Q:What's the quality of the solar garden lamp?

Power supply efficiency of LED street lampThe input power minus the output power value of this parameter is particularly important, the greater the value of efficiency is low, it means that there is a large part of the input power is converted into heat emitted; if it is installed in the lamp will produce a very high temperature, a light effect of our LED plus than the heat that will produce higher temperature superposition.And all of our internal power electronic component life will decrease with the increase in temperature. So the efficiency is the most fundamental factor power life, efficiency is too low, otherwise the heat consumption in the power supply is too large. Non isolation efficiency is higher than the isolation type, generally more than 80% on it, but the efficiency and the light plate matching method related

Q:Brand solar garden lamp which is good?

First of all, in order to improve the utilization rate of street lamps in road lighting, the light intensity center of the luminaire inclines to a certain angle to the road direction, and the ideal condition is that the light intensity center falls on the central line of the road. Considering the street lights themselves and the horizontal direction, there will be about 10. The angle of elevation can be calculated according to the geometric two angle relation. The center of light intensity of the M luminaire should be shifted to the direction of the road by 15~20.. The lens is assembled on the LED bracket, and the high-power LED chip is fixed on the bracket. The surface of the lens can be plated with an antireflection film, and the cavity between the lens and the chip is encapsulated with high temperature silica gel to reduce the multiple reflections of the light in the cavity and refract directly through the lens.
