Abstract
The invention discloses an LED light source and a working method thereof. The light source comprises a disk, a lampshade, a singlechip, a control circuit, a small electromotor and a power supply, wherein the disk and the lampshade form a top-shaped lamp shell, an LED lamp group is inlaid on the disk, the LED lamp group comprises red LED lamps, yellow LED lamps and blue LED lamps, the singlechip, the control circuit, the small electromotor and the power supply are respectively installed in the lamp shell, and the singlechip is respectively connected with the LED lamps, the small electromotor and the power supply through the control circuit. In the invention, the singlechip is used for circuit control to respectively lighten the red LED lamps, the yellow LED lamps and the blue LED lamps which are inlaid on the disk. When the three colors of lamps are all lightened, white light with softer hue can be emitted. Brightness control is realized by controlling the rotating speed of the small electromotor. The on-off proportion of the LED lamps of different colors is controlled through the singlechip, thereby the hue of the emitted light can be continuously controlled.
Description
Technical field
The present invention relates to a kind of light source, particularly a kind of led light source and method of work thereof.
Background technology
Led light source determined that it is to replace the optimal light source of conventional light source owing to have following internal characteristics, it has purposes widely.
1, volume is little.LED is that a very little wafer is encapsulated in epoxy resin the inside basically, thus its very little, very light.
2, power consumption is low.The LED power consumption is very low, and in general the operating voltage of LED is that 2-3.6V, operating current are 0.02-0.03A.In other words: the electricity that it consumes is no more than 0.1W.
3, long service life.Under appropriate electric current and voltage, can reach 100,000 hours the service life of LED.
4, high brightness, low in calories.Than HID or incandescent lamp heat radiation still less.
5, environmental protection.LED is made by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and LED also can recycling simultaneously.
6, sturdy and durable.LED is encapsulated in the epoxy resin the inside completely, and it is all firmer than bulb and fluorescent tube.Also do not have loosening part in the lamp body, it is non-damageable that these characteristics make that LED can be described as.
7, controllability is strong.Can realize versicolor variation.
Led light source generally is monochromatic naughty light source, but for general illumination, people more need the light source of white.White LED light source adopts two kinds of methods to form usually, and first kind is to utilize the blue light technology to cooperate with fluorescent material to form white light; Second kind is multiple monochromatic light mixed method.These two kinds of methods all can successfully produce white light parts.First method produces white light, by GaM chip blue light-emitting (
) and YAG (yttrium-aluminium-garnet) fluorescent material be packaged together, when fluorescent material is subjected to send sodium yellow after blue-light excited, the result, blue light and yellow light mix form white light; Second method adopts the chip of different color light to be packaged together, and mixes producing white light by each coloured light.And be that the White LED light source that any method is made all has common shortcoming:
1, the white light colour temperature of Chan Shenging is higher, and tone is single, and white brightness is non-adjustable, and human eye is had bigger stimulation;
2, preparation white light process is very difficult.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the present invention will design and a kind ofly both can produce soft white light, can control the led light source and the method for work thereof of light-source brightness, color harmony color again.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of led light source, comprise disk, lampshade, single-chip microcomputer, control circuit, miniature motor and power supply, described disk and lampshade are formed a peg-top lamp housing, be inlaid with LED lamp group on the described disk, described LED lamp group comprises red LED lamp, yellow LED lamp and blue led lamp, described single-chip microcomputer, control circuit, miniature motor and power supply are installed in lamp housing inside respectively, and described single-chip microcomputer is connected with LED lamp, miniature motor and power supply respectively by control circuit.
Red LED lamp of the present invention, yellow LED lamp and blue led lamp respectively have 5 groups, radially install for every group, press red, yellow and blue order between group and the group along circumferentially installation.
A kind of method of work of led light source may further comprise the steps:
A, single-chip microcomputer light the red LED lamp, yellow LED lamp and the blue led lamp that are embedded on the disk by control circuit; When three kinds of colors all lighted, the disk of rotation can send the comparatively soft white light of tone;
The light on and off ratio of B, the LED lamp by the Single-chip Controlling different colours is come the luminous tone of continuous control;
C, control luminous brightness by the rotating speed of Single-chip Controlling miniature motor.
Compared with prior art, the present invention has following beneficial effect:
1, because the present invention adopts single-chip microcomputer to come control circuit, the red LED lamp, yellow LED lamp and the blue led lamp that are embedded on the disk are lighted respectively.When three kinds of colors all lighted, the gyro of rotation can send the comparatively soft white light of tone.
2,, can only realize brilliance control by the rotating speed of control miniature motor because the present invention is equipped with miniature motor.
3, because the present invention can be by bright, the ratio of going out of Single-chip Controlling LED modules with different colors lamp, thus but the luminous tone of continuous control.
4, because the present invention adopts single chip machine controlling circuit, therefore need not disconnecting circuit and more change the bulb and just can realize color control, not only make things convenient for but also attractive in appearance.
Description of drawings
2 in the total accompanying drawing of the present invention, wherein:
Fig. 1 is the led light source structural representation.
Fig. 2 is a led light source LED lamp group schematic layout pattern.
Among the figure: 1, disk, 2, single-chip microcomputer, 3, lampshade, 4, miniature motor, 5, control circuit, 6, power supply, 11, red LED lamp, 12, yellow LED lamp, 13, the blue led lamp.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.Shown in Fig. 1-2, a kind of led light source, comprise disk 1, lampshade 3, single-chip microcomputer 2, control circuit 5, miniature motor 4 and power supply 6, described disk 1 is formed a peg-top lamp housing with lampshade 3, be inlaid with LED lamp group on the described disk 1, described LED lamp group comprises red LED lamp 11, yellow LED lamp 12 and blue led lamp 13, described single-chip microcomputer 2, control circuit 5, miniature motor 4 and power supply 6 are installed in lamp housing inside respectively, and described single-chip microcomputer 2 is connected with LED lamp, miniature motor 4 and power supply 6 respectively by control circuit 5.Described red LED lamp 11, yellow LED lamp 12 and blue led lamp 13 respectively have 5 groups, radially install for every group, press red, yellow and blue order between group and the group along circumferentially installation.
