Description
Technical field
The utility model relates to a kind of lighting device with distinguishing colours, especially accurately can identify the colour discrimination lamp tool of fabric color, is specially a kind of LED colour discrimination lamp.
Background technology
At present, the LED lamp of prior art is combined by driving power, white light LEDs, wiring board, heat-dissipating casing and diffuser.Driving power supplies energy to white light LEDs the direct current that the High Level AC Voltage of input changes into low pressure; White light LEDs becomes the luminous energy of heat energy and visible ray electric energy conversion; Heat-dissipating casing leads away the heat energy concentrated, and improves the output of white light LEDs luminous energy.Diffuser changes into area source the spot light of LED, makes human eye perceives light softer comfortable.After the visible light-transmissive diffuser that white light LEDs sends, be irradiated on object, object absorbs a part of light, antireflection part light, and human eye can distinguish the color of this object, and what lean on is exactly the reverberation entering eyes.
But, containing fluorescent material in the composition material of a lot of object, particularly some garment panel, the optical wavelength of former incident light can be changed.Such cloth is irradiated by the LED lamp in currently available technology, seem that color is very close, but take sunshine or watch color relation in case of checking colors and have difference clearly, this is to clothing factory, and printing house etc. require that to color distinguishing of the color of high occasion is made troubles.The luminescent spectrum of existing LED lamp is plentiful not, can not accurately differentiate object true colors.
Utility model content
In order to solve the problem, the utility model carries a kind of LED colour discrimination lamp, overcome light fixture of the prior art and distinguish that look performance is low to the material containing fluorescent material, the requirement of high standard color discrimination, luminescent spectrum is plentiful not, accurately can not differentiate the defect of object true colors.
The utility model adopts following technical scheme:
A kind of LED colour discrimination lamp, comprise diffuser, purple light LED, white light LEDs, aluminum-based circuit board, radiation aluminium, driving power and lamp deck, described diffuser is arranged on radiation aluminium, diffuser can be buckled on radiation aluminium, base circuit board is arranged in radiation aluminium, base circuit board is arranged purple light LED and white light LEDs, driving power is arranged in the cavity of radiation aluminium, and lamp deck is buckled on radiation aluminium.The quantity of described white light LEDs and purple light LED presses 2:1 Homogeneous phase mixing arrangement in aluminum-based circuit board, and the annexation between white light LEDs with purple light LED, for connecting, carries out parallel connection or series-parallel connection between lamp group again.For preventing purple light from directly entering eyes, diffuser is nontransparent atomization diffusion shell, and make white light and purple light in lamp interior just fully mixing, the light transmitted is pure and spectrum abundant, and described diffuser is fluorescent tube shape diffuser or bulb-shaped diffuser.Described lamp deck is fluorescent tube deck or bulb deck.Described LED colour discrimination lamp is LED colour discrimination lamp pipe or LED colour discrimination lamp bubble.
The utility model, on the wiring board of arrangement white light LEDs, increases by one group of purple light LED.When energized, white light LEDs and purple light LED are simultaneously luminous, and the light be radiated at like this on object also add purple light composition except the light of common LED, and the chromatic discrimination power of this LED lamp is strengthened greatly.According to luminosity curve function and the measuring of human eye, the optical parametric of described purple light LED is: peak wavelength=380nm to 420nm, dominant wavelength=440nm to 460nm, half-wave is wide=10nm to 15nm, luminous flux ratio=0.005 to 0.008 of purple light LED and white light LEDs, luminous power ratio=0.16 to 0.26 of purple light LED and white light LEDs.As shown in Figure 3, the representative white light LEDs of the representative purple light LED of DS beginning, D beginning, the annexation between white light LEDs with purple light LED, for connecting, carries out parallel connection or series-parallel connection between lamp group again.Due to light flux ratio white light LEDs much lower of purple light LED, thus arrange on pcb board LED position time require it is that purple light LED and white light LEDs are evenly arranged separately.
Measure by experiment: the spectrum of white light LEDs is too low at the composition of purple light position compared with natural daylight, causes chromatic discrimination power to weaken.On Conventional white LED basis, add purple light LED, because the wavelength of white light LEDs and purple light LED is different, the forward voltage of energising is different, so white light LEDs and purple light LED are series relationship, in order to the natural effect of the uniform light reaching out, the arrangement position of white light LEDs and purple light LED is even separately, and light from diffuser out before fully mix.
In addition, the fluorescent material of purple light also can be participated in Conventional white LED; Same LED is packaged with the wafer of purple light.
The beneficial effects of the utility model are: (1), on the basis of white light LED lamp, additionally adds purple light LED, supplement the shortcoming that original light fixture spectrum does not enrich, and improve chromatic discrimination power; (2) have energy-efficient, the feature that environmental protection and life-span are long; (3) photochromic stable, be easy to store transport, without mercury, without stroboscopic.
