Abstract
The utility model discloses a light emitting diode (LED) lamp which comprises a circuit board, a plurality of LED lamp beads welded on one face of the circuit board and a radiator arranged on the other face of the circuit board, and therefore heat dissipation performance of the LED lamp is improved, and service life of the LED lamp is increased. A lamp cover is arranged outside the LED lamp beads, and the lamp cover is fixedly connected with the circuit board. The lamp cover is a light transmitting arc-shaped plate, and emitting angles are increased through the light emitting arc-shaped plate.
Description
Technical field
The utility model relates to a kind of LED lamp.
Background technology
Compare with conventional light source; LED has a lot of advantages: power saving, life-span length, pollution-free, and following light source Development Trend is that the LED lamp will progressively replace traditional incandescent lamp and electricity-saving lamp, becomes the main light source of illumination; But the LED lamp all has a very big deficiency at present; It is insufficient to dispel the heat, and the LED illuminator belongs to semiconductor, and too high temperature can have a strong impact on luminous intensity and the life-span of LED.
Summary of the invention
It is good that the technical problem that the utility model will solve provides a kind of thermal diffusivity, the LED lamp that lighting angle is big.
The utility model is to realize through following technical scheme: a kind of LED lamp; Comprise circuit board, and be welded on the LED lamp pearl of circuit board one side, and be arranged on fin fixing on the circuit board another side; Said LED lamp pearl is provided with lampshade outward, and said lampshade is fastened on the circuit board.
As optimized technical scheme, said lampshade is the printing opacity arc.
The beneficial effect of the utility model LED lamp is: be arranged on fin fixing on the circuit board another side, improved the thermal diffusivity of LED lamp, increased the service life of LED lamp; Promoted the lighting angle of LED lamp through the printing opacity arc.
Description of drawings
Fig. 1 is the structural representation of the utility model LED lamp.
The specific embodiment
See also shown in Figure 1ly, a kind of LED lamp of the utility model comprises circuit board 1; And be welded on circuit board 1 LED lamp pearl 2 simultaneously, and be arranged on fin 3 fixing on circuit board 1 another side, the LED lamp pearl 2 luminous heats that produce are delivered in the fin 3; Utilize fin 3 can improve the thermal diffusivity of LED lamp; Increased the service life of LED lamp, be provided with lampshade 4 outside the said LED lamp pearl 2, said lampshade 4 is fastened on the circuit board 1; Said lampshade 4 is the printing opacity arc, has promoted the lighting angle of LED lamp through the printing opacity arc; General aluminium is as circuit board 1 and fin 3, because the coefficient of heat transfer of copper approximately is 1.7 times of aluminium far above aluminium; The utility model selects for use copper product as circuit board 1; Heat dispersion is better, because the machinability of copper is relatively poor and cost an arm and a leg, the utility model still uses aluminium as fin 3.
The beneficial effect of the utility model LED lamp is: be arranged on fin fixing on the circuit board another side, improved the thermal diffusivity of LED lamp, increased the service life of LED lamp; Promoted the lighting angle of LED lamp through the printing opacity arc.
The above is merely the specific embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
Claims (2)
1. LED lamp is characterized in that: comprise circuit board, and be welded on the LED lamp pearl of circuit board one side, and be arranged on fin fixing on the circuit board another side, said LED lamp pearl is provided with lampshade outward, and said lampshade is fastened on the circuit board.
2. LED lamp according to claim 1 is characterized in that: said lampshade is the printing opacity arc.
