However, the angle of illumination of LEDs is generally only about 12 inches. Therefore, the range of ', , and Ming is limited, and because the illuminating light of the LED is generally concentrated at the center, the brightness difference between the center and the periphery is very large, and it is impossible to provide a uniform illumination effect. In this way, various LED illumination devices using LEDs as light sources will have a smaller illumination range and poorer light uniformity due to the limitation of the original illumination angle and the original light distribution of the LED light source, which is difficult to meet the needs of users. In view of this, the LED illumination device is often provided with an optical lens to adjust the light emitted by the LED light source by using the secondary optical principle of the optical lens, so as to improve the uniformity of the projection illumination, the illumination angle and the illumination light for the original LED light source. Produce a variety of suitable light shape layouts, and can be illuminated under a variety of different conditions of use. In addition, due to the trend of miniaturization of the device, or in order to meet the market demand of high-light and high illumination range, a single LED^= device may be equipped with multiple LEDs, and each LED is configured. ,.. Therefore, the belt makes the optics. The structural design of the lens and the appearance of the volume are limited =, M439152 affects the two devices that can be produced by the optical lens can not be raised, for the best illumination / effect, resulting in LED illumination three optics The principle of refraction and reflection is mentioned: 昼: 何进-step utilization function is the subject of the field of the optical path adjustment of the optical lens.
