Lighting electrical safety certification service acceptance process, often encounter the floodlight lamps having similar fixed, often because of the suitability of the lamp according to the standard of security authentication and tangled, below on how to define, identify Floodlights Carding.
1 definition
Floodlighting: floodlighting floodlighting
Illumination that is projected onto the entire surface or the illumination of the object is much larger than the illumination of its surroundings.
Note: The difference between the illumination and the surrounding environment can be achieved by changing the color.
Floodlights: floodltglit
Used as a luminaire for floodlighting.
Note: Floodlights can be used outdoors or indoors, or both.
2 features
2.1 The light source does not highlight the light exit surface of the lamp housing
The beam angle of the floodlighting fixture is small, between 10° and 180°, and most of the projected light is concentrated in the beam angle range, so that the illumination in the illumination range is much larger than the illumination of the surrounding environment. In terms of appearance, the light source of the floodlighting fixture does not protrude from the light exit surface of the lamp housing, and the light emitted by the floodlighting fixture is concentrated in half of the spherical space. It can also be identified by checking the light intensity distribution curves listed in the product manual.
2.2 The reflector has a larger diameter and a shallower depth.
Conventional light source luminaires are equipped with a reflector to reflect all of the light from the source to the projected range of light. Common reflectors for floodlights are smaller in size and shallower in size. LED floodlights mainly control the beam angle through optical prisms.
2.3 Asymmetrical light distribution reflector
In order to make the illumination within the illumination range relatively uniform, the reflectors of some light-emitting lamps are designed to be asymmetrically distributed, and the shape of the reflector is of course also asymmetrical.
Symmetrical floodlights (one side asymmetrical)
2.4 with angle adjustment device
In order to facilitate the adjustment of the light projection direction, the floodlighting fixture usually has an angle adjusting device, which can adjust the angle of the light exiting port of the light emitting lamp to 1-2 degrees of freedom, and can clamp; fix the projection direction of the light emitting lamp.
2.5 fixed bracket is more rigid
The fixed bracket of the floodlighting fixture has a strong rigidity to accommodate the mechanical strength of the floodlighting fixture to withstand wind pressure when installed outdoors at a cantilever height.
2.6 enclosure protection class IP54
The outdoor light-emitting luminaire has a degree of protection of at least IP54, and the sealed luminaire housing prevents rain and snow from invading and dust accumulation.
2.7 using tempered protective glass or protective net cover
The illuminating surface of the light-emitting luminaire is made of tempered protective glass. Once broken, it can be broken into many small glass granules to prevent people from falling and falling into the sky. If the tempered protective glass does not meet the requirements, a protective net cover that prevents large pieces of broken glass from falling can also be used.
2.8 Additional protective measures
There are additional protective measures to prevent these components from falling in the event of a failure of the fixture under normal conditions. Additional protective measures can be: increase the number of fixing bolts, the attached wire rope, etc. at the same point.
2.9 have anti-loose measures
The connecting parts and fasteners on the luminaire shall be protected against loosening, such as spring washers, to prevent the mechanical connection of the luminaire from loosening due to vibration.
2.10 The risk of mechanical damage to high-power floodlights is even greater
Floodlights that use high-power electric light sources are often installed at high altitudes, used for long-range projection, large-scale lighting, and the risk of mechanical damage to high-power floodlights is higher.
3 judgment
3.1 Luminaires that are basically consistent with the characteristics of the above-mentioned floodlighting fixtures shall be certified according to GB7000.7 "Safety Requirements for Floodlighting Fixtures" for CQC Marking.
3.2 There are some (several) features that are consistent with the characteristics of the above-mentioned floodlighting fixtures, and some fixtures that are not completely consistent with the floodlighting fixtures should be evaluated according to GB7000.7 or GB7000.5, if the company insists that such lamps should be in accordance with GB7000. 201 "Lamps Part 2-1: Special Requirements Fixed General Luminaires" requires 3C certification. In order to avoid possible safety risks, the company must declare in the product manual: "The lamps are in accordance with GB7000.201" Part 2-1: Special requirements for fixed general-purpose lamps. Standard requirements for design and production, not tested according to GB7000.7 "Safety Requirements for Flood Lights" or GB7000.S "Safety Requirements for Roads and Street Lighting" There is no additional protective measures to prevent the lamp from falling and falling, and the windproof structure of the lamp has been evaluated. It cannot be used as a floodlight or tunnel light fixture."
The above-mentioned examples of the light-emitting luminaires are for reference only, and it is not required that any of the light-emitting luminaires conforms to all the above features. As long as the luminaire features are basically consistent with the characteristics of the light-emitting luminaires, they can be installed at high altitudes and may be subjected to wind pressure, vibration, etc. Luminaires that cause damage from high altitudes should meet the requirements of GB7000.7 "Safety Requirements for Floodlighting".
