Abstract

A bar-type lamp comprises an outer shell, LED light sources, an LED substrate and a power wire. The outer shell is an integrally-formed bar-type sectional material and provided with sliding grooves; every three LED light sources and one resistor are connected in series to form a light emitting unit, multiple light emitting units and a control circuit of the bar-type lamp are arranged on the LED substrate, and the LED substrate is arranged in the sliding grooves; a copper plate and an aluminum alloy plate are arranged on the LED substrate and attached to a whole through high-pressure forming. According to the LED substrate of the bar-type lamp, the copper plate and the aluminum alloy plate are attached to a whole through high-pressure forming, aluminum alloy has good cooling performance due to the synergistic effect of specific components and contents of the aluminum alloy plate, the resistors are arranged in the light emitting units to limit current flowing through LED lamp bodies so that voltage at the LED lamp body ends can not be too large, cooling performance is further improved, and the service life of the LED lamp bodies is guaranteed.

Description

Technical field: [0001] The invention relates to a lighting fixture, in particular to a strip lamp. Background technique: [0002] LED is an electronic device with diode characteristics that can convert electrical energy into light energy. LED lamps have the most promising development prospects in the lighting field. Their outstanding advantages are: high luminous efficiency. At present, the high-power LED luminous efficiency can reach 120 lumens / watt, and the long-term development can reach 150-200 lumens / watt (incandescent lamps, Halogen tungsten lighting effect is 12-24 lumens / watt, fluorescent lamp is 50-70 lumens / watt, sodium lamp is 90-140 lumens / watt, most of its electric energy becomes heat loss); the monochromaticity of light is good, the spectrum is narrow, It can directly emit colored visible light without filtering; it consumes less power. Under the same lighting effect, the power consumption is one-eighth of incandescent bulbs and one-half of fluorescent tubes;...
