Embodiment 1

[0027] In this example, see Figure 1 to Figure 5 , a combined LED street lamp, including a housing 1, a power supply chamber 11 and a power supply 12, the power supply 12 is fixedly installed in the power supply chamber 11, the LED lamp is assembled and connected by a series of independent LED lamp modules, each LED lamp module Each group is composed of a short support plate 2, a modular heat sink 3, a heat sink fixing plate 4 and an LED lighting unit. A series of LED chips 5 are arrayed and packaged on a ceramic substrate 7, and a lens is added to each LED chip 5. 6 for light distribution, the ceramic substrate 7 is fixedly connected to the modular heat sink 3 through thermal conductive glue 8 and screws, the glass plate 9 is fixedly connected to the modular heat sink 3, and the radiator fixing plate 4 connects the modular heat sink 3 and the glass plate The gaps between 9 are enclosed to form a waterproof and dustproof sealed cavity, that is, the wall surface of the glass p...

Embodiment 2

[0031] This embodiment is basically the same as Embodiment 1, especially in that:

[0032] In this embodiment, the power supply 12 is also provided with an over-temperature protection circuit. When the temperature of the power supply 12 exceeds the warning temperature of 80° C., the power supply 12 will automatically cut off the power, so that the temperature of the LED chip 5 can be controlled within a certain range and It will not burn out due to infinite rise, and can better protect the LED chip 5 and improve the working life of the LED chip 5 .

Embodiment 3

[0034] This embodiment is basically the same as the previous embodiment, and the special features are:

[0035] In this embodiment, the rain-shielding shell is installed on the short support plate 2 of the LED lamp module, and a heat dissipation gap is kept between the rain-shielding shell and the modular radiator 3, and the front end part of the shell 1, each modular radiator 3 The rain-shielding housing and the rear end of the housing 1 are connected together to form a combined lamp housing. It is relatively simple to install the rain-shielding housing components. On the premise of not affecting heat dissipation, it can effectively protect the LED lamp module and reduce the impact of wind and rain on the short support plate. The scouring and erosion of the connection between 2 can protect the LED street lamp and improve the service life of the LED street lamp. At the same time, the rain-shielding shell can also realize the functions of partial shading and light concentrating, w...

Abstract

The invention discloses a combined LED street lamp. The LED lamp is assembled and connected by a series of independent LED lamp modules. Each LED lamp module consists of a short support plate, a modular radiator, a radiator fixing plate and The LED lamp lighting unit is composed of a short support plate fixedly installed on the cold end of the modular heat sink, and the short support plates of each LED lamp module are assembled and fixed in sequence to form a long support plate, that is, combined to form the required LED combination Lamp, and finally form the whole LED lamp. The invention can realize the free combination of street lamp power, reasonable structure, simple installation and combination, superior comprehensive performance, low processing and manufacturing costs, and realizes the diversity of lighting brightness selection. The modular combination can facilitate the disassembly and maintenance of lamps, and adapt to different ambient lighting needs.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED lamp, which is applied in the technical field of semiconductor lighting. Background technique [0002] LED has the advantages of small size, low power consumption, long service life, high brightness, low heat, environmental protection, durability, and variety. It is called the fourth-generation light source after incandescent lamps, sodium lamps, and fluorescent lamps. It is widely used in All kinds of indoor and outdoor display screens, traffic signals, tunnels, buildings, outdoor billboards, park night scenes, airports, subways, elevated overpasses and other architectural landscapes and white light lighting. LED street light is an outdoor high-power LED lamp for road lighting. The lifespan and reliability of the existing LED street lamps on the market are not ideal, and the luminous efficiency and lifespan of LEDs will be affected. Some LED street lamps have complex structures and high proces...
