Abstract
The utility model discloses a LED illumination source which comprises a printed circuit board, a plurality of LEDs and a plurality of voltage stabilizing diodes, wherein, the LEDs and voltage stabilizing diodes are all installed on the printed circuit board and each LED is connected in parallel with one voltage stabilizing diode, which forms an uninterruptible power supply protective structure and a voltage stabilizing structure. If one of the LEDs is damaged and the circuit is broken, the voltage stabilizing diode connected in parallel with the LED is conducted to connect the circuit, thereby preventing from affecting the normal work of other LEDs which is connected in series with the damaged LED; while if the working voltage is over high, the voltage stabilizing diodes may be broken-down to protect the LEDs and avoid damages to the LED.
Description
[technical field]
The utility model relates to a kind of lighting device, refers in particular to a kind of LED lighting source.
[background technology]
Along with people are more and more higher to the requirement of environmental protection illumination, LED lighting source with plurality of advantages such as low energy consumption, high light efficiency, long service life replaces traditional fluorescent lighting light source and incandescent lighting light source gradually, and begins to be widely used in indoor and outdoor lighting.Common LED lighting source reaches a plurality of LED that directly is installed on the circuit board in mode in parallel or series connection by a circuit board and is constituted, as the disclosed patent No. of State Intellectual Property Office is that ZL200520019728.5, the patent No. are 200520002000.1 utility model patent document, all describes the LED lighting source of this class formation.The LED lighting source of said structure lacks the not structure of power-off protection, and the some LED on circuit board damage, and form outage condition, thereby other LED that cause being connected in series with this damage LED influence illuminating effect also along with extinguishing.In addition, the LED lighting source of said structure also lacks structure of voltage regulation, and set LED damages when input voltage is too high easily.
[summary of the invention]
The purpose of this utility model is to overcome the existing defective of common LED lighting source, and a kind of not LED lighting source of power-off protection structure and structure of voltage regulation that has is provided.
The purpose of this utility model is achieved in that a kind of LED lighting source, include a printed circuit board and be installed on a plurality of LED that electrically connect with series connection or in parallel or series connection and the mode that combines in parallel on the described printed circuit board, its improvement is, described LED lighting source also includes a plurality of Zener diodes that are installed on the described printed circuit board, and each described LED is connected in parallel into a described Zener diode is arranged.
In the above-mentioned LED lighting source, described LED and described Zener diode are divided into the two sides of described printed circuit board.
Than common LED lighting source, the beneficial effects of the utility model are: being connected in parallel in each LED constitutes the not power-off protection structure and the structure of voltage regulation of LED lighting source into a Zener diode, when wherein a certain LED damages and when forming off state, but Bing Lian Zener diode conducting and play the effect of communication line with it, thereby do not influence the operate as normal of other LED that connect with this damage LED; And when operating voltage was too high, Zener breakdown can take place and play the effect of protecting LED in Zener diode, avoided damaging LED.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the surface structure schematic diagram of the utility model LED lighting source.
Fig. 2 is the decomposition texture schematic diagram of the utility model LED lighting source.
Fig. 3 is the circuit connection diagram of the utility model LED lighting source.
[specific embodiment]
Referring to figs. 1 to shown in Figure 3, LED lighting source disclosed in the utility model comprises a printed circuit board 10, a plurality of LED20 and a plurality of Zener diode 30, wherein, described LED20, Zener diode 30 all are installed on the described printed circuit board (PCB) 10, and each LED20 is connected in parallel into a Zener diode 30.In the present embodiment, LED20 adopts series connection to be connected with the mode that combines in parallel, and promptly a plurality of LED20 are serially connected in the LED string earlier, and a plurality of LED string connects in parallel again, really, also can adopt series connection or mode in parallel to connect.
In order to reduce the size of made printed circuit board 10, LED20 and Zener diode 30 should be divided into the two sides of printed circuit board 10.
Be connected in parallel in each LED and constitute the not power-off protection structure and the structure of voltage regulation of the utility model LED lighting source into a Zener diode, when wherein a certain LED damages and when forming off state, but Bing Lian Zener diode conducting and play the effect of communication line with it, thereby do not influence the operate as normal of other LED that connect with this damage LED; And when operating voltage was too high, Zener breakdown can take place and play the effect of protecting LED in Zener diode, avoided damaging LED.
