    LED lighting two optical design, in general, LED light source's own light angle and intensity distribution can not meet the characteristics of the application conditions, it is necessary to carry out two of light distribution to change the light source output, to achieve practical application requirements.Indoor Lighting

     Two primary effects of optical design are usually the following three types: dispersion: The light from the LED source is dispersed to form a larger angle to form a more uniform spot (such as a ceiling lamp, a direct TV backlight lens, etc.) in the receiving screen. Convergence: The LED light source to a smaller range of light, to improve the center of luminous intensity (such as projection lights, stage lights, etc.). Lighting is carried out with a certain light distribution curve, so that the light flux directly to the working face is not more than 10% of the total light pass when the face boundary is not considered.Indoor Lighting

    There are a wide range of classification methods for lighting lamps, such as classification according to use, according to CIE recommended by the luminous flux distribution ratio classification and according to dust, moisture, electric shock grade classification. Among them, by the use of classification. Semi-direct type lamps (Simi-direct lighting luminaire) This type of lamps most of the luminous flux ($number) to the lower hemisphere space, a small part of the above, fired on the upper component will reduce the lighting environment produced by the shadow of the hardness and improve its tables.Indoor Lighting

    Diffuse or direct-indirect luminaires (diffused lighting luminaire) lamps have almost the same luminous flux (40%-60%). The most common is the milky white glass spherical lampshade, the other various shapes diffuse translucent light of the closed lampshade also has a similar distribution. This luminaire places light evenly in all directions, so the light flux utilization is low. The luminaire is down to 10%-40%, and its downward component is often used only to produce a brightness commensurate with the ceiling, too much or improper distribution will produce some defects, such as direct or indirect glare.Indoor Lighting
