Description
Technical field
The present invention relates to a kind of field of illuminating lamps, relate in particular to a kind of LED lamp.
Background technology
As shown in Figure 3, in the prior art, LED lamp IC controller is connected in outside the radiator, and on the lead between junction block and the radiator, inconvenience when using or change needs terminals are sealed off again, connects.In addition, at outdoor mounted LED lamp, the external easy water inlet of IC controller makes inner components and parts short circuit.The irradiation of sunlight also can make the accelerated ageing of IC controller, shortens the life-span.
The miniature components and parts of IC chip on the IC controller are comparatively intensive, and many functions are in long-time dormant state, and are in the power consumption always, and a large amount of LED lamps arranges, and electric damage amount is increased substantially, the waste electric power resource.
At present, the traditional heat sink material of the many uses of radiator on the LED lamp, mainly dispel the heat with copper aluminium, as aluminium base, at first, aluminium base should conduct electricity, heat radiation again, insulating again, that was exactly self-contradictory originally, secondly, aluminium base must be under heat be added to a certain degree situation, break through insulating barrier, just can play the effect of thermal conductance, therefore, heat is not breaking through insulating barrier, in the heat stack, can play the thermal shock of degree once to wafer, aluminium is metal material, a large amount of free electrons is arranged in the metal, and the very light weight of electronics, can transmit heat very rapidly, so metal has bigger thermal conductivity, but need certain wind-force air that convection current is carried out on its surface simultaneously thereby heat radiation is walked to realize in a part of torrid zone on aluminium radiator surface, metal also has the function of thermal capacitance simultaneously, and the heat that the led light source derivation comes has major part and is stored in the aluminium radiator, has only a part of heat on surface to be pulled away because of cross-ventilation, so aluminium radiator passive heat radiation that is relativity, especially summer heat that sunshine shining directly produces absorbed by metal and so just be equivalent to that led light source is round-the-clock to emit light and heat, make led light source be placed in for a long time to cause light decay under the high temperature and accelerate, so that have influence on the frequent of whole light fixture service life and maintenance period.
Summary of the invention
The technical problem to be solved in the present invention has been to provide the LED lamp that a kind of IC is packaged in the radiator, radiating effect significantly reaches IC chip long service life.
For solving the problems of the technologies described above, the present invention realizes by following scheme: a kind of LED lamp, comprise lampshade, junction block and be installed in the interior LED lamp of lampshade, described lampshade is buckled on the radiator, this radiator inside is provided with the IC controller, described IC controller one end connects junction block by lead, and the other end is electrically connected the LED lamp;
Described IC controller comprises the IC chip, and civil power AV110～220V that control inserts transfers the needed low-voltage of LED lamp to and regulates luminosity, holding circuit;
Integrated CRV linear regulator, PW light adjusting controller, power tube driver module, MWP low voltage power devices, the grid setting circuit of external high pressure power device, power device, signal generator in the described IC chip, the CRV linear regulator is connected with the output of power device; The PW light adjusting controller is connected with signal generator; Signal generator connects the grid of MWP low voltage power devices by the power tube driver module; The grid of power device is connected with the grid setting circuit, and output is connected with the input of MWP low voltage power devices.
Further, described radiator is the cylindrical structure of fillet, and its inner hollow is connected with the side anchor ring in the junction block one side of drawing the lead connection, and only leaves wire guide on this face.
Further, described lampshade shell is the metal Al-alloy casing, and this cover top portion is connected with radiator, and the heat that the LED lamp is sent conducts to radiator fast and carries out heat extraction.
Further, described lampshade shell inside is coated with undulatory reflector layer, can make light evenly, the immaculate reflection.
LED lamp IC controller installation of the present invention is changed simple to operation, and its IC chip increases substantially service life, has reduced the power consumption of LED lamp, is that electric power resource is saved electric power.The radiator that adopts graphite to make, heat-conducting effect is remarkable, makes the LED lamp be in the duty of constant temperature all the time, in the service life of having improved the LED lamp, reduces and changes operation.
