, for making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
For LED light source, the principle that improves the LED light source colour rendering is: after the spectrum to LED light source is analyzed, natural spectrum with reference to the Nature, supplement accordingly to spectrum that lack in LED light source or on the weak side, thereby reach the purpose that improves the LED light source colour rendering.
At present, the lighting angle of LED light source commonly used is generally 140 °, that is to say, the back of LED light source does not have light beam output.But, in the LED lighting device that often uses at present, not generally directly that LED light source is exposed at lighting device (for example, light fixture) in, but LED light source is arranged on a support, then this support is arranged on a substrate, the substrate that then will be provided with again LED light source is arranged on the surface of radiator, can also increase some accessories around LED light source subsequently, for example, optical lens, lampshade etc.The light transmittance of the accessory of these increases is generally all less than 1, therefore the part in the light beam exported of LED light source will be reflected back by above-mentioned accessory in the LED lighting device, and in the inside of this LED lighting device, constantly reflected, be reflected to the back of LED light source or inner other the surface of accessory of LED lighting device thereby likely have light.

Fig. 1 is the flow chart of method of the colour rendering of the raising light emitting diode illuminating apparatus in the utility model embodiment.As shown in Figure 1, the method for the colour rendering of the raising light emitting diode illuminating apparatus in the utility model embodiment comprises step as described below:
In specific embodiment of the utility model, be provided with the white LED light source module in the LED lighting device, be used for output white light beam (for example, can use red, green, blue three-color LED chip module combination results white light beam).This white LED light source module is arranged on light source module plate.
In this step, the surface of the non-source region on light source module plate is arranged one or more total reflection lens.Described total reflection lens, can be refracted to the incident ray of different incident directions the upper outgoing of same direction (for example, the parallel direction of the white light beam exported of white LED light source module).Therefore, after the surface of the non-source region on light source module plate arranges total reflection lens, can will all output to outside the LED lighting device at the light of all directions of LED lighting device internal reflection by set total reflection lens.
Better, in specific embodiment of the utility model, can according to the true form on the surface of the non-source region of light source module plate and at the angle and direction of the light of LED lighting device internal reflection, the concrete form of described total reflection lens be set.Concrete set-up mode does not repeat them here.
Better, in specific embodiment of the utility model, the non-source region of described light source module plate can comprise: do not arrange on the support in the LED lighting device on zone that support is not set on the zone, substrate of white LED light source module, radiator the zone of substrate and the zones such as sidewall of LED lighting device inside are not set.
Therefore, in preferred embodiment of the present utility model, described total reflection lens can be arranged on support any place or the many places in the sidewall of zone that substrate is not set on zone that support is not set on zone that the white LED light source module is not set, substrate, radiator and LED lighting device inside.
For example, due in the LED lighting device, the white LED light source module generally all is arranged on support, and, but the zone that the white LED light source module is not set on support is reflection ray also, belongs to the non-source region of described light source module plate, therefore in preferred embodiment of the present utility model, described total reflection lens can be arranged on support in the zone that the white LED light source module is not set, as shown in Figure 3.
Due in the LED lighting device, the support that is provided with the white LED light source module generally all is arranged on a substrate, but and also reflection ray of the zone that support is not set on this substrate, the non-source region that belongs to described light source module plate, therefore in preferred embodiment of the present utility model, described total reflection lens can be arranged on substrate in the zone that support is not set, as shown in Figure 4.
Due in the LED lighting device, be provided with the substrate operated by rotary motion of white LED light source module on radiator, and, but the zone that substrate is not set on radiator is reflection ray also, also belongs to the non-source region of described light source module plate, therefore, in preferred embodiment of the present utility model, described total reflection lens can be arranged on radiator in the zone that substrate is not set, and also can be arranged on substrate on zone that support is not set and radiator and not arrange in the zone of substrate, as shown in Figure 5.
Due in the LED lighting device, but the sidewall of LED lighting device inside is reflection rays all generally, the non-source region that also belongs to described light source module plate, therefore, in preferred embodiment of the present utility model, described total reflection lens can be arranged on the sidewall of described LED lighting device inside, as shown in Figure 6.
In the LED lighting device that can be used for throwing light on that uses at present, its light source is to use white LED light source/light source module mostly.Even and the highest white LED light source of light efficiency/light source module also has the characteristics of high color temperature (being generally 6500K) and low colour rendering (colour rendering index is 65-70).
As can be known, with the spectrum of natural daylight, compare after by experiment the spectrum of LED light source/light source module being analyzed, the spectrum of LED light source/light source module is mainly to have lacked the spectrum such as ruddiness, green-yellow light, ultraviolet light.Therefore,, for the LED lighting device,, as long as supplement the above-mentioned part spectrum that lacks or whole spectrum, can greatly improve the colour rendering of light source, make whole LED lighting device reach high-color rendering.
Because the white LED light source module in the LED lighting device can only be exported white light beam, therefore, in order to improve the colour rendering of LED lighting device, in this step, to apply on the surface of described total reflection lens one or more optical materials, this optical material can be used for the light of reflection specified wavelength.Wherein, different optical materials can be used for reflecting the light of different wave length.

For example, when the LED lighting device is during for normal room lighting, supplementary red-light spectrum only, thus in the colour rendering that improves the LED lighting device, reduce the infringement that the LED lighting device may cause the user.
And the LED lighting device is not for normal room lighting, but while being used for other occasion, can supplement any one or multiple spectrum in red-light spectrum, green-yellow light spectrum and ultraviolet spectra in the LED lighting device, thereby improve significantly the colour rendering of LED lighting device.
Therefore, better, in specific embodiment of the utility model, described specified wavelength can be: any one wavelength or multi-wavelength in the yellowish green light wavelength of the wavelength of the ruddiness of 620～780 nanometers, 500～600 nanometers, the ultraviolet light wavelength of 100～400 nanometers.
