6 Commonly Used Parameters of Led Flashlights


We can judge the pros and cons of LED flashlights by understanding the commonly used parameters of LED flashlights. This article will specifically introduce the six commonly used parameters of LED flashlights.

an introduction to the six common parameters of LED flashlights

The LED flashlight is a new type of lighting tool with light-emitting diodes as the light source. It has the advantages of power saving, durability, and strong brightness. However, under different scenarios and uses, the required LED brightest led flashlight specific parameter values are also different. The following is an introduction to the six common parameters of LED flashlights.

1. Luminous flux (Ф)

Unit: Lumen (lm)

The total amount of energy emitted by the light source and received by human eyes is the luminous flux (Ф)
2. Light intensity(I)

Unit: Candela (cd)

Generally speaking, light rays are emitted in different directions and have different intensities. The intensity of visible light emitted in a specific direction is called light intensity (I)

3. Illuminance (E)

Unit: Lux (lx)

Illuminance (E) is the proportional coefficient between the luminous flux and the illuminated area. According to the classification of rechargeable flashlights, flashlights are mainly divided into two types: rechargeable battery flashlights and non-rechargeable battery flashlights. Rechargeable flashlights are further divided into lead-acid batteries, lithium batteries, NI-H batteries, etc. through the classification of batteries. As lead-acid batteries are currently cheap, they have a relatively large share in the market.

1lx refers to the brightness of 1lm luminous flux evenly distributed on a plane of 1lm2.

4. Brightness

Unit: Candela/square meter [cd/m2]

Brightness refers to the intensity of the reflected light from an object seen by the eye from a certain direction.

5. Light effect

Unit: Lumen [lm/w]

Light efficiency refers to the efficiency at which electrical energy is converted into light. LED flashlight is a new type of flashlight with LED (light-emitting diode) as the light source. Because LED has the characteristics of high brightness, low power consumption, long life, small size, etc., it is an ideal choice for portable lighting.

6. Color temperature

Unit: Kelvin (k)

When the color emitted by the light source is the same as the color radiated by the "black body" at a certain temperature, the temperature of the "black body" becomes the color temperature of the light source. The higher the temperature of the "black body", the more blue components in the spectrum, and the fewer red components. For example, the light color of an incandescent lamp is warm white, and its color temperature is expressed as 2700K, while the color temperature of a daylight fluorescent lamp is expressed as 6000K.
