Problems solved by technology

These LEDs are arranged linearly and evenly, and because the LEDs emit light from one side, the irradiation angle and range of the LED module are easily limited by the type of LEDs used, the irradiation range is relatively narrow, and the lighting effect is not good.

Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the LED module with heat dissipation structure of the present invention includes a heat sink 10 and a plurality of LED units 30 attached to the heat sink 10 .

[0014] The radiator 10 is integrally formed by extrusion, and includes a heat conduction seat 12 and a plurality of heat dissipation fins 14 extending outward from the heat conduction seat 12 . The cross-section of the radiator 10 is roughly trapezoidal. The heat conducting seat 12 is substantially V-shaped. The heat conducting base 12 has a first heat absorbing portion 122 and two second heat absorbing portions 124 obliquely extending outward from opposite sides of the first heat absorbing portion 122 . Each second heat absorbing portion 124 includes several steps (not shown). The first heat-absorbing portion 122 has a planar first heat-absorbing surface (not shown) for attaching the above-mentioned LED unit 30 . Each step of the second heat absorbing portion 124 ha...

Abstract

The invention relates to an LED module provided with a heat dissipation structure, comprising a radiator and a plurality of LED units which are closely arranged on the radiator, the radiator comprises a heat-conducting seat and a plurality of heat dissipation fins which extend out from the heat-conducting seat; the heat-conducting seat is provided with heat-absorbent surfaces facing different directions; the LED units are closely arranged on the heat-absorbent surfaces and radiate toward different directions, so that the beam angle and beam scope of the LED module can be expanded.

Description

technical field [0001] The invention relates to a light emitting diode module, in particular to a light emitting diode module with a heat dissipation structure. Background technique [0002] As an efficient light source, light-emitting diodes have many characteristics such as environmental protection, high brightness, power saving, and long life, and have been widely used in various fields. However, LEDs will generate a lot of heat when they work, especially for some high-power LEDs used for lighting. If the heat is not dissipated in time, overheating will easily occur, which will lead to a decrease in luminous efficiency. [0003] In order to dissipate the heat generated by the light-emitting diodes in time to maintain their normal operating temperature, a number of light-emitting diodes are usually attached to a heat sink to form a light-emitting diode module with a heat dissipation structure. The light-emitting diode module is based on actual needs. Used in different lig...
