High power LED lamp selection
Dazzling array of market led high-power lamp products, each big enterprise in order to enhance the market competitiveness, increase market share, many enterprises also provides customized services, even so, many lighting companies, or do not choose high power LED lamp, because still exist some enterprises in order to reduce the cost, the false parameters to deceive customers, so lighting enterprises in the purchase of products, to detect the parameters of the products is very important, seamounts Hing Wai day adhering to the "good products, low prices, good service" management philosophy, adhere to the, to provide customers with the best quality products, to reassure customers will used to detect re cooperation.
High power LED lamp is generally chosen from the following 9 aspects to analyze
1, LED brightness
Generally speaking, the brightness of the LED is different, the price will be different, the higher the brightness, the higher the price. Shenzhen light source manufacturers in the supply of high power light source, 1W, 30-50lm, 80-120lm, 1W, 1W,, 30-50lm, 20-30lm, and 1W, the average intensity of the red light is generally.
Hailong Xing photoelectric provide large power light source in brightness are than other enterprises eclipsing, seamounts Xing photoelectric 1W red brightness 50-60lm, 1W green brightness for 120-130lm, 1W yellow brightness is 50 - 60lm and seamounts Xing Wei electric skylight in the production is white, warm white beads on has the advantage, brightness up 200lm/w.
LED lens: a lens generally with PMMA, PC, optical glass, silica gel (soft silica gel, silicone) and other materials. The higher the angle is, the higher the efficiency of the light, the light to shoot far, and the LED lens with a small angle.
2, anti-static ability
LED, long life, high resistance to static electricity, and therefore the price is high. The 700V can be used for LED lighting with more than LED.
Wavelength consistent LED, the same color, such as the requirements of the same color, the price is high. No LED color device manufacturers are difficult to produce pure color products.
White light into the warm color (color temperature 2700-4000K) and white (color temperature 5500-6000k), cool white (color temperature 7000K above) Europeans prefer warm white.
Red: band 600-680, 620630 of which are mainly used for stage lights, 690 close to infrared
Blue light: band 430-480, in which 460465 stage lights used more.
Green: band 500-580, in which 525530 stage lights used more.
4, leakage current
LED is a single direction of the light emitting body, if there is a reverse current, then known as leakage, leakage current LED, a short life, low prices.
5, luminous angle
Uses different LED its luminous angle is not the same. Special light angle, the price is higher.
Different quality is the key of life, life is decided by the light fades. A small decline, long service life, long service life, high price.
7, LED chip
LED emitter for the chip, different chips, the price difference is very big. Japan, the United States of the chip is more expensive, Taiwan and China local manufacturers LED chip prices lower than Japan, the United states.
8, chip size
The size of the chip to side said, chip size is generally: 28-45MIL, the quality of chip LED chips is better than small. The price is proportional to the size of the chip.
General LED's colloidal silica gel, with anti UV and fire retardant LED price is more expensive, high quality outdoor LED lighting should be UV and fire.
Hailong Xing electronics as a high-tech enterprises in Shenzhen City, the company has the most advanced automatic solid crystal, wire, plastic injection, light color separation equipment and supporting performance superior detection equipment, won a number of independent patent of science and technology, master the latest packaging technology, using imported from the United States, Dow Corning optical silica gel, imported from the United States intematix phosphors, 99.99% pure gold wire welding.
The workshop of anti-static, dust-proof, strict control and guard. All staff and customers and related personnel to enter our production workshop, we must do a good job in the prevention of static electricity can enter, all of our equipment and machinery in the relevant personnel under the guidance of proper and ground.
There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
LED is the light emitting diode, which is a semiconductor solid light emitting device that converts electric energy into light energy. Its core is the PN junction. In addition to the forward conduction, reverse cut-off and breakdown characteristics of the general PN junction, it also has the light emitting characteristics under certain conditions. Its structure mainly includes the following parts: lead, bracket, encapsulation glue, bonding wire, LED chip, solid crystal glue and phosphor. The discoloration failure of LED lamp bead is closely related to its material, structure, packaging process and service conditions. The following will analyze the causes of its discoloration through specific cases.
LED lamp beads are also called light emitting diodes. It has a wide range of applications. Its luminous colors include red light, emerald green light, yellow green light, yellow light, purple light, blue light, white light and orange light. The above is monochromatic light. It can also be made into two or three colors.
The gold wire used to package LED lamp beads contains more than 99.99% gold. It is produced by drawing gold from this material. In addition to 99.99% gold, this gold also contains less than 1% other trace elements. One of the core components of LED lamp bead packaging is gold wire, which is the bridge connecting the luminous chip and the welding point, and plays a decisive role in the service life of LED lamp bead. So how to identify the purity of gold thread?
