Abstract
The utility model relates to an energy-saving LED (light-emitting diode) lighting lamp with high reliability and a long service life, which belongs to a semiconductor lighting lamp. The whole circuit comprises an LED constant-current power supply and a plurality of LED assemblies. One or a plurality of LED(s) are connected in series to form a group of LED light-emitting components, the two ends of each LED are respectively connected with a voltage stabilizing diode in parallel in opposite directions, and the LED assemblies are connected in parallel. When a large current occurs in the LED constant-current power supply for any reason, the voltage stabilizing diodes connected with the two ends of each LED in parallel cannot be impacted by the large current; and when an individual or multiple LED(s) is/are cut off during operation, other LED(s) can still operate normally, and the damage to the LED(s) caused by static electricity can be completely avoided.
Description
Technical field
The utility model relates to a kind of semi-conductor lighting lamp, especially a kind of LED energy-saving light of highly reliable extra long life.
Background technology
At present, existing LED lamp all unavoidably adopts several LED to be composed in series LED and forms a team or adopt the branch many again connection in series-parallel behind the bunchiness of only connecting, and in use, arbitrary LED lamp operating efficiency that all can make entire circuit that breaks down reduces.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of LED energy-saving light of highly reliable extra long life.
The technical scheme that its technical problem that solves the utility model adopts is: entire circuit is formed a team to constitute by LED constant-current supply and LED, one or several LED series connection, form one group of LED luminescence component, Zener diode of reverse parallel connection all at every LED two ends is organized the described LED parallel connection of forming a team more.When described LED constant-current supply inside big electric current occurs because of a variety of causes, the voltage-stabiliser tube of every LED two ends parallel connection can make it not be subjected to the impact of electric current this moment, simultaneously, at work if having indivedual or many LED when situations such as open circuit occurring, all the other LED of string can also operate as normal under it, and can thoroughly avoid the injury of static to LED.
The beneficial effects of the utility model are: entire circuit has improved the LED functional reliability greatly, prolongs the service life of LED under the thermolamp state.
Description of drawings
Accompanying drawing is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described further:
Light emitting diode can be chosen according to actual conditions, and Zener diode DW model is: 1418, and its voltage stabilizing value is chosen according to actual conditions.
