Which is better? In terms of power and price
I think this brother is not very clear about leds; In fact, the lamp contains the way of the patch Led lamp bead classification 1. Straight insert small power specifications are as follows: straw hat/helmet, round head, concave, ellipse, tombstone type (2 * 3 * 4) bullet, flat head, type (3/5 / flat bread) piranha, etc. 2. SMD patches are usually divided into (3020/3528/5050, these are positive luminescence) / 1016/1024, and these are the lateral luminescent sources. 3. Large power leds are not classified into the patch series, their power and current usage are different, and the photoelectric parameters are very different. Single single high power LED light source, such as no heat dissipation base (generally for hexagonal aluminum), its appearance and the average patch without too big gap, high power LED light source is circular, encapsulation mode basic and SMD patch is the same, but with SMD patch in the conditions of use/environment/effect has essential difference. Photosynthetic efficiency as to what you say, he is equal to the luminous flux/power is the power points, as we have 3014 (0.1 W), 3528 (0.06 W), 2835 (0.5 W)... The flux is also the customer's requirement, we have 5 to 60 lm here, of course the price is different. Hope is useful to you
The leds used in T8 are not the same as leds, and the effect is that leds are good and have a long life. The power aspect can be determined according to the need, the price aspect LED stick lamp is higher than the T8 lamp of LED light bead.
Light source (3528, 3014, 2835 light bead), baseboard (aluminum plate, glass fiber board), aluminum profile, PC cover, power supply (isolation/uninsulated constant current power), block head. The light effect is connected with the power and flux of the light bulb, and I wonder what you mean by this LED lamp structure.
The structure of LED fluorescent tube consists of: lamp shell, plug, lamp ball, circuit board, power supply.
