At present, the heat that lamp sends is dissipated by a series of radiant body, described radiant body is complicated and add the cost of product, therefore expect a kind of lighting device can avoiding described not convenient newtype, and such lighting device that exploitation has a preferred housing is main purpose of the present invention.

With reference to the current state of prior art; can point out; although commercially have type and the model of the multiple lighting device that we pay close attention to here, the applicant at least do not know to have with the application present and state those similar technology, structure or the feature protected.

Summary of the invention

As described in the title of this description, the present invention relates to a kind of lighting device, it has the following some advantages with substantial improvements structure that will describe in detail and novel feature, and this lighting device estimates and has remarkable novelty under current prior art condition.

Specifically object of the present invention concentrates on a kind of lighting device, it comprises LED or other lamp that heat dissipates towards their rear portions as source or light source, and be structurally designed to the dissipation contributing to described heat, avoid any negative effect to each element forming illuminating equipment.

The lighting device proposed as the present invention of ideal solution achieves above mentioned object satisfactorily, and it has novelty in its application, and its distinguishing characteristics summarized by claims of this document ending.

Particularly, having explained lighting device of the present invention in previous section is so a kind of device, and the source that its housing design becomes to comprise or light source are on rear side of them, produce the LED of heat or similar lamp.The uniqueness of the shell structure design of this improvement is it comprises the space contributing to described dissipate heat.

Thus, according to the first characteristic of the present invention, in question lighting device has the housing comprising two regions, this bottom at lighting device, one, two regions, be suitable for inserting the lamp socket with light source, another is at top, is used for supporting some assemblies of such as power source and so on.

These two parts can on same section or can not on same section, and they are separated by least one abutment, described abutment such as partition wall or spacer body, for limiting at least one intermediate space between region, upper and lower.

The heat that lamp in lower area produces distributes towards upper area, and containing at upper area may by some assembly of high temperature failure.

Heat is through the intermediate space opened wide before arriving the upper area towards at least side of housing, and therefore the one side or the multi-lateral of opening wide of the illuminated device of a part of heat instead of the upper area of lighting device have distributed.

Also wanting ben is, described intermediate space comprises it highly towards the open spaces that the direction of housing open side increases, therefore open spaces defines the structure of approximate wedge shape, it contributes to the circulation of the heat from lower housing portion region, some lamps are contained in the housing towards described side, therefore, a part for heat have left housing and does not affect upper area.

Similarly, according to another bells and whistles of the present invention, lighting device has air chamber at upper area, contains some assemblies at upper area.This air chamber is separated the lower bottom part of described assembly from the described upper area of housing by this way, namely described power source is moved to farther and is more preferably the heat produced with the lamp being positioned at lower housing portion region and keeps apart.

In a preferred embodiment of the invention, described air chamber is limited by the gripper shoe it comprising some assemblies.

Accompanying drawing explanation

In order to supplement description described herein, and helping to understand better the object of feature of the present invention, adopting and illustrating and non-limiting way, using the scheme as a application's part after investing description, illustrate as follows by reference to the accompanying drawings:

Fig. 1 shows perspective view and the sectional view of an example of the embodiment of the lighting device as the object of the invention, is wherein appreciated that critical piece and its composed component, and it configures and arranges form; And
