Abstract

The utility model relates to a fixture formed by light-emitting diodes, which is provided with a circuit and a cooling device, wherein a light source module is provided with a chip and a module protection cavity. The module protection cavity is suitable for protecting the light source module with a large area, and the structure of the module protection cavity with a large area for covering the light source module with the large area is simple. The chip on the light source module does not need to be encapsulated and can be directly exposed in the module protection cavity. When the utility modelis manufactured into a fixture with high power, not only the structure of the light source module can be simplified, but also the manufacturing cost of the product can be facilitated to be lowered.

Description

A kind of Light-Emitting Diode light fixture

Technical field

The utility model relates to the light emitting diode that electricity field uses, and especially relates to a kind of light fixture that is made of light emitting diode.

Background technology

Owing to having advantage low in energy consumption, that brightness is high, light emitting diode obtained using widely.In order to improve the illuminating area of light-emitting diodes, often will be integrated and constitute high power light source with a plurality of Light-Emitting Diodes.

Existing integration mode mainly contains 3 kinds: 1, be encapsulated as pinned or SMD formula LED earlier, again array structure made in this encapsulation; 2, be made into 1 watt to several watts high-power packaging body earlier, again with this packaging array combination with heat sink and circuit; 3, directly with the Light-Emitting Diode chip array on base plate, form power number watt high power module to hectowatt.Though the Light-Emitting Diode light fixture adopts these structures can obtain high power light source.But the production link of this class Light-Emitting Diode light fixture is many, and complex process is unfavorable for reducing the manufacturing cost of product, especially when doing the secondary optics design, is unfavorable for reducing manufacture difficulty and manufacturing cost.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model provides a kind of Light-Emitting Diode light fixture, and it not only is fit to make high power light source, but also has simplified the structure of traditional great power LED lamp.

The purpose of this utility model is achieved in that a kind of Light-Emitting Diode light fixture, comprises circuit and cooling device, and light source module has chip, and light source module has the module protection cavity.

On the basis of technique scheme, the utility model also has following further scheme:

Described chip is positioned at the module protection cavity.

Described module protection cavity is the hermetically-sealed construction cavity.

Described hermetically-sealed construction cavity is an inflatable structure.

Described protection cavity has lens.

Described chip is the ultraviolet light-emitting diodes chip.

Advantage of the present utility model is as follows:

Because light fixture comprises circuit and cooling device, light source module has chip, and light source module has the module protection cavity; The module protection cavity is fit to the large tracts of land light source module is protected, and the structure that large-area module protection cavity covers the large tracts of land light source module is simpler.As, the chip on the light source module need not encapsulation and can directly expose in the module protection cavity.When the utility model was made large-power lamp, not only the structure of light source module can obtain simplifying, but also helped reducing the manufacturing cost of product.
