Embodiment Construction

[0028] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used in the description of the present invention in this specification are o...

Abstract

The invention discloses an LED lamp. The LED lamp comprises an encapsulation structure, and the light emitting surface of the encapsulation structure is provided with a plurality of bumps; the bumps are spaced from each other, and a plane part is located between each two bumps. By means of the scheme, through designing the light emitting surface of the encapsulation structure, the light is well scattered at the LED lamp, and the emitted light is dispersed; the LED lamp is especially suitable for the illumination field and very high in market application value.

Description

technical field [0001] The present invention relates to the field of LEDs, in particular to an LED lamp. Background technique [0002] With the development of technology, LED has been widely used. LED is a kind of semiconductor diode, which can convert electrical energy into light energy. Like ordinary diodes, light-emitting diodes are composed of a PN junction and also have unidirectional conductivity. When a forward voltage is applied to the light-emitting diode, the holes injected from the P region to the N region and the electrons injected from the N region to the P region are respectively connected to the electrons in the N region and the vacancies in the P region within a few microns near the PN junction. Hole recombination, resulting in spontaneous emission of fluorescence. The energy states of electrons and holes are different in different semiconductor materials. The amount of energy released when electrons and holes recombine varies, and the more energy release...
