LED bulbs and energy-saving lamp between a difference

The appearance of LED bulb lamp is spherical, which people have been accustomed to.

The internal light source is LED bulb. With all the advantages of LED lamps:

1, energy saving, environmental protection,

2, long service life,

3, no stroboscopic, green.

That is the LED bulbs and energy-saving lamp between a difference.

More energy-saving: LED lamp energy consumption is 1/4 of the energy-saving lamp, incandescent lamp 1/10

Long life: The life of LED lamp is as long as 50,000 hours, which is 3-5 times longer than that of the energy-saving lamp.

Healthier: Uniform light guide, no strobe, no glare, no ultraviolet and infrared rays.

More environmentally friendly: without harmful substances of the mercury lamp, it can be recycled to protect the green earth.

Full-color change: rich in color, can show vivid and delicate patterns and effects.

Easy installation: Simple installation, direct replacement of incandescent lamp, low maintenance cost.

How to choose and buy LED bulbs?


At present, LED bulbs lamps are widely used in household lighting, but people are not very clear about the choice of LED lamps from the technical level.

Below from the following technical aspects, tell you how to buy led bulbs lamps.


  1. LED with different luminous angle uses has a different luminous angle. Special light-emitting angle, the price is higher. If full diffuse angle, the price is higher.


  1. The key to different quality of life is life, which is determined by light decay. Low light decay, long life, long life, high price.


  1. The luminescent body of the chip LED is the chip. The price of different chip varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips in Taiwan and China are lower than those in Japan and the United States (CREE).


  1. The size of the wafer is expressed by the side length. The quality of large wafer LED is better than that of the small wafer. Price is proportional to wafer size.


  1. LED brightness (MCD) is different and the price is different. The LED used for LED bulbs lamp should conform to Class I standard of laser grade.


  1. LED with strong antistatic ability has a long life and high price. Generally, LED with an antistatic capacity greater than 700V can be used in LED.


  1. LED with the same wavelength and the same color. If the same color is required, the price will be high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.


  1. Leakage current LED is a single-conductor emitter. If there is reverse current, it is called leakage current. The LED with large leakage current has a short life and low price.


  1. The colloid of ordinary colloidal LED is an epoxy resin. The price of LED with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fire.

Each product will have different designs, different designs are suitable for different purposes.

The reliability design of LED lighting includes electrical and mechanical safety, health safety, gas safety, fire safety, environmental safety, safe use of time and other factors.


From the point of view of electrical safety, it should conform to relevant international and national standards.


Because LED is a new product, China’s national standards lag behind, but the country provides product qualification testing.


LED lighting with international safety certification (such as CE, UL, etc.) and national product quality certification is more expensive because these products are reliable in safety design.


Consumers should carefully identify the authenticity of certificates. There are not many manufacturers with international safety certificates and national product certificates.


What if the LED bulbs lamp is broken?


After switching off the light switch, there are one to three flickers, which is due to the incomplete power liberation in the power supply.


It is the power supply flickering rapidly, which is the quality of power supply problems, there are many specific reasons.


It is found that the scintillation, due to the lack of power supply margin and the rise of temperature, is related to the design of power supply and the structural design of lamps and lanterns.


Generally, the excessive heat in the power supply stimulates the overheating protection function of the power supply itself.

The power supply has a protective device.

When the excessive heat may cause adverse effects on the power supply and the lamp, the power supply will actively power off, let the lamb rest for a while, fully dissipate the heat, and then turn on later.


So this is the power supply overheating protection at work.

This should not be the case with larger enclosures or with ventilation and heat dissipation where they are used.
