[libgdx][box2dlights] Light renders "strange"

Newbie & Debugging Questions
#1

Hello guys.
I’ll keep it short. I think my problem is pretty obvious:

So, there are several problems. The light at the center is too bright and the light is shining through my player.
I tried nearly every config for the handler, but I can’t fix this issue.
Here is some code:

	public GameWorld() {
		world = new World(new Vector2(0, 0), false);
		
		RayHandler.setGammaCorrection(true);
		RayHandler.useDiffuseLight(true);
		handler = new RayHandler(world);
//		handler.setAmbientLight(0.2f, 0.2f, 0.2f, 1.f); The problem appears with ambient light, too.
		handler.setCulling(false);
//		handler.setShadows(true);
		handler.setBlurNum(1);

public void render() {
		Gdx.gl.glClearColor(0, 0, 0, 1);
		Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);	
		gw.update(Gdx.graphics.getDeltaTime());
		cam.update();
		cam.position.set(new Vector2(gw.player.getPosition().x,gw.player.getPosition().y),0);
		batch.setProjectionMatrix(cam.combined);
		batch.begin();
		//Render stuff
		batch.end();
		debugMatrix.set(cam.combined);
		debugMatrix.scale(BOX_WORLD_TO, BOX_WORLD_TO, 0);
		debugRenderer.render(gw.world, debugMatrix);
		gw.handler.setCombinedMatrix(debugMatrix, cam.position.x / BOX_WORLD_TO, cam.position.y / BOX_WORLD_TO, 800/BOX_WORLD_TO, 480/BOX_WORLD_TO);
		gw.handler.updateAndRender();
	}

Anyone some ideas, how this problem could be solved?
I’m sorry for my bad english.

Best regards,
