The light bulb is very familiar to us. Ever since Edison invented the electric light, the light bulb has brought light to thousands of households through the conversion of electricity and light. It can be said to be an indispensable necessity of life. . With the continuous advancement of people's wisdom, many changes have taken place in the modeling process and uses of light bulbs. For example, LED light bulbs are now the most popular light bulbs on the market. Not only because of its innovation, but more importantly because its quality is standard enough and its use time is long enough. So how should we choose LED bulbs? Now let the editor provide you with a satisfactory answer!
1. Look at the lamp beads
Lamp beads are the core components of LED lamps. Lamps of different models and quality The luminous efficiency and luminous angle of beads are different. Most lamps on the market now are monocrystalline lamp beads, which means there is only one crystal. Dual crystal lamp beads are more efficient than single crystal lamp beads and have a longer lifespan than single crystal lamp beads. For the same luminous flux, the number of lamp beads required when using dual-crystal lamp beads is generally significantly less than that of single-crystal lamp beads, which is more conducive to optimizing the size of the lamp body.
2. Look at the brightness
When purchasing LED lights, many consumers mistakenly believe that the higher the brightness, the better the bulb. In fact, this is a big purchasing misunderstanding. Because excessively bright lights are like the dazzling sunlight at noon, they not only easily damage vision, but also affect physical and mental health, and are especially likely to cause children to be withdrawn, irritable, and irritable. Therefore, when selecting lamps, you need to consider the lighting environment, refer to the luminous flux index of the product, or pay attention to the brightness of the light, and try to choose lamps that are bright but not dazzling.
3. Look at the color rendering
To look at the color rendering index is to look at the trueness of the color of an object under light. You can do an experiment by putting the colored objects on hand under the light bulb. Generally, it is better for the color rendering index of lamps to be above 80. The higher the color rendering index, the higher the degree of restoration of the object under the light.
4. Look at the heat dissipation materials
Since the light bulb generates heat during lighting, the light bulb must have good heat dissipation performance. Ceramic is the best heat dissipation material for light bulbs, followed by plastic-coated aluminum, and then plastic. When purchasing, it is best to choose bulbs made of ceramic materials, and try not to consider bulbs made of plastic materials to reduce the probability of danger. Sherlite bulbs using patented ceramic heat dissipation technology combine ceramic materials and heat dissipation aluminum plates, and the effective contact area between the light source PCB and the fitting surface of the heat sink is close, which is conducive to the conduction of heat.
5. Look at the lamp bubble shell
The lamp bubble shell is commonly known as the lampshade of the light bulb. This part of the material affects the light transmittance, glare, and light and shadow lighting effects of the lamp to a great extent. Currently, the LED ball bubble shells on the market are generally made of PC and glass. Among them, glass has the highest light transmittance, better light transmittance, uniform light emission and better light shape, which can reduce glare and light spots. However, it has shortcomings It is relatively fragile.
With the popularity and development of LED light bulbs, many manufacturers have seized this opportunity and manufactured LED light bulbs in large quantities. Therefore, there are more and more brands and types of LED light bulbs on the market, so many households are I became confused and confused when it came to choosing light bulbs. But don’t worry, through today’s analysis and introduction by the editor, you must have some understanding of this matter, so go and choose your favorite light bulb! However, you still need to pay attention, you must buy light bulbs in a regular store When purchasing, don’t be deceived because of cheap prices.
