Recognize the construction of the luminaire:
The headlights are the most important lighting fixtures. In the traffic regulations, the luminosity and illumination range of the headlights are required. The effect of the lighting directly affects the traffic safety of you and others. The headlights are mainly enclosed and replaceable. Enclosed means that the bulb and the lens and the lampshade are made in one piece, which facilitates mass production of the entire lamp. The square and round lights of most mini and commercial vehicles are closed. The headlights of the car are mostly irregular shapes, which is not conducive to making the closed type, so the light bulb is separated from the lamp cover and the lens. The trend now is that the more high-end cars, the more headlamps that can be replaced with light bulbs.
Auxiliary luminaires are much simpler in construction, mostly in the form of ordinary incandescent bulbs, plus colored plastic shades. In the past two years, some imported cars have used colored bulbs and transparent lampshades on the auxiliary lamps. This kind of lamps look sparkling and really look good, but the versatility of the bulbs is much worse.
Check the whole car lighting effect
The requirements for the headlights are simple: the luminosity is sufficient and the projection angle is appropriate. Light is the test item when the vehicle is over the line, but in daily use, as long as you feel good. The lighting effect of the headlights is mainly related to two factors: luminosity and angle. The car will bump and vibrate during driving, so the lamp will be loose and misplaced, which is the most common cause of the decline in lighting effect.
The angles of the headlights are adjustable. Most of them are in the front compartment, behind the headlights, and are adjusted by positioning screws. Some are adjusted outside the car or electrically adjusted in the car. Without the aid of the metering instrument, the car can be parked in a straight road to start the engine, but it must be remembered that it must be generated by the generator to maintain the normal operation of the headlights. After each fine adjustment of the angle, in the low beam, high beam Switch between and adjust to what you feel is good.
In terms of auxiliary lighting, the requirements for the width, brake and reversing lights are bright enough and no flashing. The blinking frequency of the turn signals should be between 60 and 120 times per minute, and the frequency of the front and rear lights should be the same. If the auxiliary light is not bright enough, you should first observe whether the lamp cover is aging and yellowing, or water vapor caused by rain leakage. The method of cleaning the lamp cover is very simple. Just remove the lamp cover and wipe the inside with a damp cloth. If you feel that the projection angle of the light is ok, but the lighting is still not good, then change the bulb. There are two kinds of bulbs for automobile headlights: incandescent lamps and halogen lamps. Among them, halogen lamps have higher power-on efficiency and longer life. Although the price is higher, they are gradually becoming mainstream. When purchasing a light bulb, pay attention to whether the power of the new light bulb and the original light bulb are exactly the same, because if the power is too large, it will burn immediately. If it is small, the brightness will be insufficient. Generally, the label indicating the power will be attached near the lamp.
Do it yourself
To remove the bulb, start from the back of the luminaire. First remove the plastic or rubber sleeve at the rear of the luminaire. The plastic sleeve is unscrewed. The rubber sleeve can be opened directly, and then the socket portion can be seen. Most of the bulbs are fixed by wire springs. When the wire springs are shaken left and right, they will be loosened. Then the lamp holders can be pulled out. At this time, the lamp power must be checked again. The halogen bulb is a cylindrical small glass tube. When taking a new bulb, remember not to touch the surface of the glass with your hands. Otherwise, the grease on the glass will cause the temperature to rise when the bulb is energized, causing the bulb to break. There are several positioning pins on the base of the bulb. Insert the new bulb into its original position, make sure that the bulb does not loosen, and then return the entire headlight to its original shape in the reverse order of disassembly. Once you are done, you can return to the driver's seat, turn on the headlight switch, and enjoy the results of your labor. The lamp for the auxiliary lamp is simpler and is usually removed from the rear of the lamp. Most signal light bulbs are attached to a base plate that can be easily removed with a screwdriver. If it is a rear light, first remove the trim panel of the luggage. The bulb of the auxiliary lamp is generally a bulb-type incandescent lamp, and the fixing method is a right-angle plug-in type commonly used in our home. As with the headlights, remember to replace the bulb with the same wattage.

Kitchen series are linear actuators that can be used in kitchenware to make it smart. With actuators, extractor hood can be hide, working cabinet can be adjustable to the suitable height, and wall cabinet can be up and down, etc. Some are tiny enough for limited space, some are long and strong enough (15,000N) for big load.
