1, brightness disproportionation end to end: LED line (soft or hard light bar) is since operating voltage is lower, and operating current is big, distance, route
Loss is big, cause end to end voltage differences it is big, because route generallys use constant pressure working method, therefore directly produce brightness end to end not
One the phenomenon that, strong influence illuminating effect, is at present in the maximum pain spot of entire illuminating industry.
, difficult realize extension seamless over long distances: the problem of causing greatly just because of above-mentioned pressure drop, the general single most 5- in circuit
10 meters long (12V5 meters, 24V10 meters) increase difficulty of construction, strong influence application effect.
, centrally connected power supply relatively difficult to achieve: 5-10 meters of traditional scheme must be coupled an electric appliance, and product cost is high, construction cost
High, maintenance cost height.
4, quality hidden danger: traditional scheme is since pressure drop and line loss are larger, power supply head end voltage height and the big fever of loop current
Seriously, small, the big inequality of head and tail temperature difference of the small fever of the low loop current of terminal voltage easily leads to full section lamp bead overheat nigrescence of powering
Product quality is bad.
