What types of bicycle lights are there?
Bicycles are divided into five types, namely headlights, taillights, reflective footlights, side lights and spoke lights.
Headlight: Headlight This is an essential lamp, which is the safety guarantee for riding at night. Put a lamp bracket on the front of the car, and then put the bicycle lights in it. You can buy the rechargeable LED lamp, which is convenient without changing batteries. Moreover, LEG consumes less power and can be used for a long time. There is also a front reflector lamp, which can effectively let the opposite side observe its own light when coming from the opposite side, which is very important. Moreover, under the irradiation of the headlights, the reflecting distance of the reflector lamp is farther than that of the headlight.
Tail light: This light is placed under the rear frame, so that the rear car can find itself at the first time. With the switch device of the car light, it can be turned off in the road section with good lighting.
Pedal light: This light is installed on both sides of the two pedals. No matter which direction there is a car, it can well reflect the light. You can also see a light swinging up and down when the front car or the rear car does not turn on the light.
Side lights: The function is similar to that of foot lights, which emit light beside the car and have switch devices.
Spoke lamp: the spoke lamp is installed on the spokes of the rear wheel, and has a switch device, which can emit light in various ways and on both sides of the car; Spokes reflect light, how can I mix them on the spokes of the rear wheel to reflect light on the left and right headlights and make a reminder? The front wheel spoke lamp, with a switch device, will roll with the wheel to form a round lamp.
Choose the precautions suitable for bicycle lights.
What are lumen, lux and beam angle?
Lumen: the luminous flux emitted by a uniform point light source equal to one candle in a unit solid angle, and the lumen number on the bicycle lamp indicates the total amount of emitted light.
Lux: When the luminous flux of an object uniformly illuminated by light is 1 luminous flux per square meter, its illuminance is 1 Lux. Therefore, assuming that the lumen number of light remains constant, the larger the surface area, the smaller the illuminance.
Beam angle: The beam angle tells you the distance that light travels from the original light source. The focus of the small concentrated light is directly in front, while the wider light beam will spread outward, thus producing a beam of what is usually called "light".
How much lumen does it take to ride a flashlight at night?
At present, there are 200-2000 lumens of lights on the market. From the point of view of the brightness of bicycle lights, 400-800 lumens can be selected for normal road riding, and 1000-2000 lumens is more appropriate for mountain cross-country riding according to the light conditions. If it is a mountain race, it is recommended to choose higher brightness lights.
How to choose the right bicycle lights?
1. First of all, choose the one with a large irradiation range, the light is soft and not dazzling, and the ground can be seen comfortably and clearly. It is not required to shine far, and the low beam irradiation range should be wide.
2. In the light irradiation area, it is best not to have small spots one by one to avoid misjudgment caused by dazzle, while the light should be soft at the connection between the irradiation area and the dark outside; Where the light can't be found, there can't be other light, otherwise it will make the rider on the opposite side feel dazzling, which is not conducive to his own safety.
3. It is best to choose a rechargeable LEG lamp with low power consumption.
4. Choose the anti-seismic and waterproof functions. If the anti-seismic performance is not good, it is easy to cause danger if the gear jumps suddenly. Without waterproof function, the rain lamp will be dangerous under special circumstances.
