Description

Technical Field

[0001] The present invention relates to the technical field of LEDs, and particularly to an LED constant current source for nuclear power plants. Background Art

[0002] New light sources need to meet the conditions of being able to simulate natural light, being non-irritating to the human eye, having high luminous efficiency, high electrical energy utilization rate, being environmentally friendly and pollution-free, etc. Light-emitting diodes (LEDs) have the advantages of high efficiency, energy conservation, environmental protection, and long service life. The country advocates green lighting, and has developed rapidly in recent years, gradually replacing traditional light sources and leading the lighting market towards a development trend of high efficiency and energy conservation. Starting from energy conservation, making full use of natural light, designing reasonable lighting switches, adopting advanced lighting sources and efficient lamps, and performing maintenance irregularly, it is possible to save more than 70% of the global lighting energy consumption in the proportion of energy consumption, which alleviates the energy crisis caused by China's energy consumption. With the development of semiconductor materials, the replacement of materials used to manufacture LEDs and the reduction of production costs, each LED product has brought more product categories due to parameter changes, and is widely used in multiple fields such as landscape lighting, automotive lighting, indoor lighting, traffic signal lights, and display backlights. LED drive power supplies have the characteristics of being green, environmentally friendly, and energy-saving. However, the existing LED constant current sources do not meet the requirements in terms of sealing and radiation resistance, and it is easy to cause damage to the LED constant current source due to radiation when directly used in nuclear power plants. Therefore, it cannot be directly used in nuclear power plants. So, we propose an LED constant current source for nuclear power plants to solve the above-mentioned problems. Summary of the Invention

[0019] In the present invention, a rotation groove 8 is formed at the top of the second telescopic plate 15. Mounting grooves 10 are formed on both inner walls of the rotation groove 8.

[0020] Working principle: When radiation protection is required for the constant current source body 2, first start the lead screw motor 9. When the lead screw motor 9 rotates, the first telescopic plate 6 and the second telescopic plate 15 can slide relative to each other, causing the second telescopic plate 15 to move downward. As a result, the first shield 13 and the second shield 14 can be moved downward respectively. After the longitudinal displacement is completed, rotate the turntable. When the turntable rotates, it can drive the rotating shaft 21 to rotate. When the rotating shaft 21 rotates, the gear 22 can be rotated, and then the third telescopic plate 19 can be driven to move through the rack 23. When the third telescopic plate 19 moves, the first shield 13 and the second shield 14 can move away from each other. After the lateral displacement is completed according to the size of the constant current source body 2, install the constant current source body 2 on the base 1, which can effectively protect the constant current source body 2 from radiation and reduce the damage of the constant current source body 2.
