LED indicator

Abstract

The invention provides an LED indicator. The LED indicator comprises a plurality of LED devices, wherein the LED devices are arranged on a circular-arc-shaped aluminum substrate, the aluminum substrate is sleeved by a lock cylinder and embedded into a lock hole of a door, one side of the aluminum substrate provided with the LED devices is outward, a semi-transparent hollow columnar tube sleeves the lock cylinder, one end face of the columnar tube is in contact with the aluminum substrate, the other end face of the columnar tube is located on the same plane with the door outer side, and the LED devices are connected with a constant-current electronic module and a driving switch in series. When the door is required to be opened at night, the driving switch is automatically or manually, the indicator gives out light, the position of the lock cylinder is clearly indicated, accordingly lock hole finding trouble is avoided, and the door opening speed and convenience degree are greatly improved.

Description

Technical field [0001] The invention relates to the field of LED lighting, in particular to an LED indicator. Background technique [0002] LED is a semiconductor light-emitting diode. LED energy-saving lamps use high-brightness white light-emitting diodes as light sources. They have high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection; Bright, colorful, low loss, low energy consumption, green and environmental protection, suitable for long-term lighting in families, shopping malls, banks, hospitals, hotels, restaurants and other public places. [0003] With the miniaturization of portable electronic products, LED backlights have more advantages. In daily life, we often encounter this situation. When we go home at night, we take out the key to open the door but cannot find the key hole. Even if the light is on, Because the keyhole is small, it is impossible to locate the lockhole quickly and accurate...

[0003] With the miniaturization of portable electronic products, LED backlights have more advantages. In daily life, we often encounter this situation. When we go home at night, we take out the key to open the door but cannot find the key hole. Even if the light is on, Due to the small keyhole, it is impossible to locate the lockhole quickly and accurately, resulting in a lot of time wasted in the process of opening the door
