Light Distribution Curve

Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount

Q: Can the bulb's true life reach 30000~50000 by LED?: The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.

Q: Seeking the production process of LED bulb... Thanks: 10 points, Baidu wants to be a LED engineer. LZ is a real budget man

Q: What's the cause of the noise during the aging of LED bulb bulbs?: Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.

Q: LED what kinds of screw bulbs are there?: LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 5-10 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no harmful substances such as mercury can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.

Q: LED bulb w can replace 40W incandescent lamp: The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm

Q: I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?: The second continued the problem: welding line, this work continued not done!

Q: What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!: Sandblasting can be transparent, light is not dazzling,But will still see the light...

Q: What does the LED bulb patch mean?: In order to obtain high power LED light source, high brightness, the manufacturers to power direction in LED chip and package design. At present, the LED package can withstand W power has emerged. For example, Norlux series of high-power LED packaging structure for the hexagonal aluminum plate as base (the conductive) multi chip combination. The base diameter of 31.75mm, light emitting area is located in the central part, a diameter of about mm (0.375 * 25.4), can accommodate 40 LED tube core, at the same time as the aluminum heat sink. This package uses conventional tube core combination of high density packaging, high luminous efficiency, low thermal resistance, high in light output power flow under high electric. Is a kind of promising LED solid state light source.

Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: Depending on your application and cost, there's no way to say which is absolutely good;If the occasion is appropriate and the cost is not urgent, buy a drive.
