Description

A kind of structure that solves the lighting angle dark space

Technical field

The utility model relates to a kind of illumination component, relates in particular to a kind of fitting structure that can solve the lighting angle dark space.

Background technology

For making the LED light fixture not produce dazzle, rising angle is bigger, and prior art adopts the column transmissive mirror.Disclose a kind of encapsulating structure of column LED light source as Chinese patent 101634433, comprised metal substrate, its center has depressed part; Led light source is arranged in depressed part; Column has board structure on it, and the positive pole and the negative pole of led light source pass from substrate respectively.Adopt structure of the present utility model, can make the brightness and the lighting angle of the light that column LED light source sends better, illuminating effect is better.The lighting angle of above-mentioned technology generally can only be in 120 degree scopes, and column transmissive mirror top is downward reflectively can produce the dark space.

Summary of the invention

The utility model mainly is to solve the existing in prior technology deficiency, thereby develops a kind of structure that can solve the dark space of throwing light on, and makes the LED light fixture not produce dazzle, dark space, and rising angle is bigger, and light is softer evenly, solves the fitting structure of lighting angle dark space.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of structure that solves the lighting angle dark space, the printed wiring board that has driving power and be electrically connected with driving power, it is characterized in that: comprise radiator, the heat-conducting block that contacts with radiator is housed in the radiator, aluminium base with the heat-conducting block plane contact is arranged on the heat-conducting block, aluminium base is provided with illuminator B, illuminator B outside is connected with the printing opacity post, described printing opacity capital face is provided with the arc surface of indent, one deck reflector layer is arranged on the described arc surface, described reflector layer can be to film or the plated film layer, on the arc surface of printing opacity capital face, be connected with illuminator A, described illuminator A can make somebody a mere figurehead on the arc surface or in the middle of the arc surface, described illuminator A, illuminator B is electrically connected with driving power.

The technical solution of the utility model can also be further perfect:

As preferably, in the middle of the described printing opacity post axially extending bore is arranged, the upper end of described through hole is communicated with arc surface.

As preferably, there is inner concave (cavity) described printing opacity post lower surface, and described inner concave is positioned on the projection surface of illuminator B.

As preferably, described radiator is outer to be the heat conduction plastic cement, internal layer setting-in aluminium, and the two one-shot forming processes.

As preferably, described radiator is a metal material.

The beneficial effects of the utility model are:

The utility model is improved the light emission direction of column light source and illumination effect by changing the setting of existing column LED light source.

1, rising angle is increased to greater than 270 degree;

2, the utility model has increased additional illuminator at output optical zone, has solved the bright dipping dark space;

3, vision protection has been avoided the direct projection dazzle of LED lamp, does not have the dark space, and light is softer evenly, does not produce kopiopia.

4, environmental protection does not contain ultraviolet ray and infrared ray, does not produce radiation.
