Description
Technical field
Technical field of LED light illumination is the utility model is related to, is related specifically to a kind of lamp bead circuit of LED.
Background technology
LED is commonly called as light emitting diode, is a kind of solid-state semiconductor device that can convert electrical energy into visible ray, with phase
The continuous innovation of pass technology, LED extend to daily by application scenarios such as initial instrument and meter instruction light source, traffic lights
The every aspect of life, LED have the characteristics that energy-saving and environmental protection, service life are long, and its use brings extremely strong economic effect
Benefit and social benefit.
LED product of the prior art, circuit structure are to use some LED lamp beads being connected into one group mostly, or will
Parallel connection is done again after lamp bead series connection, so as to form the lighting part of whole LED.Above method can be avoided because of the damage of 1 lamp bead
The problem of badly influenceing whole LED illumination, but due to lacking the safeguard measure to LED lamp bead so that the lamp bead of LED is easy
Damage, and the damage of wherein 1 or several lamp beads can cause the uneven phenomenon of LED illumination appearance.A kind of therefore it provides energy
It is enough to be used in 1 or the damage of multiple lamp beads without influenceing LED, and can guarantee that the LED lamp bead circuit of uniform illumination just seems
It is very necessary.
Utility model content
Technical problem to be solved in the utility model is that LED lamp bead present in prior art is fragile, and 1 or several
The damage of individual lamp bead can cause LED illumination the problem of uneven occur.A kind of new LED lamp bead circuit structure, the LED are provided
There is lamp bead circuit current-limiting protection to lamp bead make it that LED lamp bead service life is longer, 1 or the damage of multiple lamp beads without
Influence LED to use, and can guarantee that the technical characterstic of uniform illumination.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows：
A kind of lamp bead circuit of LED, including at least two LED lamp bead set, the lamp bead set include at most 26
LED lamp bead group；The LED lamp bead group includes at least three LED lamp bead, 1 resistor, and each LED lamp bead connects with resistor in series
Connect；Each LED lamp bead group is connected in parallel to form LED lamp bead set, and each LED lamp bead set is connected in parallel.
Further：The LED lamp bead set includes 20~26 LED lamp bead groups.
Further：The LED lamp bead group includes 3~6 LED lamp beads.
Further：The resistance of the resistor is 300 ohm.
Further：The resistor string is coupled to LED lamp bead group power cathode end.
Further：When the LED lamp bead set is arranged on a printed circuit board, the LED lamp bead Cheng Zhi of each LED lamp bead group
Line arranges.
Further：The spaced arrangement of lamp bead group of each LED lamp bead set.
Therefore, the beneficial effects of the utility model have：
Effect one, the use of LED is not influenceed as wherein 1 or the damage of several lamp beads.
Effect two, by the setting of series resistance, improve the power of resisting voltaic impingement of LED.
Effect three, it is spaced by each LED light group of different LED lamp bead set, ensure that the uniform of LED light
Property.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Accompanying drawing 1 is circuit diagram of the present utility model.
Accompanying drawing 2 is the utility model printed circuit board arrangement schematic diagram.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this practicality
It is new, it is not used to limit the utility model.
Embodiment 1
As shown in figure 1, a kind of lamp bead circuit of LED, including at least two LED lamp bead set, the lamp bead set include
At most 26 LED lamp bead groups；The LED lamp bead group includes at least three LED lamp bead, 1 resistor, each LED lamp bead and resistor
It is connected in series；Each LED lamp bead group is connected in parallel to form LED lamp bead set, and each LED lamp bead set is connected in parallel.
The LED lamp bead set includes 20~26 LED lamp bead groups, and Fig. 1 show the LED that 2 LED lamp bead set are formed
Lamp bead circuit diagram, each LED lamp bead set include 26 LED lamp bead groups, and each LED lamp bead group includes the LED lamp bead of 3 series connection
With 1 resistor.
The resistor string is connected to LED lamp bead group power cathode end.
As shown in figure 1, the voltage in the LED lamp bead circuit between LED+ and LED- is DC12V, due to each LED lamp bead
Collection is combined into parallel-connection structure, therefore its magnitude of voltage is DC12V, when LED power is 10W, flows through the electricity of each LED lamp bead group
It is 300 ohm to flow for 16mA, resistance value, then it is 2.4V that each lamp bead, which gets voltage, it is assumed that wherein 1 LED lamp bead damage, LED
Lamp bead group quantity is changed into 25 from 26, then the electric current for flowing through remaining each LED lamp bead group is 16.64mA, if lamp bead group damage 5
It is individual, that to flow through the electric current of remaining each LED lamp bead group be 20.8mA, increase 4.8mA, and got voltage is constant, to remaining LED
The use of lamp bead will not influence too much.
As shown in Fig. 2 in order to ensure being uniformly distributed for light, reduce LED lamp bead damage and whole LED lamplight is evenly distributed
The influence of property, when the LED lamp bead set is arranged on a printed circuit board, the LED lamp bead of each LED lamp bead group is aligned,
The spaced arrangement of lamp bead group of each LED lamp bead set.
Although the illustrative embodiment of the utility model is described above, in order to the art
Technical staff is it will be appreciated that the utility model, but the utility model is not limited only to the scope of embodiment, to this technology
For the those of ordinary skill in field, as long as various change is in the utility model spirit that appended claim limits and determines
