Description

Detachable LED light bulb structure

technical field

The utility model relates to a detachable LED bulb structure.

Background technique

The traditional tungsten filament bulbs are not only easy to damage, high temperature, etc., but also because of economical problems such as considerable power consumption, frequent replacements, etc., so they have been gradually eliminated and replaced by energy-saving bulbs because they have a longer service life. , sufficient brightness and low power consumption have become the mainstream of the market for many years, and have been used to this day; however, with the rapid development of technology and the improvement of industrial technology, more ideal lighting fixtures have been developed. In terms of design, LED lamps are mainly used as light sources, and two different types of lamp tubes and bulbs are designed according to different usage requirements. The utility model is an improved design aimed at the lack of existing LED bulbs. .

In fact, once this type of LED light bulb is damaged, more than 90% of the failure points are caused by power supply failure, damage, the damage probability of its LED light is quite low, but because the various parts of the existing LED light bulb are designed with an integral composite structure, after the LED light bulb is damaged, the LED light bulb needs to be replaced as a whole, and it cannot continue. Using undamaged parts will cause money waste invisibly, and it is not in line with environmental protection and economic benefits.

Furthermore, conventional LED light bulbs lack a good heat dissipation design. In the state of long-term use, the heat generated by the internal LED lights cannot be ventilated, resulting in excessively high temperature in the working environment, which will inevitably shorten the service life of the LED lights. In addition, its high temperature is likely to cause damage to the LED lamp, resulting in light decay and affecting its brightness. It is necessary to try to solve it and improve it.
