Information
Characteristics of LED Light Source:
 
 
 
 
 
_Voltage: LED uses low-voltage power supply, power supply voltage is between 1.8 and 3.6V, according to different products, so it is a safer power supply than using high-voltage power supply, especially suitable for public places. _Efficiency: Energy consumption is 80% less than that of incandescent lamps with the same light efficiency   4．  光衰：随着科技的进步，光衰越来越小。 At present, the light attenuation of ordinary LED lamps within 1,000 hours can be really controlled within 5%, even after more than 1,000 hours, the light attenuation is very small. 5. Environmental protection: no radiation, no pollution, real environmental protection materials. LED products are generally exempt from inspection when exporting
 
 
 
 
 
Dimensional knowledge of LED chips:
 
 
 
 
 
According to the shape classification, chips are generally divided into wafers and squares. Among them, the wafer is relatively low-grade and its performance is not stable. Our company generally does not use the LED produced by the wafer; the square is generally measured by size, such as 12mil (1mil = 0.0254 square millimeter). Generally speaking, the larger the chip size, the higher the brightness of the same brand chip. Our company's most commonly used LED beads, red and yellow light in general 9-12 mil, white, blue and green light in general 12-14 mil, which is also the most commonly used chip on the market, if larger chips, brightness, although it can improve a lot, but the price of chips has greatly increased, which is why size chips are rarely used.
 
 
 
 
 
Common knowledge of LED color:
 
 
 
 
 
The different colours of LED are determined by the chips with different wavelengths. For example, red light chips are usually 620-630 nm (nanometer), green light chips are 527 nm, blue light chips are 470 nm, yellow light chips are 585 nm, and white light chips are also blue light chips, only adding appropriate amount to blue light chips. The phosphor glows white.
 
 
 
 
 
Classification of LED;
 
 
 
 
 
According to the size of power; can be divided into small power, high power (industry generally more than 0.5W lamp is called high-power lamp). According to the form: can be divided into direct insertion type and patch type. Straw cap LED can be divided into F3 (3mm when the lamp head is diameter), F5 (5mm when the lamp head is diameter); or according to the shape of the lamp head, it can be divided into boundless, thin, thick, round; according to whether the lamp head is transparent or not, it can be divided into transparent, foggy... More methods of subdivision are not enumerated. The above list is based on our frequent use. Piranha LED can also be divided into F3 according to the size of the lamp head. F5 can be divided into round head (i.e. the most commonly used piranha lamp) and flat head (this kind of head is very special, its luminous angle is close to 180 degrees, which is commonly used in situations requiring astigmatism). Small power patch LED can be divided into 0805, 1206, 2835, 3020, 3528, 50 according to the size of the lamp head. 50 or 5060 (5050 and 5060 are very small differences, naked eye is difficult to distinguish, not professional customers can be called according to his habits). Our company often uses 2835, 3528, 5050. High-power LED is generally divided by power, the common is 0.5W, 1W, 3W, 5W, our company commonly used is 1W.
 
 
 
 
 
Common knowledge of the number of chip of LED;
 
 
 
 
 
The most common use of the same LED lamp is only one chip, but under special circumstances, it can use two or up to four chips, such as: a straw hat lamp can use one or two chips (considering its small size, inconvenient heat dissipation, resulting in performance instability, generally only one or two chips); a piranha lamp can be used. With one, two, three, four chips, our company most commonly used is one and two chips; patch 3528 lamp can use one, two, three chips (our company often uses one, two elder brother chips), patch 5050 generally uses three chips, especially description; patch lamp with three chips is, there are two situations: 1, three chips of the face. The colour is exactly the same. 2. The three chips are red, green and blue, which we often call RGB lamps.
 
 
 
 
 
Viewing angle of LED;
 
 
 
 
 
The most common light-emitting angle of the direct-plug LED is 120 degrees, and the special one can be 45 degrees or 15 degrees. Our company's commonly used direct insertion type is generally 120 degrees, silicone lamp is 45 degrees, patch type is generally 120 degrees of light-emitting angle;
 
 
 
 
 
Common knowledge of voltage of LED;
 
 
 
 
 
A single low-power LED lamp (including plug-in or patch type). The current allowed on each chip should not be higher than 20 milliamperes; the current allowed on each dual-chip lamp should not be higher than 20 milliamperes; similarly, the current allowed on each three-chip lamp should not be higher than 60 milliamperes.
 
 
 
 
 
2. High-power LED, our company has adopted 1W, the maximum current allowed to pass through is 150 mA.
 
 
 
 
 
Common sense of LED intensity;
 
 
 
 
 
1. Candlelight, International Candlelight, Definition of Candela
 
 
 
 
 
At the standard atmospheric pressure of 101,325 Newtons per square metre, the absolute "black body" with an area equal to 1/60 square centimeters (i.e. an ideal object that absorbs all external light without reflecting) has a vertical luminous angle of 1 Candela when the solidification temperature of pure platinum (about 2042K) is 1769 degree C. Moreover, the three concepts of candlelight, international candlelight and Candela are different and should not be equated. In terms of quantity, 60 candles equals 58.8 international candles, and 1 candlelight of Hefner lamp equals 0.885 international candles or 0.919 candles.
 
 
 
 
 
2 Luminescent intensity and brightness: Luminescent intensity is abbreviated as light intensity. The international unit is candela (Candela) abbreviation cd. Lcd refers to the luminous flux emitted by the light source in the specified direction of the unit solid angle.
 
 
 
 
 
3 MCD value
 
 
 
 
 
Mcd value is an irregular term in the industry, because each manufacturer measured
