LED lamp wick with over-temperature protection function

Technical Field

The utility model relates to the field of lighting, in particular to LED wick with excess temperature protect function.

Background

The LED lamp, also called LED lamp, is a device capable of transmitting light, distributing and changing the light distribution of the LED light source, and includes all the parts and components required for fixing and protecting the LED light source except the LED light source, and the circuit accessories necessary for connecting with the power supply. The LED lamp is becoming the main product of a new generation of lighting market by the technical characteristics of high efficiency, energy conservation, safety, long service life, small size, clear light and the like, and the high-speed development of the environment-friendly and energy-saving industry is powerfully pulled. The LED lamp has the characteristics of shock resistance, impact resistance, high light response speed, power saving, long service life and the like, is widely applied to various indoor and outdoor display screens, and is divided into full-color, double-color and single-color display screens. The LED lighting source may also be used to replace conventional lighting fixtures. This alternative trend has begun to involve indoor and outdoor, commercial lighting, road industry lighting, etc.

However, most of the existing LED lamps are not provided with corresponding protection resistors, if a circuit has a small fault current or a half short circuit during use, the temperature of the lamp body rises continuously, the temperature of the surface of the lamp body can even reach above 300-500 ℃, and the continuous high temperature can cause the deformation and melting of the shell of the electronic product, which leads to the risk of exposing electrodes and electric shock, and the temperature rise of the surrounding environment and objects, and has the hidden danger of causing fire. Therefore, further optimization of the structure and performance of existing led e-lamp fixtures is necessary.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a LED wick with excess temperature protect function to prior art's defect and not enough.
