High-power LED beads selection should be analyzed from the following aspects, including LED brightness, anti-static ability, wavelength, leakage current and other 9 aspects.
Along with the development of modern society, people living standard rise, lighting light source also great changes have taken place, and now a new kind of LED light source form, because of its high brightness, low quantity of heat, long life, non-toxic and can be recycled, become people daily life of the most common lighting light source, and the stand or fall of LED lamps and lanterns and the LED lamp bead quality has the very big relations, a good LED lamp bead to make the LED lighting products in effect is better.
The selection of high-power LED beads and LED point light sources should be analyzed from the following nine aspects:
1. LED brightness
Prices vary depending on the brightness of leds.
Lamp cup: the general brightness is 60-70lm;
Bulb lamp: the general brightness is 80-90lm.
Note: 1W brightness of 60-110lm3w brightness up to 240lm5w-300w is integrated chip, with series/parallel packaging, mainly depends on how much current, voltage, a few series and a few.
1W red light brightness is generally 30-40lm; 1W green brightness is generally 60-80lm; 1W yellow brightness is generally 30-50lm;
1W blue light brightness is generally 20-30lm;
LED lens: PMMA, PC, optical glass, silica gel (soft silica gel, hard silica gel) and other materials are generally used for primary lens. The larger the Angle, the more efficient the light will be.
Shenzhen XinGe photoelectric lighting co., LTD., over the years has always been professional, concentrate on with independent intellectual property rights LED visible light, point light source, line light, wash wall lamp, project-light lamp, and other products of the production and application, mainly provides the design of landscape architecture and advertising lighting project, project budget, product, on-site guidance, after-sales service and other comprehensive business.
2. Anti-static ability
Strong anti – static LED, long life, and therefore high price. LED is usually more than 700V antistatic can be used for LED lighting.
LED with the same wavelength, the color is the same, if the color is the same, the price is high. It is difficult for manufacturers to produce pure color products without LED spectrocolorimeter.
White light is divided into warm color (color temperature 2700-4000k), positive white (color temperature 5500-6000k), and cold white (color temperature above 7000K). Europeans prefer warm white
Red light: band 600-680, of which 620,630 is mainly used for stage lights, 690 near infrared
Blue light: band 430-480, in which 460,465 stage lights are used more.
Green light: band 500-580, of which 525,530 are used for stage lights.
4. Leakage current
LED is a unidirectional conductive luminous body, if there is a reverse current, it is called leakage, leakage current large LED, short life, low price.
5. Luminous Angle
Leds used for different purposes have different luminous angles. Special luminous Angle, higher price.
The key of different quality is life, life is decided by light decay. Light decline small, long life, long life, high price.
7. LED chip
LED luminous body is chip, different chip, price difference is very big. Chips from Japan and the United States are more expensive, and LED chips from Taiwanese and Chinese manufacturers are cheaper than those from Japan and the United States.
8. Chip size
Expressed as a side length, the size of the chip size is commonly: 38-45 m Ω, large LED chip quality is better than that of the small chip. The price is proportional to the size of the chip.
The colloid of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fireproof agent is more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
