What does Triphosphor mean?

What does Triphosphor mean?

Definition of triphosphate : a salt or acid that contains three phosphate groups — compare atp, gtp.

What phosphor is in a fluorescent light?

In a fluorescent lamp, the emitted light is generated by a phosphor layer which is deposited on the inner side of a glass tube. The phosphor is excited by ultraviolet light, which is typically generated with a gas discharge in low-pressure mercury vapor….

What is Halo phosphor?

A wide variety of different whites can be created by the halophosphate system. The phosphor is in fact a blend of two different materials which radiate broadly in the blue and orange parts of the spectrum respectively. By changing the ratio of the two components a full range of warm to cool white hues can be achieved.

What does 840 mean on a fluorescent tube?

The first digit is the CRI with 8 representing 80% and 6 representing 60% etc. The last 2 digits are the colour temperature in hundreds of Kelvin so 6000K would be represented by 60. So for example 840 means the lamp has a CRI of 80% and a colour temperature of 4000K.

What is the white powder inside a fluorescent tube?

The white powder that you see inside a fluorescent light bulb is called phosphor, which is a substance that emits visible light whenever it absorbs ultra violet energy waves. The phosphor used in a fluorescent light bulb is what determines both the color temperature and the color rendering index.

Which of the following has best lamp efficiency?

Detailed Solution. A graphene LED light bulb is simply an LED light bulb where the filament has been coated in graphene. A graphene LED bulb is reported to be 10% more efficient than regular LED light bulbs.

Is phosphor and phosphorus same?

Phosphorus, the light-emitting chemical element for which phosphors are named, emits light due to chemiluminescence, not phosphorescence.

Why phosphorus is used in CRT?

The electron beam is directed towards the front of the CRT screen. A coating of Phosphor material is made on the inner surface of the screen. The phosphor emits light when it is struck by electron beam. The color of the emitted light depends on the phosphor substance used.

What does G13 mean on fluorescent tube?

Fluorescent G13 tube base types are a two pin fitting located at each of the tube with 13mm between the two pins. The T8 (26mm diameter) and T12 (38mm diameter) uses the G13 cap fitting. G13 tube fittings are commonly used in kitchens, garages, and office buildings.
