Abstract

The utility model discloses a light-emitting diode (LED) bulb with reflection sheets, which comprises a lamp holder, an LED circuit board, a light transmitting cover and a light shading cylinder. The LED circuit board is fixed on the lamp holder, the light transmitting cover is fixed on the lamp holder and covered on the LED circuit board, a sensor is arranged on the lamp holder in the light shading cylinder, the light shading cylinder is fixed at the top of the lamp holder, the upper end of the light shading cylinder extends to the light transmitting cover, and a light reflecting layer is arranged on the outer surface of the light shading cylinder. The LED bulb with the reflection sheets enables lights shined on the outer surface of the light shading cylinder to be reflected to the light transmitting cover and then shined out through the light transmitting cover, thereby improving luminous efficiency and illuminating brightness of the LED bulb.
