Abstract

The invention discloses an LED lamp bead. The LED lamp bead comprises an LED chip, a support and a light transmitting layer; the LED chip is arranged in the middle of the upper surface of the support,the other areas, except for the LED chip, on the upper surface of the support are coated with an insulation cement layer, the LED chip is coated with a fluorescent powder cement layer, the light transmitting layer is located on the outer portion of the fluorescent powder cement layer, a positive electrode and a negative electrode of the LED chip are connected with a wire, the outer portion of theinsulation cement layer is coated with a reflection layer, and the fluorescent powder cement layer is in an oval shape. As preference, triangular conical protrusions are arranged on the surface of the reflection layer. According to the LED lamp bead, the outer portion of the insulation cement layer is coated with the reflection layer, the fluorescent powder cement layer in the oval shape is beneficial to light reflection, the irradiating area of the LED lamp bead can be increased, in addition, the other areas, except for the LED chip, on the upper surface of the support are coated with the insulation cement layer, and emission of heat of the LED lamp bead can be facilitated.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp bead structure. Background technique [0002] LED light-emitting diodes have been recognized globally as the most efficient artificial lighting technology. It has the advantages of long life and low energy consumption. With the development of LED technology, the performance of LED light source is getting better and better. Generally speaking, whether the LED lamp works stably, the quality is good or bad, and the heat dissipation of the lamp itself is very important. At present, the heat dissipation of high-brightness LED lamps on the market often adopts natural heat dissipation, and the effect is not ideal. LED lamps made of LED light sources are composed of LEDs, heat dissipation structures, drivers, and lenses. Therefore, heat dissipation is also an important part. If LEDs cannot dissipate heat well, their lifespan will also be affected. In addition, the current LED al...
