Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, the utility model is described further:
As shown in Figure 1, a kind of LED projector lamp, comprises columnar lamp cylinder 1, and columnar lamp cylinder 1 bottom outer wall is connected with multiple radiating fin 11.
As shown in Figure 2, a kind of LED projector lamp, comprise columnar lamp cylinder 1, columnar lamp cylinder 1 bottom outer wall is connected with multiple radiating fin 11, fixation reflex lampshade 13 on the inwall of columnar lamp cylinder 1 upper end, is provided with radiating module 14 in the bottom of columnar lamp cylinder 1, and radiating module 14 and radiating fin 11 link into an integrated entity part, above radiating module 14, be connected with luminescence unit 2, luminescence unit 2 is also positioned at a center, end of reflection lampshade 13.
As shown in Figure 3, above luminescence unit 2, the transparent crown top of burner 3 is provided with.The transparent crown top of burner 3 is made up of inner casing 31 and shell 32, is provided with cavity 33 between inner casing 31 and shell 32, is filled with transparency liquid heat exchange medium 34 in cavity 33.Liquid heat exchange medium 34 between inner casing 31 and shell 32 is outwards dispelling the heat after absorbing the heat that sends of LED chip, because the surface area of the transparent crown top of burner 3 is larger, the liquid heat exchange medium 34 of flowing its can the conduction of accelerated heat, also can not affect illuminating effect simultaneously.
As shown in Figure 4, luminescence unit 2 is made up of continuous print V-type mounting groove 24, and the first hypotenuse of each V-type mounting groove 24 is connected with circuit board 21, multiple LED chip 22 that circuit board 21 is connected; Second hypotenuse of each V-type mounting groove 24 is coated with reflectance coating 25, and LED chip 22 is relative with reflectance coating 25 and establish; First hypotenuse and the second hypotenuse junction of each V-type mounting groove 24 are cooling base 26, and cooling base 26 has air vent 23, the air vent 23 on the cooling base 26 of luminescence unit 2 communicates with the heat dissipation ventilation hole 15 on radiating module 14.
