Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0025] see figure 1 and figure 2 As shown, the LED bar-shaped light source 1 of the present invention includes a bar-shaped substrate 2, a plurality of chips 3, a bar-shaped lens 4 and a filling colloid (not shown).

[0026] Please combine figure 2 and image 3 As shown, the substrate 2 can be a metal circuit board or a common circuit board equipped with a heat sink. In this embodiment, a common circuit board is used to embed the strip-shaped light source substrate 2 into the heat sink 6. The strip-shaped substrate 2 is provided with a sink hole 20 for mounting the chip 3. The diameter of the lower hole 200 of the sink hole 20 is larger than that of the upper hole. Hole 201 diameter. A heat sink 6 for heat dissipation is fixed in each sink hole 20 , the heat sink 6 is stepped, and its shape matches the structure of the sink hole 20 . The upp...

Abstract

The invention relates to an LED strip light source, which comprises a strip substrate with a circuit, at least one LED chip, a filling colloid and a strip lens, wherein the at least one LED chip is arranged on the strip substrate and is electrically connected with the circuit of the strip substrate; the filling colloid is used for packing the LED chip; and the strip lens and the strip substrate are mutually matched and form a cavity structure. The strip substrate is provided with a glue injecting hole and an exhaust hole; and the filling colloid is packed into the cavity structure through the glue injecting hole and the exhaust hole. The LED strip light source realizes the package structure by matching the lens with a cavity and adopting a mode of injection glue in the bottom of the substrate; the structure can not only simplify the production process and reduce the production cost, but also can improve the consistency of LED strip light source products and achieve the uniform chromaticity. In addition, the invention also provides a package method for manufacturing the LED strip light source.

Description

technical field [0001] The present invention relates to a semiconductor light source technology, in particular to a structure of a light emitting diode (Light Emitting Diode, LED) strip light source and a packaging method thereof. Background technique [0002] Light Emitting Diode (LED) is a device that releases energy in the form of light by using the change of the energy band level when electrons and holes in semiconductor materials are combined. It has small size, long life, low driving voltage, and low power consumption. With the advantages of low volume, fast response, and good shock resistance, it is a common component in various application equipment in daily life, and it has gradually appeared in every corner of the traditional lighting market. As an important product category of semiconductor lighting sources, bar light sources are increasingly used in various fields. [0003] The existing LED bar-shaped light source is to install a metal frame (or frame of other m...
