Abstract

The utility model relates to an efficient LED lamp, which comprises a lamp panel main body, at least one set of light source and a transparent cover. The light source comprises a circuit board, an LED and a reflector. The reflector comprises one or more slots which are arranged in parallel and have a vertical cross section on the reflecting side as a wide slope or arc side. The top of the slot is provided with a plurality of lamp holes for the LED extending from inner to outer. The slot of the utility model increases the reflection angle so the light can reflect in a wider scope, the better radiation is obtained and the lighting effect is promoted. The top of the reflection cover is provided with various structures so the type of the reflection cover is various. The utility model has the advantages of simple structure, easy processing and low manufacturing cost.

Description

The efficient light fixture of a kind of LED

Technical field

The utility model relates to the illuminating lamp field, specifically is the efficient light fixture of a kind of LED.

Background technology

The LED light emitting diode is little because of its volume, on little power consumption, high brightness, low in calories, long positive extensive use of life-span and the various light fixture.A kind of LED light fixture is arranged in the prior art, its structure comprises lamp panel, circuit board, LED light emitting diode, reflection shield and diffuser composition, wherein the structure of reflection shield is tubaeform, the LED light emitting diode puts in the horn mouth, but the reflection shield of this flared structure mainly plays the optically focused effect, its reflection angle scope is less, and illuminating effect is undesirable.

Summary of the invention

The purpose of this utility model is the problem and shortage at above-mentioned existence, and a kind of spread reflection angular range is provided, and effectively improves the efficient light fixture of LED of light efficiency.

The efficient light fixture of a kind of LED, comprise lamp panel body, at least one group of light source and diffuser, light source comprises circuit board, LED light emitting diode and reflection shield, reflection shield comprises that one or one or more are arranged side by side and the longitudinal section of its reflecting surface roughly is the inclined-plane that magnifies or the elongated slot of cambered surface, the groove top of elongated slot be provided with several for the LED light emitting diode from the interior lamp hole that stretches out outward.

The top structure of reflection shield can have various ways, can be made as the plane as the top of reflection shield, and this plane and two beveled are elongated slot in echelon; Also can be that two reflectings surface of reflection shield are intersected the inverted V-shaped elongated slot; The top of reflection shield also can be made as V-arrangement or be made as to recessed cambered surface.

For improving the stability of placing the LED light emitting diode, reflection shield top is provided with the locating slot that is used to put the LED light emitting diode along the elongated slot length direction.

The corresponding lamp hole of LED light emitting diode is in line fixture on circuit board.Each arrange the LED light emitting diode in series fixture on circuit board, be electrically connected with parallel way then.

The utility model is owing to adopt by reflection shield and comprise that one or one or more are arranged side by side and the longitudinal section of its reflecting surface roughly is the inclined-plane that magnifies or the elongated slot of cambered surface, the groove top of elongated slot is provided with several for the version of LED light emitting diode from the interior lamp hole that stretches out outward, elongated slot has enlarged reflection angle, make light can reflex to bigger scope, simultaneously also reach better radiating effect, thereby effectively improved light efficiency.The top of reflection shield can be set to multiple version, makes the reflection shield various shapesization.The utility model is simple in structure, processing easily, and production cost is low.

Below in conjunction with accompanying drawing the utility model is further described.

The specific embodiment

Shown in Fig. 1-4, the efficient light fixture of a kind of LED of the utility model, its structure is made up of lamp panel body, at least one group of light source and diffuser, wherein light source comprises circuit board, LED light emitting diode and reflection shield, reflection shield 1 comprises that one or one or more are arranged side by side and the longitudinal section of its reflecting surface roughly is the inclined-plane that magnifies or the elongated slot 11 of cambered surface, the groove top of elongated slot 11 be provided with several for the LED light emitting diode from the interior lamp hole that stretches out outward 12.

As shown in Figure 2, the top of reflection shield 1 is provided with the plane, and plane and two beveled are elongated slot in echelon.

As shown in Figure 5, two reflectings surface of reflection shield 1 reflection shield 1 intersect the inverted V-shaped elongated slot.

As shown in Figure 6, the top of reflection shield 1 is made as V-arrangement.

As shown in Figure 7, the top of reflection shield 1 is made as to recessed cambered surface.

Shown in Fig. 2,4,5,6,7, reflection shield 1 top is provided with the locating slot 13 that is used to put the LED light emitting diode along the elongated slot length direction.The corresponding lamp hole 12 of LED light emitting diode is in line fixture on circuit board.Each arrange the LED light emitting diode in series fixture on circuit board, be electrically connected with parallel way then.

The utility model is described with reference to specific embodiment, but this description and not meaning that is construed as limiting the utility model.Other equivalence made from reference to specific embodiment of the utility model changes, if all can reckon with for those skilled in the art, this variation should belong in this claim institute restricted portion.
