[0043] Track signal lights are key devices in railways and urban rail transit, used to ensure the safe and orderly operation of trains. Light Emitting Diodes (LEDs) are used inside track signal lights. Track signal lights warn trains through different colors. Exemplarily, the signal colors include red, yellow, and green, etc., representing stop, attention or deceleration, and running at the specified speed respectively.

[0044] LED optical power refers to the total power of the light emitted by the LED, usually expressed in watts (W). The magnitude of the optical power directly affects the brightness and luminous effect of the LED.

[0045] The following are some key information and calculation methods regarding LED optical power:

[0046] Definition of optical power: LED optical power refers to the total power of the light emitted by the LED, usually expressed in watts (W).

[0047] Optical power measurement: In order to accurately measure the optical power of LEDs, professional optical power instruments such as optical power meters and spectrometers are required. Optical power meters are mainly used to measure the total power of light sources, while spectrometers can measure optical power within different wavelength ranges.

[0048] The relationship between light power and light efficiency: The power calculation formula of LED lamp is power (W) = luminous flux (lm) / light efficiency (lm / W), where light efficiency refers to the luminous flux that the LED lamp can generate per watt of electrical energy.

[0049] Calculation in practical applications: In practical applications, the power calculation formula is power (W) = voltage (V) × current (A).

[0050] Luminous efficiency: The luminous efficiency of LED can be calculated by the ratio of luminous flux and electrical power, that is, luminous efficiency (lm / W) = luminous flux (lm) / electrical power (W).

[0051] Luminous flux: Luminous flux refers to the total amount of light emitted by a light source, measured in lumens (lm). The luminous flux of LED lamps is usually given by the manufacturer in the product specifications.

[0052] Method for calculating luminous power:

[0053] Simple method: If you know the luminous flux and working time of the light source, you can calculate the luminous power by dividing the luminous flux by the working time. For example, if the luminous flux of a bulb is 800lm and the working time is 10 hours, its luminous power is 80 watts (800 / 10).

[0054] Integration method: For more complex light sources, the luminous power can be calculated by using integration. This method requires the use of a spectroradiometer to measure the radiant power of the light source, integrate it to calculate the total luminous flux, and then divide it by the working time to get the luminous power.

[0055] Photometer method: A photometer is an instrument that can directly measure the luminous flux emitted by a light source. If you have a photometer, you can place the photometer near the light source and read the value displayed by the photometer. This value is the luminous power of the light source.

The guide rail moving module 2 drives the ranging module 3 and the detection module 4 to move along the first direction X to simulate the light path of the track signal machine 5 to be tested at different distances (such as Figure 2 , Figure 3 positions A and B in). A ranging module 3 is arranged above the guide rail moving module 2. The ranging module 3 measures the distance between the track signal machine 5 to be tested and the detection module 4 in real time through the signal reflected by the reflection panel 7. The detection module 4 includes a light intensity detection unit 41 and a processing unit 42. The light intensity detection unit 41 receives the optical signal emitted by the track signal machine 5 to be tested and converts it into an electrical signal to achieve the photoelectric conversion function. The photoelectric conversion is carried out through formula (1),

[0058] P in =i s / S (1)

[0059] wherein, P in is the incident optical power, i s is the photocurrent, and S is the photosensitivity.

When the luminous flux Φ is constant, the illuminance E is inversely proportional to the projected area, that is, the light intensity P received by the probe is inversely proportional to the square of the distance L. As shown in formula (two).

[0063] P = a / L^2 (two)

[0064] wherein, P is the light intensity received by the probe, a is the light intensity coefficient, and L is the distance between the track signal machine to be measured and the detection module.
