What are the different types of chip light sources for led street lights? Chip light source. 1-Pin Insertion Type (DIP) This kind of LED lamp bead is a light-emitting diode with a simple structure, because there are two pin-like filaments under the lamp bead, which can be directly connected to the circuit board, so it is called a pin-inserted lamp bead. Good safety, stable performance, low-voltage light emission, low loss, high efficiency, long service life, and multi-color lighting.

Common shapes: This lamp bead can have different shapes, such as round, oval, square or even shaped. Although it seems that there is not much difference in shape and size, the cross-sections of different shapes of lamp beads are different. Luminous type: If you look carefully at different lamp beads, you will find that the number of pins of some lamp beads is different.

These pins allow the LEDs to produce different colors of light. Application fields: In the field of lighting, pin plug-in lamp beads are hardly used; they are generally used as lamps, indicator lights, display screens, etc. Low Power Surface Mount Type (SMD) This kind of lamp bead light source is to solder the light-emitting diodes on the surface of the circuit board instead of passing through the circuit board.

It is small in size, and some are even much smaller than pin-inserted lamp beads. Common models: There are many models of this lamp bead, the more commonly used ones are 2835 (PCT), 4014.3528.3014, etc. The first two digits of each model number represent the width x.xmm, and the last two digits represent the length x.xmm. For example, 2835 means a width of 2.8mm and a length of 3.5mm.

The surface of the lamp bead is coated with yellow fluorescent powder and emits white light. Application fields: This kind of low power surface mount lamp bead is widely used. Because of its small size, it can be used at will, and can be attached to various LED lights, and the quantity can be adjusted and changed according to needs.

High power surface mount type. The third type of lamp bead is also a surface mount, which is similar to a low-power meter in essence, but with high power. The volume is a bit larger; on the fine structure, there is an extra lens, which can better gather light.

Common types: There are also many types of high-power surface-mounted lamp beads: If the surface color of the lamp bead is yellow, it is generally low color temperature; if the surface color is green, it is generally high color temperature; if there is no transparent phosphor, it is generally colored light. Application fields: This kind of lamp bead is usually used after wearing a lens (to facilitate light gathering or dispersion), and is usually made into spotlights and spotlights. Integrated Package (COB) The other is the integrated packaging lamp bead, which packs many lamp bead chips on the same board, which is the same size as the diameter of a five-cent coin.

A common shape is usually round. Long and square, long integrated boards are often used as desk lamps. Second, replace the light source.

LED replacement is based on a wider light source above the lamp bead. First of all, the lamp beads of LED street lamps can be made into various bulbs, which can be matched with traditional power interfaces and can be replaced at will. Application fields: The obvious meaning is that it can replace halogen lamps or incandescent lamps (low power consumption, high light efficiency); it can also be used as bulbs for chandeliers, decorative lights, downlights, and professional lamps.

Common models: light strip The other is the light strip, which can be divided into hard light strips and soft light strips, which can replace T5 fluorescent lamps. Features: The light strip is soft and small in size. Dimmable.

Can be cut and connected at will; strong plasticity. Easy to make and contour. Application fields:LED light tubes can be seen in schools, offices, shopping malls and other places.
