Introduction of led ceiling lamp bead -LED patch lamp
LED SMD lamp is made of FPC circuit board, LED lamp and high-quality silicone sleeve. Good waterproof performance, safe and convenient use of low-voltage DC power supply, diverse and bright colors; Outdoor use can resist ultraviolet aging, yellowing and high temperature. This product is widely used in building outline lights, quasi-decorative lighting in entertainment places, advertising decorative lighting and other fields.
Product features:
1. It can be bent at will and fixed on the concave-convex surface at will.
2. Every two LED lamps can form a loop.
3. Small size and rich colors.
4. High brightness, adjustable lighting angle, and the installation and length can be customized as required.
5. Energy saving: constant current drive, ultra-low power consumption, electro-optical power close to 100%.
6. Environmental protection: no ultraviolet and infrared radiation, no heat and no danger of mercury leakage.
7. Long service life: 50,000-80,000 hours, which is more than 10 times the service life of traditional fluorescent lamps.
Led ceiling lamp bead-introduction of led lamp bead
LED English is (light? Distribute Diode)? LED lamp bead is the abbreviation of light emitting diode, which is a popular name.
1.？ Voltage: LED lamp beads use low-voltage power supply. What is the power supply voltage? 2-4V, which varies according to different products, so it is driven by a specific high-voltage power supply; Safer power supply, especially suitable for public places;
2. Current: The working current is 0- 15 mA, and the brightness becomes brighter with the increase of current.
3.？ Efficiency: Less energy consumption than incandescent lamps with the same light efficiency? 80%。
4.？ Applicability: Very small per unit? LED？ What's that little piece? 3-5 mm? Square, so it can be made into various shapes of devices, suitable for changing environments.
5.？ Response time: The response time of its incandescent lamp is millisecond. LED？ The response time of the lamp is nanosecond.
6.？ Environmental pollution: no harmful metal mercury.
7.？ Color: the color can be changed by changing the current, and the band structure and band gap of the material can be easily adjusted by chemical modification of LED, so as to realize multicolor luminescence of red, yellow, green, blue and orange. If it is red at a small current? LED？ With the increase of current, it can turn orange, yellow and finally green.
Led ceiling lamp bead -LED lamp piece or lamp bead?
1 is different from the power of LED lamp beads.
High-power LED lamps generally adopt 1W high-power LED lamp beads, 1-3W*** high-power LED lamp beads and COB high power. The maximum power of a single LED of high-power lamp bead can reach more than 200W W. ..
Low-power LED lamps generally use SMD bulbs, which mainly include the following types: 5050 bulbs, each 0.2W, 3528 bulbs, each 0.06W, 30 14 bulbs, each 0. 1W, 5630 bulbs, each 0.5W, and each 0.5730 bulbs.
2, the cost is different
From the perspective of product cost, the cost of high-power LED lamp beads is higher than that of low-power. First, the cost of high-power LED itself is high. Second, aluminum heat sinks should be added to high-power LEDs, and ordinary circuit boards should be used for low-power LEDs, so natural heat dissipation can meet the requirements.
3. Use different LED lights.
High-power LED is basically used in products that require high light source per unit area, such as LED ceiling lamp, LED projection lamp, LED bulb lamp, street lamp and so on.
Low-power LED is basically used for products with small patch area, difficult heat dissipation and low requirements for light source emission per unit area, such as LED ceiling lamp, LED fluorescent lamp, LED panel lamp, LED strip and so on.
On the whole, the patch is good. After all, in addition to good heat dissipation and large light angle, the reasonable design of the patch will make your light bulb have no dark areas. In contrast, lamp beads have no advantage.
So much for the above introduction about whether the led lamp is a good patch or a good lamp bead. I hope that through the above introduction, we can have a clearer understanding and understanding of the two technological methods of led lamps. Through the above comparison, we find that led SMD lamp is better than led lamp bead as a whole. However, according to different applications and environments, the two will still be different. As long as you observe carefully, you will find that led lights and beads will be used in general indoor lighting such as home environment and office environment, while led patch lights will be used outdoors.
