Abstract

A reflection type light-emitting diode (LED) lamp comprises a light tube, at least one substrate and at least one LED, wherein the light tube is a strip rounded body and contains a reflective shell and a light-transmitting cover; the reflective shell has a reflective panel on the inside; the substrate is arranged in the light tube; the LED is arranged on the substrate, the light-emitting direction of the LED faces to the reflective shell, and the light is reflected by the reflective panel of the reflective shell and emitted from the light-transmitting cover. Therefore, the point light source characteristic of the LED can be eliminated and phenomena such as uneven light and ghosting which are caused by the point light source can be cancelled. In addition, the point light source characteristic of light is eliminated before the light is emitted from the light-transmitting cover, thus the light-mixing effect of the invention is better than that of the common existing LED lamp.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a reflective light-emitting diode lamp. Background technique [0002] Fluorescent tubes can be said to be a very important invention of indoor lighting. Most of the nighttime indoor lighting in the world now uses fluorescent tubes. However, the disadvantage of fluorescent tubes is that they consume a lot of power and need to generate high voltage for operation. In addition, mercury in fluorescent tubes has been criticized for polluting the earth's environment. Therefore, the search for new lighting devices has aroused great interest among scientists and business circles. [0003] The white light-emitting diode, which began to be developed in the late 20th century, brought a ray of light for lighting. In 1996, on the basis of GaN blue light-emitting diodes, Nichia Corporation of Japan developed a blue light-emitting diode to excite yttrium aluminum garnet (YAG) phosphor to produc...
