 LED beads types and characteristics

 

 

 1. LED beads species

 


1 , straw hat lamp ( DIP ) , the specifications are 3mm, 5mm, 10mm. For : luminous three-dimensional characters with a light, thin light boxes backlight, showcase lighting, interior lighting, architectural lighting of the wall decoration , advertising signs , instead of neon lights, children's toys


2 , Piranha lights ( mainly supply flat head, riding series ) , the specifications are 8mm. For : Indoor Lighting: Spotlights , dome light / lamp , LED light bar ; automotive lighting : taillights / turn signal / brake light , automotive lighting ; advertising industry : Lightbox / background light, business / store signs , LED logo / acrylic plastic characters .


3 , SMD ( 3528 and 5050 ) , lumens (3.5LM-7.5LM and 17LM-18LM) were current ( 20 mA and 50 mA ) , power ( 0.04 watts and 0.192 watts ) . Mainly used in : 1 lighting ( general lighting and decorative lights, such as LED strip light, LED rope right, LED tube light.  ) 2 3 car electronic device indicator light .


4 power : chip larger particles , the power of 1 watt. Used in general lighting, signage, backlighting, indicator light , architectural lighting , installed . Decorative lighting, LED flashlight, portable lighting , lights, traffic lighting .

 

 

2. LED beads ( light-emitting diode )

 


From: Phosphor ( preferred foreign imports ) , the bracket ( copper ) , glue ( Japan preferred silicone ) , chips ( preferred Taiwan ) components. The basic color of the lamp beads include: red, green and blue chips including : wafer ( cheap, poor quality ) , the film ( expensive but good quality , 10 × 12 → 5 lumens , 45 × 45 → 90 ~ 110 lumens ) , The unit is mil.


Note: The price depends lumens lamp beads , while the color temperature (7000K or more was bluish , yellow candle was about 3000K , the office is usually 5000K) irrelevant .

 

 

3. LED advantages:

 


Brightness strong and stable lighting conditions , through 3V current can be used.

 


4. LED series features :

 


1, LED light source is 1W / 4 (7070) patch, chips imported from Taiwan , epoxy encapsulation. High brightness , light is small , light, soft, spot uniformity, under the same lighting effects, power consumption is only one-tenth of white bulbs , color temperature closer to natural light , no light pollution.


2, LED constant current source drives are used , according to the power one- commissioning, high impact resistance , by the short-circuit protection , wide input voltage (110-280V), more safe and durable.


3 , aluminum plates are made of high thickness ( up to 1.6mm ), high -purity aluminum oxide processing , better thermal conductivity, heat dissipation, light decay smaller.


4, LED circuit board design are combined with strings , more scientific and reasonable , the use of screws , not welded , maintenance is more simple and convenient.
