Abstract
The utility model relates to an LED flash lamp circuit. A bridge type rectification voltage-stabilized source is respectively connected with one ends of a plurality of green LED lamps, red LED lamps and blue LED lamps, wherein the green LED lamps, the red LED lamps and the blue LED lamps are connected in series; and the other ends of the green LED lamps, the red LED lamps and the blue LED lamps in the series connection are respectively connected to an LED controller. According to the utility model, the technical effects of the LED flash lamp circuit are as follows: after the power is connected, the green LED lamps, the red LED lamps and the blue LED lamps are lightened successively and then the all lamps are lightened together; and the lights with the three kinds of colors are combined into white lights that can be used at night conveniently, so that the toy pleasure is increased; and the product cost is saved.
Description
Technical field
The utility model relates to a kind of circuit, relates in particular to a kind of LED flash lamp circuit.
Background technology
A lot of toys on the market wherein utilize LED to make relatively being favored of toy now, and are particularly varicolored luminous, all are solid colors but LED is luminous at present, can not be with the light compositing white light of different colours.
Summary of the invention
The purpose of this utility model is to provide a kind of LED flash lamp circuit, and this technology is mainly used in making on the various toys, can send green, redness and blue and synthetic white light on the toy, is convenient to toy and uses night, improves added value of product.
The utility model is to realize like this, it comprises bridge rectifier stabilized voltage power supply, green LED lamp, red LED lamp, blue led lamp, led controller, it is characterized in that the bridge rectifier stabilized voltage power supply connects an end of the green LED lamp of several series connection, red LED lamp and blue led lamp respectively, the other end of the green LED lamp after the series connection, red LED lamp and blue led lamp is connected led controller respectively.
The preferred 74LS90 of described led controller.
Technique effect of the present utility model is: after connecting power supply, and green LED lamp, red LED lamp, the blue led lamp is successively bright, and then bright together, and the light compositing white light of three kinds of colors is convenient to use night, increases toy enjoyment, saves production cost.
Description of drawings
Fig. 1 is fundamental diagram of the present utility model.
Bridge rectifier stabilized voltage power supply 2, green LED lamp 3, red LED lamp 4, blue led lamp 5, led controller in the drawings, 1.
Embodiment
As shown in Figure 1, the utility model is to realize like this, bridge rectifier stabilized voltage power supply 1 connects an end of green LED lamp 2, red LED lamp 3 and the blue led lamp 4 of several series connection respectively, and the other end of the green LED lamp 2 after the series connection, red LED lamp 3 and blue led lamp 4 is connected led controller 5 respectively.After the circuit connection, through the voltage of bridge rectifier stabilized voltage power supply 1 output 15V, voltage is powered to three row's light-emitting diodes, as 74LS90 difference Rg, and Rr, during Rb end output low level, so Dui Ying green light is bright, red colored lamp is bright and blue lamp is bright.When three ends are low level entirely, synthetic emitting white light then.
Fig. 1 is LED flash lamp circuit connection layout.Green light is a row, and red colored lamp is a row, and blue lamp is a row, and a row is four high-brightness LED light-emitting diodes, and three rows are arranged in parallel.The forward end of luminous tube links together, and receives bridge rectifier stabilized voltage power supply end, and bridge rectifier stabilized voltage power supply end output 15V voltage is for three row's light-emitting diode practicalities.The negative pole end of luminous tube is received Rg respectively, Rr, and Rb three ends, three ports are got involved led controller 74LS90, and the 74LS90 counter is exported three kinds of low levels respectively.
Claims (2)
