High-efficiency radiating high-power LED spot lamp

Abstract

The invention discloses a high-efficiency radiating high-power LED spot lamp which comprises a bracket (3), a drive power supply (1), a light source wire (2), LED lamp beads (5) and a radiator (6), wherein the radiator (6) consists of a cylindrical basal body (7) and radiating fins (4); a plurality of hole-shaped light source cavities (8) are formed in the center of the basal body (7), and power supply through holes (9) penetrate through the bottoms of the light source cavities to the top of the basal body; and the LED lamp beads (5) are arranged at the bottoms of the light source cavities (8). According to the spot lamp adopting the structure, a radiating structure is arranged, so the spot lamp can adapt to the radiating requirement of high-power working of an LED array and has the advantages of high stability and simple structure and an excellent, more flexible and adjustable light emergent effect.

Description

[0001] technical field [0002] The invention relates to the field of lamps, in particular to a high-power LED spotlight with efficient heat dissipation. [0003] Background technique [0004] Spotlights have the characteristics of high concentration of light. Usually, the angle of irradiation of the emitted beam is less than 30°. It is often used to build modern lighting with no main lights and no fixed scale. It is an important means to create an indoor lighting atmosphere. It has a wide range and various forms. For the application of traditional spotlights, halogen lamps are mostly used, which have disadvantages such as low luminous efficiency, high energy consumption, and short service life. The unidirectionality also forms a perfect support for the light distribution of spotlights, but the traditional spotlight structure is difficult to adapt to the working characteristics of LEDs, especially in terms of heat dissipation.

[0004] Spotlights have the characteristics of high concentration of light. Usually, the angle of irradiation of the emitted beam is less than 30°. It is often used to build modern lighting with no main lights and no fixed scale. It is an important means to create an indoor lighting atmosphere. It has a wide range and various forms. For the application of traditional spotlights, halogen lamps are mostly used, which have disadvantages such as low luminous efficiency, high energy consumption, and short service life. The unidirectionality also forms a perfect support for the light distribution of spotlights, but the traditional spotlight structure is difficult to adapt to the working characteristics of LEDs, especially in terms of heat dissipation. Due to the small power of a single LED and insufficient luminance, it is necessary to use LEDs The array is used as a light source, which leads to the problems of concentrated heat and high local temperature of LED lamps, which can easily lead to unstable circuit control systems and reduced lamp life. At the same time, the traditional spotlight structure can hardly control the light emitted by the LED array Effective control to meet the desired light effect
