3528\5050 LED patch analysis and its testing technology basic knowledge points

5050 LED chip led package and 3528 patch led package detailed

1, 3528 What is the difference between patch led and 5050 patch?

Mainly representative of the size of the specification: 35mm * 28mm, 50mm * 50mm size is not the same, the power is not the same, in the application of the patch, 3528 no matter the brightness or the life is not 5050 has an advantage, the size is not same.

2. What is the use of the 3528 and 5050 SMD LEDs?

3528, 5050, are the finished lamp sizes in the form of SMD surface-mount LED packages . Name by size.

The surface-mounted SMD lamp has a lower brightness than the in-line DIP lamp, but the maintenance is convenient and the viewing angle is larger. Therefore, almost all SMD SMD LEDs are used in indoor LED displays .

3, LED flexible strip 5050

The 5050 is the model number of the LED package. Named after the size specification. Refers to the 5050 model LED lamp bead.

4. What is the use of the 3,528 and 5050 SMD LEDs?

3528, 5050, are the finished lamp sizes in the form of SMD surface-mount LED packages. Name by size.

The surface-mounted SMD lamp has a lower brightness than the in-line DIP lamp, but the maintenance is convenient and the viewing angle is larger. Therefore, almost all SMD SMD LEDs are used in indoor LED displays.

5, compatible with piranha 02.03.04 how? SMD is how? High power is how piranha is composed of SMD chips, 02.03.04 is the model of the LED bracket.

Abbreviation for Surface Mounted Devices, meaning: Surface Mount Device SMD is a unified model of the product. For example: TOP, Chip, can be SMD, which is a flat package.

The SMD chip is a bit general and uses a 5050 or 3528 chip to make a piranha.

Of course, there are many different chip sizes. Often used to make SMD sizes ranging from 7 x 9 mil to -24 x 10 mil.

The high power is: if the voltage exceeds 0.5W, it can be called high power.

Basic knowledge of LED test technology

[Forward voltage] The voltage drop generated between the two poles when the forward current of the LED is a certain value.

[Reverse Current] The current flowing through the LED when the reverse voltage across the LED is a certain value.

[Peak Wavelength] The wavelength at which the spectral radiation power is the largest.

[Half-intensity angle] In the illuminating (or radiant) intensity distribution, the illuminating (or radiant) illuminating intensity is greater than or equal to the angle formed by half of the maximum intensity.

[Primary wavelength] Any color can be seen as a certain spectral color mixed with a reference light source (such as CIE standard light source A, B, C, etc., energy source E, standard illuminant D65, etc.) The color that comes out, this spectral color is the dominant wavelength of the color. The dominant wavelength of the color is equivalent to the hue (mental amount) of the color observed by the human eye. If the chromaticity coordinates of the LED device under test have been obtained, an equivalent energy white light source (x0=0.3333, y0 = 0.3333) can be used as the reference source to calculate the dominant wavelength of the determined color. In the calculation, according to the slope of the straight line connecting the reference light source chromaticity point and the sample color chromaticity point on the chromaticity diagram, look up the intersection of the readout straight line and the spectral trajectory to determine the dominant wavelength.

[Average Strength] The ratio of the luminous flux dΦv contained in a small solid angle element of a light source in a given direction to this solid angle dΩ is Candela (cd)

[Radiation Bandwidth] The wavelength interval at which the spectral radiant power is greater than or equal to half the maximum value.

3D printing on the pen machine is mainly used in 3 d printing pen, is made from a special custom Dc Gear Motor, mainly used in 3 d printing pen, pen 3 d printing machine has been updated three generations according to the requirements of product.


3D Printing Motor product introduction:

The 3D Printing Motor is based on the deceleration Motor, coupled with supporting gears and ball bearings.The role of the gear reducer is to provide lower speed and greater torque.At the same time, gear box different deceleration ratio can provide different speed and torque.It's mostly rolling.

Operating temperature range:

3D Printing Motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at  ordinary room temperature catalog specifications re based on use at ordinary room temperature  (approximately20~25℃.

If a 3D Printing Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.


Storage temperature range:

3D Printing Motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.


Service life:

The longevity of 3D Printing Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
