The smart way would be using a shit of light emitter material instead of a thousand LEDs... this is the trick mostly used to simulate lighting facades such as shopping or facades...
Based on your render engine there are different tips and tricks.
to have an overview of the technique please search :"apartment night texture"

Hi Majid that,s what I did, the LED's are octagons (red) which were made into light emitters. I am interested in what you thought the Led's were?
I completely understood you, you modeled all the lights and then replaced them with instances that does not produced remarkable saved time... am I right?
I mean a totally different approach, or sort of trick. the same trick that is used to simulate a fire: an image from fire flame ( that is also emitter) + an opacity mask..
You can mimic all the lights you have in a single texture like that and using the appropriate opacity mask, eliminate unnecessary parts and this way reduce emitter faces as much as possible... a bit tricky but time saving.
