Abstract
The invention relates to a LED light resource that using micro bulb as suppression resistance. Wherein, it uses serial micro bulbs in the LED (light emitting diode) circuit, to resist the current jump when the external voltage is increased, to make the increase of current less then the increase of voltage. And it is based on the character of tungsten filament that when in vacuum and the external voltage on its two ends increases, the resistance of tungsten filament will increase, to realize current increase with the voltage increase. The invention can avoid LED being broken down, to confirm its service life.
Description
Technical field:
The present invention relates to a kind of electric lighting.
Background technology:
Existing led light source, what adopt when using in illumination is directly to connect after the dividing potential drop with conventional, electric-resistance and LED, joins with external power supply again, keeps constant (thereby realization constant current), common prefix switch power supply in order to make the voltage in the input circuit.Because Switching Power Supply is higher with respect to cost each installation unit led light source of great majority, if directly join,, civil power makes that electric current increases in the circuit because rising at the voltage at night with civil power, can only be cost with the service life of sacrifice led light source.Therefore the led light source of existing series connection conventional, electric-resistance dividing potential drop exists defective.
Content of the present invention:
(the glass shell diameter is at Φ below 8 to the objective of the invention is to utilize pea lamp, vacuum tungsten light source that can be luminous), make in the circuit when external voltage runs into certain limit and raises (because of mains-supplied, 220V GB GB12325-2003 is defined as under the normal condition and allows-10% to+7% error, but when load was light at dead of night, the voltage of actual can measuring+20% raise) electric current that suppresses in the circuit rises to.According to the tungsten filament material under vacuum state, when external voltage raises, tungsten filament heating, its resistance along with the rising resistance of voltage near the characteristic that increases linearly, the rising of electric current in the circuit when effectively suppressing voltage and rising to.
Simultaneously, know that when the forward conduction of LED, this moment, the voltage at LED two ends was almost constant by the C-V characteristic of light emitting diode.Therefore, in the use of the led light source of series element, owing to be added in the voltage on the current-limiting resistance, V resistance=V the external world-∑ VLED, and ∑ VLED is almost steady state value, so increase part of external voltage, almost all be added on the resistance, when current-limiting resistance was conventional, electric-resistance, the electric current value of rising in the circuit will rising to greater than external voltage, electric current in the led light source circuit is sharply increased, thereby led light source was lost efficacy, and solution is that power input in light source is put a Switching Power Supply at present, makes entire circuit in constant voltage (thereby realizing constant current) work
The inventor finds that under study for action the led light source that it has been generally acknowledged that should be worked, and only in this way could guarantee the life-span of LED under DC voltage-stabilizing or constant current power supply state.This viewpoint is mistaken ideas on the understanding, descends the parameter of several keys to be no more than its limit in working order as long as can guarantee LED, just can not influence the life-span of LED.The main failure cause that the LED array light source uses out of doors, be because circuit board electrolysis after meeting the water excreting dampness makes due to its electrode destruction, therefore as long as carry out the reasonable parameter match selection between the two sealing in pea lamp and LED, and adopt the structure of hinge joint electrode immersed solder just can guarantee the service life of led light source.If adopting pea lamp to suppress electric current raises, in actual use, even rise at external voltage under 20% the situation, electric current increasing degree in the circuit only is about 15%, if without using mini-sized lamp as current-suppressing resistor, its electric current increasing degree will reach 30%, therefore adopt using mini-sized lamp as current-suppressing resistor, be not more than the service life that just can guarantee led light source at 20% o'clock in the external voltage increasing degree.According to pea lamp in enclosing, resistance and outer active line be the characteristic of linear growth almost, the inventor has proposed a kind of new led light source scheme with using mini-sized lamp as current-suppressing resistor, makes led light source under the prerequisite of lower cost, guarantees the convenience of its service life and installation.
Content characteristic of the present invention is: between the LED element, seal in pea lamp regular interval, can be when external voltage rise within the specific limits, electric current rises in the inhibition circuit, thereby avoid the puncture of LED when external input voltage rises within the specific limits, make light source fails.
Content of the present invention is further described with the following Examples.But content of the present invention is not limited to related content among the embodiment:
The principle schematic of the led light source among description of drawings: Fig. 1, the embodiment, Fig. 2 is the structural representation among the embodiment one, and Fig. 3 is the cutaway view Amplified image of A, and Fig. 4 is the structural representation of embodiment two, and Fig. 5 is the horizontal cutaway view Amplified image of Fig. 4.

Embodiment two:
As figure, 4, shown in 5, in the led light source assembly in the present embodiment, second lead-in conductor 1, pea lamp 2 and LED3, in first lead-in conductor 4 and second lead-in conductor 1 and the opaque plastics section bar 5, described first, the second source lead-in is coated or is embedded in the plastic material 5, pea lamp electrode 6 and the 7 hinge joint immersed solder of LED electrode, first, the second source lead-in is arranged along the profile length direction, in the illuminator group of serial connection, comprise that pea lamp 2 and LED3 form, pea lamp 2 and LED3 are placed on by regular interval in the hole of section bar punching out, and the other end of illuminator group links to each other with second lead-in conductor 1, thereby form a complete led light source unit.
