Description

A kind of LED light of adjustable brightness and colour temperature

Technical field

The utility model relates to LED lamp field more particularly to a kind of LED light of adjustable brightness and colour temperature.

Background technique

LED (Light Emitting Diode), light emitting diode are that one kind can convert electrical energy into consolidating for visible light The semiconductor devices of state, it can directly be converted electricity to light.The heart of LED is the chip of a semiconductor, one end of chip It is attached on a bracket, one end is cathode, and the other end connects the anode of power supply, is encapsulated entire chip by epoxy resin. Initial LED is used as the instruction light source of instrument and meter, and later various photochromic LED are obtained in traffic lights and large-area displays screen Extensive use has been arrived, good economic benefit and social benefit are produced.By taking 12 inches of red traffic light as an example, in beauty State was using the long-life originally, and for 140 watts of incandescent lamps of low luminous efficacy as light source, it generates the white light of 2000 lumens.Through red After colo(u)r filter, the feux rouges of 200 lumens is only left in light loss 90%.And in newly-designed lamp, Lumileds company uses 18 red LED light sources, including circuit loss, 14 watts of power consumption altogether can produce same light efficiency.Automobile signal light is also The key areas of LED light source application.LED light is one piece of electroluminescent chip of semiconductor material, is arrived with elargol or latex solidified On bracket, is then sealed with silver wire or gold thread connection chip and circuit board, surrounding with epoxy resin, play protection internal core Effect, finally installs shell, so the anti-seismic performance of LED light is good.

Colour temperature is the measurement unit indicated in light comprising color component.Theoretically, colour temperature refers to absolutely black The color that body is presented after heating since absolute zero (one 273 DEG C).Black matrix after heated is gradually red by blacking, turns Huang, hair It is white, finally issue blue light.This temperature is known as when being heated to spectral component contained by the light that certain temperature black matrix issues The lower colour temperature of degree, measurement unit be " K " (Kelvin) if, the light that issues of a certain light source, with black matrix sending at a certain temperature The identical of spectral component contained by light is the color for being known as certain K colour temperature, such as 100W light bulb sending light, with absolute black body in 2527K Color it is identical, then the colour temperature of light that this light bulb issues is exactly: 2527K+273K=2800K.

Brightness refers to the physical quantity of (reflective) power of illuminator (refractive body) surface light emitting.Human eye light from a direction Singly source, the light source area ratio of light intensity and human eye institute " seeing " in this direction, is defined as the brightness of the light source unit, i.e., Luminous intensity in the projected area of position.The unit of brightness is that candela/square metre brightness is impression of the people to the intensity of light.It is One subjective amount.It is different from illuminance, it is light intensity by the objective corresponding amount of physical definition.The two amounts are general It is often confused in works and expressions for everyday use.Brightness is also referred to as lightness, indicates the bright-dark degree of color.The brightness that human eye is experienced is color What the light of reflection or transmission was determined.

Existing LED light cannot be carried out while be adjusted to brightness and colour temperature, affected the application range of LED light, therefore, needed Design the LED light of a kind of adjustable brightness and colour temperature.
