6 FAQs about [High power lamp beads directly connected to the battery]
Why do LED lamp beads have a low power wattage?
In addition, the current can control the brightness of the LED lamp bead. In other words, LED lamp beads just convert electrical energy into light energy. There are four reasons for the attenuation of low-power LEDs: 1) The iron bracket has poor heat conduction. 2) Epoxy yellowing.
What is LED lamp bead?
LED English is (light emitting diode), LED lamp bead is the abbreviation LED for light emitting diode, which is a popular name. The terminal voltage of the PN junction constitutes a certain potential barrier. When a forward bias voltage is applied, the potential barrier drops, and the majority carriers in the P and N regions diffuse to each other.
Can LED lamp beads be used for LED lighting?
Generally, only LED lamp beads with an antistatic value greater than 700V can be used for LED lighting. LED lamp beads are unidirectional conductive luminous bodies. If there is a reverse current, it is called leakage. LED lamp beads with large leakage current have short life and low price.
Is a LED lamp bead a diode?
In fact, it is neither. The LED lamp bead is a diode. It needs a positive turn-on voltage to work, usually 2-3.5V. In addition, the current can control the brightness of the LED lamp bead. In other words, LED lamp beads just convert electrical energy into light energy.
What is the brightness of LED lamp beads?
The brightness of LED lamp beads is different, and the price is different. Lamp beads: general brightness is 60-70 lm; Bulb light: general brightness is 80-90 lm. 1W red light, the brightness is generally 30-40 lm; 1W green light, the brightness is generally 60-80 lm; 1W yellow light, the brightness is generally 30-50 lm;
What is a high-power LED light source?
The high-power LED light source is round and the packaging method is basically the same as that of SMD patches. However, it is essentially different from SMD patches in terms of use conditions/environment/effects. There are 0.06W, 0.08W, 0.2W, 0.5W, etc. for low power, and 1W, 3W, etc. for high power.
