Description
Technical field
The utility model relates to a kind of Down lamp, particularly a kind of good heat dissipation, light efficiency height, assembling simple LED Down lamp.
Background technology
The LED Down lamp is to use the New LED lighting source to improve development product on traditional Down lamp basis, has the following advantages with traditional Down lamp contrast: energy-conservation, low-carbon (LC), longevity, colour rendering is good, response speed is fast.The design of LED Down lamp is more attractive in appearance light and handy, and it is unified and perfect to reach the integral body that keeps building decoration during installation, does not destroy the setting of light fixture, and light source is hidden building decoration inside and do not exposed, free from glare, and people's visual effect is soft, even.
Down lamp is to be embedded on the ceiling, and because of its passive heat radiation device places the environment of ventilation condition difference for a long time, the heat that LED is produced can not in time distribute, and causes the LED junction temperature higher, and the LED light decay is serious, the lost of life.
At present, consider the pollution of the dazzle of LED Down lamp generation to environment, big city adopts transmitance frosted diffuser on the low side to carry out light and handles, the surplus light loss of adding part is in Down lamp inside, therefore, whole light efficiency is not high, fails to embody the energy-conservation advantage of LED itself.
The utility model content
The purpose of this utility model is in order to solve weak point of the prior art, a kind of active heat loss through radiation to be provided, secondary optics processing, assembling simple LED Down lamp.
For achieving the above object, the utility model adopts following scheme:
A kind of LED Down lamp, include shell, shell is curved cylindric, and the shell inner bottom part is provided with inside fixed leg, and shell top light-emitting window is provided with bayonet socket, the shell inner bottom part is provided with radiator, radiator is unsettled to be arranged on the fixed leg of shell, and radiator is provided with LED integrated optical source, and LED integrated optical source is provided with reflector, reflector is provided with glare filter, and glare filter is fixed on the shell by the bayonet socket rotation of shell.
[0007]Among some embodiment, described case body periphery has several cross-ventilation mouths therein, and the cross-ventilation mouth is a undercut formula strip through-hole, and bayonet socket is distributed in shell light-emitting window place with 120 °.
Among some embodiment, fixed leg is inwardly stretched out in described shell bottom surface therein, and fixed leg is a cylinder.
Therein among some embodiment, described shell is with metal, polycarbonate or acrylic; LED integrated optical source substrate is aluminium base, copper base, ceramic substrate or graphite substrate.
Among some embodiment, described LED integrated optical source is fixed on the radiator by screw, is provided with heat-conducting silicone grease between LED integrated optical source and the radiator therein.
Among some embodiment, described radiator is made of soaking plate and radiating fin therein, and radiating fin is the number of plate-shaped body, and radiating fin is drilled with fixed via equidistantly vertically to be evenly distributed on the soaking plate on the soaking plate.
Therein among some embodiment, the fixed leg of the fixed via tight fit shell of described radiator, radiator is a graphite material, it is cylindric that radiator is.
Among some embodiment, described reflector is horn-like therein, and the reflector inwall is coated with specular material.
Among some embodiment, described reflector is a specular aluminium therein, or plated film is finished on plastics, polycarbonate.
The utility model adopts the graphite material of heat loss through radiation as radiating mode, in airtight environment, can bigger raising change heat-sinking capability, be particularly suitable for being installed in the LED Down lamp on the ceiling, the case body periphery has some bar shaped undercut through holes, form inlet and outlet, improve cross-ventilation, and prevent that effectively dust from entering lamp interior and reducing heat-sinking capability.The utility model adopts specular material to handle as secondary optics, and it is horn-like that reflector is, and the surplus light of LED is reflected away, and improves light extraction efficiency greatly.
