Inertial thinking of stupid: high-power fire emergency lights behind the truth

Takeaway: a while ago, a friend who work in the fire emergency light sales very upset to tell me, now of the market too contrived, error to the consumer consumption idea, lead to many customers consulting the first question is asked whether the power of fire emergency lights, appears to be cognitive customer market still stays in the past with fluorescent lamp as light source of the fire emergency light era, that the inertia fool: power is the truth behind the fire emergency light?

Industry professional people all know that the fluorescent light source of fire emergency light is uneven due to technology, to meet the national standard brightness of the fire emergency light of credit usually around 3 w 5 w power, and high technical level, may be able to use a few main electrical can meet the national standard brightness, which have the effect of energy saving, so the price of this kind of fire emergency lamps and lanterns is also higher than the average.
But now seems to be opposite the market rules, high power on behalf of the high price.It seems that many consumers feel powerful fire emergency light is good, price is high also is taken for granted, and a lot of fire emergency light manufacturers have also marked on their own lamps and lanterns 3 w, 4 w, 5 w, and even higher wattage, to meet the demand of the customer's consumption concept, and these so-called power fire emergency light virtual target parameters are undoubtedly manufacturer.
If according to the national launch of new gb standard now fire emergency lights, as long as it is using the LED as light source, the actual power consumption power is impossible also as before as the fluorescent lamp as light source of the fire emergency light.In about 1 w is normal.
Here it is necessary for knowledge about the brightness and energy saving lamps and lanterns explanation.Why use LED more energy efficient, because, the same brightness, 1 w LED light source than 3-5 w fluorescent lamp is higher the brightness of the light source.As a result, the brightness of the high and low with no direct relationship between the power wattage, but related to photosynthetic efficiency, luminous efficacy (LM), the greater the lumens value of the higher brightness.Terms, before 3-5 w fluorescent lamp light source of emergency lighting is 30-50 lm, 1 w LED light source of emergency lighting is now more than 50 lm, that is to say, now with 1 w LED as light source, fire emergency light brightness can be greater than 50 lm, and 3-5 w fluorescent light than before the fire emergency light and bright, also because of this, use LED as light source, fire emergency light electricity power is smaller, but the brightness is more bright, more than 50 lm above, to conform to the requirements of the new national standard of fire, have the effect of energy conservation and environmental protection.
Why is now on the market a lot with the parameters of the LED light source, fire emergency lights on the 3-5 w, give you a false cognition is 3-5 w is the mainstream?If you have to pay attention to their products will find the details of the above, they both 3 w and 5 w emergency lights are said 50 lm, this mistake is too obvious, use LED as light source but the energy consumption is the same as previous fluorescent lamp, and emergency lights are 50 lm, does that mean the circuit board of this product is very power, there is less than the requirements of energy conservation and environmental protection technology.Or exaggerate qi, making consumers pay for the so-called high power.Really good fire emergency light should be the emergency lights, the greater the emergency and the longer the higher the price only.Therefore, don't be deceived by one-sided so-called high power.
Finally, give you a suggestion, when selecting a fire emergency light should be focused on three parameters: the main electrical power, emergency lighting and emergency response time, the smaller the smaller the main electrical power consumption, can have energy saving effect, in accordance with the standards of this, I suggest you choose the main power for 1 w, emergency light efficiency than 50 lm (new gb standard) and emergency response time is more than 90 min fire emergency light.As far as I know, the current domestic fire emergency light four brands do best min-hwa, art light fire, rausch and leishi lighting, guaranteed in terms of quality, you can reference.In the end I have a small wish: I hope most of the domestic enterprises can build an industry standard for the market credit system, make consumers can buy high quality products.
