Novel heat pipe heat radiation structure for LED down lamp

Technical Field

The utility model relates to a radiator technical field, concretely relates to novel heat pipe heat radiation structure for LED down lamp.

Background

The LED down lamp is a product developed by improving the traditional down lamp by applying a novel LED lighting source, and has the following advantages compared with the traditional down lamp: energy saving, low carbon, long service life, good color rendering and high response speed. This is particularly important for structures where the power supply is mounted within the fixture, since the luminous efficiency of the LED decreases as the temperature of the LED increases, so heat dissipation from the LED is very important.

The existing LED down lamp only adopts radiating fins to radiate, the radiating is slowed down, and a lot of influences are brought to the service life and the illumination effect of the lamp.

Reference numerals: the heat pipe comprises an aluminum substrate 1, a heat pipe 2, an accommodating groove 3, a first radiator 4, a first fin 41, a second radiator 5 and a second fin 51.

Detailed Description

The invention will be further described with reference to the following examples.

The utility model discloses a novel heat pipe heat radiation structure for LED down lamp's concrete implementation mode, as shown in fig. 1, including circular shape aluminium base board 1, storage tank 3 that a plurality of intervals were arranged is seted up in aluminium base board 1's front, and equal fixed mounting has in each storage tank 3 to be used for radiating heat pipe 2, specifically, and storage tank 3 is the arc form setting, and is perhaps again, and storage tank 3 is the setting of vertical bar form, and the user can set up according to the thermal gathering condition of lamps and lanterns, further improves rate of heat dissipation. Compared with the prior art, the aluminum substrate 1 is provided with the heat pipes 2 for heat transfer and heat dissipation, and the heat dissipation rate is improved.

As an improvement, the back surface of the aluminum substrate 1 is fixedly connected with a first heat sink 4 and second heat sinks 5 respectively arranged at two sides of the first heat sink 4, the first heat sink 4 includes a plurality of vertical first fins 41 arranged at intervals in a matrix form, the second heat sink 5 includes a plurality of vertical second fins 51 arranged at intervals in a matrix form, and the area of the heat dissipation surface of the second fins 51 is larger than that of the heat dissipation surface of the first fins 41. Two kinds of fins of cooling surface variation in size, it can be arranged rationally according to the position that lamps and lanterns heat produced, further improves the radiating effect, compares with prior art, through setting up first radiator 4 and second radiator 5, arranges the different fin of two kinds of heat radiating area rationally, has further improved radiating speed, has prolonged the life of lamps and lanterns, improves the illumination effect.

Preferably, in order to further increase the heat dissipation rate, the distance between two adjacent second fins 51 is equal to the distance between two adjacent first fins 41, so that the first fins 41 and the second fins 51 are aligned in the horizontal direction, a heat dissipation air duct is formed, and the heat dissipation effect is effectively improved, and the distance between two adjacent first fins 41 is 2.3 mm.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
