Description

Background
In the application of the existing linear light source, a low-power lamp is gradually changed into a high-power lighting lamp, the power is improved, and the requirements of temperature control and heat dissipation are also improved for an LED light source.
In order to avoid the damage of the components in the electronic product due to high heat, the conventional heat sink is mainly made of metal with good thermal conductivity, light weight and easy processing (for example, most of the heat sinks are made of aluminum, copper or silver, but silver is a noble metal with high unit price and is therefore less used for the heat sink), wherein most of the heat sinks are mainly made of aluminum alloy with high conductivity and have moderate cost, the production process of the heat sinks includes extrusion, stamping, die casting, etc., and the heat sinks are mostly used for modules extending in a straight line, which can provide an effective heat dissipation mode for the lamp.
In addition, the conventional lighting products are mainly point light sources or surface light sources, and the main heating area and heat dissipation mechanism thereof also need to conduct the high-power fast temperature corresponding to the point and surface to the heat sink. Therefore, most of the conventional lighting products are configured with the conventional heat sink, the spot light source or the surface light source can generate extremely high brightness, but the configuration of the heat sink is low, so the shape of the lamp is limited due to the heat sink.
In addition to the conventional lighting products, there is another decorative strip, which is packaged by a soft material and therefore lacks a heat sink structure, compared to the conventional lighting products, although the decorative strip has higher flexibility in shape, the power and brightness of the light source cannot achieve the purpose of legal lighting or light distribution of the car lamp, the linear light source is characterized by having a similar modularization characteristic when extending linearly, and the light source can be continuously and repeatedly arranged to achieve the required shape and length.
Meanwhile, in order to prolong the service life of the high-power lamp and achieve a good lighting effect, the high-power lamp needs to be used in combination with the heat sink, and high heat generated by the LED is guided to the environment outside the lamp by the heat dissipation structure, so that the heat sink is often used for guiding heat in the conventional LED lamp.
However, if the heat sink is applied to a light bar or a lamp with a special shape (e.g., a curve shape or a wave shape), the total length and width of the applied heat sink may be close to the maximum dimension of the light bar, which results in a requirement of a specific mold size, a special production machine and a higher production cost, if the heat sink is manufactured into a composite type, the heat sink itself needs to change the dimension of the heat sink or manufacture a special angle according to the shape of the special shape, and thus the production advantages of the heat sink that can be used repeatedly in a modularized manner are lost.
Therefore, the invention provides a heat dissipation structure which can be used for a light source module with a special shape or a linear light source module, the heat dissipation structure is manufactured by using aluminum alloy with light weight and low cost, and a plurality of heat dissipation structures are connected with each other to form a nonlinear structure, so that the heat dissipation structure can be applied to the light source module with the nonlinear shape.
