LED球泡灯LED Bulb

技术领域technical field

本发明涉及LED照明领域，尤其涉及一种能够实现大角度照明的LED球泡灯。The invention relates to the field of LED lighting, in particular to an LED bulb capable of realizing large-angle lighting.

背景技术Background technique

LED是一种半导体固体发光器件，它是利用固体半导体芯片作为发光材料，在半导体中通过载流子发生复合放出过剩的能量而引起光子发射，直接发出红、黄、蓝、绿、青、橙、紫、白色的光，LED具有体积小、耗电量低、使用寿命长、高亮度、低热量以及环保等优点。但是，由于LED单个发光面比较窄，通常需要大规模集成在线路板上，形成一个比较大的发光源，但由此会造成大量热量积累，有时会击穿电路板。LED is a semiconductor solid light-emitting device. It uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers in the semiconductor to cause photon emission, which directly emits red, yellow, blue, green, blue, and orange. , purple, white light, LED has the advantages of small size, low power consumption, long service life, high brightness, low heat and environmental protection. However, since the single light-emitting surface of LED is relatively narrow, it usually needs to be integrated on a circuit board on a large scale to form a relatively large light source, but this will cause a large amount of heat to accumulate, and sometimes the circuit board will be broken down.

大多数A60LED球泡灯因为受到上述LED光源本身面发光和发光时需要散热的特性的局限，其光分布角度有限，通常小于180度；同时，为了与传统白炽灯有比较接近的外观效果，通常光学设计师是通过加透镜和透明玻璃泡或透明PC泡的方式来实现配光，大部分设计师选用单颗COB光源进行透镜的设计，但是此种设计在配光上光束角都很难大于180°，而且配光曲线都很不均匀。Most of the A60LED bulbs are limited by the above-mentioned characteristics of the LED light source itself and the need for heat dissipation when emitting light. The light distribution angle is limited, usually less than 180 degrees; Optical designers realize light distribution by adding lenses and transparent glass bubbles or transparent PC bubbles. Most designers use a single COB light source for lens design, but it is difficult for this design to have a beam angle greater than 180°, and the light distribution curve is very uneven.

美国公开号为US2010/208488A1的发明专利申请披露了一种LED灯，包括封闭在外壳中的透明光管、LED以及反射器，LED在光管下部的下端处的凹部中，反射器由光管的上部的上端中的缺口形成，光管下部采集LED发出的光，光管的上部将采集的光引导至反射器，反射器在径向上反射引导的光。该专利申请是通过改变反射器的曲率获得适用于不同应用的发射图样，例如，前向发射、侧向发射或向下导光。该技术存在的缺陷是，光管仅作为导光用，反射器仅能有针对性地将光管引导的光投射至需要的方向，光束角仍无法大于180°。U.S. Publication No. US2010/208488A1 patent application for invention discloses an LED lamp, including a transparent light pipe enclosed in a housing, an LED, and a reflector. A gap is formed in the upper end of the upper part of the light pipe, the lower part of the light pipe collects the light emitted by the LED, and the upper part of the light pipe guides the collected light to the reflector, and the reflector reflects the guided light in the radial direction. The patent application is to obtain emission patterns suitable for different applications by changing the curvature of the reflector, for example, forward emission, side emission or downward guiding light. The disadvantage of this technology is that the light pipe is only used as a light guide, and the reflector can only project the light guided by the light pipe to the required direction in a targeted manner, and the beam angle cannot be greater than 180°.
