Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the present invention provides a kind of LED illumination module, including LED light source group 10,20 and of wavelength conversion layer
Reflector 30, the LED light source group 10 and wavelength conversion layer 20 are located inside the reflector 30, and along the opening of reflector 30
Direction is bonded setting successively, and the side of the wavelength conversion layer 20 is located at the focal point of reflector 30, and wavelength conversion layer 20 is remote
One side from LED light source group 10 is equipped with total reflection layer 40.Specifically, the light that LED light source group 10 is emitted projects wavelength convert
On layer 20, since one side of the wavelength conversion layer 20 away from LED light source group 10 is equipped with total reflection layer 40, through wavelength conversion layer 20
Internal wavelength convert it is particle excitated go out light be finally emitted from the side of wavelength conversion layer 20, and after the reflection of reflector 30
Outgoing forms illuminating bundle, and wavelength conversion layer 20 is phosphor powder layer, and close and away from LED light source group 10 face is much larger than side
Face, i.e., it is long and wide much larger than height, usually 10 times or more of difference when wavelength conversion layer 20 is rectangular parallelepiped structure, work as wavelength convert
When layer 20 is cylindrical structure, the diameter of upper bottom surface is much larger than height, usually 10 times or more of difference, therefore by the present invention in that light
Line is emitted from the side of wavelength conversion layer 20, is greatly reduced the area in beam projecting face, is improved the brightness of exit facet.This
Outside, it is necessary to which explanation, the side of wavelength conversion layer 20 is located at the focal point of reflector 30, is equivalent to each of reflector 30
The opposite central axes of point outwards translate a distance, which is equal to the half of 20 section of wavelength conversion layer and grows or half-breadth or radius, this
When focus have multiple and form a rectangle or circle.Light in figure is only schematic diagram, and under actual conditions, light is not exhausted
To exiting parallel, some light can be emitted from intermediate vacancy, so as to form uniform illumination spot.
Preferably, the size of the wavelength conversion layer 20 is not less than the size of the LED light source group 10.That is wavelength conversion layer
20 can cover LED light source group 10, ensure that the light that LED light source group 10 is sent can be all projected on wavelength conversion layer 20.
As shown in Fig. 2, the LED light source group 10 includes several LED chips 110, several LED chips 110 are arranged in

110 quantity of LED chip is 9, along the quadrate array of long and cross direction difference arrangement form 3*3, at this point, wavelength conversion layer 20
For cube structure, light is emitted from four sides therein.The quantity of certain LED chip 110 can be more or less, this
Place does not limit.
As shown in figure 3, the LED light source group 10 includes several LED chips 110, several LED chips 110 are arranged in
Circle, the section of the wavelength conversion layer 20 are the circle being adapted with the shape of the LED light source group 10.I.e. multiple LED cores
Piece 110 corresponds to a phosphor powder layer, without being separately provided phosphor powder layer for each LED chip 110, simplifies structure, and makes
More convenient, in Fig. 3, the quantity of LED chip 110 is 8, be arranged in it is approximate circle, at this point, wavelength conversion layer 20 is cylinder
Structure, light is emitted for one week from side, so as to form circular light spot.The quantity of certain LED chip 110 can be more or less,
It does not limit herein.
As shown in figure 4, a heat-conducting layer 50 is equipped between the LED light source group 10 and wavelength conversion layer 20, for by wavelength
The heat that conversion layer 20 and LED light source group 10 generate quickly exports, and avoids 20 heat of wavelength conversion layer excessively high and impaired, described to lead
Thermosphere 50 transmits the light that LED light source group 10 is sent, the light that reflective wavelength-converting layer 20 inspires, the ruler of the heat-conducting layer 50
The very little size not less than the wavelength conversion layer 20, cooling fin (not shown) of the both ends on the outside of reflector 30,
Rapid cooling is carried out by cooling fin.Preferably, the heat-conducting layer 50 is made of glass or sapphire, in addition, heat-conducting layer 50
Optical thin film is coated with, the light that this film transmission LED light source group 10 is sent, the light that reflective wavelength-converting layer 20 inspires.
