Abstract

The present application belongs to the technical field of aluminum substrates, and in particular, relates to a new type of aluminum substrate, including a circular aluminum substrate body and an inductor. A plurality of LED lamp beads are installed on the front of the aluminum substrate body, and each of the LED lamp beads is connected in series and electrically connected to the circuit on the aluminum substrate body. Three SMD connectors for connecting the circuits are also installed on the front of the aluminum substrate body. The inductor is installed on the SMD connector, and the inductor is located on the back of the aluminum substrate body. In the present utility model, when the full DOB solution is adopted, a non-SMD inductor can be used to reduce costs. Since the inductor and the lamp beads are not on the same side of the aluminum substrate, the inductor will not have a negative impact on the luminous flux. When the LED bulb adopts the full DOB solution, a larger inductor can be used, which has a wider applicability.

Description

A new type of aluminum substrate

Technical Field

The utility model relates to an aluminum substrate, in particular to a novel aluminum substrate.

Background technique

LED lights have the advantages of high energy conversion efficiency, fast switching response, long life, no radiation and low power consumption, and are widely used in more and more occasions. In some functional lighting fields, it is a general trend for LED lighting to replace traditional light sources. In the full DOB solution of LED bulbs, the inductor is attached to the aluminum substrate through SMD technology, and the defects are as follows:

1) The cost of chip inductors is higher than that of ordinary inductors;

2) In the full DOB solution of LED bulbs, the inductor and LED are on the same side of the aluminum substrate, which will affect the lighting effect and reduce the luminous flux;

3) When a larger size inductor is required, such as EE20 or above, the SMD method cannot be used to implement a full DOB solution.
