5050 3528 patch which is better

5050 per luminous flux 15-22lm 3538 is also 4-5lm, 5050 volume is larger The heat dissipation requirements are basically the same, depending on what you are using, consider the volume and luminous flux OK It doesn't matter which one is better, 5050** is a little higher. I hope you are not looking for a good manufacturer, brother is to do LED, I hope there are not too many water army advertisements.

If we do not consider the material and external power supply and other factors, it is considered to be the same, and the main cause of light decay is the high-temperature decay of junction temperature and phosphor. All things considered, the light decay of 5050 is smaller than that of 3528.

The area of 5050 has 3 lamp beads, each lamp bead accounts for 2500 3 about 830mil 2, and the area of 3028 is 840mil 2, but the height is sum, the main cause of light decay is temperature, under the same lamp bead current, the heat generated is the same, the difference is in the heat dissipation capacity, because the thickness of 5050 is small - the thermal resistance is small - the junction temperature is low, so the light decay of 5050 is small.

The light decay produced by the same phosphor at low temperatures is also increased to an important point, which further reduces the light decay.

The power of the LED3528 patch is; The power of the 5050 patch is:

The larger the current of the 5050 patch, the higher the voltage, the higher the temperature, the smaller the current, the luminous angle: 125 degrees, etc., the forward current is 60mA, the reverse voltage is the most slippery, and the working temperature is best between -35 +60. If the light decay life is not considered, it can also operate below +85 degrees.

The light intensity of the 5050 patch can reach 5500-6000mcd (pure white light, slightly smaller for warm light), and the working voltage is the same as that of ordinary LEDs, only the current is the same, which is 60mA.

The power of the LED3528 patch is; The power of the 5050 patch is:

The larger the current of the 5050 patch, the higher the voltage, the higher the temperature, the smaller the current, the luminous angle: 125 degrees, etc., the forward current is 60mA, the maximum reverse voltage cannot exceed 5V, and the working temperature is best between -35 +60. If the light decay life is not considered, it can also operate below +85 degrees.

The light intensity of the 5050 patch can reach 5500-6000mcd (pure white light, slightly smaller warm light), and the working voltage is the same as that of ordinary LEDs, only need, and the current is the same, which is 60mA.

5050 power at 43-46 mA, 46-53 mA, 54-60 mA;

3528 power is generally.

3528 is generally, 5050 is complicated, it may be.

3528 and 5050 are divided into watts, 3528 is a small power watt, 5050 is a watt, but 5050 can also be made into a watt or 1w package.

Our company's packaging of 3528 is, 5050 is, the power can be packaged according to the requirements of their own products, if you want to know more about it, you can also hit the following ** I consult.

The 5050 LED SMD LED package is a package of three LEDs together with six pins. and 3528 SMD LED packages with single, two pins.

The package size of 5050LED is 5mm*5mm*, and the light intensity can reach 5500-6000mcd (pure white light, slightly smaller warm light). His working voltage is the same as that of ordinary LEDs, only 60mA is required.

Because the size of the 5050 SMD LED is relatively small and the workmanship is relatively fine, it is not very convenient to weld manually, but it does not mean that it cannot be welded, and the welding temperature should be controlled within 250 degrees, otherwise it will burn the more expensive 5050 SMD LED.

Because the parameters of 5050 SMD LED determine that he must be a favorite LED, so he is often used in high-end civil energy-saving lamps, car dashboards, LED strips, mobile phone backlights and buttons, instrument backlights and products that require small volume LEDs, LED backlights, switches and signs, caller ID, flash, cars, audio, indoor displays, lighting fixtures market!

1. Current: 43-46mA (this is the most ideal driving current); The maximum current used should not exceed 60mA;

2. The voltage requires that the instantaneous voltage of the lamp bead cannot exceed 5V, or the LED lamp bead will be damaged or seriously damaged and cannot be repaired);

3. Ambient temperature -20 +40 (the heat dissipation design of the lamp is required to be better, and the temperature of the LED lamp pin cannot exceed 60 degrees);

4. If the current is 14-20mA, for every 1mA current decreased, its brightness will be reduced by 4%;

5. The current is 43-46ma, 46-53ma, and 54-60mA;

6. Low power consumption.

7. Long service life.

With the right current and voltage, LEDs can last up to 100,000 hours.

8. High brightness and low heat.

Less thermal radiation than HID or incandescent lamps.

9. Environmental protection. LEDs are made of non-toxic materials, unlike fluorescent lamps that contain mercury that can cause pollution, and LEDs can also be reused.

10. Sturdy and durable.

LEDs are completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There are no loose parts in the lamp body, which makes the LED not easy to damage.

11. Strong controllability.

It is easy to change colors and brightness and light, and it is very responsive.
