Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] The invention provides an industrial LED indicating device with strong anti-vibration capability, convenient operation and simple structure.

[0019] Such as Figure 1 to Figure 6 As shown, an LED indicating device 1 includes a light emitting unit 2 , a shockproof snap ring 3 and a positioning screw 4 for fixing the light emitting unit 2 are arranged below the light emitting unit 2 .

[0020] The light-emitting unit 2 includes an LED lamp bead 21 and a lamp bead sleeve 22 that wraps the LED lamp bead 21. The LED lamp bead 21 includes a lamp holder 211 and pins 212 that provide power supply for the lamp holder 211. The lamp bead sleeve The...

Abstract

The invention discloses a light-emitting diode (LED) indicating device which comprises a luminous unit. A shock-proof snap ring and a positioning screw for fixing the luminous unit are arranged below the luminous unit. The luminous unit comprises an LED lamp bead and a bead sleeve for wrapping the LED lamp bead, wherein the LED lamp bead comprises a lamp head and pins for providing power for the lamp head, and the bead sleeve comprises a drum body, a cavity for containing the LED lamp bead is formed in the middle of drum body. Due to the fact that the shock-proof snap ring made of non-conducting rubber and the bead sleeve are arranged on the LED indicating device, meanwhile, the LED lamp bead is protected validly, harmful vibration is avoided, and a user can replace the LED indicating device easily by making use of the positioning screw at the bottom.

Description

technical field [0001] The invention relates to an illuminating device, more specifically, an LED indicating device. Background technique [0002] LED is an abbreviation taken from the three words Light Emitting Diode, which translates as "light emitting diode" in Chinese. As the name suggests, a light emitting diode is an electronic device that can convert electrical energy into light energy and has the characteristics of a diode. Existing LEDs are also widely used in the field of industrial indicator lights, and the industry has extremely high requirements for shock resistance, and the existing indicating devices made of LED lights are relatively deficient in shock resistance. [0003] Chinese utility model patent ZL200720170626.2 discloses a plug with an LED indicator light, including a plug housing, a neutral line insert, and a live line insert, and the neutral line insert line and the live line insert line in the plug shell are connected. There is an LED indicator, and...
