What Is the Receiving Head of the Infrared LED Lamp Bead?

What is the LED infrared receiving head for infrared LED lamp beads? Infrared receiving head, referred to as the receiving head for short, can also be called infrared receiver, infrared receiving tube, infrared receiving module, remote control receiving head, or infrared“Wire”Words, such as infrared receiving head. The English name of infrared receiving head is Infrared Receiver Module, referred to as IRM for short. Appearance: According to the appearance, it can be divided into two categories: nose bridge type, ball type (dot type). The bridge of the nose can be subdivided into large nose bridge, standard nose bridge, small nose bridge. In addition, there are other special ones, such as ultra -thin, mini type, straw hat type, patch type, with line receiving head. Category: In addition to classification from the appearance, it can also be classified according to the packaging method, which is more accurate. There are two major categories of receiving heads that can be bought on the market: pressure models and glue type. Generally speaking, the bridge of the nose is attributed to glue type, and the ball type is attributed to the pressure model. From the perspective of two packaging processes, the pressure model equipment is large, and the price of the rubber cakes is more expensive, so the overall price is more expensive. Of course, it must be strong in resistance to light. Plug -type equipment is small. Nowadays, most of the domestic factories are irrigated products. The strengths are cheap prices. Of course, there are also false pressure models. The use of glue method is used to make the ball shape. The shape of the embodiment is similar to the molding method, but the function must not be performed well. Sometimes it is divided into iron vests outside the head, so you can divide the receiving head and divide the dividend and seal and the iron shell. The benefits of multiple iron shells are more oversized shielding. The effect is relatively stable. Of course, if the product design is OK, the receiving distance of the plastic seal is slightly farther in the same piece. Of course, there will be some differences in the price of not with iron shells, so if you choose the receiving header, you should be determined according to the design according to the design. Under normal circumstances, use plastic seal on toy products, and use more iron shells on home appliance products. Composition: The first part of the receiving head is mostly composed of optical diode (PD), chip (IC), bracket, colloid (pigment, epoxy resin). The primary function of PD is to receive light signals. There are large, medium, and small, the larger the scale. In the same case of other raw materials, the farther the receiving distance, the larger the receiving point. IC is a disposal element for LED infrared receiving heads. It is composed of silicon crystals and circuits. It is a highly integrated equipment, the primary functions include filtering, plastic surgery, decoding, amplification and other functions. Anti -light disturbance talents, anti -power disturbances, dry power, receiving distance, decoding talent, product stability and other elements. The bracket is the pin part of the receiving head, which is connected to the IC function foot, and the fixed chip is equivalent. The colloid is a black matter mixed with pigment and epoxy resin. The epoxy resin contains the effect of PD and IC. The pigment has a great effect on the resistance of the product. , But the filtering function is better, which can be filtered out of the visible light below 850nm. Another type of compression model packaging is a rubber cake. This kind of anti -light disturbance is best. Therefore, the same receiving head from the appearance, because the composition is different, the price of the same appearance in the market is ranging from 0.4 1 yuan, the price ranges from 0.4 1 yuan. Because IC is the biggest element that affects the price, when choosing the product, pay attention to the price -performance ratio. You must not just look at the price and forget the quality.
