Q:How to identify Ic constant current LED bulb?
Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
Q:How does the LED bulb go with the power?
Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V
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.
Q:LED thread specifications for bulb bulbs?
Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.
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?
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
The lamp is normal body temperature measurement temperature lamp, lamp heat sink temperature is the key, if the heat do good, heat sink temperature is close to the junction temperature, but the temperature are generally measured lamp pin temperature, plus a rise coefficient estimation of heat sink temperature, so as to estimate. The temperature of the lamp. The temperature of the aluminum substrate and the heat sink is relatively surface, and the superficial and relatively useful temperature depends on the junction temperature, which is related to the life of the LED. So the temperature near the pin or heat sink is more realistic.
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:What's the cause of the noise during the aging of LED bulb bulbs?
The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.
Q:LED how to classify bulb bulbs?See some LED bubble bulb specifications are written in A60, A45, and some are written G60, G45, I do not know, in addition to the maximum diameter of the same, what is the difference between the meaning of A and G?In addition, how can the whole LED bulb be classified, only by the maximum diameter, or with other classifications?,
LED bulb has two kinds of high power and small power, as well as color. High power bulb has a radiating fin from its shape. It is well recognized
Q:What does "A19" mean in LED A19 bulb?
A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
