As far as I know, nothing. It is the color bands on the resistor that represent the value of the resistor.AnswerIn the, now-obsolete, 'body-tip-spot' colour code system, the 'body' colour represented the first significant figure, the 'tip' colour represented the second significant figure, and the 'spot' colour represented the multiplier. The colours of the 'body-tip-spot' method correspend exactly to the colours used with the 'band' method.With the 'body-tip-spot' method, the body of the resistor was painted in one colour; one end of the resistor (the 'tip') was painted another colour, and a coloured 'spot' or 'dot', was placed roughly halfway along the body of the resistor.
When you want test LED street, you should know what's parameters you want test. And there have many things need to test, but mian for light luminous flux, color temperature, color redening index, light distribution intensity cruve, IES files. And there have two equipments to test these parameters, one is Spectroradiometer and integrating sphere system, like Lisun LPCE-2(LMS-9000A) Spectroradiomeetr and Integrating Sphere Test System, this one is for lumen, CCT, CRI etc test; another is Goniophotometer System.
Hexadecimal color values are representative of variations in Red, Green and Blue (RGB) color, within the structure of the Hexadecimal, or Base 16 positional numeral system. Within this system, values are represented 0-9, and A-F (representing 11-16). The structure of hexadecimal color value is actually three sets of two digit hexadecimal numbers (e.g. 0F 28 7D). The first value set determines the amount of red, the second green, and the third blue. Within each set, the first number is in value increments of 16, and the second in increments of 1. Where "12 34 56" represents 18 levels of red, 52 levels of green, and 36 levels of blue. You can get a pretty good feel for this color system by playing with the tool over at ColourLovers (see related link.)
The hexadecimal system
it is represented by color coded wires
The color of the wiring in the electrical system can vary, but common colors include blue, brown, green, and yellow.
The ground wire in a house electrical system is typically green or bare copper.
The different color options available for wires in an electrical system include black, white, and green.
In a typical household wiring system, the standard color coding for electrical wires is white for neutral wires and black for hot wires.
The European electrical color code is a standard system used to identify different wires in electrical wiring systems. In this system, the colors of wires indicate their function or purpose, such as live, neutral, and ground. This helps electricians and technicians easily identify and connect the wires correctly, ensuring safe and efficient electrical installations.
The symbol for a high pressure system is typically represented in blue on weather maps.
Leadership is represented by the color brown.
The House of Commons is represented by the color Green while the House of Lords in represented by the color Red.
u die
The main electrical ground wire is sized to the service and is non insulted bare copper. Branch circuit grounds are green in conduit installations and bare copper again in house wiring cables.
As invisible: People of color were not represented as often as whites.
