Embodiment
A kind of embodiment of the present invention is described in detail with reference to Fig. 1.The illumination light module of the present embodiment
Including some first LED light sources 1, some second LED light sources 2 and control light part.In the present embodiment, the control light part is anti-
Emitter 3, the reflector 3 include some optical channels, some first walls for surrounding some optical channels and connection some first
Second wall of wall top edge, first LED light source 1 are arranged on the light inlet of the optical channel, and second LED light source is set
In on second wall.First LED light source 1 and second LED light source 2 are the different LED light sources of two kinds of colors, at this
In embodiment, first LED light source 1 is white LED light source, and second LED light source 2 is blue light LED light source.The control light
Part is used to control the light of first LED light source 1 in predetermined range of exposures, and second LED light source 2 is at least partly
Light is irradiated to beyond the predetermined range of exposures.As shown in figure 1, in the present embodiment, the control light part is the reflector
3, the reflector 3 controls the angle of emergence of the light of first LED light source 1 in the range of less than predetermined value, it is described go out
Angle of the firing angle between light and the optical axis b of first LED light source 1.It should be noted that the optical axis of so-called LED light source
Refer to the straight line at vertical and by LED light source the light-emitting area center with the light-emitting area of LED light source.Specifically, in the present embodiment
In, as shown in figure 1, the control light part is reflector 3, with optical axis b angle in the light that first LED light source 1 is sent
Light less than or equal to angle A can be directly emitted, this lightlike line such as light d and light h.In can directly be emitted described
In the light of one LED light source 1, light d and light h are the maximum light of the angle of emergence；And the angle with optical axis b is more than described in A
The light of first LED light source 1 becomes collimated ray outgoing, such as light a and light c, so, institute after reflector reflection
The maximum angle of emergence for stating the light of the first LED light source 1 is A, i.e., the light of described first LED light source 1 can only be irradiated to described
The optical axis b of first LED light source 1 angle is less than or equal in the range of angle A.So, in the present embodiment, the first LED
The predetermined range of exposures of light source 1 be using light d, light h as in the conical region on border, and beyond the conical region,
First LED light source 1 light irradiation less than.In the present embodiment, the predetermined value A is 30 °.And second LED light
At least part light of source 2 can be irradiated to the region beyond above-mentioned conical region, in the present embodiment, second LED light source 2
The larger LED light source of range of exposures is selected so that the light of second LED light source 2 can be irradiated to beyond above-mentioned conical region
Region, and allow the light of second LED light source 2 to be emitted naturally, i.e., artificially do not change its irradiating angle and direction, this
Sample, at least part light of the second LED light source 2 can be irradiated to the region beyond above-mentioned conical region, for example, in this implementation
In example, the light e and light g in wide-angle direction can be irradiated to the region beyond above-mentioned conical region.The reflector 3 is minute surface
Reflector, such reflector have stronger directionality to the reflex control of light, can be more effectively by light to predetermined party
To reflection.The total light flux of first LED light source 1 is more than 10 times of the total light flux of second LED light source 2, so,
In the predetermined range of exposures of first LED light source 1, the intensity of the light of first LED light source 1 is far longer than described second
The intensity of the light of LED light source 2, so, in the predetermined range of exposures, the color of light is mainly determined by first LED light source 1
It is fixed, Color influences very little of second LED light source 2 to light.In addition, in order that light more homogeneous soft, can be described
The light-emitting window of illumination light module sets diffusion part.Specifically, in the present embodiment, in the predetermined range of exposures, energy
The white light that mainly first LED light source 1 is sent seen；And beyond the predetermined range of exposures, it can be seen that described
The blue light that two LED light sources 2 are sent.
The light of first LED light source is controlled in predetermined range of exposures by using control light part, and described the
The light of two LED light sources can be irradiated to beyond the predetermined range of exposures, so, in different angles or different positions,
It can be seen that the illumination light module sends the light of different colours, and it is rich and varied, improve illumination aesthetic feeling.In addition,
In above-described embodiment, due to a control light part need not be set to be controlled the light of second LED light source, therefore structure
It is relatively simple.
As the simple deformation of the present embodiment, the control light part is lens, and the lens can select collimation lens, this
The light of first LED light source can be transformed into the beam projecting parallel with its optical axis by kind lens.Letter as the present embodiment
Monotropic shape, first LED light source are white LED light source, and second LED light source is red-light LED light source.
A kind of embodiment of the illuminator of the present invention is described in detail with reference to Fig. 2 to Fig. 4.The illuminating lamp
Tool includes shell 5, and the light-emitting window of the shell 5 is provided with diffusion shell 6.The illuminator also includes foregoing illumination light mould
