LED lawn light

At present, most lawn lamps use LED as the light source. LED lawn light has a long service life and can reach above 100,000 hours. The use voltage is low, and it is very suitable for use on solar lawn lamps. In particular, led skills have achieved their critical breakthroughs, and their characteristics have greatly improved in the past five years. At the same time, the price/performance ratio has also been greatly improved. Led by low-voltage DC power supply, its light source control cost is low, regulating light and dark, frequency switching is probably, and will not adversely affect the performance of led. Controlling color, changing the spread of light, and generating dynamic dreams are all approximate, so it is especially suitable for solar lawn lights. It has many inherent characteristics that can cause undesirable results if left unattended. However, the current luminous efficiency of selling led in the market can only reach 15lm/w, and can only reach the three-color primary color energy-saving lamp 1/3.
From the cost point of view, the current cost per lm: Sanzi Town color base color high-efficiency energy-saving lamps (including current) 0.022 yuan, 2002 f5mm white light led cost is 1.9~3.0 yuan, the current production per lm cost is high, the difference is very different . From the perspective of application life, the life of three-color primary color energy-saving lamps (including electronic ballasts) can reach 6000 hours, and led can reach 100,000 hours. From the appearance, the LED lawn light is a three-color primary color energy-saving lamp (including electronic Tens of times the ballast), but it is not actually a cloud.
Most of the solar lawn lamps are equipped with super bright white light led. It is less than 10,000 hours when the ultra-bright white light led light flux maintenance rate reaches 50% of the initial intensity under 20ma. The electric light source of Fudan University has proved this. . That is to say, LED is not the best solar lawn light source in many environments, unless it is a low-end, solar lawn lamp with a service life of only 1 to 2 years, which is about 1w or less of solar lawn light. For the solar lawn light above 1w, it is best to use a three-color base color energy-saving lamp. At present, there are some solar lawn lamps with 30~40 super bright white LEDs, and the input power is 2w. In this environment, if the three-color primary color energy-saving lamps are used, the cost is only 1/10 of the LED, and the luminous flux is the original. 4 times.
According to the above analysis, it is believed that there is a low-power solar lawn lamp below 1w that regulates the brightness and darkness of the switch. As usual, LED lawn light should be used as the light source. However, when applying super bright white light led, it is necessary to pay attention to the problem of lumen maintenance rate, otherwise it will easily lead to chaos. For the solar lawn lamp with high power, the current application of three-color base color high-efficiency energy-saving lamps is more reasonable. It should be emphasized here that the above conclusions are only the current analysis. When the level of led skills is raised, the cost falls, and the above conclusions must be changed.
To deal with solar lawn lights, considering the reliability, performance cost ratio, color temperature, and luminous efficiency, we think that the ideal light source should be a three-color primary color energy-saving lamp.
