LED bulb lamp

Abstract

An LED bulb lamp comprises a lamp holder (1), an LED luminous body and a glass bulb (2). The LED luminous body is located in the bulb (2) and connected with a first conducting wire (3) and a second conducting wire (5) which are used for powering on, the first conducting wire (3) and the second conducting wire (5) penetrate out of the bulb (2), the lamp holder (1) is connected with the bulb (2), the position, connected with the lamp holder (1), of the bulb (2) is provided with an external thread (21), the lamp holder (1) is provided with an internal thread (11) matched with the external thread (21) on the bulb (2), the edge wall of the external thread (21) of the bulb (2) is provided with a gap (22), the upper end of the second conducting wire (5) is located in the gap (22), the lamp holder (1) is screwed in the external thread (21) of the bulb (2) through the internal thread (11) of the lamp holder (1), and the tail end of the second conducting wire (5) located in the gap (22) is welded to the outer wall of the lamp holder (1) to form a welding point (4). According to the LED bulb lamp, the lamp holder is firmly connected with the bulb, the lamp holder and the bulb cannot be loosened, the situation that a power module fails or the service life of the power module is affected due to the fact that the power module is heated can be avoided, the surrounding environment cannot be polluted, and the process is simplified.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED bulb lamp. Background technique [0002] Because LED lights have many advantages such as energy saving, environmental protection, stable performance, small size, and long life, they have been widely used in many fields; LED lights are more and more widely used in the lighting field and play an important role in the lighting field. With the advent of LED white light, the lighting industry has set off a second revolution. As a light source, LED is not only energy-saving and environmentally friendly, but also has a long service life, which is in line with the environmental protection, energy saving and low-carbon products advocated by the state. The cost of LED lamps will decrease with the continuous improvement of LED technology, and energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps. [0003] LED bulbs usually include metal lamp holders, power modules, LED il...

AI Technical Summary

Problems solved by technology

Because there is a power module in the bulb, during the manufacturing process, when the lamp holder and the bulb are bonded and solidified with glue, the high temperature of heating will damage the electronic components of the power module, which constitutes a quality hazard and affects the service life of the LED bulb.

And it is bonded with glue, which is prone to aging phenomenon, causing looseness between the lamp holder and the bulb

In addition, due to the use of glue, pollution will be generated, which is not conducive to the health of operators
