Abstract: With the popularity of LED lamps, LED lamps have occupied most of the existing lighting market, but most people have always believed that LED lamps and LED light source is one thing, is the same. Is not the case, there are many differences between them, there is a clear distinction, therefore, can not be confused.
With the popularity of LED lamps, LED lamps have occupied the majority of the existing lighting market, but most people have always believed that LED lamps and LED light source is one thing, is the same. Is not the case, there are many differences between them, there is a clear distinction, therefore, can not be confused.
1, LED light source
LED light source (LED light source); LED lights or LED module to provide the components.
LED lamp (LED lamp): with a lamp, a combination of one or more LED module light source, unless permanently damaged, LED module can not be removed. The following are the same as the "
2, LED lighting
LED lamps (LED luminaire); designed to use LED light source lamps.
Luminaire is defined as a device that distributes, exposes, or transitions one or more lights to light and includes all the components necessary to support, secure, and protect the lamp (but not the lamp itself), and the necessary circuitry Auxiliary devices and devices that connect them to the power supply.
"Light effect" and "performance"
LED light source efficiency refers to the luminous flux emitted by the light source and the ratio of the electric power consumed by it. The efficiency of the LED lamp is the ratio of the total luminous flux emitted by the lamp to the power consumed by the lamp under the claimed condition of the lamp.
"Light effect" for the evaluation of LED light source, "performance" for the evaluation of LED lamps, LED light source efficiency and LED lamp performance that energy conversion into light energy efficiency, is to describe the lighting products, energy-saving characteristics of the indicators.
The luminous flux measurement method is different
LED light source luminous flux and LED lamp performance in the luminous flux measurement of the state is different, LED light source luminous flux in the pulse state is measured, the light efficiency of the light is nothing, as long as the light can be issued , Either in any direction can be.
LED luminous flux in the performance of the luminous flux is measured in the steady state, the performance of the light is directed, the light needs to be sent to the effective parts can.
The enclosure has a different degree of protection
As a light source, there is no special enclosure protection rating requirement or should reach IP20. However, for indoor lighting enclosure protection level should be at least IP20, LED road lighting enclosure protection level should reach at least IPX3.
Therefore, we can see LED lamps and LED light source is two different concepts, professional you do not confuse.
