Description

LED Mixed Lights Illumination light fixture

Technical field

The utility model belongs to field of semiconductor illumination, relates in particular to a kind of LED Mixed Lights Illumination light fixture.

Background technology

Along with the continuous ripe development of semiconductor technology, the LED fluorescent tube progressively replaces the first-selection that incandescent lamp becomes the household illuminating lamp source.Spectral line is narrow, luminosity is very suitable for mixed light use with forward current is approximated to direct ratio, response speed is fast and volume is little in operating voltage range because LED has.The method of the white light of LED lamp realization is at present promptly carried out mixed light with synthesize white light through the chip of red, green, blue three primary colours; But it is this bad through the synthetic white light light efficiency of three kinds of primary colours chip mixed lights; And in colour temperature is the scope of 2700K-6000K; Wavelength is that the ruddiness of 620-770nm lacks easily, causes colour rendering low, and color saturation is poor.

The utility model content

The utility model technical problem to be solved is that the LED Mixed Lights Illumination that a kind of light efficiency is better, colour rendering is high and color saturation is good light fixture is provided.

The purpose of the utility model mainly is achieved through following proposal: a kind of LED Mixed Lights Illumination light fixture; Comprise lamp holder, lamp housing and lampshade; Be provided with aluminium base in the said lamp housing; Be fixed with equally distributed several led chips along the aluminium base center on the said aluminium base, said led chip pin is through wire connecting power, and the mounted LEDs chip is the LED chip of difference red-emitting and white light on the said aluminium base; And two kinds of LED streets are provided with, and said lampshade inner surface scribbles latex powder.

Because colour temperature is in the scope of 2700K-6000K, wavelength is that the ruddiness of 620-770nm lacks easily, causes colour rendering low, and color saturation is poor.Therefore in the scheme of the utility model, the led chip of collocation red-emitting has so just remedied the deficiency that ruddiness lacks easily in the white light that is synthesized by three primary colours chip mixed light in the led chip of use emission white light; Two kinds of different LED streets are provided with; The light that sends mixes each other, scribbles the lampshade of latex powder then through the surface, makes the light efficiency of the light that lighting sends better; Colour rendering is higher, and color saturation is also better.

As preferably, the led chip of said emission white light and red-emitting is provided with the proportional spacing of number 2:1.Through test contrast, the light efficiency that the led chip of emission white light and the led chip of red-emitting send when being provided with the proportional spacing of number 2:1 is best.

As preferably, the led chip of said emission white light and the led chip of red-emitting all are circle distribution along the aluminium base center.Two kinds of different chips are circle distribution, gold-tinted and white light are fully mixed, and profile are more attractive in appearance.

As preferably, the number of the led chip of described emission white light is 4, and the number of the led chip of red-emitting is 2.

As preferably, described aluminium base bottom is provided with the heat conduction silicon chip, and the size and the aluminium base of described heat conduction silicon chip are complementary.Be provided with the heat conduction silicon chip makes and the utlity model has better radiating effect in the aluminium base bottom.

As preferably, described aluminium base and heat conduction silicon chip are circle.General LED lamp is sphere, and aluminium base and heat conduction silicon chip are circle, helps installing.

Therefore, it is better to the utlity model has light efficiency, and colour rendering is high, the characteristics that color saturation is good.

Fig. 1 is the utility model structural representation;

Fig. 2 is a distribution schematic diagram of launching the led chip of white light and ruddiness on the aluminium base.

The specific embodiment

A kind of LED Mixed Lights Illumination light fixture, as shown in Figure 1, comprise lamp holder 1, lamp housing 2 and lampshade 3, be provided with circular aluminium base 4 in the said lamp housing 2, aluminium base 4 bottoms are provided with the circular heat conduction silicon chip 5 that is complementary with aluminium base 4.As shown in Figure 2; Be fixed with 6 led chips that are circularly and evenly distributed along aluminium base 4 centers on the aluminium base 4; The led chip 7 of the led chip 6 that these 6 led chips are 4 red-emittings and 2 emission white lights; And the led chip 7 of emission white light and the led chip 6 of red-emitting are provided with the proportional spacing of number 2:1, and the led chip pin is through wire connecting power, and said lampshade 3 inner surfaces scribble latex powder.

Because colour temperature is in the scope of 2700K-6000K, wavelength is that the ruddiness of 620-770nm lacks easily, causes colour rendering low, and color saturation is poor.Therefore in the scheme of the utility model, the led chip 6 of collocation red-emitting has so just remedied the deficiency that ruddiness lacks easily in the white light that is synthesized by three primary colours chip mixed light in the led chip 7 of use emission white light; And two kinds of different LED streets are provided with; The light that sends mixes each other, scribbles the lampshade 3 of latex powder then through the surface, makes the light efficiency of the light that lighting sends better; Colour rendering is higher, and color saturation is also better.And through overtesting contrast, the light efficiency that the led chip of emission white light and the led chip of red-emitting send when being provided with the proportional spacing of number 2:1 is best.

Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should understand in addition; After the content of having read the utility model instruction; Those skilled in the art can do various changes or modification to the number and the spread geometry of the led chip of led chip and the red-emitting of emission white light on the aluminium base in the utility model, and these equivalent form of values fall within the application's appended claims institute restricted portion equally.
