LED optical lens construction

The present invention relates to the construction of an LED optical lens, in particular, by designing the curved surface of the optical lens and the space of the receiving portion of the base, thereby providing the maximum brightness of the LED, the concentration of the light, and the illumination area being the side long axis. Constructed to the optical lens of the illumination zone.

According to the light source, a light-emitting diode (LED) is used as a light source of a lighting device, and is widely used in various lamps. Generally, LEDs are used as the light source of the lamps, and the metropolis is combined with a secondary optical component (such as an optical lens) on the outer edge to make the light on the illuminated object form a highly usable optical and enhance its optical Irradiation uniformity, and the configuration of the secondary optical component (such as an optical lens) can be used to determine the illumination shape of the area illuminated by the LED.

Therefore, the structure of the optical lens for the LED is an important issue for the improvement of the use efficiency of the lamp for the lamp with the LED as the light source. It is based on how to provide a good optical lens structure, so that the LED-based light source can achieve the pre-achieved effect of its use, which is a technical problem that the lamp manufacturer who uses LED as the light source needs to solve.

In view of this, the creator is in-depth discussion on the above-mentioned secondary optical accessories (such as optical lenses), and actively seeks solutions through years of experience in R&D and manufacturing of related industries, and has been researched and developed through long-term efforts. Finally, I successfully developed the creation of "LED Optical Lens" to improve the problem of custom creation.

The main technical means of the present invention is to provide a structure of an LED optical lens, the optical lens includes a transparent body, the base of the body is provided with a receiving portion, and the receiving portion is provided for the LED, and the The upper end portion of the accommodating portion is formed with a light incident surface, and the body is at the base A light exiting surface is formed on the outer periphery of the upwardly extending body, and the light exiting surface is formed by different curvatures of the outer peripheral surface of the body, and the system is symmetrical to the long axial reference plane X and asymmetric to the short axial reference plane Y, in turn, to improve the use of LEDs as a light source.
