Abstract
The utility model discloses an LED lamp comprising a power supply, an LED substrate and a radiator, wherein the power supply is electrically connected to the LED substrate which is fixed on the upper end of the radiator, and the power supply is placed in the radiator. The LED lamp is light and is convenient for assembly and high in heat radiation efficiency.
Description
Technical field
The utility model relates to the luminous field of LED, specifically is a kind of bulb of LED efficiently.
Background technology
At present existing, LED is the abbreviation of English 1ight emitting diode (light emitting diode), and its basic structure is an electroluminescent semi-conducting material.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED lamp that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is to be determined by the material that forms the P-N knot.
Existing LED ball bubble is low in luminous efficiency, and weight is big, and caloric value is big, and light decay is big, has a lot of deficiencies.
The utility model content
At the problems referred to above, the utility model aims to provide a kind of good heat dissipation, energy-efficient LED lamp.
For realizing this technical purpose, scheme of the present utility model is: a kind of LED lamp comprises power supply, LED substrate, radiator; Power supply is electrically connected with the LED substrate, and the LED substrate is fixed on the upper end of radiator, and power supply places radiator inside.
As preferably, the louvre of hollow out is arranged above the radiator.
As preferably, power supply is the resistance-capacitance depressurization power supply.
As preferably, the every LED lamp on the LED substrate is 0.2W.
The beneficial effects of the utility model, easy to assembly, the radiating efficiency height, in light weight.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, a kind of LED lamp comprises power supply 1, LED substrate 2, radiator 3.Power supply 1 is connected with LED substrate electricity 2, and LED substrate 2 is fixed on the upper end of radiator 3, and power supply 1 places radiator 3 inside.The diameter that the diameter of aluminium base is put substrate than radiator is very compact, directly forces up with instrument.Power volume is very little, is placed on lamp holder the inside, and like this, power supply and LED distance are big, do not have direct heat-conduction medium, and the heat that LED and power supply conduct each other is few, has improved radiating efficiency.
The louvre that hollow out is arranged above the radiator 3.Utilize the radiator of hollow out to improve radiating efficiency.Power supply is 1 resistance-capacitance depressurization power supply, and it is little that this power supply has a volume, few advantage of dispelling the heat.
Every LED lamp on the LED substrate 2 is 0.2W.
The above; it only is preferred embodiment of the present utility model; not in order to limiting the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, all should be included within the protection domain of technical solutions of the utility model.
Claims (4)
1. a LED lamp comprises power supply, LED substrate, radiator, it is characterized in that: power supply is electrically connected with the LED substrate, and the LED substrate directly is fixed on the upper end of radiator, and power supply places radiator inside.
