Supplementary advantage
The intrinsic characteristics of the LED determine its many advantages, such as:
First, small size
The LED is basically a small chip that is encapsulated in epoxy, so it is very small and very light.
Second, low power consumption
LED power consumption is quite low, DC drive, ultra-low power consumption (single tube 0.03-0.06 watts), electro-optical power conversion is close to 30%. In general, the working voltage of the LED is 2-3.6V, and the working current is 0.02-0.03A; that is to say, it consumes no more than 0.1W of electric energy, and the same lighting effect is nearly 80% more energy efficient than the conventional light source.
Third, long service life
Some people call the LED light source a long life light. It is a solid cold light source, epoxy resin package, and there is no loose part in the lamp body. There are no shortcomings such as filament light-emitting, heat deposition, light decay, etc. Under the proper current and voltage, the service life can reach 60,000 to 10 Ten thousand hours, more than 10 times longer than traditional light sources.
Fourth, high brightness, low heat
LEDs use cold-lighting technology and generate much less heat than ordinary lighting fixtures.
V. Environmental protection
LEDs are made of non-toxic materials, unlike mercury-containing fluorescent lamps that can cause contamination, and LEDs can be recycled. There is no ultraviolet and infrared rays in the spectrum, no heat, no radiation, small glare, cold light source, safe touch, and it is a typical green illumination source.
Six, sturdy and durable
The LEDs are completely encapsulated in epoxy and are stronger than bulbs and fluorescent tubes. There is no loose part in the lamp body, which makes the LED not easy to damage.
How to buy
1. Luminous flux. The LED output luminous flux (LM number) is different and the price is different. LEDs for LED luminaires shall comply with the laser class I standard.
2, anti-static ability. LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with a typical antistatic of more than 700V can be used for LED lighting .
3. Wavelength. Good consistency LED, the color is the same, if the required color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4. Leakage current. The LED is a unidirectional conductive illuminator. If there is a reverse current, it is called a leakage current, and the LED with a large leakage current has a short life and a low price.
5, the angle of illumination. LEDs with different uses have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.
6, the life is different. The key to quality is life, and life is determined by light decay. Low light decay, long life and high price.
7, the chip. The illuminants of LEDs are wafers, and the prices of different wafers vary widely. The chips in Japan and the United States are more expensive, and the prices of wafers in Taiwan and China are generally lower than those in Japan and the United States ( CREE ).
8, the size of the chip. The size of the wafer is expressed in terms of side length, and the quality of the large wafer LED is better than that of the small wafer. The price is proportional to the size of the wafer.
9, colloid. The colloid of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fire retardant is more expensive. The high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire. Each product will have different designs. Different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, and safe use time. From the perspective of electrical safety, it should comply with relevant international and national standards.
From the aspect of health, the price of products designed with non-toxic materials is high, especially for indoor LED lighting. Don't use cheap LED lighting with odor. Only a few LED manufacturers use non-toxic materials to produce. Directly with the nose, the smelly product is much cheaper than the odorless one. Toxins like lead, mercury, and cadmium require professional analysis. From the perspective of applicable environmental safety, there is a reliable dust-proof and moisture-proof design, and the price of LED products with fireproofing, ultraviolet protection and low-temperature cracking is high.
