Member 221 corresponds, and light source unit 221 is arranged in the focus of lens unit, and lens unit is collected and collimated light source unit 221
The light of outgoing realizes illumination.
In the present embodiment, the second lens array 232 using being integrally formed, wrap by the center of the second lens array 232
Containing a hexagonal open structure 233, convenient for using the screwed lock cylindrical body, in other cases, the center of the second lens array 232
The open-celled structure 233 of position can be circle.
In actual use, such as Fig. 4 c, the second lens array 232 is spliced using four lens modules 234, is compared
In integrally formed second lens array, which is influenced smaller by stress, can prevent second
Lens array is burst apart due to thermal stress, extends light source life.
In the present embodiment, as shown in figure 5,240a bread of the lens carrier 240 close to 220 side of array of source contains support
Structure 242 and positioning column 243 are arranged and described previously consistent, and details are not described herein again；Lens carrier 240 is far from array of source
Four contour support levels 244 are arranged in the surrounding in the face 240b of 220 sides, are used to support and fix the second lens array 232,
Silica gel can be used the second lens array 232 is fixed on support level 244, screw etc. can also be used the second lens array
232 locks are paid each in each second lens 232a and the first lens array 231 on support level 244, making in the second lens array 232
231a is arranged in a one-to-one correspondence.With the above arrangement, lens group 230 at any position between light source 220 at a distance from it is identical, shine
The light efficiency of bright device is higher, obtains high-power illumination light.
Preferably, the face 140b (light-emitting surface) of lens carrier is coated with reflective coating (not shown), which is
Aluminium layer or silver layer can form reflective coating in the face lens carrier 140b using modes such as magnetron sputtering or chemical vapor depositions, should
Reflective coating can reflect the ambient light focused on lens carrier, avoid lens carrier poly- due to the radiations heat energy of ambient light
Collection, temperature rise.
In application, the light of array of source outgoing is collected through lens group, not will form a branch of ideal directional light after collimation,
But the light beam with certain dispersion angle is formed, therefore even if setting for light source unit is reduced at any position in array of source
It sets, will not influence the brightness of the emergent light of lighting device, the pattern of uniformity and illumination light, but lens carrier can be increased
On the one hand the flexibility of design, the application are made by the way that at least one support construction is arranged between lens carrier and array of source
The relative position obtained between lens carrier and substrate is more fixed, reliably；On the other hand it is formed between lens carrier and substrate
Heat dissipation path enables the heat on lens carrier to conduct in time to substrate and radiates, reduce lighting device internal heat, prevents
Only lens carrier and lens array deform and burst apart since lens carrier temperature is excessively high, and it is easily-deformable to solve lens carrier
And/or lens array to burst apart the problem of, and convenient for fixed lens carrier.
It is different from the prior art, by the way that at least one is arranged between lens carrier and array of source in the embodiment of the present application
Support construction is fixed the relative position between lens carrier and substrate more, reliably；On the other hand lens are formed
Heat dissipation path between bracket and substrate enables the heat on lens carrier to conduct in time to substrate and radiates, reduces and shine
Bright device internal heat prevents lens carrier deformation or lens array from bursting apart.
In addition, the second lens array is spliced using multiple lens modules in the embodiment of the present application, relative to entirety
Molding second lens array, central area are influenced smaller by stress, can prevent lens array from sending out due to thermal stress
Life is burst apart.
Moreover, lens carrier far from the side of light source is coated with reflective coating in the embodiment of the present application, it can reflect and focus on
Ambient light on lens carrier avoids lens carrier since the radiations heat energy of ambient light is assembled, and temperature rises, and aggravates lens carrier
Deformation or lens array burst apart.
