LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

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: Ordinary lamp LED bulb can?
Yes, just buy a high voltage LED light bulb. Contact me. I'll send it to you from the factory
Q: LED bulb with what type of LED beads?
There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2
Q: How to choose the bulb power?
If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.
Q: Seeking the production process of LED bulb... Thanks
10 points, Baidu wants to be a LED engineer. LZ is a real budget man
Q: What's the reason for the LED bulb strobe?
Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.
Q: 60W how many lumens and how many W LED bulb does incandescent bulb replace?
100lM/W LED bulb, 4-5W can be replaced. If it is white 4W can be, if it is warm white (yellow light), preferably 5W, mainly human eye feeling, white light than Huang Guangliang.4-5W LED bulb, equivalent to 12-15W energy-saving lamps
Q: What does the LED bulb patch mean?
According to different applications, different size, cooling scheme and luminous effect of.LED packaging forms. At present, according to the classification of LED package are mainly Lamp-LED, TOP-LED, Side-LED, SMD-LED, High-Power-LED, Flip Chip-LED Lamp-LED (vertical LED) emerged in the early Lamp-LED is in line LED, it adopts the form of sealing packaging. The potting process is the first injection of liquid epoxy resin in LED molding cavity, and then insert the pressure LED bracket welding, in the oven make epoxy resin after curing, the LED from the cavity from the molding. Due to the relatively simple fabrication process, low cost, have a higher market share. (SMD-LED surface mount LED) patch LED is pasted on the surface of a wiring board, suitable for SMT processing, can be reflow, a good solution to the brightness, perspective, smoothness, consistency, reliability and other issues, the The lighter PCB plate and a reflecting layer material, improved to remove the carbon steel pin dip LED heavier, the display of epoxy resin less reflective layer needs to fill, to reduce the size, reduce the weight. In this way, the surface mount LED can easily reduce the weight of the final product in half, make the application more perfect.
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: Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
Plastic bulb lamp, I have done it myself, this gadget specializes in low-end market, it is recommended not to use, used well, used for a long time, used poorly, minutes of effort have to hang.
