New description: [New technical field] This creation is about a kind of lens, especially a light source lens structure suitable for the light-emitting diode to achieve uniform light and increase the light-emitting range. [Prior Art] With the advancement of technology and the concept of energy conservation and environmental protection, the global energy conservation issue will be fermented and the policies of governments will continue to ban incandescent bulbs in the future. The most ideal way is to use LEDs. As a light source, the advantages of high efficiency, energy saving and dimming of the light-emitting diode (LED) have gradually formed a trend in the lighting market, and its application in street lamps, lamp lights, outdoor lighting, and situation lighting has attracted worldwide attention. Focus. However, at present, many light-emitting diodes (LEDs) are used as illumination devices, and the light-emitting diode light source is direct light, and the light source generated by the entire light-emitting diode can only be irradiated toward the opposite region, and The illumination effect is not generated on the peripheral region of the side of the light-emitting diode, and the generated light causes a visually uncomfortable feeling in the visual field of the human eye or a glare phenomenon causing a decrease in vision. Glare is one of the factors affecting the lighting quality of lamps. The definition of glare is that the peak intensity of light in traditional lighting devices is about 60 degrees from the vertical direction, which will directly form a direct glare into the line of sight of the human eye. Feeling tired and laboring increases the risk. Moreover, the distribution of the conventional light source on the ground is mostly a circular or elliptical symmetrical shape. If a large amount of light is emitted on a large area of the ground, the light is emitted outside the ground, in the conventional light-emitting diode. The use of lenses for the original 3 illumination angle or projection range is not properly designed and planned, resulting in great limitations in use, even if the power of the LED or increase the number of LEDs can not be solved The problem of insufficient illumination angle and glare of the light-emitting diode light source device is how to improve the light-emitting angle and glare of the light-emitting diode. The reason is that the creator has in view of the lack of light-emitting angle of the existing light-emitting diodes, and has been assisted by many years of manufacturing and design experience and knowledge in related fields, and has been ingeniously focused on the light-emitting two. The development and improvement of the polar lens structure is expected to achieve its higher practical efficiency. [New content] In view of this, this creation is intended to provide a lens suitable for a light-emitting diode to increase the light-emitting range as its main purpose. The purpose of 吝2 is to make the overall light source of the illuminating unit transmit through the lens structure to produce a uniform (four) brightness effect and prevent glare.

The convex curved surface is disposed on the outer surface 16 of the body, and the condensed concave portion 11 is disposed, and the obliquely widened portion 13 is disposed at a peripheral edge of the body. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the light-emitting unit 20, the light of the light-emitting unit 20 is concentrated by the condensing concave portion, and is refracted through the concave curved surface to transmit the light, and a part of the angle of the light source is projected to the astigmatism convex portion 12, The structure of the convex curved surface is refracted to scatter, and a part of the angle of the light source is projected to the oblique wide-angle portion 13 , and the angle structure of the oblique surface is refracted, so that the light source is evenly lighted and the light is increased. range. Furthermore, as shown in the fourth figure, the present invention uses different reflective structures to reflect in the 5 M411533 line, and the light field distribution is achieved; wherein the light-emitting unit 20 first collects light through the condensing concave portion U and reveals the plural The light is transmitted through the astigmatism convex portion 12 and the oblique wide angle portion 13 respectively, and is respectively projected on the convex curved surface and the oblique cut surface, and is refracted by different angles, and the light can be angularly shifted. Out, this creation uses different positions and different structures, and the refracted light sources are respectively projected in different directions, and the light source will not simply project through the single straight line. The refracted light will also interact, thus increasing The refractive index of the light source emitted by the lens increases the light-emitting range of the light-emitting unit light source, and also condenses the light source and improves the luminance and the uniform light effect. Further, as shown in the first figure, the lens body 10 has a rectangular structure, and the light can be deflected at different angles to make the light source uniform and increase the projection angle.
