It should be noted that PET glue film 21 can also be the PET film of other colors, and the thickness and light transmittance of PET film 21
It can also voluntarily select according to actual needs, as long as guaranteeing that the irradiation nonuniformity of the light through glass table top 102 meets user
Demand.
In this example embodiment, as shown in figure 5, the solar simulator includes long pulse solar simulator, it is described equal
Even property component 2 includes silver-colored lac varnish 22, and the silver lac varnish 22 is sprayed at the second target area of the filter glass 103, described
Second target area is increased described in third preset area on second predeterminable area on the basis of the second predeterminable area
Silver-colored lac varnish 22, and/or, the region after the silver-colored lac varnish 22 of the 4th preset area of shearing.
Wherein, solar simulator at this time is long pulse solar simulator, then corresponding luminous source component 101 is long pulse
The source component that shines is rushed, the second predeterminable area is the area that the light of the luminous source component sending of long pulse is radiated on filter glass 103
Domain, the second predeterminable area are identical as the first predeterminable area；Third preset area and the 4th preset area are to be empirically derived
Area, or the area obtained according to homogeneity test.
It is exemplary, silver-colored lac varnish 22 easy to clean is fitted into paint spraying apparatus, then by paint spraying apparatus in filter glass 103
The second predeterminable area on spray silver-colored lac varnish 22, specific second predeterminable area needs is being filtered according to the transmitting of source component 101 that shines
Light-emitting surface on glass 103 determines that the light that source component 101 emits that needs to guarantee to shine is incident on silver-colored lac varnish 22, in addition, also
The requirement according to user to the irradiation nonuniformity of the light through glass table top 102 is needed to adjust silver-colored lac varnish 22 in filter glass
It position on 103 can be in order to guarantee that the irradiation nonuniformity of the light through glass table top 102 meets user demand
Part silver lac varnish is wiped out on the silver-colored lac varnish 22 sprayed, that is, wipes out the silver-colored lac varnish of the 4th preset area, or
Increase the silver-colored lac varnish in part on the basis of silver-colored lac varnish 22 through having sprayed, that is, increases the silver-colored lac varnish of third preset area, or
The silver-colored lac varnish of the silver-colored lac varnish in erasing part and increase part on the silver-colored lac varnish 22 sprayed simultaneously, that is, increase third simultaneously
The silver-colored lac varnish of preset area and the silver-colored lac varnish for wiping out the 4th preset area, so that the spoke of the light finally through glass table top 102
Meet user demand according to unevenness；For example, the spray area of silver-colored lac varnish 22 to be covered to section of entire light emitting source and lampshade in advance
Face simultaneously forms ellipse, then carries out increasing silver-colored lac varnish on the basis of this ellipse area or wipes silver-colored lac varnish.
It should be noted that uniformity component 2 can also be good for other uniformities, and light transmittance meets user demand
Paint, the present embodiment do not limit this.
In this example embodiment, the solar simulator includes short pulse solar simulator, and the uniformity component 2 wraps
