With the emergence of the LED lamps and lanterns, use the lamps and lanterns of LED module most take the form of non-replaceable, seems to present a trend of integration of, LED light source and the boundaries of LED lamps and lanterns also seems to be not clear.
Actually in quite a lot of consumer's eyes, the LED light source and LED tube light, lamps and lanterns is similar, but both in professional lighting people's eyes is not the same.
Today, in many aspects to contrast and interpretation, the LED light source and LED tube light, etc. The difference of lamps and lanterns, take a look at.
。
。
The characteristics of the light source is used by different lamps and lanterns light source is used by the lamps and lanterns.
Light source compared to the source water, lamps and lanterns compared to spring.
The LED light source can be either in LED tube light, and can be used on the LED street lamps and lanterns.
LED light source is not the same as the LED lighting lamps and lanterns of effectiveness in terms of light source, light efficiency is a classic indicators project, each kind of new light source directly related to its reach higher photosynthetic efficiency, thus, photosynthetic efficiency without exception also become an important index of the performance of the LED light source.
Light source, of course, the other performance index of the project also includes color rendering index, color coordinate, color moderate life and so on.
To use the lamps and lanterns of traditional light source, LED lamps and lanterns, light output conversion light source of lamps and lanterns namely the ability of luminous flux, is a classic indicators of performance of lamps and lanterns.
Due to the LED light source has not yet reached the degree of standardization of performance parameters, and many kinds of lamps and lanterns of LED light source cannot be replaced, so also misused to the concept of the LED lighting lamps and lanterns.
LED light source and LED lighting lamps and lanterns of efficiency of the concept of LED light source photosynthetic efficiency is defined as a source of luminous flux and the ratio of the electric power consumed.
Units for lm/W.
It is not include loss of electrical accessories.
LED lamps and lanterns effectiveness definition refers to the lamps and lanterns of claims under the conditions of use, from the initial total luminous flux of lamps and lanterns and the ratio of the power consumption, unit for lm/W.
Is the loss of the contain electrical accessories.
To evaluate LED lighting 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, lighting product indicators project of energy saving features as described, but its connotation is different.
Efficiency of LED lamps and lanterns and LED light source lighting involved because of the relationship between luminous flux and the scope of the electrical power is different, cause the efficiency of LED light source is different from the LED lighting lamps and lanterns, light source, lamps and lanterns of photosynthetic efficiency than efficiency.
One is LED into the lamps and lanterns, junction temperature rise, high light output (
Heat loss)
；
Secondly, light source into the lamps and lanterns, and USES the LED control device or the power supply after the loss of system;
Third is the loss of the light after lamps and lanterns of optical system, the efficiency of lamps and lanterns,
Light loss)

Efficiency of lamps and lanterns = light photosynthetic efficiency & times;

LED lamps and the LED light source is the definition of the LED lamps and lanterns can 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.
And the LED light source is
commercial ceiling lamps or LED module provides components.
LED spotlights and lamps and lanterns is for the use of LED lighting lamps and lanterns.
LED lamp type of diagram can be seen from the above analysis, the light source light efficiency and effectiveness of lamps and lanterns is completely different, cannot confuse STH with STH else.
In this paper, by the LED spotlights manufacturer, from the above can learn in a few more professional analysis, LED lamps and the LED light source in all aspects have different difference.
