Summary of the invention

For addressing the above problem, the purpose of this utility model is to provide a kind of brightness high, good heat dissipation, the two sharp lamps of automobile-used LED that the life-span is long.

The technical scheme that the invention for solving the technical problem adopts is:

The two sharp lamps of a kind of LED comprise circuit board, are arranged in the control circuit in circuit board front and the lamp holder that LED, two ends are electrically connected, and are provided with the fin that metal material is made at the back side of circuit board, are provided with plastic lamp shade in the light-emitting area of LED; Be provided with the plastic lantern headgear for fixing cooling fins and lampshade between the assembly of fin and lampshade and the lamp holder.The fin that is arranged on back of circuit board can make circuit board dispel the heat effective and rapidly, and control circuit and LED on the described circuit board are at high temperature normally stably worked, and guarantees the life-span of the two sharp lamps of described LED; Light-emitting area at LED is provided with lampshade, can improve on the one hand lighting angle and the illumination effect of light fixture; On the other hand; because the protection of lampshade having been arranged; can prevent produce, in the installation process human body directly touch electrostatic hazard that control circuit and LED on the circuit board cause or because of energising in contact little metalwork and cause short circuit risk; also can prevent in storage, moisture and dust enter potential hazard that light fixture causes and on the impact of lamp life in transportation and the use procedure.

Further, described lampshade and fin two ends are extended with the stator that cooperates with lamp sleeve, and described lampshade is connected stator and is connected with lamp holder by lamp sleeve with the fin two ends.Because fin and lamp holder all are metal materials, the plastic lantern headgear that arranges between lamp holder and fin not only can make things convenient for fixing cooling fins and lampshade, and can guarantee the electrical safety isolation of light fixture.

Further, be provided with the draw-in groove of fixing circuit board on the described fin.Be provided with the draw-in groove of fixing circuit board on the fin, so namely fixing circuit board easily also can make circuit board and fin close contact, guarantees radiating effect.

Further, comprise at least a LEDs on the circuit board.

The beneficial effects of the utility model are: the two sharp lamps of a kind of LED that the utility model adopts, be provided with metal fin and plastic lamp shade, the fin that is arranged on back of circuit board can make circuit board dispel the heat effective and rapidly, control circuit and LED on the described circuit board are at high temperature normally stably worked, guarantee the life-span of the two sharp lamps of described LED; Light-emitting area at LED is provided with lampshade, can improve on the one hand lighting angle and the illumination effect of light fixture; On the other hand; because the protection of lampshade having been arranged; can prevent produce, in the installation process human body directly touch electrostatic hazard that control circuit and LED on the circuit board cause or because of energising in contact little metalwork and cause short circuit risk; also can prevent in storage, moisture and dust enter potential hazard that light fixture causes and on the impact of lamp life in transportation and the use procedure.Be provided with the draw-in groove of fixing circuit board on the fin, so namely fixing circuit board easily also can make circuit board and fin close contact, guarantees radiating effect.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and example.

Fig. 1 is the structure chart of the two sharp lamps of a kind of LED of the utility model.

The specific embodiment

With reference to Fig. 1, the two sharp lamps of a kind of LED of the present utility model, comprise circuit board 1, be arranged in the lamp holder 2 that the control circuit in circuit board 1 front and LED, two ends are electrically connected, be provided with the fin 3 that metal material is made at the back side of circuit board 1, be provided with plastic lamp shade 4 in the light-emitting area of LED; Be provided with the plastic lantern headgear 5 for fixing cooling fins 3 and lampshade 4 between the assembly of fin 3 and lampshade 4 and the lamp holder 2.The fin 3 that is arranged on circuit board 1 back side can make circuit board 1 dispel the heat effective and rapidly, and control circuit and LED on the described circuit board 1 are at high temperature normally stably worked, and guarantees the life-span of the two sharp lamps of described LED; Light-emitting area at LED is provided with lampshade 4, can improve on the one hand lighting angle and the illumination effect of light fixture; On the other hand; because the protection of lampshade 4 having been arranged; can prevent produce, in the installation process human body directly touch electrostatic hazard that control circuit and LED on the circuit board 1 cause or because of energising in contact little metalwork and cause short circuit risk; also can prevent in storage, moisture and dust enter potential hazard that light fixture causes and on the impact of lamp life in transportation and the use procedure.

Further, described lampshade 4 and fin 3 two ends are extended with the stator that cooperates with lamp sleeve 5, and described lampshade 4 is connected the stator at two ends and is connected with lamp holder 2 by lamp sleeve 5 with fin.Because fin 3 all is metal material with lamp holder 2, the plastic lantern headgear 5 that arranges between lamp holder 2 and fin 3 not only can make things convenient for fixing cooling fins 3 and lampshade 4, and can guarantee the electrical safety isolation of light fixture.

Further, be provided with the draw-in groove of fixing circuit board 1 on the described fin 3.Be provided with the draw-in groove of fixing circuit board 1 on the fin 3, so namely fixing circuit board 1 easily also can make circuit board 1 and fin 3 close contacts, guarantees radiating effect.
