Horticutral Lighting
According to the actual use environment and the led flood light own features, the following points should be taken into consideration when selecting LED drive power supply
High reliability
especially like the led driver of LED Flood light, generally they are installed outside ,of course , maybe separate from the light fixture as well . such as hidden in the light pole or installed on the fixed bracket. We must comprehensively think of its waterproof ,aluminum housing and any other performances. High reliability led driver is not easy to break and help to reduce the cost of maintenance.
High efficiency LED flood light usually require high efficiency of led driver to adapt .
the luminous efficiency of LED decreases with the increase of LED temperature,so the heat dissipation of LED is very important . if the led driver is installed inside the light fixture structure. higher efficiency of led driver is needed here. The higher efficiency the led driver is ,the less heat it emit .That is to say , when the led driver is high ,its power loss is small, calorific value inside led flood light is small,thus reducing the temperature rise of led flood light . in this way we can keep this led flood light steady and reduce the negative impact because of temperature and delay LED light decline.
High power factor
the power factor is the load requirement of the power grid and is an important technical data of power system .it shows the efficiency of electrical equipment. If power factor is low . the reactive power of the circuit used for alternating magnetic field conversion will be large, which will reduce the utilization rate of equipment itself and will increase the power supply loss of the circuit. most of our led flood light have a wide range of power . our led flood light power factor is generally at a high level more than 0.92.when matching with led driver , corresponding power factor of the led driver is an significant data .
two common driving methods
one is constant voltage driver .the output voltage of Constant voltage driver in the allowable load is constant and it will not change with the change of the load . this driver is usually applied to the small power LED module. constant voltage is what we often say the steady voltage power, can ensure that the load (output current) changes, maintain the same voltage The other is constant current driver.While Constant current in the allowable load, the output current is constant, will not change with the change of the load, usually used in high-power LED , such as some excellent led flood light .
Surge protection
LED anti - surge ability is relatively poor, especially anti - reverse voltage ability.It is also important to strengthen protection in this regard.Some LED lights are installed outdoors, such as LED flood light.Due to the grid system will invade a variety of surge, some surge will lead to LED damage.Therefore, the LED driver should have the ability to inhibit the invasion of surge and protect the LED from damage.
LED temperature negative feedback
In addition to the normal protection function of the led driver, it is best to add LED temperature negative feedback in the constant current output to prevent LED temperature from being too high.
Basic Protection performance .
led driver also should be waterproof, moisture-proof, the shell to be sun-resistant.
Lifespan
The lifespan of the led driver should match its of LED flood light.
Safety regulations
Comply with safety regulations and electromagnetic compatibility requirements.
