Abstract
The utility model discloses a light emitting diode (LED) lamp with color temperature capable of being adjusted, and belongs to the technical field of LED lamps. The LED lamp comprises a lamp body. A substrate is arranged inside the lamp body. The substrate is provided with an LED light source composed of a red-light module and a blue-light module which are in parallel connection. A circuit between the red-light module and an external power supply and a circuit between the blue-light module and the external power supply are respectively provided with a control switch. The LED lamp with the color temperature capable of being adjusted is reasonable in structure, convenient to use and good in effect, and is used for lighting indoors and outdoors.
Description
Technical field
The utility model relates to a kind of LED lamp, more particularly, relates in particular to a kind of LED lamp of adjustable color temperature.
Background technology
The appearance of blue-ray LED utilizes the combination of fluorophor and blue-ray LED, just can obtain white light LEDs easily, and this is a kind of white light packaged type the most ripe in the industry.White light LEDs has become lighting source at present, and general home lighting becomes a reality.The high-power product of conventional white light is to adopt the blue light wafer to excite single yellow fluorescent powder at present, and its shortcoming is that colour rendering is relatively poor; For improving colour rendering, in yellow fluorescent powder, to add red fluorescence powder usually and increase red composition in the spectrum, its shortcoming is because the conversion efficiency of red fluorescence powder is low, causes whole white-light emitting efficient to reduce.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of rational in infrastructure, easy to use and effect LED lamp of adjustable color temperature preferably is provided.
The technical scheme of the utility model is achieved in that a kind of LED lamp of adjustable color temperature; Comprise lamp body; In lamp body, be provided with substrate; Wherein said substrate is provided with led light source, and described led light source is made up of ruddiness module parallel with one another and blue light module, is respectively equipped with gauge tap on the circuit between ruddiness module and blue light module and the external power source.
In the LED lamp of above-mentioned adjustable color temperature, the peripheral lamp body of described led light source is provided with the silica gel layer that is mixed with yellow fluorescent powder.
In the LED lamp of above-mentioned adjustable color temperature, described ruddiness module is in series by three red diodes.
In the LED lamp of above-mentioned adjustable color temperature, described blue light module has two groups, and every group of blue light module is in series by three blue light diodes.
After the utility model adopts said structure, through in lamp body, setting up the ruddiness module, through regulating the mode of the red diodes electric current in the ruddiness module; Regulate the brightness of red diodes; Thereby reach the purpose of regulating colour temperature, and then realize the adjusting of LED lamp between different-colour, can adjust different colour temperatures according to the needs of different occasions; The conversion efficiency of having avoided adopting red light fluorescent powder and having occurred is low, the shortcoming that causes whole white-light emitting efficient to reduce.Has advantage simple in structure, easy to use.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view at A-A place among Fig. 1.
Among the figure: lamp body 1, substrate 2, ruddiness module 3, blue light module 4, silica gel layer 5.
The specific embodiment
Consult illustrated in figures 1 and 2ly, the LED lamp of a kind of adjustable color temperature of the utility model comprises lamp body 1; In lamp body 1, be provided with substrate 2; On substrate 2, be provided with led light source, described LED is made up of ruddiness module parallel with one another 3 and blue light module 4, is respectively equipped with gauge tap on the circuit between ruddiness module 3 and blue light module 4 and the external power source; On the lamp body 1 of led light source periphery, be provided with the silica gel layer 5 that is mixed with yellow fluorescent powder, yellow fluorescent powder helps color developing effect; Particularly, the ruddiness module 3 in the present embodiment is in series by three red diodes; Blue light module 4 has two groups, and every group of blue light module 4 is in series by three blue light diodes.
During concrete the use, as required,, can realize that light regulates between different-colour,, use convenient to adapt to the needs of different occasions through regulating the size of current of ruddiness module 3.
