Problems solved by technology

However, aiming at the point that an external circuit (addition of a load) is required to drive the normal operation of the light emitting diode module 100, it not only increases the inconvenience of product manufacturing, but also, if the load to be added is not missed in the manufacturing, the light emitting diode module 100 will be damaged immediately after being powered on, which will waste manufacturing materials and increase costs

Embodiment Construction

[0052] refer to Figure 4 , is a circuit diagram of the light emitting diode circuit assembly of the first embodiment of the present invention.

[0053]The LED circuit assembly 200 of the present invention includes a red / yellow LED (R / Y) 210 and a Zener diode (Zener Diode) 220 .

[0054] The red / yellow LED (R / Y) 210 has an anode 211 and a cathode 212 . The red / yellow LED (R / Y) 210 emits yellow-green light at 570 nanometers (nm) to red light at 660 nanometers (nm).

[0055] The Zener diode (ZD) 220 has an anode 221 and a cathode 222 . The anode 221 of the Zener diode 220 is connected to the cathode 212 of the red / yellow LED (R / Y).

[0056] In the light emitting diode circuit assembly 200 of the present invention, a Zener diode (Zener Diode) 220 and a red / yellow light emitting diode (R / Y) 210 are connected in series. Because the operating voltage (Vf) of a zener diode 220 is between 0.7V and 1.2V. Therefore, adding the operating voltage (1.8v to 2.6V) of the red / yellow LED ...

Abstract

The present invention discloses a light emitting diode circuit component which comprises a light emitting diode (LED) and a Zener diode, and the emission wavelength of the light emitting diode is between the 570nm yellow-green light to 660nm red light. The Zener diode is series-connected to the light emitting diode in order to increase the operating voltage of the light emitting diode and avoids the burnout by the instantaneous current.

Description

technical field [0001] The invention relates to a light-emitting diode circuit, in particular to a light-emitting diode circuit assembly which can prevent burning by instantaneous current. Background technique [0002] refer to figure 1 , is the protective circuit of general light-emitting diodes. [0003] refer to figure 2 , is the working curve of a general Zener diode. [0004] refer to figure 1 and figure 2 , generally used to protect the light-emitting diode (LED), usually using a Zener diode (Zener Diode) in parallel with the light-emitting diode (LED). Thereby, when the application circuit (not shown in the figure) of the light-emitting diode generates a reverse voltage V R or reverse current I R When, or when the general circuit generates static electricity (ESD), the Zener diode will be turned on immediately, so as to achieve the purpose of protecting the light emitting diode. [0005] Although the zener diode can protect the light-emitting diode, when the...
