LED lights use LED constant current is 20mA, therefore, must ensure that the current power supply can not be greater than the constant current. Many of my friends only pay attention when using the voltage, while ignoring the current specification, this often leads to too large because the supply current of the LED breakdown, damage caused by LED lights.
SMD LED Strip Light is mainly used for decorative purposes, as our major customers in China is the engineering installation company. Because of the SMD LED Strip Light is not very understanding, so a lot of customers will be quoted in the calculations when the number of missing links, give yourself some unnecessary additional costs. Here's to the company's products, for example to share with you how to calculate the SMD LED Strip Light project installation costs:
1, LED flexible strip length: for the project, calculate the required LED Strip's total length. It should be noted that LED bulbs can be divided in groups of three to cut the use of, the general per meter 60 LED's LED bulbs each length of 50mm, 30 LED per meter of LED bulbs each length of 100mm. Understanding of this effect after the construction design drawings based on actual need to use to calculate the number of LED bulbs. Generally reserved for the length of one meter is like a spare, so as to avoid excessive waste of resources procurement.
2, LED flexible light strip power: because the purchase of LED bulbs is not the power distribution, so calculate the required length of LED bulbs, the power required to calculate the power, and then match the power. Different LED bulbs of different power, so the match should carefully choose the power supply. Here are what the power LED Strip:
0603LED soft light: 12V, per meter 60 LED, per meter power 1.5W, per meter of constant current is 0.125A
1210LED soft light: 12V, per meter 60 LED, per meter power 4.8W, per meter of constant current is 0.4A
5050LED soft light: 12V, per meter 30 LED, per meter power 7.2W, per meter of constant current is 0.6A
5050LED soft light: 12V, per meter 60 LED, per meter power 14.4W, per meter of constant current is 1.2A
, such as buying 5050LED flexible strip, matching the power supply is 12V, 4A specifications, then a power supply with a 6 m 5050LED only soft light. Because 5050LED soft light power per meter is 7.2W, 6ç±³total of 43.2W, while the power of the rated power is 48W, the power is generally not recommended to use full capacity, because as a great influence for the power of life, it is recommended to use only the power supply of 95%. If you need 100 meters, then the corresponding 4A power you need with a minimum of 16.
3, LED flexible strip controller: for RGB flexible strip, it must be equipped with a controller to be effective, and a controller to control the LED flexible strip length from 5 m to 20 m, mainly to see the selection of what kind of specification of the controller. Thus, in the soft light of RGB after purchase, but also the length of the controller to control the number of additional purchase of the controller, or to purchase RGB amplifier (each amplifier can extend 5 meters). Do not mistakenly believe that a controller can achieve all the soft light of the RGB control requirements, this is the wrong point of view.
For example, to buy the 100-meter RGB Flexible Strip, and the controller is the conventional choice of controllers, each controller is the control that is 5 meters. Then 100 meters on the RGB flexible strip with 20 RGB controller needs, or buy an RGB controller, the other to buy 19 amps. LED lights use should be noted that the power voltage, current, power, these three factors are indispensable!
