  • High Quality Street Light Housing Wholesaler shares the difference between the luminous angle of the LED fluorescent lamp housing and the beam angle

    1. The luminous angle of the LED fluorescent lamp housing: The luminous angle is also called the power angle. Usually we use the half power angle, that is, the angle of 50% luminous intensity is recorded as 2 & 1/2. The light emitting angle of the diode is also its light scattering angle, which is mainly controlled by adding a scattering agent during the production of the diode. There are three main categories:
    2. High directivity. Generally, it is a pointed epoxy package, or a package with a metal reflective cavity, and no scattering agent is added. The luminous angle is 5 ° ~ 20 ° or less, and has high directivity. It can be used as a local illumination light source or combined with a light detector to form an automatic detection system.
    3. Standard type. Usually used as an indicator light, its light emitting angle is 20 ° ~ 45 °.
    4. Scattering type. This is an indicator light with a large viewing angle, a light emitting angle of 45 ° to 90 ° or greater, and a larger amount of scattering agent.
    5. Beam angle of LED fluorescent lamp shell: Beam angle refers to the angle between two directions where the light intensity is equal to 50% of the maximum light intensity on a plane perpendicular to the center line of the beam The beam angle reflected on the illuminated wall is the spot size and light intensity. If the same light source is used in reflectors with different angles, the larger the beam angle, the smaller the central light intensity and the larger the light spot. The same applies to the principle of indirect lighting. The smaller the beam angle, the greater the ambient light intensity and the worse the scattering effect.
