Description

A kind of Multifunctional LED luminaire

Technical field

The utility model relates to a kind of LED luminaire, the particularly a kind of Multifunctional LED luminaire that can regulate colour temperature, colour rendering simultaneously and carry out color transformation.

Background technology

Light emitting diode (LED:Light Emitting Diode) is the semiconductor photoelectric device that emerges rapidly in recent years, it has that volume is little, in light weight, power saving, life-span are long, advantages such as brightness height and luminescence response speed are fast, easy and transistor and the supporting use of integrated circuit.Along with improving constantly of chip light emitting efficient, LED has also obtained application to a certain degree in the general illumination field.Compare with conventional lighting source such as fluorescent lamp, incandescent lamp, the LED luminaire by the color LED chip of collocation red, green, blue, can also be realized color lighting except that realizing the white-light illuminating.In addition, for white light LEDs, under high luminance relay tender feeling condition, light efficiency and colour rendering are higher, but under low colour temperature, colour rendering is poor, the requirement of color deviation general illumination.By adding ruddiness, green light LED chip, except realizing color lighting,, can improve the colour rendering of light source and the colour temperature of adjusting light source by red, green light colour mixture with white light.Realize ordinary light source or the simple inaccessiable illuminating effect of white LED light source.

Summary of the invention

The purpose of this utility model provides a kind of Multifunctional LED luminaire, and when realizing the common white optical illumination, it is colored adjustable to realize that colour temperature, colour rendering can be in harmonious proportion.The utility model is suitable as the general illumination light source, and in colour rendering, color is rich and aspect such as environmental protection is better than conventional fluorescent lamps and three-color fluorescent lamp again, and is huge in the application prospect of general illumination.

The concrete technical scheme that the utility model adopted is: a kind of Multifunctional LED luminaire, by red, green, the led chip group that blue-light LED chip is formed, White-light LED chip more than one or two, base and drive circuit are formed, it is characterized in that: red, green, the led chip group that blue-light LED chip is formed is installed in the center of base, White-light LED chip more than one or two is installed on the base, and be evenly distributed on around the led chip group, drive circuit is by the power input mouth, control circuit, the dc output end mouth is formed, the power input mouth is connected with external power source, control circuit respectively with power input mouth and dc output end mouth, the dc output end mouth is connected with each led chip.Control circuit can be bought from the market and obtain.

The White-light LED chip of selection more than one or two is as conventional lighting source, and the led chip group that configuration red, green, blue led chip is formed by control circuit, is regulated the luminous intensity of three-primary color LED chip and White-light LED chip.By the colour mixture of three primary colours light and white light, reach following effect: the white light that 1, obtains different-colour.2, obtain the colourama of different saturation.3, obtain the white light of high-color rendering.

The center that is arranged in base of the led chip group that described red, green, blue led chip is formed also keeps chip close as far as possible under nonoverlapping situation.

Described White-light LED chip be evenly arranged in led chip group that the red, green, blue led chip forms around.

The beneficial effects of the utility model are: because the blue light that blue-light LED chip sends, the ruddiness that red LED chip sends, the green glow that the green light LED chip sends, form polychromatic light, the light that sends with White-light LED chip carries out colour mixture, the light intensity by changing three coloured light and the light intensity of white light can be made different illuminating effects by same LED luminaire, comprising: the White LED with high color rendering property lamp of different-colour; The color LED lamp of different saturation.This white LED lamp in the scope of colour temperature 2500K-6500K, the light efficiency height, colour rendering is good, the life-span is long, is suitable as the general illumination light source.This lighting has conventional fluorescent lamps and the not available color lighting effect of three-color fluorescent lamp again simultaneously, has the wide application prospect of replace fluorescent lamps.
