The specific embodiment
Below in conjunction with Fig. 1, a kind of embodiment of the present utility model is elaborated.The illumination light of the present embodiment is learned module and is comprised the first LED light source 1, the second LED light source 2 and control light parts.In the present embodiment, described control light parts are reflector 3, and described reflector 3 comprises optical channel and the wall that surrounds described optical channel, and described the first LED light source 1 is arranged on the light inlet of described optical channel.Described the first LED light source 1 is two kinds of LED light sources that color is different with described the second LED light source 2, and in the present embodiment, described the first LED light source 1 is white LED light source, and described the second LED light source 2 is blue-ray LED light source.Described control light parts are for being controlled at the light of described the first LED light source 1 in predetermined range of exposures, and at least part of light of described the second LED light source 2 is irradiated to beyond this predetermined range of exposures.As shown in Figure 1, in the present embodiment, described control light parts are described reflector 3, and described reflector 3 is controlled at the angle of emergence of the light of described the first LED light source 1 in the scope that is less than predetermined value, and the described angle of emergence is the angle between light and the optical axis b of described the first LED light source 1.It should be noted that, it is vertical with the light-emitting area of LED light source and through the straight line at the light-emitting area center of LED light source that the optical axis of so-called LED light source refers to.Particularly, in the present embodiment, as shown in Figure 1, described control light parts are reflector 3, are less than or equal to the directly outgoing of light of angle A in the light that described the first LED light source 1 sends with the angle of optical axis b, and this lightlike line is as light d and light h.In the light of direct described first LED light source 1 of outgoing, light d and light h are the light of angle of emergence maximum; And the light that is greater than described the first LED light source 1 of A with the angle of optical axis b becomes collimated ray outgoing after described reflector reflection, for example light a and light c, like this, the maximum angle of emergence of the light of described the first LED light source 1 is A, and the angle that light of described the first LED light source 1 can only be irradiated to the optical axis b of described the first LED light source 1 is less than or equal in the scope of angle A.Like this, in the present embodiment, the described predetermined range of exposures of described the first LED light source 1 is for take in the conical region that light d, light h be border, and beyond this conical region, the light of described the first LED light source 1 irradiate less than.In the present embodiment, described predetermined value A is 30 °.And at least part of light of described the second LED light source 2 can be irradiated to above-mentioned conical region region in addition, in the present embodiment, described the second LED light source larger LED light source of 2 Selective irradiation scope is so that the light of described the second LED light source 2 can be irradiated to above-mentioned conical region region in addition, and allow the light nature outgoing of described the second LED light source 2, i.e. for a change its irradiating angle and direction of people not, like this, the at least part of light of described the second LED light source 2 can be irradiated to the region beyond above-mentioned conical region, for example, in the present embodiment, the light e of wide-angle direction and light g can be irradiated to the region beyond above-mentioned conical region.Described reflector 3 is specular reflector, and such reflector has stronger directionality to the reflex control of light, can more effectively light be reflected to predetermined direction.The total light flux of described the first LED light source 1 is the more than 10 times of total light flux of described the second LED light source 2, like this, in the predetermined range of exposures of described the first LED light source 1, the light intensity of described the first LED light source 1 is far longer than the light intensity of described the second LED light source 2, like this, in this predetermined range of exposures, the color of light is mainly by described the first LED light source 1 decision, and described the second LED light source 2 is very little on the color impact of light.In addition, in order to make light more evenly soft, can diffusion part be set at the light-emitting window of described illumination light module.Particularly, in the present embodiment, in described predetermined range of exposures, what can see is mainly the white light that described the first LED light source 1 sends; And beyond this predetermined range of exposures, can see the blue light that described the second LED light source 2 sends.
By utilization, controlling light parts is controlled at the light of described the first LED light source in predetermined range of exposures, and the light of described the second LED light source can be irradiated to beyond this predetermined range of exposures, like this, in different angles or different positions, can see that described illumination light module sends the light of different colours, rich and varied, promoted illumination aesthetic feeling.In addition, in the above-described embodiments, owing to without control light parts are set, the light of described the second LED light source being controlled, so structure is comparatively simple.
As the simple deformation of the present embodiment, described control light parts are lens, and described lens can be selected collimation lens, and this lens can be transformed into the light of described the first LED light source with the parallel beam projecting of its optical axis.As the simple deformation of the present embodiment, described the first LED light source is white LED light source, and described the second LED light source is red-light LED light source.
Below in conjunction with Fig. 2 to Fig. 4, a kind of embodiment of lighting of the present utility model is elaborated.Described lighting comprises shell 5, and the light-emitting window of described shell 5 is provided with diffusion shell 6.Described lighting also comprises aforesaid illumination light module, and certainly, in the lighting of the present embodiment, the quantity that described illumination light is learned module is a plurality of, and this illumination light is learned module and is arranged in described shell 5.
As the simple deformation of the present embodiment, the light-emitting window of described shell is not established diffusion shell, but a translucent cover is set.
By utilization, controlling light parts is controlled at the light of described the first LED light source in predetermined range of exposures, and the light of described the second LED light source can be irradiated to beyond this predetermined range of exposures, like this, in different angles or different positions, can see that described illumination light module sends the light of different colours, rich and varied, promoted illumination aesthetic feeling.
