The emitting angle of SMD LED light emitting diode is an important parameter, which determines the propagation range and lighting effect of light. Different application scenarios require different emitting angles, so it is very important to understand the emitting angle selection of SMD LED light emitting diode.
Generally speaking, the emitting angles of SMD LED light emitting diode can be divided into the following categories:
1. Narrow-angle emitting: The emitting angle is usually between 15° and 30°. The light emitted by SMD LED light emitting diodes with this emitting angle is more concentrated, which is suitable for occasions that require long-distance lighting or need to emphasize specific areas, such as flashlights, spotlights, etc.
2. Medium-angle emitting: The emitting angle is between 45° and 60°. The light emitted by SMD LED light emitting diodes with this emitting angle is more uniform, which is suitable for general lighting occasions, such as indoor lighting, billboard lighting, etc.
3. Wide-angle emitting: The emitting angle is between 90° and 120°. The light emitted by this SMD LED light emitting diode with a luminous angle is very scattered, which is suitable for occasions that require large-area lighting or soft light, such as table lamps, wall lamps, etc.
In addition to the above common luminous angles, there are also some special luminous angles to choose from. For example, some SMD LED light emitting diodes can achieve 180° full-angle luminous. This kind of SMD LED light emitting diode with a luminous angle can be used in occasions that require all-round lighting, such as spherical lamps, decorative lamps, etc.
When choosing the luminous angle of SMD LED light emitting diode, you need to consider the following factors:
1. Application scenario: Different application scenarios require different luminous angles. For example, in occasions that require long-distance lighting, you should choose a narrow-angle SMD LED light emitting diode; in occasions that require large-area lighting, you should choose a wide-angle SMD LED light emitting diode.
2. Lighting effect: The luminous angle will affect the lighting effect. The light emitted by the narrow-angle SMD LED light emitting diode is more concentrated, which can produce a stronger light intensity; the light emitted by the wide-angle SMD LED light emitting diode is more dispersed, which can produce a soft lighting effect.
3. Installation position: The installation position will also affect the choice of the emitting angle. If the SMD LED light emitting diode is installed at a higher position, a wide-angle SMD LED light emitting diode should be selected to ensure that the light can cover a larger range; if the SMD LED light emitting diode is installed at a lower position, a narrow-angle SMD LED light emitting diode should be selected to avoid excessive dispersion of light.
In short, there are many options for the emitting angle of the SMD LED light emitting diode. When choosing, it is necessary to comprehensively consider factors such as application scenarios, lighting effects and installation locations to select the most suitable emitting angle.
