Description
Technical field
The utility model relates to a kind of candle taillight, relates in particular to a kind of LED candle taillight.
Background technology
Candle taillight is the important component part of domestic lighting, and its power consumption occupies the very most of of whole domestic lighting electricity consumption, and energy consumption is huge.Domestic lighting candle taillight is mainly traditional halogen candle taillight and energy-conservation candle taillight at present, halogen candle taillight exists heating large, energy consumption conversion is low, Illumination Distribution is uneven, light efficiency is low, dazzle is serious, life-span is short, the shortcomings such as maintenance rate height, and there is illuminated object cross-color in the energy-conservation candle taillight of the second low production upgrading as candle taillight, Illumination Distribution is inhomogeneous, light efficiency is low, the problems such as stroboscopic is serious, at present, the third generation candle taillight adopting is LED candle taillight, existing LED candle taillight has the following disadvantages: the one, LED radiating effect is bad, affect its service life, epoxy resin in the 2nd, LED is easily subject to ultraviolet interference, after working long hours, resin slowly becomes muddy, affect 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 candle taillight that luminous efficiency is high.The purpose of this utility model can realize by following scheme: a kind of LED candle taillight, comprise PC light-guiding shade, conduction heat energy aluminum component, ceramic package, driving power and LED light source assembly, the bottom of ceramic package is provided with screw socket, it is characterized in that the punching press of described conduction heat energy aluminum component is in ceramic package the inside, PC light-guiding shade is stuck in the top of ceramic package, described LED light source assembly comprises aluminium base and LED, described aluminium base is circular, 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, described aluminium base is provided with screw installing hole, be convenient to aluminium base to be arranged on conduction heat energy aluminum component by screw, described driving power is located at the bottom of ceramic package, between LED light source assembly and driving power, with conductor wire, be connected, driving power is connected with conductor wire with screw socket, because chip is directly installed on aluminium sheet, without passing through heat conductive insulating layer, but directly by aluminium sheet, directly dispel the heat, in addition, copper foil circuit plate not only conducts electricity, can also distribute a part of heat by connecting the spun gold of chip, greatly improved the radiating effect of LED, extended 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.
