Abstract
The utility model relates to a lighting electric appliance which applies mini-bulbs in series (incandescent lamp type light source) in LED (light emitting diode) circuit to check the rising current along with the voltage in circuit when the outside voltage rises within uncontrollable range. The utility model is characterized in that the LED (light emitting diode) circuit is provided with mini-bulbs in series and luminnophor groups formed by mini-bulbs and the LED (light emitting diodes) in series connection at regular intervals which are in parallel connection with two electrodes of the power supply electrode holder, thus preventing the LED (light emitting diodes) from the over current breakdown when the voltage rises within certain range.
Description
Technical field:
The utility model 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.
The utility model content:
The purpose of the utility model content is to utilize pea lamp (the glass shell diameter is at Φ below 8, 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 are defined as under the normal condition and allow-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
I find 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 hinged 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 the certain voltage scope, 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.
The feature of the utility model content 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.
The utility model content 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, Fig. 3 is the cutaway view Amplified image of A.
The specific embodiment:
Embodiment 1: shown in Fig. 2,3, have lucite pipe 1, pea lamp 2, LED3, first lead-in conductor 4, second lead-in conductor 5 in the led light source assembly in the present embodiment, bulb or LED seat 6, first, second power supply lead-in conductor is arranged along the length direction of tube wall in the described pipe 1, the illuminator group of serial connection is made up of pea lamp 2, LED3, be placed in the lucite pipe pea lamp and LED3 regular interval, the other end of illuminator group links to each other with lead-in conductor, thereby forms a complete led light source unit.
