LED Bulb Buying Guide: How to choose a health G4 LED lights

In recent years, as people's awareness of healthy lighting, more and more people are concerned about health and buy LED lights. But the face of the market include a wide variety of LED lights, how to choose, how to choose has become a headache for many consumers. Today, small series from professor aspects you how to choose a healthy LED lamps provide a reference for the future purchase of LED lights.

 

1 see light beads

 

Lamp beads are the core components of LED lamps, different models, different quality lamp beads luminous efficiency, light emitting angles are different. Most lamps are now available in a single crystal lamp beads, which is only one crystal. Double crystal beads lamp performance is better than a single crystal lamp beads, beads life expectancy longer than single crystal lamps. Compare the following figure three light bulb, the bulb snow Wright has double-crystal lamp beads, so the same luminous flux smaller. The same luminous flux, the general use of double-crystal lamp beads lamp beads required amount significantly less than the number of single-crystal lamp beads, more conducive to optimizing the lamp body size;

 

As can be seen, the same power 5W, three male LED bulb, Foshan Lighting LED bulb, light body size significantly larger than the Wright products.

 

 

Therefore, in the purchase, you can consult the Purchasing Guide bulb lamp beads, try to choose double-crystal lamp beads, not only long life, and light-emitting efficiency, light-emitting angle is higher, and more extensive use of occasions.

 

2 Look brightness

 

When you purchase LED lights, many consumers mistakenly think that the higher the brightness, the light bulb, the better, in fact, this is a big misunderstanding purchase. Because the  3000K led light is too bright as midday glare of the sun, not only easy to damage the eyesight, but also affect the physical and mental health, in particular, it is likely to cause the child withdrawn, restlessness, irritability character. Therefore, in the choice of E12 LED 2W 100-130lm 3000K led  lighting, requires a combination of lighting conditions, 12V led refer to the product flux index, or observe the brightness of the light, try to choose adequate but not dazzling brightness lamps.

 

3 see color

 

Look CRI is to see objects in the light of the true color. High real objects are preferred. For example, the following comparison of the two images, the left picture is very real, the picture on the right is clearly a serious distortion.

 

 

We can hand-colored objects placed at the head of the light bulb to do some experiments, and from a more professional point of view can be used to purchase a color rendering index, a lamp color rendering index of 80 or more is better, the higher the color rendering index, light reduction of the object at the higher.

 

4 See dissipating material

 

Since the lamp lighting process will produce heat, light bulbs must have good heat dissipation. Heat lamp ceramic material best, followed by plastic clad aluminum, plastic again. G4 LED When you purchase, the best choice of bulb ceramic material, plastic material as far as possible without regard to reduce the probability of risk. The patented ceramic heat technology Wright bulb approach is the use of ceramic materials, aluminum heat sink combination, and effective contact with the bonding surface light source PCB area between the radiator close, which are conducive to heat conduction.

 

 

5 see light housing bubble

 

 

Bubble lamp shade lamp shell commonly known, this part of the material largely affect the lighting effects transmittance of light, glare, light and shadow. Currently available LED ball bubble shell generally PC 4W LED, two materials are mainly glass, wherein the light transmittance of the glass top, better light transmission properties, uniform light-emitting shape better, can reduce glare, spot the situation, but the disadvantage It is relatively brittle.

 

Most other bulbs use PC material, the light transmittance weaker, while the PC housing poor long-term use but also easy to aging yellow.
