Problems solved by technology
In order to improve the brightness and heat dissipation performance of the existing LED lights, multiple reflector units are arranged on the lamp body, and there are heat dissipation gaps between the reflector units. This method increases the brightness of a single reflector and improves the heat dissipation performance. Since the LED light source has a certain light angle, the reflective bending edge will block the light source from illuminating the adjacent reflector units, and the existence of the heat dissipation gap increases the distance between the adjacent reflector units, which will inevitably make the The light between adjacent reflector units cannot overlap, resulting in dark areas illuminated by LED lights, seriously affecting the lighting effect

The invention relates to an LED (light emitting diode) lamp. The LED lamp comprises a radiator; and a radiating cavity is formed on the radiator. The technical point of the radiator is that: a radiation separate part is arranged on the radiator; a radiation column upwards extends on the radiation separate part; a plurality of radiation guide slots communicated with the radiating cavity are formed on the radiation column; a circuit board is arranged in the radiation guide slot; an LED bead is arranged on the circuit board; a lamp shade is arranged on the radiation separate part; the circuit board downwards stretches out the lower end of the radiation separate part; an electrical connecting plate which is electrically connected with the circuit board is arranged at the lower end of the radiation separate part; and a power supply connection contact is formed on the electrical connecting plate. The LED lamp is simple in structure, excellent in radiation performance, excellent in lighting effect of the lamp, free of dark areas and simple in circuit wiring.
Description
【Technical field】 [0001] The invention relates to an LED lamp. 【Background technique】 [0002] LED lamps are widely used for their high efficiency, low consumption, energy saving, environmental protection, and long service life. When designing LED lamps, heat dissipation and luminous brightness are mainly considered. In order to improve the brightness and heat dissipation performance of the existing LED lights, multiple reflector units are arranged on the lamp body, and there are heat dissipation gaps between the reflector units. This method increases the brightness of a single reflector and improves the heat dissipation performance. Since the LED light source has a certain light angle, the reflective bending edge will block the light source from illuminating the adjacent reflector units, and the existence of the heat dissipation gap increases the distance between the adjacent reflector units, which will inevitably make the The rays of light between adjacent reflector unit...
