Member, every group of LED lamp bead unit include the LED lamp bead 1 of three series connection.
Soft light bar caused pressure drop circuit structure diagram on main line when Fig. 3 and Fig. 4 mainly retouches art low pressure 12V power supplies, mainly
Principle is：
1) due to for low-voltage power supply, very big pressure drop loss is produced there is impedance on main line, during to low-voltage power supply, can be with
It is longer circuit, electric current is bigger, and voltage becomes can be more and more lower, and this is also present conventional low soft light bar due to pressure drop
The reason for long can not be made, when light bar when by 12V low-voltage power supplies reaches 10 meters, voltage falls below 10.6V by original 12V
(assuming that the pressure drop of wire 13 is 0.2V), so due to supply voltage step-down, to every lamp bead on voltage there was only 2.5V, lamp bead
Normal working voltage by taking the 3V of routine as an example, such as when lamp bead voltage is 3V, because foregoing soft light bar is by flexibility
Wiring board produces, and radiating condition is poor, and power supply of such lamp bead on soft lamp becomes 20MA by the rated current of lamp bead for 60MA.When
When voltage becomes 10.6V by 12V, due to undertension, electric current is changed into 0MA, and such lamp bead does not light.
2) when conventional lights band is 5 meters, voltage also becomes 11V by original 12V.Then electric current can also be changed into 5MA, lamp bead brightness
It is dimmed.This results in the lamp bar brightness of input and light bar with darkness deepens behind during length increase, and brightness will not property.It can not make
With.
3) in Fig. 3, transformation current limiting component can allow input voltage to have a voltage range, when voltage becomes from the 12V of input
During 11V, output keeps 9V constant, and output current is at this moment adjusted cause 450MA, and (this electric current in an experiment, can allow temperature to keep not
Lamp bead is allowed to form big light inner feelings because of overheat), such luminosity is original 3 times, can not be accomplished so as to reaching existing lamp bar
Brightness.When input voltage becomes 10.6v, electric current can be dropped to 350mA by original 450mA, such brightness will not because of excessively dark,
And influence using effect.Linear quality such as main line is good, can accomplish 20 meters with low pressure soft light bar if line resistance is small, so fill up
There is very big leak on soft light bar uses on the market.That is, when high pressure soft light bar is used in interior decoration, although energy
Disposably 50 meters of long faces are drawn not have an error of light, but due to for uneasy full voltage, being deposited indoors during finishing and other uses
In unsafe factor, and belong to safe low-pressure lamp band and do not reached due to the line loss of main line voltage and do long purpose, such as
Do length and will divide and much break to realize, the power supply number so used is most also a lot, causes much to waste.
For light bar of the present utility model, when with low-voltage power supply, generally, the transformation current limiting component 8 is by three-terminal voltage-stabilizing
Device is formed, or is made up of the mixing of two triodes, so as to stablize the operating voltage shared in LED lamp bead, ensures whole light bar
On lamp bead can reach higher brightness effects.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in other related technologies
Field, similarly it is included in scope of patent protection of the present utility model.
