Lighting apparatus with elastic unit to press power switch

A lighting apparatus, comprising:

• a top cover having an opening part for defining a light opening;
• a bottom cover, fixed to the top cover forming a containing space;
• a light passing cover having a larger diameter than the light opening, wherein a peripheral edge of the light passing cover engages an inner surface of the opening part of the top cover;
• a battery stored in the container space;
• a power circuit connected to the battery for providing a current to the LED modules of the light source plate;
• a power switch connected to the power circuit to control the LED modules, wherein the power switch is stored in the container space;
• a light source plate with a top side mounted with multiple LED modules, wherein the light source plate has a bottom side opposite to the top side, the bottom side is pressed by an elastic unit, when the light passing cover is pressed toward the light source plate, the light source plate presses and deforms the elastic unit to operate the power switch;
• and
• a clock unit, wherein the LED module of the light source plate emits a wakeup light when an alarm time is time up, wherein the light passing cover is pressed to turn off the wakeup light, wherein when the light passing cover is pressed, the clock unit waits by counting down a predetermined time period before turning off the wakeup light.
