Q:The same power of cob and led lamp which is brighter
Taiwan chip is commonly used in single chip LED photosynthetic efficiency (commonly known as the single lamp) : 80 ~ 110 lm/W, under the same power chip, the greater the size (area) the higher light efficiency.
Q:How much time LED lamp life
LED the whole lamp life means establishing droop 30% of the time, the higher the temperature of the solder, the more serious the droop, at the same time because of the LED drive power components in the limited life (especially the electrolytic capacitors under high temperature electrolyte dry), so we all find balance in cooling costs and the temperature of lamps and lanterns
Q:The sitting room LED shoot the lamp to be more powerful
Sitting room (should consider its size) LED lamp as a decorative light, only 15 w can, but not commonly used as a lamp, can also according to individual hobby, optional much larger (more verve and high illuminance is often made exciting atmosphere, relaxation of low illumination is easy to build, friendly atmosphere), anyway, not consume too much power
Q:LED to shoot the light on when why?
LED lamp bead quality is bad, the power supply is not stable. Try suggested a change of power supply.
Q:What is main purpose of the LED lamp
Save electricity saving life is long Art effect is good The light is downy healthy variety does not hurt eyes
Q:What brand of shoot the lamp to LED lamp of choose and buy skills
See shoot the lamp wattage: giant shoots the lamp holder is every foot of W, 1 W, 3 W are common. Many small factory in order to compress costs, low-end can choose less than W lamp holder, nominal 1 W, some will use 0.75 W, even 0.5 W lamp holder. LED to shoot the light skills of choose and buy four: the lamp shade and light body 1. LED shoot the light of the lamp body and face mask. The best LED lamp body material for ceramic, so that the heat generated by the light of LED lamps and lanterns is able to even send out pass out, ensure the LED lamps and lanterns in the use fixed number of year is not easy because of excessive heat cause the damage of lamps and lanterns.
Q:The led lamp or built-in good external constant current driver
Good, external device is greater than the space without limit, you can do better, and the other heat dissipation is better, longer service life.
Q:LED to shoot the light, heat sink, aluminum alloy profiles and die casting aluminum radiator which is better?
Even better aluminum profile, material, wall thickness can be thinner, heat dissipation performance is better..
Q:Tube lamp, metal halide lamp, lamp, LED lamp, the difference between more than advice please!
Tube light is used for general lighting, can use energy-saving lamps and LED lights Metal halide lamp together not concentrated mostly see shape, but the metal halide lamp used for local lighting effect is very good, like a clothing store Than metal halide light that shoots the light is weak, but stronger than canister light LED just refers to the light source, with energy-saving lamps, incandescent light bulb is a concept
Q:The difference between led grille lamp and dared light
Dared light is usually a commonly known as the grille lamp, because the appearance of lamps and lanterns of the tank using light source similar to "fight" (old instruments of food), so also called dared lamp, also have called "the bean pot lamp", should be the harmonics. Dared light panel is made of high quality aluminum alloy profile, after spraying processing, flashing silver, rust and corrosion resistance
