Is a flashlight or a floodlight flashlight used? What's the difference

If not professional flashlight enthusiasts, in the purchase of flashlight often more confused, do not know what to buy more suitable, such as pan light flashlight and spotlight, many people do not know what is the difference between the two.

Floodlight
The center spot of the floodlight flashlight is slightly concentrated, and the diffuse light of the flood area is large. The angle of illumination is large, the range of illumination is wide, and the light is soft and dazzling.
A floodlight flashlight produces a highly diffuse, non directional light rather than a clear outline of a light beam, which produces a soft and transparent shadow. When the object is illuminated, the speed of the lighting is much slower than that of a spotlight, or even a very slow light, which looks like a non shadow. The light source.
The spot shows: the central spot is strong, and the light area is weak. There is a smooth transition between the floodlight region and the central spot, and the floodlight does not refer to the completely scattered light. The floodlight also has a strong central spot. It is not a light spot like a street lamp or an indoor light. It is a floodlight relative to the light.
Advantages: the central light spot is strong, the light distribution is uniform, the visible angle is large, the range of radiation is wide, it is suitable for the middle and far distance radiation, the light covers the object clearly and without the eye.
Disadvantages: the irradiation distance is not far enough, the light is slightly dispersed.
Application areas: outdoor activities, camping, hiking, night riding, fishing, mountaineering, household, search and rescue and so on need gentle and large area lighting activities. In the dark fields of jungle or deserted deserts, we are more eager to understand the surrounding environment in the dark, and the range of flashlight can also meet the demand.


Spotlight flashlight
Spotlight flashlight refers to the use of condensing lenses or mirrors to gather light. The focus of the concentrator flashlight is bright, the brightness outside the center spot is low, and the concentrating flashlight projects a directional, clear boundary beam to illuminate a specific area. The center spot is small and strong, and the long-range effect is very good. Usually the mirror (smooth surface) reflector cup is matched with the small core LED. The caliber and depth (height) of the reflective cup directly affect the degree of concentration. The curve design of the reflector determines the position of the spot and the shape of the spot.
The spot shows: the center spot is small and round, and the light area is weak. There is a clear dividing line between the flood area and the central spot. There are several ring rings (halo) at the periphery of the spot. Excellent spot, with a regular round center, no black spots and clear boundaries.
Advantages: the central light is bright, the light is concentrated, the long-range effect is good, and it is suitable for long distance exposure.
Disadvantages: there is less light in the vicinity, the light can not diffuse evenly, and the range of illumination is small.
Applications: outdoor activities such as speed of light, hunting, high-speed night riding, and special outdoor operations.
Spotlight (with both spotlight and floodlight)
The focusing hand power is called the zoom hand power. The principle is to realize the spotlight and floodlight by adjusting the distance between the convex lens and the bulb. The focus of the focus is mainly rotary focusing and telescopic focusing, because both the light and the pan light are taken into account at the same time. It can be widely used in indoor and outdoor, such as hiking, camping, night riding, household, mountain climbing, night fishing and so on.
