LED lights do not know when it has been universal to people's daily life, has become a necessity of indoor lighting decoration, led lights small size, low power consumption, long life, has become a necessary factor to choose it, but the LED lights are divided into lights Beads and patch area of the two forms, then the difference between LED lamp beads and patch you are clear? Do not know it does not matter, today Xiaobian give you an analysis of led lamp beads and patch difference.
Speaking of LED lamp beads and patch the difference, we must first give you about LED lamp beads and patch are what? What are their characteristics? So that we can more clearly know the difference between LED lamp beads and patch is what.
LED lamp beads and patch of the difference between the LED lamp beads introduced
LED lamp beads is a light-emitting diode, belonging to the discharge of light, the use of low-voltage power supply, are safe power, especially suitable for use in public places; for current demand is low, between 0-15mA, the luminous brightness will be based on current Increase and brighten; and LED lamp beads for the variable environment, because the LED chip is very small, can be made into a variety of shapes of the device; the most important LED lamp beads response time is very fast, no environmental protection, no mercury Kind of harmful metals; In addition, LED lamp beads can be adapted according to the current color Oh, can turn into red, orange, yellow, green and other colored light.
LED lamp beads and patch of the difference between the LED patch
LED patch is also called SMD LED, belonging to the cold light, so life than the ordinary tungsten bulb 50-100 times longer; for the response time, the request is also very short, faster than the average light; and LWD paste Chip power consumption is very low, because the electro-optical conversion efficiency is relatively high, can further save energy; the most important LED patch has a high shock resistance, very reliable, the system operating costs are low; In addition, LED patch Small size, relatively thin, light weight, there is no shape restrictions, especially easy to create a variety of life should be.
LED lamp beads and patch difference summary
Through the LED lamp beads and patch of the elaboration, I believe you LED lamp beads and patch the difference with the basic understanding, the following we give you a summary of LED lamp beads and patch difference:
1. angle: LED lamp beads to do the angle is very small, are relatively concentrated light, the range is very far, but the limited range of exposure; and LED patch of the general angle to do a lot, are more scattered light, irradiation range Wide, but relatively close range.
2. Light principle: LED lamp beads are used to discharge light, and LED patch used in cold light.
3. Seismic resistance: LED lamp beads of the shock resistance as LED patch of good shock resistance.
4. Light color: LED lamp beads can be issued red, orange, yellow, green board a variety of colors of light, and LED patch does not have this ability.
5. Environmental protection features: LED lamp beads no mercury this harmful metal, compared to the next, environmental protection LED patch is not good enough.
led lamp beads and patch classification
1, in-line LED
Electrical connection to take 2-pin in-line form, is the traditional, low-end products, because the package heat resistance, chip cooling is not easy, so the light attenuation fast, short life. The advantage is cheap, can be made into a small light angle.
2, TOPLED
Electrical connection to take 2, 4 or 6 pin patch, is the current commonly used light source. According to the size of the package shape, divided into 0805,1206,3528,3535,5050,5060 and other specifications, the larger the package shape, the better the thermal performance, can withstand the corresponding power is also greater, the more light output.
3, piranha
Is a 4-pin lead-in package, cooling performance and reliability are better than ordinary 2-pin inline, can withstand 50 ~ 70mA of operating current, the current commonly used light source.
4, high power LED
The use of large-size chips and enhanced thermal channel technology design and production of LED, usually divided into 0.5W1W3W5W and other specifications, a single 1WLED can withstand more than 300mA of current, and output more than 100 lumens of luminous flux, widely used in commercial commercial lighting, traffic Control, photography, night vision and other fields. High-power LED prices are still high, with the technology gradually mature, it will hope to completely replace the traditional lighting source, leading the world into a solid light source era.
