- Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
- If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)
- Q:How to choose the bulb power?
- Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.
- Q:What brand of LED bulb is good in quality?
- See shape. Incandescent bulbs are usually pear shaped, so the bulb should be pear shaped. That's easy to do. But incandescent lamps are all glass products, and because LED requires heat radiation, aluminum alloys are usually used as housings, because of their low cost, easy processing, and good thermal conductivity. The size of the aluminum shell determines the heat dissipation and also determines the life span.
- 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:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.
- 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:Are there any differences between negative ion bulb and LED bulb?
- LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
- 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?
- LED bulb lamp, are driven by a power of the ordinary small beads, driving is very simple only rectification, filtering, limiting the number of components is another large power SMD beads, this drive is more troublesome, SMT SMD components, and double plate, both have the element.
- Q:Choose which light bulb LED bulb is the healthiest
- For home use, you can select LED bulb below 8W, with a color temperature below 3500K
