W: Hello, Raman. I've heard you were asking to order lunch for our training session.

M: Yes. I have two prices and I'm not sure which one to choose.

W: OK.

M: The first one is from Rainbow Cafe, which is $300. And the delivery is free.

W: They're just in High Street, aren't they?

M: That's right. The other price is $260, from Lunch Box. But you have to pay delivery and that's $5. So that makes it a total of $280.

M: OK. Let's order from Rainbow Cafe.

W: Do you have the telephone number?

M: Yes. It's 8571395. Ah, no, that's the number of Lunch Box. Rainbow Cafe is 8489632. I'll call them now.

【题目】目前有些居民区内楼道灯的控制，使用的是一种延时开关。该延时开关的简化原理如图所示。图中D是红色发光二极管（只要有很小的电流通过就能使其发出红色亮光），R为限流电阻，K为按钮式开关，虚线框内S表示延时开关电路，当按下K接通电路瞬间，延时开关触发，相当于S闭合，这时释放K后，延时开关S约在1 min后断开，电灯熄灭。根据上述信息和原理图，我们可推断：

按钮开关K按下前，发光二极管是________（填“发光的”或“熄灭的”），按钮开关K按下再释放后，电灯L发光持续时间约________min。这一过程中发光二极管是________。限流电阻R的阻值和灯丝电阻RL相比，应满足R________RL的条件。
