitted by each LED chip is pieced together, which can be equivalent to the light emitted by a single large LED chip. After passing through the concave lens 103, a unified divergent light is formed, which is also equivalent to the light emitted by a single large LED chip. Therefore, after the angle compression by the light-collecting device array 102 and the angle divergence by the concave lens 103, the LED chip array 101 is optically equivalent to a single large LED chip. This has three advantages. First, compared to a large LED, multiple small LED chips are easier to dissipate heat, thus making multiple small LEDs more efficient. Second, large LEDs have a power limit; if they are too large, the manufacturing yield and cost will be too high. However, the method of using multiple small LED chips in this embodiment can increase the power almost infinitely by increasing the number of LED chips. Third, large LED chips are driven by a "low voltage, high current" method, while multiple LED chips in this embodiment can be driven by a flexible series-parallel connection, resulting in lower driver chip costs.

[0025] In summary, in this embodiment, the light emitted by the LED chip array 101 is collected and its angle is adjusted by the light collection device array 102, and then the light beam is diverged by the concave lens 103, so that the multiple LED chips in the LED chip array are optically equivalent to a large LED chip, thereby improving the efficiency of the light-emitting device and the upper limit of power expansion.

[0026] In this embodiment, as Figure 1b As shown, the light collection devices are arranged closely together, which reduces the size of the light-emitting device and helps to increase the energy density of the light, thereby increasing the brightness of the emitted light.

[0027] In this embodiment, the concave lens 103 is a plano-concave lens, with its planar surface facing the light-collecting device array 102. This is not mandatory; in practice, a double-concave or even convex-concave lens surface can be used depending on the design, as long as the effect of increasing the emission angle is achieved. Furthermore, the concave surface of the concave lens does not necessarily have to be continuous. For example, a Fresnel lens with a sheet-like shape (its surface includes multiple concave surfaces arranged in a ring array) or a partitioned concave surface shape can be used, again as long as the effect of increasing the emission angle is achieved. Therefore, in this invention, "concave lens" refers to an optical element that can diverge the emission angle through refraction, and does not limit the specific surface shape and form of the optical device.

[0028] In practical applications, there are situations where both illumination distance and illumination range need to be considered. Based on the above embodiments, the inventors further conceived of using a laser device to improve the brightness of the light-emitting device, while also integrating the laser device internally into the light-emitting device. A schematic diagram of the specific light-emitting device is shown below. Figure 2a As shown, Figure 2b This is a perspective top view of this embodiment.

[0029] This light-emitting device also includes a laser device, which comprises a laser source 204, a phosphor conversion material 205, and a collimating optical system 207. The laser source 204 emits a laser 222 to excite the phosphor conversion material 205 to emit a received laser 223. The received laser 223 is incident on the collimating optical system 207 and collimated before exiting onto the concave lens 203. The light emitted by the LED chip array (e.g., including LED chips 201a and 201b) is collected and compressed at an angle (e.g., light beam 221) by the light-collecting device array (e.g., including light-collecting devices 202a and 202b), and can be combined with the collimated received laser (e.g., light beam 223) emitted by the laser device into a single beam. After passing through the concave lens 203, the beam diverges and is equivalent to the light emitted by a unified light source. This equivalent light source, based on the equivalent large LED chip of the LED chip array, has a very high central light intensity and a long illumination distance, which is contributed by the laser device, thus balancing the illumination range and illumination distance.

[0030] In this embodiment, preferably, a metal substrate 209 is also included, on which the LED chip array and the laser device are fixedly mounted. In this way, the metal substrate can simultaneously heat the laser device and the LED chip array. This heat dissipation structure is the simplest and the laser device can be integrated into the interior of the entire light-emitting device, resulting in the most compact structure.

[0031] In this embodiment, preferably, multiple LED chips in the LED chip array are arranged around the laser device, such as... Figure 2b As shown. With Figure 2bUnlike the previous example, in this embodiment, the output aperture of the collimating optical system 207 is larger than that of the light-collecting devices (e.g., 201a and 201b). This has the advantage of achieving higher brightness with a larger aperture. Therefore, increasing the output aperture of the collimating optical system 207 used in the laser device can further enhance the central brightness. Of course, the aperture of the collimating optical system 207 does not necessarily have to be larger than that of the light-collecting device; this is merely a design approach to enhance the central light intensity. In reality, the aperture of the collimating optical system 207 can be equal to or even smaller than that of the light-collecting device. In this embodiment, because the output aperture of the collimating optical system 207 is larger than that of the light-collecting device, more LED chips can be arranged around the laser device, for example, eight in this embodiment. It is understood that more or fewer LED chips can be arranged according to actual design needs. In this embodiment, placing the laser device at the center of the system while arranging the LED chip array and the light-collecting device array around the laser device is merely a preferred design. This maximizes the high light intensity of the laser device while simplifying the optical design. In fact, the laser device can also be placed on the side of the light-emitting device, that is, the LED chip array is no longer placed around the laser device. In this case, although the light emitted by the laser device is not located in the center of the concave lens, the important thing here is not the surface distribution but the angular distribution. Therefore, in the back-end optical processing, the light emitted by the laser device is still located in the center of the light formed by the LED chip array, that is, it can still play the role of enhancing the central light intensity.

[0032] exist Figure 2a In the illustrated embodiment, the inventors mentioned that a larger light-emitting aperture can improve brightness. Using this idea, even without a laser device, it is possible to increase the central light intensity to some extent by using only an LED chip array. In another embodiment, its structural schematic diagram is shown below. Figure 3As shown, the light collection device array includes at least one first light collection device 302b, whose light-emitting aperture is larger than that of the other light collection devices 302a. In this embodiment, the LED chip array 301 includes multiple LED chips (e.g., LED chips 301a and 301b), and the light collection device array 302 includes multiple light collection devices (e.g., light collection devices 302a and 302b). Light emitted from the light collection device array 302 is incident on the concave lens 303 and then diverged. Because the light-emitting aperture of the first light collection device 302b is larger than that of the other light collection devices 302a, the light 322 emitted by the LED chip 301b corresponding to the first light collection device 302b is more concentrated at the center position in the equivalent large LED chip, resulting in higher brightness. Of course, LED chips with higher light density can also be used for LED chip 301b to further improve the central light intensity. Thus, in this embodiment, an application scenario that balances illumination distance and illumination range can be achieved at low cost.

[0033] In this embodiment, preferably, a scattering device 308 is also included at the rear end of the optical path of the light collecting device. The scattering device can be a scattering sheet, an optical device with a microstructure on its surface, or a microstructure on the surface of a concave lens. Its function is to scatter the incident light, thereby shielding the non-uniformity of the LED chip's light-emitting surface. Preferably, the first light collecting device 302b is surrounded by other light collecting devices. This has the advantage of a simple structural design, but regardless of whether the first light collecting device 302b is located near the center line of the system, it does not affect its technical effect of enhancing the central light intensity.

[0034] Inventors in practice Figure 3 It was found during the implementation of the example shown that Figure 3 The illustrated embodiment simplifies the system, making it more compact and cost-effective by combining the first light-collecting device with the concave lens. This results in a new structure and embodiment, the structural schematic of which is shown below. Figure 4 As shown. In Figure 4The illustrated light-emitting device includes an LED chip array comprising multiple LED chips (e.g., LED chip 401a). It also includes a light-collecting device array comprising multiple light-collecting devices (e.g., light-collecting device 402a), with each LED chip corresponding to one light-collecting device. The light-collecting device collects the light emitted by the corresponding LED chip and adjusts its angle before emission. A first light source 404 is also included, with the LED chip array arranged around it. An adjustment lens 403 is also included, comprising an inner region 403a located in the center and an outer region 403b surrounding the inner region. Light emitted from the first light source 404 is incident on the inner region 403a of the adjustment lens and is adjusted in angle by the inner region 403a before emission; light emitted from the light-collecting device array is incident on the outer region 403b of the adjustment lens and is adjusted in angle before emission. Among them, the light emission angle of the light emitted from the light collection device array is smaller than that of the LED chip array; the light emission angle of the light emitted from the outer region 403b of the adjustment lens is larger than that of the light emitted from the light collection device array; and the light emission angle of the light emitted from the inner region 403a of the adjustment lens is smaller than that of the first light source 404.

[0035] The LED chip array is arranged around the first light source 404, that is, located on the periphery of the first light source. Taking the light-emitting path (ray 421) of the LED chip 401a in the LED chip array as an example, the light emitted by the LED chip 401a, after being collected and angularly compressed by the light-collecting device 402a, is incident on the outer region 403b of the adjusting lens 403. This outer region 403b is equivalent to... Figure 3 In the illustrated embodiment, the concave lens serves to diverge the incident light. The emission angle of the light emitted from the light-collecting device array is smaller than that of the LED chip array, while the emission angle of the light emitted from the outer region 403b of the adjusting lens is larger than that of the light emitted from the light-collecting device array. The working principle of the light emitted by this part of the LED chip array is the same as in the aforementioned embodiment. The working principle of the first light source 404 will be explained in detail below.

[0036] In this embodiment, the first light source 404 is also an LED chip, but we consider it as a separate light source independent of the LED chip array. The large-angle light emitted by the first light source 404 is directly collected and compressed by the inner region 403a of the adjustment lens 403 before being emitted. The emission angle of the light emitted from the inner region 403a of the adjustment lens is smaller than that of the first light source 404. Since the inner region 403a of the adjustment lens is equivalent to a convex lens, the angle of the incident light can be compressed. At the same time, since the curvature of a convex lens is limited, the light 422 emitted by the first light source 404 cannot be completely collimated. The light 422 emitted from the inner region 403a of the adjustment lens is still divergent, which allows it to diverge together with the light 421 emitted from the outer region 403b of the adjustment lens, thereby achieving the purpose of the present invention.

[0037] Therefore, the light emitted by the LED chip array is collected and compressed at an angle by the light collection device array, and then incident on the outer area of ​​the adjustment lens to form divergent light. At the same time, the light emitted by the first light source is collected and compressed at an angle by the inner area of ​​the adjustment lens and then directly forms divergent light. In this way, the divergent light emitted from the inner and outer areas of the adjustment lens can be unified to form an overall divergent light emission.

[0038] In this embodiment, preferably, at least one surface of the outer region 403b of the adjustment lens has a microstructure 408. The microstructure 408 is used to scatter the light emitted by the LED chip array, thereby eliminating the non-uniformity of the LED chip light-emitting surface. Specifically, as an example, in this embodiment, the microstructure 408 is located on the side of the outer region 403b of the adjustment lens that is opposite to the LED chip array.

[0039] As mentioned earlier, in order to enhance the central light intensity, the inner aperture of the adjusting lens can be set to be relatively large, so that the emission of the first light source 404 plays a role in enhancing the central light intensity in the neat beam. Preferably, the aperture of the inner region 403a of the adjusting lens is greater than or equal to 0.4 times the aperture of the adjusting lens. According to the inventors' practice, this can effectively enhance the central light intensity of the emitted light.

[0040] As an example, the first light source includes an LED device comprising an LED light source and a second convex lens. Light emitted from the LED light source is collected by the second convex lens and then emitted, incident on the inner region of the adjusting lens. Since the LED light source emits light at a large angle (Lambertian emission), in some practical applications, using only the inner region 403a of the adjusting lens is insufficient for collecting and compressing the angle of the LED light emission. The use of the second convex lens solves this problem; that is, the combined effect of the second convex lens and the inner region 403a of the adjusting lens can achieve ideal control of the emitted laser light. Furthermore, the second convex lens is integrally formed with at least part of the light collecting device array, which further reduces costs.

[0041] In another embodiment, the first light source includes a laser device, as shown in the schematic diagram of this embodiment. Figure 5 As shown. The laser device includes a laser source 504 and a fluorescence conversion material 505. The laser source 504 emits an excitation 522, which in turn excites the fluorescence conversion material 505 to emit a received laser 523. This received laser 523 is incident on the inner region 503a of the adjustment lens 503. Figure 2a Compared to the embodiments shown, this embodiment is smaller in height and reduces one lens in the collimating optical system, thus reducing assembly difficulty and cost.

[0042] In this embodiment, the laser 523 does not need to be collimated by a collimating optical system and then diverged by a concave lens. Instead, the inner region 503a of the adjustment lens is used to collect and compress the laser 523. The light after angle compression is still divergent. In this way, it can be combined with the divergent light 521 emitted from the LED chip array (in the example, one of the LED chips 501a) after passing through the light collection device array (in the example, one of the light collection devices 502a) and then through the outer region 503b of the adjustment lens to form a single beam of divergent light emission.

[0043] In this embodiment, preferably, the laser device further includes a first convex lens 507, which collects the laser 523 before it is emitted and incident on the inner region 503a of the adjusting lens. Since the fluorescence conversion material 505 emits light at a large angle (Lambertian emission), in some practical applications, using only the inner region 503a of the adjusting lens is insufficient for collecting and compressing the angle of the laser. The use of the first convex lens 507 solves this problem; that is, the combined effect of the first convex lens 507 and the inner region 503a of the adjusting lens can achieve ideal control of the laser.

[0044] In this embodiment, a metal substrate is also included, on which the LED chip array and laser device are fixedly mounted. This simplifies the system structure. Preferably, the surface of the inner region 503a of the adjusting lens is smooth, so that the light emission 523 of the laser device can achieve maximum light intensity.

[0045] In this embodiment, preferably, at least one surface of the outer region 503b of the adjustment lens has a microstructure 508. The microstructure 508 is used to scatter the light emitted by the LED chip array, thereby eliminating the non-uniformity of the LED chip light-emitting surface. Specifically, as an example, in this embodiment, the microstructure 508 is located on the side of the outer region 503b of the adjustment lens facing the LED chip array. Of course, in practical applications, the microstructure may not be necessary, because the uniformity of the LED chip surface itself is constantly improving, and the stacking of multiple LED chips can also improve the uniformity to some extent.

[0046] This utility model also proposes a lighting device, the structural schematic diagram of which is shown below. Figure 6 As shown. This lighting device uses, as Figure 5 The light-emitting device shown also includes a convex lens 610, which receives the emitted light from the adjusting lens 603 and adjusts its angle before emitting it. The light-emitting device in this embodiment of the lighting device is... Figure 5 The light-emitting device shown differs slightly in that, in this embodiment, the inner region 603a of the adjusting lens 603 is planar and does not adjust the angle of the light. That is, the laser light emitted from the fluorescent conversion material is only collected and angularly compressed by the first convex lens 607, and not by the inner region 603a of the adjusting lens 603. This still allows for the emission of divergent light. Therefore, in this embodiment, the emission angle of the light emitted from the inner region of the adjusting lens is equal to the emission angle of the first light source. Thus, in this invention, with proper design, it is possible for the emission angle of the light emitted from the inner region of the adjusting lens to be less than or equal to the emission angle of the first light source. Since the light emitted from the adjusting lens 603 is generally divergent, the distance between the convex lens 610 and the adjusting lens 603 can be relatively short, resulting in a more compact system size.

[0047] In this invention, a convex lens refers to a positive lens that converges light. It does not limit the shape of the lens. For example, plano-convex, concave-convex, biconvex, Fresnel lenses, or partitioned lenses all fall within the definition of a convex lens and are protected within the scope of protection of convex lenses.

[0048] It should be noted that the distinguishing technical features between the various embodiments of this utility model are not limited to their respective embodiments, but can be applied to all embodiments. It is impossible to list all possible combinations in the description of this utility model. Therefore, the implementation principle and beneficial effects of each technical feature are explained by way of example. When applied to other embodiments, those skilled in the art will use its implementation principle to achieve the beneficial effects.
