Emergency Lighting. WHAT ARE THE CODES?
You could refer NFPA 110 (Standard for Emergency and Standby Power Systems) and *BS:5266 - 1 (Emergency lighting - Part 1: Code of practice for the emergency lighting of premises).
*BS: 5266 - 1, standard is to promote wider understanding of the different types of emergency lighting system which may be employed, and to give guidance on their correct application to the varied requirements of different categories of premises.
Not exactly clear on what you're asking. NFPA 101 would tell you when they're required and the minimum illumination for the occupancy you are covering.
when are they need. I was told if you have backup lites on ceiling then the lites are not need at doors
As has been stated in a few posts, it's not one standard for every potential building use. Some occupancies don't need any, some need them. Do you need them at the door? Maybe maybe not? Do the back-up lights meet the requirements to be emergency lights (come on with power failure and last the minimum time and provide the illumination required) and if so, do they illuminate the areas properly. I'm unaware of any standard that say they have to be at the door, but I'm sure that wherever they're mounted they must provide illumination of the complete path of egress, so...
IBC 1006.1, NFPA 101 Sections 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, and 22.214.171.124, NFPA 70 Article 517.63, NFPA 110, NFPA 111, NFPA 99 depending on the facility and local codes. Which year is critical because not all jurisdictions are enforcing the latest versions. Consult with the AHJ.
One of the governing codes is NFPA 101, Life safety Code.
One has to determine the Structure/Building occupancy then proceed to that specific chapter to ascertain the required
level of illumination [ Both during "normal" power and "emergency"]. ie, New and Business Occupancies fall under
Chapters 38/39; 38.2.8 [39.2.8] which in turn then references one to proceed to Section 7.8 [Illumination of means of
egress] and Section 7.9 [Emergency lighting].
Note: the Sections 7.8 and 7.9 are common to all occupancy types with different levels/requirements based on the
One other Illumination Standards is the Illuminating Society Engineering of North America lighting reference manuals.
These standards not only indicate where to apply the requested lighting but also set minimum and/or recommended
Illumination levels [ Footcandles, etc.]

NFPA Life Safety Code 101 is the recognized reference for emergency lighting. You can also find emergency egress markings / emergency lighting for buildings over 75ft from fire department access.
