Problems solved by technology

There are mainly three types of packaging for LEDs: dispensing, potting, and molding. The problem of black spots on LEDs lies in the above-mentioned manufacturing process. Black spots will cause multiple lithography of the light emitted by the LEDs, which will affect the lighting effect.

Embodiment Construction

[0031] see figure 1 Referring to FIG. 4 , the present invention provides a lighting device, which includes a lampshade 1, a socket 2, a light guide plate 3, a reflective layer 4 and a plurality of substrates 5. In this embodiment, the lampshade 1 is made of aluminum However, it can also be made of other metals with good heat dissipation. The lampshade 1 is bowl-shaped, with a first opening 11 that penetrates up and down in the center. Fin-shaped cooling fins 12 , the cooling fins 12 extend from the first opening 11 toward the peripheral edge of the lampshade 1 .

[0032] In this embodiment, the receiving base 2 is made of aluminum, but it can also be made of other metals with good heat dissipation, and the receiving base 2 is in the shape of a polygonal cylinder. The top edge of the receiving base 2 extends inward to form a fixing portion 21 , and the fixing portion 21 is locked in the lampshade 1 by a plurality of screws 6 and is close to the first opening 11 . The peripher...

Abstract

An illuminating apparatus comprises a lampshade, a socket seat, a light guide plate, a reflecting layer and a plurality of base plates, wherein, the socket seat has tube shape and is installed inside the lampshade; the light guide plate is used for mixing light and is arranged between the lampshade and the socket seat; the reflecting layer is arranged between the lampshade and the light guide plate; the base plates are respectively provided with an LED and arranged on the socket seat; in this way, a light source is emitted to the reflecting layer from smaller area, and is expanded to be larger area by the reflection of the reflecting layer, so as to overlap in the light guide plate to achieve the effect of mixing light, thus leading point light source to be translated into surface light source.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device which uses a light-emitting diode (LED) to illuminate, increase the brightness of the light source and make the light source clearer. Background technique [0002] The traditional tungsten filament lamp emits light in a diffuse state, so it can produce a certain degree of brightness for its surrounding environment, but the traditional tungsten filament lamp has the disadvantage of power consumption. In view of this, there are power-saving light-emitting diodes (LED) has gradually replaced the traditional tungsten lamp. [0003] However, the light emitted by the existing light-emitting diodes is linear rather than diffuse, and the linear light can only be converged at one place, and other surrounding ambient light cannot be converged, resulting in insufficient brightness. [0004] In view of this, there are some people in the industry to propose improvements, such ...
