Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp holders, in particular to a high-light-efficiency LED lamp holder with an eye-protecting natural light color. Background Art

[0002] At present, the light-emitting principle of LED is to use the light-emitting chip and the corresponding phosphor to realize the light-emitting diode. This light-emitting method usually adopts two implementation methods. One method is that the blue light LED light-emitting diode excites the yellow phosphor to produce white light. The other method is that the ultraviolet LED excites the RGB three-wavelength phosphor to produce white light. Conventional backlight products use a single blue light chip with yellow phosphor to excite white light. This method has low light efficiency, and the brightness of a single lamp bead cannot meet the requirements. The color of the lamp bead after assembly is unnatural, and long-term viewing after lighting is harmful to the human eye. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a high-efficiency LED lamp holder with eye-protecting natural light color, which solves the technical problems that the light efficiency of a single blue light chip is low, the brightness cannot meet the requirements, the color is unnatural after assembly, and long-term viewing causes certain damage to the eyes. It achieves the purpose of achieving high light efficiency, high color rendering index, light spectrum closer to natural light and protecting the eyes by using high and low wavelength blue light chips with fluorescent silicone of different wavelengths.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a high-efficiency LED lamp holder with eye-protecting natural light color, comprising a base plate, and a light mixing mechanism for further scattering the light is fixedly connected to the inner side of the base plate.

[0005] Preferably, the light mixing mechanism includes a bottom plate installed in the base plate, the top of the bottom plate is fixedly connected to a refractive prism for scattering light, the top of the refractive prism is fixedly connected to a mixing lens for preventing the fluorescent silicone from falling off, and the bottom surface of the bottom plate is provided with several heat dissipation tooth plates.

[0006] Preferably, conductive welding points are provided on both sides of the top surface of the base plate, support frame mounting holes are provided around the bottom surface of the base plate, and a chamfered slope is provided on the top of the inner wall of the base plate for converging the fluorescent silica gel to the top surface of the bottom plate.

[0007] Preferably, a supporting lens is fixedly connected to the top surface of the light mixing mechanism, a light source chip is fixedly connected to the top surface of the light mixing mechanism, and a transparent protective plate for protecting the light source chip is fixedly connected to the top surface of the supporting lens.

[0008] Preferably, the refractive prism is a triangular prism that scatters light, the light-mixing lens is in the shape of a convex lens, and the plurality of heat dissipation tooth plates are all serrated and equidistantly distributed.

[0009] Preferably, the conductive welding points are arranged in the middle positions of both sides of the base plate.

[0010] Preferably, the supporting lens is a convex lens that is thick in the middle and thin at both sides and has smooth edges and corners.

[0011] By means of the above technical solution, the present invention provides a high-light-efficiency LED lamp holder with an eye-protecting natural light color, which has at least the following beneficial effects:

[0012] 1. The utility model refracts two wavelengths of blue light through a light mixing mechanism. At the same time, the blue light excites the fluorescent silicone to generate light of other wavelengths which is also refracted.

DETAILED DESCRIPTION

[0023] To make the above-mentioned objectives, features, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. This will enable a full understanding of how the present invention applies technical means to solve technical problems and achieve technical effects, and to implement the invention accordingly.

[0024] Since the light efficiency of a single blue light chip is low, the brightness cannot meet the requirements, the color is unnatural after assembly, and long-term viewing may cause damage to the eyes. Please refer to Figure 1 - Figure 5 , this embodiment provides a high-efficiency LED lamp holder with eye-protecting natural light color, which can achieve high luminous efficiency and high color rendering index by adopting high and low wavelength blue light chips with fluorescent silicone of different wavelengths. The spectrum is closer to natural light and can protect the eyes. The inner side of the base plate 1 of the lamp holder is fixedly connected to a mixing mechanism 4 for further scattering the light. The mixing mechanism 4 includes a bottom plate 401 installed in the base plate 1, and a refractive prism 402 for scattering the light is fixedly connected to the top of the bottom plate 401. A mixing lens 403 is fixedly connected to the top of the refractive prism 402 to prevent the fluorescent silicone from falling off. A plurality of heat dissipation tooth plates 404 are provided on the bottom surface of the bottom plate 401. The refractive prism 402 is a triangular prism for scattering light, and the mixing lens 403 is a convex lens. The multiple heat dissipation tooth plates 404 are all serrated and equidistantly distributed.

[0025] It should be noted that fluorescent silicone is first made by mixing phosphors that can excite light of different wavelengths with silicone. Two blue light LED chips with different wavelengths are set inside the lamp holder. The crystal fixing method uses a series method. By optimizing the matching method between the chip and the phosphor, the luminous efficiency of the same material is improved, and the spectrum is closer to natural light, which is more conducive to protecting the human eyes. The optimization method is specifically to use two blue light chips with a wavelength of 420nm-480nm, and match the first phosphor with a peak wavelength of 480nm-520nm, the second phosphor with a peak wavelength of 530nm-540nm, the third phosphor with a peak wavelength of 640nm-660nm, and the fourth phosphor with a peak wavelength of 680nm-700nm. The above phosphors are evenly mixed with fluorescent silicone and covered on the two blue light chips. The mixed light excited by this combination is closer to natural light, the light is softer, and the effect of protecting the eyes is achieved.

[0026] After the above fluorescent silicone material is covered on the blue light chip, the fluorescent silicone is completely covered. At the same time, the fluorescent silicone also covers the bottom plate 401 and the refractive prism 402, and the liquid level reaches the bottom surface of the mixing lens 403. The refractive prism 402 can refract the two wavelengths of blue light twice. At the same time, the other wavelengths of light generated by the blue light stimulating the fluorescent silicone are also refracted twice. The triangular prism has different refractive angles for light of different wavelengths, thereby fully mixing the light of different wavelengths, making the mixed light more full and natural, and the illumination angle of the refracted light becomes larger, and the illumination range is wider. Combined with the convex lens effect of the mixing lens 403, the light can obtain a larger illumination range at a distance. At the same time, the bottom area of ​​the mixing lens 403 is larger than the cross-sectional area of ​​the refractive prism 402, so that the hardened fluorescent silicone can be fixed by the mixing lens 403, avoiding the situation that the fluorescent silicone will fall off, and prevent the fluorescent silicone from falling off after a period of use, or passively separating due to vibration. Since two blue light chips are used for light emission, the heat dissipation of the lamp bead itself is a major problem, so the bottom heat dissipation tooth plate 404 assists in heat dissipation.

[0027] In an optional embodiment, conductive welding points 101 are provided on both sides of the top surface of the base plate 1, support frame mounting holes 102 are provided on all four sides of the bottom surface of the base plate 1, and a chamfered inclined surface is provided on the top of the inner wall of the base plate 1 to make the fluorescent silicone converge to the top surface of the bottom plate 401. The conductive welding point 101 is provided in the middle position of both sides of the base plate 1.

[0028] It should be noted that during the installation process, the lamp holder is welded through the conductive welding point 101 to facilitate the conductive connection of the lamp bead. The conductive welding point is made of commonly used metal materials, and the lamp bead is supported by the support frame mounting hole 102 to facilitate the fixation of the lamp bead. The use of the hole structure can enable the support frame to better support and withstand more force. At the same time, the support frame can provide a certain space for the bottom of the lamp bead, which is convenient for the top heat dissipation tooth plate 404 to dissipate heat from the lamp bead and improve the heat dissipation efficiency.

[0029] In an optional embodiment, the top surface of the light mixing mechanism 4 is fixedly connected to a supporting lens 3, the top surface of the light mixing mechanism 4 is fixedly connected to a light source chip 5, the top surface of the supporting lens 3 is fixedly connected to a transparent protective plate 2 for protecting the light source chip 5, and the supporting lens 3 is a convex lens that is thick in the middle and thin on both sides with rounded edges and corners.

[0030] It should be noted that the support lens 3 is in the central position, which can refract the light on both sides again. At the same time, the support lens 3 and the transparent protective plate 2 are fixedly connected, which can also protect the fluorescent silicone from falling off and increase the service life of the lamp beads. The transparent protective plate 2 covers the top, which can protect the inner structure from being affected by dust or vibration, and avoid heavy objects directly pressing on the internal structure from the top.

[0031] Please refer to Figure 6 The blue LED chip excites the fluorescent silicone to produce light of different colors, thus forming mixed-color light. This light is not mixed sufficiently after the fluorescent silicone emits light, and the color mixing effect is unsatisfactory, which is somewhat different from natural light. In the present invention, the light around the refractive prism 402 is incident from approximately three angles. As can be seen from the figure, the secondary refraction of the triangular prism structure can separate the mixed-color light. The figure only shows two different colors of light after separation. In practice, it appears as a variety of colors of light according to the wavelength of the phosphor, and is mixed again after refraction. Compared with the linear light mixing in the prior art, the light can be more fully mixed after refraction separation, which is similar to the principle of diffuse reflection, making the optical fiber closer to natural light and not harmful to the eyes.

[0032] Please refer to Figure 7 The present invention can also change the exit angle of the outgoing light through the mixing lens 403 to obtain a larger illumination area. According to the light emitted by the light source point, the dotted line represents the original light without improvement, and the solid line represents the improved light. It can be seen from the figure that the improved light is refracted by the refractive prism 402 and the mixing lens 403, and its deflection angle is significantly increased, thereby increasing the range of distant illumination and further obtaining a larger illumination area. Therefore, the present invention can use the refractive prism 402 and the mixing lens 403 to make the light mix more evenly by refraction, which is close to natural light and protects the eyes, increases the illumination area, and enables a single lamp bead to illuminate a larger range.

Reference can be made to the same or similar parts between the embodiments.
