1. What are 5730 monochrome SMD LED lamp beads? 5730 single-color patch LED lamp beads, as the name suggests, are named after the specifications of the lamp beads, namely: 5.7 (length) * 3.0 (width) * 0.8 (thickness) mm, currently most of the 5730 single-color patches produced on the market LED lamp beads, power 0.5W, current 150MA, voltage 3.0-3.4V. At present, there are also high-voltage lamp beads on the market. 5730 single-color SMD LED lamp bead is a kind of SMD, also known as 5730 SMD lamp bead. 2. Comparison of LED lamps and existing lamps With the continuous development of LED chip technology, lamp bead technology is also constantly improving and developing. 5730 monochromatic lamp bead patch has the advantages of high brightness, high color rendering index, long life, low carbon and environmental protection, power saving, no ultraviolet and infrared radiation and so on. In the past, incandescent and fluorescent lamps began to slowly fade out of sight. Reasons for eliminating them include high power consumption, strong UV light, low brightness, short lifespan and danger. Therefore, products such as incandescent lamps and fluorescent lamps are gradually being phased out. Since the products are in the season of replacement of the old and the new, the market competition is very fierce, and the price war has become a means of survival for the merchants. 3. Advantages and uses of 5730 single-color SMD LED lamp beads: 5730 single-color SMD LED lamp beads have complete color temperature, high brightness, high color rendering, and luminous efficiency. At present, the most widely used lamps of 5730 SMD are: Lighting fixtures such as bulbs, downlights, panel lights, fluorescent lamps, ceiling lamps, etc. The color temperature of the domestic market is mostly positive white light, that is, the color rendering index is not high, generally RA>70, which can be satisfied by the general high-end light-emitting diodes on the market. But for engineering lighting, the requirements may be higher. Engineering lighting not only has requirements for brightness and color rendering index, but also requires materials for engineering lighting. For example, the positive white temperature and color rendering index of 5730 lamp beads should be above 80, and the brightness should be above 55LM or higher. There will also be requirements for materials, such as what chip is used, is it gold wire, and what is the silica gel used for? Compared with engineering lighting, home lighting does not have many requirements on materials, such as low prices in the market. It can be re-split and put on the market with iron wires, domestic low-cost small chips, domestic inferior silicone packaging or secondary spectroscopic products. The disadvantage is that the service life is short, the brightness is not high, it is easy to burn out when the voltage is unstable, or there are potential safety hazards.
