Abstract
The invention relates to a large-power LED combined lamp which comprises a cooling shell, a lens and a light source. The cooling shell is sequentially provided with a center cooling unit and a lamp shell cooling unit from front to back; the back of the lamp shell cooling unit is connected with a rear cover; a power supply cooling unit which is connected with the rear cover is arranged in the lamp shell cooling unit; the front part of the center cooling unit is provided with a empty cavity for holding the light source and the center of the center cooling unit is provided with a cooling hole which can communicate the empty cavity with the power supply cooling unit; and a plurality of cooling fins are evenly arranged on the back side of the lamp shell cooling unit along the circumferential direction. In the invention, by adopting the combination of a plurality of cooling units, the outside lamp shell functions as both a shell and a cooling unit, and thus, the lamp can be combined with a large-power LED light source and can meet the requirement of an LED on quick cooling and greatly improve the luminous decay, the service life and the like of the LED.
Description
(1) technical field
The present invention relates to a kind of large-power LED combined lamp.
(2) background technology
For thousands of years, the mankind chasing always bright from the ancient times----drill wood to make fire, kerosene lamp, to the incandescent lamp bulb of Edison's invention, fluorescent lamp that the Cloud invents, step by step, the mankind are pursuing more efficient, lasting lighting system.Get into 21st century, people turn to energy-conservation more sight and environmental protection.Great power LED (light-emitting-diode) tube core is the appearance of the light emitting semiconductor device of light source; Become the revolution again on the human illumination history; Progressively replacing traditional lighting light; March toward the LED epoch, countries in the world are all invested LED market to sight, and China has also started huge " the national semiconductor lighting engineering " of scale of investment in June, 2003.Therefore its application is faced with great market prospects.Receiving the huge market attracts and the social development needs; China domestic manufacturers get into LED market one after another; But receive limitation of the technology, the application luminaire product quality is uneven on the market, and the light fixture conversion efficiency is low, loss big, the efficiency of light energy utilization is not high; And factors such as most conventional light source light fixture that adopts is reequiped on the market, and degree of protection is low, volume is big, the light fixture conversion efficiency is low.Limit characteristics such as the LED volume is little, light efficiency height, seriously influenced its development and popularization.Therefore the exploitation and the commercial application of large-power LED combined lamp seem more urgent and important.
See to such an extent that the LED light fixture is generally and wants that conventional lamp is reequiped or be cast into product according to the conventional lamp style design on the existing market.The former is because of adding that with the lamp housing of buying on the market radiator is assembled.Radiating effect with utilize the extremely low and the most basic light fixture degree of protection of light efficiency all not reach.Though and the latter is through autonomous Design; But because of accomplishing that requirement of shelter must be closely; In a sealed space, the heat that both sides' device is distributed intersects each other simultaneously for led light source and power supply, has seriously influenced the requirement of led light source to heat radiation; It is too high to become internal temperature, has quickened the service life of light source light decay and power supply.Simultaneously aspect safeguarding, because of power unit, radiator and lamp housing are an integral body, defective such as change poles inconvenience more, thus influenced result of use, do not reach easy requirement.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can cooperates with high-power LED light source, but it can reach easy in each side such as daily production, maintenances.Simultaneously effectively distribute heat, reduce the light decay light loss, improve the large-power LED combined lamp of service life, light extraction efficiency.
A kind of large-power LED combined lamp; Comprise heat-dissipating casing, lens and light source; Described heat-dissipating casing is disposed with center heat-sink unit and lamp housing heat-sink unit from front to back; Lamp housing heat-sink unit back is connected with bonnet, and lamp housing heat-sink unit inside is provided with the power supply heat sinking unit that is connected with bonnet, and heat-sink unit front portion, center is provided with the cavity that is used to place light source; Center heat-sink unit central authorities have the louvre that cavity is communicated with the power supply heat sinking unit, and described lamp housing heat-sink unit drosal part is along circumferentially evenly being provided with some fin.
Preferably, said heat-dissipating casing is octagon generally.
Preferably, described lamp housing heat-sink unit, center heat-sink unit and lens are fixing through being threaded.
Preferably, heat-sink unit cross section, described center is arcuation, and the lamp housing heat-sink unit is made up of longitudinal component and lateral part, and the cross section, lateral part is the arcuation that cooperates with the center heat-sink unit.
Preferably, described lamp housing heat-sink unit back is provided with groove between each fin.Groove is used for further improving radiating effect.
Combination lamp of the present invention is recommended by the plant equipment machine-shaping through precision of the aluminum of high heat conduction.
The present invention is owing to adopt the combination of a plurality of heat-sink units; Outside lamp housing be shell be again heat-sink unit; Thereby this light fixture can match with high-power LED light source, can satisfy the requirement of LED to quick heat radiating, and LED light decay, service life etc. are increased significantly; Driving power also has independently power supply cooling system in addition, can guarantee and heat that power supply distributes does not mix.Simultaneously can reach the requirement of shelter of external environment condition, characteristics such as conversion light efficiency efficient height to lamp housing.This combination lamp volume only reaches the half the of other products in addition, practices thrift very much cost, and also article are many with the optical lens that only needs to change combination lamp according to actual needs, just can become the product of different occasion demands, satisfy each side's demand.
