Color LED lamp
Technical field
The present invention relates to a kind of color LED lamp.
Background technology
Known color LED lamp system carries out power supply proportioning with red bluish-green primaries, the object of adjusting to reach color change and brightness.Its weak point is: this sample loading mode has brightness not and the shortcoming of darker in color.
Summary of the invention
The object of this invention is to provide a kind of red bluish-green white proportioning mode that uses, be aided with suitable LED position configuration, improve the brightness in lamp source, simultaneously because of the increase of brightness, improve the color LED lamp of lamp source color rendering.
Technical solution of the present invention is described color LED lamp, comprise that the lamp housing of built-in R, G, B, W tetra-color light source and light source condenser assembly, described lamp housing mouth end are provided with the euphotic cover of built-in secondary optical lens, its special character is: described R, G, B, W tetra-color light source are distributed on the lamp plate of geometrical configuration line.
As preferably: the light source condenser sheet that described light source condenser sheet assembly is buckled on described each light source by some adjacent R, G, B three-color light source and cover forms.
As preferably: by some adjacent R, G, B three-color light source and cover cap, the dimpling shape eyeglass on described each light source and connection plane that each dimpling shape eyeglass is connected as a single entity form described light source condenser sheet assembly.
As preferably: described R, G, B, W tetra-look LED light sources are distributed on the lamp plate of rectangular line.
As preferably: described R, G, B, G LED light source are distributed on the lamp plate of rectangle line.
As preferably: described R, G, B, W tetra-look LED light sources are distributed on the lamp plate of annular concentric line.
As preferably: described R, G, G, B LED light source are distributed on the lamp plate of annular concentric line.
As preferably: described R, G, B, W tetra-look LED light sources are distributed on the lamp plate of five-pointed star line.
As preferably: described R, G, B, W tetra-look LED light sources are distributed on the lamp plate of triangle line.
As preferably: described R, G, B, W tetra-look LED light sources are distributed on the lamp plate of ordinate, horizontal line or L line.
Compared with prior art, beneficial effect of the present invention:
When the projectional angle of LED lamp as shown in Figure 8 from known 1200 narrow down to this color LED lamp 80~600 time, obvious, the brightness of LED is the trend increasing substantially.Thereby this color LED lamp has improved the brightness in lamp source, because of the increase of brightness, also improved the color rendering in lamp source simultaneously.
(2) this color LED lamp R+G+B+W combination of light sources as shown in Figure 9 and R+G+B+G combination of light sources as shown in figure 10, its brightness cannot be apparently higher than known R+G+B combination of light sources.
