Information

Best module street lamp is a new type of road lighting product. It has the characteristics of high efficiency, energy saving, stability and reliability. The luminous efficiency is several times higher than that of the high pressure sodium lamp used in traditional road lighting. The lamp has a long life, low power consumption, and light decay. Smaller, the brightness remains unchanged after a year, and it saves more than 60% energy than ordinary street lamps. It is an ideal lighting choice. Do you know what design requirements it has?

Best module street lamp

In the market, the common Best module street lamp power supply adopts constant current power supply, which is determined by the characteristics of LED lighting materials. These materials are greatly affected by the environment, and long-term operation exceeding the rated current will greatly shorten the life of the lamp beads, and The constant current power supply can play a role in ensuring the stability of the current. The best module street lamp design has the following requirements: The main feature of lighting LEDs is the function of directional emission of light, because almost all power LEDs are equipped with reflectors, and the efficiency of such reflectors is significantly higher than that of lamps and lanterns. . In addition, the efficiency of the self-reflector has been included in the light efficiency detection of the LED. Road lamps using LEDs should make use of the directional light emission characteristics of LEDs as much as possible, so that each LED in the road lamps directly emits light to each area of ​​the illuminated road, and then uses the auxiliary light distribution of the lamp reflector to achieve A very reasonable comprehensive light distribution of road lamps.

It should be said that to truly meet the illuminance and illuminance uniformity requirements of CJJ45-2006, CIE31 and CIE115 standards, the lamps and lanterns should contain the function of three light distribution to achieve better realization. The LED with a reflector and a reasonable beam output angle itself has a good primary light distribution function. In the lamp, the installation position of each LED and the direction of the emitted light can be designed according to the height of the street lamp and the width of the road, and a good secondary light distribution function can be achieved. The reflector in such lamps is only used as an auxiliary three-time light distribution method to ensure better uniformity of road illumination.

The power supply system of the Best module street lamp is also different from the traditional light source. The constant current drive power required by the LED is a cornerstone to ensure its normal operation. The simple switching power supply scheme often brings damage to the LED device. How to make a group of LEDs tightly packed together safe is also an indicator to investigate the Best module street lamp. The requirement of the LED for the drive circuit is to ensure the characteristics of constant current output. Because the junction voltage changes relatively small area when the LED is working in the forward direction, so the constant LED drive current is guaranteed, which basically guarantees the constant LED output power. For the current situation of unstable power supply voltage supply in our country, it is very necessary for the driving circuit of road lighting LED to have constant current output characteristics, which can ensure constant light output and prevent over-power operation of LEDs.
