Description

The combined light emitting diodes tool

Technical field

The utility model is about a kind of combined light emitting diodes tool, refers to a kind of visual actual installation environmental demand especially and adjusts the combined lamp structure of light angle of flare and light fixture size.

Background technology

Stress environmental protection and in the energy-conservation epoch, volume is little, light emitting diode (the Light Emitting Diode of high brightness, long-life and low power consumption characteristic, be called for short LED), replace conventional bulb gradually, for example: European Union progressively eliminate incandescent lamp bulb, and Australia more will be from 2010 from 2007, the forbidding incandescent lamp bulb, LED will become the main element of light fixture gradually.

Though aforesaid LED possesses various advantages such as low power consumption, high brightness, in the luminescence process, but easily produces high temperature, so during industry design LED light fixture, most likely design heat abstractor, the heat energy of its generation in time is excluded, make LED performance maximum efficiency.

Present common LED light fixture 10, as shown in Figures 1 and 2, it mainly is made up of lampshade 11, drive circuit group 12 and a plurality of LED lamp holder 13 with fin shape outer surface; Being provided with a heat conduction aluminium sheet 111 and described LED lamp holder 13 in this lampshade 11 respectively is installed on this heat conduction aluminium sheet 111, and mat drive circuit group 12 is lighted each LED lamp holder 13, and the heat that LED lamp holder 13 produces because of lighting, to directly be passed to lampshade 11 by this heat conduction aluminium sheet 111, and dispel the heat by the multi-disc fin on these lampshade 11 outer surfaces.

So,, actually use and install when making, but find many following disappearances though above-mentioned fin shape lampshade can effectively be got rid of the heat energy that LED lamp holder 13 is produced:

1. though it is good that above-mentioned fin shape lampshade 11 is used in small size light fixture radiating effect, but when being used in large-sized light fixture, then radiating effect is not good, reason is: required lampshade 11 sizes of large-scale light fixture are bigger and heavy, cause heat energy to be deposited in the lampshade center easily, can't influence LED lamp holder usefulness and life-span easily by discharging smoothly on every side.

2. because the size of light fixture need be looked erecting bed illumination decision in one's power, if adopt aforementioned integrally formed fin shape lampshade, then can't look environmental aspect at any time and change required light angle, industry is the various size of design and for making the LED lamp present the lampshade mould of different diffusion angles in advance, with in response to demand.Because the required irradiation angle of each environment may not be identical, so can't obtain in this way can be corresponding to the light fixture of each environment with a kind of sample attitude, so need design lampshade miscellaneous thereby increase many production costs and stock material, for the industry of stressing low cost, low stock now, sizable room for improvement is arranged in fact.

For this reason, how effectively to improve the LED light fixture, make its visual environment demand adjust the angle of flare and the light fixture size of light fixture, and reason light fixture size impact radiating effect is not the problem of studying intensively for the utility model.
