Abstract

A strip LED lamp comprises a metal base plate and three or more than three LED chips, wherein the metal base plate is provided with a module line layer, the LED chips are arranged on the module line layer in a matrix series-parallel connection way, and are arranged on the metal base plate in equal interval, high heat-conducting glue is arranged between the LED chips and the metal base plate, and high heat-conducting glue is also arranged on the module line layer and the metal base plate, a reflecting frame is arranged on the periphery of the LED chip region on the metal base plate, a refracting surface is arranged on the inner surface of the reflecting frame, a transparent colloid is arranged in the reflecting frame, and a location mounting groove is arranged on the base plate. With the structure, the irradiation region of the lamp can be changed, the part of circuits can be completely separated from the part of radiation, therefore, the use is safe, the installation of the LED chips is firm, and the radiation of the lamp can not be affected.

Description

A kind of strip LED lamp

Technical field

The utility model relates to a kind of LED lamp, especially LED illuminating lamp.

Background technology

Along with developing rapidly of LED lamp, its technology is being applied in the daily illuminating lamp gradually also, and now, people in use, and are also more and more higher to the requirement of lamp, such as heat radiation situation, brightness, service life etc.At present, the patent No. is 200720008026.6 to have disclosed a kind of led light source, comprise some led chips, this led chip adopts matrix-style serial, parallel way to be bundled on the metal substrate, led chip is encapsulated with a clad outward, be provided with microscope carrier between metal substrate and led chip, microscope carrier comprises the metal forming on upper strata and the insulating barrier of lower floor.The LED light irradiation distance of this structure is longer, and the irradiation of light is even, and volume is little, but the direction of illumination of its light can not be changed as required.

Summary of the invention

The purpose of this utility model is for a kind of strip LED lamp is provided, and utilizes the utility model can change the irradiation area of lamp as required, and circuit part and radiator portion are separately.

For achieving the above object, strip LED lamp of the present utility model comprises metal substrate and the led chip more than three or three, metal substrate is provided with the module line layer, led chip adopts the series-parallel system of matrix form to be located on the module line layer, led chip is to be installed on the metal substrate by the mode that equi-spaced apart is arranged, can guarantee the uniformity consistency of LED lamp wiring, be provided with the bonded adhesives of high heat conduction between described led chip and the metal substrate, also be provided with high heat conduction bonded adhesives on module line layer and the metal substrate, led chip is to be connected on the module line layer by gold thread, the periphery in led chip zone is provided with reflection box on the described metal substrate, the inner surface of reflection box is provided with plane of refraction, is provided with the printing opacity colloid in the reflection box.

Adopt this structure, owing to be provided with reflection box on metal substrate, reflection box is provided with plane of refraction, and described plane of refraction can change the direction of light of sending, thereby changes the irradiation area of lamp; Because be provided with the bonded adhesives of high heat conduction between led chip, module wiring board and metal substrate, its circuit part is separated fully with the metal substrate that is used to dispel the heat, and described bonded adhesives is highly heat-conductive material, like this, and practical safety, and radiating effect.

As improvement, described metal substrate is provided with the location and installation groove, is convenient to like this install.

Compared with prior art, because led chip is to be installed on the metal substrate by the mode that equi-spaced apart is arranged, therefore, can change the uniformity consistency of light; Owing to be provided with reflection box, and reflection box is provided with plane of refraction, therefore, can change the irradiation area of lamp; Owing to be provided with high heat conduction bonded adhesives, circuit part and radiator portion are separated fully, therefore safe in utilization, the installation of led chip is firm, and does not influence the heat radiation of lamp.
