Abstract
The utility model discloses an LED point light source which comprises a circuit board provided with an LED chip, a connection cable electrically connected with the circuit board, a base which is used for fixing the circuit board and provided with a line groove for the connection cable to be placed and a light permeating hood body which covers the side, opposite to the base, of the circuit board. A first space is formed between the circuit board and the light permeating hood body. A second space is formed between the circuit board and the base. A first through hole for communicating the first space and the second space is formed in the circuit board. A second through hole communicating the second space and the outside is formed in the base. Thus, due to the air circulation action of the first through hole and the second through hole, the temperature in the LED point light source can rapidly change along with the outside temperature. Thus, dew caused by the temperature difference between the inside temperature and the outside temperature will not be formed on the inner surface of the light permeating hood body, the dew is prevented from being in contact with the circuit board so as to prevent a short circuit or burnout of a device and normal working of the LED point light source and safety of the device are ensured.
