Description

A kind of LED light fixture
Technical field
The utility model relates to a kind of lighting, particularly a kind ofly will make the light fixture of light source of light emitting diode, and this light fixture carries a led driver, can directly connect civil power and make light fixture work.
Background technology
Light emitting diode (light-emitting diode LED) can send the light of certain brightness, and brightness can be regulated by electric current or voltage again, and itself is shock-resistant again, anti-vibration, and glow color is very abundant, and the transition of color is very soft.Simultaneously service life long especially, it is reported life-span of LED lamp be ordinary incandescent lamp 20-30 doubly, be more than 10 times of conventional fluorescent lamps life-span, led light source is than incandescent lamp economize on electricity 87%, than fluorescent lamp economize on electricity 50% simultaneously.Led light source because of have energy-saving and environmental protection, long-life, safety, response is fast, volume is little, rich color, serial distinct advantages such as controlled, the best of falling energy consumption that is considered to economize on electricity realizes approach.Therefore the LED lamp becomes the main force of city lighting, also more and more uses on the lighting simultaneously.Occurred the profile LED bulb similar with incandescent lamp on the market, these LED bulbs all have the bullate lampshade of lamp holder, led light source and protection led light source basically, therefore claim that this light fixture is the LED bulb.Because the required voltage of LED is lower, therefore usually need to be with a driver, in order to guarantee the power supply power supply, be comparatively desirable near driver is installed in the LED lamp.But; the LED lamp is when luminous; led light source and driver usually also have heat to make near it temperature rising, and led light source and driver job insecurity under the situation of higher temperature, and the life-span will shorten; therefore; need carry out thermal insulation protection to led light source and driver, but the driver of traditional LED light fixture there is not the isolation structure design, only is with insulating materials driver to be separated; do not have heat-blocking action, and insulation effect not very reliable.
Summary of the invention
In order to overcome the above-mentioned deficiency of LED light fixture in the prior art, the utility model provides a kind of driver is carried out the LED light fixture that heat is isolated and high pressure is isolated.
The utility model is that the technical scheme that its technical problem of solution is adopted is: a kind of LED light fixture, comprise led light source, cover on the outer lampshade of described led light source, the lamp body of fixing described led light source, for described led light source provides the driver of power supply, whole light fixture is fixed to lamp holder on the lamp socket; Described driver is arranged in the described lamp body and is connected with the power input of described led light source, and described lamp body is installed on the described lamp holder; Also comprise a cage of being made by thermoplastic polyester, described cage is arranged in the described lamp body, be isolated within described lamp body and the described driver between.
The beneficial effects of the utility model are that cage mainly has been anti-high pressure and heat-blocking action.The material of cage is the thermoplastic polyester plastic, and thermoplastic polyester plastic's insulating properties are fine, and when light fixture is struck by lightning or otherwise high-tension electricity when impacting, cage can play a very good protection, and can not damage the electronic devices and components of driver.Heat-blocking action can play protection led light source and led driver.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
Fig. 1 is a utility model embodiment LED light fixture outside drawing
Fig. 2 is the utility model embodiment LED fitting structure decomposing schematic representation.
Fig. 3 is a cage schematic diagram in the utility model embodiment LED light fixture.
Among the figure: 1, lamp holder, 11, locating hole, 2, driver, 3, cage, 31, cap head part, 32, shade partly, 33, pillar, 4, lamp body, 41, aluminium base, 5, light source, 6, screw, 7, lampshade.
Specific embodiment
Embodiment 1, as shown in Figure 1 and Figure 2: the LED light fixture, comprise led light source 5, cover on the outer lampshade 7 of led light source 5, the lamp body 4 of fixed L ED light source 5 for led light source 5 provides the driver 2 of power supply, is fixed to lamp holder 1 on the lamp socket with whole light fixture; Driver 2 is arranged in the lamp body 4 and is connected with the power input of led light source 5, and lamp body 4 is installed on the lamp holder 1; Also comprise a cage 3 of being made by thermoplastic polyester, cage 3 is arranged in the lamp body 4, and driver 2 is arranged in the cage 3.In the present embodiment, 3 pairs of led light sources 5 of cage and driver 2 shield, from two aspect protections, and the firstth, with driver and lamp body 4 electric insulations, the secondth, with driver and led light source heat insulation.Therefore, cage 3 need be made with the insulator of good heat-insulation effect.The preferred polybutylene terephthalate (PBT) of present embodiment (Polybutylece terphthalate; PBT); the PBT insulating properties are fine; when light fixture is struck by lightning or otherwise high-tension electricity when impacting; cage 3 can play a very good protection, and can not damage the electronic devices and components in the driver.In the present embodiment, cage 3 is the carnival hat shape, and as shown in Figure 3, wherein cap head part 31 the inside installation of driver 2 extend in the cylinder of described lamp body 4, and shade partly 4 pillars 33 of 32 is connected with 4 locating holes 11 of described lamp holder 1.Lamp body 4 profiles are cylindric, and arranged outside has fin, lower ending opening, the upper surface closely cooperates and embeds aluminium base 41, aluminium base 41 is fixing by screw 6 with led light source 5, like this, if just being delivered in the air by fin then of distributing of led light source 5 by aluminium base 41.
The design feature of present embodiment is as follows: the light fixture of present embodiment mainly is made up of 6 parts, is respectively lampshade 7, led light source 5, lamp body 4, driver 2, cage 3, lamp holder 1.Lampshade 7 main effect protection led light sources 5, and the light that LED is sent is more even; LED is a light source, but has also produced the main heat of this product simultaneously; Lamp body is except that fixation, and it still is an extraordinary heat carrier, and the heat that can send product timely looses in air, and present embodiment is provided with one deck fin in its periphery; Driver 2 is to provide suitable current and voltage for led light source; Cage can be driver 2 and led light source provides special protection function; Lamp holder is that whole light fixture is fixed on the lamp socket, and is light fixture introducing power supply.Cage 3 mainly has been anti-high pressure and heat-blocking action.The material of cage 3 is PBT plastics, and the PBT insulating properties are fine, and when light fixture is struck by lightning or otherwise high-tension electricity when impacting, cage can play a very good protection, and can not damage the electronic devices and components of driver 2.In addition, general electronic devices and components and led light source work at high temperature all can be shortened its service life, and present led light source and drive operation all can produce a large amount of heats, this isolation can be played the effect of isolating led light source and driver heat, the heat that allows led light source and driver produce mainly passes on the lamp body, loose to air from lamp body again, driver is placed in the middle of the cage, and the temperature here so just is very beneficial for the driver operate as normal far below the temperature of cage outside.
