Q:Seeking the production process of LED bulb... Thanks
First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
Q:Led what's the flash of the bulb?
The internal drive of a cheap LED bulb is generally a resistance drop, and voltage fluctuations can occur in a flash. So all 100 of you are a flash.
Q:What's the reason for the LED bulb strobe?
Currently on the market with single stage PFC driver circuit, there will be strobe, causing the flash because the ripple is too large. Single stage pFC circuits are not possible
Q:Why can't the voice switch control the time of the LED bulb?
The power of LED bulb is much less than that of incandescent lamp, and the control loop and light bulb of simple sound control lamp are connected in series, and the load is different and the time delay is different
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:Are there any differences between negative ion bulb and LED bulb?
Negative ions should belong to traditional lighting technology, LED is the latest lighting technology
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
It's best to use heat conductive glue, such as ST922.
Q:What advantages does LED bulb replace energy saving lamp?
The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond
Q:LED thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
Q:What's the reason why LED bulb gets a lot of heat?
LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different
