+
+<p>Os eventos de luz ambiente são uma maneira prática de tornar uma página da Web ou um aplicação ciente de qualquer alteração na intensidade da luz. Isto permite-lhes reagir a essa alteração, por exemplo, alterando o contraste da cor da interface do utilizador (IU) ou alterando a exposição necessária para tirar uma fotografia.</p>
+
+<h2 id="Eventos_de_Luz">Eventos de Luz</h2>
+
+<p>When the light sensor of a device detects a change in the light level, it notifies the browser of that change. When the browser gets such a notification, it fires a {{domxref("DeviceLightEvent")}} event that provides information about the exact light intensity.</p>
+
+<p>This event can be captured at the <code>window</code> object level by using the {{domxref("EventTarget.addEventListener","addEventListener")}} method (using the {{event("devicelight")}} event name) or by attaching an event handler to the {{domxref("window.ondevicelight")}} property.</p>
+
+<p>Once captured, the event object gives access to the light intensity expressed in <a href="http://en.wikipedia.org/wiki/Lux">lux</a> through the {{domxref("DeviceLightEvent.value")}} property.</p>
+
+<h2 id="Exemplo">Exemplo</h2>
+
+<pre class="brush: js">if ('ondevicelight' in window) {
+  window.addEventListener('devicelight', function(event) {
+    var body = document.querySelector('body');
+    if (event.value &lt; 50) {
+      body.classList.add('darklight');
+      body.classList.remove('brightlight');
+    } else {
+      body.classList.add('brightlight');
+      body.classList.remove('darklight');
+    }
+  });
+} else {
+  console.log('devicelight event not supported');
