Application cases of high voltage linear IC00A8 in high voltage lamps

Yan Mingke has grown more than a year in the lamp tape, can the high voltage linear IC00A8 have the effect of the project light strip? The engineering light strip requires stability, reliable, no dead lamp, long life working time, the surface temperature of the lamp belt is low, can resist 265V high pressure work, etc. ----- 1: Reduce the use of the entire light strip, about 40 ° around the lamp belt under normal temperature (in the extreme working state, the chip temperature is ensured at 75 °, fully satisfying the temperature resistance of the lamp belt) Wen 80 ° Use the limit of use), so that the quality of the engineering light strip is more stable and extended, some customers play the engineering lights for two years, and the slogan of the three years! ---- 2: High-voltage linear IC00A8 unique constant current characteristics (current clamp) protection lamp beads work in a reasonable set current range (adjusted by peripheral resistance), so that it is not affected by the input voltage The impact caused by the beads, the phenomenon of dead lamp, making the engineering light strip more stable! ----- 3: High-voltage linear IC00A8 is not afraid of high voltage input and fluctuations, unique precision current clamping functions make the light strip to work in the input voltage environment of 250-300V - because the interior of the chip has detection exceptions The voltage thus starts the protection of the protection, so that it has downside, reaches the normal use of the protective lamp tape! ---- 4: Realize high light effect, using the light-efficient data of 60-80LM / W using normal resistance, using our 钲钲科 Electronic high voltage linear IC00A8 high-voltage constant current chip can bring you Equipment of 110-135LM / W. ------ For example, we do 4.2 watts (no frequency flash belt), can bring you about 530-550LM / W, and if it is a normal resistor program to achieve this If you like a dragon, the basic power needs to do about 7-10 watts. ----- 5: Our light-bead power utilization can be as high as 90% (Make the Solution of the Frequency Flash Belt) and 45% (the exclusive flash high PF scheme used by ordinary bridge bile plug), and ordinary resistance lamp With the impact caused by worry about working voltage to the lamp beads and resistors can only choose Big Niu La trolley ---- use high power (20-30 watts of lamp or 50-60 tile lights) Small power (output is generally 5-8 watts or 8-12 watts) Let's take a look at the specific case: From the above data, nearly 134.3LM / W low voltage 200V input light flux is nearly 470LM 9V lamp beads 30C4B high pressure constant current lamp with scheme Figure 1 9V lamp beads 30C3B high pressure constant current lamp tape scheme Figure 2 3V lamp beads 86C3B high pressure constant current engineering light strip effect diagram 3 This is the loss temperature data of the chip naked test. When the chip is affected by 0.24 watt, the chip surface temperature 61.7 ° chip surface temperature is 65.4 ° These data is a premise guarantee for the stability of the light strip! Read more
