PROCESSES AND CATAYLSTS FOR THE SELECTIVE HYDROGENATION OF COMPOUNDS HAVING CARBONYL CARBON ATOMS

Selective hydrogenation processes are disclosed that can upgrade impure feeds, such as those obtained from biomass and containing a number of small (e.g., 2-6 carbon atom) molecules having aldehyde and/or ketone carbon atoms.

A backlight module includes a reflection base plate, at least one light source, at least one 3D optical control structure and a reflector. The light source is disposed on the reflection base plate. The 3D optical control structure is disposed on the reflection base plate and covers the light source. The 3D optical control structure includes a top surface and a lateral connected to the top surface. The lateral obliquely faces toward the reflection base plate, and an acute angle exists between the lateral and the reflection base plate. The reflector is disposed on the reflection base plate and beside the lateral. Light emitted from the light source passes through or is reflected by the top surface or the lateral, wherein a part of light passing through the lateral is reflected by the reflector so as to transmit toward a direction away from the reflection base plate. 1. A backlight module , comprising:a reflection base plate;at least one light source, disposed on the reflection base plate;at least one 3D optical control structure, disposed on the reflection base plate and covering the at least one light source, each 3D optical control structure comprising a top surface and a lateral connected to the top surface, wherein the lateral obliquely faces toward the reflection base plate, and an acute angle a is formed between the lateral and the reflection base plate; anda reflector, disposed on the reflection base plate and beside the lateral of the at least one 3D optical control structure, wherein light emitted from each light source passes through the top surface or the lateral of the corresponding 3D optical control structure, or is reflected by the top surface or the lateral, wherein a part of light passing through the lateral is reflected by the reflector so as to transmit toward a direction away from the reflection base plate.2. The backlight module according to claim 1 , wherein a base angle of the reflector contacting with the reflection base plate is an acute angle ...

LIGHT SOURCE MODULE

Alight source module includes a substrate, multiple light sources disposed on the substrate, and multiple three-dimensional optical control structures located above the light sources. Each optical control structure includes a top portion disposed corresponding to the light source and has multiple top light transmissive patterns, a first side portion, and a second side portion. A total area of top light transmissive patterns within a top region divided by an area of the top region is T. The first and second side portions are respectively connected to the top portion, and each has multiple side light transmissive patterns. A total area of multiple side light transmissive patterns within a side region divided by an area of the side region is S. The patterns satisfy: 0.3×(B/A) Подробнее
