Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate

LED work environment refers to the external work room temperature, LED lamps also have a working temperature, general LED lamp in the case of work, the external temperature is below 65 degrees is normal.

Q:Where can LED bulb be used?

LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection.

Q:What are the driving IC used in LED bulb?

Commonly used LED driver is based on the number of different W set, and now out of the drive program are quite a lot, according to customer requirements will also limit the number of different drivers IC.

Q:Ordinary lamp LED bulb can?

No problem, the heating LED bulb is mainly aluminum shell above on the lamp body, a lamp holder will not affect the interface, and the heating temperature does not exceed 60 degrees, and the plastic cap interface at least 160 degrees above the melting point, so is not affected on the lamp interface, you can rest assured that use

Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?

The difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.

Q:What's the cause of the noise during the aging of LED bulb bulbs?

This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.

Q:What is the AC voltage of the LED bulb?

LED lamp or constant voltage drive, generally through the drive circuit filter rectifier, LED bulb bulb AC voltage is generally 220V, power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.

Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!

The most direct and simplest answer is the power problem.

Q:What advantages does LED bulb replace energy saving lamp?

LED lamp structure is strong, green environmental protection, not easy to destroy, long life (generally 5 years is not a problem), this is energy-saving lamps can not be compared

Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?

In the integration sphere measurement, there is no standard lamp to proofread, or something else in the interior affects the measurement result, for example, the color of the lamp body itself will affect the color temperature more or less. Single color beads, chip on the aluminum base?
