Embodiment Construction

[0019] see Figure 8 and Figure 9 , The LED module of the present invention includes a heat conducting plate 10 , a LED assembly 200 fixed on the heat conducting plate 10 and a power supply circuit 30 connecting the LED assembly 200 to a power source 40 . The power supply 40 can be a civilian power supply with a voltage of 220V, an industrial power supply with a voltage of 380V, or other types of AC power supply.

[0020] The heat conducting plate 10 is made of a metal material with good thermal conductivity, such as copper, aluminum or an alloy thereof. The top of the heat conduction plate 10 forms a flat surface for the LED assembly 200 to be attached to.

[0021] Please also refer to figure 1 and Figure 4 , the light emitting diode assembly 200 is formed by welding several light emitting diodes 20 to each other. Each light-emitting diode 20 includes a regular hexagonal base 22, a light-emitting diode chip 23 bonded on the base 22, two first pins 24 and second pins in...

Abstract

The invention relates to a light-emitting diode module which comprises a plurality of light-emitting diodes and a power supply circuit electrically connected with the light-emitting diode, and the power supply circuit comprises an AC conversion circuit used for being connected with a power supply, a DC conversion circuit connected with the AC conversion circuit as well as a drive circuit and a buffer circuit connected with the drive circuit. In the light-emitting diode module, the buffer circuit is added in the power supply circuit and can effectively buffer current impact, causes range of variation of the current input into the light-emitting diode not to be too large in unit time, then protects light-emitting diode chips in the light-emitting diodes, and prevents the light-emitting diode chips from subjecting current impact to be damaged.

Description

technical field [0001] The invention relates to a light emitting diode module, in particular to a light emitting diode module with a buffer circuit. Background technique [0002] With the improvement of luminous efficiency, light-emitting diodes have been increasingly used in various fields, such as residential lighting, industrial lighting and traffic indication. In these applications, usually a plurality of LEDs are connected in series on a circuit board to form an LED combination, and then the LED combination is connected to a power source. When lighting is required, only the power supply is turned on, and current can be input into the combination of light-emitting diodes, thereby driving the light-emitting diodes to emit light. [0003] Since the voltage of the civilian power supply currently used is 220V and the voltage of the industrial power supply is 380V, both of which far exceed the maximum voltage that the light-emitting diode can withstand. If the light-emitting...
