Description

A kind of LED lighting fixture

technical field

The utility model relates to lighting technology, in particular to an LED (light emitting diode) lighting fixture.

Background technique

The current LED lights usually use a number of LEDs to be directly welded on a circuit substrate to achieve circuit communication. Luminous surface plus a protective mask.

This overall installation structure makes it inconvenient to change the lamps according to the specifications of the light source, resulting in low production efficiency and high cost, and inconvenient installation and maintenance. A lamp with a protective cover not only affects heat dissipation, blocks light, reduces light efficiency, but also increases weight and cost.

Utility model content

Aiming at the above-mentioned defects in the prior art, the technical problem to be solved by the utility model is to provide an LED lighting fixture which can be conveniently produced, installed and maintained according to requirements, and has good heat dissipation effect and high light utilization rate.

In order to solve the above technical problems, the utility model provides an LED lighting fixture, which includes a rectangular outer frame and a base for installing the light-emitting unit, which is characterized in that the base for installing the light-emitting unit is at least two bars There are gaps between each light bar to form a channel for convection with the outside air, and the two ends of the light bar are respectively fixed on the outer frame.

Further, the outer frame is composed of profiles and connectors.

Further, the outer frame is rectangular, and its four sides are made of aluminum profiles connected by corner connectors at the four corners.

Further, the inner surface of the light bar is provided with a groove for placing a circuit board, and the circuit board is connected to the positive and negative circuits of each light-emitting unit on the light bar; the light-emitting unit is installed on the outer surface of the light bar.

Further, the two side walls of the groove of the light bar are provided with openings with a predetermined length at intervals.

Further, a strip-shaped groove is provided on the inner side of the profile of the outer frame for placing a circuit board, and the circuit board is connected to the positive and negative circuits of each light bar; the back of the groove bottom is fixed to the light bar.

The LED lighting fixture of the present utility model adopts a plurality of strips (called light bars) arranged at a certain distance as the base for installing the light-emitting unit. The quantity can be flexibly set according to the requirements of the LED lighting lamps. The outer frame adopts splicable aluminum profiles to adjust the number and spacing of the light bars accordingly. In this way, in the case of changing the specifications of the LED lighting lamps, there is no need to modify the lamps. The redesign greatly facilitates the production, installation and maintenance of LED lighting. Moreover, since the LED lighting lamp of this structure does not add a protective mask, the distance between each light bar forms a heat dissipation channel that directly convects with the outside air, so the heat dissipation performance is good and the light utilization rate is high.

Detailed ways

The embodiments of the present utility model are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present utility model. All similar structures and similar changes of the utility model should be included in the protection of the utility model. scope.

As shown in Fig. 1-Fig. 3, an LED lighting fixture provided by the embodiment of the utility model includes an outer frame 1 and a base for installing a light-emitting unit. It is characterized in that the base for installing a light-emitting unit is at least two The strip-shaped light strips 2 arranged in parallel to each light strip leave a space (gap) for direct air convection, and the two ends of the light strip are respectively fixed on the outer frame; one side of the light strip 2, That is, the outer side is provided with a light-emitting unit, and the other side, that is, the inner side, is provided with a strip-shaped groove 21 for placing a circuit board; the two side walls of the groove 21 of the light bar are provided with openings of a predetermined length at intervals , forming a number of tooth-shaped structures 22 which are beneficial to heat dissipation.

The four sides of the outer frame 1 are (splicable) aluminum profiles 11, and the four sides of the aluminum profiles 11 are connected by corner connectors 12 at the four corners; the inner side of the outer frame (aluminum profile 11) is provided with a The strip-shaped groove 111 of the circuit board, the bottom of the groove 2 is fixed on the back side; the number, spacing and the number of LED light-emitting units installed on the strip-shaped body 2 can be adjusted and increased or decreased arbitrarily according to needs According to the number and spacing of the light strips 2 of the strip, symmetrical aluminum profiles 11 of different lengths can be selected to make the bearing frame side of the outer frame 1, that is, the frame side used to fix the light bar 2, so that when no In the case of redesigning the lamp, the specifications of the LED lighting lamp can be changed at will, so that the size of the outer frame can be made according to the number and spacing of the required light bars.

Several light-emitting units on each strip-shaped light bar 2 realize circuit communication through the circuit board installed in the groove 21 of the light bar, and several light bars 2 realize circuit communication through the circuit board installed in the groove 111 of the aluminum profile of the outer frame , and then connected to the driving power supply of the entire lamp.
