Problems solved by technology

[0003] LED floodlights are widely used outdoors. They are used for auxiliary lighting or directional projection at night. They are bright, energy-saving and environmentally friendly. It is easy to cause failure due to overheating of the lamp body, and the outdoor environment is harsher than indoors, so the service life is relatively short and the failure rate is high. However, lighting failures are usually only found when they need to be used at night or in a dark environment. The light does not emit light, and it is difficult for maintenance personnel to accurately judge its installation position, which brings certain difficulties to maintenance

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the LED lamp body 1 is a cylinder, and the exterior of the LED lamp body 1 is provided with a plurality of copper heat dissipation fins 2, and the copper heat dissipation fins 2 are arranged symmetrically along the axial direction of the LED lamp body 1, and the copper heat dissipation fins A luminous coating substrate 3 is provided on the outside of the sheet 2 , a luminous coating 4 is provided on the luminous coating substrate 3 , and a light-transmitting protective shell 5 is provided outside the luminous coating 4 .

[0014] When in use, the copper heat dissipation fins 2 assist in heat dissipation of the LED lamp body. The copper heat dissipation fins 2 have a good heat dissipation effect. The copper heat dissipation fins 2 can also be replaced with aluminum heat dissipation fins, and the heat dissipation effect is slightly worse...

Abstract

The invention discloses a luminescent LED projection lamp, which comprises a cylindrical or prismatic LED lamp body. A plurality of radiating fins are parallelly arranged outside the LED lamp body along the axial direction of the lamp body, a luminescent coating substrate is arranged outside the radiating fins, and a luminescent coating is arranged on the luminescent coating substrate. The luminescent LED projection lamp is mainly used for flood lighting, is simple in structure, fine in radiating effect and capable of emitting light for indicating the position of the lamp failing at night to facilitate examination and repair for maintainers.

Description

technical field [0001] The invention relates to a lighting device, in particular to a luminous LED projection lamp. Background technique [0002] In recent years, the cost of LED consumables for lighting has been gradually reduced, and its performance has been further developed. Compared with traditional light sources, it has advantages in service life, start-up time, stability, safety, and environmental protection. Therefore, it is widely used and used in individual In the field of lighting, it completely replaces the traditional light source. [0003] LED floodlights are widely used outdoors. They are used for auxiliary lighting or directional projection at night. They are bright, energy-saving and environmentally friendly. It is easy to cause failure due to overheating of the lamp body, and the outdoor environment is harsher than indoors, so the service life is relatively short and the failure rate is high. However, lighting failures are usually only found when they need...
