Because the shape of the led bulb is round, it is also called the led bulb. It is one of our common LED lamps, and now it is mainly white LED single lamp. Although the structure is simple, because it is a point light source, it has a wide range of applications, and it will achieve better development in the field of room lighting design and development. According to the shape of LED bulbs, they are generally divided into four categories, spherical bulbs, pointed bulbs, cup-shaped bulbs and corn bulbs.
1. Spherical LED bulb: single-sided light, the lower part is a plastic shell or an aluminum shell, and some spherical luminous arcs are different, the shell is plastic-clad aluminum or aluminum; the Langte LED bulb uses the existing interface method, That is, the screw port E26E27E14, etc., the socket type B22, etc., imitate the shape of the incandescent bulb in order to conform to people's usage habits. Some also use led filaments, and the shell is glass. Simulate early incandescent bulbs. But the light efficiency is greater than that of ordinary incandescent bulbs. Based on the unidirectional light-emitting principle of LEDs, we have made changes to the structure of the lamp so that the light distribution curve of the LED bulb is basically the same as the point light source of the incandescent lamp.
2. Pointed led bulb: single-sided light-emitting, similar to a spherical shape, that is, the shape is pointed; chrome-plated three-sided light-emitting, there is an aluminum substrate led light board inside. This is a high-end product with good luminescence efficiency, but there is no luminous point on the top; the candle type is a pointed bulb with a base with a lamp cap, which is basically the same as a pointed bulb.
3. Lamp cup-shaped led bulb: Early lamp cup + aluminum substrate led light source, which generates a lot of heat. There is a tendency to be eliminated gradually. Divided into car aluminum and cast aluminum.
4. LED corn lamp: ring + top light, commonly known as corn bubble, because the shape of the led lamp bead structure is very similar to corn; the three-pronged shape can also be regarded as the light-emitting method of corn bubble, but it has a more scientific structure than corn bubble, so It is currently more popular.
The advantages of led bulbs are: energy saving-the energy consumption of Langte white LED bulbs is only 1/10 of that of incandescent lamps and 1/4 of that of energy-saving lamps; the life span can reach more than 100,000 hours, which can be described as once and for all for ordinary household lighting; LED bulbs belong to Type of cold light source. It is usually packaged in color box or white box, which is convenient for transportation and installation. It can be installed in any miniature and enclosed occasions without fear of vibration and no need to consider heat dissipation. The design of indoor lamps and lanterns is based on led bulb design as the mainstream, and at the same time fully reflects energy saving, health, The development trend of art and humanization has become the dominant lighting culture in the room, and its use is relatively large, due to its small size, and the installation method is particularly flexible. Can replace traditional light bulbs.
The structure of led bulb has three main parts. Housing, power supply and light source. The rule is that if the power is increased, the enclosure will become larger. The power supply is built-in and generally has a relatively small size. The capacitor has a long life to resist heat. The LED lamp beads usually used in the light source generally use two common lamp beads, 2835 or 5730, which is cost-effective. High-power LED bulbs are also made with a single 1-3w LED lamp bead.
For the use of led bulbs, the general input voltage is 220v, and there are also wide-voltage 85-265v using a constant current source, which is not interfered by the power grid. There are also low-voltage methods, such as 24v and 36vled bulbs. Before using, confirm the voltage. Since the interface is universal, you only need to replace it directly. Be sure to explain the voltage type to the manufacturer when purchasing. led fluorescent tube continued
