LED lamps are not equal to the difference between LED light sources

With the popularity of LED lamps, LED lamps have occupied more than half of the existing lighting market, but most people have always believed that LED lamps and LED light sources are the same thing, the same. This is not the case. There are many differences between them. There are obvious differences, so they cannot be confused.

This article refers to the address: http://

1, LED light source

LED light source; a component provided by an LED lamp or LED module.

LED lamp: A light source with a lamp head that combines one or more LED modules. The LED module cannot be removed unless permanently damaged.

2, LED lamps

LED luminaire; luminaire designed to use LED light sources.

A luminaire is defined as an appliance that distributes, reveals, or transforms one or more lamps, and includes all 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 a power source."

"Light effect" and "performance"

LED light source efficacy refers to the ratio of the luminous flux emitted by the light source to the electrical power it consumes; LED luminaire performance refers to the ratio of the initial total luminous flux emitted by the luminaire to the power consumed by the luminaire under the claimed conditions of use.

"Light effect" is used to evaluate LED light source. "Efficacy" is used to evaluate LED lamps. LED light source efficacy and LED lamp efficiency both indicate the efficiency of converting electrical energy into light energy, and are indicators for describing the energy-saving characteristics of lighting products.

Different luminous flux measurement methods

The luminous flux in the luminous efficacy of the LED light source is different from the measurement state of the luminous flux in the efficacy of the LED lamp. The luminous flux in the luminous effect of the LED light source is measured in the pulse state, and the light in the luminous effect is not directional, as long as the light can be emitted. , in either direction.

The luminous flux in the efficacy of an LED luminaire is measured at steady state, and the light in the performance is directional, and the light needs to be sent to an effective part.

Different enclosure protection levels

As a light source, there is no special enclosure protection rating or IP20. However, the enclosure protection level for indoor luminaires should be at least IP20, and the enclosure protection rating of LED road luminaires should be at least IPX3.

Therefore, we can see that LED lamps and LED light sources are two different concepts, you should not be confused with professional.
