How to configure the optical lens of the flashlight

Time:2020-09-03  来源:Dongguan Lianlong Optoelectronic Technology Co.Ltd

There are many types of flashlights depending on the environment in which they are used, so different types of flashlights need to be equipped with different LED lenses. How does the manufacturer configure the LED lens for the flashlight? The following analysis from several points.

Because different brands of high-power LEDs have different optical characteristics and light distribution curves, so the same flashlight lens is assigned to different brands of LEDs will have different effects, such as: the difference in the angle of light, the effect of the spot, etc. It is necessary to determine the matching method of different LEDs and LED lenses according to different applications. The specific prerequisites are: whether to choose a single lens one-to-one or a multi-lens lens module; the distance to be irradiated is different from the plan and the corresponding condensing angle is determined; the diameter or height of the flashlight lens is determined according to the different specifications of the flashlight ; According to different brands of LED light source to determine the corresponding flashlight lens.


       Generally, if the flashlight needs higher brightness under the same power (current), please use the LED light source with higher luminous flux value. Please choose CREE and lumileds for flashlights that need a smaller angle for concentrating, because the LED phosphors of these two brands are less and small, and the area of the point light source is small, and the use of small-angle concentrating or small-angle concentrating is higher. ; And some domestic LED light sources are not suitable for 5 degree condensing, because the area of point light source is larger, such as 5 degrees, the light utilization rate is less; this type of LED is more suitable for 15 degree condensing Light.

In short, the condensing effect of the flashlight has a lot to do with the use of high-power LED light sources of different brands. At the same time, the intensity and range of the flashlight are also related to the power planning, current size, LEDs with different LM values, and different parameter types. The selection of the LED lens is also very important. Some LED flashlights can also choose to use a reflector to condense the light; you can also use a reflector to communicate with the lens (modular type) for condensing.
