Abstract
The utility model provides an improve circuit of LED light source subassembly reliability, its structure includes a plurality of LED granules, and this LED granule is connected in the circuit through the series-parallel mode. Compared with the prior art, the novel circuit for improving the reliability of the LED light source assembly has the advantages of being reasonable in design, simple in structure, ingenious in conception, convenient to use and the like, improves the reliability of the LED light source assembly on the basis of not increasing the cost, avoids the condition that the whole string of particles are extinguished due to the fact that a single LED particle is opened, improves the reliability of the light source assembly, and therefore has good popularization and use values.
Description
Technical field
The utility model relates to a kind of led light source assembly circuit, a kind of specifically circuit that improves the led light source assembly reliability.
Background technology
LED is as the new and effective light source of a kind of green, advantage such as it has, and volume is little, power consumption is low, long service life, thermal radiation are little, environmental protection.Along with the fast development of LED industry, the LED light fixture of more and more specifications comes out, and these light fixtures all are made up of one or more led light source assemblies.When forming light source assembly, unavoidably to carry out parallel connection, series connection to LED by a plurality of LED.Shown in accompanying drawing 1, existing led light source module is just taked first series connection, and then the mode of parallel connection; As long as a LED open circuit is in use arranged; All will cause whole string LED to extinguish, have a strong impact on the illumination of light source assembly, for this reason; Must study the protective circuit of simple and inexpensive, make this harmful effect reduce to bottom line.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of simple in structure, circuit of improving the led light source assembly reliability is provided.
The technical scheme of the utility model realizes by following mode, this a kind of circuit that improves the led light source assembly reliability, and its structure comprises some LED particles, this LED particle is connected in the circuit through the series-parallel connection mode.
Said series and parallel circuit is meant that wherein at least one LED particle series connection back forms A, forms B after at least two series circuit A parallel connection, and at least two circuit B are cascaded.
Said LED particle is installed on the aluminium base.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that a kind of circuit that improves the led light source assembly reliability of the utility model has is simple in structure, easy to use, be skillfully constructed through the mode of series-parallel connection, change the connected mode of LED; The existing simple parallelly connected connected mode in the back of series connection earlier; Be revised as the mode that connection in series-parallel mixes, need not increasing on the basis of any components and parts, promptly can reduce the harmful effect that causes whole string LED to extinguish because of certain LED open circuit greatly; On the basis that does not increase cost; Improved the reliability of led light source assembly, avoided taking place, improved the reliability of light source assembly because of the situation that whole string particle that single led particle open circuit causes extinguishes; Thereby, have good value for applications.
Description of drawings
Accompanying drawing 1 is the electrical block diagram of prior art.
Accompanying drawing 2 is electrical block diagrams of the utility model.
Embodiment
Below in conjunction with accompanying drawing a kind of circuit that improves the led light source assembly reliability of the utility model is done following the detailed description.
Shown in accompanying drawing 2; This a kind of circuit that improves the led light source assembly reliability, its structure comprises some LED particles, this LED particle is connected in the circuit through the series-parallel connection mode; Said series and parallel circuit is meant that wherein at least one LED particle series connection back forms A; Form B after at least two series circuit A parallel connection, at least two circuit B are cascaded, and said LED particle is installed on the aluminium base.
Shown in accompanying drawing 2, when one of them LED extinguishes, have only other two LED that connect with it to extinguish, the influence of led light source assembly is reduced greatly, thereby improved the reliability of led light source assembly.
Claims (3)
1. a circuit that improves the led light source assembly reliability is characterized in that comprising some LED particles, and this LED particle is connected in the circuit through the series-parallel connection mode.
2. a kind of circuit that improves the led light source assembly reliability according to claim 1; It is characterized in that said series and parallel circuit is meant that wherein at least one LED particle series connection back forms A; Form B after at least two series circuit A parallel connection, at least two circuit B are cascaded.
