[0007] 2. The device uses a flashlight as an indoor lighting source, and indirectly tests the optical performance of the flashlight by testing the illuminance on the working surface according to the lumen method. The test results are consistent with the existing national product standard GA883-2010 "Great Light Flashlights for Public Security Single Police Equipment" , DB35 / T1306-2012 "LED Flashlight", and QB / T2198-1996 "Flashlight" do not meet the requirements, and cannot be used as the basis for correct evaluation of product performance and quality;
[0008] 3. The smoke inlet and exhaust cannot be controlled, and it is difficult to form a stable concentration of smoke inside the test chamber, resulting in poor repeatability of the smoke penetration performance test of the lamp;
[0010] 5. The device adopts the test method of fixed optical path distance, which cannot test the performance of fire-fighting lamps under different optical path conditions;
[0011] 6. The structure of the device is complex and the operation steps are cumbersome

Embodiment
[0034] Use the above-mentioned portable fire lighting performance test device to test the performance of two types of wearable explosion-proof lighting. The steps are as follows:
[0035] Step 1: Open the door of the cabinet, install one of the wearable explosion-proof lighting lamps on the lamp holder; adjust the up and down position of the lamp holder on the vertical rod, so that the explosion-proof lighting and the illuminance meter are on the same optical axis Start the stepper motor, drive the screw to rotate, adjust the position of the base on the guide rail, so that the optical path (horizontal distance) between the explosion-proof lighting lamp and the illuminance meter is 1m;
[0036] Step 2: Close the smoke inlet valve, open the smoke exhaust valve and smoke exhaust fan, and close the smoke exhaust valve and smoke exhaust fan after running for 10 minutes; adjust the optical smoke density meter and illuminance meter to zero; turn on the explosion-proof lighting switch,...

Abstract
The invention discloses a performance testing device and method for a portable fire-fighting lighting lamp. The testing device has a box body with an optical darkroom inside, and a smoke exhaust pipe and a smoke inlet pipe are arranged on the box body. The pipe and the smoke inlet pipe are respectively equipped with a valve and a fan; the inside of the box is equipped with an optical smoke density meter, an illuminance meter and a lamp holder; the lamp holder of the lamp holder is installed on the upper part of the vertical pole, and the position can be moved up and down along the vertical When moving, the lower end of the vertical rod is fixedly connected to the base, and the base and the screw rod driven by the stepping motor form a nut screw transmission mechanism, which can slide on the guide rail. The device is simple in structure and easy to operate; the smoke concentration and optical path can be adjusted. The device can be used to quantitatively test the performance of portable fire lights.
Description
technical field [0001] The invention relates to a portable lighting device, in particular to a device and method for performance testing of portable fire-fighting lighting lamps with different light sources. Background technique [0002] In the process of firefighting and emergency rescue, adequate lighting at the workplace is very important for fire investigation and personnel search and rescue. Among them, portable lighting is a kind of lighting equipment widely used by firefighters, which can be worn on the helmet or hand-held. Due to the complex and harsh environment of fire extinguishing and emergency rescue, and there are currently a wide variety of such personal lighting fixtures with uneven performance, it is very important to test the working performance of portable lighting used by firefighters in harsh environments such as dense smoke and so on. Portable fire lights are of great significance. [0003] GB7000.1-2002 "General Safety Requirements and Tests for Lamp...
