At the same time, since the optical axis of the light-emitting module forms an acute angle with the light-emitting panel on the cross-section along the light-emitting panel, the emitted light of the light-emitting module can be irradiated on the entire surface of the refrigerator along the width, thereby The light distribution uniformity of the light source provided for the freezer is improved.

Description

A LED lamp for freezer

technical field

The invention relates to a lamp, in particular to an LED lamp for a freezer.

Background technique

In general daily life, various lighting devices can be seen everywhere, for example, fluorescent lamps, street lamps, table lamps, art lamps and the like. Among the above-mentioned lighting devices, traditionally, most of them use tungsten filament bulbs as light sources. In recent years, due to the rapid development of technology, light emitting diodes (LEDs) have been used as light sources. What's more, in addition to lighting equipment, for general traffic signs, billboards, car lights, etc., light-emitting diodes are also used as light sources instead. Using light-emitting diodes as a light source has the advantages of saving power and greater brightness, so it has gradually become popular in use.

With the popularity of LED lamps, LED lamps are used in more and more occasions, such as cold chains, shelves and so on. Now traditional freezers, especially freezers, use fluorescent lamps as light sources. Due to the characteristics of the fluorescent lamp, the light source provided to the freezer has poor light distribution uniformity, low light efficiency, and high power consumption.

Contents of the invention

In view of this, it is necessary to provide an LED lamp for a freezer to overcome the above disadvantages.

An LED lamp for a freezer includes a light-emitting panel, a light-emitting module spaced apart from the light-emitting panel, and an accommodating cavity for setting the light-emitting module. On a cross section along the light emitting panel, the optical axis of the light emitting module forms an acute angle with the light emitting panel.

Compared with the prior art, the LED lamp for the freezer can improve the light efficiency and reduce the power consumption because the LED lamp is used as the light source. At the same time, since the optical axis of the light-emitting module forms an acute angle with the light-emitting panel on the cross-section along the light-emitting panel, the emitted light of the light-emitting module can be irradiated on the entire surface of the refrigerator along the width, thereby The light distribution uniformity of the light source provided to the freezer is improved.

detailed description

Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the specific embodiments described here are only examples, and are not intended to limit the protection scope of the present invention.

Please refer to FIG. 1 and FIG. 2 , which are schematic structural diagrams of an LED lamp 100 for a freezer provided by the present invention. The LED lamp 100 for a freezer includes a light emitting panel 11, a light emitting module 12 spaced apart from the light emitting panel 11, an accommodating cavity 13 for setting the light emitting module 12, and two The clips 14 on both sides of the accommodating cavity 13 . It is conceivable that the LED lamp 100 also includes other components, such as end caps disposed at both ends of the LED lamp 100 , electrical components, etc., which will not be repeated here.

The light emitting panel 11 is used to emit the light emitted from the light emitting module 11 while protecting the light emitting module 12 . The light-emitting panel 11 can be made of resin, plastic, etc. with a certain light transmittance. In this embodiment, the light-emitting panel 11 is made of plastic with a light-emitting rate of less than 95% and greater than 50%.

The light emitting module 12 includes a circuit board 121 and an LED lamp 122 electrically connected and fixed on the circuit board 121 . The circuit board 111 may be a printed circuit board (Printed Circuit Board, PCB), on which circuits or other electronic components, such as diodes, triodes, etc., are arranged to supply rated current or control signals to the LED lamp. The circuit board 121 is fixedly arranged in the accommodating cavity 13 described below, and the LED lamp 122 is fixedly arranged on the circuit board 121 . As is well known, each LED lamp 122 includes an optical axis 123, which becomes a reference axis for lighting design or light distribution. Since the circuit board 111 and the LED lamp 122 are in the prior art, details are not repeated here. The light emitting module 12 is spaced apart from the light emitting panel 11 to meet the requirement of light distribution. The distance between the light-emitting module 12 and the light-emitting panel 11 is determined according to the requirement of light distribution, specifically, the distance can be determined according to the width of the refrigerator. According to the directionality of the light emitted by the LED lamp 122, in order to enable the LED lamp 100 to illuminate the entire surface along the width direction of the freezer, on the section along the light emitting panel 11, the optical axis 123 of the light emitting module 12 is in line with the light emitting The panels 11 form an acute angle a. Simultaneously

The accommodating cavity 13 can be integrally formed with the light emitting panel 11 to improve the waterproof level of the LED lamp 100 . Of course, it is conceivable that if the waterproof level is not required or not required, the accommodating cavity 13 may be connected to the light emitting panel 11 by other methods, such as welding or fastening. On the cross section along the light emitting panel 11, the accommodating cavity 13 includes an upper support edge 131 connected to the light emitting panel 11 at one end, and a setting edge for setting the light emitting module 12 and opposite to the light emitting panel 11. 132, and a lower supporting edge 133 connected to the setting edge 132. One end of the setting side 132 is connected to the other end of the upper supporting side 131 . The other end of the setting side 132 is in contact with the lower supporting side 133 . One end of the lower supporting edge 133 is in contact with the light emitting panel 11 to form a continuous cavity for setting the light emitting module 12 and light distribution. In the cross-section along the light emitting panel 11 , the upper supporting edge 131 is perpendicular to the light emitting panel 11 to prevent the emitted light of the light emitting module 12 from reaching people's eyes. On the cross section along the light emitting panel 11 , the lower supporting edge 133 is parallel to the optical axis of the light emitting module 12 . Since the LED lamp 100 will project the outgoing light onto the entire surface along the width of the freezer, when the lower supporting edge 133 is parallel to the optical axis of the light-emitting module 12, the lower supporting edge 133 will not block the The main light beam emitted by the light-emitting module 12 , that is, most of the light is emitted from the light-emitting panel 11 except for a small part of stray light.

The clamping member 14 can also be integrally formed with the light-emitting panel 11 , that is, the clamping member 14 , the light-emitting panel 11 , and the accommodating cavity 13 are all extruded from plastic to form a long tubular structure. The engaging member 14 is S-shaped along the cross-section of the light emitting panel 11 . It is conceivable that a card slot (not shown in the figure) is correspondingly provided in the freezer in which the LED lamp 100 is installed. When installing, directly insert the two clips 14 of the LED lamp 100 into the slots to complete the installation of the LED lamp 100 . In order to further increase the stability of the engaging member 14 and the slot, a protrusion 141 is further provided on a side of the engaging member 14 facing away from the accommodating cavity 13 . When the engaging member 14 is inserted into the engaging slot, the protrusion 141 can be engaged in the engaging slot, thereby further enhancing the stability between the engaging member 14 and the engaging slot.

Compared with the prior art, the LED lamp 100 for the freezer can improve the light efficiency and reduce the power consumption because the LED lamp is used as the light source. At the same time, since the optical axis of the light-emitting module 12 forms an acute angle with the light-emitting panel 11 on the cross-section along the light-emitting panel 11, the emitted light of the light-emitting module 12 can illuminate the entire width of the refrigerator. surface, thereby improving the light distribution uniformity of the light source provided to the freezer.
