Abstract

In this invention, the first refraction groove and the second refraction groove, which are located on two opposite ends of the reflection lens, are set on the same central axis. The said lens features a translucent shell and is of a horn-shaped appearance. The horn or cone-shaped mouth points from the first refraction groove to the second refraction groove. The outer surface is designed to have multiple reflection sections. When the LED light source is positioned at or in the first refraction groove, the light emitted from LED is refracted by the first refraction groove and then is sent out from the cone mouth at the second refraction groove. Meanwhile, the light which gets through the translucent lens shell is refracted by the multi-section reflection surface and then is also projected from the cone mouth. The reflection surface lens in this invention integrates multiple functions within the one body including focusing, refraction and reflection, which allows uniform illumination and other desired illumination effects without the need for any reflective coating. It simplifies the processing technique of LED illumination systems and reduces processing costs.

Description

改进的光学系统和LED灯具 Improved optical systems and LED lamps

技术领域 FIELD

[0001] 本发明涉及新型的透镜,尤其地,涉及一种能大幅提升LED灯具的光效率的透镜。 [0001] The present invention relates to a novel lens, in particular, relates to a lens optical efficiency of the LED lamps can be significantly improved.

背景技术 Background technique

[0002] 作为一种在21世纪的新型的竞争性的固体光源,LED灯具有以下优点:高效率,纯光色,低能耗,寿命长,可靠耐用,无污染,以及控制灵活。 [0002] As a light source of a solid in a competitive 21st century, LED lamps has the following advantages: high efficiency, pure light color, low power consumption, long life, reliable and durable, non-polluting, and flexible control. 随着LED技术的不断改进,LED灯具的光通量和光效率将不断地提高。 With the improvement of LED technology, LED lighting efficiency of the light flux and will continue to improve. 目前,单一白光LED的光通量已达到20001m以上。 Currently, a single white LED luminous flux has reached more than 20001m. 作为灯具的LEDs的照明系统的数量迅速增长。 Rapid growth in the number of LEDs as the lighting of the lighting system. 从LED芯片发出的光以朗伯(Lambertian)分布投射。 Lambertian light (a Lambertian) light emitted from the LED chip distribution projection. 在大多数情况下,如果在应用时未通过适当的光学系统处理,这样的光场分布用在灯具中时,不能够满足性能要求。 In most cases, if not handled by a suitable optical system in the application, such as optical field distribution when used in the luminaire, can not meet the performance requirements. 因此,LED灯具的照明系统的二次光学设计是绝对必要的。 Thus, the second optical design of the lighting system of LED lamps is absolutely necessary.

[0003] 二次光学设计能在目标区形成具有均匀照明的光斑,从而照明系统能够实现均匀照明。 [0003] Secondary optics designed to form a light spot having a uniform illumination in the target area, whereby the lighting system can achieve uniform illumination. 照明系统一般分为反射型,折射型以及反射折射混合型。 The illumination system is generally divided into reflective, refractive and catadioptric mixed. 其中,该混合型主要采用TIR(全内反射)技术。 Wherein the hybrid mainly TIR (Total Internal Reflection) technology. 一般来说,由于LED的出光范围广,反射型或折射型很难控制LED的所有出光。 In general, since a wide range of the LED light, reflective or catadioptric difficult to control all the LED light. 另一方面,TIR技术能充分发挥折射和全反射,并有效地聚集LED的大多数出光,以及控制光束分布,从而保证照明系统的结构紧凑。 On the other hand, can give full play to the TIR art refraction and total reflection, and effectively collect most light LED, and a control beam profile, thus ensuring a compact illumination system.

[0004] 现有的反射型的LED透镜具有低反射率,通过为80%。 [0004] conventional reflection type LED lens having a low reflectivity by 80%. 由于条件的限制,如透镜直径,折射型的LED透镜的透光率低至90%。 Due to constraints, such as the low light transmittance of the lens diameter, refractive lens to the LED 90%. 现有的反射折射混合型的LED透镜一般具有单独的折射和反射部分,这些部分增加了技术成本和LED灯的加工程序。 The conventional catadioptric lens is a hybrid type LED typically has refractive and reflective separate parts which increases the cost and technical LED lamp machining program. 然而,现有反射部分的反射面要求反射涂层,比如铝涂层,这也增加了LED灯的技术成本。 However, the conventional reflective surface reflecting portion requires a reflective coating, such as an aluminum coating, which also increases the cost of the LED lamp technology.

[0005] 如图10所示,申请200910108644.1为LED聚光透镜。 [0005] 10, a condenser lens for the LED application 200910108644.1. 虽然这个聚光透镜具有两个折射凹槽,但是,透镜并没有反射面设计,因此,它没有良好的发光效果。 Although the condenser lens having two refracting grooves, however, there is no reflective surface and the lens, and therefore, it does not have good luminous effect.
