What do you think the LED ball steep light quality stand or fall
what do you think the LED ball steep light quality stand or fall? First, see brightness
incandescent lamp wattage and don't speak only commonly lumens, LED bulb wattage lamp although also can use to calculate, but because of the LED lights in the unceasing development, the wattage and do not represent the number of lumens. Incandescent lamp I used wattage is generally divided into 15 w, 30 w and 45 w, 60 w, 75 w, 100 w, etc. If the incandescent lamp lumens count in do to business accounting, incandescent lamp luminous power in 7. 5 - 12lm/W。 The higher the wattage, the more power. Specific incandescent and LED bulb light power conversion is as follows:
3 * 1 wled power in four - ball steep light practice 4. About 5 w about alternative = 12 w energy-saving lamps around = 30 w bulb
5 * 1 wled ball steep light power in 6 - practice 6. About 5 w about alternative = 20 w incandescent light bulbs, energy-saving lamps of 45 w =
7 * 1 wled ball steep light power in 8 - practice 8. About 5 w to replace the energy-saving light of 30 w = = 75 w bulb
incandescent lamp is usually pear-shaped, so the ball bubble lights should also be pear-shaped. This is very simple, can do it. Incandescent light bulbs, but for the whole glass products, LED because demand for cooling, aluminum alloy is generally selected as a case, because capital is low, simple processing, and good thermal conductivity. Heat dissipation aluminum shell of intrusive, resolution, is also a good resolution.
the third, the ball bubble lights bubble shell
the so-called blister is lit in front of the glass shell. In the incandescent lamp, all of them are made of glass. But in LED bulb light, although also can do the blister with glass, but rarely do. 。 Because the weight of the LED ball steep light than incandescent bulbs weighs more than five times the speed, if made from glass, fell to the ground, breaking the possibility is very big. So more LED ball steep light to choose plastic bubble shell, in case of broken. And LED bulb light because the heat went out of the radiator, so after the blister of everbright is visible light, there are few hot infrared, so choose plastic to make the blister will not because of does not damage the radiator. General requirement for the blister is the following:
1. High pervious to light, high dispersion, no glare, no light.
2。 The light source is better concealment ( As far as possible, don't see the LED lamp bead) 。
3。 Light transmittance to reach more than 90%.
4。 With high flame retardancy.
5。 With high impact strength.
4, see light beads
the more famous lamp bead brands are: wafer ( Taiwan) , samsung, South Korea) ，CREE( The United States) Osram ( Germany) Such as import lamp bead. We can see on the packaging of the product specifications, high quality LED bulb lights are commonly use imported lamp bead.
5, after-sales service
stated above, we can identify a LED ball steep light quality, coupled with the price on the market, we can find a good LED bulb light.
