Whether it is ordinary LED or high-voltage LED, it is inevitable to face the problem of heat dissipation design and work reliability. However, many people have been paying attention to how to solve these problems.
From the perspective of cost and market, high-voltage LEDs are used as illumination sources, and LED device products are applied to street lamps. The special technical requirements are mainly to design LED light intensity and illumination angle. In addition, due to multiple LED combinations, light-emitting design In terms of illuminating the area, the luminaire needs to focus on the effectiveness of heat dissipation.
The main solutions for the comparison between high-voltage LED lamps and ordinary lamps are as follows:
Advantages: energy saving, environmental protection, easy to adapt to low voltage, and can also be directly matched with solar energy system, without additional inverter and conversion process, can achieve maximum energy utilization.
Insufficient: the illumination angle is small and uneven, the color rendering index is low, and the optical and heat dissipation design is complicated.
Technical deficiencies: The luminous flux under the current technology is not enough, the light efficiency is too low, and the quality is difficult to guarantee.
Solution: LED products need special design for street lamps, and special standards are required (using the test data of traditional light sources to evaluate led light sources is often not objective).
In short, the high-voltage LED is a characteristic LED that can increase the user's choice. In the solar-powered lighting system, it is originally a low-voltage DC power supply, of course, it will also directly use low-voltage DC LED. So all kinds of LEDs will exist, but only for different occasions.
