The three light-emitting diode groups are connected with the AT89S52 control chip, respectively, and the voltage stabilizer is also connected with the AT89S52 control chip. The AT89S52 control chip is also in parallel connection with two branch circuits, wherein the first branch circuit comprises a crystal oscillator and the second branch circuit is formed by a first capacitor and a second capacitor in serial connection. The node between the first capacitor and the second capacitor is grounded. The LED color-changing lamp of the utility model has the beneficial effects that proper lights can be adjusted according to different light sensitivity of different people, and thereby is more competitive among ornaments.

Description

The LED Color-changing lamp

Technical field

The utility model belongs to technical field of electronic equipment, is specifically related to a kind of LED Color-changing lamp.

Background technology

The LED Color-changing lamp is a kind of novel light bulb, and its profile is identical with general milky incandescent lamp bulb, but can send green grass or young crops, Huang, green, purple, blue, red, white light circularly automatically by the certain time interval variable color after lighting.It is applicable to family's birthday party, party in red-letter day, celebrates a festival the New Year, to adding happy atmosphere red-letter day, also can be used for public place of entertainment and makes advertising lamp etc. in one's power.Color-changing lamp is made up of red (R), green (G), blue (B) three-primary color LED.Dual-colored LED is that we are very familiar to, and generally is made up of red-light LED and green light LED, and it can send ruddiness or green glow separately, if ruddiness and green glow be simultaneously during bright spot, red green two kinds of light are mixed into orange-yellow.When three kinds of primary-color LEDs were lighted two LED respectively, it can send Huang, purple, cyan (sending purple light when lighting as red, blue two LED); If when three kinds of LED of red, green, blue lighted simultaneously, it can produce white light.If have circuit can make red, green, blue LED light in twos respectively, light separately and three-primary color LED is lighted simultaneously, the light that then can send seven kinds of different colours comes.

Summary of the invention

The purpose of this utility model provides a kind of LED Color-changing lamp, has solved the problem of LED Color-changing lamp variable color dullness in the prior art.

The technical solution adopted in the utility model is: a kind of LED Color-changing lamp comprises AT89S52 control chip, voltage-stablizer and led array; Described led array is made up of red light emitting diodes group, green LED group and blue LED group, and every group of light emitting diode group is composed in series by three light emitting diodes and a resistance; Voltage-stablizer is connected with led array, and three groups of light emitting diode groups are connected with the AT89S52 control chip respectively, and voltage-stablizer also is connected with the AT89S52 control chip; The AT89S52 control chip also is parallel with two branch roads, and first branch road is a crystal oscillator, and second branch road is first electric capacity and second electric capacity of series connection, the node ground connection between first electric capacity and second electric capacity.

The beneficial effects of the utility model are according to different people the difference of the sensitiveness of light to be accessed suitable light, make this lamp more have superiority in decoration.
