With the popularity of these LED lighting lamps and lanterns, LED lamps and lanterns already permeate every aspect of life, holds the most existing lighting market, but many people have been mistaken, LED lamps and the LED light source is the same concept, but in fact is not the case, has obvious difference between them, not even comparable, cannot confuse STH with STH else.
1, LED light source in terms of structure, the LED light source,
LED光源)
Is the
commercial ceiling lamps or LED module provides components.
LED lights,
LED灯)
: with a lamp holder, the combination of one or more of the LED module light source, unless the permanent damage, LED module cannot be removed.
Lamps and lanterns is defined to allocate, filters or transforms one or more of the lamp light of an apparatus, and including supporting, fixed and protect the light all the necessary components (
But not including the lamp itself)
Assist device, as well as the necessary circuit and connect them with the power supply device.
In addition, from the light efficiency and performance, luminous flux measurement method, etc. , can all make a clear distinction between the two.
Photosynthetic efficiency and effectiveness of luminous flux LED light photosynthetic efficiency refers to the source and the ratio of the electrical power consumed;
And LED lamps and lanterns of effectiveness refers to the lamps and lanterns of claims under the conditions of use, lamps and lanterns from the initial total luminous flux and the ratio of the power consumption.
Is helpful to evaluate the LED light source, the efficiency to evaluate LED lamps and lanterns, LED lights and LED lighting lamps and lanterns effectiveness is used for the efficiency of electric energy into light energy, is to describe lighting products index of energy-saving features.
Different luminous flux of LED light source lighting luminous flux measurement method, and the LED lamps and lanterns effectiveness of luminous flux measurement condition is different, the LED light source light efficiency of luminous flux is measured in pulse state, photosynthetic efficiency of light is no directivity, as long as the light out, whether can be any one direction.
And efficiency of luminous flux LED lamps and lanterns, is measured under steady state, efficiency of light is somewhat directivity, need to effective parts to light.
Different protection grade as a light source, no special requirements or should achieve IP20 protection grade.
But, for indoor lamps and lanterns should reach at least IP20 protection grade, LED road lamps and lanterns should reach at least IPX3 protection grade.
What has been discussed above, we can see the LED lamps and lanterns and LED light source are two different concepts, from the power of the structure performance, are each have differences, don't confuse.
