Description

V. New description: [New technical field] This case belongs to the field of lighting Θ M k luminaires, especially for an optical lens structure used for LED illuminators for display, LED lamps or indoor LED lamps. [Prior Art] Press, Ught Emuing Di〇de (lED): It has the advantages of low power consumption, high efficiency, long life, etc., and is used as a light source for illumination (hereinafter referred to as [ ED light source). In recent years, LED light sources have been widely used in lighting fields such as backlight backlights, light sources, or general lighting equipment. Since LED light sources have a particularly significant energy saving and power saving advantages, they have also been relatively practical. Furthermore, when the LED lighting device using the LED light source is compared with the conventional lighting fixture under the same brightness use condition, the power consumption of the LED is only 1/1 of the ordinary incandescent lamp, and is 1/2 of the energy saving lamp. And the life of the LED is greatly extended to use more than 10,000 hours.肇Because of the small light divergence angle of the LED light source, when applied to LED lighting equipment, the optical lens with different structure design is used together with the LED light source to adjust the light angle, luminosity distribution and illuminance distribution of the LED to make the light Ability to concentrate and effectively increase the intensity of light in the south. However, if a poorly designed optical lens is used, the valley tends to cause excessive concentration of the illumination center and uneven brightness. Therefore, there is also the use of secondary optics to change the projection effect of the LED illuminating source to achieve the best effect of the lens, the period can provide the best Zhao Mingcan, ·,, month shape '4, but enough Provides the most comfortable lighting range for viewers or users. Therefore, how to effectively improve the projection illuminance, the illuminating angle, and the illuminance uniformity of the LED illuminating device is a problem that the practitioners in the field are eager to improve. However, various optical lenses used in LED illuminating devices are currently Thermosetting plastic, C is formed by injection molding. When the thermosetting plastic is molded in the mold, the shrinkage of the plastic lens causes the error of the dimensional accuracy of the optical lens to affect the surface curvature. The projection illuminance, illuminating angle and uniformity of illumination luminosity of the device have a great influence. Therefore, the creator further sets a circular groove on the optical lens of an LED lamp, and uses the circular groove to form a structure for stealing the material to reduce the shrinkage phenomenon during plastic molding, thereby greatly improving the quality of the finished product. Furthermore, the optical lens is provided with a projection circle, and the curved surface of the projection cone is composed of a plurality of curved surface points arranged by concentric circles, and the illumination angle, the luminosity distribution and the illuminance distribution of the LED are changed. The light distribution is more concentrated and uniform to provide a more comfortable lighting environment and meet the environmental requirements of energy saving and carbon saving. [New content] In view of the above problems, one of the purposes of the present invention is to provide an optical lens for an LED lamp provided on a plane/circular groove, M419876 [Simplified illustration of the drawing] FIG. 1 is a first embodiment of the creation Stereoscopic view.
