LEP Sunlight Source

I. Characteristics of the Natural light series LEP light source

1.1. Characteristics of LEP spectrum

The Natural light series LEP light source is a continuous full-spectrum white light. The illuminated objects are displayed as clearly as under daytime sunlight. It has the characteristics of excellent color rendering, constant color temperature, extremely low light decay, no flicker, high brightness, strong fog penetration, energy saving and high efficiency.

The color temperature is 5000K-5500K, visible light accounts for 70%, invisible light accounts for 30%, red and blue light accounts for 68% of the visible light, and the spectrum wavelength ratio is very close to the spectrum of sunlight, see the table below:

1.2. Physical characteristics of LEP light source

LEP light sources all use high-purity quartz bulbs with extremely high light transmittance. They are resistant to high temperatures and can be used for a long time at 1100°C without bursting. Their safety performance is higher than that of ceramic glass bulbs.

With excellent natural heat dissipation performance, the integrated LEP light source (including amplifier, power supply and lamp holder) can keep the temperature as low as 58℃ (room temperature @ 32℃) during long-term operation.

The radiant heat of LEP light source during operation is significantly lower than that of LED.

1.3. Application advantages of the Natural Light Series LEP

The power density of the pure white light series LEP light source reaches above AM1.5 (≥1000W/m²), and the irradiation intensity reaches above 1.0Sun. The spectral matching, irradiation stability and irradiation uniformity with sunlight can reach the AAA level of the international standard for solar simulators.

The following is a list of the central illuminance of simulated sunlight at different distances: 114100Lux@15cm, 28000Lux@120cm (equivalent to direct sunlight at noon in summer)

2.2 Environmental requirements for LEP light sources

A) Work Environment

Temperature -25℃ to +45℃, humidity 5%-95%.

B) Storage environment temperature

Temperature -40℃ to +80℃, humidity 5%-95%.

2.3. Heat dissipation requirements of LEP light sources

A) Power supply cooling

If the LEP power supply is external, the power supply shell itself can meet the heat dissipation requirements. If the power supply is built-in, the heat dissipation must meet the requirement that the temperature rise is less than 35°C under a 25W heat source.

B) Power amplifier heat dissipation

The power amplifier (microwave solid-state source) must meet the requirement that the temperature rise is less than 35°C under an 80W heat source.

C) System cooling

When the ambient temperature is 30°C, the shell temperature of the entire LEP system must be kept below 70°C to meet safety regulations.
