How to choose high quality LED Tube light

LED Tube light home lighting and commercial lighting as a preferred light fixtures. LED Tube light so very hot market demand, manufacturers are also many, LED Tube product quality is difficult to distinguish, the price difference is very large. So how to judge what is good or bad quality LED lamp, and how to choose cost-effective products and manufacturers do?

The main components of the wholesale market LED tube light is:. LED light source, power supply, profiles, aluminum plate, PC lampshade and then the difference in the following packaging materials is the main reason affecting the price1.LED light

LED chip LED light source is a major factor in determining the price, the current market brands of chip CREE, OSRAM Nichia Samsung. Second-tier brand chips Epistar San'an based, there are other Huga Genesis Photonics Tekcore etc. Different brands of chips Price is a big difference, if it is the same brand of chip die size and brightness is not the same as the price difference is there. So we choose LED Tube light when the first thing to know is what brand of chip, chip size or brightness is how much, and CIR index.

Do LED Tube light most used on the market today is the chip type is SMD3528 SMD3014 SMD5730 SMD 4014 SMD2835. T8 led tube is mainly used SMD2835 chips. This is 0.2W lamp beads single brightness up 26-28LM, so theoretical value can reach 120-140LM / W, is higher than other models lamp beads price advantage. SMD2835 chip cooling good, bad light in continuous work 2000 hours later, still less than 1%. It is also looking less consistency clear spot ..

2.LED driver

LED Tube drivers are mainly constant and non-constant, isolated and non-isolated driver drives currently on the market the best drivers are certified isolating driven relatively inferior is RC Buck program. LED driving mass mainly from the following aspects:

(1) LED driver is certified, it belongs to isolated or non-isolated driver.

(2) Use the Power Range: general 85-265VAC 175-265VAC wide voltage power supply than the expensive, PF value> 0.9 than PF0 = 0.6 or so is better.

Isolation is generally good quality LED driver with high power factor and wide voltage drive, isolated driver the advantage of circuit design complexity, to avoid the risk of electric shock. The disadvantage is that the power efficiency will be reduced, high manufacturing costs.

(3) currently on the market use non-isolated drive up the advantages of non-isolated constant current source circuit design is simple, low manufacturing cost. Drawback is prone to high load power an electric shock.

(4) driver compatibility: compatible electronic sensors or sensor inductor has no stroboscopic phenomenon.

3. The housing profile structure

Now LED Tube are basically three sections: glass, all plastic, 1/2 low glass and full plastic tubes T8 led tube inexpensive cost drawback is poor thermal conductivity, the light fades serious 1/2 aluminum led... tube heat is good but the cost is relatively high. 1/2 oval aluminum led tube T8, circular T8, for Integration T8 LED TUBE. Either structure T8, we must pay special attention to the thickness of aluminum, aluminum heat the thicker the better, of course the price should be your general thickness is 0.7-1.0MM, thin material relatively cheap there 0.3-0.5MM, thin aluminum structure is not strong, easily deformed, heat is not good. In general texture heavier than T8 LED TUBE good quality light.

4. Other aspects

(1) Plug: plug rotatable and non-rotatable, the rotation of the cost of more expensive than non-rotatable.

(2) PC cover transmittance: generally transparent mask transmittance can reach 88-95%, white mask transmittance at 70-86%. If the LED tube light flux is not increased mask 2000lm, now give it with only 85 percent light transmittance cream mask, then it is only the actual flux 1700lm luminous flux. When he gave it with the light transmittance is 95% transparent mask, then it will have actual flux 1900lm. Transparent cover high transmittance, but there are drawbacks that the more dazzling light. Cream mask made out of light and color is very soft. Therefore, according to their preferences in different environments used to choose different masks

(3) aluminum plate: thermal conductivity of glass fiber PCB board is 20w / mk, thermal conductivity of aluminum is 200w / mk. Greater thermal conductivity, thermal conductivity, the better the heat transfer. Use aluminum plate heat betterIn conclusion led tube quality and length of life, depending on the rational allocation of chip, power supply, cooling and other aspects, some extent luminous efficiency of LED light tube, the better the quality, the better.
