Abstract

A lamp, includes a lamp shell and a lamp cover. Several LEDs (light-emitting diodes) are set on the lamp shell. The lamp shell defines several through-holes and the lamp cover defines several through-holes corresponding to the through-holes of the lamp shell. Heat of the LEDs dissipates through the through-holes of the lamp shell and the lamp cover to outside space.

Description

Lamp

The invention relates to the field of illumination, and in particular to a luminaire.

The light-emitting diode (LED) and organic light-emitting diode (OLED) industries are among the most watched industries in recent years. Up to now, LEDs and OLEDs have high light efficiency, low energy consumption and no pollution. Other advantages have been applied to more and more occasions, and there is a tendency to replace traditional light sources. However, once the heat generated by the light-emitting devices such as LEDs and OLEDs is accumulated, the wavelength of the light emitted by the light-emitting device may be red-shifted, and the service life may be shortened. Therefore, the luminaire must be dissipated. However, due to the blocking of the lamp housing, the heat generated by the light source is trapped in the lamp housing, resulting in poor heat dissipation.

In view of this, it is necessary to provide a luminaire with good heat dissipation performance.

A lamp comprising a lamp housing and a lamp cover combined with the lamp housing, the lamp housing is provided with a light-emitting diode, the lamp housing is provided with a through hole, and the lamp cover defines a through hole corresponding to the through hole on the lamp housing, and the light is emitted The heat emitted by the pole body is directly radiated to the outside of the lamp through the through hole of the lamp housing and the lamp cover.

The heat emitted by the light-emitting diode of the lamp of the invention can be directly dissipated to the outside of the lamp through the through hole of the lamp shell and the lamp cover, so that the heat on the lamp can be dissipated more quickly, thereby improving the heat dissipation efficiency of the lamp.

Referring to FIG. 1, an exploded view of the luminaire 100 is illustrated. The luminaire 100 includes a lamp housing 10 and a lamp cover 20. A plurality of light-emitting diodes 13 are disposed on the lamp housing 10, and the lamp cover 20 is disposed on a side of the lamp housing 10 on which the light-emitting diodes 13 are mounted to constitute the lamp 100.

The lamp housing 10 has a substantially rectangular plate shape, and an inner portion thereof has an elongated through hole penetrating through two surfaces in the thickness direction thereof. In the embodiment, the lamp housing 10 includes two first through holes 11 and two second through holes 12 . The lengths of the two first through holes 11 are longer than the lengths of the two second through holes 12. The four through holes 11, 12 are arranged side by side in the longitudinal direction in the middle of the lamp housing 10, and the long sides of the four through holes 11, 12 are parallel to the long sides of the lamp housing 10. The two second through holes 12 are vertically spaced apart from each other, and the two first through holes 11 are respectively disposed at the beginning and the end of the two second through holes 12 . The first through hole 11 and the second through hole 12 are similar in shape, and both of the long sides are parallel and equal, and the two short sides have an arc shape. Moreover, the widths of the first through hole 11 and the second through hole 12 are both much smaller than the length thereof. The plurality of light-emitting diodes 13 are disposed on two sides of the four through holes 11, 12 and arranged in two rows in a relatively aligned manner.

Referring to FIG. 2 together, another angle view of the lampshade 20 is shown. The outer shape of the lamp cover 20 matches the outer shape of the lamp housing 10. The periphery of the globe 20 is covered by a retaining wall 25 extending perpendicularly toward the lamp housing 10. The height of the retaining wall 25 is slightly greater than or equal to the thickness of the lamp envelope 10. When the lamp cover 20 is combined with the lamp housing 10, the retaining wall 25 is attached to the four boundaries of the lamp housing 10, and together forms a receiving space for receiving the LEDs 13. The retaining wall 25 also includes a fixed edge 26 disposed parallel to the retaining wall 25. The height of the fixed edge 26 is approximately equal to the height of the light-emitting diode 13 and is not greater than the height of the retaining wall 25. The fixing edge 26 is provided with a plurality of fixing holes 24 for fixing the lamp cover 20 to the lamp housing 10. A through hole is opened in the middle of the lamp cover 20. In the embodiment, the lamp cover 20 is provided with two first through holes 21 and two second through holes 22 corresponding to the four through holes 11 and 12 of the lamp housing 10. The arrangement positions and shapes of the two first through holes 21 and the two second through holes 22 of the lamp cover 20 are the same as the two first through holes 11 and the two second through holes 12 of the lamp housing 10. The four through holes 21, 22 are surrounded by a fixing ring 27. The retaining ring 27 surrounds the periphery of each of the through holes 21, 22. The height of the retaining ring 27 is smaller than the height of the retaining wall 25. When the lamp cover 20 is combined with the lamp housing 10, the fixing ring 27 does not contact the lamp housing 10. The lamp cover 20 further includes a plurality of lenses 23 distributed on both sides of the four through holes 21, 22. Each lens 23 corresponds to each of the light-emitting diodes 13 on the lamp housing 10. The lens 23 is integrally formed at the time of manufacture of the globe 20. A dimming substance such as phosphor powder may be incorporated into the inside of the lens 23.

When the lamp 100 is assembled, the lamp cover 20 is combined with the lamp housing 10, and the screw is locked to the lamp housing 20 and the lamp housing 10 through the fixing hole 24. The lens 23 of the globe 20 covers the light-emitting diode 13 of the lamp housing 10. The four through holes 21, 22 of the lamp cover 20 are aligned with the four through holes 11, 12 of the lamp housing 10 to form a through heat dissipation passage. Since the height of the fixing ring 27 surrounding the four through holes 21, 22 of the lamp cover 20 is smaller than the height of the retaining wall 25, after the lamp cover 20 is combined with the lamp housing 10, the retaining wall 25 is not abutted against the mounted light emitting diode 13 of the lamp housing 10. The accommodating space enclosed by the lampshade 20 and the lamp housing 10 is electrically connected to the outside of the luminaire 100 through the through holes 11, 12, 21, and 22. Therefore, the heat generated when the light-emitting diode 13 operates can be directly radiated to the outside through the four through holes 21 and 22 of the lamp cover 20 and the four through holes 11 and 12 of the lamp housing 10. Further, since the through holes 21, 22, 11, 12 of the lamp cover 20 and the lamp housing 10 are vertically disposed correspondingly, a chimney effect can be formed to discharge hot air from the through holes 11 and 12 of the lamp housing 10 (setting the lamp) When the lamp housing 10 is in use above the lamp cover 20, cold air enters from the through holes 21, 22 of the lamp cover 20, thereby improving heat dissipation efficiency. Further, since the lens 23 is doped with the light-adjusting substance, the light emitted from the light-emitting diode 13 passes through the lens 23, and the color temperature is changed to make it more suitable for lighting. Further, the lens 23 is integrally formed at the time of manufacture of the globe 20, thereby saving the step of separately producing the lens 23 and assembling the lens 23.
