Abstract

The utility model discloses a light-emitting diode (LED) conducted by alternating current and free of stroboflash. Fluorescent powders are filled in the LED in the packaging process, and the fluorescent powders are silicate fluorescent powders. According to the LED conducted by the alternating current and free of the stroboflash, the packaging of the LED is modified, the method is simple, the number of simple fault points is small, the reliability is high, and the production cost is low. The LED is enabled to give out light constantly under the condition of alternating voltage, 80% of lightness can still be maintained when capacitance loses efficacy, the stroboflash is avoided, and the purpose of comfortable lighting is achieved.

Description

A kind of not LED of stroboscopic of conducting that exchanges

Technical field

The utility model relates to a kind of not LED of stroboscopic of conducting that exchanges, and belongs to the LED technical field.

Background technology

General LED need to adopt direct voltage drive, thereby usually adopts Switching Power Supply to reach the purpose that interchange is become the DC voltage driving LED.Therefore, in present LED light fixture, generally adopt Switching Power Supply power supply or RC induction to light a lamp.Adopt Switching Power Supply to increase production cost, price is high, and is subject to capacitor service life, at most only reaches 20,000 hours.

The Seoul, South Korea semiconductor adopts so-called interchange AC LED, then be with diode mode 4 string LED to be lighted in the mode of bridge rectifier, but the LED luminescent layer is very thin, is nanoscale, and is very limited to shock proof ability.And AC LED brightness meeting when exchanging the peak base obviously descends, and allows the people experience stroboscopic, and is uncomfortable.

The utility model content

Technical problem to be solved in the utility model provides a kind of not LED of stroboscopic of conducting that exchanges, can make under alternating voltage, and the LED capable of constant light emitting, stroboscopic not reaches the purpose of lighting.

For solving the problems of the technologies described above, the utility model provides a kind of not LED of stroboscopic of conducting that exchanges, and it is characterized in that, inserts fluorescent material in the LED encapsulation.

Described fluorescent material is silicate fluorescent powder.

Described LED encapsulation is parallel to the output of semiconductor rectifier bridge, and described semiconductor rectifier bridge is pulsating dc voltage with ac voltage rectifier.

The output of described semiconductor rectifier bridge is in parallel one electric capacity for energy storage simultaneously.

The LED that comprises a plurality of series connection in the described LED encapsulation.

The beneficial effect that the utility model reaches:

Interchange conducting of the present utility model is the LED of stroboscopic not, and encapsulation improves to LED, and method is simple, and simple fault point is few, and reliability is high, and production cost is low; Make under alternating voltage, LED can capable of constant light emitting, still can keep 80% brightness during condenser failure, and stroboscopic not reaches the purpose of lighting.

Description of drawings

Fig. 1 is the circuit diagram that exchanges conducting LED;

Fig. 2 is LED encapsulation schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As shown in Figure 1, the mode that exchanges conducting LED in the prior art is to utilize traditional semiconductor bridge-type rectification 1 that AC rectification is pulsating direct current, again with its output-parallel one capacitor C as energy storage, a plurality of LED2 in parallel so then can light LED2 safely simultaneously.But capacitor C is as supplying fully because of the very large space of needs, a-c cycle the lowest point, so be subject to the space, the utility model solution LED then is to be set about by LED encapsulation 3 without the method for stroboscopic, as shown in Figure 2, insert silicate fluorescent powder 4 in the LED encapsulation 3, silicate fluorescent powder 4 still can have a bit of time that twilight sunset is arranged after the outage energy disappears, and so just can reduce stroboscopic.

The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
