first i am very thankful to you for reply , you are totally awesome , again thanks for joining xpiera ray forum (i have seen all your posts , so helpful)
I have tried , but still not working
Lemme explore it
Once i have CM7 installed , i go to settings and set brightness to full
then use my device it works good
After i lock it and open it again i find brightness it reduced to half
i go to settings and check it , it shows brightness is set to full but in reality it is not
is there any problem with my bootloader unlocking method ?

It may be a problem with cm7, have you asked in the cm7 thread ?
The brightness works on my the miui roms
Not sure why it doesnt on cm7 so may be rom specific so report on that thread and see if you get any feedback. it may be a known bug

My miui has tweaks for smoothness and extended settings but try them all.
Overclocking does use battery so undervolt as well, undervolting is trial and error to see if your phone remains stable
Overclocking to high could damage the phone if used over a prolonged period of time I would imagine but a quick google search will get you more info

i solved this problem
i used this thread http://forum.xda-developers.com/showthread.php?t=1377125
change the same part in hw_config.sh(inside system/etc)
to：
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds/
echo 0,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 12900 > $dev/torch/max_current

As far as I know you have to change "echo 0,0,0,0" to "echo 3,2,2,0"

i had this problem to solved using this guide! if is not working with the file edit, use the als_curve.ini (backup first)

I have this in CM 7
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,65,255,24,24,5,128 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current
Last time i changed the whole code , now i think i have to only change
echo 2,0,0,0 TO echo 0,0,0,0
right ?

i replaced lights.semc.so with stock lights.semc.so file , in system/lib/hw
brightness works but only problem is LED light always turn on , in pink color

That's right, only change the "echo x,x,x,x" phrase.
I tried "echo 3,2,2,0" and "echo 1.5,1,0.5,0 30h". I dont realy know what these parameters exaktly mean, but "echo 1.5,1,0.5,0 30h" works fine on my ray.
You also can change your als_curve.ini in system/etc.

Do you mean the flash LED on the back? And does it keep the brightness you set before you locked?

Hello xutienan9520,
could you please explain me the difference between
"echo x.x.x.x" and "echo x.x.x.x.x.x.x", i`m noob as f**k.
And what kind of effect does "echo 0.0.0.0.0.0.0" have to your brightness?

i also dont know about this , changing above echo to 0,0,0,0,0,0,0 fixed my issue
Change this
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 1,65,255,24,24,5,128 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current
TO
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds
echo 0,0,0,0,0,0,0 > $dev/lcd-backlight/als/curve # ALS curve for group1
echo 2,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
