Advantages and disadvantages of multi-core high-power LED integration and single-core LED street lamps
 Multi-core high-power LED street light
   Â
advantage
1. The lamp housing is made of aluminum alloy die-casting, which can effectively dissipate heat, waterproof and dustproof. The surface of the luminaire is UV and corrosion resistant, and the overall luminaire meets the IP65 standard;
2, no bad glare, no stroboscopic. It eliminates the glare, visual fatigue and line-of-sight interference caused by the bad glare of ordinary street lamps, and improves the safety of driving;
3. The integrated design of the radiator and the lamp housing, the LED is directly connected with the outer casing, and the heat dissipation of the air-cooling wing and the air convection through the outer casing fully guarantees the service life of the LED street lamp .
4. The single elliptical reflecting cavity is designed with the spherical orphan plane to specifically control the light emitted by the LED within the required range, which improves the uniformity of the light output effect of the lamp and the utilization rate of the light energy.
5. The number of chips per unit area can be flexibly designed, and can be packaged into different point light sources or surface light sources as needed.
6, through different combinations can adapt to different voltages and currents, adapt to the driver design, thereby improving the overall light efficiency
Disadvantages:
1, Â Â Â Â Â Â Â Â Â Â Â LED packaging process is complicated
2, Â Â Â Â Â Â Â Â Â Â Â The multi-core integrated heat is too concentrated, and an efficient heat-dissipating housing is required. Otherwise, the LED light is seriously degraded, which affects its service life.
3, Â Â Â Â Â Â Â Â Â Â Â The concentration of light is concentrated, and the LED has low luminous efficiency. Currently, it is about 85LM/W.
4, Â Â Â Â Â Â Â Â Â Â Â With multi-core strings combined with circuits, the probability of reliability problems with single-core packages is large.
Single core LED street light

advantage
1. The lamp shell is formed by extruded aluminum, and both ends are die-casted. The high-transmission glass can effectively dissipate heat, waterproof and dustproof. The surface of the lamp is oxidized, UV-resistant and anti-corrosive, and the overall lamp meets the IP65 standard;
2, no bad glare, no stroboscopic, eliminate the glare, visual fatigue and line-of-sight interference caused by the bad glare of ordinary street lamps, improve the safety of driving;
3. The integrated design of the heat sink and the lamp housing, the LED is directly connected with the aluminum substrate , and the aluminum substrate is closely connected with the outer casing by using the high-efficiency thermal conductivity silicone grease, and the heat dissipation wing and the air convection heat are radiated through the outer casing, thereby fully ensuring the use of the LED street lamp. life.
4, using a single reflective material or lens, specifically control the light emitted by the LED within the required range, improve the uniformity of the light output effect of the lamp and the utilization of light energy.
5. The power is modular and flexible, and it can realize 42W-200W and other power lamps.
6. A single LED occupies a certain heat dissipation area, the temperature of the heat sink is uniform, the heat conduction effect is high, and the light decay is small, which ensures the service life of the LED street lamp.
7, can increase the corresponding components on the aluminum substrate, greatly reducing the probability of reliability problems, a quality problem will not affect the normal operation of other LEDs.
8, LED's luminous efficiency is high, the initial light effect can reach 110LM/W
Disadvantage
1, Â Â Â Â Â Â Â Â Â Â Â The whole lamp has high cost and is difficult to disassemble when processing and production.
2, Â Â Â Â Â Â Â Â Â Â Â The lamps are bulky and heavy.
3, Â Â Â Â Â Â Â Â Â Â Â The irradiation area is large, and it is not easy to achieve concentrating.
