Description
Technical field
The invention belongs to LED lamp technical field, be specifically related to the integrated LED lighting of a kind of module.
Background technology
By reputation be called the 4th generation light source LED be a kind of light emitting semiconductor device, the solid state light emitter made from LED has long, advantage such as energy consumption is low, control is very convenient of life-span; Along with succeeding in developing of large power white light LED, lighting engineering is faced with a new revolution.In order to make the LED lamp can adapt to the needs of general illumination, the solid-state illumination light source presses for the problem that solves the unit light flux, experiment confirm, the Output optical power of LED lamp and the relation of drive current are good linear relationship, most of LED work under the electric current more than the 300mA does not have saturated trend yet, utilizes the drive current that improves LED can obtain big luminous flux; But the drive current of LED increases, caloric value is significantly increased, because as heat loss and other non-radiative recombination losses, LED radiant light the loss that will have a resistance of its intrinsic bulk resistor of LED, the junction resistance of a class diode in intracrystalline absorption loss water and internal reflection loss and package interface reflection, make external quantum efficiency not reach 0.1, all these energy losses all will be converted into heat, and the rolling up of heat, make the reduction of LED lamp efficiency and quicken and decay and lose use value, the life-span shortens greatly; Therefore, how high-power LED lamp solves a great problem that heat radiation becomes present LED lamp technical field.
Find by retrieval, existing LED illuminating lamp is to be arranged on the same substrate led chip is integrated basically, be arranged in the heat that LED transmission together distributes and influence each other, and the heat that all led chips distribute all collects in shared fluorescent tube inside, make the fluorescent tube temperature inside unprecedented soaring, worsen the working environment of LED, the result significantly rises the LED junction temperature, and theory and practice all proves, if the LED junction temperature rises 100 ℃, its output 2～3dB that will drop also will impel LED to decrease sharply simultaneously; According to document " GSB-1 type optical fiber leakage alarm authenticating document " record, when LED active area temperature was 80 ℃ and 140 ℃, a kind of degeneration factor β value of tying the face luminous tube was respectively 4 * 10
-6h
-1And 8 * 10
-5h
-1, both differ 20 times, visible LED active area temperature particularly junction temperature for the seriousness of the influence in service life of LED.
The patent of Chinese patent notification number 200996590Y proposes the invention of a kind of LED lamp heat radiation, and it is by the LED fluorescent tube, metal substrate, and the thermal capacitance device, semiconductor chilling plate, fin, radiator fan constitutes.The radiating mode of this LED lamp is too complicated, if be used for outdoor lighting, in case break down, such as the situation that the fan stall takes place, just then keeping in repair becomes a problem.
