What is The Brightest LED Strip on the market?
At present, the brightest LED strips on the market can achieve 5000lm/m. It adopts the design of 8LEDs/group, the light effect can reach 160-180lm/W, and the power can reach 30W/m. Of course, such a high power requires aluminum to cooperate with heat dissipation, otherwise, its light decay will be very high.To get more news about led neon rope light, you can visit htj-led.com official website.
Now there is also a design of 9 LEDs/group, and the luminous efficacy can reach 210lm/W, but this design has exceeded the limit, the power is relatively low, and the overall brightness is not high. Therefore, high-efficiency LED light strips do not mean the brightest LED light strips.This article will tell you all the factors that affect the brightness of LED strips through a more detailed introduction. By reading, you will know how to make the brightest LED light strip.
Luminous flux refers to the radiant power that the human eye can perceive, which is equal to the product of the radiant energy of a certain band per unit of time and the relative visibility of the band. Since the relative viewing rate of the human eye to different wavelengths of light is different, when the radiant power of different wavelengths of light is equal, the luminous flux is not equal.
The brightness of all LED strips is expressed by luminous flux. Due to the voltage drop problem of LED strips, the brightness parameters tested by different lengths are not the same. In order to be able to unify the standard, the brightness of the LED light strip refers to the result obtained by sticking the 1-meter LED light strip on the aluminum material and then testing it. The luminous flux of the LED light strip can be obtained through the test of the integrating sphere and the light distribution meter.
2.1 Brightness of LED strip = Luminous effect of LED strip * PowerThrough the above formula, we know that the two main factors that affect the brightness of the LED are the light effect of the LED strip and the power of the LED strip. So, if we want to make a brighter LED strip, we need to increase the light efficiency of the LED strip and the power of the LED strip at the same time.
2.2 Influencing factors of LED light efficiency
There are many factors that affect the light efficiency of LED strips, mainly the arrangement of LED lamp beads, different LED lamp beads, color rendering index, color temperature and current, etc.
2.2.1 90% high-efficiency LED light strip adopts the design of 7 LEDs/group or 8 LEDs/group
The arrangement of LED lamp beads is the main reason for the different light efficiency of different led light strips. Currently, 24V LED strips are designed with 5, 6, 7, 8, and 9 LEDs per group. We can use the table below to understand the difference in brightness between different arrangements.
In addition, not all LED strips can be designed with 8 LEDs/group or 9 LEDs/group. Generally speaking, in order to make the design quality of 8 LEDs/group led strips more stable, the Vf of the LED lamp beads needs to be lower than 2.87V when the light strip is working. For the design of 9 LEDs/group, Vf needs to be around 2.6V. Because it is relatively difficult to keep the Vf value at 2.6V, the power of the LED strip designed with 9 LEDs/group is relatively low.
2.2.2 90% high-efficiency LED strips use 2835 LED
2835 LED lamp bead is the most widely accepted led chip. With huge market sales, its cost is much lower under the same parameters. Moreover, compared with 5050, 3014, 3528, and other LED lamp beads, 2835 can not only achieve 0.5W/PCS but also have higher luminous efficiency. Therefore, more than 90% of the high-efficiency LED strips in the market are designed with 2835 lamp beads.
