Detailed description of the invention
For making the object, technical solutions and advantages of the present invention of greater clarity, below in conjunction with specific embodiment party
Formula referring to the drawings, the present invention is described in more detail.It should be understood that these describe the most exemplary,
And it is not intended to limit the scope of the present invention.
Structural representation according to embodiments of the present invention shown in the drawings.These figures are not to paint in proportion
System, the most for purposes of clarity, it is exaggerated some details, and some details may be eliminated.Figure
Shown in various regions, component shape and the relative size between them, position relationship be only example
Property, reality is likely to be due to manufacturing tolerance or technical limitations and deviation, and those skilled in the art
According to actually required can additionally design, there are the region/parts of difformity, size, relative position.
Fig. 1 shows a kind of colour temperature adjustment structure of LED light device in prior art.
In the colour temperature adjustment structure of the prior art shown in Fig. 1, main employing circuit control and regulation colour temperature
Scheme.As it is shown in figure 1, LED light device includes LED light source 500, drive circuit 400, diffuser

The wall 203 that is in the light, be used for limiting described light-emitting zone 202, the wall 202 that is in the light uses light-proof material to constitute,
The function that having shuts out the light passes through.In the present invention, LED light source preferably uses blue light LED light source, but
The present invention is not restricted to this, it would however also be possible to employ the LED light source of other colors.
As shown in Figure 8, diffuser 4 is provided with two or more color temperature regions 404, for realizing at least
The colour temperature regulation of more than two kinds.Specifically, along the week of each described color temperature regions 404 on diffuser 4
Length is provided with lighttight shading limit 403, is provided with identical or different color in each described color temperature regions 404
The fluorescent material of temperature value, with the regulation colour temperature by the light of this color temperature regions.Preferably, each two is adjacent
Color temperature regions 404 arranges the fluorescent material of different-colour value.
In an embodiment of the present invention, described color temperature regions 404 be shaped so as to can cover correspondence send out
Light region 202, to guarantee that the light that light-emitting zone 202 sends can be all by corresponding color temperature regions 404.
Preferably, the multiple color temperature regions 404 on diffuser 4 are formed as along being longitudinally continuous distribution and having phase similar shape
The rectangular area of shape.
Such as, in the embodiment shown in fig. 8, shading limit 403 limits rectangle color temperature regions 404, thus
Diffuser 4 is divided into multiple such rectangle color temperature regions, each color temperature regions 404 is provided with difference
The plurality of color temperature value such as the fluorescent material of colour temperature, such as 3000k, 4500k, 6000k.
In said structure, shading limit 403 uses light-proof material to constitute, the merit that having shuts out the light passes through
Can, scatter to the color temperature regions on side for blocking the light in the color temperature regions of place to such an extent as to cause the most homochromy
Mixed light between temperature area.
Although it is not shown, the LED light device of the present embodiment necessarily includes drive circuit, for LED light
Source provides and drives electric current to make it luminous.Unlike first embodiment, diffuser support 5 in the present embodiment
On conducting terminal 501 be arranged to the LED light source that is electrically connected on light-emitting zone 202 all the time.Such as,
But the present invention is not restricted to this, electricity can be set in the side corresponding with conducting terminal 501 of LED lamp panel 2
