which light set can show "ambient()" of shader mixer (builder) ? (3delight)

Hi,
by DAZ shader mixer document
http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/interface/panes/shader_mixer/bricks/dzambientbrick/start
and 3delgiht shader document , I think daz default material blick circulate ambient

Diffuse color * (Ambient( ) +Ambient color) * Ambient Strength.

"ambient ( )" is same as shader builder function "Ambient" (or shader mixer Ambient blick) out put value.
document say, "total amount of ambient light incident upon the surface"

then,, my question is not about how to decouple diffuse , (I could with switch, )
but want to know how "Ambient() " work with type of light. and light option., scene setting,,

I tweaked ds default material shader, and separate,"Ambient() "and "Ambient color" effect.
because I hope to use "Ambient color" as "self glow" color, (not effected by Ambient light etc,,)
then use "ambient()" as real ambient light color of surface.

my surface shader "Ambient " section is like that,,

(Ambient() * Ambient light Strength* Ambient light Color) + (selfAmbient Color * selfAmbient strength)

(both have switch to couple or decouple diffuse color )

when I set selfAmbient Color , or selfAmbient strength= black or zero,
and remove diffuse or specular eftect by setting each property value as zero,

it return,
"Ambient() * Ambient light Strength* Ambient light Color"
(Amb light color may not need, but I added it to control more flexible)

then I set Ambient light Strength = 100% Ambient light Color = (255, 255, 255),

it should only show the color of "total amount of ambient light incident upon the surface" =Ambient()

it work well, but I can only see "Ambient()" effect, when I make Ambient light from shader mixer, or builder ,,,like my pic.
I hope to use it with other light set ^^;

then which light set of daz product, and option can show the Ambient() (light effect) for me?

I thought uber enviroment 2 light GI or ID mode may work,, but I can not clear see effect,,

then what type of light (product) count Ambient() of surface (removed "ambient color" effect )?
and what need ,if I make light , to set scene to see the Ambient() effect?

eg I test with daz offered, shader builder DzAmbientLight,, but it have too many option ^^;
then I can not clear,, which setting is good to see the light "Ambient()" only,,

apply "daz default mat shader",on plane

set shader porperties,
diffuse color= white, diffuse strength = 0%, specular color = black, ambient color = black, ambeint strength= 100%
it may only show Ambient() (caused by ambient light )on the surface. ( ambient color= black)

usually most of light just show plane as black,
(daz disant light, daz directional light, daz point light,spot light etc,,,)
= no ambient

but If I make " base light" made by shader mixer, then set color of light , it eliminate the plane with light color.
and it change with Ambient strength of plane.

3delight User manual,> The shadding language> Function said,,,

color ambient ( )
Returns the contribution from ambient lights. A light is considered ambient if it does not
contain an illuminate() or solar() statement. It is not available in lightsource shaders.

but I do not know clear,, which light (or option) can work as same as base light ?
eg AoA ambient light work same?
which light not contain an illuminate( ) or solar()?
