Introduction:

The powder is a kind of yellow phosphor for LED encapsulation use with the characteristics of high brightness,good stability and no harm to human and environment, which is fired through special manufacturing techniques. This kind of powder is quite applicable to the encapsulation of high color rendering white LED or other lighting appliances.

Product’s main performance and advantages:

Appearance: Yellow crystalline powder

Chemical composition: Rare earth aluminate

Physical stability: waterproof and heatproof. No any changes under -50°C to 300°C in the air.

Chemical stability: under 200°C, brightness >90%; within 1000 hours after encapsulation, brightness decay

Safety: Conform to the RoHS {EU (Restriction of Hazardous Substances)} and all security standards. Non-poisonous,

non- radioactivity and do no harm to human and environment.

Extensive usage: it applies to various LED encapsulation from cool white to warm white. The rendering index can be up to 98 with red powder.

Product index:

Encapsulation testing (540B, wavecrest 542.6nm)

Brightness testing result:

1.Testing result of integrated high-power luminophor:

2.Testing result of low-power single prismatic pearl (60mW):

3.Testing result of 1000 hours’ aging:

4.Using instruction:

Separate the powder in the epoxy glue or silica gel uniformly, after deaeration, dot the powder on the CMOS chip, the LED encapsulation will be finished after solidification, etc. It also can be used after mixing with other phosphor (such as red and green powder) in certain proportion to get your required color temperature or rendering index.

5.Package and preservation:

Package:50g/bottle,100g/bottle,200g/bottle.

Preservation condition:keep the powder in a closed container and deposit in a clean dry place when not in use.
