Description
Technical field
The utility model relates to a kind of guard rail lamp, relates in particular to a kind of LED guard rail lamp.
Background technology
guardraillamp is outdoor scene brightening important component part, being mainly used in entirety beautifies and highlights effect unique, it is current bridge, the main powder tool of the brightening such as megastore, the LED guard rail lamp using at present has the following disadvantages: the one, LED radiating effect is bad, affects its service life, and the epoxy resin in the 2nd, LED is easily subject to ultraviolet interference, after working long hours, resin slowly becomes muddy, affects luminous efficiency.
Utility model content
The purpose of this utility model provides a kind of good heat dissipation effect for above-mentioned situation exactly, long service life, the LED guard rail lamp that luminous efficiency is high.The purpose of this utility model can realize by following scheme: a kind of LED guard rail lamp, comprise PC outer tube, LED light source assembly, the two ends of PC outer tube are provided with end cap and joint, described LED light source assembly is connected with joint by wire, it is characterized in that described PC outer tube the inside is provided with draw-in groove, described LED light source assembly is stuck in draw-in groove, described LED light source assembly comprises aluminium base and LED, described aluminium base is strip, by copper foil circuit plate, three layers of composition of heat conductive insulating layer and aluminium sheet, upper strata is copper foil circuit plate, bottom is aluminium sheet, heat conductive insulating layer is between copper foil circuit plate and aluminium sheet, aluminium base is provided with several bowl-type grooves, the bottom of bowl-type groove is on aluminium sheet, described LED comprises chip and fluorescent material, chip is fixed on the aluminium sheet of bowl-type groove bottom, fluorescent material is located on chip, copper foil circuit plate is connected by gold thread with chip, because chip is directly installed on aluminium sheet, without passing through heat conductive insulating layer, but directly directly dispel the heat by aluminium sheet, in addition, copper foil circuit plate not only conducts electricity, can also distribute a part of heat by the gold thread that connects chip, greatly improve the radiating effect of LED, extend the service life of LED, in addition, bowl-type groove the irradiating angle that can strengthen LED is set, do not re-use epoxy resin, make to work long hours and also can not affect the luminous efficiency of LED.The utlity model has simple in structure, good heat dissipation effect, long service life, luminous efficiency high.
