Description

A transformer-free IC-driven LED lamp suitable for various lamp holders

technical field

The utility model relates to the technical field of lighting, in particular to an IC-driven LED lamp suitable for various lamp heads without a transformer.

Background technique

In traditional lamps, a transformer is installed on the lamp holder to achieve the purpose of changing the voltage to drive LED lights. However, the transformer is large in size, high in manufacturing cost, and troublesome to replace if the transformer is broken. Chinese Patent No. ZL201520088760.2 discloses a Over-temperature and over-voltage protected LED floor-to-ceiling lamps. The lamp combines the traditional transformer with the integrated drive circuit IC, and uses the integrated drive circuit IC to provide constant current to drive LED lamp lighting, and has over-temperature and over-voltage protection. The function of the protection circuit greatly improves the safety of LED floor lamps and prolongs the service life of LED lamps; although this patent can achieve the function of over-temperature and over-voltage protection circuits, once the integrated drive circuit IC is damaged, it is quite troublesome to replace, so , after many studies, developed an IC-driven LED lamp suitable for various lamp holders.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a transformer-free IC-driven LED lamp suitable for various lamp caps, which is smaller in size, lower in height, lowers the cost, and saves the trouble of replacing the IC chip of the integrated drive circuit. .

The utility model solves the problems of the technologies described above through the following technical solutions:

A transformer-free IC-driven LED lamp suitable for various lamp caps, including a transfer lamp cap and a lamp, an integrated drive circuit IC chip is arranged inside the transfer lamp cap, and a threaded head is arranged at the bottom of the transfer lamp cap, so A transparent panel is provided on the top of the adapter lamp holder, a plurality of LED lamp beads are arranged on the IC chip of the integrated drive circuit, a power line is arranged on the side of the IC chip of the integrated drive circuit, and a connection with the adapter lamp holder is provided on the lamp. The threaded hole matches the threaded head, and the adapter lamp head is screwed and fixed into the threaded hole of the lamp through the threaded head at the bottom.

The beneficial effect of the utility model is that the utility model first installs the integrated drive circuit IC chip directly on the adapter lamp holder, then combines the adapter lamp holder with various lamps, and directly drives the LED after the integrated drive circuit IC chip is transformed. For lighting, when the IC chip of the integrated drive circuit is damaged, the entire adapter lamp head can be replaced directly. This structure not only eliminates the transformer, but also makes the volume smaller and the height lower, which reduces the cost and saves the need to replace the integrated drive. The circuit IC chip is troublesome, so as to achieve economical and practical purposes.
