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

Embodiment Construction

[0047] In order to facilitate the understanding of the present invention, the LED spotlight of the present invention will be described in a more comprehensive manner with reference to the relevant drawings. The preferred embodiments of the invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0048] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time.

[0049] Unless otherwise defined, all technical and scientific te...

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, LED light efficiency is mainly restricted by the photoelectric conversion efficiency of LED, LED package light loss, and poor heat dissipation of LED lamps. The first two losses mainly depend on the current LED manufacturing process and the selection level of materials, and are increasing at a rate of more than 20% per year over time. The poor heat dissipation of LED lamps has been hindering the improvement of light efficiency and is the biggest bottleneck of the LED industry. [0003] Traditional LED spotlights usually include a light-transmitting lamp housing, LED components, a power supply, and a metal heat dissipation housing. The LED component and the power supply are housed in the light-transmitting lamp housing, and there is a certain distance between the LED component and the light-transmitting lamp housing. The...
