Problems solved by technology

This will inevitably reduce the area of ​​the light-emitting surface of the LED spotlight, resulting in the disadvantages of the LED spotlight, such as bulky appearance, small light-emitting surface, limited light-emitting angle, and increased cost.
Moreover, the air sealed in the LED spotlight cannot flow, and the thermal conductivity of the air is very low (0.023W / k m), so the heat generated by the LED components and power supply is difficult to conduct to the light-transmitting lamp shell.

Abstract

Disclosed is an LED spot lamp which comprises a light-transmitting housing, a lamp holder, a light-transmitting lampshade, a thermal conductive adhesive support frame, a power supply, a radiator, an LED component and a lens component. The light-transmitting housing is provided with an accommodating cavity, the lamp holder is provided with a containing cavity and sleeves one end of the light-transmitting housing, and the light-transmitting lampshade is arranged at one end, away from the lamp holder, of the light-transmitting housing. The thermal conductive adhesive support frame is fixed on the inner wall of the light-transmitting housing and provided with a mounting cavity which is communicated with the containing cavity. The power supply is fixed in the mounting cavity. The radiator is arranged on the end face, close to the light-transmitting housing and used for connecting with the light-transmitting lampshade, of the thermal conductive adhesive support frame. The LED component is arranged on one side, away from the thermal conductive adhesive support frame, of the radiator. The lens component is arranged on one side, away from the thermal conductive adhesive support frame, of the LED component and fixed on the radiator. The thermal conductive adhesive support frame, the power supply, the radiator, the LED component and the lens component are all accommodated in the accommodating cavity. The LED spot lamp has a large light-emitting surface.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED spotlight. Background technique [0002] At present, the light efficiency of LED is mainly restricted by factors such as the photoelectric conversion efficiency of LED, the light loss of LED package, and the poor heat dissipation of LED lamp. The first two losses mainly depend on the current LED manufacturing process and material selection level, and as time goes by, they are increasing at a rate of more than 20% per year. The problem of poor heat dissipation of LED lamps has been hindering the improvement of light efficiency, which is the biggest bottleneck of the LED industry. [0003] Traditional LED spotlights usually include a transparent lamp housing, LED components, power supply and metal heat dissipation housing. The LED component and the power supply are accommodated in the light-transmitting lamp housing, and there is a certain distance between them and th...
