[Text / Zhao Chunbo] "De-powered", although it has become a hot word in the LED lighting industry, but it has not been accurately defined, different people have different understanding. The “de-energization†accepted by most practitioners refers to the fact that in the LED lighting system, the driving circuit and the LED lamp bead share a substrate, so that the lamp driver is integrated, and the system solution of the independent power module is no longer needed. Called de-powered.
The de-energization scheme is not without a driving power supply, but generally does not require energy storage components such as transformers and inductors. The driver IC and peripheral components in the driving circuit can all be attached to the aluminum substrate, and the solution is simpler and easier to automate and batch. Production; at the same time, it can reduce the volume and reduce costs.
The “de-energization†solution eliminates the need for a separate power module, which not only reduces the size but also reduces the cost. At the same time, the cost of the LED lamp bead is reduced, and the overall cost of the “powering†solution is significantly reduced. Low cost is also an important reason for the rapid development of “de-energization†solutions.
The “de-energization†scheme can increase power by paralleling multiple identical units, which is easy to mass-produce; and with the difficulty of recruiting labor and the increase of labor costs, the “de-energized†scheme that can achieve almost all patches is naturally loved by many companies. Simple, easy-to-batch, and automated production are another important reason for the rapid development of “de-energized†solutions.
At the same time, the “de-energization†solution eliminates the need for transformers, inductors, and even some solutions without electrolytic capacitors. It has high reliability and long service life, and is also suitable for high-end markets.
For the “de-energization†solution, Mingwei Electronics has been continuously introducing new solutions. As early as 2012, Ming Microelectronics introduced a de-energized driver chip: a linear constant current driver SM2082 with over-temperature compensation, a SM2083 with 1-channel PWM dimming, and a SM2087 with high power factor.
In 2014, with the rapid development of intelligent lighting, Mingwei Electronics also launched the “de-energized†intelligent driving solution: SM2211E supporting switching constant power segmentation dimming or color grading; supporting 2/3 PWM dimming Technology, external modules such as: WIFI, RF, Zigbee and other intelligent dimming SM2123E/SM2133TE; support PF> 0.99, THD <15% low THD scheme SM2315E and so on.
At the same time, Mingwei Electronics is about to launch five/four/three-way RGB+ white yellow innovative intelligent linear drive products, using IIC protocol, PWM without stroboscopic.
SM2211E realizes the switch coloring "de-energization" scheme physical map compared to the traditional switching power supply intelligent scheme, the linear constant current drive realizes the de-energized intelligent scheme with low cost, small size, easy production, high integration, and interference components. Less, high reliability, is expected to accelerate the promotion and popularization of intelligent LED lighting. The light engine and HVCOB (drive circuit and LED lamp bead enclosed in a COB) are also a kind of "de-energization", and have become the new favorite of many practitioners.
Will the “de-energization†scheme completely replace the switching power supply scheme? the answer is negative. First of all, the “de-energization†scheme generally uses a high-voltage linear constant-current drive circuit, and the input range cannot achieve full-voltage (85~265Vac) input, which cannot be used in the market where the input power grid fluctuates greatly;
Secondly, although "de-energization" can achieve high power, the scheme is mostly a large voltage and small current scheme, and the cost of the large current scheme has no advantage. In addition, some people reject it from their hearts and do not accept the "de-energization" program.
At present, the “de-energization†scheme accounts for about 10% of the LED lighting market, mainly in the fields of bulbs, lamps and the like. With the reduction of the cost of LED lamp beads and the further development of de-energization technology, it is expected that in the next 1-2 years, de-power products can account for 30% or even 40% of the market.
In the field of application, it will extend to many fields such as medium and high power ceiling lamps, panel lamps and downlights. The “de-energization†solution will definitely become an indispensable force in the LED lighting driver market! Most of the schemes are large voltage and small current schemes, and the cost of large current schemes has no advantage.
