Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?
PC Ivory lampshade, because of the low price, it is recommended to use light diffusion cover, so this should not be the problem
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!
Can reach 90% of the light, can not see the inside of the lamp
Q:What does "A19" mean in LED A19 bulb?
I'm studying too! There's a problem for everyone to discuss
Q:LED what are the bulb screws?
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: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:What are the types of LED bulb?
According to the interface, the LED bulb has GU10, E14, E27, E40 and so on.
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.
Q:Who knows where the broken LED bulb is?
The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
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 working environment temperature refers to the temperature of the air in the LED bulb, not the temperature of the aluminum substrate. The temperature of the aluminum substrate will rise as the LED lights up, and rise to a certain extent, which will involve the highest environmental temperature.
Q:Can the bulb's true life reach 30000~50000 by LED?
The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
