The development of LED has experienced nearly a century of exploration and innovation, from the initial weak red light to today's efficient full-spectrum lighting, completely changed the way human light sources are used.
LED is short for light-emitting diode, It can be divided into various types according to the package type, power, and application scenario:
1)Classification by package form:
In-line LED (DIP LED)-traditional LED, such as 5mm, 3mm LED, used for indicators, neon lights, and so on.
Patch LED (SMD LED)-such as SMD 2835, 3528, 5050, 5730, etc., used in LED lamp strips, bulbs, displays, LED pool lighting, etc.
COB LED (Chip on Board)-multiple LED chips integrated on the substrate, high light efficiency, good heat dissipation, for spotlights, downlights, and so on.
High-Power LED (High-Power LED)-such as 1W, 3W, 5W LED, used for outdoor lighting, car lights, and so on.
Mini LED & Micro LED- ultra-small size for high-end displays (such as Apple Pro Display XDR).
2) Classification by application scenario:
General lighting LED -such as LED bulbs, panel lights, pool lighting;
Decorative LED- such as RGB strip, neon;
Automotive LED -such as headlights, day lights;
Industrial/medical LED -such as UV curing lamp, surgical lamp;
Display LED -such as LED screen, Mini LED TV
Direct-plug LED: used for indicator lights, neon lights
COB: used in spotlights, downlights
High-power LED: used in outdoor lighting, car lights
MINI LE: Applied to high-end display screens
At present, the development of LED technology is very mature, and there are very good LED chip suppliers at home and abroad, like CREE, OSRAM, MLS, San'an, etc. We can judge the quality of the LED chip from 3 aspects :
1)Specification:
Light efficiency (lm/W): the higher, the more energy saving (quality LED>120lm/W).
Color rendering index (CRI) : ≥80 (quality lamps ≥90, such as museum lighting).
Color temperature (CCT): 2700 K- 6500 K, selected according to demand (warm light/cold light).
Life (L70/B50): L70 represents the time of light decay to 70% (quality LED>50,000 hours)
2)Materials and processes:
Heat dissipation design: aluminum substrate, heat dissipation fin (affects life).
Drive power supply: constant current drive (avoid stroboscopic, such as bright white power supply).
Packaging process: LED chips from well-known brands (such as Cree, San'an) are more reliable.
3)Certifications:
Safety certification: CE, UL, RoHS (lead-free and non-toxic).
Energy Efficiency Certification: Energy Star
You can see that a good swimming pool lighting = good LED chip + good heat dissipation + good power supply.
Shenzhen Heguang Lighting Co., Ltd produced the high quality pool lamps with San'an high efficiency LED chips + excellent constant current drive circuit design+ good heat disspation structure, we always insist the quality first and continue to export good products to the market, we are aiming to be the top one brand pool light supplier in China!
