AttributeError: module 'custom_components.light' has no attribute 'setup'

I have no other custom_component.
This is my code:

import logging

import voluptuous as vol

# Import the device class from the component that you want to support
from homeassistant.components.light import ATTR_BRIGHTNESS, Light, PLATFORM_SCHEMA
from homeassistant.const import CONF_NAME
import homeassistant.helpers.config_validation as cv
import pyCIP.CIP as cip

_LOGGER = logging.getLogger(__name__)

CONF_SENDER_ID = 'sender_id'

PLATFORM_SCHEMA = PLATFORM_SCHEMA.extend({
    vol.Required(CONF_SENDER_ID): vol.All(cv.ensure_list, [vol.Coerce(int)]),
    vol.Required(CONF_NAME): cv.string,
})

def setup_platform(hass, config, add_devices, discovery_info=None):
    """Setup the Crestron Light platform."""

    sender_id = config.get(CONF_SENDER_ID)
    lightname = config.get(CONF_NAME)
    # Add devices
    add_devices([CrestronLight(sender_id, lightname)])



class CrestronLight(cip.CIPHandler, Light):

    def __init__(self, sender_id, lightname):

        self._lightname = lightname

    @property

        return self._lightname

    @property

        return self._on_state

    def turn_on(self, **kwargs):

        """
        cip.CIPHandler.send_buttonpress(0x80ac)
        #self._light.turn_on()

        cip.CIPHandler.send_buttonpress(0x80ac)
        #self._light.turn_off()

    def update(self):
