Design Defect of Existing Replacement Lamps
- Mar 23, 2017 -

Design of existing lighting the way what are the disadvantages?

1, heat sink

Poor heat LED is well known, Wick brings life problems. Existing design of LED lights tends to heat to meet the requirements, in an area cooling requirements are very demanding, but using a very poor way of passive cooling, and the majority are air cooled, even closed air cooling. Like the lamp driver Board and plastic casing should be added between aluminum fins to increase the reliability of insulation, thermal silica gel to increase the cooling capacity need irrigation. T8 lamps are closed, wicks had to rely on air convection heat to the back of the lamp on the aluminum tubes for cooling. Generally this type of lamp's internal temperature will have seventy or eighty degrees. And if both heat sinks, weight issues take into account weight, heat is difficult to guarantee it is a difficult choice in the existing design, there is no feasible standard.

2, life

Wick LED life exponentially decreases with the increase of temperature; Electrolytic Capacitor temperature increases 10-life is reduced by half; MOS temperature increases, resistance increases, loss increase, temperatures will rise again (constant-current mode), eventually burned to the ground. Of course, domestic manufacturers did not give a specific life of LED lamps, Wick publicity just mentioned LED life of 100,000 hours, LED the life of a bottleneck in the system driver Board, often LED the wick is not corrupt, the system drive has died.

3, weight

Spiral interface lamps, fluorescent lamp weighs only LED lighting ''>LED lighting one with no heatsink problems, weight of fluorescent lamp can be ignored, but the weight of the LED on the base is a very serious test, especially 7.8W Helix interface LED lights, its weight is dangerous, this point and which businesses considered the?

4, the price

Normal LED driver Board in the 70-degree temperatures may live only 5 years (domestic), far from Wick LED 10 "concept". Compared the same brightness of a fluorescent lamp, fluorescent light only 1 year of life, 1W1 fluorescent lamps than 1W10 Yuan LED far more cost-effective. Wick LED damaged lamp often in particular not as bad, but the whole lamp replaced. Reckon that as a one-tenth driver Board but dropped the remaining nine-tenths light (Wick and heat sinks the whole lamps most of the cost), if every manufacturer is not ready for recycling, the customer is not going to like this product.
