LED tube replace fluorescent lamp solution
First of all, take the 40w ordinary fluorescent lamp of Foshan Lighting as an example; its luminous efficiency is about 47 lumens/watt.
The LED tube (diffusion cover) is about 110 lumens/watt, and the transparent cover can be as high as 130 lumens/watt, and
The luminous efficiency of the LED white light chip is still improving, and the experimental chip has reached 150 lumens per watt or more, which is the highest in theory
The value can reach 450 lumens/watt. The light efficiency is still improving.
Secondly, traditional fluorescent lamps emit light in all directions (360°), and a large part of it is wasted on the back, which is actually used for lighting.
The total amount of light is only 60%~65%; the light-emitting angle of the general LED fluorescent tube is 120°~180°, which is basically effective light.
Calculated by this method. The luminous output of a 40-watt traditional lamp (plus 8W ballast) is: 47 lumens * 40 watts
*65% (effective luminescence) = 1222 lumens; according to this calculation, the luminous output of a 12-watt Langte LED tube is: 110 lumens
*12 watts (real consumption) = 1320 lumens; saving electricity costs: up to 75%
Furthermore, take the world-famous Philips fluorescent tube as an example; its luminous efficiency is 80lm/W, then its effective luminous flux is: 80*40*0.65=2080lm. According to this calculation, a 19-watt Langte LED tube emits light. The amount is: 110 lumens * 19 watts = 2090 lumens. Save electricity bills: up to 48%
In summary, the luminous efficiency of Benwei's high-efficiency 18W LED tube exceeds that of 40W traditional fluorescent tube, whether it is a common brand or a world-famous brand. Whether it is high demand or low demand. In terms of lighting, it is fully competent. Industry continues to lead
