What does the LED bulb patch mean?
According to different applications, different size, cooling scheme and luminous effect of.LED packaging forms. At present, according to the classification of LED package are mainly Lamp-LED, TOP-LED, Side-LED, SMD-LED, High-Power-LED, Flip Chip-LED Lamp-LED (vertical LED) emerged in the early Lamp-LED is in line LED, it adopts the form of sealing packaging. The potting process is the first injection of liquid epoxy resin in LED molding cavity, and then insert the pressure LED bracket welding, in the oven make epoxy resin after curing, the LED from the cavity from the molding. Due to the relatively simple fabrication process, low cost, have a higher market share. (SMD-LED surface mount LED) patch LED is pasted on the surface of a wiring board, suitable for SMT processing, can be reflow, a good solution to the brightness, perspective, smoothness, consistency, reliability and other issues, the The lighter PCB plate and a reflecting layer material, improved to remove the carbon steel pin dip LED heavier, the display of epoxy resin less reflective layer needs to fill, to reduce the size, reduce the weight. In this way, the surface mount LED can easily reduce the weight of the final product in half, make the application more perfect.
The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.
Performance of LED patch lamp:1, micro power consumption: LED lamp, 2W brightness is equivalent to 40W incandescent brightness, 3.6W brightness is equivalent, 60W incandescent brightness, brightness in the middle stronger.2 、 voltage adaptation range: nominal 220V lamp.3 、 the light distribution technology expands the LED point light source to the surface light source, increases the luminous surface, eliminates the glare, enhances the visual effect and eliminates the visual fatigue;4 、 lens and lampshade integrated design. At the same time, the lens has the functions of light gathering and protection, thereby avoiding repeated waste of light and making the product more concise and beautiful;5 、 high-power LED flat cluster package and radiator and lamp holder integrated design. The LED heat dissipation requirement and the service life are fully guaranteed, and the design of the LED lamp structure and the shape are completely satisfied, and the LED lamp has the distinctive characteristics of the lamp;6, Aluminum Alloy lamp body and the overall molding process, to ensure a good cooling effect, reducing the effective use of LED in the process of decay.7 、 no strobe. The pure DC work eliminates the visual fatigue caused by the strobe of the traditional light source; and the environment is green. No lead, mercury and other polluting elements, no pollution to the environment;8, impact resistance, resistance to leilijiang, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, no fragmentation of traditional lamp, no harm to human body, no radiation.
In order to obtain high power LED light source, high brightness, the manufacturers to power direction in LED chip and package design. At present, the LED package can withstand W power has emerged. For example, Norlux series of high-power LED packaging structure for the hexagonal aluminum plate as base (the conductive) multi chip combination. The base diameter of 31.75mm, light emitting area is located in the central part, a diameter of about mm (0.375 * 25.4), can accommodate 40 LED tube core, at the same time as the aluminum heat sink. This package uses conventional tube core combination of high density packaging, high luminous efficiency, low thermal resistance, high in light output power flow under high electric. Is a kind of promising LED solid state light source.
The LED patch (SMD) is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
