The 24-year-old, who joined the club from Benfica in January last year, has helped the Blues to the Champions League and FA Cup semi-finals this term.
And the Brazilian says that he hopes this success can continue, despite the added workload of English football.
"I want to play important games, semi-finals in the FA Cup and the Champions League," he told reporters.
"In England and the Premier League you play more games but I like it.
"I'm 24 years old, I have my health and want to play football every day. I love football and love playing big games."
The defender also expressed delight at clocking up his 50th appearance for the club during Saturday's 2-1 win over Wigan.
He added: "I am happy because it is fantastic to play for Chelsea and 50 games in one year is so good.
"This league is so difficult, injuries are always possible but I am happy to play so many games.
"To start the season injured is hard, the other guys have more fitness and preparation so it was difficult but now we are the same and I am happy with my body."
The defender, born in Sao Paulo, has been involved in every Blues' game since Boxing Day and has therefore had to adapt to the cold English weather.
Despite this, Luiz revealed that he likes living in London, saying: "It's not like Brazil but now the weather is fantastic and not so cold.
"All the people tell me it's good weather, we had only two days of snow. I like it here in London."
The centre-back has gained a reputation for going on individual runs from the back, sometimes surrendering possession in compromising positions.
And, whilst he admitted he likes to get forward when he can to score goals, he insisted that stopping the team from conceding is his main focus.
"I try and want more [goals]," he added.
"All the players in the world, whether defenders or strikers, like to score but my mentality on the pitch is first of all defending and then if it's possible I can help the guys in attack.
"I scored against Man United two times, I scored against Man City, I scored two similar goals against Bayer Leverkusen and Bolton so for me all the goals are important."
