Cost benefit analysis of LED lamp tubes

1, three core requirements (brightness, power saving rate, life) determine LED lamp positioning

The main demand of lighting energy saving renovation in public area is the brightness, power saving performance and life of LED lamp tubes. The fundamental purpose of the project management is to create energy saving benefits. Therefore, of course, lamps with higher energy saving rate and longer life can meet the renovation needs.

Lighting r & D and production of a series of LED lamps in the industry with high light efficiency, long life (long warranty life) known, many actual transformation cases is a good proof!

2. Cost determines product performance

LED lamp tube to achieve higher light efficiency, more energy saving, longer service life, product design should have higher requirements!

tape lighting manufacturer on the power supply first USES the independent patent of high reliability, long life and high efficiency drive circuit, the power efficiency is as high as 94.8% above (i.e. the consumption of the whole lamp power more than 94.8% of the part on the LED lamp bead light, the rest are usually in the form of heat consumed), and most of the industry is using switch power LED lamps and lanterns, This technical indicator is only around 89%-91%. We also have higher technical requirements on the material selection of power components. For example, capacitors are generally required to refer to the industry standard of 1000V in the voltage test, while we require suppliers to do 2500V. The higher voltage resistance requirements can ensure better resistance of the components under extreme harsh conditions. Thus, the service life of the finished lamps can reach more than 5 years in some environments with large fluctuation of power grid voltage.

LED lamps and lanterns on the selection of LED lamp bead chips or adopt large size wafer can be equated to the performance of wafer chip domestic high-quality chips, stents must be high quality copper, gold thread within the lamp bead for pure gold (fine) line, bare lamp bead light efficiency in more than 190 lm/W, and we in terms of the number of lights, will also set aside sufficient margin, For example, a 1.2 meter T8 LED lamp tube, peer practice is 85 LED

Lamp bead, each power is 0.2W, the full load power of the lamp bead is 85*0.2=17W, general manufacturers are the whole lamp power to 16W-18W, basically used more than 100% of the full load power of the lamp bead, such a short time can not see anything wrong, but in half a year and a year later found that the light decline of the whole lamp is very serious, because each lamp bead load is large, Large current, large heat accumulation, light decay fast! The practice of lighting LED lamps is to use more than 96 beads, the power of each bead is 0.5W, the full load power of the beads is 96*0.5=48W, and the actual power of the whole lamp is only 9W, accounting for less than 18% of the full load power. This ensures that the beads basically work in a state of low current, less heat accumulation, light decay more slowly!

LED lamps and lanterns using the drive circuit with a unique lamp bead arrangement, in the anti-surge ability of lamps and lanterns performance is more outstanding, the laboratory has been aging test switch times reached 5 million times, power supply, lamp beads are still working properly!

LED lamps and lanterns in the selection of shell accessories, also give full consideration to the heat dissipation, light transmittance, and the safety of all aspects of demand, such as led tape lighting (normally on) the shell is made of high quality aluminum as the base and meet the demand of heat dissipation, mask is made of high quality PC diffusion, meet the light distribution and the demand of high light transmittance and no glare.

The above points, are built on a certain cost basis above the design requirements, so the cost determines the performance of the final product!

3, good products determine energy saving benefits

Compared with the ordinary first-line brands on the market, LED9W lighting tube can directly replace the 16-22wled tube of the first-line brands on the market, saving electricity in 50%, under the use conditions of the 24-hour working system, saving electricity :(18-9)W×24 hours ×365 days ÷1000kWh=78.84 KWH, The whole life cycle more energy saving (18-9)W×50000÷1000kWh=450 KWH; In addition to saving 450 degrees of electricity, ordinary tubes can top the life of three first-line brands of glass tubes on the market.
