Description

LED street light

The invention relates to a lighting device, in particular to a light-emitting diode street lamp.

As a new, environmentally friendly and energy-saving light source product, the light-emitting diode lamp is widely used in life, such as street lamps.

Luminous diode street lights often require repair for various reasons. When maintenance personnel perform maintenance work, it is usually necessary to power off the street light first, and then power the street light after a period of repair to confirm whether it is repaired. When there is still a problem with the street lamp, the street lamp is powered off again to continue repairing. This is repeated many times until the repair is completed, and the process is cumbersome and time consuming. If the repair is carried out under continuous power, it is easy to cause an electric shock accident to the maintenance personnel.

A light-emitting diode street lamp includes a casing and a lamp body mounted on the casing. A driving circuit module is received in the casing to drive the lamp body.

The joint portion 451 contacts the contact point 451 of the first metal dome 45 with the receiving point 471 of the second metal dome 47 to close the current loop of the light-emitting diode circuit, and the light-emitting diode street lamp is energized.

Referring again to FIG. 5, it is not necessary to power off the LED street lamp during maintenance, as long as the bottom plate 12 of the casing 10 is first removed for maintenance. After the bottom plate 12 is removed, the operating member 41 moves upward away from the connecting member 43; the connecting member 43 The spring 42 is also moved upwardly to move the spacer 433 away from the joint portion 451 of the first metal dome 45; while the first spring 45 is moved upward to be separated from the second metal dome 47. At this time, the current loop of the LED street lamp is automatically disconnected, and the lamp body 20 is in a power-off state, and the maintenance personnel can perform maintenance without worrying about electric shock. After the repair is completed, only the bottom plate 12 of the casing 10 is covered, and the light-emitting diode street lamp of the present invention can work normally.
