Description

An integrated LED bracket light with a large irradiation angle

technical field

The utility model relates to the lighting field, in particular to an integrated LED bracket lamp with a large irradiation angle.

Background technique

LED lamps are widely used in various lighting fields because of their advantages of low energy consumption, small size, and no pollution. Existing LED bracket lamps, such as T5, T8, etc., in order to solve the problems of point light sources and glare, etc., mostly install a translucent cover with a semicircular cross section on the heat dissipation aluminum bracket. Since the light-transmitting cover is a semi-circular cover in cross section (the arc center angle of the cross section is 180 degrees), as shown in Figure 4, the irradiation angle of the LED tube is less than 180 degrees, generally between 116 degrees and 160 degrees In addition, the two sides of the heat-dissipating aluminum bracket block the light on both sides of the LED lamp to form a dark area, so the actual irradiation angle will be smaller, and it is difficult to meet the lighting requirements of consumers for different places.

Contents of the invention

The purpose of this utility model is to solve the above existing problems and deficiencies, to provide a large-area uniform light output effect that can significantly increase the light irradiation angle, which can reach more than 200 degrees, without dark areas on both sides, without glare and bright spots. High, easy processing, low production cost, and easy disassembly and assembly of integrated LED bracket lights. the

The technical scheme of the utility model is achieved in that:

The integrated LED bracket lamp with large irradiation angle described in the utility model includes a profile bracket and an LED light-emitting board installed on the profile bracket, a power drive device and a light-transmitting cover for the LED light-emitting board, which is characterized in that The translucent cover is an arc-shaped cover whose cross-section arc angle is greater than 240 degrees but less than 300 degrees, and the two sides of the translucent cover are detachably connected to the profile bracket through a buckle structure superior.

Among them, the optimal solution for the arc center angle of the cross-section of the arc-shaped cover body is 270 degrees, that is, a lampshade with a 3/4 circumference, so that a large-area uniform light output effect of almost 270 degrees can be achieved when used, and the light efficiency is high.

As for the above-mentioned fastening structure, it can be set according to the specific requirements of the user. In order to make the structure of the utility model simpler, the above-mentioned fastening structure is formed by inner folded edges integrally formed on both sides of the above-mentioned light-transmitting cover, and the above-mentioned profile Corresponding to the positions of the two sides of the above-mentioned LED light-emitting board, the bracket is provided with buckle grooves corresponding to the said buckle edge matching device.

Because the utility model adopts the arc-shaped cover body with the arc center angle of the cross section greater than 240 degrees and less than 300 degrees as the light-transmitting cover structure of the LED lamp tube, the utility model is in use. When the light source emits light through the light-transmitting cover, the included angle of the light-emitting surface is an obtuse angle greater than 200 degrees, so the irradiation angle is greatly expanded, at least 20% of the light-emitting area of the lamp is increased, and a large area of uniform light is achieved, which can meet different occasions The actual lighting needs of the existing LED tubes have effectively solved the problems of the light emitting surface of the existing LED lamp tube being less than 180 degrees, the light emitting surface is small, there are dark areas on both sides, and the light efficiency is low. The utility model has the advantages of simple and reliable structure, easy processing and disassembly, and large light emitting surface, and can be widely used in various lighting fields.

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

Detailed ways

As shown in Figures 1-3, the integrated LED bracket lamp with a large irradiation angle described in the utility model includes a profile bracket 1 and an LED light-emitting board 2 installed on the profile bracket 1, a power drive device 5, and an end cover 4 And the light-transmitting cover 3 of the LED light-emitting board 2 of the outer cover, in order to effectively expand the light-emitting surface of the utility model in use, the light-transmitting cover 3 has an arc center angle of its cross section greater than 240 degrees and less than 300 degrees. The arc-shaped cover body, and the two sides of the light-transmitting cover 3 are detachably connected to the profile support 1 through a buckle structure. In the process of using the utility model, when the light source on the LED light-emitting board emits light through the light-transmitting cover, the included angle of the light-emitting surface is an obtuse angle greater than 200 degrees, so the irradiation angle is greatly expanded, and uniform light output in a large area is achieved. It can meet the actual lighting needs of different occasions. The above-mentioned LED light-emitting board 2 is formed by a strip-shaped board and LED lamp beads installed on the strip-shaped board. Wherein the preferred solution of the above-mentioned light-transmitting cover is: the arc center angle of the cross-section of the arc-shaped cover body is 270 degrees, so that a large-area uniform light output effect of almost 270 degrees can be achieved when used. As for the above-mentioned fastening structure, it can be set according to the specific requirements of the user. In order to make the structure of the present utility model simpler, the above-mentioned fastening structure is formed by the inner folding edges 31 integrally formed on the two sides of the above-mentioned light-transmitting cover 3 respectively. The above-mentioned The profile support 1 is provided with buckle grooves 11 corresponding to the buckle edges 31 at the positions corresponding to the two sides of the above-mentioned LED light-emitting board 2 . In order to make the connection structure between the light-transmitting cover 3 and the profile bracket 1 more reliable and more convenient to disassemble, the above-mentioned buckle groove 11 is integrally formed on the upper surface of the profile bracket 1 and is a long slot opening outward. The above-mentioned light-transmitting cover 3 generally adopts a high light-transmitting PC cover. The lampshade structure of the integrated bracket designed by the utility model (as shown in Figure 3) is a 3/4 circle lampshade, compared with the 1/2 circle lampshade widely used in the market (attached figure 4), there are The following three obvious advantages: (1) This lampshade realizes the lighting of the lamp in the range of 270 degrees, instead of the traditional range of less than 180 degrees; the lamp has no dead angle when used in lighting places. Under the condition of achieving the same lighting effect, the application of this lampshade can reduce the number of lamps by 25%; (2) The design of this lampshade increases the luminous area of the lamp by 20%. With the same number of LED lamp beads and the same lamp power, the luminous flux output by the lamp is increased by 8%; (3) It is precisely because of the utility model that the translucent cover is transformed from the original semicircle to a 3/4 circular structure , so that the distance between the LED lamp beads and the light-emitting surface of the light-transmitting cover is increased to 13mm; it is about 3mm higher than that of traditional products (within 10mm); thus, in the case of the same number of lamp beads, (this prototype uses 88 LEDs) Lamp beads,) The surface of this lampshade emits light evenly, without glare and bright spots.

The utility model has the advantages of simple and reliable structure, easy processing and disassembly, and large light emitting surface, and can be widely used in various lighting fields.
