Problems solved by technology

But this downlight can only adjust the irradiation angle in one direction, such as figure 1 indicated by the middle arrow
In addition, in this downlight, space must be left for the light engine and the heat sink to adjust the angle by swinging, which limits the size of the heat sink, and the housing cannot play the role of the traditional downlight that cannot adjust the irradiation angle. Heat dissipation, so its heat dissipation effect is poor
[0005] Therefore, the current downlight cannot meet the requirement of adjusting the irradiation angle in multiple directions in some occasions.

Embodiment Construction

[0023] The downlight of the present invention will be described in detail below in conjunction with the preferred embodiments shown in the accompanying drawings.

[0024] Such as figure 2 with image 3 As shown, according to a preferred embodiment of the present invention, a downlight 10 capable of adjusting the irradiation angle in multiple directions is provided. The downlight 10 includes: an outer cover 11 ; a radiator 12 ; and a light engine 13 located between the outer cover 11 and the radiator 12 .

[0025] Figure 2-3 The downlight 10 shown overall has a cylindrical profile. However, it should be understood that the present invention is not limited thereto. The downlight of the present invention can also have outlines of other shapes, such as square, polyhedral and so on. For the convenience of description, in this application, only a downlight with a cylindrical outline is taken as an example for illustration.

[0026] Such as figure 2 , 3 As shown, preferabl...

Abstract

The invention relates to a down lamp capable of adjusting irradiation angle multi-directionally, which comprises a hood, a radiator, and a light engine, wherein the light engine is positioned between the hood and the radiator, at least part of the light engine is spherical; the radiator is provided with a semi-spherical inner surface matched with the spherical part of the light engine; the hood is arranged together with the radiator by an elastic stretching component, thus leading the semi-spherical inner surface of the radiator to contact with the spherical part of the light engine; the down lamp further comprises a pin arranged near the elastic stretching component, one end of the pin is fixed on the radiator, the other end of the pin is extended to penetrate through the hood, the elastic stretching component is further stretched by pressing the pin end penetrating through the hood, so as to separate the radiator from the light engine, thus further being capable of randomly adjusting the irradiation angle of the light engine.

Description

technical field [0001] The present invention relates to an illuminating device, and more specifically, relates to a downlight capable of adjusting the irradiation angle in multiple directions. Background technique [0002] Downlight is a common indoor lighting device, which is widely used in offices, auditoriums, shopping malls, etc. Usually, downlights are installed in the ceiling or wall in a recessed way, so as to maintain the unity and perfection of architectural decoration. [0003] Most of the current downlights cannot adjust the irradiation angle after installation, and can only irradiate the light beam along one direction. [0004] Recently, downlights with adjustable irradiation angles have also appeared, such as figure 1 shown. exist figure 1 In the downlight shown, the light engine is inseparably combined with the heat sink, which is connected to the housing through a pin, and can be rotated around the axis of the pin to adjust the angle. But this downlight c...
