技术领域  Technical field

本发明涉及一种 LED灯泡。  The present invention relates to an LED light bulb.

目前在照明领域， LED因具有节能、 高光效、 长寿命、 启动快等优点， 已经越来越广泛应用到光源中作为照明之用。 在光源中， 一些众所周知的原 因， 人们都在追求 LED灯泡和传统钨丝灯泡的一致性， 这表现在外观上要求 灯头是全透光外壳， 外形尺寸要一致， 表现在亮度上要求光通量能够完全替 代钨丝灯泡， 表现在泡壳上要求有透明或磨砂或乳白等多种可能的形式。 但 表现在寿命上就明显不同， LED灯泡要求上万小时以上，这就使得 LED灯泡 的散热极为重要， 由于现有的全透光灯泡没有散热器， 热量只能通过灯头散 发出来， 所以通常设计的功率较小， 光通量一般不超过 300流明。 为了满足 更高功率更大亮度的全透明灯泡的要求， 目前出现了一种在透明泡壳内加满 透明液体的 LED灯泡， 使 LED整个浸入液体里以增加散热， 但是这种工艺 生产难度极大， 使用时也容易漏液， 一旦漏液， 则灯泡报废无法继续使用， 而且不具有抗跌落性能。  At present, in the field of lighting, LEDs have been widely used in lighting sources for lighting because of their advantages of energy saving, high luminous efficiency, long life, and fast startup. In the light source, for some well-known reasons, people are pursuing the consistency of LED bulbs and traditional tungsten bulbs. This is because the appearance of the lamp head is required to be a fully transparent outer casing. The dimensions are the same, and the brightness is required to be completely luminous. Instead of a tungsten filament bulb, it is required to have a variety of possible forms such as clear or frosted or opalescent on the bulb. However, the performance is obviously different in life. The LED bulb requires more than 10,000 hours, which makes the heat dissipation of the LED bulb extremely important. Since the existing all-transmission bulb has no radiator, the heat can only be emitted through the lamp cap, so it is usually designed. The power is small, and the luminous flux generally does not exceed 300 lumens. In order to meet the requirements of a full-transparent light bulb with higher power and greater brightness, an LED bulb filled with a transparent liquid in a transparent bulb has been appeared, so that the LED is entirely immersed in the liquid to increase heat dissipation, but the process is extremely difficult to produce. Large, it is easy to leak when used. Once it leaks, the bulb can not be used continuously and does not have anti-drop performance.
