LIGHT EMITTING DIODE LAMP HAVING VARIABLE LIGHT FIELD

摘要

A light emitting diode lamp includes a lamp body, a light emitting diode arranged on the lamp body, and a lamp cover to cover the light emitting diode. The lamp cover includes a lens in front of the light emitting diode to modulate the light from the light emitting diode. The light emitting diode lamp further includes a driver and an adjusting device. The driver is formed between the lamp body and a lamp cover. The adjusting device controls the driver to adjust a distance between the lens and the light emitting diode, whereby a light filed of the light from the light emitting diode is adjustable.
