Led lighting is a brand-new lighting products, it is a major category of lighting, is led (light emitting diode) as a light source lighting products. Generally, there are living rooms, study rooms, living rooms, bedrooms, kitchens, bathrooms, and hallways. Because of their different functions, the required light sources are also different. According to different room features, choose different lamps. Although the led lights are good, the time will naturally be bad. So, do you know how to repair led lighting ? In fact, there is no need to ask the professional teacher for maintenance without asking the reason. It is entirely possible to check where the problem lies first, and to become a home-owner. Here is the necessary skills to learn led lighting repair with me! Led lighting introduction Led lighting is a kind of lighting, it is led (light emitting diode) as a new light source lighting products. It has the characteristics of energy saving, health and long life, and has practicability and decorative features. According to the installation site, it can be divided into many types. Lighting is the eyes of the home. If there are no lamps in the family, it is like people have no eyes and families with no eyes can only live in the dark, so the position of the lamp in the family is crucial. Ordinary energy-saving lamps have occupied the mainstream of the market, and emerging LED lighting energy-saving lamps are favored by all businesses, but expensive led lighting is difficult to enter the homes of ordinary people. Led lighting performance 1, energy saving: led is a cold light source, rely on semiconductor light, ultra-low power (single tube 0.03 ~ 0.06 watts), 150 ~ 200 lumens / watt, light source life of 10,0000 hours, light decay 3% to 7%. Semiconductor lighting itself has no pollution to the environment. Compared with incandescent and fluorescent lamps, the efficiency of electricity saving can reach over 90%. At the same brightness, the power consumption is only 1/10 that of ordinary incandescent lamps and 1/2 of fluorescent lamps. 2, health: led is a green light source. DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong directionality; good dimming performance, no visual error when color temperature changes; cold light source has low calorific value (Below 60°C), it can be safely touched; these are not reachable by incandescent and fluorescent lamps. It can not only provide comfortable lighting space, but also can meet people's physiological health needs. It is a healthy light source that protects eyesight and protects the environment. 3, led lights small size, light weight, epoxy resin package, can withstand high-strength mechanical shock and vibration, not broken, the average life expectancy of 100,000 hours, lamp life of up to 5 to 10 years, can greatly reduce the maintenance of lamps Costs to avoid frequent light changes, can be described as "one and every time" Led lighting features 1, the practicality of led lighting Can guarantee the use of indoor lighting, ensure the use of light health, eye protection, protection of vision, light color no abnormal psychological or physiological reactions, lighting firm, flexible circuit switch. In a sense, the decorative nature of lamps is also practical. Otherwise, decorative issues will not be discussed. For example, the use of lamps to decorate the living room will allow people to relax while enjoying. This lighting effect reflects the actual value of decoration. 2, led lighting decorative The first is ornamental, the lamp material is beautiful, the shape is unique, the color is more novel and beautiful; the second is the coordination, the cloth lamp form has been carefully designed, coordinated with the room decoration, and the furniture furnishings, the lamp modeling material and the furniture body material consistency , Can reflect the owner's artistic conception; Third, highlight the personality, light source color according to people need to create a certain atmosphere, such as warm, calm, comfortable, quiet, peaceful and so on. Highlight the particularity of the owner's requirements for lighting, reflecting different personalities. Under the premise of guaranteeing the use of light, it gives a person an artistic enjoyment of beauty. This is the unity of practicality and decorativeness of lighting. In terms of each lighting element, there is emphasis on lighting, emphasis on decoration, and both. . When choosing, it is necessary to combine the characteristics of different people, and consider different applications and interior decoration requirements. Led lighting installation details First, pay attention to the arrangement of the external lines of various types of devices to prevent polarity from being installed incorrectly. The device must not be placed too close to the heating element and the operating conditions should not exceed its specified limits. Second, we must not install led in the case of pin deformation. Third, when the decision to install in the hole, calculate the size and tolerances of the holes on the face and circuit board to avoid excessive pressure on the bracket. Fourth, when installing led lighting, it is recommended to use guide sleeve positioning. Fifth, when installing led lighting, special attention should be paid to the fire line and the zero line. Sixth, since led lamps are powered by low voltage DC, if they have their own power supply, they can be installed directly. If there is no power supply, they need to connect to a power output port. Of course, the general led lighting has its own power supply, so it is installed directly like an ordinary luminaire, that is, it is particularly necessary to explain that the led lamp has its own power supply, so use the led lamp and put the traditional starter and rectifier. Taken away, these two are useless. Led lighting maintenance First of all need to understand the cause of the bad led lights and need to replace the parts, either the light source (ie lamp beads), or the power drive. According to the specific conditions of the light is not lit, find the reason: The performance of a few lights does not shine, then you can replace the lamp beads; Lamp beads are all off, because the power supply channel is resistive or capacitive or a linear constant current. Replace the power supply driver. Lamp beads twinkling, the same as the driving power is broken, replace it; Find the reason, you can replace it, the first step is to first cut off the power! Cut off the power! Cut off the power! (Important things say three times) The second step is to replace the power supply on the back of the led lamp. This will directly remove the converter and replace the driver of the same type directly. The third step is to replace the lamp beads, remove the lampshade, take out the lamp board, and replace it with a new one. The fourth step, if you encounter the led lamp is outside the lampshade gap or drop, first of all, you must cut off the lampshade in the case of cutting off the power, if the broken is powerful, you can go to the market to re-select the size of a suitable lampshade Replace it with the new one. For the lamp shade of the led ceiling lamp, if used properly, the life span of the use is very long. The existence of the lampshade is equivalent to adding a protective layer to the wick. The wick penetrates the lampshade and can effectively block the moist air and prevent ultraviolet rays. Editor's summary: In fact, compared to the replacement of white light bulbs, the actual steps are a little more complicated, but as long as you master the three major steps of determining the root cause, turning off the power, and replacing it, it is still very economical and labor-saving. In the home process, if you encounter other problems, you can also seek the help of professionals, try to solve it yourself, so that as time goes by, I believe that my friends will become a home essential small expert, all-powerful up to it!

Center Drill Bit is also known as Slocombe Drills, Centre Drills were originally designed to create the countersink required to locate a tailstock centre when turning between centres. They have a point angle of 60° to match the angle of a Tailstock Centre.

A Centre Drill can also be used to provide a start location for a drill when drilling down the centre of a bar held in a Lathe chuck. Centre Drills are short and rigid enough to mark the bar centre without wandering off if they are carefully offered up to a rotating work-piece.
