Filament type led lamp

Abstract

The invention provides a filament-type LED lamp, which includes a lamp cap, a lamp holder, a filament, a lampshade, a driving power supply, a miniature fan, a built-in plastic cover, a filament bundle block and a filament support; the driving power supply is connected to the lamp holder and is arranged at the tail of the lamp holder Inside; the miniature fan is set inside the lamp holder, fixed to the head of the driving power supply and connected to the driving power supply; the built-in plastic cover is set on the head of the miniature fan and fixed to the miniature fan, and there is a ventilation hole opposite to the miniature fan; The lamp holder is provided with an air inlet on the side wall opposite to the driving power supply, and an air outlet is provided on the side wall opposite to the micro fan or the built-in plastic cover; The head of the plastic cover is fixed, and the filament is connected to the driving power supply; the lampshade covers the filament, the filament bracket, and the filament cluster block, and the tail of the lampshade is fixedly connected to the head of the lamp holder. The present invention makes the lamp assembly process of the filament type LED lamp simple and long in service life.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a filament type LED lamp. Background technique [0002] Filament-type LED lamps, referred to as filament lamps, take the appearance of traditional light bulbs and use LED light-emitting modules such as long strips, flat strips, and discs as light sources, which not only maintains the simple and retro style of traditional light bulbs, but also adopts the current The popular LED lighting solution replaces the traditional tungsten bulb with high energy consumption, making it a new type of energy-saving and long-life light source. [0003] In the process of emitting light, LEDs convert part of the electric energy into light energy, and part of the electricity into heat energy. Therefore, LED lighting fixtures as light sources often have a large number of lamp components that are heat-conducting and heat-dissipating devices. Otherwise, it is difficult to ensure that LED light-emitti...

Problems solved by technology

[0004] The current common filament-type LED lamps, taking the A60 bulb lamp as an example, the bulb part is welded together with a glass bulb and a stem structure, and is evacuated by exhaust, and then filled with a high-viscosity gas to ensure the seal. The heat dissipation of the LED filament during work; the sealing process is complicated, and the reliability requirements of the high-temperature processing process of glass products are also high, and the sealing process may cause high-temperature damage to the LED filament, and the subsequent lamp assembly process is also more complicated.

For products with higher wattage, the glass sealing scheme has its limitations
