- 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:LED can the bulb be used in the bathroom?
- of couse Yes, but LED kitchen and toilet light is recommended
- Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
- LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
- 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: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 the bulb is flashing. What's wrong with it? How do you fix it?
- There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!
- Q:LED how does the bulb return electricity?
- A 0 ohm resistor with a large point on the negative electrode
- Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
- 3, the monomer minimum power is different. Incandescent power is a common monomer, 15W, energy-saving lamps common power 8W, and then low lighting effect is not good, and LED lamp monomer minimum power is very low, can be less than 1W.The luminescence principle of
- Q:How to choose the bulb power?
- 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. Have the advantage of all LED lamps and lanterns:1, energy saving, environmental protection;2, long service life;3 、 no strobe, green.
- Q:What does "A19" mean in LED A19 bulb?
- A represents the bubble type, A hemisphere bubble 19, and the back figure indicates the bubble size (mm in diameter)
