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:Secret LED bulb bubble price difference why so big?
Lamp beads。 I also do with Samsung bulb, bulb, lamp light cost more than others product price;
Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
LED is the most important heat, light will not be so serious, the thermal conductivity is relatively high Aluminum Alloy, so LED manufacturers usually choose to use aluminum shell
Q:How does the LED bulb go with the power?
voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,
Q:Are there any differences between negative ion bulb and LED bulb?
The negative ion belongs to bullshit type, the concept of things!
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!
Delays generally do not exceed 1S. After rectification, the capacitor is charged to the IC VCC terminal through the starting resistance. When the starting voltage of the IC is reached, the output switch pulse signal of IC is LED, and the luminous work is realized.. That is to say, the greater the capacitance, the longer the delay.
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind
Q:How to choose the bulb power?
The basic types of bulb power are divided into two types: isolated and non isolated
Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?
The diameter is 60mm, but the total length of each company is not the same
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Dielectric strength: electrical endurance test (resistance test) followed by insulation resistance test. During testing, the following AC voltage is applied at the specified position 1min. Type HV (220~250V); 4000V (RMS), BV (100~120V); 2U (rated voltage) +1000v.
