技术领域 FIELD

[0001] 本发明涉及一种灯泡,特别涉及一种LED球泡型灯泡。 [0001] The present invention relates to a lamp, particularly to a bulb-type LED lamp. 背景技术 Background technique

[0002] LED是英文Light Emitting Diode的缩写,中译为“发光二极管”,其利用固体半导体芯片作为发光材料,当两端加上正向电压,半导体中的载流子发生复合,放出过剩的能量而引起光子发射产生可见光。 [0002] LED Light Emitting Diode is the English acronym, translated as "LED", which use a solid semiconductor chip as a light emitting material, when the ends with a positive voltage, charge carriers in the semiconductor compound occurs, release excess energy caused by photon emission to produce visible light. LED是一种具有二极管特性的可以将电能转化为光能的电子器件,不同的发光二极管可以发出从红外到紫外光的不同波长的光线。 LED is a diode having a characteristic of converting electrical energy into light energy may be electronic devices, different light emitting diodes may emit light of different wavelengths from the infrared to the ultraviolet. LED光源以其发光效率高,目前大功率LED光效可达140流明/瓦,远景发展可达150-200流明/瓦,而白炽灯、卤钨灯光效为12-¾流明/瓦,荧光灯光效为50〜70流明/瓦,钠灯光效为90〜140 流明/瓦,其余大部分电能变成热量损耗。 LED light source with its light emission efficiency is high, the current high-power LED light efficiency up to 140 lm / W, up to long-term development 150-200 lm / W, incandescent, halogen light efficiency is 12-¾ lumens / watt, fluorescent light effect of 50~70 lm / W, is 90~140 sodium lighting efficiency lm / W, most of the remaining energy into heat loss. LED光源的单色性好、光谱窄,无需过滤可直接发出有色可见光、耗电量少(在同样照明效果情况下,耗电量是白炽灯泡的八分之一,荧光灯管的二分之一)、使用寿命长(平均寿命达10万小时)、安全可靠性强、有利于环保(LED为冷光源,发热量低,无热辐射,可以安全触摸,便于安装和维护。不含汞、钠等危害健康的元素,废弃物可回收)。 Good monochromatic LED light source, a narrow spectrum, can be sent directly without filtering visible light colored, low power consumption (at the same lighting effects, the power consumption is one eighth of incandescent bulbs, fluorescent tubes in one-half ), long life (the average life of 100,000 hours), security, reliability, environmentally friendly (LED is a cold light source, low heat, non-thermal radiation, safe to touch, easy to install and maintain. mercury, sodium and and other elements of the health hazards, waste recycling).
