The lamp comprises an AC (alternating current) power source circuit and an LED module, and is also provided with a power source selector switch circuit module and a DC (direct current) standby power source circuit module; the LED module is simultaneously connected with a DC standby power source circuit and the AC power source circuit by the power source selector switch circuit module; and the DC standby power source circuit is connected with a storage battery. A charging circuit module for charging the storage battery is also connected in the AC power source circuit. By employing the design pattern above, the pulse charge can be automatically carried out on the storage battery in the case of supplying power to illumination; when the AC power source stops the power supply, the AC power supply can be switched to a module for power supply of the storage battery in time, and the power source is provided by the storage battery without manual operation and control; and furthermore, the LED lamp with the power source switching function also has the characteristic of low energy consumption, a light source with low electricity consumption is capable of saving about 50% of energy in the case of the same illumination, and the service life can reach above 10000 hours.
Description
Technical field
The utility model relates to a kind of lighting electric light source, specifically is a kind of LED lamp that has the back-up source power supply.
Background technology
So-called LED light fixture as its name suggests, is meant that the light fixture product adopts LED (Light-emitting Diode, light emitting diode) technology as main light emitting source.LED is a kind of solid-state semiconductor subassembly; It utilizes electric current forward to be passed to coupling place of semiconductor p-n knot; After mutually combining by the electronics of electronegative electronics that separates in the semiconductor and positively charged again; And the generation photo emissions, between different types of LED can send from the infrared ray to the blue light, and purple light to the light of different wave length such as between the ultraviolet ray.New development in recent years then is on blue-ray LED, to coat fluorescent material, and blue-ray LED is changed into the white light LEDs product.This operation generally needs collocation drive circuit (LED Driver) or power supply unit (Power Supply); The major function of drive circuit or power supply unit converts alternating voltage into dc source exactly; And accomplish the voltage and current be consistent with LED simultaneously, the assembly that matches with driving.
The bulb volume of LED light fixture is little, in light weight, and with epoxy encapsulation, can bear high-strength mechanical and impact and shake; Be difficult for fragmentation, and the brightness decay cycle is long, so be 50 its service life; 000-100 000 hour, far surpasses 1 of traditional osram lamp; 000 hour and fluorescent tube 10,000 hours.Because can reach 5～10 years the service life of LED light fixture; So not only can significantly reduce the cost of light fixture replacement; Has the speciality that minimum electric current gets final product driven for emitting lights because of it again; Under the situation of same illuminating effect, power consumption also has only 1/2nd of fluorescent tube, so LED also has power saving and energy-saving advantages simultaneously.But because the part technology of LED still dislikes not enough; So originally use the shortcoming on light fixture to comprise that light quality (color rendering, uniformity, colour temperature) is relatively poor, heat radiation is difficult and on the high side; And wherein heat radiation improperly then can cause the brightness of LED light fixture and circuit spare part to quicken to decay service life.Along with manufacturing technology advancing by leaps and bounds over past ten years, above-mentioned shortcoming comprises that the thermal resistance of LED reduces gradually, the light quality is also in lifting.2008, except the luminous efficiency of LED candoluminescence has reached 100 Lm/W, and the luminous efficiency of LED warm white was estimated also can be increased to 100 Lm/W from 70 present Lm/W in 2010.Compare with present other general light source, about 15 Lm/W of osram lamp, about 45～60 Lm/W of fluorescence fluorescent lamp, the luminous efficiency of LED is obviously gradually had an advantage.
Mostly existing LED light fixture is that constant-current supply drives, and does not possess the function that has outage to work on.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of LED lamp with power supply handoff functionality that has both the charge function of pulsing.
To achieve these goals, the technical scheme of the utility model employing is:
LED lamp with power supply handoff functionality; Comprise AC power circuit and led module; Also be provided with power change-over switch circuit module and dc standby power circuit module, said led module is connected with AC power circuit with the dc standby power circuit through the power change-over switch circuit module simultaneously; Said dc standby power circuit is connected with the accumulate pond.
Also be connected with in the said AC power circuit in order to give the charging circuit module of accumulate pond charging.
The beneficial effect of the utility model: owing to adopt above-mentioned design form, giving under the situation of illuminalive power-supply, can be to the charging of pulsing automatically of accumulate pond; When AC power is stopped power supply, can in time Alternating Current Power Supply be switched to battery-driven module, for it power supply is provided, not need manually-operated control by battery; In addition, the utility model also has the low characteristics of power consumption, but same light according under low power consumption light source energy savings nearly 50%, its life-span can reach more than 10,000 hours.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the electric theory diagram of the utility model.
Among the figure: 1, AC power circuit; 2, led module; 3, power change-over switch circuit module; 4, dc standby power circuit module; 5, accumulate pond; 6, charging circuit module.
The specific embodiment
As shown in Figure 1; LED lamp with power supply handoff functionality; Comprise AC power circuit 1 and led module 2; Also be provided with power change-over switch circuit module 3 and dc standby power circuit module 4, said led module 2 is connected with AC power circuit 1 with dc standby power circuit 4 through power change-over switch circuit module 3 simultaneously; Said dc standby power circuit 4 is connected with accumulate pond 5.Also be connected with in the AC power circuit 1 in order to give the charging circuit module 6 of accumulate pond 5 chargings.
