New Description: [New Technology Field] This creation is related to the technical field of optical lenses. In particular, it relates to an LED optical lens that increases the angle of irradiation to change the illumination of the original LED by three optical principles. angle. [Prior Art] Light Emitting Diode (LED) has a wide range of characteristics such as low power consumption, high efficiency, and long life, and is widely used in various backlights or bulb tubes. However, the angle of illumination of LEDs is typically only about 120. Therefore, the illumination range is limited' and since the illuminating light of the LED is generally concentrated at the center, the brightness difference between the center and the periphery is so great that it cannot provide a uniform illumination effect. Thus, various types of LED illumination devices using LEDs as light sources will be limited by the original illumination angle of the LED light source and the distribution of the original light to form a small illumination range and poor light uniformity, which is difficult to meet user requirements. In view of this, the LED illumination device is configured with an optical lens to improve the light path direction of the light source emitted by the coffee source by using the secondary optical principle of the optical lens, that is, the illumination of the needle coffee source, the illumination angle, and the illumination light are improved. The light-appearance layout with better applicability is provided, and the optimal illumination state is provided in various different ways. ', under the piece, the trend of miniaturization of the device - prevention - > points ~ ring, or in order to meet the high illuminating illuminance and high illumination range, etc. „ ^ ^ ^ ' may be equipped with multiple LEDs, If this is the case, the lens in the LED makeup device will be configured to limit the configuration of the optical lens. The optical effect (the secondary optical effect and the appearance volume of the lens) will not provide the best illumination. 3 M441834 Status In this regard, 'how to further utilize the optical function of the optical lens, the subject of goodness. The principle of reflection of three optics improves the related content of the practitioners in this field. I want to change the new content of the I.] The purpose of the invention is to provide an LED lens for improving the irradiation angle, in order to utilize the principle of reflection or refraction of three opticals to change the direction of the light-receiving direction of the LPn > LED, and to increase the illumination angle' According to the purpose of this creation, the LED optical lens system of the irradiation angle of the 兮 s s W is assembled in an LED *, , e ^ ^ ^ LliU 九源' is characterized by: the LED optical lens The first medium body is formed with a closed type of at least one accommodating chamber, and the first "quality system is placed in the first medium body; In the accommodating chamber, the second medium system is an opaque material. In the middle, the accommodating chamber is completely filled by the second medium body, and the valley chamber is opposite to the central axis of the first medium body. It is set in a wraparound manner. And 'in view of the production cost and product quality, the first medium is formed integrally, or the first medium system is constructed by a 仵 斤 _ _ 〇 gt; In order to increase the uniformity of the emitted light of the LED light source through the #μ2 to the lens, the side surface of the first medium body:: a side light uniform means for the side emitted by the LED light source. After the uniform means, the illuminating area of the one side target is _ _ , ", y, y knives, and the top surface of the first medium body is provided with a top light q - part light hg hand slave, for The light emitted by the LED light source passes through the top and is evenly pitched. The standard illumination area is uniform illumination. M441834 light uniform means back stitch-shoot distribution. And, the top target illumination area is evenly illuminated, and the surface of the T member 201 is respectively provided with a convex leaf... LED first and second After the multiple stages of the scales, the light emitted by the side/original light is uniformly distributed by the side of the light, and the area of the heart is uniformly distributed. It is worth noting that the 哕笪... The # # # 23 is planar and surrounds each other and is disposed on the side surface of the first member 200 to form a layer of leaf loops from the side surface of the first member 201. y people can also be described? In conjunction with the actual light shape requirement, the second medium body 21 is second: number: use type. As shown in FIG. 6 , which is a three-dimensional appearance of the second embodiment of the present invention, the first two-mass body 20 is provided with three housings in an arc-shaped segment space structure. The accommodating chambers are spaced apart from each other and disposed around a central axis of the first body 20, and the second accommodating body 21 is completely filled in the accommodating chambers. Thus, the LED light source handles the light, and the light is irradiated to the LED optically through the ground; the top of the cable 2 is transported, and a part of the light is blocked by the second medium body 21 and blocked. Change the light path to the universal direction. Alternatively, as shown in Figs. 7 and 8, respectively, it is a perspective view of a further embodiment of the second preferred embodiment of the present invention.视 视 视 视 视 视 视 视 视 视 视 视 视 视 视 第 第 第 第 第 第 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 介质 视 视 视 视The farther the bottom of the optical lens 2 is, the smaller the frame space #^,,» is. Thus, if the container closer to the bottom of the LED optical lens 2 is the first housing chamber and the other is the second housing chamber, part of the light emitted by the LED light source room will be affected by the The first accommodating chamber blocks reflection, and part of the light enters _ ^ ·· _ .......................... - v is reflected in the M441834 Two accommodation rooms. In this way, the second medium body 21 can be further strengthened by the stacked second medium body 21 to effectively increase the illumination angle and the illumination range, and the second accommodation chamber can completely fill the second medium body 21, thereby increasing The amount of reflected light. Incidentally, the present invention utilizes the opaque second medium body 21 to reflect the light emitted by the LED light source to form a wider illumination angle. Therefore, the reflection principle is more as shown in FIG. It is a schematic cross-sectional view of another embodiment of the second preferred embodiment of the present invention, such that the two second dielectric bodies 21 are arranged in a funnel-like structure, and the tip ends thereof face the LED optical lens! The farther the second medium body 21 is from the bottom of the LED optical lens 1, the larger the funnel-like structure.
