Embodiment Construction
[0007] In the present invention, a wave ring protection layer is arranged in the optical cup. The wave ring is a concentric circle structure to enhance the light absorption area. The light wave is used to propagate in a concentric circle to increase the intensity of light absorption, thereby enhancing light conversion rate.
[0008] In practice, the present invention can be applied to diodes, and the intensity of light conversion rate is increased by 30% than normal.

The invention provides a wave-ring optical cap, which comprises a positive optical cap, and a negative electron emitter. The wave-ring optical cap is characterized in that concentric wave-ring protection layers are arranged in the optical cap to reduce forward and reverse light reflection, thereby improving light scattering rate, enhancing light conversion rate, and improving the illumination intensity. The wave-ring optical cap can be used for large-power LED lamps, such as street lamp.
Description
Technical field [0001] The invention relates to a diode, in particular to a light cup of the diode. Background technique [0002] A light emitting diode (LED) is a forward-biased PN junction diode made of semiconductor materials. Its light-emitting mechanism is that when a forward current is injected at both ends of the PN junction, the injected unbalanced carriers (electron-hole pairs) In the diffusion process, compound light emission, this emission process mainly corresponds to the spontaneous emission process of light, and its light conversion efficiency is low. Summary of the invention [0003] Aiming at the defects of the prior art, the present invention provides a diode light cup with high light conversion rate. [0004] In order to achieve the above objectives, the present invention adopts the following measures to achieve: [0005] A wave ring type optical cup, including a positive electrode light cup and a negative electron emitter, is characterized in that a concentric...
