Abstract

The invention discloses a lamp, comprising a radiator, an LED, a radiator cover, a rear lamp holder device, a front lamp holder device and a light transmitting face mask. The LED is adhered to the bottom surface of the radiator; the heat generated by the LED is conducted to the bottom surface and the fin of the radiator; the radiator cover is buckled with the radiator and provided with a first ventilation hole and a second ventilation hole; air is introduced by the first ventilation hole, exchanges heat with the bottom surface and the fin of the radiator and then is guided out via the second ventilation hole; the rear lamp holder device is provided with a first groove; the front lamp holder device is provided with a second groove; the air is introduced from the first groove, exchanges heat with the bottom surface and the fin of the radiator and then is guided out through the second groove; and the light transmitting hood is buckled with the radiator and transmits the light rays generated by the LED. The lamp of the invention realizes good heat radiation by using the radiator and the radiator cover; various LEDs such as a monocrystal LED chip or a polycrystalline integrated LED chip are adhered to the bottom surface of the flat radiator, so that the invention realizes good generality.

Description

technical field

[0001] The invention relates to a lamp, in particular to an outdoor lamp with good heat dissipation and capable of using a single crystal light emitting diode (Light Emitting Diode, LED) chip and a polycrystalline integrated LED chip. Background technique

[0002] Existing LED outdoor lamps are usually designed from the appearance and functional characteristics of the lamps, and can be divided into street lamps, tunnel lamps, flood lamps, garden lamps, etc.

[0003] Almost all polycrystalline luminaires adopt the form of reflective cups for optical light distribution, and the LED emitting surfaces of luminaires using this form will form a large angle.

[0004] Such as figure 1 As shown, it is a schematic diagram of the light output of the polycrystalline lamp in the prior art. The polycrystalline LED chip 91 is arranged on the sloped bottom surface 90, because if the bottom surface 90 is not designed as a sloped surface, the light 92 in the figure is not con...

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] Because the existing LED outdoor lighting fixtures do not take into account the commonality of the outdoor lighting fixtures themselves. The lamp of the present invention just takes into account the common characteristics of outdoor lamps, and can be used in various outdoor occasions to the greatest extent. At the same time, the heat dissipation structure ensures that it can be competent for the heat dissipation of single crystal LED chips and polycrystalline...
