LED lamp beads, those product models are more than the top of the mold

There are many models, take the products of Lepower as an example, there are many kinds, as for the model is the brightest, this kind of question is not right, different models are suitable for different scenes, and these models will also have different production technology and packaging technology, which will affect the use of lamp beads, Lepower shares are very strong in the research and development and production of lamp beads, you can take a look at their products.

LED lamp beads are divided into 4 types of LED lamp beads in the form of lamp beads, mainly in-line LED lamp beads, SMD LED lamp beads, high-power LED lamp beads and COB LED lamp beads.

At present, the LED market uses more in-line LED lamp beads and SMD LED lamp beads. The in-line LED lamp beads have low power, low heating, easy welding, complete specifications and models, and can be packaged into 15-20 degrees, 30 degrees, 45 degrees, 60 degrees, 90-120 degrees, and even some other high-brightness small lamp beads with a light gathering angle.

SMD LED lamp beads have a complete variety, which can be used as a high-speed placement machine, whether it is an indicator light or a general lighting product, they are found in many places.

Features of LED lamp beads

1. Voltage: LED lamp beads use low-voltage power supply, and the power supply voltage is between 2-4V, which varies according to different products, so it is driven by a safer power supply than high-voltage power supply, especially suitable for public places.

2. Current: The working current is 0-15mA, and the brightness becomes brighter with the increase of current.

3. Efficiency: The energy consumption is 80% less than that of incandescent lamps with the same light effect.

4. Applicability: Very small, each unit LED piece is 3-5mm square, so it can be prepared into various shapes of devices, and suitable for volatile environments.

Lamp beads are an important part of LED lights, what are the parameters of LED lamp beads? Today, PCHOUSE will answer them for you one by one.

1. Brightness. The brightness of LED lamp beads is different, ** different.

Lamp beads: the general brightness is 60-70lm; Bulb light: The general brightness is 80-90lm.

1W red light, the brightness is generally 30-40lm; 1W green light, the brightness is generally 60-80lm; 1W yellow light, the brightness is generally 30-50lm; 1W blue light, the brightness is generally 20-30lm.

Note: 1W brightness is 60-110LM; 3W brightness up to 240LM; 5W-300W is an integrated chip, with a series-parallel package, mainly depending on how much current, voltage, how many series and how many parallel.

LED lens: primary lenses are generally made of PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials. The larger the angle, the higher the light output efficiency, and with a small angle LED lens, the light should be shot far.

2. Wavelength. The wavelength is the same, the color is the same. then ** high.

White light is divided into warm colors (color temperature 2700-4000K), positive white (color temperature 5500-6000K), and cool white (color temperature above 7000K) Europeans prefer warm white.

Red light: band 600-680, of which 620, 630 is mainly used for stage lights, 690 is close to infrared.

Blue light: 430-480 band, of which 460, 465 stage lights are used more.

Green light: 500-580 band, of which 525, 530 stage lights are used more.

3. Luminous angle.

LEDs emit different light angles depending on their use. Special light angle, ** high.

4. Antistatic ability.

LED lamp beads with strong antistatic ability have a long service life, so they are high. Usually the antistatic is greater than 700V LED lamp beads can be used for LED lighting.

5. Leakage current.

LED lamp beads are unidirectional conductive luminaires, if there is a reverse current, it is called leakage, LED lamp beads with large leakage current, short life, ** low.

Summary. Hello dear. Expand on it for you.

The model of LED is divided into red, orange, green (subdivided into yellow-green, standard green and pure green), blue light, etc. In addition, some light-emitting diodes contain two or three colors of chips.

According to the light output of the light-emitting diode doped or not doped with scattering agent, colored or colorless, the light-emitting diode of the above various colors can also be divided into four types: colored transparent, colorless transparent colored scattering and colorless scattering. Scattering type light-emitting diode and up to do indication according to the characteristics of the luminous tube glossy surface: according to the light-emitting tube glossy surface characteristics are divided into round lamps, square lamps, rectangular, surface light-emitting tubes, lateral tubes, surface mounting microtubes, etc.

I don't know much about this aspect when I first came into contact with it, so how to fill in the part number if I give an LED light model.

Dear, you can fill in the model number on the LED light.

Just write two numbers?

Is h7 just filling in this?

Is ledh7 good?

Kiss. That's it.

The LED high-power market is now basically divided into two categories: ordinary high-power LEDs and integrated high-power LEDs. The ordinary high-power LED is divided into two types: monochromatic light and RGB full-color, and the integrated high-power LED is generally monochromatic, and there are very few RGB full-color.

There are three main series, the first is the most commonly used imitation lumens of high-power lamp beads, but this kind of lamp beads have one of the most inconvenient places that can only be pasted by hand, can not be placed on the placement machine, and can not pass through the reflow oven, so it can only be manually welded or on the heating table.

The second is Cree's SMD series, the lamp beads are smaller, and the SMD is very convenient, but because of its small size, it requires a small heat generation of the chip, so the requirements for the chip are very high, mainly because Cree is doing (or using Cree's chip), ** is also relatively high.

The third is Samsung's 5630 (5730), which is between high power and low power, which can only be used in general, which is more convenient for patches, but not convenient for using lenses, so the use of opaque cover lamps has a lot of use of it.

Another is the integrated lamp beads, which should be determined by the number and size of chips.

High-power LED lamp bead models, conventional ones with high power, as well as integrated lamp bead models, and some are divided into 1W-10W, which are relatively common.

According to the power, it can be divided into two kinds: 1, high-power lamp beads, 2, low-power lamp beads. According to the welding method, it can also be divided into two types:

1. Plug-in lamp beads, such as straw hat lamps, piranha lamp beads... 2. SMD lamp beads, such as low-power SMD 5050, 3014, 3528, 6030,。。 The main thing is to look at the size of the package by model.

There are also high-power 1W or 3W SMD high-power lamp beads.

There is also a kind of high-power lamp beads made of multiple chips on the market 10w50w, I think this kind of 10w50w is unreliable, relatively speaking, this kind of heat dissipation area is small, light decay is large, and the life is short.

We are doing lighting, and white LEDs generally ask about its luminous flux lm value, color temperature, attenuation, and color rendering index.

The main parameters of white LEDs are:

1. Electrical parameters: forward voltage drop, reverse withstand voltage, forward current, reverse current, maximum allowable dissipated power;

2. Light parameters: luminous intensity, color temperature, viewing angle, color rendering index, light decay;

When selecting, it is generally necessary to pay attention to the forward voltage drop, forward current, maximum allowable dissipated power, luminous intensity, color temperature, and light decay.

Optical parameters (spectral distribution, luminous flux, radiant power, color coordinates, color temperature, color rendering index), electrical parameters (forward voltage, current, power), thermal performance parameters (junction temperature, thermal resistance, shell temperature); and optoelectronic performance parameters under different heat dissipation conditions.

Power, brightness, turning on voltage. You understand that and you'll be able to deal with them.

Luminous flux or luminous effect or lux.

Color temperature, which is important for white light skinning.

In the case of in-line products, there is also brightness.

The main thing is the color temperature, and the light decay.
