Description
The present invention concerns a water based composition comprising at least light diffusion particles and a polyurethane resin, notably between 10 and 40 ％by weight of light diffusion particles and between 5 and 30 ％by weight of a polyurethane resin. The invention also concerns a method for coating at least a part of a surface, preferably the surface of a transparent substrate, comprising at least the step of a) applying the composition of the invention on at least a part of the surface and b) carrying out the coating forming on the surface. The present invention also concerns a LED assembly comprising at least a LED light source component and a transparent substrate having at least a part of the surface coated by a composition comprising at least light diffusion particles and a polyurethane resin.
The following discussion of the prior art is provided to place the invention in an appropriate technical context and enable the advantages of it to be more fully understood. It should be appreciated, however, that any discussion of the prior art throughout the specification should not be considered as an express or implied admission that such prior art is widely known or forms part of common general knowledge in the field.
Light emitting diode (LED) systems are becoming more prevalent as replacements for older lighting systems. LED systems have indeed the
advantages over traditional lighting solutions such as incandescent and fluorescent lighting as they use less energy, are more durable, operate longer, can be combined in multi-color arrays that can be controlled to deliver virtually any color light, and generally contain no lead or mercury.
In recent years, LED devices have been deployed in various applications, including indicators, light sensors, traffic lights, broadband data transmission, and illumination devices. For example, LED devices are often used in illumination devices provided to replace conventional incandescent light bulbs, such as those used in a troffer light.
However, LED devices typically are highly directional by nature. Common LED devices are flat and emit light from only one side. They produce intense light within the beam of their output, but dim light outside of that beam. Using multiple LEDs does not fully alleviate this problem, as there are then interference patterns in the light. Thus, although superior in performance, many commercially-available LED lamps cannot achieve intensity distribution of incandescent lamps.
It is then known to provide a light-transparent or light-filtering coating on a transparent substrate close to the LEDs, usually added to their shells or bodies, in order to improve the luminous intensity distribution by spreading out the light from the LED. However the known coating compositions do not permit to allow a scratch resistant homogeneous coating without letting appear bubble on the surface coating. Another method has been to roughen the surface of the LED package. Neither of these methods accomplishes uniform light distribution for an LED light
source, and may lower luminous efficiency. Methods of accomplishing approximate angular uniformity may also involve partially absorptive processes, further lowering luminous efficacy.
Therefore, while conventional LEDs have been generally adequate for their intended purposes, they have not been entirely satisfactory in every aspect. It is hence desired to provide LED assemblies that distribute light in more uniform fashion across all directions, similar to that of an incandescent light bulb.
INVENTION

The present invention also concerns a LED assembly comprising at least a LED light source component and a transparent substrate having at least a part of the surface coated by the above identified method. The invention also relates to a LED assembly comprising at least a LED light source component and a transparent substrate having at least a part of the surface coated by a composition comprising at least light diffusion particles, and a polyurethane resin.
Other characteristics, details and advantages of the invention will emerge even more fully upon reading the description which follows.

Polyurethane resin is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic
polyurethanes are also available. Polyurethane polymers are traditionally and most commonly formed by reacting a di-or polyisocyanate with a polyol containing on average two or more hydroxy groups per molecule, in the presence of a catalyst. Both the isocyanates and polyols used to make polyurethanes contain on average two or more functional groups per molecule.

Composition of the present invention may also comprise one or more additives, such as for instance an additive chosen in the group consisting of: polyether polyol, binders, dispersants, anti-scratch additives, and thickening agents.
Polyether polyols usually refer to polyols comprising poly (alkylene oxide) chains, which polyols are normally obtained by reacting a polyhydroxy initiator compound with at least one alkylene oxide and optionally other compounds.
Methods for preparing polyether polyols, also sometimes referred to as poly (oxyalkylene) polyols, are well known in the art. Typically, such methods involve reacting a starting compound having a plurality of active hydrogen atoms with one or more alkylene oxides, such as ethylene oxide, propylene oxide, butylene oxide or mixtures of two or more of these. Suitable starting compounds include polyfunctional alcohols, generally
containing 2 to 6 hydroxyl groups. Examples of such alcohols are glycol, such as diethylene glycol, dipropylene glycol, glycerol, di-and polyglycerols, pentaerythritol, trimethylolpropane, triethanolamine, sorbitol, sucrose, mannitol, etc. Usually a strong base like an alkali metal hydroxide (typically potassium hydroxide, cesium hydroxide or sodium hydroxide) is used as a catalyst in this type of reaction.
Polyether Polyol may be defined as a compound formed through the polymerization of ethylene oxide (EO) or propylene oxide (PO) or other cyclic ethers with compounds having one or more reactive hydrogens (i.e., a hydrogen atom bonded to nitrogen, oxygen, phosphorus, sulfur, etc. ) to form polyethers.

Composition of the invention may notably be applied on one or two faces of the surface.
The composition can be applied in a liquid state on a surface by dipping, spraying, roller coating, flooding, ink jet, pad printing, flexographic printing, and screen printing.
Coating forming is the generic term for the transition of a coating layer from the liquid state to the solid state, or hardening. The composition of the invention may be hardened in particular by a thermal method, usually by drying or UV hardening. The term "drying" is related to the process engineering used for drying the liquid layer, notably at a temperature comprised between 40 and 90℃, preferably between 50 and 80℃. Drying may notably occur under a hot air gas. The residual content of water in the coating is usually comprised between 20 and 70 ％by weight of the weight of the overall water.
The coating may notably be a layer of a thickness comprised between 5 and 30 μm, preferably comprised between 10 and 15μm.
