LED is a light source, unlike energy-saving lamps or incandescent lamps currently on the market. SPOTLIGHT: As the name suggests it is a point of light emitted, and this point has both emit light also another important feature is that only one light up (back reflector for all conventional LED itself is no sense) . If we want to do with this particular light illumination, it must be some light on this process, we can meet our requirements and purpose, so we have to add optical design, to the relative concentration of point light sources becomes Astigmatism into a certain angle, which is the familiar straw hat LED, straw hat LED is a professional package for lighting design, on the one hand it allows the light from a central point source becomes loose angled light, on the other hand, it has fewer bad light effects, and allow more light transmission out of work for us.

Although the LED has a qualitative leap in the optical point of view, but we are familiar with the relative surface light source is concerned, it is still a point source, because the brightness is too concentrated, if human eyes look directly at the light source, or will our eyes cause some damage. Therefore, the LED lamps for home lighting, we will further be processed into the light, a further increase of the optical design, the human eye can achieve the purpose of observation, and soft light, but also on the other hand it is again amplified irradiation angle, although straw hat LED itself has done a range of 120 degrees, but if applied directly to home lighting, giving us the feeling that manifested on the roof is dark, we have to use lamps outermost transparent cover spread out the light again to accommodate normal household lighting.
