The special lamp for the lamp tube classroom led lamp tube led lighting fixture is a lighting product that uses light-emitting diodes as the light source, it can emit light directly, unlike ordinary light bulbs, which must be powered by a power source. Therefore, it has higher energy-saving efficiency than ordinary electric light sources. There are several types of led lights currently on the market:

1. Low-voltage DC power supply type This type of led lighting uses a low-voltage DC power supply voltage of 12v-24v;

2. High voltage DC power supply type and AC power supply type The difference between high voltage and low voltage is: under the same working voltage (usually 24 volts), the current of the AC circuit is greater than the current of the high-voltage circuit;

3. Single-ended output type and double-ended output type The advantage of single-ended is that the structure is relatively simple; the disadvantage is that because only one electrode is connected to the illuminated object, it cannot provide higher brightness at the same time. The advantage of double-terminal output is that it can provide higher brightness and larger power factor; the disadvantage is that the structure is more complicated, the cost is higher, and the maintenance is more difficult.

4. Hybrid There are both single-ended and double-ended chips in the same package. The advantages of this structure are low cost, long life (usually up to 100,000 hours), and high reliability (not easy to damage), but the drive circuit is more complex and costly.

5. High power and high power density High power and high power density are two different design methods realized under the same heat dissipation conditions.

6. Low heat design scheme The low heat design scheme refers to reducing the heat generation by reducing the emission spectrum width of the phosphor.

7. High luminous efficiency scheme High luminous efficiency scheme refers to adding more phosphor particles in the same light-emitting area to achieve high luminous efficiency.

8. Compactness Compactness refers to the ability to reduce a complete system to the smallest size, which is called the compactness of the system.

9. Economy and practicability Economy and practicability are two important indicators for evaluating a product, and they are also one of the two factors that need to be considered when choosing LED products.

10. Environmental performance LED is a representative product of green energy, so its environmental performance has also attracted people's attention

11. Service life Long service life is one of the important criteria to measure the quality of a led product.

12. Ease of installation A good product design should take into account the ease of installation.

13. Security Security is the most basic element that people should consider when buying and using any kind of commodity.

14. Recyclable rate Recyclable rate refers to the percentage of the product that can be reused or reused after being scrapped
