Abstract

The invention discloses an elliptical light emitting diode with the power of at least 1 watt, which comprises a chip body and a lens of the light emitting diode. The lens of the light emitting diode is covered and arranged on the chip body and provided with a transmission part. The transmission part is provided with a long shaft and a short shaft, wherein, the ratio of light forms scattered by the long shaft and the short shaft is more than or equal to 1.5-5.

Description

technical field [0001] The invention relates to a high-power light-emitting diode, in particular to an elliptical light-emitting diode capable of increasing illuminance. Background technique [0002] Existing light-emitting diodes (LEDs) use LED grains to generate light sources, and the LED lens (Lens) covering the periphery of the LED grains assists in scattering the light source outwards to achieve lighting effects. [0003] refer to figure 1 , is the first known hemispherical lens (Lens) 101 for light-emitting diodes, which is a blue reflector type (Lambertian Patten). [0004] refer to figure 2 , which is the second type of flat lens (Lens) 102 known in the art for light-emitting diodes. [0005] refer to image 3 , which is the third known airfoil lens (Lens) 103 for light-emitting diodes. [0006] refer to Figure 4 , which is the third type of side-scattering lens (Lens) 104 known in the art for light-emitting diodes. [0007] refer to Figure 5 , which is th...
