Large-area illumination LED refrigeration house lamp with good heat dissipation property

Abstract

The invention discloses a large-area illumination LED refrigeration house lamp with the good heat dissipation property. The large-area illumination LED refrigeration house lamp comprises a lamp body (1), a metal cover (2) and a lamp panel (3). The metal cover (2) is composed of a top metal ring (21) and metal supporting parts (22) uniformly connected between the top metal ring (21) and the lamp body (1). A glass cover (23) is arranged between every two adjacent metal supporting parts (22). The lamp panel (3) is arranged in a space defined by the glass covers (23) and the lamp body (1). The lamp panel (3) is detachably mounted on the lamp body (1). A plurality of LED light sources (4) are arranged on the lamp panel (3). Heat dissipation columns (5) are arranged in the positions, matched with the LED light sources (4), of the reverse surface of the lamp panel (3). According to the large-area illumination LED refrigeration house lamp, the environment-friendly and energy-saving LED lamps are adopted; the heat dissipation columns are arranged in the positions, matched with the LED lamps, of the reverse surface of the lamp panel; independence of heat dissipation of the LED light sources is guaranteed; the phenomenon of temperature accumulation at the center point of the lamp panel is effectively eliminated; and the service life of the LED lamps is prolonged.

Description

technical field [0001] The invention belongs to the technical field of LEDs, in particular to a large-area lighting LED cold storage lamp with good heat dissipation. Background technique [0002] LED is the abbreviation of light emitting diode in English. Its basic structure is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver or gold wires. , and then sealed with epoxy resin around to protect the internal core wire, and finally install the shell. Has the following advantages: [0003] 1. Energy saving: the energy consumption of white light LED is only 1 / 10 of incandescent lamp and 1 / 4 of that of energy-saving lamp; it adopts super bright and high-power LED light source, cooperates with high-efficiency power supply, and saves more than 80% of electricity than traditional incandescent lamp, the same Brightness under power is 10 times that of incandesce...

Problems solved by technology

However, the heat dissipation aluminum of the existing LED lamp adopts an integrated type, that is, the high-power LED lamp is welded on the aluminum base plate, and the whole aluminum base plate dissipates heat through an integrated heat sink. This heat dissipation structure causes the temperature at the center point of the lamp panel to accumulate. Easily damaged LED lights
